    Interventional radiology has seen rapid growth in cardiology and represents an alternative to hazardous surgery. Recently there has been a substantial growth in the number of procedures being performed and interventional cardiology (IC) procedures are the most common interventional procedures in Europe. Advances in imaging technology have facilitated the development of increasingly complex radiological IC equipment. Currently, the technology is developing at a rate ahead of supporting research, equipment standards and a regulatory framework. International standards play a key role in the design, manufacture and performance of radiological IC equipment. A survey of 12 IC systems (15 imaging chains) was conducted in Irish hospitals. The aim of the study was to assess the imbalance between rapidly advancing technology and existing standards and to propose recommendations for new IC equipment standards. The results demonstrate the need for definitive equipment requirements and standardisation in the design, manufacture, acceptance and maintenance of IC equipment. (authors)

    Apart from its benefits, the interventional cardiology (IC) is known to generate high radiation doses to patients and medical staff involved. The European Union Medical Exposures Directive 97/43/EURATOM strongly recommend patient dosimetry in interventional radiology, including IC. IC patient radiation doses in four representative IC rooms in Croatia were investigated. Setting reference levels for these procedures have difficulties due to the large difference in procedure complexity. Nevertheless, it is important that some guideline values are available as a benchmark to guide the operators during these potentially high-dose procedures. Local and national diagnostic reference levels (DRLs) were proposed as a guidance. A total of 138 diagnostic (coronary angiography, CA) and 151 therapeutic (PTCA, stenting) procedures were included. Patient irradiation was measured in terms of kerma-area product (KAP), fluoroscopy time (FT) and number of cine-frames (F). KAP was recorded using calibrated KAP-meters. DRLs of KAP, FT and F were calculated as third quartile values rounded up to the integer. Skin doses were assessed on a selected sample of high skin dose procedures, using radiochromic films, and peak skin doses (PSD) were presented. A relative large range of doses in IC was detected. National DRLs were proposed as follows: 32 Gy cm 2 , 6.6 min and 610 frames for CA and 72 Gy cm 2 , 19 min and 1270 frames for PTCA. PSD 2 Gy in 8% of selected patients. Measuring the patient doses in radiological procedures is required by law, but rarely implemented in Croatia. The doses recorded in the study are acceptable when compared with the literature, but optimisation is possible. The preliminary DRL values proposed may be used as a guideline for local departments, and should be a basis for radiation reduction measures and quality assurance programmes in IC in Croatia.

    Cardiovascular diseases are the first cause of death in Spain. The most usual procedures in interventional cardiology are coronariography and PTCA. The first is a diagnostic technique, and the second one is interventional. Our goal has been to study procedures made during the first six months in the Interventional Cardiology Unit of the Juan Ramon Jimenez Hospital (Huelva-Spain), taking into account radiation protection issues. We have studied 178 patients; 145 of them underwent coronariography, and 33 of the patients had PTCA too. Every case was analyzed taking into account technical and dosimetric parameters. We show parameters values gathered: Diagnostic techniques (valvular and non-valvular patients), and interventional techniques (coronariography and PTCA in different or in the same intervention). Higher doses were obtained with valvular patients, although the number of frames was similar. Attending to therapeutic procedures, the highest values were gotten with the 'double' interventions. Interventional procedures exceed in 60% doses gotten in diagnostic studies: this is because of the number of series and number of frames per series. Similar values obtained by other authors have been gotten. (author)

    Quality assurance in clinical studies aiming at approval of pharmaceutical products is submitted to strict rules, controls and auditing regulations. Comparative instruments to ensure quality in diagnostic and therapeutic procedures are not available in interventional cardiology, likewise in other fields of cardiovascular medicine. Quality assurance simply consists of "quality registers" with basic data not externally controlled. Based on the experiences of clinical studies and their long history of standardization it is assumed that these data may be severely flawed thus being inappropriate to set standards for diagnostic and therapeutic strategies. The precondition for quality assurance are quality data. In invasive coronary angiography and intervention medical indications, the decision making process interventional versus surgical revascularization, technical performance and after - care are essential aspects affecting quality of diagnostics and therapy. Quality data are externally controlled data. To collect quality data an appropriate infrastructure is a necessary precondition which is not existent. For an appropriate infrastructure investments have to be done both to build up as well as to sustain the necessary preconditions. As long as there are no infrastructure and no investments there will be no "quality data". There exist simply registers of data which are not proved to be a basis for significant assurance and enhancement in quality in interventional coronary cardiology.

    As interventional cardiology can induce high doses not only for patients but also for the personnel, the delimitation of regulated areas (or zoning) and workstation analysis (dosimetry) are very important in terms of radioprotection. This paper briefly recalls methods and tools for the different steps to perform zoning and workstation analysis. It outlines the peculiarities of interventional cardiology, presents methods and tools adapted to interventional cardiology, and then discusses the same issues but for workstation analysis. It also outlines specific problems which can be met, and their possible adapted solutions

    Exploring the discrepancy in sex-ratio among interventional cardiologists by analysing the population of the female interventionalist. Despite an increase number of women who graduate from medical school in France during the last generation today, women represent only 24% of all cardiologists and 3% are interventional cardiologists. To face this international gender-based issue of interventional cardiology, committees were established in US (WIN) and recently within the EAPCI: the Women EAPCI chaired by Drs Mehilli and Mauri. In France, the Intervention'Elles committee emerged in order to participate in this concern. As a first initiative, the Intervention'Elles group launched an e-survey to obtain information on the population of French female interventional cardiologists, focused on demography, work patterns, maternity and radiation exposure. Mean age is 40 years old (±7,4), 68% are working in large volume center, 28% have also structural interventional activity. Only 40% have left arm coverage. Despite 80% of French female interventional cardiologists wear personal dosimeters only 45% of them have a dosimetry feedback. Interestingly, even if 54% of women have children (mean: 1.9±1) 28% of them report that childbearing had interfered with their career plan. This questionnaire identifies for the first time the women population in interventional cardiology in France and highlights some of the issues encountered in more detail. This first descriptive step would help to develop strategies for attaining gender equality in interventional cardiology. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    The increasing of procedures using fluoroscopy in interventional cardiology procedures may increase medical and patients to levels of radiation that manifest in unintended outcomes. Such outcomes may include skin injury and cancer. The cardiologists and other staff members in interventional cardiology are usually working close to the area under examination and they receive the dose primarily from scattered radiation from the patient. Mexico does not have a formal policy for monitoring and recording the radiation dose delivered in hemodynamic establishments. Deterministic risk management can be improved by monitoring the radiation delivered from X-ray devices. The objective of this paper is to provide cardiologist, techniques, nurses, and all medical staff an information on DR levels, about X-ray risks and a simple a reliable method to control cumulative dose.

    During the last 10 years, there have been major technological achievements in pediatric interventional cardiology. In addition, there have been several advances in cardiac imaging, especially in 3-dimensional imaging of echocardiography, computed tomography, magnetic resonance imaging, and cineangiography. Therefore, more types of congenital heart diseases can be treated in the cardiac catheter laboratory today than ever before. Furthermore, lesions previously considered resistant to interventional therapies can now be managed with high success rates. The hybrid approach has enabled the overcoming of limitations inherent to percutaneous access, expanding the application of endovascular therapies as adjunct to surgical interventions to improve patient outcomes and minimize invasiveness. Percutaneous pulmonary valve implantation has become a successful alternative therapy. However, most of the current recommendations about pediatric cardiac interventions (including class I recommendations) refer to off-label use of devices, because it is difficult to study the safety and efficacy of catheterization and transcatheter therapy in pediatric cardiac patients. This difficulty arises from the challenge of identifying a control population and the relatively small number of pediatric patients with congenital heart disease. Nevertheless, the pediatric interventional cardiology community has continued to develop less invasive solutions for congenital heart defects to minimize the need for open heart surgery and optimize overall outcomes. In this review, various interventional procedures in patients with congenital heart disease are explored.

    Interventional cardiology procedures are classified as high-dose procedures, owing to increased risk for radiation skin injuries and stochastic effects, such as cancer. European MED Directive 97/43 requires special consideration and dose evaluation for this kind of procedures . Dose received by a patient, in general, depends on the radiological equipment, examination protocol, the way it is implemented, the patient's body weight and nature of disease. Long-term fluoroscopy of certain parts of the body, a significant body mass, high-value dose intensity, continuous rather than pulsed fluoroscopy, small focus-skin distance and repeated procedure on the same patient, are among the factors that can lead to radiation skin injuries. A particular challenge is the fact that the radiation damage of the skin is difficult to detect and connect to the previously conducted cardiologic procedures. The fact that such injuries do not have immediate manifestation is very often reason that many of them remain undetected. The purpose of this work is to assess the level of radiation dose to patients in percutaneous coronary interventions (PCI) and to investigate possibility for setting of a practical trigger value if dose quantities exceed certain levels in terms of dose descriptors available at display of interventional cardiology unit. Two dedicated interventional cardiology units in a large teaching cardiac centre (Clinical Centre of Serbia, Belgrade, Serbia) were included in the survey. Both rooms (D and F) were equipped with X-ray units of the identical model: Siemens Axiom Artis (Siemens, Erlangen, Germany) with the flat panel detector and integrated ionization chamber to measure air kerma-area product (P K A) and air kerma in international reference point (K I RP). Patient doses were assessed in terms of P K A, K I RP and maximum-skin dose (MSD). P K A and K I RP were assessed using a built-in, in situ calibrated dosimeters, while MSD was estimated using radiochromic films

    In September 2000, an expert mission was assigned to Chile, under the regional project named 'International BBS in Medical Practices Radiation Protection and Quality Assurance In Interventional Radiology' (ARCAL XLIX). The objective of the mission was to evaluate the level of radiation protection (RP) and safety in interventional cardiology ( IC ) installations. A team of local cardiologists, medical physicists and technologists was created for this purpose and during one week, several cardiology laboratories were evaluated and some basic quality controls (QC) were carried out. A basic pilot training course in radiation protection was imparted at the Hospital of the University of Chile in Santiago de Chile and some of the key objectives for a future national quality assurance programme were presented during the national congress of IC. In addition, a national survey on radiation protection aspects was circulated and its results evaluated. These activities enabled the local team to become familiar with the methodology of assessment of the level of protection and the organization of a programme, which was illustrated with the examples of similar European programmes. As result of these actions, several proposals were made to both the local authorities and the IAEA. The most important were: a) to initiate a basic QC programme, b) to organize a training in RP for cardiologists in order to formalize their accreditation, c) to improve personal occupational dosimetry, d) to initiate a programme of patient dosimetry, e) to optimize the technical and clinical protocols, f) to create a national registry of incidents with skin injuries.

  11. Interventional Cardiology for Congenital Heart Disease.

    Congenital heart interventions are now replacing surgical palliation and correction in an evolving number of congenital heart defects. Right ventricular outflow tract and ductus arteriosus stenting have demonstrated favorable outcomes compared to surgical systemic to pulmonary artery shunting, and it is likely surgical pulmonary valve replacement will become an uncommon procedure within the next decade, mirroring current practices in the treatment of atrial septal defects. Challenges remain, including the lack of device design focused on smaller infants and the inevitable consequences of somatic growth. Increasing parental and physician expectancy has inevitably lead to higher risk interventions on smaller infants and appreciation of the consequences of these interventions on departmental outcome data needs to be considered. Registry data evaluating congenital heart interventions remain less robust than surgical registries, leading to a lack of insight into the longer-term consequences of our interventions. Increasing collaboration with surgical colleagues has not been met with necessary development of dedicated equipment for hybrid interventions aimed at minimizing the longer-term consequences of scar to the heart. Therefore, great challenges remain to ensure children and adults with congenital heart disease continue to benefit from an exponential growth in minimally invasive interventions and technology. This can only be achieved through a concerted collaborative approach from physicians, industry, academia and regulatory bodies supporting great innovators to continue the philosophy of thinking beyond the limits that has been the foundation of our specialty for the past 50 years.

  12. Advanced Imaging of Intracranial Atherosclerosis: Lessons from Interventional Cardiology

    Full Text Available Intracranial atherosclerosis is a major cause of ischemic stroke. Patients with a high degree of stenosis have a significant rate of stroke despite medical therapy. Two randomized trials of stenting have failed to show benefit. Improving periprocedural complication rates and patient selection may improve stenting outcomes. Fractional flow reserve (FFR, intravascular ultrasound (IVUS, and optical coherence tomography (OCT are intravascular imaging techniques employed to improve patient selection and stent placement in interventional cardiology. FFR has been shown to improve cardiovascular outcomes when used in patient selection for intervention. Studies of FFR in intracranial atherosclerosis show that the measure may predict which plaques lead to stroke. IVUS is used in cardiology to quantify stenosis and assist with stent placement. Comparisons with histology show that it can reliably characterize plaques. Several case reports of IVUS in intracranial arteries show the technique to be feasible and indicate it may improve stent placement. Plaque characteristics on IVUS may help identify vulnerable plaques. In interventional cardiology, OCT provides excellent visualization of vessel geometry and is useful periprocedurally. Images reliably identify thin-capped fibroatheromas and other plaque features. Case reports indicate that OCT is safe for use in intracranial arteries. OCT can be used to identify perforator vessels and so may be useful in avoiding perforator strokes, a common complication of stenting. Plaque characteristics on OCT may be useful in patient selection.

    There have been substantial improvements made in the tools and techniques used since the advent of percutaneous coronary intervention. What was primarily developed as a treatment of coronary artery disease is now used to address a variety of structural heart disease problems. The outcomes have been remarkably successful with relatively low complication rates that rival the results of open-heart surgery. This article will review some of the new devices available for management of structural cardiac conditions including congenital defects and acquired valvular abnormalities. Transcatheter treatment offers advantages over surgical intervention in recovery time, improved patient satisfaction, lower procedural risk, and avoidance of cardio-pulmonary bypass especially in high-risk patients. We will discuss different medical conditions and introduce the devices used to treat these conditions. Each device or technique has benefits and risks, and familiarity with the devices along with patient selection will best optimize the outcome. Copyright © 2014 Japanese College of Cardiology.

    2015-01-01

    Recent ICRP publications have reviewed evidence for induction of heart disease. Studies suggest the threshold dose to the heart may be as low as 500 mGy. Doses to the heart from paediatric interventional procedures performed in Glasgow between April 2012 and July 2013 to correct congenital heart defects were investigated to assess the level of potential risk of cardiovascular disease. For common procedures, doses were found to be typically less than 50 mGy, with the highest dose in the period for which data are available estimated to be 330 mGy. These results suggest that any increased risk due to paediatric interventional cardiology is likely to be small, but cumulative doses over a number of years could reach the threshold for effects.

    2013-01-01

    Concerns about ionizing radiation during interventional cardiology have been increased in recent years as a result of rapid growth in interventional procedure volumes and the high radiation doses associated with some procedures. Noncancer radiation risks to cardiologists and medical staff in terms of radiation-induced cataracts and skin injuries for patients appear clear potential consequences of interventional cardiology procedures, while radiation-induced potential risk of developing cardiovascular effects remains less clear. This paper provides an overview of the evidence-based reviews of concerns about noncancer risks of radiation exposure in interventional cardiology. Strategies commonly undertaken to reduce radiation doses to both medical staff and patients during interventional cardiology procedures are discussed; optimisation of interventional cardiology procedures is highlighted.

    The number of cardiology interventional procedures has significantly increased recently. This is due to the reliability of the diagnostic equipment to diagnose many heart disease. In the procedures the x-ray used results in increasing radiation doses to the staff. The cardiologists and other staff members in interventional cardiology are usually working close to the area under examination and receive the dose primarily from scattered radiation from the patient. Therefore workers in interventional cardiology are expected to receive high doses. This study overviews the status of occupational exposure at the three cardiology centers at three different hospitals in Khartoum compared with that received by workers at other medical practices (radiotherapy, nuclear medicine and diagnostic radiology) in the Institute of Nuclear and Technology (INMO) at El Gezira. The TLD Harshaw 6600 reader was used in the assessment of effective dose for Hp (10). Two TLDs were used by each worker at the three cardiology centres, one worn under a protective apron and the other worn outside and above the apron as specified by the ICRP. Each worker at the other sections was facilitated with one dosimeter to be worn on the chest. The annual doses received by 14 cardiologists, 13 nurses and 9 technologists at the three cardiology centres were in the range: (0.84-4.77), (0.15-2.08), (0.32-1.10) mSv respectively. In the INMO the annual doses received by 7 doctors, 5 nurses and 14 technologists were in the range: (0.12-0.51), (0.11-0.65), (0.03-1.39) mSv respectively. The results showed that the annual doses received by the workers do not exceed 20 mSv. The study also indicated that doses received by workers in interventional cardiology, in particular the cardiologists are high compared to that received at the other medical sections.(Author)

    Interventional cardiology has finally completed, after 26 years of advocacy, a professional hat trick: independent board certification, membership as a unique specialty in the American Medical Association House of Delegates (AMA HOD), and recognition by the Centers for Medicaid and Medicare Services (CMS) as a separate medical specialty. This article points out how these distinctions for interventional cardiology and its professional society, the Society for Cardiovascular Angiography and Interventions (SCAI), have led to clear and definite benefits for interventional cardiologists and their patients.

    2018-04-12

    Systemic inflammatory response syndrome (SIRS), initially reported after cardiovascular surgery, has been described after various interventional cardiology procedures, including endovascular/thoracic aortic repair (EVAR/TEVAR), implantation of heart rhythm devices, percutaneous coronary intervention (PCI), electrophysiology procedures (EP), and transcatheter aortic valve implantation (TAVI). In these settings, a comprehensive understanding of the triggers, pathogenesis as well as a common diagnostic/therapeutic algorithm is lacking and will be discussed in this review. SIRS occurs in about 40% and 50% of patients undergoing TEVAR/EVAR and TAVI respectively; it affects 0.1% of patients undergoing implantation of heart rhythm devices. Prevalence is unknown after PCI or EP. Clinical presentation includes fever, dyspnoea/tachypnoea, tachycardia, weakness, chest pain and pericardial/pleural effusion. Several triggers can be identified, related to implanted devices, biomaterial, and procedural aspects (prolonged hypotension, aneurysm thrombus manipulation, active fixation atrial leads, coronary microembolization, balloon dilatation/stent implantantation, contrast medium, coronary/myocardial microperforation). Nonetheless, these triggers share three main pathogenic pathways leading to SIRS clinical manifestations: leucocytes activation, endothelial injury/activation, and myocardial/pericardial injury. Therapy consists of non-steroidal agents, with corticosteroids as second-line treatment in non-responders. Although a benign evolution is reported after implantation of heart rhythm devices, PCI and EP, major adverse events may occur after EVAR/TEVAR and TAVI at short- and mid-term follow up.

    The aim of this work is to determine current radiographic protocols in paediatric interventional cardiology (IC) in the UK and Ireland. To do this we investigated which imaging parameters/protocols are commonly used in IC in different hospitals, to identify if a standard technique is used and illustrate any variation in practice. A questionnaire was sent to all hospitals in the UK and Ireland which perform paediatric IC to obtain information on techniques used in each clinical department and on the range of clinical examinations performed. Ethical and research governance approval was sought from the Office for Research Ethics Committees Northern Ireland and the individual trusts. A response rate of 79% was achieved, and a wide variation in technique was found between hospitals. The main differences in technique involved variations in the use of an anti-scatter grid and the use of additional filtration to the radiation beam, frame rates for digital acquisition and pre-programmed projections/paediatric specific programming in the equipment. We conclude that there is no standard protocol for carrying out paediatric IC in the UK or Ireland. Each hospital carries out the IC procedure according to its own local protocols resulting in a wide variation in radiation dose. (paper)

    In most countries of European Union legislation requires the determination of the total skin dose to patient resulting from interventional procedures to assess the risk of deterministic effect. To this end, various dose indicators like dose area product (DAP), cumulative dose (CD) and entrance dose at the patient plane (EFD) are used in clinical practice. The study aims at relating those dose indicators with doses ascribe to the most irradiated areas of the patient skin usually expressed in terms of local maximal skin dose (MSD). For the study the local MSD and related to their areas are investigated and compared for coronary angiography CA and intervention (PCI). Two methods implying radiographic films Kodak EDR2 and matrixes of thermoluminescent dosimeters (TLDs) are applied for direct measurements of dose distribution for selected procedures. Both methods are compared. Additionally, for patient dosimetry the following data: MSD, CD, EFD, fluoroscopy time (FT), number of acquired images, total DAP, fluoro-DAP and record-DAP were collected for randomly selected procedure. The statistical quantities like: median, 3 rd quartile, mean and standard deviation for all dosimetric parameters are determined. Preliminary study showed that the values of data collected for coronary procedures are in the ranges 0,7 - 27,3 min for fluoroscopy time, 50 - 350 Gy cm 2 for total DAP, 300 - 2000 mGy for CD, 140 - 2000 mGy for EFD and 100 - 1500 mGy for local maximal skin dose. For interventions the ranges are, accordingly 3,0 - 43,6 min , 25 - 450 Gy cm 2 , 270 - 6600 mGy, 80 - 2600 mGy and 80 - 1500 mGy. As a result of the study the correlations between dose indicators and local MSD are analyzed. The concentration of dose on irradiated films are going to be investigated in some detail as well.

    In 2011 there were 658 percutaneous coronary intervention cases performed with more than 60% of the patients presenting to the hospital as an acute coronary syndrome. Most procedures consisted of balloon dilatation followed by stent deployment, and 93% of these stents were drug-eluting stents. Procedural success was achieved in 93.3% of cases and an overall major adverse cardiac events rate of 3.6%. This includes a mortality rate of (0.5%). In addition, there were 25 Core Valve procedures carried out. This is more than twice the amount of patients who had a transcatheter aortic valve implantation in 2010, reflecting the changing direction of the management of structural heart disease. © 2012 The Author; Internal Medicine Journal © 2012 Royal Australasian College of Physicians.

    The radiation doses from interventional procedures is relevant when treating children because of their greater radiosensitivity compared with adults. The purposes of this paper were to estimate the dose received by 18 pediatric patients who underwent cardiac interventional procedures and to correlate the maximum entrance surface air kerma (Ke,max), estimated with radiochromic films, with the cumulative air kerma values displayed at the end of procedures. This study was performed in children up to 6 years. The study was performed in two hospitals, one located in Recife and the other one in São Paulo. The x-ray imaging systems used were Phillips Allura 12 model with image intensifier system and a Phillips Allura FD10 flat panel system. To estimate the Ke,max on the patient’s skin radiochromic films(Gafchromic XR-RV2) were used. These values were estimated from the maximum optical density measured on film using a calibration curve. The results showed cumulative air kerma values ranging from 78.3- 500.0mGy, with a mean value of 242,3 mGy. The resulting Ke,max values ranged from 20.0-461.8 mGy, with a mean value of 208,8 mGy. The Ke,max values were correlated with the displayed cumulative air kerma values. The correlation factor R² was 0.78, meaning that the value displayed in the equipment’s console can be useful for monitoring the skin absorbed dose throughout the procedure. The routine fluoroscopy time records is not able by itself alert the physician about the risk of dose exceeding the threshold of adverse reactions, which can vary from an early erythema to serious harmful skin damage.

    Interventional radiology and cardiology belongs to the imaging modalities connected with significantly higher radiation exposure of patients and medical staff, compared to the exposure during other diagnostic procedures. The objective of this presentation is to promote typical technical parameters and parameters related to the radiation policy, used during the most frequent endovascular and cardiology procedures, as well as the monitoring of the exposure of patients. The presented study reports the results of collecting the data of monitoring doses received by 318 patients undergoing interventional examinations in 3 various departments of the Slovak National Institute of Cardiology and Vascular Diseases. There were 9 different endovascular and cardiology procedures reviewed. The reported patient's radiation exposures were established by using the KAP values, directly shown on the display of the X-ray equipment. From the measured KAP values the entrance surface doses were calculated. Equivalent doses have been measured on hands, legs and other parts of medical staff body, by using electronic dosimeters or thermoluminescent dosimeters. The presented results have covered a wide range of the measured fluoroscopy time values, different number of acquisitions used in various interventional procedures, various cumulated KAP values and also a wide range of the cumulated entrance surface doses. The occupational doses of the operators, followed during dose measurements on their left hands, covered the range from 0.1 μSv to 1513 μSv for one examination performed. The important contribution of the presented results to the radiation protection policy in the Slovak Republic is the mapping of the current situation of the radiation exposure of patients undergoing the chosen interventional examinations and the professional radiation exposure level of interventional operators, providing the most significant interventional procedures in the Slovak interventional hospitals.

    Ionizing radiation management is among the most important safety issues in interventional cardiology. Multiple radiation protection measures allow the minimization of x-ray exposure during interventional procedures. Our purpose was to assess the utilization and effectiveness of radiation protection and optimization techniques among interventional cardiologists in Lithuania. Interventional cardiologists of five cardiac centres were interviewed by anonymized questionnaire, addressing personal use of protective garments, shielding, table/detector positioning, frame rate (FR), resolution, field of view adjustment and collimation. Effective patient doses were compared between operators who work with and without x-ray optimization. Thirty one (68.9%) out of 45 Lithuanian interventional cardiologists participated in the survey. Protective aprons were universally used, but not the thyroid collars; 35.5% (n  =  11) operators use protective eyewear and 12.9% (n  =  4) wear radio-protective caps; 83.9% (n  =  26) use overhanging shields, 58.1% (n  =  18)-portable barriers; 12.9% (n  =  4)-abdominal patient's shielding; 35.5% (n  =  11) work at a high table position; 87.1% (n  =  27) keep an image intensifier/receiver close to the patient; 58.1% (n  =  18) reduce the fluoroscopy FR; 6.5% (n  =  2) reduce the fluoro image detail resolution; 83.9% (n  =  26) use a 'store fluoro' option; 41.9% (N  =  13) reduce magnification for catheter transit; 51.6% (n  =  16) limit image magnification; and 35.5% (n  =  11) use image collimation. Median effective patient doses were significantly lower with x-ray optimization techniques in both diagnostic and therapeutic interventions. Many of the ionizing radiation exposure reduction tools and techniques are underused by a considerable proportion of interventional cardiology operators. The application of basic radiation protection tools and

    Citation classics have been published in many fields of medicine; however, none have focused on interventional cardiology. The goal of this study was to identify the top 100 articles in the field of interventional cardiology and highlight their important trends and characteristics. The Scopus database was used by 2 independent reviewers to extract the top 100 articles using a variety of keywords. We found articles published between 1953 and 2012. Majority (n = 78) of the top 100 articles were published between 1996 and 2010, and the United States was affiliated with the highest number of articles in our list (n = 68). Over half (n = 54) the articles were funded. Private funding was correlated with higher citations (p = 0.036). A third (n = 33) of the papers had authors with conflicts of interest; however, conflict of interest had no effect on citations (p = 0.837). Majority (n = 57) of the articles studied coronary angioplasty and stenting; followed by coronary angiography (n = 14). Women were underrepresented, with only 11 female first authors in the top 100 papers, and only 1 female in the list of top authors who had 5 or more publications. In conclusion, the following features define the typical highly cited article in interventional cardiology-a clinical trial conducted in the United States, which studies angioplasty, and has been published relatively recently in a high-impact journal by a male first author.

    The Council Directive of the European Community 97/43/Euratom (MED) deals with the health protection of individuals against dangers of ionising radiation in relation to medical exposure, and also focuses attention on some special practices (Art. 9), including interventional radiology, a technique involving high doses to the patient. The paper presents the European approach to optimisation of exposure in interventional cardiology. The DIMOND research consortium (DIMOND: Digital Imaging: Measures for Optimising Radiological Information Content and Dose) is working to develop quality criteria for cineangiographic images, to develop procedures for the classification of complexity of therapeutic and diagnostic procedures and to derive reference levels, related also to procedure complexity. DIMOND project also includes aspects of equipment characteristics and performance and content of training in radiation protection of personnel working in interventional radiology field. (author)

    Background - The study investigated the radiation skin doses for interventional patients in cardiology; two procedures which have the highest radiation dose are Radiofrequency Catheter Ablation (RFCA) and Percutaneous Transluminal Coronary Angioplasty (PTCA). Methods and Results - 56 patients were randomly selected and investigated; 23 patients in the RFCA group and 33 in the PTCA group. Skin and effective dose were calculated from Dose Area Product (DAP). Thermoluminescent Dosimetry was the second method of dose measurement used. Patients were followed-up for a three month period to check for possible skin reactions resulting from the radiation dose during the procedure. Radiation skin doses in 14 patients were calculated to be more than 1 Gy, including three patients who received more than 2 Gy, the threshold dose for deterministic effects of radiation. 7 patients (12.5%) reported skin reactions as a result of the radiation received to their backs during the procedure. Mean DAP and estimated effective doses were 105 Gycm 2 and 22.5 mSv for RFCA, and 32 Gycm 2 and 6.2 mSv for PTCA procedures respectively. Conclusion - Complex procedures in Interventional Cardiology can exceed the threshold level for deterministic effects in the skin. (author)

    The paper summarizes results of measurements of relevant dosimetric quantities in interventional cardiology. Dosimetric data were collected for 117 coronary angiography (CA) procedures, 69 percutaneous coronary interventions (PCI) and 41 combined procedures (CA+PCI), taking into account two quantities: air kerma area product (KAP) d air kerma in international reference point (K IRP ). Mean KAP values were 78 Gy·cm 2 , 113 Gy·cm 2 and 141 Gy·cm 2 for CA, PCI i CA+PCI, respectively. Corresponding mean K IRP values were 1.2 Gy, 1.8 Gy and 2.2 Gy. With respect to high dose values, risk for stochastic effects and tissue reactions, dose management methods were proposed. (author) [sr

    The practice of interventional cardiology differs between countries and regions. In this study we report the results of the first nation-wide long-term comparison of interventional cardiology in two countries using a common web-based registry. The Swedish Coronary Angiography and Angioplasty Registry (SCAAR) was used to prospectively and continuously collect background-, quality-, and outcome parameters for all coronary angiographies (CA) and percutaneous coronary interventions (PCI) performed in Iceland and Sweden during one year. The rate of CA per million inhabitants was higher in Iceland than in Sweden. A higher proportion of patients had CA for stable angina in Iceland than in Sweden, while the opposite was true for ST elevation myocardial infarction. Left main stem stenosis was more commonly found in Iceland than in Sweden. The PCI rate was similar in the two countries as was the general success rate of PCI, achievement of complete revascularisation and the overall stent use. Drug eluting stents were more commonly used in Iceland (23% vs. 19%). The use of fractional flow reserve (0.2% vs. 10%) and the radial approach (0.6% vs. 33%) was more frequent in Sweden than in Iceland. Serious complications and death were very rare in both countries. By prospectively comparing interventional cardiology in two countries, using a common web based registry online, we have discovered important differences in technique and indications. A discovery such as this can lead to a change in clinical practice and inspire prospective multinational randomised registry trials in unselected, real world populations.

    In this study, skin dosimetry of patients undergoing interventional cardiology procedures is presented. Three hospitals were included. Two methods were used for skin dosimetry-radiochromic dosimetry films and reconstruction of skin dose distribution based on examination protocol. Maximum skin doses (MSD) obtained from both methods were compared for 175 patients. For patients for whom the film MSD was >1 Gy, the reconstruction MSD differed from the film MSD in the range of ± 50 % for 83 % of patients. For remaining patients, the difference was higher and it was caused by longer fluoroscopy time. For 59 patients for whom the cumulative dose was known, the cumulative dose was compared with the film MSD. Skin dosimetry with radiochromic films is more accurate than the reconstruction method, but films do not include X-ray fields from lateral projections whilst reconstructions do. (authors)

    Atrial fibrillation (AF) has a huge impact on clinical stroke because it is the primary cause of cardio-embolism, which constitutes ~20% of all strokes. As a result, there is a great need to explore safer and more effective primary and secondary prophylactic agents. In this article, we discuss the overlapping issues pertaining to AF from both a neurology and cardiology standpoint. We focus on the dynamic interplay of neurovascular and cardiovascular diseases in relation to AF, traditional and novel risk factors for AF leading to stroke, impact of AF on cognitive decline, and current upstream medical and surgical options for embolism prophylaxis.

    New European regulation regarding radiological protection of workers and more specifically the new occupational dose limit for the eye lens recently reduced to 20 mSv yr −1 may affect interventional cardiologists. This paper presents a set of measurements of occupational doses performed in five interventional cardiology centres and then compared with the new dose limit. The measurement of occupational doses was performed over the apron at chest level using electronic dosemeters recording H p (10). In one of the centres, scatter dose at goggles was also measured with optically stimulated luminescence dosemeters calibrated in terms of H p (0.07). An average H p (10) over the apron of 46 μSv/procedure was measured for cardiologists. Lower doses were noted in other professionals like second cardiologists, nurses or anaesthetists. Procedures for valvular and other structural heart diseases involved the highest occupational doses, averaging over 100 μSv/procedure. Important differences in occupational doses among centres may be indicative of different radiation protection habits. The new occupational dose limit for the eye lens is likely to be exceeded by those among the interventionalists who do not use protection tools (ceiling suspended screen and/or goggles) even with standard workloads.

  16. Cardiological-interventional therapy of coronary artery disease today

    The current importance of the interventional therapy of coronary artery disease may be deduced from the exponential increase in procedures performed in Germany in the last decade - at least 125,840 in 1996. Today, by improved catheter and balloon materials as well as by growing experience of the cardiologists, even complex lesions may be treated. Limitations of balloon angioplasty include acute vessel closure and restenosis - newer angioplasty devices like directional or rotational atherectomy or excimer-laser angioplasty did not overcome these limitations; only by coronary stenting, acute vessel closure could be managed and the likelihood of restenosis - at least in particular groups of patients - could be reduced. For a few years, intracoronary brachytherapy of the segments dilated with beta- or gamma-emitters has been seeking to reduce restenosis rate; the department of cardiology of the Dresden Cardiovascular Institute is participating in such a multicentre study using the beta-emitter 188 renium. Further main topics of our department represent primary angioplasty in patients with acute myocardial infarction and invasive diagnostic or interventional procedures by the transradial approach.

    Radiation dose and image quality for paediatric protocols in a biplane x-ray system used for interventional cardiology have been evaluated. Entrance surface air kerma (ESAK) and image quality using a test object and polymethyl methacrylate (PMMA) phantoms have been measured for the typical paediatric patient thicknesses (4-20 cm of PMMA). Images from fluoroscopy (low, medium and high) and cine modes have been archived in digital imaging and communications in medicine (DICOM) format. Signal-to-noise ratio (SNR), figure of merit (FOM), contrast (CO), contrast-to-noise ratio (CNR) and high contrast spatial resolution (HCSR) have been computed from the images. Data on dose transferred to the DICOM header have been used to test the values of the dosimetric display at the interventional reference point. ESAK for fluoroscopy modes ranges from 0.15 to 36.60 µGy/frame when moving from 4 to 20 cm PMMA. For cine, these values range from 2.80 to 161.10 µGy/frame. SNR, FOM, CO, CNR and HCSR are improved for high fluoroscopy and cine modes and maintained roughly constant for the different thicknesses. Cumulative dose at the interventional reference point resulted 25-45% higher than the skin dose for the vertical C-arm (depending of the phantom thickness). ESAK and numerical image quality parameters allow the verification of the proper setting of the x-ray system. Knowing the increases in dose per frame when increasing phantom thicknesses together with the image quality parameters will help cardiologists in the good management of patient dose and allow them to select the best imaging acquisition mode during clinical procedures.

    The objective of this work is to assess the occupational dose in interventional cardiology in a large hospital in Belgrade, Serbia. A double-dosimetry method was applied for the estimation of whole-body dose, using thermoluminescent dosemeters, calibrated in terms of the personal dose equivalent H p (10). Besides the double-dosimetry method, eye dose was also estimated by means of measuring ambient dose equivalent, H*(10), and doses per procedure were reported. Doses were assessed for 13 physicians, 6 nurses and 10 radiographers, for 2 consequent years. The maximum annual effective dose assessed was 4.3, 2.1 and 1.3 mSv for physicians, nurses and radiographers, respectively. The maximum doses recorded by the dosemeter worn at the collar level (over the apron) were 16.8, 11.9 and 4.5 mSv, respectively. This value was used for the eye lens dose assessment. Estimated doses are in accordance with or higher than annual dose limits for the occupational exposure. (authors)

The conversion coefficients (CC from directly measured dose area product (DAP value to effective dose (ED were calculated within the approved effective dose assessment methodology (Guidelines 2.6.1. 2944-11. The CC, Ed K , [mSv / (Gy • cm2] for newborn infants and children of 1, 5, 10 and 15 years old (main(range were calculated as 2.5 (1.8-3.2; 1.1 (0.8-1.3; 0.6 (0.4-0.7; 0.4 (0.3-0.5; and 0,22 (0,18-0,30 respectively. A special Finnish computer program PCXMC 2.0 was used for calculating the dose CC. The series of calculations were made for different values of the physical and geometrical parameters based on their real-existing range of values. The value of CC from DAP to ED were calculated for all pediatric age groups. This work included 153 pediatric interventional studies carried out in two hospitals of the city of St. Petersburg for the period of one year from the summer of 2015. The dose CC dependency from the patient’s age and parameters of the examinations were under the study. The dependence from the beam quality (filtration and tube voltage and age of the patient were found. The younger is the patient, stronger is the filtration and higher is the voltage, the higher is the CC value. The CC in the younger (newborn and older (15 years age groups are different by the factor of 10. It was shown that the changes of the geometric parameters (in the scope of their real existing range have small effect on the value of the effective dose, not exceed 30-50% allowable for radiation protection purpose. The real values of effective doses of children undergoing cardiac interventions were estimated. In severe cases, the values of ED can reach several tens of mSv.

    During the last 30 years the use of Interventional Cardiology (IC) procedures has increased significantly, mainly due to the benefits and advantages of the method that offers more accurate diagnosis and treatment along with less complications and hospitalization. However, IC procedures are based on the use of x-ray radiation, mostly localized at certain areas of patient's body and for extended periods of time. Consequently, patient may receive high radiation dose and deterministic effects, such as erythema, epilation or even dermal necrosis may be observed. Therefore, the need for reducing radiation dose is highly important. In order to achieve this, good knowledge of the dose levels delivered to the patient during IC procedures is essential since radiation effects are known to increase with dose. It is of great interest to know the point where the maximum skin dose (MSD) is noted since individual sensitivity may vary. MSDs greater than 1 Gy should be recorded. Patient dosimetry during IC procedures is a complex task since these type of procedures depend on various factors, such as complexity and severity of case, different specifications of x-ray equipment and patient's physical characteristics. Moreover, cardiologist's experience plays an important role. For these reasons, Food and Drug Administration (FDA), the International Commission on Radiological Protection (ICRP) as well as the World Health Organization (WHO), have published documents on radiation safety and ways to reduce skin injuries during IC procedures. Various methods have been proposed for measuring MSD such as the use of slow radiotherapy films, thermoluminescent detectors (TLD), scintillation detectors, Dose-Area Product (DAP) meter, as well as a combination of DAP and air kerma. A literature review on MSDs measured during IC procedures showed that doses ranged from 300 to 43000 mGy

    Terminology and Lexicography have been especially addressed to the Allied Health Sciences regarding discussion of case reports or concerning publication of scientific articles. The knowledge of Human Anatomy enables the understanding of medical terms and the refinement of Medical Terminology makes possible a better anatomicomedical communication in a highly technical level. Most of the scientific publications in both Anatomy and Medicine are found only in English and most of dictionaries or search resources available do not have specificity enough to explain anatomicomedical, terminological, or lexicographical occurrences. To design and produce a multilingual terminological dictionary (Latin-English-Portuguese-Spanish) containing a list of English anatomicomedical terms in common usage in cardiology subspecialties addressed to medical students and professionals, to other allied health sciences professionals, and to translators working in this specific field. Terms, semantical and grammatical components were selected to compose an anatomicocardiological corpus. The adequacy to the thematic terminological research requests and the translation reliability level will be settled from the terminology specificity in contrast to the semantics, as well as from a peer survey of the main terms used by national and international experts in specialized journals, Internet sites, and from text-books on Anatomy and Cardiology. The inclusion criteria will be the terms included in the English, Portuguese, and Spanish Terminologia Anatomica - the official terminology of the anatomical sciences; nonofficial technical commonly used terms which lead to terminology or translation misunderstanding often being a source of confusion. A table with a sample of the 508 most used anatomical cardiologic terms in English language peer-reviewed journals of cardiology and (pediatric and adult) thoracic surgery is shown. The working up of a multilingual terminological dictionary reduces the risk of

    Hemodynamics plays an essential role in the progression and treatment of cardiovascular disease. However, while medical imaging provides increasingly detailed anatomical information, clinicians often have limited access to hemodynamic data that may be crucial to patient risk assessment and treatment planning. Computational simulations can now provide detailed hemodynamic data to augment clinical knowledge in both adult and pediatric applications. There is a particular need for simulation tools in pediatric cardiology, due to the wide variation in anatomy and physiology in congenital heart disease patients, necessitating individualized treatment plans. Despite great strides in medical imaging, enabling extraction of flow information from magnetic resonance and ultrasound imaging, simulations offer predictive capabilities that imaging alone cannot provide. Patient specific simulations can be used for in silico testing of new surgical designs, treatment planning, device testing, and patient risk stratification. Furthermore, simulations can be performed at no direct risk to the patient. In this paper, we outline the current state of the art in methods for cardiovascular blood flow simulation and virtual surgery. We then step through pressing challenges in the field, including multiscale modeling, boundary condition selection, optimization, and uncertainty quantification. Finally, we summarize simulation results of two representative examples from pediatric cardiology: single ventricle physiology, and coronary aneurysms caused by Kawasaki disease. These examples illustrate the potential impact of computational modeling tools in the clinical setting.

    Hemodynamics plays an essential role in the progression and treatment of cardiovascular disease. This is particularly true in pediatric cardiology, due to the wide variation in anatomy observed in congenital heart disease patients. While medical imaging provides increasingly detailed anatomical information, clinicians currently have limited knowledge of important fluid mechanical parameters. Treatment decisions are therefore often made using anatomical information alone, despite the known links between fluid mechanics and disease progression. Patient-specific simulations now offer the means to provide this missing information, and, more importantly, to perform in-silico testing of new surgical designs at no risk to the patient. In this talk, we will outline the current state of the art in methods for cardiovascular blood flow simulation and virtual surgery. We will then present new methodology for coupling optimization with simulation and uncertainty quantification to customize treatments for individual patients. Finally, we will present examples in pediatric cardiology that illustrate the potential impact of these tools in the clinical setting.

    The contribution of interventional cardiology procedures to the population dose in Europe is poorly known. The estimation of the population dose from these procedures requires knowledge of both the typical dose received by patients and an estimate of the number of procedures undertaken annually. Data on the number of cardiology procedures in various European countries are available on the internet for a number of countries. However, this data set is incomplete or out of date. This paper describes the statistical analysis undertaken to estimate the number of interventional cardiology procedures in a number of European countries for 2007. Estimates of the number of procedures are given. On average, the number of cardiac catheterizations per million population is 5346, percutaneous transluminal coronary angioplasty is 1599 and 1214 stent procedures. In addition, there are an estimated 973 pacemaker insertions per million population. (authors)

    Recent studies have reported a significant increase in eye lens opacities among staff in the cardiac catheterization laboratory but indicated further studies are needed to confirm the findings. To evaluate the prevalence of opacities in eyes of cardiologists, radiographers and nurses working in interventional cardiology. The eyes of 52 staff in interventional cardiology facilities and 34 age- and sex-matched unexposed controls were screened in a cardiology conference held in Kuala Lumpur by dilated slit-lamp examination, and posterior lens changes were graded. Individual cumulative lens X-ray exposures were calculated from responses to a questionnaire in terms of workload and working practice. The prevalence of posterior lens opacities among interventional cardiologists was 53%, while in nurses and radiographers it was 45%. Corresponding relative risks were 2.6 (95% CI: 1.2-5.4) and 2.2 (95% CI: 0.98-4.9), for interventional cardiologists and support staff, respectively. This study confirms a statistically significant increase in radiation-associated posterior lens changes in the eyes of interventional cardiology staff. Copyright © 2012 S. Karger AG, Basel.

    The purpose of this work is to evaluate radiation doses to the lens of urologists during interventional procedures and to compare them with values measured during interventional radiology, cardiology and vascular surgery. The measurements were carried out in a surgical theatre using a mobile C-arm system and electronic occupational dosimeters (worn over the lead apron). Patient and staff dose measurements were collected in a sample of 34 urology interventions (nephrolithotomies). The same dosimetry system was used in other medical specialties for comparison purposes. Median and 3rd quartile values for urology procedures were: patient doses 30 and 40 Gy cm 2 ; personal dose equivalent Hp(10) over the apron (μSv/procedure): 393 and 848 (for urologists); 21 and 39 (for nurses). Median values of over apron dose per procedure for urologists resulted 18.7 times higher than those measured for radiologists and cardiologists working with proper protection (using ceiling suspended screens) in catheterisation laboratories, and 4.2 times higher than the values measured for vascular surgeons at the same hospital. Comparison with passive dosimeters worn near the eyes suggests that dosimeters worn over the apron could be a reasonable conservative estimate for ocular doses for interventional urology. Authors recommend that at least the main surgeon uses protective eyewear during interventional urology procedures. (paper)

    Background: There is a paucity of information worldwide on radiation exposure in paediatric interventional cardiology. At present Nationally established Diagnostic Reference Levels exist for adult interventional cardiology procedures in the UK but little data is available for paediatrics. In addition, interventional cardiology has been identified as one the highest contributors to medical exposure to ionising radiation and children are more radiosensitive than adults. Objective: This study sought to determine current radiation dose levels in paediatric interventional cardiology (IC) with a view to establishing local diagnostic reference levels (LDRL). Methods: Radiation dose and examination details were recorded for 354 paediatric patients examined by IC in a specialised paediatric centre in Europe. Radiation doses were recorded using a Dose Area Product meter along with examination details. Procedures were categorised as either diagnostic (A) or therapeutic (B). Data was further sub-divided into five age ranges; (1) newborn <1 year (2) 1 <5 years (3) 5 <10 years (4) 10 <15 years (5) 15 years and over. Proposed LDRL were calculated from the mean dose area product readings. Results: The mean patient age was 2.6 years (range 0.0 days–16 years) and weight was 14.9 kg (range 2.4–112 kg). LDRL for the five age groupings were calculated as 190, 421, 582, 1289 and 1776 cGycm² respectively. Conclusion: Local dose reference levels have been proposed for paediatric IC and can be used as a benchmark for other hospitals to compare against their own radiation doses

    In this work, we present clinical images of IVUS and OCT in the evaluation of pharmacological stent endothelization. These preliminary imaging results are analyzed and compared in order to determine the ability of these technologies to visualize relevant intravascular features of interest in interventional cardiology. The results enable to compare the performance of both techniques and to evaluate their potential for clinical purposes.

    The number of cardiology interventional procedures has significantly increased recently. This is due to the reliability of the diagnostic equipment to diagnose many heart diseases. In the procedures the x-ray used results in increasing radiation doses to the staff. The cardiologists and other staff member in interventional cardiology are usually working close to the area under examination and receive the dose primarily as well as from scattered radiation from the patients. In this study three electronic personal dosimeters (EPDs) were used to measured personal equivalent dose Hp (10) for assessment staff doses were monitoring during interventional cardiology procedure, totally in (100) procedures were performed in two clinical. The procedures was collect in two main hospitals in Khartoum State, the staff workers include cardiologists, technologists and nurses. The EPDs were used by each worker at the two cardiology centers, was one worn under a protective apron attach to chest. The annual doses received by 6 cardiologists, 6 nurses and 2 technologists at the sudan heart center were tn the range: (27.25-33.5) μSv, (3.25-3.66) μSv, (3.25-3.66) μSv, (3.23 and 3.70) μSv respectively. In the royal care hospital the annual doses received by 2 doctors, 4 nurses and 2 technologists were in the range ( 38.375 and 39.375) μSv (12.06-14.125) μSv, (8.5 and 9.25) μSv respectively, estimated for four weeks. The highest doses were received by the cardiologist followed by nurses and the x-ray technicians. The results showed that the annual doses received by the workers do not exceed 20 mSv. Recommendation on how to reduce staff doses in interventional cardiology are presented.(Author)

  12. The Information System on Occupational Exposure in Medicine, Industry and Research (ISEMIR): Interventional Cardiology

    2014-02-01

    In the last three decades, the use of image guided interventional procedures in cardiology has increased significantly, bringing great benefit to millions of patients around the world. As technology improves, the medical capabilities of these procedures continue to expand, adding further to the armamentarium for diagnosis and treatment of patients with cardiac problems. All of these procedures require health professionals (including interventional cardiologists, electrophysiologists, nurses and medical radiation technologists) to be present in the room and alongside the patient when radiation is being used, which may result in occupational exposure. While it has been long known that there is significant potential for health professionals in attendance during interventional cardiology to receive non-trivial occupational exposures, reported details have been typically limited to a few specific interventional cardiology facilities and situations. A more global perspective has been lacking, as is the availability of a systematic means for improving occupational radiation protection in interventional cardiology facilities throughout the world. In 2006, the IAEA published the Fundamental Safety Principles (IAEA Safety Standards Series No. SF-1), which sets out the fundamental safety objective and principles of protection and safety. In 2011, the IAEA published Radiation Protection and Safety of Sources: International Basic Safety Standards (IAEA Safety Standards Series No. GSR Part 3 (Interim Edition)), which sets out the requirements for meeting the fundamental safety objective and applying the principles specified in the Fundamental Safety Principles. The establishment of safety requirements and provision of guidance on occupational radiation protection is a major component of the support for radiation protection and safety provided by the IAEA to Member States. This publication was developed under the IAEA's statutory responsibility to facilitate worldwide application

    The purpose of this article is to estimate lens doses using over apron active personal dosemeters in interventional catheterisation laboratories (cardiology IC, neuroradiology IN and radiology IR) and to investigate correlations between occupational lens doses and patient doses. Active electronic personal dosemeters placed over the lead apron were used on a sample of 204 IC procedures, 274 IN and 220 IR (all performed at the same university hospital). Patient dose values (kerma area product) were also recorded to evaluate correlations with occupational doses. Operators used the ceiling-suspended screen in most cases. The median and third quartile values of equivalent dose Hp(10) per procedure measured over the apron for IC, IN and IR resulted, respectively, in 21/67, 19/44 and 24/54 μSv. Patient dose values (median/third quartile) were 75/128, 83/176 and 61/159 Gy cm 2 , respectively. The median ratios for dosemeters worn over the apron by operators ( protected by the ceiling-suspended screen) and patient doses were 0.36; 0.21 and 0.46 μSv Gy -1 cm -2 , respectively. With the conservative approach used (lens doses estimated from the over apron chest dosemeter) we came to the conclusion that more than 800 procedures y -1 and per operator were necessary to reach the new lens dose limit for the three interventional specialties.

    Workers involved in interventional cardiology procedures receive high eye lens doses if radiation protection tools are not properly utilized. Currently, there is no suitable method for routine measurement of eye dose. In Thailand, the eye lens equivalent doses in terms of Hp(3) of the interventional cardiologists, nurses, and radiographers participating in interventional cardiology procedures have been measured at 12 centers since 2015 in the pilot study. The optically stimulated luminescence (OSL) dosimeter was used for measurement of the occupational exposure and the eye lens dose of 42 interventional cardiology personnel at King Chulalongkorn Memorial Hospital as one of the pilot centers. For all personnel, it is recommended that a first In Light OSL badge is placed at waist level and under the lead apron for determination of Hp(10); a second badge is placed at the collar for determination of Hp(0.07) and estimation of Hp(3). Nano Dots OSL dosimeter has been used as an eye lens dosimeter for 16 interventional cardiology personnel, both with and without lead-glass eyewear. The mean effective dose at the body, equivalent dose at the collar, and estimated eye lens dose were 0.801, 5.88, and 5.70 mSv per year, respectively. The mean eye lens dose measured by the Nano Dots dosimeter was 8.059 mSv per year on the left eye and 3.552 mSv per year on the right eye. Two of 16 interventional cardiologists received annual eye lens doses on the left side without lead glass that were higher than 20 mSv per year, the new eye lens dose limit as recommended by ICRP with the risk of eye lens opacity and cataract.

    This study aimed to evaluate paediatric radiation doses in a dedicated cardiology hospital, with the objective of characterising patterns in dose variation. The ultimate purpose was to define Local (Institutional) Diagnostic Reference Levels (LDRLs) for different types of paediatric cardiac interventional procedures (IC), according to patient age. From a total of 710 cases performed during three consecutive years, by operators with more than 15 years of experience, the age was noted in only 477 IC procedures. The median values obtained for Fluoroscopy Time (FT), Number of Frames (N) and Kerma Area Product (P KA ) by age range were 5.8 min, 1322 and 2.0 Gy.cm 2 for definition of LDRLs presents challenges mainly due to the multiple clinical and technical factors affecting the outcome. On the other hand the lack of paediatric IC DRLs makes the identification of good practices more difficult. A consensus is needed on IC procedures nomenclature and grouping in order to allow a common assessment and comparison of doses. Copyright © 2018 Associazione Italiana di Fisica Medica.

    Cardiovascular medicine is one of the specialties that has relied most heavily on evidence from randomized clinical trials in determining best practice for the management of common disease conditions. When comparing treatment approaches, trials incorporating random allocation are the most appropriate method for protecting against treatment allocation bias. In order to protect against performance and ascertainment bias, trial designs including placebo control are preferable where feasible. In contrast to testing of medicines, treatments based on procedures or use of medical devices are more challenging to assess, as sham procedures are necessary to facilitate blinding of participants. However, in many cases, ethical concerns exist, as individual patients allocated to sham procedure are exposed only to risk without potential for benefit. Accordingly, the potential benefits to the general patient population must be carefully weighed against the risks of the exposed individuals. For this reason, trial design and study conduct are critically important to ensure that the investigation has the best chance of answering the study question at hand. In the current manuscript, we aim to review issues relating to the conduct of sham-controlled trials and discuss a number of recent examples in the field of interventional cardiology.

    The relationship between patient dose (PD) and occupational dose (OD) is not easily predictable in interventional radiology installations due to a large number of factors which can modify the occupational risk (OR). In the present work an analysis is made of the four main aspects which influence OR, namely, x-ray beam used, radiation protection (RP) tools available (aprons, thyroid protectors, gloves, screens, etc) and their regular use, type and number of procedures performed (diagnostic or therapeutic, complexity level, etc), and RP training level of the specialists. High filtration x-ray beams can entail a decrease of 20% in OD. A regular use of ceiling mounted faceplates can involve dose savings up to 65%. Mean values of dose per procedure for interventional radiologists are something greater (about 15%) than those recorded for cardiologists, except for the dosimeters placed on left forearm and shoulder. The ratio between OD and PD range around 100 μSv/1,000 cGy.cm 2 . The influence of the staff RP training level on OD is difficult to assess. In the IC Service from the Madrid San Carlos University Hospital (SCUH), PD have been reduced in above 30% and OD in a factor of 3, after running some training programmes. (author)

  19. Mapping intravascular ultrasound controversies in interventional cardiology practice.

    Directory of Open Access Journals (Sweden)

    David Maresca

    Full Text Available Intravascular ultrasound is a catheter-based imaging modality that was developed to investigate the condition of coronary arteries and assess the vulnerability of coronary atherosclerotic plaques in particular. Since its introduction in the clinic 20 years ago, use of intravascular ultrasound innovation has been relatively limited. Intravascular ultrasound remains a niche technology; its clinical practice did not vastly expand, except in Japan, where intravascular ultrasound is an appraised tool for guiding percutaneous coronary interventions. In this qualitative research study, we follow scholarship on the sociology of innovation in exploring both the current adoption practices and perspectives on the future of intravascular ultrasound. We conducted a survey of biomedical experts with experience in the technology, the practice, and the commercialization of intravascular ultrasound. The collected information enabled us to map intravascular ultrasound controversies as well as to outline the dynamics of the international network of experts that generates intravascular ultrasound innovations and uses intravascular ultrasound technologies. While the technology is praised for its capacity to measure coronary atherosclerotic plaque morphology and is steadily used in clinical research, the lack of demonstrated benefits of intravascular ultrasound guided coronary interventions emerges as the strongest factor that prevents its expansion. Furthermore, most of the controversies identified were external to intravascular ultrasound technology itself, meaning that decision making at the industrial, financial and regulatory levels are likely to determine the future of intravascular ultrasound. In light of opinions from the responding experts', a wider adoption of intravascular ultrasound as a stand-alone imaging modality seems rather uncertain, but the appeal for this technology may be renewed by improving image quality and through combination with

    The lens of the eye is one of the radiosensitive tissues of the human body; if exposed to ionizing radiation can develop radiation-induced cataract at early ages. This study was held in Greece and included 44 Interventional Cardiologists (ICs) and an unexposed to radiation control group of 22 persons. Of the note, 26 ICs and the unexposed individuals underwent special eye examinations. The detected lens opacities were classified according to LOCS III protocol. Additionally, the lens doses of the ICs were measured using eye lens dosemeters. The mean dose to the lenses of the ICs per month was 0.83 ± 0.59 mSv for the left and 0.35 ± 0.38 mSv for the right eye, while the annual doses ranged between 0.7 and 11 mSv. Regarding the lens opacities, the two groups did not differ significantly in the prevalence of either nuclear or cortical lens opacities, whereas four ICs were detected with early stage subcapsular sclerosis. Though no statistically difference was observed in the cohort, the measured doses indicate that the eye doses received from the ICs can be significant. To minimize the radiation-induced risk at the eye lenses, the use of protective equipment and appropriate training on this issue is highly recommended. (authors)

    2013-01-01

    Background: It is not known whether leaded glass goggles with 0.25 mm Pb equivalency, used in interventional cardiology procedures, attenuate radiation below the levels established by the latest recommendation of the International Commission on Radiological Protection (ICRP). Aim: To assess if the degree of attenuation of the secondary ionizing radiation achieved by the use of 0.25 mm Pb leaded glass goggles, in occupationally exposed workers in interventional cardiology procedures, meets the latest ICRP recommendations. Material and Methods : A prospective investigation was carried out to compare the eye exposure to secondary ionizing radiation received by occupationally exposed personnel in a 9 months period. A set of two thermo luminescent dosimeters was arranged in the front and back of leaded glass goggles in a cohort of seven members of an interventional cardiology service, exposed to 1057 consecutive procedures. Results:The monthly dose equivalent measurement performed in front of the goggles ranged between 1.1 and 6.5 mSv,for paramedics and interventional cardiologists. The radiation measured in the back of the glass varied between 0.66 and 2.75 mSv,respectively.The degree of attenuation of the dose at eye level ranged from 40% to 57.7%,respectively. The projected annual exposure would reach 33 mSv for the interventional cardiologist. Conclusions: With a similar load of work and wearing 0.25 mm Pb equivalent glass goggles, interventional cardiologists will exceed the crystalline equivalent dose limit recommended by the ICRP (20 mSv/year averaged over the past 5 years)

    Purpose: In this study the use of flat detector computed tomography (FD-CT) in the catheterization of patients with congenital heart disease was evaluated. Application reports were created for various issues based on the achieved image quality in diverse anatomical regions. Materials and Methods: FD-CT was applied in 176 cases during catheterization between January 2010 and April 2012. A five-point Likert scale ('essential' to 'misleading') was used to evaluate image quality. All cases were analyzed retrospectively and application reports for the visualization of the aorta, pulmonary arteries, pulmonary veins, semilunar valves, cavopulmonary connections and atrial baffles were generated. Contrast dye consumption and radiation dose were evaluated. Results: During the observation period FD-CT was applied in all 176 cases. The mean patient age was 7.0 years (0.01 - 42.53 years). The clinical value of FD-CT was rated superior to conventional angiography in 96.6 % of the cases and was never rated as 'misleading'. FD-CT was rated 'essential' in 3.4 % of all cases, 'very useful' in 77.3 % of all cases, 'useful' in 15.9 % of all cases and 'not useful' in 3.4 % of all cases. The mean dose-area product was 99 μGym 2 (19.3 - 1276.6 μGym 2 ), and the used contrast dye was 1.76 ml/kg (0.9 - 5 ml/kg). Application reports for the visualization of different anatomical regions are demonstrated. Conclusion: FD-CT is a new and auxiliary procedure in diagnostic and interventional catheterization of patients with congenital heart disease. Particularly extracardiac structures can be displayed in three-dimensional high resolution and be used for diagnosis, surgical planning and 3 D navigation. (orig.)

    The objective of this article is to present initial occupational dose values using digital active personal dosimeters for medical staff during adult interventional cardiology procedures in a public hospital in Chile. Personal dose equivalent Hp(10) over the lead apron of physician, nurse and radiographer were measured during 59 procedures. Mean values of occupational dose Hp(10) per procedure were 47.6, 6.2 and 4.3 μSv for physician, nurse and radiographer, respectively. If no protective tools are used, physician dose can exceed the new eye lens dose limit.

    Many patients who receive medical interventional cardiology procedures at a tertiary hospital live outside the metropolitan area and may experience fragmentation in care, less emotional support by family members, inaccurate and delayed communication, and lack of educational follow-up on discharge from the hospital. A clinical pathway titled "Heart Health Care Patterns" was developed to link acute phase, recovery phase, rehabilitation phase, and enhancement/maintenance phase. The 12-month clinical pathway combines Gordon's Functional Health Patterns and the Omaha System developed by the Omaha Visiting Nurse Association. The rating scale for outcomes assesses the patient at different phases to provide objective data and information throughout the year.

    After a discussion of several publications about patient dosimetry in interventional cardiology, the author recalls that the in vivo assessment of the dose received by some organs is uneasy because invasive. Therefore, the assessment requires the use of physical or mathematical dosimetric phantoms which simulate patient morphology as well as the incident photon attenuation phenomenon. He evokes some characteristics and applications of these phantoms. He outlines the different sources and origins of the dose received by the patient, and discusses results obtained by collecting data from 177 patients submitted to diagnosis or therapeutic procedures

    In recent years, the number of interventional cardiology procedures is increasing. However, due to the long time of fluoroscopy in these procedures, care teams can receive high doses of radiation. The radiation scattered by the patient is not uniform, and their assessment is of utmost importance. This study aimed to estimate and map the kerma rate in the air at the time of the gonads, in an interventional cardiology room, seeking to optimize the dose absorbed by individuals occupationally exposed to ionizing radiation. For data collection, the room was divided into quadrants of 1m 2 , totaling 40 collection points. The simulator was positioned so that its entry surface was located in the interventional reference point. Were chosen the conditions that simulate angiography and angioplasty procedures performed in the service. The data were obtained for height of 1 meter, gonad region. The results obtained for kerma rates in air, in quadrants, show that higher measured values was in the vicinity of the X-ray tube. Has been found that the medical staff are more exposed, because of its location during the procedure, around the table. The law of the inverse square distance of the farthest points of the X-ray tube were verified

    In interventional cardiac procedures, staff operates near the patient in a non-uniformly scattered radiation field. Consequently, workers may receive, over a period of time, relatively high radiation doses. The measurement of individual doses to personnel becomes critical due to the use of protective devices and, as a consequence of the large number of methods proposed to assess the effective dose, In this study, staff doses were measured in two cardiac centers: Ahmed Gasim Hospital and Cardiac Center, Khartoum. The objective was to measure personal dose equivalent and accordingly estimate the effective dose which is received by staff in interventional cardiology. Measurements were performed using electronic personal dosimeters (EPDs) worn over lead apron during the examination and were read immediately following each examination. A total number of 40 radiation worker were monitored for a period of two weeks. The highest doses received by the cardiologist followed by nurses and then X-ray technicians. Staff received mean effective doses that ranged from 24 to 110 μSv estimated for four weeks. Recommendations on how to reduce staff doses in interventional cardiology are presented. (Author)

    Risk aversion is a potential unintended consequence of health care public reporting. In Part 1 of this review, four possible consequences of this phenomenon are discussed, including the denial of interventions to some high-risk patients, stifling of innovation, appropriate avoidance of futile interventions, and better matching of high-risk patients to more capable providers. We also summarize relevant observational clinical reports and survey results from cardiovascular medicine and surgery, the two specialties from which almost all risk aversion observations have been derived. Although these demonstrate that risk aversion does occur, the empirical data are much more consistent and compelling for interventional cardiology than for cardiac surgery.

    The objective of this paper is to identify the effects of the ceiling suspended screen position to the scatter radiation levels in the interventional cardiology. The scatter radiation in terms of ambient dose equivalent H * (10) was measured for various positions of protective screen in the positions of the first operator, nurse and radiographer, at elevations 100-190 cm and in four different angulations of the x-ray tube. To assess the effectiveness of the protective screen, the scattered dose was also measured in the absence of any protection in all four angulations and elevations. To simulate real clinical situation the measurements were performed in the presence of 30 cm PMMA phantom using standard clinical protocol. The utility of protective screen varied for different positions and angulations. Scatter radiation levels varied in the range 70 - 3400 μSv/h for the first operator, 140 - 3200 μSv/h for the nurse and 50 - 560 μSv/h for radiographer. Ceiling suspended screens can provide a substantial level of protection (up to factor 18) in interventional cardiology, but they have to be properly managed and positioned to achieve sufficient level of protection. The guidance for optimal protection is provided in the paper.(author)

    Entrance surface air kerma (ESAK) values and image quality parameters were measured and compared for two biplane angiography x-ray systems dedicated to paediatric interventional cardiology, one equipped with image intensifiers (II) and the other one with dynamic flat detectors (FDs). Polymethyl methacrylate phantoms of different thicknesses, ranging from 8 to 16 cm, and a Leeds TOR 18-FG test object were used. The parameters of the image quality evaluated were noise, signal-difference-to-noise ratio (SdNR), high contrast spatial resolution (HCSR) and three figures of merit combining entrance doses and signal-to-noise ratios or HCSR. The comparisons showed a better behaviour of the II-based system in the low contrast region over the whole interval of thicknesses. The FD-based system showed a better performance in HCSR. The FD system evaluated would need around two times more dose than the II system evaluated to reach a given value of SdNR; moreover, a better spatial resolution was measured (and perceived in conventional monitors) for the system equipped with flat detectors. According to the results of this paper, the use of dynamic FD systems does not lead to an automatic reduction in ESAK or to an automatic improvement in image quality by comparison with II systems. Any improvement also depends on the setting of the x-ray systems and it should still be possible to refine these settings for some of the dynamic FDs used in paediatric cardiology.

    The aim of this work is to assess level of radiation dose to patients in interventional cardiology procedures in three large Serbian hospitals and to investigate possibility for setting of trigger levels if dose quantities exceed certain levels. Three dedicated interventional cardiology laboratories were included in the survey. Information on annual workload was estimated based on number of coronary angiography (CA) procedures and percutaneous coronary interventions (PCI). Patients doses were assessed in terms of air kerma area product (PKA) and air kerma in international reference point (KIRP). Results were compared with internationally proposed Diagnostic Reference Levels (DRL) and similar surveys results. Average total annual number of procedures was 820, 1100 and 2500 in three hospitals, respectively, while total number of dose measurements was 337. All three centers reported PKA values higher than 100 Gy·cm 2 and even values above 200 Gy·cm 2 , corresponding to 42% and 16% of all measurements. Measured KIRP value higher than 5 Gy was reported in one center, indicating that skin doses associated possibility of skin injuries were observed. PKA mean hospital values for CA ranged from 33 to 78 Gy·cm 2 and for PCI from 73 to 113 Gy·cm 2 , while associated vales for KIRP were: 0.45-1.2 Gy and 1.1-1.8 Gy, respectively. Comparison of obtained results with international DRL indicated that significant number of procedures is not optimally performed as in some centers more than a half of patients receive doses above DRL. The presented results are valuable input for dose optimization strategies and increased awareness related to importance of dose management. With respect to high dose values, risk for stochastic effects and tissue reactions, dose management methods were proposed. (Author)

    The purpose of this paper is to test the appropriateness of OSL and electronic dosemeters to estimate eye lens doses at interventional cardiology environment. Using TLD as reference detectors, personal dose equivalent was measured in phantoms and during clinical procedures. For phantom measurements, OSL dose values resulted in an average difference of 215 % vs. TLD. Tests carried out with other electronic dosemeters revealed differences up to ±20 % versus TLD. With dosemeters positioned outside the goggles and when TLD doses were >20 μSv, the average difference OSL vs. TLD was 29 %. Eye lens doses of almost 700 μSv per procedure were measured in two cases out of a sample of 33 measurements in individual clinical procedures, thus showing the risk of high exposure to the lenses of the eye when protection rules are not followed. The differences found between OSL and TLD are acceptable for the purpose and range of doses measured in the survey (authors)

    Within the ORAMED project (Optimization of Radiation Protection of Medical Staff) a coordinated measurement program for occupationally exposed medical staff was performed in different hospitals in Europe ( (www.oramed-fp7.eu)). The main objective was to obtain a set of standardized data on extremity and eye lens doses for staff involved in interventional radiology and cardiology and to optimize radiation protection. Special attention was given to the measurement of the doses to the eye lenses. In this paper an overview will be given of the measured eye lens doses and the main influence factors for these doses. The measured eye lens doses are extrapolated to annual doses. The extrapolations showed that monitoring of the eye lens should be performed on routine basis.

    The eye lens annual dose limit for exposed personnel to ionizing radiation has recently been revised by the ICRP—International Commission on Radiological Protection and the proposed new limit has been accepted by European legislation through the Council Directive 2013/59/EURATOM 2013.Among medical exposed personnel, the staff performing interventional cardiology are usually affected by relevant doses. For this reason a survey, employing dosemeters characterized in terms of H p (3), was performed in order to get the order of magnitude of the doses received by the eye lens, at least as a first guess.The survey showed that the annual dose limit can easily be reached if a proper radiation protection approach is not implemented.

    Cardiologist and other staff members receive high doses of scattered radiation. Cases of radiation-induced cataract among cardiology professionals have been reported in studies, estimates for the dose to eye lens ranged from 450 to 900 mSv per year (without ceiling suspended screen), over several years. Recent surveys regarding high prevalence of lens changes likely induced by radiation exposure suggest an urgent need for improved radiation safety and training, use of eye protection during catheterization procedures, and improved occupational dosimetry. In view of the evidence of radiation injuries, the ICRP recommends limiting the radiation dose to the lens to 20 mSv per year for occupational exposure. A system for optimizing the radiation exposure is the measurement of entrance surface air kerma (K a,e ) and kerma-area product (P KA ) for patient and scattered dose or dose rate at the position for the staff, under clinical working conditions using phantoms and defined technical factors. Correlating K a,e and P KA with the scatter dose, applying the attenuation factors protective devices can enable estimation of the lens doses for operators. The purpose of this work is: to study the possibility of establishing a procedure which is useful for scientific societies and the regulatory authority in the prevention and control of IOE dose and to control and improve the quality of procedures in interventional cardiology as an initiative to raise awareness and optimization of radiological protection. Measurements were taken in different cardiac laboratories. Clinical working conditions were reproduced during the experiments for the different hemodynamic angiographic projections and operating modes used in fluoroscopy and cine. A first K a,e rate reference proposal for the characterization of angiography for the different acquisition modes were 16; 35; 40 and 220 (mGy/min), respectively.

    Full text: Purpose: To evaluate patient doses in Interventional Radiology (IR) and Cardiology (IC) procedures in Algeria, within the framework of an International Atomic Energy Agency (IAEA) regional project on radiation protection of patients and medical exposure control (RAF 9033). Materials and Methods: Three public hospitals (CHU Bab el Oued, CHU Parnet and CHU Mustapha) and one specialised Cardiology Service (Clinique Maouche) were chosen for the study. For Maximum Skin Dose (MSD) evaluation, gafchromic films XR type R were used, placed on patient's back before the procedure. The Dose Area Product (DAP) and MSD were measured in 57 IR and IC procedures, either diagnostic or therapeutic. Results: The results revealed large variations in MSD (0.06-3.3 Gy) and DAP (5.5-332 mGycm 2 ). Mean MSD was 0.227 Gy in cerebral angiography, 0.202 Gy in coronary angiography, 1.162 Gy in Percutaneus Transluminal Coronary Angioplasty (PTCA) and 0.128 in abdominal angiography. The correlation of DAP and MSD was significant (r = 0.7). The correlation was DAP and fluoroscopy time was also significant (r = 0.8). Conclusion: The highest MSD values were found in PTCA which is a therapeutic procedure. Two PTCAs out of the 57 procedures measured in total had MSD over the threshold of 2 Gy for deterministic effects (MSD 1 = 3.0 Gy and MSD 2 3.3 Gy). The large variations in MSD reveal the need to continuously monitor patient doses in IR and IC procedures with special emphasis in PTCA procedure. (author)

    A hybrid strategy, firstly performed in the 1990s, is a combination of tools available only in the catheterization laboratory with those available only in the operating room in order to minimize surgical morbidity and face with any cardiovascular lesion. The continuous evolution of stent technology along with the adoption of minimally invasive surgical approaches, make hybrid approaches an attractive alternative to standard surgical or transcatheter techniques for any given set of cardiovascular lesions. Examples include hybrid coronary revascularization, when an open surgical anastomosis of the left internal mammary artery to the left anterior descending coronary artery is performed along with stent implantation in non-left anterior descending coronary vessels, open heart valve surgery combined with percutaneous coronary interventions to coronary lesions, hybrid aortic arch debranching combined with endovascular grafting for thoracic aortic aneurysms, hybrid endocardial and epicardial atrial fibrillation procedures, and carotid artery stenting along with coronary artery bypass grafting. The cornerstone of success for all of these methods is the productive collaboration between cardiac surgeons and interventional cardiologists. The indications and patient selection of these procedures are still to be defined. However, high-risk patients have already been shown to benefit from hybrid approaches.

    Interventional Cardiology is one of the specialties in which patients are submitted to the greatest radiation doses with x ray systems used for diagnostic purposes and then, it is also a specialty of high occupational radiation risk. In the last years, several cases of radiation induced lesions produced on patients derived of new complex interventional procedures have been described. As consequence, different rules for avoiding this kind of incidents have been recommended by International Organisations and regulatory Bodies. Nevertheless it has been devoted relatively few attention to the evaluation of the occupational risks that inevitably are also high in these facilities. In this work, some cases of radioinduced skin lesions produced on patients submitted to cardiac ablation procedures are described. Radiological protection considerations of interest for the regulatory Bodies are made, that permit to minimize the probability of these incidents, in what to the X-rays equipment is referred as well as to the operation procedures and level of radiation protection training of the medical specialists.

    A study of peak skin doses (PSDs) during neuroradiology and cardiology interventional procedures has been carried out using Gafchromic XR-RV2 film. Use of mosaics made from squares held in cling film has allowed doses to the head to be mapped successfully. The displayed cumulative air kerma (CAK) has been calibrated in terms of cumulative entrance surface dose (CESD) and results indicate that this can provide a reliable indicator of the PSD in neuroradiology. Results linking PSD to CESD for interventional cardiology were variable, but CAK is still considered to provide the best option for use as an indicator of potential radiation-induced effects. A CESD exceeding 3 Gy is considered a suitable action level for triggering follow-up of patients in neuroradiology and cardiology for possible skin effects. Application of dose action levels defined in this way would affect 8% of neurological embolisation procedures and 5% of cardiology ablation and multiple stent procedures at the hospitals where the investigations were carried out. A close relationship was observed between CESD and dose-area product (DAP) for particular types of procedure, and DAPs of 200-300 Gy cm 2 could be used as trigger levels where CAK readings were not available. The DAP value would depend on the mean field size and would need to be determined for each application.

    Various studies address discrepancies between guideline recommendations for coronary angiographies and clinical practice. While the issue of the appropriateness of recurrent angiographies was studied focusing on the role of the cardiologist, little is known about individual patients' histories and the associated radiation exposures. We analyzed all patients with coronary artery disease (CAD) in an academic teaching practice who underwent at least one angiography with or without intervention between 2004 and 2009. All performed angiographies in these patients were analyzed and rated by three physicians for appropriateness levels according to cardiology guidelines. Typical exposure data from the medical literature were used to estimate individual radiation exposure. In the cohort of 147 patients, a total of 441 procedures were analyzed: between 1981 and 2009, three procedures were performed per patient (range 1-19) on average. Appropriateness ratings were 'high/intermediate' in 71 %, 'low/no' in 27.6 % and data were insufficient for ratings in 1.4 %. Procedures with 'low/no' ratings were associated with potentially avoidable exposures of up to 186 mSv for single patients. Using retrospective data, we exemplify the potential benefit of guideline adherence to decrease patients' radiation exposures. (orig.)

    The main aim of the Work Package 1 (WP1) of the ORAMED project, Collaborative Project (2008–2011), supported by the European Commission within its 7th Framework Programme, was to obtain a set of standardized data on extremity and eye lens doses for staff in interventional radiology and cardiology (IR/IC) workplaces and to recommend a series of guidelines on radiation protection in order to both guarantee and optimize staff protection. Within the project, coordinated measurements were performed in 34 hospitals in 6 European countries. Furthermore, simulations of the most representative workplaces in IR and IC were performed to determine the main parameters that influence the extremity and eye lens doses. The work presented in this paper shows the recommendations that were formulated by the results obtained from both measurements and simulations. The presented guidelines are directed to operators, assistant personnel, radiation protection officers and medical physics experts. They concern radiation protection issues, such as the use of room protective equipment, as well as the positioning of the extremity and eye lens dosemeters for routine monitoring.

    Objective The study aimed to characterise the factors related to the X-ray dose delivered to the patient's skin during interventional cardiology procedures. Methods We studied 177 coronary angiographies (CAs) and/or percutaneous transluminal coronary angioplasties (PTCAs) carried out in a French clinic on the same radiography table. The clinical and therapeutic characteristics, and the technical parameters of the procedures, were collected. The dose area product (DAP) and the maximum skin dose (MSD) were measured by an ionisation chamber (Diamentor; Philips, Amsterdam, The Netherlands) and radiosensitive film (Gafchromic; International Specialty Products Advanced Materials Group, Wayne, NJ). Multivariate analyses were used to assess the effects of the factors of interest on dose. Results The mean MSD and DAP were respectively 389 mGy and 65 Gy cm−2 for CAs, and 916 mGy and 69 Gy cm−2 for PTCAs. For 8% of the procedures, the MSD exceeded 2 Gy. Although a linear relationship between the MSD and the DAP was observed for CAs (r=0.93), a simple extrapolation of such a model to PTCAs would lead to an inadequate assessment of the risk, especially for the highest dose values. For PTCAs, the body mass index, the therapeutic complexity, the fluoroscopy time and the number of cine frames were independent explanatory factors of the MSD, whoever the practitioner was. Moreover, the effect of technical factors such as collimation, cinematography settings and X-ray tube orientations on the DAP was shown. Conclusion Optimising the technical options for interventional procedures and training staff on radiation protection might notably reduce the dose and ultimately avoid patient skin lesions.

Main adverse cardio-cerebral events (MACCE were associated with the history of coronary artery bypass grafting (OR = 0.08; 95% CI 0.01-0.62; p = 0.016, PCI (OR = 1.66; 95 % CI 1.06-2.62; p = 0.028, SYNTAX score (OR = 1.07; 95% CI 1.04-1.09; p <0.001, success of PCI (OR = 0.33; 95% CI 0.13-0.82; p = 0.017.Conclusion. PCI is a safe and effective procedure for treatment of coronary heart disease, which results in low MACCE and mortality rates.

  8. Evaluation of patients skin dose undergoing interventional cardiology procedure using radiochromic films

    In interventional cardiology (IC), coronary angiography (CA) and percutaneous transluminal coronary angioplasty (PTCA) procedures are the most frequent ones. Since the 1990s, the number of IC procedures has increased rapidly. It is also known that these procedures are associated with high radiation doses due to long fluoroscopy time (FT) and large number of cine-frames (CF) acquired to document the procedure. Mapping skin doses in IC is useful to find the probability of skin injuries, to detect areas of overlapping field, and to get a permanent record of the most exposed areas of skin. The purpose of this study was to estimate the maximum skin dose (MSD) in patients undergoing CA and PTCA, and to compare these values with the reference levels proposed in the literature. Patients' dose measurements were carried out on a sample of 38 patients at the hemodynamic department, in four local hospitals in Rio de Janeiro, Brazil, using Gafchromic XR-RV2 films. In PTCA procedures, the median and third quartile values of MSD were estimated at 2.5 and 5.3 Gy, respectively. For the CA procedures, the median and third quartile values of MSD were estimated at 0.5 and 0.7 Gy, respectively. In this paper, we used the Pearson's correlation coefficient (r), and we found a fairly strong correlation between FT and MSD (r=0.8334, p<0.0001), for CA procedures. The 1 Gy threshold for deterministic effects was exceeded in nine patients. The use of Gafchromic XR-RV2 films was shown to be an effective method to measure MSD and the dose distribution map. The method is effective to identify the distribution of radiation fields, thus allowing the follow-up of the patient to investigate the appearance of skin injuries. (author)

    Our aim was to report on a survey initiated by the European Association of Percutaneous Cardiovascular Interventions (EAPCI) collecting the opinion of the cardiology community on the invasive management of acute coronary syndrome (ACS), before and after the MATRIX trial presentation at the American College of Cardiology (ACC) 2015 Scientific Sessions. A web-based survey was distributed to all individuals registered on the EuroIntervention mailing list (n=15,200). A total of 572 and 763 physicians responded to the pre- and post-ACC survey, respectively. The radial approach emerged as the preferable access site for ACS patients undergoing invasive management with roughly every other responder interpreting the evidence for mortality benefit as definitive and calling for a guidelines upgrade to class I. The most frequently preferred anticoagulant in ACS patients remains unfractionated heparin (UFH), due to higher costs and greater perceived thrombotic risks associated with bivalirudin. However, more than a quarter of participants declared the use of bivalirudin would increase after MATRIX. The MATRIX trial reinforced the evidence for a causal association between bleeding and mortality and triggered consensus on the superiority of the radial versus femoral approach. The belief that bivalirudin mitigates bleeding risk is common, but UFH still remains the preferred anticoagulant based on lower costs and thrombotic risks.

    The purpose of this article is to present the results of connecting the interventional radiology and cardiology laboratories of five university hospitals to a unique server using an automatic patient dose registry system (Dose On Line for Interventional Radiology, DOLIR) developed in-house, and to evaluate its feasibility more than a year after its introduction. The system receives and stores demographic and dosimetric parameters included in the MPPS DICOM objects sent by the modalities to a database. A web service provides a graphical interface to analyse the information received. During 2013, the system processed 10 788 procedures (6874 cardiac, 2906 vascular and 1008 neuro interventional). The percentages of patients requiring clinical follow-up due to potential tissue reactions before and after the use of DOLIR are presented. The system allowed users to verify in real-time, if diagnostic (or interventional) reference levels are fulfilled. (authors)

    Full text: Despite of very fast developments in the field of Interventional Cardiology, the level of doses received by medical staff is still substantial and therefore must be routinely controlled. The annual dose limits established by International Commission on Radiological Protection are monitored by the personal dosimeters worn under the lead apron. In this method the information about doses on uncovered body parts can be only approximated. Values obtained by means of ring or wrist dosimetry are also insufficient to provide basis for conclusions on the extremities doses received by medical staff. The main purpose of this study was to investigate radiation doses absorbed for eye-lenses and extremities to personnel participating in cardiac procedures. The doses were measured using highly sensitive thermoluminescent dosimeters (LiF: Mg, Cu, P), calibrated in Secondary Standard Dosimetry Laboratory for X-ray beam typical of cardiac procedures. TLDs were placed in three locations: in a special band on eyebrow ridge, on a left ankle and on a left hand (finger's ring). Considerable amount of detectors used allowed determining the actual distribution of doses. Mean equivalent doses per procedure for Coronary Angiography (CAG) and Coronary Angiography with Percutaneous Transluminal Coronary Angioplasty (CAG+PTCA) were investigated. For CAG these values amounted to: on left eyebrow ridge from 80 μSv to 140 μSv, on right eyebrow ridge from 30 μSv to 75 μSv, on ankle from 80 μSv to 110 μSv and on hand from 190 μSv to 240 μSv, respectively. For CAG+PTCA the observed levels were: on left eyebrow ridge from 170 μSv to 240 μSv, on right eyebrow ridge from 60 μSv to 160 μSv, on ankle from 180 μSv to 270 μSv and on hand from 410 μSv to 590 μSv, respectively. The wild range of doses for both eyebrow ridges was especially visible and depend on operation position with respect to X-ray tube. The eye-lens doses will be measured using a Randoman anthropomorphic phantom

    An intensive measurement campaign was launched in different hospitals in Europe within work package 1 of the ORAMED project (Optimization of RAdiation protection for MEDical staff). Its main objective was to obtain a set of standardized data on extremity and eye lens doses for staff in interventional radiology (IR) and cardiology (IC) and to optimize staff protection. The monitored procedures were divided in three main categories: cardiac, general angiography and endoscopic retrograde cholangio-pancreatography(ERCP) procedures. Using a common measurement protocol, information such as the protective equipment used (lead table curtain, transparent lead glass ceiling screen, patient shielding, whole body shielding or special cabin etc.) as well as Kerma Area Product (KAP) values and access of the catheter were recorded. This study was performed with a final database of more than 1300 procedures performed in 34 European hospitals. Its objectives were firstly to determine if the measured extremity doses could be correlated to the KAP values; secondly to check if the doses to the eyes could be linked to the doses to the hands (finger or wrist positions) and finally if the doses to the fingers could be estimated based on the doses to the wrists. General correlations were very difficult to find and their strength was mostly influenced by three main parameters: the X-ray tube configuration, the room collective radioprotective equipment and the access of the catheter. The KAP value can provide a simple mean to estimate the extremity doses of the operator given that it is assessed correctly for the operator when he is actually using the X-ray tube. Moreover, this study showed that the doses to the left finger are strongly correlated to the doses to the left wrist when no ceiling shield is used. It is also possible to estimate the doses to the eyes given the doses to the left finger or left wrist but the X-ray tube configuration and the access have to be considered. The annual

    Workers involved in interventional cardiology procedures receive high eye lens dose if protection is not used. Currently, there is no suitable method for routine use for the measurement of eye dose. Since most angiography machines are equipped with suitable patient dosemeters, deriving factors linking staff eye doses to the patient doses can be helpful. In this study the patient kerma-area product, cumulative dose at an interventional reference point and eye dose in terms of Hp(3) of the cardiologists, nurses and radiographers for interventional cardiology procedures have been measured. Correlations between the patient dose and the staff eye dose were obtained. The mean eye dose was 121 mSv for the first operator, 33 mSv for the second operator/nurse and 12 mSv for radiographer. Normalised eye lens doses per unit kerma-area product were 0.94 mSv Gy -1 cm -2 for the first operator, 0.33 mSv Gy -1 cm -2 for the second operator/nurse and 0.16 mSv Gy -1 cm -2 for radiographers. Statistical analysis indicated that there is a weak but significant (p < 0.01) correlation between the eye dose and the kerma-area product for all three staff categories. These values are based on a local practice and may provide useful reference for other studies for validation and for wider utilisation in assessing the eye dose using patient dose values. (authors)

    It has become challenging for cardiovascular fellows-in-training (FIT) to determine which national cardiovascular conference (NCC) to attend given the broad range of meetings and the breadth of information offered. The aim of this study was to report our own experiences of the utility and individual strengths of the NCCs and to further understand the interventional cardiology (IC) FITs' viewpoint regarding the benefits of the individual NCCs. A survey was formulated with questions and scenarios regarding topics deemed to be of highest importance for an IC-FIT. The survey emphasized experiences regarding the utility and benefits of the NCCs, time management, optimization of acquired education, and specific interests in clinical and research topics. The completely anonymous survey was sent via an email format to a total of 234, majority of IC (fourth and fifth years) and a minority of general (third year), FITs. A completed survey response was received from 131 of the fellows (56%). The results demonstrated that the IC-FITs endorsed that the small, focused sub-specialty interventional meetings vs. the large society general meetings were more beneficial in regard to the didactic education offered. In addition, the IC-FITs indicated that pre-planning for the meetings is the most beneficial approach in optimizing one's education and that the caliber of expert faculty, case-based and live-case presentations are among the most important aspects of the meetings. Interventional cardiology FITs prefer the small sub-specialty interventional meetings over the large society general NCCs in regard to the benefits of didactic learning.

    The renewal of radiological materials has contributed to reduce significantly the doses received by the personnel. The installations of low shutters and lead windows give an important potential of reduction of doses received by the physicians. For the medical and para medical personnel, a modification of working habits must lead to an important exposure reduction. To summarize, the medical and para medical personnel in cardiology has at one s disposal all the means allowing to reach the objective of dose constraints. The radiation protection optimization now depends on every concerned actor. (N.C.)

    Despite the growing number of therapeutic alternatives available as well as general reviews and treatment guidelines for the treatment of diabetes, physicians are often left without a clear pathway of therapy to follow in specific clinical contexts such as interventional cardiology. The present document proposes a consensus treatment algorithm, based both on a critical appraisal of evidence from recent clinical trials and on value judgements supported by the authors' collective clinical knowledge and experience, in an attempt to guide practitioners when choosing the most appropriate alternatives in the context of glycemic management in type 1 and 2 diabetic patients scheduled to undergo interventional cardiology procedures in a haemodynamic laboratory.

    To compare the use of a dose mapping software to Gafchromic film measurement for a simplified peak skin dose (PSD) estimation in interventional cardiology procedure. The study was conducted on a total of 40 cardiac procedures (20 complex coronary angioplasty of chronic total occlusion (CTO) and 20 coronary angiography and coronary angioplasty (CA-PTCA)) conducted between January 2014 to December 2015. PSD measurement (PSD Film ) was obtained by placing XR-RV3 Gafchromic under the patient's back for each procedure. PSD (PSD em.dose ) was computed with the software em.dose©. The calculation was performed on the dose metrics collected from the private dose report of each procedure. Two calculation methods (method A: fluoroscopic kerma equally spread on cine acquisition and B: fluoroscopic kerma is added to one air Kerma cine acquisition that contributes to the PSD) were used to calculate the fluoroscopic dose contribution as fluoroscopic data were not recorded in our interventional room. Statistical analyses were carried out to compare PSD Film and PSD em.dose . The PSD Film median (1st quartile; 3rd quartile) was 0.251(0.190;0.336)Gy for CA-PTCA and 1.453(0.767;2.011)Gy for CTO. For method-A, the PSD em.dose was 0.248(0.182;0.369)Gy for CA-PTCA and 1.601(0.892;2.178)Gy for CTO, and 0.267(0.223;0.446)Gy and 1.75 (0.912;2.584)Gy for method-B, respectively. For the two methods, the correlation between PSD Film and PSD em.dose was strong. For all cardiology procedures investigated, the mean deviation between PSD Film and PSD em.dose was 3.4±21.1% for method-A and 17.3%±23.9% for method-B. The dose mapping software is convenient to calculate peak skin dose in interventional cardiology. Copyright © 2017 Associazione Italiana di Fisica Medica. Published by Elsevier Ltd.

    Artificial intelligence and machine learning are poised to influence nearly every aspect of the human condition, and cardiology is not an exception to this trend. This paper provides a guide for clinicians on relevant aspects of artificial intelligence and machine learning, reviews selected applications of these methods in cardiology to date, and identifies how cardiovascular medicine could incorporate artificial intelligence in the future. In particular, the paper first reviews predictive modeling concepts relevant to cardiology such as feature selection and frequent pitfalls such as improper dichotomization. Second, it discusses common algorithms used in supervised learning and reviews selected applications in cardiology and related disciplines. Third, it describes the advent of deep learning and related methods collectively called unsupervised learning, provides contextual examples both in general medicine and in cardiovascular medicine, and then explains how these methods could be applied to enable precision cardiology and improve patient outcomes.

    Purpose: To present the results of a patient dose evaluation program in pediatric cardiology and propose local diagnostic reference levels (DRLs) for different types of procedure and age range, in addition to suggesting approaches to correlate patient dose values with patient weight. This study was the first conducted in Latin America for pediatric interventional cardiology under the auspices of the International Atomic Energy Agency. Methods: Over three years, the following data regarding demographic and patient dose values were collected: age, gender, weight, height, number of cine series, total number of cine frames, fluoroscopy time (FT), and two dosimetric quantities, dose-area product (DAP) and cumulative dose (CD), at the patient entrance reference point. The third quartile values for FT, DAP, CD, number of cine series, and the DAP/body weight ratio were proposed as the set of quantities to use as local DRLs. Results: Five hundred and seventeen patients were divided into four age groups. Sample sizes by age group were 120 for <1 yr; 213 for 1 to <5 yr; 82 for 5 to <10 yr; and 102 for 10 to <16 yr. The third quartile values obtained for DAP by diagnostic and therapeutic procedures and age range were 1.17 and 1.11 Gy cm{sup 2} for <1 yr; 1.74 and 1.90 Gy cm{sup 2} for 1 to <5 yr; 2.83 and 3.22 Gy cm{sup 2} for 5 to <10 yr; and 7.34 and 8.68 Gy cm{sup 2} for 10 to <16 yr, respectively. The third quartile value obtained for the DAP/body weight ratio for the full sample of procedures was 0.17 (Gy cm{sup 2}/kg) for diagnostic and therapeutic procedures. Conclusions: The data presented in this paper are an initial attempt at establishing local DRLs in pediatric interventional cardiology, from a large sample of procedures for the standard age bands used in Europe, complemented with the values of the ratio between DAP and patient weight. This permits a rough estimate of DRLs for different patient weights and the refining of these values for the age bands when there

    Growing interest in the use of drug-eluting stents (DESs) in coronary angioplasty has prompted the Healthcare Agency of the Emilia Romagna Region to draw up recommendations for their appropriate clinical use in high-risk patients. Since the adoption of any new technology necessitates economic appraisal, we analysed the resource consumption of the various types of angioplasty procedures and the impact on the budget of a cardiology department. A retrospective economic appraisal was carried out on the coronary angioplasty procedures performed in 2004 in the Department of Interventional Cardiology of Reggio Emilia. On the basis of the principles of activity-based costing, detailed hospital costs were estimated for each procedure and compared with the relevant diagnosis-related group (DRG) reimbursement. In 2004, the Reggio Emilia hospital performed 806 angioplasty procedures for a total expenditure of euro 5,176,268. These were 93 plain old balloon angioplasty procedures (euro 487,329), 401 procedures with bare-metal stents (euro 2,380,071), 249 procedures with DESs (euro 1,827,386) and 63 mixed procedures (euro 481,480). Reimbursements amounted to euro 5,816,748 (11% from plain old balloon angioplasty, 50% from bare-metal stent, 31% from DES and 8% from mixed procedures) with a positive margin of about euro 680,480 between costs incurred and reimbursements obtained, even if the reimbursement for DES and mixed procedures was not covering all the incurred costs. Analysis of the case-mix of procedures revealed that an overall positive margin between costs and DRG reimbursements was achieved. It therefore emerges that adherence to the indications of the Healthcare Agency of the Emilia Romagna Region for the appropriate clinical use of DESs is economically sustainable from the hospital enterprise point of view, although the DRG reimbursements are not able to differentiate among resource consumptions owing to the adoption of innovative technologies.

    We aimed to evaluate the impact of thrombus aspiration (TA) during primary percutaneous coronary intervention (P-PCI) in 'real-world' settings. We performed a retrospective study, using data from the National Registry of Interventional Cardiology (RNCI 2006-2012, Portugal) with ST-elevation myocardial infarction (STEMI) patients treated with P-PCI. The primary outcome, in-hospital mortality, was analysed through adjusted odds ratio (aOR) and 95% confidence intervals (95%CI). We assessed data for 9458 STEMI patients that undergone P-PCI (35% treated with TA). The risk of in-hospital mortality with TA (aOR 0.93, 95%CI:0.54-1.60) was not significantly decreased. After matching patients through the propensity score, TA reduced significantly the risk of in-hospital mortality (OR 0.58, 95%CI:0.35-0.98; 3500 patients). The whole cohort data does not support the routine use of TA in P-PCI, but the results of the propensity-score matched cohort suggests that the use of selective TA may improve the short-term risks of STEMI.

    The current importance of the interventional therapy of coronary artery disease may be deduced from the exponential increase in procedures performed in Germany in the last decade - at least 125,840 in 1996. Today, by improved catheter and balloon materials as well as by growing experience of the cardiologists, even complex lesions may be treated. Limitations of balloon angioplasty include acute vessel closure and restenosis - newer angioplasty devices like directional or rotational atherectomy or excimer-laser angioplasty did not overcome these limitations; only by coronary stenting, acute vessel closure could be managed and the likelihood of restenosis - at least in particular groups of patients - could be reduced. For a few years, intracoronary brachytherapy of the segments dilated with beta- or gamma-emitters has been seeking to reduce restenosis rate; the department of cardiology of the Dresden Cardiovascular Institute is participating in such a multicentre study using the beta-emitter {sup 188}renium. Further main topics of our department represent primary angioplasty in patients with acute myocardial infarction and invasive diagnostic or interventional procedures by the transradial approach.

    Very few women become interventional cardiologists, although a substantial proportion of cardiologists and the majority of medical students are women. In accordance with the EAPCI Women Committee mission of attaining gender equality at the professional level, a worldwide survey was recently conducted aiming to understand better the motivations and the barriers for women in selecting interventional cardiology (IC) as a career path. A total of 1,787 individuals (60.7% women) responded to the survey. Women compared to men were less frequently married (women vs. men, 57.0% vs. 79.8%, pmen replying to why, in their opinion, women do not choose IC, on-calls and long working hours were the most frequent reasons (35.3%). Several barriers preclude women from choosing IC, including lack of opportunity, concerns regarding radiation exposure and the prejudices of their male colleagues. This highlights the need to develop new strategies for future training, education, and support of women in order to choose IC.

  8. Maximum skin dose assessment in interventional cardiology: large area detectors and calculation methods

    Advances in imaging technology have facilitated the development of increasingly complex radiological procedures for interventional radiology. Such interventional procedures can involve significant patient exposure, although often represent alternatives to more hazardous surgery or are the sole method for treatment. Interventional radiology is already an established part of mainstream medicine and is likely to expand further with the continuing development and adoption of new procedures. Between all medical exposures, interventional radiology is first of the list of the more expansive radiological practice in terms of effective dose per examination with a mean value of 20 mSv. Currently interventional radiology contribute 4% to the annual collective dose, in spite of contributing to total annual frequency only 0.3% but considering the perspectives of this method can be expected a large expansion of this value. In IR procedures the potential for deterministic effects on the skin is a risk to be taken into account together with stochastic long term risk. Indeed, the International Commission on Radiological Protection (ICRP) in its publication No 85, affirms that the patient dose of priority concern is the absorbed dose in the area of skin that receives the maximum dose during an interventional procedure. For the mentioned reasons, in IR it is important to give to practitioners information on the dose received by the skin of the patient during the procedure. In this paper maximum local skin dose (MSD) is called the absorbed dose in the area of skin receiving the maximum dose during an interventional procedure

    Interventional C-arm systems allow the efficient acquisition of 3D cone beam CT images. They can be used for intervention planning, navigation, and outcome assessment. We present a fast and completely automated volume of interest (VOI) delineation for cardiac interventions, covering the whole visceral cavity including mediastinum and lungs but leaving out rib-cage and spine. The problem is addressed in a model based approach. The procedure has been evaluated on 22 patient cases and achieves an average surface error below 2mm. The method is able to cope with varying image intensities, varying truncations due to the limited reconstruction volume, and partially with heavy metal and motion artifacts.

    In an attempt to deal with the pressures on the health-care system and to guarantee sustainability, changes are needed. This study focuses on a cardiology primary care plus intervention. Primary care plus (PC+) is a new health-care delivery model focused on substitution of specialist care in the hospital setting with specialist care in the primary care setting. The intervention consists of a cardiology PC+ centre in which cardiologists, supported by other health-care professionals, provide consultations in a primary care setting. The PC+ centre aims to improve the health of the population and quality of care as experienced by patients, and reduce the number of referrals to hospital-based outpatient specialist care in order to reduce health-care costs. These aims reflect the Triple Aim principle. Hence, the objectives of the study are to evaluate the cardiology PC+ centre in terms of the Triple Aim outcomes and to evaluate the process of the introduction of PC+. The study is a practice-based, quantitative study with a longitudinal observational design, and an additional qualitative study to supplement, interpret and improve the quantitative study. The study population of the quantitative part will consist of adult patients (≥18 years) with non-acute and low-complexity cardiology-related health complaints, who will be referred to the cardiology PC+ centre (intervention group) or hospital-based outpatient cardiology care (control group). All eligible patients will be asked to complete questionnaires at three different time points consisting of questions about their demographics, health status and experience of care. Additionally, quantitative data will be collected about health-care utilization and related health-care costs at the PC+ centre and the hospital. The qualitative part, consisting of semi-structured interviews, focus groups, and observations, is designed to evaluate the process as well as to amplify, clarify and explain quantitative results.

    Full Text Available Abstract Background A major change has occurred in the last few years in the therapeutic approach to patients presenting with all forms of acute coronary syndromes. Whether or not these patients present initially to tertiary cardiac care centers, they are now routinely referred for early coronary angiography and increasingly undergo percutaneous revascularization. This practice is driven primarily by the angiographic image and technical feasibility. Concomitantly, there has been a decline in expectant or ischemia-guided medical management based on specific clinical presentation, response to initial treatment, and results of noninvasive stratification. This 'tertiarization' of acute coronary care has been fuelled by the increasing sophistication of the cardiac armamentarium, the peer-reviewed publication of clinical studies purporting to show the superiority of invasive cardiac interventions, and predominantly supporting (non-peer-reviewed editorials, newsletters, and opinion pieces. Discussion This review presents another perspective, based on a critical reexamination of the evidence. The topics addressed are: reperfusion treatment of ST-elevation myocardial infarction; the indications for invasive intervention following thrombolysis; the role of invasive management in non-ST-elevation myocardial infarction and unstable angina; and cost-effectiveness and real world considerations. A few cases encountered in recent practice in community and tertiary hospitals are presented for illustrative purposes The numerous and far-reaching scientific, economic, and philosophical implications that are a consequence of this marked change in clinical practice as well as healthcare, decisional and conflict of interest issues are explored. Summary The weight of evidence does not support the contemporary unfocused broad use of invasive interventional procedures across the spectrum of acute coronary clinical presentations. Excessive and unselective recourse to

    The radiation doses from interventional procedures is relevant when treating children because of their greater radiosensitivity compared with adults. The purposes of this paper were to estimate the dose received by 18 pediatric patients who underwent cardiac interventional procedures and to correlate the maximum entrance surface air kerma (Ke,max), estimated with radiochromic films, with the cumulative air kerma values displayed at the end of procedures. This study was performed in children up to 6 years. The study was performed in two hospitals, one located in Recife and the other one in São Paulo. The x-ray imaging systems used were Phillips Allura 12 model with image intensifier system and a Phillips Allura FD10 flat panel system. To estimate the Ke,max on the patient’s skin radiochromic films(Gafchromic XR-RV2) were used. These values were estimated from the maximum optical density measured on film using a calibration curve. The results showed cumulative air kerma values ranging from 78.3- 500.0mGy, with a mean value of 242,3 mGy. The resulting Ke,max values ranged from 20.0-461.8 mGy, with a mean value of 208,8 mGy. The Ke,max values were correlated with the displayed cumulative air kerma values. The correlation factor R² was 0.78, meaning that the value displayed in the equipment’s console can be useful for monitoring the skin absorbed dose throughout the procedure. The routine fluoroscopy time records is not able by itself alert the physician about the risk of dose exceeding the threshold of adverse reactions, which can vary from an early erythema to serious harmful skin damage.

    This article provides a brief summary of the relevant recommendations and references related to percutaneous mechanical circulatory support. The goal was to provide the clinician with concise, evidence-based contemporary recommendations, and the supporting documentation to encourage their application. The full text includes disclosure of all relevant relationships with industry for each writing committee member. A fundamental aspect of all expert consensus statements is that these carefully developed, evidence-based documents can neither encompass all clinical circumstances, nor replace the judgment of individual physicians in management of each patient. The science of medicine is rooted in evidence, and the art of medicine is based on the application of this evidence to the individual patient. This expert consensus statement has adhered to these principles for optimal management of patients requiring percutaneous mechanical circulatory support. © 2015 by The Society for Cardiovascular Angiography and Interventions, The American College of Cardiology Foundation, the Heart Failure Society of America, and The Society for Thoracic Surgery.

    The indications for catheter-based structural and electrophysiological procedures have recently expanded to more complex scenarios, in which an accurate definition of the variable individual cardiac anatomy is key to obtain optimal results. Intracardiac echocardiography (ICE) is a unique imaging modality able to provide high-resolution real-time visualization of cardiac structures, continuous monitoring of catheter location within the heart, and early recognition of procedural complications, such as pericardial effusion or thrombus formation. Additional benefits are excellent patient tolerance, reduction of fluoroscopy time, and lack of need for general anesthesia or a second operator. For these reasons, ICE has largely replaced transesophageal echocardiography as ideal imaging modality for guiding certain procedures, such as atrial septal defect closure and catheter ablation of cardiac arrhythmias, and has an emerging role in others, including mitral valvuloplasty, transcatheter aortic valve replacement, and left atrial appendage closure. In electrophysiology procedures, ICE allows integration of real-time images with electroanatomic maps; it has a role in assessment of arrhythmogenic substrate, and it is particularly useful for mapping structures that are not visualized by fluoroscopy, such as the interatrial or interventricular septum, papillary muscles, and intracavitary muscular ridges. Most recently, a three-dimensional (3D) volumetric ICE system has also been developed, with potential for greater anatomic information and a promising role in structural interventions. In this state-of-the-art review, we provide guidance on how to conduct a comprehensive ICE survey and summarize the main applications of ICE in a variety of structural and electrophysiology procedures. © 2018 American Heart Association, Inc.

    Purpose: The aim of this study was to present the results of a pilot program on patient dosimetry carried out in Chile during the last 5 yr, using a biplane x-ray angiography system settled for pediatrics. This research was conducted in Latin America under the auspices of the International Atomic Energy Agency (IAEA) supporting programs on radiological protection (RP) of patients. Methods: Patient age, gender, weight, height, number of cine series, total number of cine frames, fluoroscopy time, and two dosimetric quantities [air kerma-area product (P ka ) and cumulative dose (CD) at the patient entrance reference point] were recorded for each procedure. Results: The study includes 544 patients grouped into four age groups. The distributions by age group were 150 for ka and CD for the four age groups were 0.94, 1.46, 2.13, and 5.03 Gy cm 2 and 23.9, 26.8, 33.5, and 51.6 mGy, respectively. No significant statistical differences were found between diagnostic and therapeutic procedures. A moderate correlation (r = 0.64) was seen between P ka and patient weight. Conclusions: The dose values reported in this paper were lower than those published in the previous work for the same age groups as a result of the optimization actions carried out by cardiologists and medical physicists with the support of the IAEA. Methodology and results will be used as a starting point for a wider survey in Chile and Latin America with the goal to obtain regional diagnostic reference levels as recently recommended by the International Commission on Radiological Protection for interventional procedures.

    The birth of nuclear cardiology has generally been attributed to a 1927 experiment during which a radium salt was injected in one arm vein and the circulation time calculated by recording the arrival of the radioactivity in the opposite arm. This simple experiment lead to the radiocardiogram in the late 1940s that was used to measure left ventricular function and, later, cardiac output. This chapter provides a brief overview of nuclear cardiology. Methodology is presented when it is important for the understanding of test results. The use of these studies in the diagnosis and evaluation of patients with suspected cardiovascular disease is emphasized

    Full text of publication follows: Protection of medical personnel in interventional cardiology is now days one of the most important issues of radiological protection. Due to the rapid increase of coronary heart disease in developed and developing countries, application of interventional techniques such as coronary angiography and angioplasty have also increased sharply over past two decades. While these procedures are carried out cardiologists and their assistants are remained close to the patient and within the hot area of the radiation field. Therefore they are subject to receive significant doses of radiation. In this study doses received by critical and more vulnerable organs of cardiologists and their assistants were measured by thermoluminescent dosimeters (T.L.D.). T.L.D. measurements were carried for 115 coronary angiography (C.A.) and 30 pre-cutaneous transluminal coronary angioplasty (P.T.C.A.) procedures at teaching general hospitals in Mashhad-Iran. Doses received by thyroid, gonad, right and left hands of the study groups were measured. For this purpose T.L.D. were placed on and underneath of the lead apron adjacent to gonads and on the wrist of both hands. The results of this study imply that: a) For both groups left hands are subject to receiving the highest mean dose (0.18 mGy/P.T.C.A.) b) Thyroid mean dose per P.T.C.A. received by the T.L.D. chips on the shield is 0.72 mGy and is much higher than corresponding value for the T.L.D. placed underneath the shield. c) Gonads would receive the highest mean dose per P.T.C.A. (0.16 mGy), second to left hand, if lead apron is not worn, but lead apron reduces the dose by a factor of nearly six. d) General speaking assistants, mostly stood on the right side of cardiologists, receive smaller dose. e) P.T.C.A. induces a higher dose to all organs of both cardiologists and their assistants when compared with the corresponding doses arising from C.A. procedure.

    Education of medical students in cardiology requires access to patients having a variety of different forms of heart disease. But bringing together student, instructor and patient is a difficult and expensive process that does not benefit the patient. An alternate approach is substitution of a lifelike mannequin capable of simulating many conditions of heart disease. The mannequin pictured below, together with a related information display, is an advanced medical training system whose development benefited from NASA visual display technology and consultative input from NASA's Kennedy Space Center. The mannequin system represents more than 10 years of development effort by Dr. Michael S. Gordon, professor of cardiology at the University of Miami (Florida) School of Medicine.

    In recent years, the number of interventional cardiology procedures is increasing. However, due to the long time of fluoroscopy in these procedures, care teams can receive high doses of radiation. The radiation scattered by the patient is not uniform, and their assessment is of utmost importance. This study aimed to estimate and map the kerma rate in the air at the time of the gonads, in an interventional cardiology room, seeking to optimize the dose absorbed by individuals occupationally exposed to ionizing radiation. For data collection, the room was divided into quadrants of 1m{sup 2}, totaling 40 collection points. The simulator was positioned so that its entry surface was located in the interventional reference point. Were chosen the conditions that simulate angiography and angioplasty procedures performed in the service. The data were obtained for height of 1 meter, gonad region. The results obtained for kerma rates in air, in quadrants, show that higher measured values was in the vicinity of the X-ray tube. Has been found that the medical staff are more exposed, because of its location during the procedure, around the table. The law of the inverse square distance of the farthest points of the X-ray tube were verified.

    Invasive cardiology laboratory workers are occupationally exposed to chronic ionizing radiation. It is known that ionizing radiation has a damaging effect on chromosomes. In present study, we investigated the frequency of sister chromatid exchange (SCE) and chromosomal aberrations in 11 invasive cardiology laboratory workers and 11 healthy controls. After a vacation period, we took blood samples for chromosome analysis in months 0, 4, 8 and 12 (last two month period was the nonradiation time). The SCE frequencies did not change significantly after exposure to ionizing radiation in any worker. Our study has revealed that non-specific structural chromosome aberrations such as gaps, isogaps, acentric chromosomes, chromatids and chromosome breakage could be in the 4th and 8th months after ionizing radiation exposure in the metaphase plaques. All abnormal chromosomal effects had disappeared by the end of the two month non-exposure period in each worker. In conclusion, the results suggest that SCE frequencies are not significantly affected in invasive cardiology laboratory workers who are exposed occupationally to ionizing radiation, although some degree of reversible chromosomal aberrations did appear.

    A wide variation in patient exposure has been observed in interventional radiology and cardiology. The purpose of this study was to investigate the patient dose from fluoroscopy-guided procedures performed in non-academic centres when compared with academic centres. Four procedures (coronary angiography, percutaneous coronary intervention, angiography of the lower limbs and percutaneous transluminal angioplasty of the lower limbs) were evaluated. Data on the dose-area product, fluoroscopy time and number of images for 1000 procedures were obtained from 23 non-academic centres and compared with data from 5 academic centres. No differences were found for cardiology procedures performed in non-academic centres versus academic ones. However, significantly lower doses were delivered to patients for procedures of the lower limbs when they were performed in non-academic centres. This may be due to more complex procedures performed in the academic centres. Comparison between the centres showed a great variation in the patient dose for these lower limb procedures. (authors)

    The present review provides a selected choice of clinical trials and therapeutic advances in the field of cardiology in 2015. A new treatment option in heart failure will become available this year in Switzerland. In interventional cardiology, new trials have been published on the duration of dual antiplatelet therapy, the new stents with bioresorbable scaffold and the long-term results of TAVR in patients who are not surgical candidates or at high surgical risk. RegardingAF the BRIDGE trial provides new evidences to guide the management of patients during warfarin interruption for surgery. Recent publications are changing the paradigm of AF treatment by showing a major impact of the management of cardiometabolic risk factors. Finally, refined criteria for ECG interpretation in athletes have been recently proposed to reduce the burden of false-positive screening.

    The purpose of this work is to investigate removal of the anti-scatter grid and alteration of the frame rate in paediatric interventional cardiology (IC) and assess the impact on radiation dose and image quality. Phantom based experimental studies were performed in a dedicated cardiac catheterisation suite to investigate variations in radiation dose and image quality, with various changes in imaging parameters. Phantom based experimental studies employing these variations in technique identified that radiation dose reductions of 28%–49% can be made to the patient with minimal loss of image quality in smaller sized patients. At present, there is no standard technique for carrying out paediatric IC in the UK or Ireland, resulting in the potential for a wide variation in radiation dose. Dose reductions to patients can be achieved with slight alterations to the imaging equipment with minimal compromise to the image quality. These simple modifications can be easily implemented in clinical practice in IC centres. (paper)

    The paper is aimed at making a proposal for the type test and calibration of eye lens passive dosemeters especially used in the interventional cardiology/radiology (IC/IR). Starting from the only existing standard dealing with eye lens dosimetry using TLDs (), parameters such as, detection threshold, energy and angle dependence of response criteria have been reviewed and it has been tried to harmonise them as much as possible with the IEC 62387 requirements, taking into account the particular use at IC/IR workplaces. Conversion coefficients from air kerma to dose equivalent at 3 mm depth for RQR and ISO radiation qualities, employed for type test and calibration purposes, have been calculated in a new phantom introduced within the ORAMED (Optimization of RAdiation protection for MEDical staff) project. This phantom is more representative of the head so that the estimation of H lens by H p (3) is more accurate.

    Cardiologist and other staff members receive high doses of scattered radiation. Cases of radiation-induced cataract among cardiology professionals have been reported in studies, estimates for the dose to eye lens ranged from 450 to 900 mSv per year (without ceiling suspended screen), over several years. Recent surveys regarding high prevalence of lens changes likely induced by radiation exposure suggest an urgent need for improved radiation safety and training, use of eye protection during catheterization procedures, and improved occupational dosimetry. In view of the evidence of radiation injuries, the ICRP recommends limiting the radiation dose to the lens to 20 mSv per year for occupational exposure. A system for optimizing the radiation exposure is the measurement of entrance surface air kerma (K{sub a,e}) and kerma-area product (P{sub KA}) for patient and scattered dose or dose rate at the position for the staff, under clinical working conditions using phantoms and defined technical factors. Correlating K{sub a,e} and P{sub KA} with the scatter dose, applying the attenuation factors protective devices can enable estimation of the lens doses for operators. The purpose of this work is: to study the possibility of establishing a procedure which is useful for scientific societies and the regulatory authority in the prevention and control of IOE dose and to control and improve the quality of procedures in interventional cardiology as an initiative to raise awareness and optimization of radiological protection. Measurements were taken in different cardiac laboratories. Clinical working conditions were reproduced during the experiments for the different hemodynamic angiographic projections and operating modes used in fluoroscopy and cine. A first K{sub a,e} rate reference proposal for the characterization of angiography for the different acquisition modes were 16; 35; 40 and 220 (mGy/min), respectively.

    This thesis deals with two topics in nuclear cardiology. In the first, left ventricular wall motion assessment using Fourier transform of local left ventricular time-activity curves in gated blood pool studies is evaluated. In the second, the interpretation of myocardial perfusion scintigrams is assessed which are obtained with thallium-201 or with another radiopharmaceutical with different physical, but identical biological properties. In all these investigations data acquisition and analysis by computer played an essential role. In chapter 1 the desirable properties of a nuclear medicine computer system are given and the computer system used for this work is described. Wall motion analysis of the left ventricle using Fourier transform of local time-activity curves in the left ventricular region in gated blood pool studies is described in chapter 2. In chapter 3 detection of non-perfused lesions in myocardial perfusion scintigraphy with thallium-201 is described. Detection of partly perfused lesions and the influence of scatter and photon energy on myocardial perfusion scintigraphy is described in chapter 4. (Auth.)

    Full Text Available In the year 2014, there were certain remarkable trials that have changed the practice of cardiology and beyond that these tried to explained some long awaited unanswered questions. Like SIMPLICITY HTN-3 trial clearly explained the uselessness of renal denervation therapy in systemic hypertension. PARADIGM-HF trial provided positive data that may be useful to enrich the basket of medical treatment with a new drug LCZ 696 after a long time. Another important meta-analysis in heart failure questioned the status of beta blockers as standard therapy to improve prognosis in patients with concomitant heart failure and atrial fibrillation . In myocardial infraction , CvLPRIT trial supported the concept of complete revascularization at the time of primary PCI and TASTE trials failed to show expected benefit of thrombus aspiration in acute MI. FFR got more strength from FAME 2 trial. Another important question that was addressed in SECURITY trial was optimal duration of DAPT after second generation DES implantation. One year follow-up results of ABSORB II suggested that bioresorbable scaffolds are currently facing problem of stent thrombosis that might be taken care in near future with improvement in strut technology. Successful use of "Heart in a box" machine provided a major thrust for cardiac transplantation. SEARCH-AF evaluated the efficacy of a novel mobile health technology in the real world to screen for atrial fibrillation (now called as life style disease. A Meta-analysis provided a more comprehensive picture of the new oral anticoagulants as a therapeutic option in atrial fibrillation. Positive results for trans catheter pm-VSD closure in paediatric population were also demonstrated by a randomized controlled trial. Role of corticosteroids in tubercular pericarditis also got the answer in a trial published in 2014.

    Unlike other techniques, nuclear cardiologic imaging enables evaluation of cardiac function employing radioactive tracers. This procedure can be used to assess myocardial blood flow, metabolism, viability, cardiac innervation and receptor status. Therefore, this noninvasive imaging modality can be regarded as supplementary to the screening methods in cardiology and also to angiography. General clinical use was not possible until the rapid development of nuclear medicine in the fifties began. With increasing wide-spread of positron emission tomography more detailed information on metabolic tissue characterization can be expected and will be of enormous relevance in clinical decision making and in selecting patients for interventions.

    Although historically the intra-aortic balloon pump has been the only mechanical circulatory support device available to clinicians, a number of new devices have become commercially available and have entered clinical practice. These include axial flow pumps, such as Impella(®); left atrial to femoral artery bypass pumps, specifically the TandemHeart; and new devices for institution of extracorporeal membrane oxygenation. These devices differ significantly in their hemodynamic effects, insertion, monitoring, and clinical applicability. This document reviews the physiologic impact on the circulation of these devices and their use in specific clinical situations. These situations include patients undergoing high-risk percutaneous coronary intervention, those presenting with cardiogenic shock, and acute decompensated heart failure. Specialized uses for right-sided support and in pediatric populations are discussed and the clinical utility of mechanical circulatory support devices is reviewed, as are the American College of Cardiology/American Heart Association clinical practice guidelines.

    Purpose To determine the prevalence of and risk factors for needlesticks in interventional radiology physicians, as well as the attitudes, behaviors, and conditions that promote or interfere with reporting of these injuries. Materials and Methods A total of 3889 interventional radiologists from academic and private practice in the United States were surveyed by emailing all interventional radiologist members of the Society of Interventional Radiology, including attending-level physicians and trainees (April-August 2016). The institutional review board waived the need for consent. Questions inquired about the nature, frequency, and type of needlestick and sharps injuries and whether and to whom these incidents were reported. Stepwise regression was used to determine variables predicting whether injuries were reported. Results In total, 908 (23%) interventional radiologists completed at least a portion of the survey. Eight hundred fourteen (91%) of 895 respondents reported a prior needlestick injury, 583 (35%) of 895 reported at least one injury while treating an HIV-positive patient, and 626 (71%) of 884 reported prior training regarding needlestick injury. There was, on average, one needlestick for every 5 years of practice. Most needlestick or sharps injuries were self inflicted (711 [87%] of 817) and involved a hollow-bore device (464 [56%] of 824). Only 566 (66%) of 850 injuries were reported. The most common reasons for not reporting included perceived lack of utility of reporting (79 [28%] of 282), perceived low risk for injury (56 [20%] of 282), noncontaminated needle (53 [19%] of 282), too-lengthy reporting process (37 [13%] of 282), and associated stigma (23 [8%] of 282). Only 156 (25%) of 624 respondents informed their significant other. Stepwise regression assessing variables affecting the likelihood of reporting showed that male sex (P = .009), low-risk patient (P < .0001), self injury (P = .010), trainee status (P < .0001), and the total number of prior

    Background: Transradial approach (TRA) for percutaneous coronary procedures is associated with improved patient outcome and is being increasingly adopted worldwide. We surveyed Italian interventional cardiologists in order to take a snapshot of the current practice of TRA. Methods: A web-based questionnaire was emailed to all members of the Italian Society of Interventional Cardiology. Results: The survey was taken by 508 respondents. Cardiogenic shock and chronic total occlusions represented the principal limitations to TRA. Right TRA was the default approach for 81% of respondents. Both diagnostic and interventional procedures were routinely performed through 6 Fr sheaths (83% and 93%, respectively); dedicated TRA curves were used in 11% of diagnostic and in about 3% of interventional procedures. Almost 70% of the operators did not assess dual hand circulation. In case of crossover, the contralateral radial artery was the preferred site (57%). Radial artery hemostasis was mostly achieved by pneumatic bracelet (64%) and patency of the radial artery during hemostasis was ensured in 60% of cases. Pre-discharge patency of the radial artery was routinely assessed by almost 60% of respondents. For diagnostic procedures, adequate heparin anticoagulation (5000 IU) was only given by 45% of operators. Most respondents believed that TRA is associated with greater radiation exposure for both the patient (82%) and the operator (98%) as compared to transfemoral approach. Conclusions: This survey provides contemporary data about the adoption of TRA in Italy and gives interesting insights about several technical and clinical issues related to the practice of this vascular approach for coronary procedures. - Highlights: • Transradial approach for coronary procedures is becoming increasingly popular. • We conducted a survey on the contemporary practice of transradial approach in Italy. • We appraised several clinical and technical issues related to transradial approach.

    This study evaluated the feasibility, safety, and effectiveness of endovascular interventions for common femoral artery (CFA) occlusive disease. Using a prospectively maintained multicenter database, we analyzed outcomes in 167 consecutive patients who underwent percutaneous CFA interventions for Rutherford class 3 to class 6 (R3-R6) disease. The standardized treatment approach included primary percutaneous transluminal angioplasty (PTA) only, atherectomy + PTA, and provisional stenting. Outcomes included technical failure rate, recurrence, complications, and major or minor amputation rate. Data were analyzed using multivariate regression analysis. During a 7-year period, 167 patients with R3 (n = 91 [54.5%]) and R4 to R6 (n = 76 [45.5%]) disease underwent CFA interventions that included PTA only (n = 114 [68.2%]), atherectomy ± PTA (n = 38 [22.8%]), and provisional stenting (n = 15 [9.0%]) for failed atherectomy ± PTA. Procedure-related complications included pseudoaneurysm (n = 1 [0.6%]), thrombosis (n = 1 [0.6%]), distal embolization (n = 1 [0.6%]), and death (R6, n = 1 [0.06%]). CFA restenosis was observed in 34 (20.4%) patents; these underwent further percutaneous (n = 18 [10.8%]) or surgical (n = 17 [10.2%]) revascularization that included CFA endarterectomy ± femoral distal bypass. Major or minor amputations were observed in none of the R3 patients and in only three (3.9%) and five (6.5%) of the R4 to R6 patients, respectively. Compared with the atherectomy + PTA group, patients in the PTA-only group had a significantly lower patency. Furthermore, during long-term mean follow-up of 42.5 months, the CFA provisional stent group had a 100% primary patency, which was significantly better than the primary patency in the CFA nonstent groups combined (77.0%; P = .0424). Data from this study to date would suggest that percutaneous CFA interventions in select patients are relatively safe and effective. In the long term, CFA stenting has

    Innovations in interventional cardiology historically predate those in neuro-intervention. As such, studying trends in interventional cardiology can be useful in exploring avenues to optimise neuro-interventional techniques. One such cardiology innovation has been the steady conversion of arterial puncture sites from transfemoral access (TFA) to transradial access (TRA), a paradigm shift supported by safety benefits for patients. While neuro-intervention has unique anatomical challenges, the access itself is identical. As such, examining the extensive cardiology literature on the radial approach has the potential to offer valuable lessons for the neuro-interventionalist audience who may be unfamiliar with this body of work. Therefore, we present here a report, particularly for neuro-interventionalists, regarding the best practices for TRA by reviewing the relevant cardiology literature. We focused our review on the data most relevant to our audience, namely that surrounding the access itself. By reviewing the cardiology literature on metrics such as safety profiles, cost and patient satisfaction differences between TFA and TRA, as well as examining the technical nuances of the procedure and post-procedural care, we hope to give physicians treating complex cerebrovascular disease a broader data-driven understanding of TRA. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    This study evaluates per-procedure, collective and per capita effective dose to the population by interventional cardiology (IC) procedures performed during 2002–11 at the main hospital of Aosta Valley Region that can be considered as representative of the health-care level I countries, as defined by the UNSCEAR, based on its socio-demographic characteristics. IC procedures investigated were often multiple procedures in patients older than 60 y. The median extreme dose-area product values of 300 and 22 908 cGycm2 were found for standard pacemaker implantation and coronary angioplasty, respectively, while the relative mean per-procedure effective dose ranged from 0.7 to 47 mSv. A 3-fold increase in frequency has been observed together with a correlated increase in the delivered per capita dose (0.05–0.27 mSv y−1) and the collective dose (5.8–35 man Sv y−1). Doses increased particularly from 2008 onwards mainly because of the introduction of coronary angioplasty procedures in the authors’ institution. IC practice contributed remarkably in terms of effective dose to the population, delivering ∼10 % of the total dose by medical ionising radiation examination categories. PMID:26012484

    The authors review percutaneous coronary intervention (PCI) evolution and its growing application in myocardial revascularization for patients with coronary heart disease in Brazil and worldwide. PCI was introduced in 1977 using only the catheter balloon. Limitations of this method (acute occlusion and coronary restenosis) led to the adoption of coronary stents and more recently the advent of drug-eluting stents2, which were developed to drastically reduce restenosis rates. These developments allowed the exponential growth of percutaneous coronary intervention (PCI) procedures in Brazil which have replaced many bypass surgery procedures and have become the gold standard for the majority of symptomatic patients suffering from coronary artery disease. The preference for this procedure gained new dimensions in 2000 when the Brazilian Public Healthcare System (SUS) began reimbursing for stent procedures. This measure exemplified the importance of the Public Healthcare System's participation in incorporating medical advances and offering a high standard of cardiovascular treatment to a large portion of the Brazilian population. It is emphasized that prevention of in-stent restenosis is complex due to its unpredictable and ubiquitous occurrence. Control of this condition improves quality of life and reduces the recurrence of angina pectoris, the need to perform new revascularization procedures and hospital readmissions. The overall success of the drug-eluting stents has proven to be reliable and consistent in overcoming restenosis and has some beneficial impact for all clinical and angiographic conditions. This paper discusses the adoption and criteria for the use of drug-eluting stents in other countries as well as the recommendations established by the Brazilian Society of Interventional Cardiology for their reimbursement by SUS. The incorporation of new healthcare technology involves two distinct stages. During the first stage, the product is registered with the

    Antiplatelet therapy (APT) has become an important tool in the treatment and prevention of atherosclerotic events, particularly those associated with coronary artery disease. A large evidence base has evolved regarding the relationship between APT prescription in various clinical contexts and risk/benefit relationships. The Guidelines Committee of the Canadian Cardiovascular Society and Canadian Association of Interventional Cardiology publishes regular updates of its recommendations, taking into consideration the most recent clinical evidence. The present update to the 2011 and 2013 Canadian Cardiovascular Society APT guidelines incorporates new evidence on how to optimize APT use, particularly in situations in which few to no data were previously available. The recommendations update focuses on the following primary topics: (1) the duration of dual APT (DAPT) in patients who undergo percutaneous coronary intervention (PCI) for acute coronary syndrome and non-acute coronary syndrome indications; (2) management of DAPT in patients who undergo noncardiac surgery; (3) management of DAPT in patients who undergo elective and semiurgent coronary artery bypass graft surgery; (4) when and how to switch between different oral antiplatelet therapies; and (5) management of antiplatelet and anticoagulant therapy in patients who undergo PCI. For PCI patients, we specifically analyze the particular considerations in patients with atrial fibrillation, mechanical or bioprosthetic valves (including transcatheter aortic valve replacement), venous thromboembolic disease, and established left ventricular thrombus or possible left ventricular thrombus with reduced ejection fraction after ST-segment elevation myocardial infarction. In addition to specific recommendations, we provide values and preferences and practical tips to aid the practicing clinician in the day to day use of these important agents. Copyright © 2018.

    Radiographic technology plays an integral role in interventional cardiology. The number of interventions continues to increase, and the associated radiation exposure to patients and personnel is of major concern. This study was undertaken to determine whether a newly developed x-ray tube deploying grid-switched pulsed fluoroscopy and extra beam filtering can achieve a reduction in radiation exposure while maintaining fluoroscopic images of high quality. Three fluoroscopic techniques were compared: continuous fluoroscopy, pulsed fluoroscopy, and a newly developed high-output pulsed fluoroscopy with extra filtering. To ascertain differences in the quality of images and to determine differences in patient entrance and investigator radiation exposure, the radiated volume curve was measured to determine the required high voltage levels (kVpeak) for different object sizes for each fluoroscopic mode. The fluoroscopic data of 124 patient procedures were combined. The data were analyzed for radiographic projections, image intensifier field size, and x-ray tube kilovoltage levels (kVpeak). On the basis of this analysis, a reference procedure was constructed. The reference procedure was tested on a phantom or dummy patient by all three fluoroscopic modes. The phantom was so designed that the kilovoltage requirements for each projection were comparable to those needed for the average patient. Radiation exposure of the operator and patient was measured during each mode. The patient entrance dose was measured in air, and the operator dose was measured by 18 dosimeters on a dummy operator. Pulsed compared with continuous fluoroscopy could be performed with improved image quality at lower kilovoltages. The patient entrance dose was reduced by 21% and the operator dose by 54%. High-output pulsed fluoroscopy with extra beam filtering compared with continuous fluoroscopy improved the image quality, lowered the kilovoltage requirements, and reduced the patient entrance dose by 55% and

    Cardiovascular disease in reptiles generally is considered an uncommon finding in captive animals, but no large-scale, cross-sectional studies have been performed to determine its prevalence. It is possible that cardiovascular disease is more common than is generally accepted and that the current belief results from limited clinical and diagnostic experience. This article offers guidance drawn from the author's clinical experience and the available literature. It is important that veterinarians pursue a thorough history, physical examination, and diagnostic work-up when managing cardiovascular disease in a reptile case. Veterinarians working with these cases should document their findings and share them with their colleagues to build an evidence-based foundation for reptile medicine.

    Auditory verbal hallucinations (AVH: 'hearing voices') are found in both schizophrenia and post-traumatic stress disorder (PTSD). In this paper we first demonstrate that AVH in these two diagnoses share a qualitatively similar phenomenology. We then show that the presence of AVH in schizophrenia is often associated with earlier exposure to traumatic/emotionally overwhelming events, as it is by definition in PTSD. We next argue that the content of AVH relates to earlier traumatic events in a similar way in both PTSD and schizophrenia, most commonly having direct or indirect thematic links to emotionally overwhelming events, rather than being direct re-experiencing. We then propose, following cognitive models of PTSD, that the reconstructive nature of memory may be able to account for the nature of these associations between trauma and AVH content, as may threat-hypervigilance and the individual's personal goals. We conclude that a notable subset of people diagnosed with schizophrenia with AVH are having phenomenologically and aetiologically identical experiences to PTSD patients who hear voices. As such we propose that the iron curtain between AVH in PTSD (often termed 'dissociative AVH') and AVH in schizophrenia (so-called 'psychotic AVH') needs to be torn down, as these are often the same experience. One implication of this is that these trauma-related AVH require a common trans-diagnostic treatment strategy. Whilst antipsychotics are already increasingly being used to treat AVH in PTSD, we argue for the centrality of trauma-based interventions for trauma-based AVH in both PTSD and in people diagnosed with schizophrenia.

    Purpose: In this study the use of flat detector computed tomography (FD-CT) in the catheterization of patients with congenital heart disease was evaluated. Application reports were created for various issues based on the achieved image quality in diverse anatomical regions. Materials and Methods: FD-CT was applied in 176 cases during catheterization between January 2010 and April 2012. A five-point Likert scale ('essential' to 'misleading') was used to evaluate image quality. All cases were analyzed retrospectively and application reports for the visualization of the aorta, pulmonary arteries, pulmonary veins, semilunar valves, cavopulmonary connections and atrial baffles were generated. Contrast dye consumption and radiation dose were evaluated. Results: During the observation period FD-CT was applied in all 176 cases. The mean patient age was 7.0 years (0.01 - 42.53 years). The clinical value of FD-CT was rated superior to conventional angiography in 96.6 % of the cases and was never rated as 'misleading'. FD-CT was rated 'essential' in 3.4 % of all cases, 'very useful' in 77.3 % of all cases, 'useful' in 15.9 % of all cases and 'not useful' in 3.4 % of all cases. The mean dose-area product was 99 {mu}Gym{sup 2} (19.3 - 1276.6 {mu}Gym{sup 2}), and the used contrast dye was 1.76 ml/kg (0.9 - 5 ml/kg). Application reports for the visualization of different anatomical regions are demonstrated. Conclusion: FD-CT is a new and auxiliary procedure in diagnostic and interventional catheterization of patients with congenital heart disease. Particularly extracardiac structures can be displayed in three-dimensional high resolution and be used for diagnosis, surgical planning and 3 D navigation. (orig.)

    To assess the reliability and low cost of a computerized interventional cardiology (IC) registry to prospectively and systematically collect high-quality data for all consecutive coronary patients referred for coronary angiogram or/and coronary angioplasty. Rigorous clinical practice assessment is a key factor to improve prognosis in IC. A prospective and permanent registry could achieve this goal but, presumably, at high cost and low level of data quality. One multicentric IC registry (CRAC registry), fully integrated to usual coronary activity report software, started in the centre Val-de-Loire (CVL) French region in 2014. Quality assessment of CRAC registry was conducted on five IC CathLab of the CVL region, from January 1st to December 31st 2014. Quality of collected data was evaluated by measuring procedure exhaustivity (comparing with data from hospital information system), data completeness (quality controls) and data consistency (by checking complete medical charts as gold standard). Cost per procedure (global registry operating cost/number of collected procedures) was also estimated. CRAC model provided a high-quality level with 98.2% procedure completeness, 99.6% data completeness and 89% data consistency. The operating cost per procedure was €14.70 ($16.51) for data collection and quality control, including ST-segment elevation myocardial infarction (STEMI) preadmission information and one-year follow-up after angioplasty. This integrated computerized IC registry led to the construction of an exhaustive, reliable and costless database, including all coronary patients entering in participating IC centers in the CVL region. This solution will be developed in other French regions, setting up a national IC database for coronary patients in 2020: France PCI. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

    The best revascularisation method of the unprotected left main artery is a current and evolving topic. A total of 2439 percutaneous coronary interventions (PCI) were registered during a 3-year period. The study included all the patients with PCI of the unprotected left main coronary (n=48) and matched with patients who underwent coronary artery bypass graft (CABG) (n=50). Major adverse cerebral and cardiac events (MACCE) were assessed within the hospital and in outpatients during a 16 month follow up. The cardiovascular risk was greater in the PCI group; logEuroSCORE 16±21 vs. 5±6, P=.001; clinical Syntax 77±74 vs 53±39, P=.04. On admission, the PCI group of patients had a higher frequency of ST segment elevation myocardial infarction (STEMI) and cardiogenic shock. The MACCE were similar in both groups (14% vs. 18%, P=.64). STEMI was less frequent in the PCI group (0% vs. 10%, P=.03). Cardiovascular events were lower in the PCI group (2.3% vs. 18%, P=.01), and there was a decrease in general and cardiac mortality (2.3% vs. 12%, P=.08 y 2.3% vs. 8%, P=.24), on excluding the patients with cardiogenic shock as a presentation. MACCE were similar in both groups in the out-patient phase (15% vs. 12%, P=.46). Survival without MACCE, general and cardiac death were comparable between groups (log rank, P=.38, P=.44 and P=.16, respectively). Even though the clinical and peri-procedural risk profile of the PCI patients were higher, the in-hospital and out-hospital efficacy and safety were comparable with CABG.

    Nuclear cardiology methods have had less impact upon pediatric cardiology than upon adult cardiology. Most pediatric heart disease results from congenital malformations of the heart and great vessels, which is usually discovered in infancy, and is most often treated definitively in infancy or early childhood. Unfortunately, nuclear medicine techniques are limited in their spatial resolution - structures that overlie each other are separated with difficulty. As a result, nuclear cardiology is usually of limited value in the anatomic characterization of the congenital heart abnormalities. Nevertheless, it has been useful in the detection and quantification of the pathophysiologic consequences of many congenital cardiac malformations. The authors review application of nuclear medicine in pediatric cardiology, and attempt to assess each in terms of its clinical utility

    Full text: Carrier-free rhenium-188 (Re-188) is readily available from the alumina-based tungsten-188/rhenium-188 generator system and has many attractive properties for a wide variety of therapeutic applications. The 16.9 h half-life, emission of the 2.2 MeV beta particle and versatile chemistry make Re-188 an important candidate for applications where high radiation penetration is required. In addition, emission of a gamma photon (155 KeV, 15 %) permits evaluation of biodistribution, pharmacokinetics and dosimetry estimates. The long physical half-life of the tungsten-188 (W-188) parent (t 1/2 69 days) and consistent generator performance - with high Re-188 yields and low W-188 parent breakthrough - result in an indefinite shelf-life of several months, dependent on the levels of Re-188 required. Post generator elution in-growth of 62 % of Re-188 after 24 hours in combination with high elution yields (75-85 %) result in 50 % daily yields of the maximal Re-188 available. In addition to research being conducted for the development of a wide variety of new therapeutic radiopharmaceuticals and devices, Re-188 is also being evaluated in physician-sponsored clinical trials in over 15 countries, with applications in nuclear medicine, oncology and interventional cardiology. One major current clinical application involves post-angiographic treatment of arterial segments following PTCA using Re-188 perrhenate or MAG3 liquid-filled balloons as an effective and cost-effective approach for inhibition of the hyperplastic response to vessel damage, which delivers uniform dose to the vessel wall. Re-188-HEDP is being used for palliation of metastatic bone pain palliation. This agent is readily prepared from a simple 'kit' and provides pain palliation as effective as other commercially available agents.

    The dose distributions at the region of eye lens and extremities of staff working in interventional cardiology were analyzed. The doses to physicians and nurses from three hospitals in Poland were measured with TL dosimeters (MCP-N) located on various places near eyebrows, on both fingers, wrists, knees and on the ankle. The procedures under investigation were coronary angiography (CA) and percutaneous coronary intervention (PCI), peacemaker and defibrillator implantations (PM/ICDs), cardiac resynchronization therapy with or without defibrillator implantations (CRT-D or CRT) and radiofrequency ablations (RFA). The study aimed at analyzing the distribution of radiation in selected anatomic regions, determining the typical locations of highest doses and estimating the dose ranges for selected types of procedures. The maximum registered doses per procedure to eye lens and ankle were 1.21 mSv and 1.46 mSv for CA PCI procedures, 0.02 mSv and 0.05 mSv for RFA and 0.13 mSv and 0.51 mSv for PM/ICDs, respectively. The maximum doses to fingers, wrists and knees were, accordingly, 2.11 mSv, 1.07 mSv and 0.77 mSv for CA PCI procedures, 0.38 mSv, 0.20 mSv and 0.04 mSv for RFA ones, 0.50 mSv, 0.25 mSv and 0.01 mSv for PM/ICDs procedures and 2.25 mSv, 1.12 mSv and 0.58 mSv for CRT and CRT-D ones. The factors which might influence the dose like utilized radiation, availability of additional protective equipment and position of the staff with respect to X-ray source were also analyzed. The annual doses for eye lens and extremities were estimated on the basis of individual annual workloads of the physicians participating in the study. The highest annual doses were revealed for physicians performing CA PCI procedures. Annual eye lens doses range up to 247 mSv indicating that the occupational limit for eye lens 150 mSv has been surpassed. In case of extremities the maximal estimated annual doses were 355 mSv, 136 mSv, 55 mSv and 328 mSv, for fingers, wrists, knees and for ankle

    Nuclear cardiology is one of the most active branches of nuclear medicine and plays important role in diagnosis in treatment of CAD patients. Few nuclear cardiology surveys were published in the literature, mostly from developed countries. A nuclear cardiology survey in Iran and analysis of the findings in comparison with other countries may lead to better decision making and improve practice in our country. A questionnaire was sent by mail or e-mail to all nuclear medicine centers in Iran asking for details of nuclear cardiology practice. Also ownership of the centers, number of gamma cameras and number of cardiac studies in each week were recorded. Some centers were studied using telephone interview. From 79 nuclear medicine centers in Iran, 55 centers (69.6%) filled the questionnaire including 28 centers in Tehran and 27 centers in other cities. There was 69 Gamma cameras in these centers, 62.3% with SPECT capability. It is estimated that we may have 100 gamma cameras in Iran. This study showed that about 68287 cardiac studies were done in Iran each year with Myocardial perfusion scan accounting for about 99 2% of the studies. Considering population of the country nuclear cardiology activity will be about 1.05 study/1000/year. Regarding radiotracers used, about 13.5% of studies were done with T I-201, with some centers using only Tc- 99 m-M I B I

    Decision-making is complex in modern medicine and should ideally be based on available data, structured knowledge and proper interpretation in the context of an individual patient. Automated algorithms, also termed artificial intelligence that are able to extract meaningful patterns from data collections and build decisions upon identified patterns may be useful assistants in clinical decision-making processes. In this article, artificial intelligence-based studies in clinical cardiology are reviewed. The text also touches on the ethical issues and speculates on the future roles of automated algorithms versus clinicians in cardiology and medicine in general.

    Although Hippocrates (460-c.375 BC) has been traditionally recognized as the Father of Medicine, the fact that he was seminal in the development of cardiology is much less well known. Evidence is presented to support the notion that Hippocrates could also be considered the Father of Cardiology. Hippocrates also had many of the teachings and practices in common with Confucius (c.551-c.479 BC) and the Yellow Emperor of China (2695-2589 BC). Whereas Confucius was not a physician, the Yellow Emperor was an ancient Chinese physician whose Huang Di Neijing, the Yellow Emperor's Canon of Internal Medicine, is the oldest known treatise of medicine in existence.

    Objective: To detect the radiation field distribution within the room for three commonly-used interventional procedures, in order to provide basic data for the radiation protection and safe operation of staff involved in interventional radiology. Methods: The thermoluminescent dosemeters (TLDs) were placed in different points on the horizontal plane around the interventional table and the vertical plane where the staff often stayed. Based on the selected experimental conditions, the TLDs were grouped to be irradiated. After the experiment, the TLDs were measured in the laboratory to calculate the doses of radiation field. Results: Data obtained at the same position followed basically as cardiovascular intervention > cerebrovascular intervention > liver intervention. Intervention of same type at the same position followed as high-dose group > mid-dose group > low-dose group. These results were consistent with the useful beam doses, and proportional to the fluoroscopy time. A few data with exception were due to measurement error or experimental error. Conclusions: Cerebrovascular and liver interventional procedures resulted in the relatively low radiation doses. The radiation doses at the distance of more than 3 m can be negligible. For cardiovascular interventional procedure, with the decrease of the distance from the X-ray tube, the dose decreased. In the radiation field,the operator, the first assistant and second assistant would exposed to higher dose on the standing points while patients receive lower doses in the head and feet direction.

    Noncommunicable diseases (NCDs) have become the primary health concern for most countries around the world. Currently, more than 36 million people worldwide die from NCDs each year, accounting for 63% of annual global deaths; most are preventable. The global financial burden of NCDs is staggering, with an estimated 2010 global cost of $6.3 trillion (US dollars) that is projected to increase to $13 trillion by 2030. A number of NCDs share one or more common predisposing risk factors, all related to lifestyle to some degree: (1) cigarette smoking, (2) hypertension, (3) hyperglycemia, (4) dyslipidemia, (5) obesity, (6) physical inactivity, and (7) poor nutrition. In large part, prevention, control, or even reversal of the aforementioned modifiable risk factors are realized through leading a healthy lifestyle (HL). The challenge is how to initiate the global change, not toward increasing documentation of the scope of the problem but toward true action-creating, implementing, and sustaining HL initiatives that will result in positive, measurable changes in the previously defined poor health metrics. To achieve this task, a paradigm shift in how we approach NCD prevention and treatment is required. The goal of this American Heart Association/European Society of Cardiology/European Association for Cardiovascular Prevention and Rehabilitation/American College of Preventive Medicine policy statement is to define key stakeholders and highlight their connectivity with respect to HL initiatives. This policy encourages integrated action by all stakeholders to create the needed paradigm shift and achieve broad adoption of HL behaviors on a global scale. © 2015 Mayo Foundation for Medical Education and Research, and the European Society of Cardiology.

    An evaluation is made of the technical and financial feasibility for the change of material of a platinum coil used in guidewires for procedures of cardiological intervention in a company producing medical devices in Costa Rica. The proposed exchange rate on the product has already was marketed. A validation and verification of the design are performed again for the characteristics impacted, in addition to notify the regulatory bodies of the material change and have its prior approval commercialization of the modified product. A radiopacity study of the proposed materials is carried out to evaluate the materials as well as a consultation with suppliers approved by the company to verify the availability of candidate materials. The load of the palladium spring is evaluated with respect to the Platinum spring to three defined extensions and is determined. The project has proposed to save $663 897 for the Palladium coil and $739 175 for the 'A alloy' coil composed mainly of Palladium. The project can be developed according to the financial study, since the savings gains are greater than the investment made by the company for the execution of the product. Deeper radiopacity tests are recommended to perform. Comparison of the current spring with those proposed under fluoroscopy in the field of application. Suppliers' studies have shown that the percentage of visibility of palladium is decreased in the energetic environment in which medical interventions are carried out and the guidewires are used.

    Cardiovascular disease is the most common cause of death in Western countries. Physician adherence to guidelines is often suboptimal, resulting in impaired patient outcome and prognosis. Multiple studies have been conducted to evaluate patterns and the influencing factors of patient adherence, but little is known about factors influencing physician guideline adherence. This review aims to identify factors influencing physician guideline adherence relevant to cardiology and to provide insights and suggestions for future improvement. Physician adherence was measured as adherence to standard local medical practice and applicable guidelines. Female gender and older age had a negative effect on physician guideline adherence. In addition, independent of the type of heart disease, physicians without cardiologic specialization were linked to physician noncompliance. Also, guideline adherence in primary care centers was at a lower level compared to secondary or tertiary care centers. The importance of guideline adherence increases as patients age, and complex diseases and comorbidity arise. Appropriate resources and interventions, taking important factors for nonadherence in account, are necessary to improve guideline adoption and adherence in every level of the chain. This in turn should improve patient outcome.

    Full text: Nuclear Cardiology has maintained a prominent position in the assessment of CAD and has become the end-point in Clinical Trials for the following reasons: Non-invasive assessment of CAD, Assessment of presence, localisation and severity, Widely available, feasible and reproducible, Visualisation of blood flow and pumping. The main areas of cardiology that are amenable to assessment with nuclear cardiology include: Stable and unstable CAD, Acute and post MI, Cardiomyopathy, Valvular disease and shunts, Cardiotoxicity, Aneurysms, Transplants The application of nuclear cardiology in these conditions will help in the management of patients by providing information relating to: Diagnosis and prognosis, Risk stratification, Medical Vs surgical treatment, Haemodynamic significance, Efficiency of management The main application in practical terms is in the assessment of CAD at variable stages: Before, during and after an incident: Before Incident: -Enhancing diagnosis and prognosis in patients with CAD, Providing functional data for changes on angiography. During Incident: -Assessing criteria for admission and further tests. After Incident: -Identifying hibernating myocardium, - Risk stratification. Risk Stratification highlights the outcome following nonfatal MI as the patients may be split into 2 categories: Low-risk group -Comprise 50-66% of patients, -Can be managed with medical treatment High-risk group, -Comprise (34-50%), -Prone to future complications within 3 months (Death, reinfarction, CCF and unstable angina). Viability: Is a spectrum of overlapping clinical states following an incident. Assessment is increasingly requested for evaluation of revascularisation vs cardiac transplant as the outcome will improve regional and global function, CCF symptoms and improve quality of life and survival Why assess viability? Persistent LVD have bad prognosis with EF 50% 10-year survival of 90% LVD due to viable tissue have worse prognosis than scars with annual

    Growing epidemiological evidence identifies key domains relevant to behavioral cardiology, including health behaviors, emotions, mental mindsets, stress management, social connectedness, and a sense of purpose. Each of these domains exists along a continuum, ranging from positive factors that promote health, to negative factors, which are pathophysiological. To date, there has been relatively little translation of this growing knowledge base into cardiology practice. Four initiatives are proposed to meet this challenge: 1) promulgating greater awareness of the potency of psychosocial risks factors; 2) overcoming a current "artificial divide" between conventional and psychosocial risk factors; 3) developing novel cost-effective interventions using Internet and mobile health applications, group-based counseling, and development of tiered-care behavioral management; and 4) in recognition that "one size does not fit all" with respect to behavioral interventions, developing specialists who can counsel patients in multidisciplinary fashion and use evidence-based approaches for promoting patient motivation and execution of health goals.

    We examined the interventions used by nurses to prevent pressure ulcers in 3 hospitals in south west Nigeria and perceived barriers to effective nursing pressure ulcer prevention interventions. One hundred ninety-three nurses were purposively selected from neurological, orthopedic, intensive care, and accident and emergency units of participating hospitals. Study sites were 3 teaching hospitals in south west Nigeria (Lagos State University Teaching Hospital, Lagos; University College Hospital, Ibadan; and Obafemi Awolowo Teaching Hospital Ile-Ife). Data were collected via a structured questionnaire designed for this study. It included 3 sections: demographic information, practices used for pressure ulcer prevention, and perceived barriers to prevention. Sections of the questionnaire that queried interventions and perceived barriers to pressure ulcer prevention were evaluated for face and content validity. Reliability was evaluated via internal consistency; the split half reliability was 0.82. Similar practices regarding pressure ulcer prevention were found across the 3 hospitals. The most commonly used intervention was patient repositioning every 2 hours; the least used intervention was completion of a validated pressure ulcer risk scale. Nurses described using interventions that have not proved effective for pressure ulcer prevention such as massaging bony prominences and application of talcum powder. Nurses identified 2 principal factors that act as barriers to successful prevention of pressure ulcers: inadequate manpower and inadequate supply of linens on the wards. Nurses use a combination of evidence-based interventions, along with interventions that have not proved effective for pressure ulcer prevention. We recommend development of national standards for pressure ulcer prevention in Nigeria that are based on current best evidence and consistent with current international guidelines.

    Nuclear cardiology has been an exciting new field of nuclear medicine. Few examples of the dynamism and excitement of nuclear medicine demonstrate this field's vitality in the way that nuclear cardiology does. Recent new developments in radiopharmaceuticals and instrumentation have established this field as an extremely useful clinical tool and provide a new dimension to the evaluation of a cardiac patient, more so being nonivasive in nature. An attempt has been made to focus the attention on some of the recent advances in nuclear cardiology with a special reference to its clinical application in the field of cardiology. Nuclear cardiology is the most important field of nuclear medicine which has shown most promising results and has opened a new horizon in the field of diagnostic noninvasive cardiac technique. Now it has come of age in concept, instrument development and clinical application. It is very rapidly growing into a subspeciality. (author)

    The management of non-ST segment elevation acute coronary syndromes (NSTEACS) remains an issue for mobidity, mortality, and an economic stake. The first aim of the study was to evaluate the additional value of the GRACE score for the compliance with the recommended times to coronary angiography in an hospital without interventional cardiology. We also analysed the in-hospital and 6-month mortality and the predictive factors of compliance for the coronarography delays. Retrospective monocenter cross-sectional study including consecutive patients with chest pain suggestive of a NSTEACS during 1 year. Data of the delay to coronarography were collected and GRACE score was calculated a posteriori. The time to perform coronary angiography was non-compliant in 49% of cases (27 patients out of 55). The calculation of the GRACE score would have allowed correcting the delay for two patients of our cohort. Clinical appreciation, troponin elevation, ECG modifications were associated with the delay compliance. Age <75 years predisposed to recommended delays. Renal failure and history of coronaropathy were significantly associated with non compliant delays. A non-compliant delay was significantly associated with higher mortality. In our experience, the knowledge of the GRACE score had little impact on the timing of coronary angiography. However, as a predictor of mid and long term mortality, GRACE score remains SCA ST+ useful to intensify surveillance of high-risk patients. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    The current applications of nuclear cardiology techniques are reviewed. Coronary artery disease is the most important and prevalent cardiovascular problem in most developed countries and also in Chile. Different approaches can be employed for its diagnosis and prognosis, as well as for risk stratification and preoperative evaluation. Myocardial infarction assessment and ischemia recognition with radionuclide perfusion images are also reviewed, including new protocols applying functional parameters addition. Viability detection after myocardial infarction or in patients with ischemic cardiomyopathy are discussed. Stress protocols with the use of exercise or pharmacological action for ischemia production, the diagnostic value of perfusion SPECT and the use of Thallium-201, Tc-99m-Sestamibi and metabolic images with Fluorine18-Fluordeoxyglucose are also mentioned (au)

    Nuclear medicine in cardiology was reviewed. Electrocardiogram is obtained from the ..gamma..-ray measurement of a tracer by a single detector, which enables a bedsidemonitoring. Resolution and sensitivity are high and nuclear stethoscope with a computer is applicable for a background treatment. Myocardium is imaged by /sup 201/Tl scintigraphy. Relative difference of the perfusion indicates the ischemia which gaives roughly the size and portion of myocardial infarction. For transient ischemia stress myocardial perfusion imaging (SMPI) is also used. sup(99m)Tc pyrophosphate provides a clear image for myocardial infarction. Angiocardiogram is obtained repeatedly, by a single administration, using an equilibrium method. An attempt of three-dimensional display by 7 pin hole collimator and positron CT are also discussed.

    To analyse the correlations between the eye lens dose estimates performed with dosimeters placed next to the eyes of paediatric interventional cardiologists working with a biplane system, the personal dose equivalent measured on the thorax and the patient dose. The eye lens dose was estimated in terms of H p (0.07) on a monthly basis, placing optically stimulated luminescence dosimeters (OSLDs) on goggles. The H p (0.07) personal dose equivalent was measured over aprons with whole-body OSLDs. Data on patient dose as recorded by the kerma-area product (P KA ) were collected using an automatic dose management system. The 2 paediatric cardiologists working in the facility were involved in the study, and 222 interventions in a 1-year period were evaluated. The ceiling-suspended screen was often disregarded during interventions. The annual eye lens doses estimated on goggles were 4.13±0.93 and 4.98±1.28mSv. Over the aprons, the doses obtained were 10.83±0.99 and 11.97±1.44mSv. The correlation between the goggles and the apron dose was R 2 =0.89, with a ratio of 0.38. The correlation with the patient dose was R 2 =0.40, with a ratio of 1.79μSvGy -1 cm -2 . The dose per procedure obtained over the aprons was 102±16μSv, and on goggles 40±9μSv. The eye lens dose normalized to P KA was 2.21±0.58μSvGy -1 cm -2 . Measurements of personal dose equivalent over the paediatric cardiologist's apron are useful to estimate eye lens dose levels if no radiation protection devices are typically used.

    Depression and anxiety disorders are the leading cause of sickness absence and long-term work incapacity in most developed countries. The present study aimed to carry out a systematic meta-review examining the effectiveness of workplace mental health interventions, defined as any intervention that a workplace may either initiate or facilitate that aims to prevent, treat or rehabilitate a worker with a diagnosis of depression, anxiety or both. Relevant reviews were identified via a detailed systematic search of academic and grey literature databases. All articles were subjected to a rigorous quality appraisal using the AMSTAR assessment. Of the 5179 articles identified, 140 studies met the inclusion criteria, of which 20 were deemed to be of moderate or high quality. Together, these reviews analysed 481 primary research studies. Moderate evidence was identified for two primary prevention interventions; enhancing employee control and promoting physical activity. Stronger evidence was found for CBT-based stress management although less evidence was found for other secondary prevention interventions, such as counselling. Strong evidence was also found against the routine use of debriefing following trauma. Tertiary interventions with a specific focus on work, such as exposure therapy and CBT-based and problem-focused return-to-work programmes, had a strong evidence base for improving symptomology and a moderate evidence base for improving occupational outcomes. Overall, these findings demonstrate there are empirically supported interventions that workplaces can utilize to aid in the prevention of common mental illness as well as facilitating the recovery of employees diagnosed with depression and/or anxiety.

  4. Evaluating the benefits of nuclear cardiology

    This paper reviews the role of nuclear cardiology in the context of health care evaluation and resource utilisation. Nuclear cardiology procedures are used to detect disease, to define the extent of disease, to predict the outcome of therapy and to monitor the response to treatment. The evaluation of effectiveness will depend on the role for which the tests are being used. The evaluation of diagnostic tests most commonly follows the five level Fineberg classification. I) Technical capacity; II) diagnostic accuracy; III) diagnostic impact; IV) therapeutic impact; V) patient outcome. Tests may succeed or fail at each of these hierarchical levels. In addition to the clinical impact which is evaluated, the appropriate use of health care resources has to be considered , i.e. the cost effectiveness of the investigation. For this the costs of diagnosis and treatment in the resources used, together with the direct cost on the patient and patient carers needs to be considered. In addition to these direct costs to the community and to the patient and the carers the secondary downstream costs and opportunity costs have to be taken into account. The common methods for assessing the costs and benefits include cost minimization, cost effectiveness, cost utility, and cost benefit studies. The advantage and appropriate use of these methods are reviewed. There are seven clinical methods for evaluating diagnostics tests in nuclear cardiology which are: I) Case reports; II) consensus studies; III) databases; IV) management impact studies; V)modeling techniques; VI) management impact studies; VII) randomized control trial. Each of these has a role with advantages and disadvantages which are reviewed. It is no long sufficient to investigate the usefulness of a diagnostic test used in nuclear cardiology in isolation but it as to be within the context of the health care system and the resource used

Few stepwise increases in the rate of procedures or medications were seen as determinants increased in acuity.Conclusion: Among these common MPDS complaint-based categories, the rates of advanced procedures and cardiac arrest medications were low. ALS medications were common in all categories and most determinants. Multiple determinants were rarely used and did not show higher rates of interventions with increasing acuity. Many MPDS determinants are of modest use to predict ALS intervention. [West J Emerg Med. 2011;12(1:19-29.

    The history of cardiology in Jamaica is conveniently considered in decades beginning in the 1950s. The decade of the 1950s was characterized by early descriptions of the pattern of cardiac disease in adults and children in Jamaica, the establishment of a cardiac clinic at the University Hospital of the West Indies and early cardiac surgical landmarks. Extensive preparatory experimental work in the canine laboratory with respect to cardiopulmonary bypass in the early to mid-1960s culminated in the successful completion of the first open heart surgical procedure in April, 1968. Cardiac catheterization was also increasingly developed in the decade of the 1960s. A highlight of the decade of the 1970s was the establishment of the Heart Foundation of Jamaica which began contributing greatly to preventive cardiology in Jamaica by providing a variety of programmes of prevention. In the decade of the 1980s, non-invasive cardiac diagnostic facilities in Jamaica were considerably enhanced by the introduction and development of echocardiography, treadmill exercise testing and ambulatory electrocardiography. In addition, the very important National Rheumatic Fever prevention programme was established. The cardiac catheterization laboratory was re-opened in the 1990s, thus allowing the performance of coronary arteriography in Jamaica for the first time, and interventional cardiology procedures soon followed. The Jamaica Foundation for Cardiac disease was also established in this decade. The vision for the new millennium of "A heart healthy Jamaica in the 21st century" is achievable, but will require appropriate emphasis on expanded preventive and curative cardiology programmes.

    Sharing deidentified patient-level research data presents immense opportunities to all stakeholders involved in cardiology research and practice. Sharing data encourages the use of existing data for knowledge generation to improve practice, while also allowing for validation of disseminated research. In this review, we discuss key initiatives and platforms that have helped to accelerate progress toward greater sharing of data. These efforts are being prompted by government, universities, philanthropic sponsors of research, major industry players, and collaborations among some of these entities. As data sharing becomes a more common expectation, policy changes will be required to encourage and assist data generators with the process of sharing the data they create. Patients also will need access to their own data and to be empowered to share those data with researchers. Although medicine still lags behind other fields in achieving data sharing's full potential, cardiology research has the potential to lead the way.

    Full Text Available Abstract Due to the limited supply of mental health services for Afro-Colombian victims of violence, a Common Elements Treatment Approach (CETA intervention has been implemented in the Colombian Pacific. Given the importance of improvement in mental health interventions for this population, it is necessary to characterize this process. This article seeks to describe the implementation of CETA for Afro-Colombian victims of violence in Buenaventura and Quibdó, Colombia through case studieswith individual in-depth interviews with Lay Psychosocial Community Workers (LPCW, supervisors, and coordinators responsible for implementing CETA. From this six core categories were obtained: 1. Effect of armed conflict and poverty 2. Trauma severity 3. Perceived changes with CETA 4. Characteristics and LPCW’s performance 5. Afro-Colombian culturalapproach and 6. Strategies to promote users’ well-being.Colombian Pacific’s scenario implies several factors, such as the active armed conflict, economic crisis, and lack of mental health care resources, affecting the implementation process and the intervention effects. This implies the need to establish and strengthen partnerships between institutions in order to administer necessary mental health care for victims of violence in the Colombian Pacific.

    The findings of many new cardiology clinical trials over the last year have been published or presented at major international meetings. This paper aims to describe and place in context a summary of the key clinical trials in cardiology presented between January and December 2016. The authors reviewed clinical trials presented at major cardiology conferences during 2016 including the American College of Cardiology (ACC), European Association for Percutaneous Cardiovascular Interventions (EuroPCR), European Society of Cardiology (ESC), European Association for the Study of Diabetes (EASD), Transcatheter Cardiovascular Therapeutics (TCT), and the American Heart Association (AHA). Selection criteria were trials with a broad relevance to the cardiology community and those with potential to change current practice. A total of 57 key cardiology clinical trials were identified for inclusion. Here we describe and place in clinical context the key findings of new data relating to interventional and structural cardiology including delayed stenting following primary angioplasty, contrast-induced nephropathy, management of jailed wires, optimal duration of dual antiplatelet therapy (DAPT), stenting vs bypass for left main disease, new generation stents (BioFreedom, Orsiro, Absorb), transcatheter aortic valve implantation (Edwards Sapien XT, transcatheter embolic protection), and closure devices (Watchman, Amplatzer). New preventative cardiology data include trials of bariatric surgery, empagliflozin, liraglutide, semaglutide, PCSK9 inhibitors (evolocumab and alirocumab), and inclisiran. Antiplatelet therapy trials include platelet function monitoring and ticagrelor vs clopidogrel for peripheral vascular disease. New data are also presented in fields of heart failure (sacubitril/valsartan, aliskiren, spironolactone), atrial fibrillation (rivaroxaban in patients undergoing coronary intervention, edoxaban in DC cardioversion), cardiac devices (implantable cardioverter

    Full Text Available Aim: To create sustained improvements in medical students’ critical thinking skills through short teaching interventions in pharmacology. Method: The ability to make professional decisions was assessed by providing year-4 medical students at a UK medical school with a novel medical scenario (antenatal pertussis vaccination. Forty-seven students in the 2012 cohort acted as a pretest group, answering a questionnaire on this novel scenario. To improve professional decision-making skills, 48 students from the 2013 cohort were introduced to three commonly used medications, through tutor-led 40-min teaching interventions, among six small groups using a structured presentation of evidence-based medicine and ethical considerations. Student members then volunteered to peer-teach on a further three medications. After a gap of 8 weeks, this cohort (post-test group was assessed for professional decision-making skills using the pretest questionnaire, and differences in the 2-year groups analysed. Results: Students enjoyed presenting on medications to their peers but had difficulty interpreting studies and discussing ethical dimensions; this was improved by contextualising information via patient scenarios. After 8 weeks, most students did not show enhanced clinical curiosity, a desire to understand evidence, or ethical questioning when presented with a novel medical scenario compared to the previous year group who had not had the intervention. Students expressed a high degree of trust in guidelines and expert tutors and felt that responsibility for their own actions lay with these bodies. Conclusion: Short teaching interventions in pharmacology did not lead to sustained improvements in their critical thinking skills in enhancing professional practice. It appears that students require earlier and more frequent exposure to these skills in their medical training.

    Following the Safe and Sustainable review of Paediatric Services in 2012/2013, National Health Service England recommended that local paediatric cardiology services should be provided by specially trained paediatricians with expertise in cardiology in all non-specialist hospitals. To understand the variation in local paediatric cardiology services provided across district general hospitals in the United Kingdom. An internet-based questionnaire was sent out via the Paediatrician with Expertise in Cardiology Special Interest Group and the Neonatologists with Interest in Cardiology and Haemodynamics contact databases and the National Health Service directory. Non-responders were followed-up via telephone. The response rate was 80% (141 of 177 hospitals), and paediatricians with expertise in cardiology were available in 68% of those. Local cardiology clinics led by paediatricians with expertise in cardiology were provided in 96 hospitals (68%), whereas specialist outreach clinics were held in 123 centres (87%). A total of 11 hospitals provided neither specialist outreach clinics nor any local cardiology clinics led by paediatricians with expertise in cardiology. Paediatric echocardiography services were provided in 83% of the hospitals, 12-lead electrocardiogram in 96%, Holter electrocardiogram in 91%, and exercise testing in only 47% of the responding hospitals. Telemedicine facilities were established in only 52% of the centres, where sharing echocardiogram images via picture archiving and communication system was used most commonly. There has been a substantial increase in the availability of paediatricians with expertise in cardiology since 2008. Most of the hospitals are well-supported by specialist cardiology centres via outreach clinics; however, there remains significant variation in the local paediatric cardiology services provided across district general hospitals in the United Kingdom.

The Pediatric Cardiology Fellowship Boot Camp (PCBC) at Boston Children's Hospital was designed to provide incoming fellows with an intensive exposure to congenital cardiac pathology and a broad overview of major areas of paediatric cardiology practice. The PCBC curriculum was designed by core faculty in cardiac pathology, echocardiography, electrophysiology, interventional cardiology, exercise physiology, and cardiac intensive care. Individual faculty contributed learning objectives, which were refined by fellowship directors and used to build a programme of didactics, hands-on/simulation-based activities, and self-guided learning opportunities. A total of 16 incoming fellows participated in the 4-week boot camp, with no concurrent clinical responsibilities, over 2 years. On the basis of pre- and post-PCBC surveys, 80% of trainees strongly agreed that they felt more prepared for clinical responsibilities, and a similar percentage felt that PCBC should be offered to future incoming fellows. Fellows showed significant increase in their confidence in all specific knowledge and skills related to the learning objectives. Fellows rated hands-on learning experiences and simulation-based exercises most highly. We describe a novel 4-week-long boot camp designed to expose incoming paediatric cardiology fellows to the broad spectrum of knowledge and skills required for the practice of paediatric cardiology. The experience increased trainee confidence and sense of preparedness to begin fellowship-related responsibilities. Given that highly interactive activities were rated most highly, boot camps in paediatric cardiology should strongly emphasise these elements.

  16. Geriatric Cardiology: An Emerging Discipline.

    Given changing demographics, patients with cardiovascular (CV) disease in developed countries are now older and more complex than even a decade ago. This trend is expected to continue into the foreseeable future; accordingly, cardiologists are encountering patients with a greater number of comorbid illnesses as well as "geriatric conditions," such as cognitive impairment and frailty, which complicate management and influence outcomes. Simultaneously, technological advances have widened the therapeutic options available for patients, including those with the most advanced CV disease. In the setting of these changes, geriatric cardiology has recently emerged as a discipline that aims to adapt principles from geriatric medicine to everyday cardiology practice. Accordingly, the tasks of a "geriatric cardiologist" may include both traditional evidence-based CV management plus comprehensive geriatric assessment, medication reduction, team-based coordination of care, and explicit incorporation of patient goals into management. Given that the field is still in its relative infancy, the training pathways and structure of clinical programs in geriatric cardiology are still being delineated. In this review, we highlight the rationale behind geriatric cardiology as a discipline, several current approaches by geriatric cardiology programs, and future directions for the field.

    2008-01-01

    Nuclear cardiology is an essential part of functional, non-invasive, cardiac imaging. Significant advances have been made in nuclear cardiology since planar (201)thallium ((201)TI) scintigraphy was introduced for the evaluation of left ventricular (LV) perfusion nearly 40 years ago. The use...... of nuclear cardiology has been steadily increasing over the last 20 years with important steps being the introduction of (99m)technetium- ((99m)Tc)-labelled perfusion radiotracers, the change from only planar to now much more single photon emission computed tomography (SPECT) and positron emission tomography...... (PET), electrocardiogram gating of nuclear perfusion imaging, and finally introducing nuclear hybrid imaging using either SPECT or PET together with either computed tomography or magnetic resonance imaging. The indications have extended from nearly only coronary artery diseases to several non...

    Compound congenital cardiac anomalies refer to two or more congenital cardiovascular defects coexisting in the same patient. Transcatheter intervention for compound congenital cardiac anomalies has got satisfactory results in recent years. However, the percutaneous closure procedure used for compound congenital cardiac defects does not mean the simple addition of single interventional technique. Clinically, it needs more specialist expertise to deal with such complex defects. This chapter will briefly describe the pathophysiology and clinical features of the following compound congenital cardiac anomalies: the ventricular septal defect (VSD) with coexistence of atrial septal defect (ASD), patent ductus arteriosus (PDA) or pulmonary valve stenosis (PS), the ASD coexistence of PDA, PS or mitral stenosis (Lutembacher's syndrome), and coarctation of aorta compound with PDA. The indications and contraindications, the therapeutic principles, the matters needing attention, the postoperative management, the judgment of curative effect, etc. of using transcatheter for the treatment of such compound anomalies will also be discussed.

    The transition from residency to subspecialty fellowship in a procedurally driven field such as pediatric cardiology is challenging for trainees. We describe and assess the educational value of a pediatric cardiology "boot camp" educational tool designed to help prepare trainees for cardiology fellowship. A two-day intensive training program was provided for pediatric cardiology fellows in July 2015 at a large fellowship training program. Hands-on experiences and simulations were provided in: anatomy, auscultation, echocardiography, catheterization, cardiovascular intensive care (CVICU), electrophysiology (EP), heart failure, and cardiac surgery. Knowledge-based exams as well as surveys were completed by each participant pre-training and post-training. Pre- and post-exam results were compared via paired t tests, and survey results were compared via Wilcoxon rank sum. A total of eight participants were included. After boot camp, there was a significant improvement between pre- and post-exam scores (PRE 54 ± 9 % vs. POST 85 ± 8 %; p ≤ 0.001). On pre-training survey, the most common concerns about starting fellowship included: CVICU emergencies, technical aspects of the catheterization/EP labs, using temporary and permanent pacemakers/implantable cardiac defibrillators (ICDs), and ECG interpretation. Comparing pre- and post-surveys, there was a statistically significant improvement in the participants comfort level in 33 of 36 (92 %) areas of assessment. All participants (8/8, 100 %) strongly agreed that the boot camp was a valuable learning experience and helped to alleviate anxieties about the start of fellowship. A pediatric cardiology boot camp experience at the start of cardiology fellowship can provide a strong foundation and serve as an educational springboard for pediatric cardiology fellows.

    Nuclear Cardiology is a widely available and a widely accepted tool for diagnosis and management of coronary artery disease both in the US and in Europe. Although the most common indications for nuclear studies are similar in the US and Europe, different social and economical environments may affect the practice of Nuclear Cardiology. The aim of this paper is to identify key issues and to provide some information on the similarities and differences which characterize the practice of Nuclear Cardiology in the US and Europe. This paper takes into account the training requirements, the relationships between different professional societies, the accessibility, the choice of imaging protocols, tracers and stressors, the impact of managed care and the role of cardiologists, nuclear physicians and technologists in nuclear labs. The economical differences which may affect the field of high technology, imply a wide range of variability concerning the availability of nuclear cardiology studies in different countries (1:1/10). Moreover the legislation which regulates the practice of nuclear medicine may differ from country. Thus in our opinion there are several important factors both in the US and Europe limiting the development of nuclear cardiology independently of its intrinsic clinical value

    The results are presented on the «current situation of the organisation, resources and activity in paediatric cardiology in Spain». It was promoted by the Spanish Society of Paediatric Cardiology and Congenital Heart disease. An analysis was carried out on the results obtained from a specifically designed questionnaire, prepared by the Spanish Society of Paediatric Cardiology and Congenital Heart disease, that was sent to all hospitals around the country that offer the speciality of paediatric cardiology. A total of 86 questionnaires were obtained, including 14 hospitals that perform cardiac surgery on children. A total of 190 paediatric cardiology consultants, 40 cardiac surgeons, and 27 middle grade doctors performing their paediatric residency (MIR program) were identified. All hospitals had adequate equipment to perform an optimal initial evaluation of any child with a possible cardiac abnormality, but only tertiary centres could perform complex diagnostic procedures, interventional cardiology, and cardiac surgery. In almost all units around the country, paediatric cardiology consultants were responsible for outpatient clinics and hospital admissions, whereas foetal cardiology units were still mainly managed by obstetricians. The number of diagnostic and therapeutic procedures was similar to those reported in the first survey, except for a slight decrease in the total number of closed cardiac surgery procedures, and a proportional increase in the number of therapeutic catheterisations. Paediatric Cardiology in Spain is performed by paediatric cardiology consultants that were trained initially as general paediatricians, and then completed a paediatric cardiology training period. Almost all units have adequate means for diagnosis and treatment. Efforts should be directed to create a national registry that would not only allow a prospective quantification of diagnostic and therapeutic procedures, but also focus on their clinical outcomes.

    Nuclear cardiology is one of the major fields of nuclear medicine practice. Myocardial perfusion studies using single-photon emission computed tomography (SPECT) have played a crucial role in the management of coronary artery diseases. Positron emission tomography (PET) has also been considered an important tool for the assessment of myocardial viability and perfusion. However, the recent development of computed tomography (CT)/magnetic resonance imaging (MRI) technologies and growing concerns about the radiation exposure of patients remain serious challenges for nuclear cardiology. In response to these challenges, remarkable achievements and improvements are currently in progress in the field of myocardial perfusion imaging regarding the applicable software and hardware. Additionally, myocardial perfusion positron emission tomography (PET) is receiving increasing attention owing to its unique capability of absolute myocardial blood flow estimation. An F-18-labeled perfusion agent for PET is under clinical trial with promising interim results. The applications of F-18 fluorodeoxyglucose (FDG) and F-18 sodium fluoride (NaF) to cardiovascular diseases have revealed details on the basic pathophysiology of ischemic heart diseases. PET/MRI seems to be particularly promising for nuclear cardiology in the future. Restrictive diseases, such as cardiac sarcoidosis and amyloidosis, are effectively evaluated using a variety of nuclear imaging tools. Considering these advances, the current challenges of nuclear cardiology will become opportunities if more collaborative efforts are devoted to this exciting field of nuclear medicine

    Cardiovascular diseases are the deadliest diseases worldwide, with 17.3 million deaths in 2008 alone. Among them, heart-related deaths are of the utmost relevance; a fact easily proven by the 7.25 million deaths caused by ischemic heart disease alone in that year. The latest advances in smartphones and mHealth have been used in the creation of thousands of medical apps related to cardiology, which can help to reduce these mortality rates. The aim of this paper is to study the literature on mobile systems and applications currently available, as well as the existing apps related to cardiology from the leading app stores and to then classify the results to see what is available and what is missing, focusing particularly on commercial apps. Two reviews have been developed. One is a literature review of mobile systems and applications, retrieved from several databases and systems such as Scopus, PubMed, IEEE Xplore, and Web of Knowledge. The other is a review of mobile apps in the leading app stores, Google play for Android and Apple's App Store for iOS. Search queries up to May 2013 located 406 papers and 710 apps related to cardiology and heart disease. The most researched section in the literature associated with cardiology is related to mobile heart (and vital signs) monitoring systems and the methods involved in the classification of heart signs in order to detect abnormal functions. Other systems with a significant number of papers are mobile cardiac rehabilitation systems, blood pressure measurement, and systems for the detection of heart failure. The majority of apps for cardiology are heart monitors and medical calculators. Other categories with a high number of apps are those for ECG education and interpretation, cardiology news and journals, blood pressure tracking, heart rate monitoring using an external device, and CPR instruction. There are very few guides on cardiac rehabilitation and apps for the management of the cardiac condition, and there were no

    Hundreds of validated evidence-based intervention programs (EBIP) aim to improve families' well-being; however, most are not broadly adopted. As an alternative diffusion strategy, we created wellness centers to reach families' everyday lives with a prevention framework. At two wellness centers, one in a middle-class neighborhood and one in a low-income neighborhood, popular local activity leaders (instructors of martial arts, yoga, sports, music, dancing, Zumba), and motivated parents were trained to be Family Mentors. Trainings focused on a framework that taught synthesized, foundational prevention science theory, practice elements, and principles, applied to specific content areas (parenting, social skills, and obesity). Family Mentors were then allowed to adapt scripts and activities based on their cultural experiences but were closely monitored and supervised over time. The framework was implemented in a range of activities (summer camps, coaching) aimed at improving social, emotional, and behavioral outcomes. Successes and challenges are discussed for (a) engaging parents and communities; (b) identifying and training Family Mentors to promote children and families' well-being; and (c) gathering data for supervision, outcome evaluation, and continuous quality improvement. To broadly diffuse prevention to families, far more experimentation is needed with alternative and engaging implementation strategies that are enhanced with knowledge harvested from researchers' past 30 years of experience creating EBIP. One strategy is to train local parents and popular activity leaders in applying robust prevention science theory, common practice elements, and principles of EBIP. More systematic evaluation of such innovations is needed.

    Background Transcatheter aortic valve implantation (TAVI) continues to gain popularity in the management of patients with severe aortic stenosis (SAS). Distribution of resources to maximise appropriate use remains a priority. Design & methods To determine the current perceptions and behaviours regarding SAS patient management, an 18-point multiple-choice questionnaire was distributed to European Society of Cardiology (ESC) Council for Cardiology Practice (CCP) e-journal and/or electronic newsletter subscribers. Respondents to all questions were considered. Sub-analyses based on respondent age, practice setting and geographical location were performed. Results Of 1245 full respondents, 41.5% were aged ≥ 51 years, 22.7% were aged 41-50 years and 35.8% were aged ≤ 40 years. The majority were located in Europe (77.5%), followed by Asia/Oceania (11.6%), America (7.6%) and Africa (3.4%). In-hospital and out-of-hospital cardiologists accounted for 57.4% of and 28.5% of the sample, respectively, with the remainder being general practitioners/other. The majority of respondents (70.1%) claimed to diagnose between one and five cases of SAS per month. Free access to TAVI was reported by 41.2%, being less common for those aged ≤ 40 years (32.7%; p < 0.001), those located in Asia/Oceania, America and Africa (20.1%, 18.1% and 2.4%, respectively; p < 0.01 in each case) and in-hospital compared to out-of-hospital cardiologists (35.7% vs. 54.5%, respectively; p < 0.001). The most common reason for not referring a patient for an aortic valve intervention was assessment that the patient was high risk/non-operable (55.5%), followed by short life expectancy (30.5%). The most common reason for referring a patient for TAVI over surgical replacement was surgical risk score (56.9%). The most commonly perceived main complication of TAVI was stroke (28.9%), while the most frequently selected main benefit was improvement in quality of life (37.2%). A high

    Introduction Paediatricians with Expertise in Cardiology assess children with a full history, examination, and often perform an echocardiogram. A minority are then referred to an outreach clinic run jointly with a visiting paediatric cardiologist. The accuracy of the echocardiography diagnosis made by the Paediatrician with Expertise in Cardiology is unknown. Materials and methods We conducted a retrospective review of clinic letters for children seen in the outreach clinic for the first time between March, 2004 and March, 2011. Children with CHD diagnosed antenatally or elsewhere were excluded. We recorded the echocardiography diagnosis made by the paediatric cardiologist and previously by the Paediatrician with Expertise in Cardiology. The Paediatrician with Expertise in Cardiology referred 317/3145 (10%) children seen in the local cardiac clinics to the outreach clinic over this period, and among them 296 were eligible for inclusion. Their median age was 1.5 years (range 1 month-15.1 years). For 244 (82%) children, there was complete diagnostic agreement between the Paediatrician with Expertise in Cardiology and the paediatric cardiologist. For 29 (10%) children, the main diagnosis was identical with additional findings made by the paediatric cardiologist. The abnormality had resolved in 17 (6%) cases by the time of clinic attendance. In six (2%) patients, the paediatric cardiologist made a different diagnosis. In total, 138 (47%) patients underwent a surgical or catheter intervention. Discussion Paediatricians with Expertise in Cardiology can make accurate diagnoses of CHD in children referred to their clinics. This can allow effective triage of children attending the outreach clinic, making best use of limited specialist resources.

    Although pediatrician-reported relevance of Canadian cardiology-specific objectives has been studied, similar data are not available for the 2016 American Board of Pediatrics (ABP) cardiology-specific objectives. This study asked Kentucky trainees, pediatricians, and pediatric cardiologists to identify "most important" content within these objectives. This cross-sectional study used an original, online survey instrument based on the 2016 ABP cardiology-specific objectives. We collected quantitative data (numerical indications of importance) and qualitative data (open-ended replies regarding missing content and difficulty in teaching and learning). Respondents indicated the top two choices of most important items within eight content areas. Descriptive statistics (frequencies and percentages) and chi-square analysis were calculated. Content within categories was organized using naturally occurring "clusters" and "gaps" in scores. Common themes among open-ended qualitative responses were identified using Pandit's version of Glaser and Strauss Grounded theory (constant comparison). Of the 136 respondents, 23 (17%) were residents, 15 (11%) fellows, 85 (62%) pediatricians, and 13 (10%) pediatric cardiologists. Of attendings, 80% reported faculty/gratis faculty status. Naturally occurring clusters in respondent-designated importance resulted in ≤3 "most selected" objectives per content area. Objectives in "most selected" content pertained to initial diagnosis (recognition of abnormality/disease) (n = 16), possible emergent/urgent intervention required (n = 14), building a differential (n = 8), and planning a workup (n = 4). Conversely, themes for "least selected" content included comanagement with subspecialist (n = 15), knowledge useful in patient-family communication (n = 9), knowledge that can be referenced (as needed) (n = 7), and longitudinal/follow-up concerns (n = 5). This study demonstrated the utility of an online survey

    This Consensus Document is the first of two reports summarizing the views of an expert panel organized by the European Association of Percutaneous Cardiovascular Interventions (EAPCI) on the clinical use of intracoronary imaging including intravascular ultrasound (IVUS) and optical coherence tomography (OCT). The first document appraises the role of intracoronary imaging to guide percutaneous coronary interventions (PCIs) in clinical practice. Current evidence regarding the impact of intracoronary imaging guidance on cardiovascular outcomes is summarized, and patients or lesions most likely to derive clinical benefit from an imaging-guided intervention are identified. The relevance of the use of IVUS or OCT prior to PCI for optimizing stent sizing (stent length and diameter) and planning the procedural strategy is discussed. Regarding post-implantation imaging, the consensus group recommends key parameters that characterize an optimal PCI result and provides cut-offs to guide corrective measures and optimize the stenting result. Moreover, routine performance of intracoronary imaging in patients with stent failure (restenosis or stent thrombosis) is recommended. Finally, strengths and limitations of IVUS and OCT for guiding PCI and assessing stent failures and areas that warrant further research are critically discussed.

    The rigorous cardiovascular (CV) demands of sport, combined with training-related cardiac adaptations, render the athlete a truly unique CV patient and sports cardiology a truly unique discipline. Cardiologists are advised to adopt a systematic approach to the CV evaluation of athletes, taking into consideration the individual sports culture, sports-specific CV demands, CV adaptations and their appearance on cardiac testing, any existing or potential interaction of the heart with the internal and external sports environment, short- and long-term CV risks, and potential effect of performance-enhancing agents and antidoping regulations. This article outlines the systematic approach, provides a detailed example, and outlines contemporary sports cardiology core competencies. Copyright © 2015 Elsevier Inc. All rights reserved.

    Cardiology fellows can be exposed to high radiation levels during procedures. Proper radiation training and implementation of safety procedures is of critical importance in lowering physician health risks associated with radiation exposure. Participants were cardiology fellows in the United States (n = 2,545) who were contacted by e-mail to complete an anonymous survey regarding the knowledge and practice of radiation protection during catheterization laboratory procedures. An on-line survey engine, SurveyMonkey, was used to distribute and collect the results of the 10-question survey. The response rate was 10.5%. Of the 267 respondents, 82% had undergone formal radiation safety training. Only 58% of the fellows were aware of their hospital's pregnancy radiation policy and 60% knew how to contact the hospital's radiation safety officer. Although 52% of the fellows always wore a dosimeter, 81% did not know their level of radiation exposure in the previous year and only 74% of fellows knew the safe levels of radiation exposure. The fellows who had received formal training were more likely to be aware of their pregnancy policy, to know the contact information of their radiation safety officer, to be aware of the safe levels of radiation exposure, to use dosimeters and RadPad consistently, and to know their own level of radiation exposure in the previous year. In conclusion, cardiology fellows have not been adequately educated about radiation safety. A concerted effort directed at physician safety in the workplace from the regulatory committees overseeing cardiology fellowships should be encouraged. Published by Elsevier Inc.

    The American College of Cardiology, Society for Cardiovascular Angiography and Interventions, Society of Thoracic Surgeons, and American Association for Thoracic Surgery, along with key specialty and subspecialty societies, have completed a 2-part revision of the appropriate use criteria (AUC) for coronary revascularization. In prior coronary revascularization AUC documents, indications for revascularization in acute coronary syndromes and stable ischemic heart disease (SIHD) were combined into 1 document. To address the expanding clinical indications for coronary revascularization, and to align the subject matter with the most current American College of Cardiology/American Heart Association guidelines, the new AUC for coronary artery revascularization were separated into 2 documents addressing SIHD and acute coronary syndromes individually. This document presents the AUC for SIHD.Clinical scenarios were developed to mimic patient presentations encountered in everyday practice. These scenarios included information on symptom status; risk level as assessed by noninvasive testing; coronary disease burden; and, in some scenarios, fractional flow reserve testing, presence or absence of diabetes, and SYNTAX score. This update provides a reassessment of clinical scenarios that the writing group felt were affected by significant changes in the medical literature or gaps from prior criteria. The methodology used in this update is similar to the initial document but employs the recent modifications in the methods for developing AUC, most notably, alterations in the nomenclature for appropriate use categorization.A separate, independent rating panel scored the clinical scenarios on a scale of 1 to 9. Scores of 7 to 9 indicate that revascularization is considered appropriate for the clinical scenario presented.

    Fungi are the second most abundant type of human pathogens. Invasive fungal pathogens are leading causes of life-threatening infections in clinical settings. Toxicity to the host and drug-resistance are two major deleterious issues associated with existing antifungal agents. Increasing a host's tolerance and/or immunity to fungal pathogens has potential to alleviate these problems. A host's tolerance may be improved by modulating the immune system such that it responds more rapidly and robustly in all facets, ranging from the recognition of pathogens to their clearance from the host. An understanding of biological processes and genes that are perturbed during attempted fungal exposure, colonization, and/or invasion will help guide the identification of endogenous immunomodulators and/or small molecules that activate host-immune responses such as specialized adjuvants. In this study, we present computational techniques and approaches using publicly available transcriptional data sets, to predict immunomodulators that may act against multiple fungal pathogens. Our study analyzed data sets derived from host cells exposed to five fungal pathogens, namely, Alternaria alternata, Aspergillus fumigatus, Candida albicans, Pneumocystis jirovecii, and Stachybotrys chartarum. We observed statistically significant associations between host responses to A. fumigatus and C. albicans. Our analysis identified biological processes that were consistently perturbed by these two pathogens. These processes contained both immune response-inducing genes such as MALT1, SERPINE1, ICAM1, and IL8, and immune response-repressing genes such as DUSP8, DUSP6, and SPRED2. We hypothesize that these genes belong to a pool of common immunomodulators that can potentially be activated or suppressed (agonized or antagonized) in order to render the host more tolerant to infections caused by A. fumigatus and C. albicans. Our computational approaches and methodologies described here can now be applied to

Both nuclear cardiology and other cardiac imaging have its own advantage and disadvantage in the diagnostic of coronary artery disease. And the relationship of them is complementary but not instead of each other. Nuclear cardiology provides a one-stop shop for diagnosis, risk stratification, and management of coronary artery disease. Nuclear cardiology plays a very important role in the diagnostic of coronary artery disease in early stage in the special group of people. (authors)

    World Health Organisation (WHO) estimates that about half of all medicines are inappropriately prescribed, dispensed and sold and about half of all patients fail to take their medicines properly. The overall objective of the study was improving use of medicines in the community by creating awareness among different target groups. It was a pre-post comparison of intervention implemented at the community level in purposively selected Bhaktapur District of Kathmandu Valley, Nepal. The study was conducted in the private schools of the study district. Twelve schools were randomly selected. Thereafter, students from 6-9 grades were listed from the selected schools. Then 15% of the total students in each grade were randomly selected to get six students from each grade of the each school, totaling 288 students. The households of the selected students served as the sample households for the study. Thus, there were 288 households sampled for the study. The intervention and the targeted intermediary groups consisted of a. training of schools teachers b. training of journalists c. interactive discussions of trained school teachers with school children using key messages and c. communication of key messages through the local F.M. radio, newspaper/magazine. There was a significant increase in correct knowledge on action of antibiotics and excellent knowledge on the methods of administration of antibiotics of households after the intervention. Similarly, there was a significant increase in knowledge on cough as a disease and a significant decrease in the use of cough medicines after intervention. There was also a significant increase in excellent knowledge on the sources of vitamins and a significant decrease in the use of vitamin/tonics after the intervention. The participation of intermediary groups eg. school teachers, journalists and school children in the implementation of intervention were successful. The groups have fulfilled the commitments in implementing the plan of

    Accurate cardiovascular imaging is essential for the successful management of patients with congenital heart disease (CHD). Echocardiography and angiography have been for long time the most important imaging modalities in pediatric cardiology, but nuclear medicine has contributed in many situations to the comprehension of physiological consequences of CHD, quantifying pulmonary blood flow symmetry or right-to-left shunting. In recent times, remarkable improvements in imaging equipments, particularly in multidetector computed tomography and magnetic resonance imaging, have led to the progressive integration of high resolution modalities in the clinical workup of children affected by CHD, reducing the role of diagnostic angiography. Technology has seen a parallel evolution in the field of nuclear medicine, with the advent of hybrid machines, as SPECT/CT and PET/CT scanners. Improved detectors, hugely increased computing power, and new reconstruction algorithms allow for a significant reduction of the injected dose, with a parallel relevant decrease in radiation exposure. Nuclear medicine retains its distinctive capability of exploring at the tissue level many functional aspects of CHD in a safe and reproducible way. The lack of invasiveness, the limited need for sedation, the low radiation burden, and the insensitivity to body habitus variations make nuclear medicine an ideal complement of echocardiography. This is particularly true during the follow-up of patients with CHD, whose increasing survival represent a great medical success and a challenge for the health system in the next decades. Metabolic imaging using 18 FDG PET/CT has expanded its role in the management of infection and inflammation in adult patients, particularly in cardiology. The same expansion is observed in pediatric cardiology, with an increasing rate of studies on the use of FDG PET for the evaluation of children with vasculitis, suspected valvular infection or infected prosthetic devices.

    Treadmill test combined with myocardial perfusion scintigraphy (MPS) is a commonly used technique in the assessment of coronary artery disease. However there are a group of patients who may not be able to undergo treadmill tests. Patients with underlying conditions like neuromuscular disease, musculoskeletal disorder, heart failure and end-stage renal disease (ESRD) on renal dialysis would find it difficult to perform exercise on a treadmill or bicycle ergometer. These conditions prevent them from performing adequate exercise. Such patients would benefit from pharmacological stress procedures combined with MPS. Nuclear medicine departments use various pharmacological agents while performing stress tests on cardiac patients. The most commonly used pharmacological agents for cardiac stress are coronary vasodilators and catecholamines. In addition to these agents, adjuvant use of nitrates and atropine is also a common practice in nuclear cardiology. This review addresses various physiological and pharmacological properties of the commonly used pharmacological stress agents in MPS and critically analyses their advantages and disadvantages, as well as their safety and efficacy.

    Objective: To contrast the level of radiation doses of Lead protective clothing both inside and outside in different parts of the body of the first and second operators and touring nurse in common endovascular and non-vascular interventional diagnosis and treatment. Methods: We choose the common endovascular interventional diagnosis and treatment in the head, thorax, abdomen, such as Cerebral angiography, Coronary angiography, Transcatheter arterial chemoembolization and non-vascular interventional diagnosis and treatment such as Endoscopic Retrograde Cholangio-Pancreatography and Percutaneous transhepatic cholangial drainage as experiment objects. Put the thermoluminescence dosimeter on the different spots of Lead protective clothing of subjects (Inside and outside the lead cap and the lead collar, inside and outside of the lead protective clothing in chest and abdomen, left upper arm outside of lead protective clothing, back of the left hand) and X-ray machine outgoing port when the operation was going on. After that, measure the thermoluminescence dosimeter, calculate and analyze exposure doses inside and outside of the lead protective clothing. Results: The skin doses of operators in different types of interventional diagnosis and treatment are listed in Table 1to Table 4; exposure doses of touring nurses are very low; the doses of X-ray machine outgoing port are mostly over the measuring range. Conclusion: The protection of Lead clothes plays a significant role in these two types of interventional diagnosis and treatment based on the conclusion that the dose of inside of Lead clothes is less than that of outside. We should enhance the operators' protection and administration in the process of intervention and arise the conscious of self-protection, to avoid the unnecessary radiation exposure. (authors)

    The worldwide spread of smartphones has radically changed the habits of human life, allowing a 24/7 connection with other people. These changes have involved also Medicine with smartphones being able to simplify the clinical practice of physicians. The development of new external devices that can be connected to smartphones has further increased their use with mobile phones converted in portable electrocardiogram or echocardiogram machines. This extraordinary technological improvement seems to be partly in conflict with the classical tools available for the cardiologist, such as the "old" stethoscope that in 2016 had its 200th anniversary. This article focuses on the smartphone as a new tool available for the physicians, describing the most important potential uses and reporting an analysis of pros and cons of the smart-cardiology.

    Few data exist on internal medicine trainees' selection of cardiology training, although this is important for meeting future cardiology workforce needs. To discover trainees' professional development preferences and perceptions of cardiology, and their relationship to trainees' career choice. We surveyed trainees to discover their professional development preferences and perceptions of cardiology and the influence of those perceptions and preferences on the trainees' career choices. Participants rated 38 professional development needs and 19 perceptions of cardiology. Data collection took place from February 2009, through January 2010. Data analysis was conducted from May 2017 to December 2017. Multivariable models were used to determine the association of demographics and survey responses with prospective career choice. A total of 4850 trainees were contacted, and 1123 trainees (of whom 625 [55.7%] were men) in 198 residency programs completed surveys (23.1% response; mean [SD] age, 29.4 [3.5] years). Principal component analysis of survey responses resulted in 8-factor and 6-factor models. Professional development preferences in descending order of significance were stable hours, family friendliness, female friendliness, the availability of positive role models, financial benefits, professional challenges, patient focus, and the opportunity to have a stimulating career. The top perceptions of cardiology in descending order of significance were adverse job conditions, interference with family life, and a lack of diversity. Women and future noncardiologists valued work-life balance more highly and had more negative perceptions of cardiology than men or future cardiologists, who emphasized the professional advantages available in cardiology. Professional development factors and cardiology perceptions were strongly associated with a decision to pursue or avoid a career in cardiology in both men and women.

    Full Text Available BACKGROUND: Terminology and Lexicography have been especially addressed to the Allied Health Sciences regarding discussion of case reports or concerning publication of scientific articles. The knowledge of Human Anatomy enables the understanding of medical terms and the refinement of Medical Terminology makes possible a better anatomicomedical communication in a highly technical level. Most of the scientific publications in both Anatomy and Medicine are found only in English and most of dictionaries or search resources available do not have specificity enough to explain anatomicomedical, terminological, or lexicographical occurrences. OBJECTIVE: To design and produce a multilingual terminological dictionary (Latim-English-Portuguese-Spanish containing a list of English anatomicomedical terms in common usage in cardiology subspecialties addressed to medical students and professionals, to other allied health sciences professionals, and to translators working in this specific field. METHODS: Terms, semantical and grammatical components were selected to compose an anatomicocardiological corpus. The adequacy to the thematic terminological research requests and the translation reliability level will be settled from the terminology specificity in contrast to the semantics, as well as from a peer survey of the main terms used by national and international experts in specialized journals, Internet sites, and from text-books on Anatomy and Cardiology. The inclusion criteria will be the terms included in the English, Portuguese, and Spanish Terminologia Anatomica - the official terminology of the anatomical sciences; nonofficial technical commonly used terms which lead to terminology or translation misunderstanding often being a source of confusion. RESULTS: A table with a sample of the 508 most used anatomical cardiologic terms in English language peer-reviewed journals of cardiology and (pediatric and adult thoracic surgery is shown.

    PurposeImplementation research provides a structure for evaluating the clinical integration of genomic medicine interventions. This paper describes the Implementing Genomics in Practice (IGNITE) Network's efforts to promote (i) a broader understanding of genomic medicine implementation research and (ii) the sharing of knowledge generated in the network.MethodsTo facilitate this goal, the IGNITE Network Common Measures Working Group (CMG) members adopted the Consolidated Framework for Implementation Research (CFIR) to guide its approach to identifying constructs and measures relevant to evaluating genomic medicine as a whole, standardizing data collection across projects, and combining data in a centralized resource for cross-network analyses.ResultsCMG identified 10 high-priority CFIR constructs as important for genomic medicine. Of those, eight did not have standardized measurement instruments. Therefore, we developed four survey tools to address this gap. In addition, we identified seven high-priority constructs related to patients, families, and communities that did not map to CFIR constructs. Both sets of constructs were combined to create a draft genomic medicine implementation model.ConclusionWe developed processes to identify constructs deemed valuable for genomic medicine implementation and codified them in a model. These resources are freely available to facilitate knowledge generation and sharing across the field.

    There have been epidemiological studies of adverse events (AEs) among general patients but those of patients cared by cardiologist are not well scrutinized. We investigated the occurrence of AEs and medical errors (MEs) among adult patients with cardiology in Japan. We conducted a cross-sectional study of adult outpatients at a Japanese teaching hospital from February through November 2006. We measured AE and ME incidents from patient report, which were verified by medical records, laboratory data, incident reports, and prescription queries. Two independent physicians reviewed the incidents to determine whether they were AEs or MEs and to assess severity and symptoms. We identified 144 AEs and 30 MEs (16.3 and 3.9 per 100 patients, respectively). Of the 144 AEs, 99 were solely adverse drug events (ADEs), 20 were solely non-ADEs, and the remaining 25 were both causes. The most frequent symptoms of ADEs were skin and allergic reactions due to medication. The most frequent symptoms of non-ADEs were bleeding due to therapeutic interventions. Among AEs, 12% was life threatening. Life-threatening AEs were 25% of non-ADEs and 5% of ADEs (P = 0.0003). Among the 30 MEs, 21MEs (70%) were associated with drugs. Adverse events were common among cardiology patients. Adverse drug events were the most frequent AEs, and non-ADEs were more critical than ADEs. Such data should be recognized among practicing physicians to improve the patients' outcomes.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

    Although cancer screening reduces morbidity and mortality, millions of people worldwide remain unscreened. Social media provide a unique platform to understand public sentiment toward tools that are commonly used for cancer screening. The objective of our study was to examine public sentiment toward colonoscopy, mammography, and Pap smear and how this sentiment spreads by analyzing discourse on Twitter. In this observational study, we classified 32,847 tweets (online postings on Twitter) related to colonoscopy, mammography, or Pap smears using a naive Bayes algorithm as containing positive, negative, or neutral sentiment. Additionally, we characterized the spread of sentiment on Twitter using an established model to study contagion. Colonoscopy-related tweets were more likely to express negative than positive sentiment (negative to positive ratio 1.65, 95% CI 1.51-1.80, Psocial media data provides a unique, quantitative framework to better understand the public's perception of medical interventions that are commonly used for cancer screening. Given the growing use of social media, public health interventions to improve cancer screening should use the health perceptions of the population as expressed in social network postings about tests that are frequently used for cancer screening, as well as other people they may influence with such postings. ©Omar Metwally, Seth Blumberg, Uri Ladabaum, Sidhartha R.

    Full text: Nuclear Medicine is a medical speciality which employs tomography procedures for the diagnosis, treatment and prevention of diseases. One of the most commonly used apparatus is the Single Photon Emission Computed Tomography (SPECT). To perform exams, a very small amount of a radiopharmaceutical must be given to the patient. Then, a gamma camera is placed in convenient positions to perform the photon counting, which is used to reconstruct a full 3 dimensional distribution of the radionuclide inside the body or organ. This reconstruction provides a 3-dimensional image in spatial coordinates, of the body or organ under study, allowing the physician to give the diagnostic. Image reconstruction is usually worked in the frequency domain, due to a great simplification introduced by the Fourier decomposition of image spectra. After the reconstruction, an inverse Fourier transform must be applied to trace back the image into spatial coordinates. To optimize this reconstruction procedure, digital filters are used to remove undesirable components of frequency, which can 'shadow' relevant physical signatures of diseases. Unfortunately, the efficiency of the applied filter is strongly dependent on its own mathematical parameters. In this work we demonstrate how filters interfere on image quality in cardiology examinations with SPECT, concerning perfusion and myocardial viability and the importance of the medical physicist in the choice of the right filters avoiding some serious problems that could occur in the inadequate processing of an image damaging the medical diagnosis.

    During the last years, since short physical mean life radionuclides have started to be used, radionuclide scanning has been experienced with remarkable culmination. There are detector devices, which jointly with computation equipments, allow to obtain multiple images per second as properly rapid gammagraphic series, in order to obtain whole hemodynamic data or to generate functional images no representing an anatomical structure but reporting about cardiac dynamics at regional level. In these techniques, employed in Nuclear Cardiology, the following radionuclides and radiopharmaceuticals are used: radiolabeled albumin 99m Tc red blood cells, 113m In-transferrin, very short physical mean life radionuclides, such as 195m Au, 178 Ta, 191 Ir. In addition, 113 Xe for coronary flow measurements; radiolabeled microspheres and macroparticles for angiogammagraphy; 129 Cs, 43 K, 81 Rb, 82 Rb and 201 Ti, the most largerly used, for myocardial gammagraphy. It is pointed out that fatty acids are the newest, basically if are radioiodate, and some 99m Tc labeled long chain hydrocarbons. It is expressed that 99m Tc-Sn-pyrophosphate has been used for myocardial infarction. Working on the development of new radiopharmaceuticals, basically fatty acids and 99m Tc chelating agents, for the improvement of these techniques is carried out. (author)

    In the field of nuclear cardiology, 99mTc labeled myocardial perfusion agents such as MIBI, Tetrofosmin and Teboroxime, 111In-antimyosin for imaging of myocardial necrosis, 123I-betamethyl-iodophenylpentadecanoic acid (BMIPP) for imaging of myocardial fatty acid metabolism and 123I-metaiodobenzylguanidine (MIBG) for imaging of myocardial adrenergic function are introduced recently in Japan. Improved image quality and simultaneous evaluation of myocardial perfusion, function and wall motion can be obtained with use of 99mTc labeled myocardial perfusion agents. 111In-antimyosin enables specific imaging of myocardial necrosis which leads to the use for wide variety of heart diseases. Discrepancy of the myocardial perfusion and metabolism in case of stunned myocardium or cardiomyopathy can be evaluated by 123I-BMIPP in conjunction with perfusion agent. Recently wide variety of diseases which may have cardiac adrenergic abnormality are targeted for 123I-MIBG imaging. These new radiopharmaceuticals are expected to be powerful tool for evaluation of the pathophysiology including severity and prognosis and evaluation of the etiology of the various heart diseases.

    Noncommunicable diseases (NCDs) have become the primary health concern for most countries around the world. Currently, more than 36 million people worldwide die from NCDs each year, accounting for 63% of annual global deaths; most are preventable. The global financial burden of NCDs is staggering, with an estimated 2010 global cost of $6.3 trillion (US dollars) that is projected to increase to $13 trillion by 2030. A number of NCDs share one or more common predisposing risk factors, all related to lifestyle to some degree: (1) cigarette smoking, (2) hypertension, (3) hyperglycemia, (4) dyslipidemia, (5) obesity, (6) physical inactivity, and (7) poor nutrition. In large part, prevention, control, or even reversal of the aforementioned modifiable risk factors are realized through leading a healthy lifestyle (HL). The challenge is how to initiate the global change, not toward increasing documentation of the scope of the problem but toward true action-creating, implementing, and sustaining HL initiatives that will result in positive, measurable changes in the previously defined poor health metrics. To achieve this task, a paradigm shift in how we approach NCD prevention and treatment is required. The goal of this American Heart Association/European Society of Cardiology/European Association for Cardiovascular Prevention and Rehabilitation/American College of Preventive Medicine policy statement is to define key stakeholders and highlight their connectivity with respect to HL initiatives. This policy encourages integrated action by all stakeholders to create the needed paradigm shift and achieve broad adoption of HL behaviors on a global scale.

  3. Nuclear Cardiology. Guidance and Recommendations for Implementation in Developing Countries

    International Nuclear Information System (INIS)

    2012-01-01

    Nuclear cardiology represents one of the most widely used non-invasive techniques for the assessment of coronary artery disease and other cardiovascular conditions. It has been proven as a cost effective tool for the management of cardiac patients and usually has a decisive role in diagnosis, prognosis and risk stratification, as well as in evaluation of therapy. Clinical scenarios in which nuclear cardiology can be helpful are continuously expanding, with the identification of special subgroups of patients as potential beneficiaries of these methods and the emergence of technological developments in instrumentation and software that tend to enhance the cost-benefit ratio and the reliability of results. Many developing countries have introduced nuclear cardiology, with increasing use of this technique in view of the epidemic of cardiovascular disease that is taking place in most low to middle income countries. Longer life expectancies, changes in lifestyle, diabetes, overweight and obesity are thought to be some of the factors underlying the rapidly growing incidence of this life threatening condition. Today, cardiovascular diseases are the most common cause of death in adults in most, if not all, countries of the world, although specific diseases show different relative weights according to local socioeconomic conditions. Thus, proper utilization of available resources such as nuclear cardiology and other imaging methods is essential to effectively combat these diseases. The practice of nuclear cardiology, however, is not homogeneous worldwide, owing to differences in technological capabilities, availability of consumables, education and training of human resources, and access to evidence based medicine, among other factors. Evidence based medicine is the judicious use of current best evidence in making decisions about the care of individual patients. The practice of evidence based medicine means integrating individual clinical expertise with the best available

    The role of nuclear medicine in developing countries must be oriented to the local needs for clinical practice, the health care of large populations and the demands for research with sometimes extremely limited resources. To help define the locally differing needs, it is stressed that nuclear medicine provides the unique opportunity to observe the body at the molecular level of organization and thus makes the body biochemically transparent. Depending on the particular diagnostic demands, complex imaging with gamma scintigraphy or emission tomography may be the only method to choose in some instances, but for others it may be an unnecessary luxury. Nuclear cardiology, with the purpose of non-invasively assessing cardiac function, myocardial perfusion and myocardial metabolism, is a particular challenge in both respects for developing countries. Given such requirements, single-probe devices with multipurpose application are less expensive than gamma cameras and promise advanced diagnostic uses. In one examination, left ventricular function, global cardio-pulmonary circulation and the general circulatory adaptation to exercise can be investigated by non-gated simultaneous blood pool measurements over four lung regions, the heart and the liver. In addition, such devices have the advantages of compactness, robustness and electronic stability. Despite enormous difficulties regarding funding, infrastructure, equipment and maintenance, developing countries should be encouraged to participate in the evolution of nuclear medicine by responding and adapting to defined needs and perhaps by maintaining at least one national centre of excellence with capacities for research and training. Funds are best secured by providing an indispensable service in co-operation with the various clinical disciplines. (author)

    Abstract Antiplatelet therapy is the cornerstone of the pharmacologic management of patients with acute coronary syndrome (ACS). Over the last years, several studies have evaluated old and new oral or intravenous antiplatelet agents in ACS patients. In particular, research was focused on assessing superiority of two novel platelet ADP P2Y12 receptor antagonists (i.e., prasugrel and ticagrelor) over clopidogrel. Several large randomized controlled trials have been undertaken in this setting and a wide variety of prespecified and post-hoc analyses are available that evaluated the potential benefits of novel antiplatelet therapies in different subsets of patients with ACS. The aim of this document is to review recent data on the use of current antiplatelet agents for in-hospital treatment of ACS patients. In addition, in order to overcome increasing clinical challenges and implement effective therapeutic interventions, this document identifies all potential specific care pathway for ACS patients and accordingly proposes individualized therapeutic options.

    The goal of this review is to explore the clinical significance of music listening on neuroplasticity and dopaminergic activation by understanding the role of music therapy in addictive behavior treatment. fMRI data has shown that music listening intensely modifies mesolimbic structural changes responsible for reward processing (e.g., nucleus accumbens [NAc]) and may control the emotional stimuli's effect on autonomic and physiological responses (e.g., hypothalamus). Music listening has been proven to induce the endorphinergic response blocked by naloxone, a common opioid antagonist. NAc opioid transmission is linked to the ventral tegmental area (VTA) dopamine release. There are remarkable commonalities between listening to music and the effect of drugs on mesolimbic dopaminergic activation. It has been found that musical training before the age of 7 results in changes in white-matter connectivity, protecting carriers with low dopaminergic function (DRD2A1 allele, etc.) from poor decision-making, reward dependence, and impulsivity. In this article, we briefly review a few studies on the neurochemical effects of music and propose that these findings are relevant to the positive clinical findings observed in the literature. We hypothesize that music intervention enhances brain white matter plasticity through dopaminergic recruitment and that more research is needed to explore the efficacy of these therapies.

    Recent publications have expressed the view that there is a shortage of cardiologists and it is growing worse. Both an increasing demand and a diminishing supply of cardiologists have been projected. An increase in the number of international medical graduates (IMGs) who enter cardiology practice has been proposed as a remedy for a projected shortage. The IMGs have to overcome challenges including clinical practice, language proficiency, and cultural differences before they are incorporated into the fabric of U.S. cardiology. With hard work, perseverance, excellence,compassionate care and support and mentoring, many have contributed to scientific and clinical cardiology in the U.S. Whether in the absence of a present crisis the projected shortage of cardiologists necessitates change in U.S. immigration policy is an open question.

    Specialized cardiology services have contributed to reduced mortality in acute coronary syndromes (ACS).  We sought to evaluate the outcomes of ACS patients admitted to non-cardiology services in Southern Alberta. Retrospective chart review performed on all troponin-positive patients in the Calgary Health Region identified those diagnosed with ACS by their attending team. Patients admitted to non-cardiology and cardiology services were compared, using linked data from the Alberta Provincial Project for Outcomes Assessment in Coronary Heart Disease (APPROACH) registry and the Strategic Clinical Network for Cardiovascular Health and Stroke. From January 1, 2007 to December 31, 2008, 2105 ACS patients were identified, with 1636 (77.7%) admitted to cardiology and 469 (22.3%) to non-cardiology services. Patients admitted to non-cardiology services were older, had more comorbidities, and rarely received cardiology consultation (5.1%). Cardiac catheterization was underutilized (5.1% vs 86.4% in cardiology patients (p cardiology vs. cardiology services (49.1% vs. 11.0% respectively at 4-years, p cardiology services. These patients had worse outcomes, despite adjustment for baseline risk factor differences. Although many patients were appropriately admitted to non-cardiology services, the low use of investigations and secondary prevention medications may contribute to poorer patient outcome. Further research is required to identify process of care strategies to improve outcomes and lessen the burden of illness for patients and the health care system.

    Educational treatment to support social development of children with autism spectrum disorder (ASD) is an important topic in developmental psychiatry. However, it remains difficult to objectively quantify the socio-emotional development of ASD children. To address this problem, we developed a novel analytical method that assesses subjects' complex behaviors using multivariate analysis, 'Behavior Output analysis for Quantitative Emotional State Translation' (BOUQUET). Here, we examine the potential for psycho-cognitive ASD therapy based on comparative evaluations of clinical (human) and experimental (animal) models. Our observations of ASD children (vs. their normally developing siblings) and the domestic chick in socio-sensory deprivation models show the importance of unimodal sensory stimulation, particularly important for tactile- and auditory-biased socialization. Identifying psycho-cognitive elements in early neural development, human newborn infants in neonatal intensive care unit as well as a New World monkey, the common marmoset, also prompted us to focus on the development of voluntary movement against gravity. In summary, striking behavioral similarities between children with ASD and domestic chicks' socio-sensory deprivation models support the role of multimodal sensory-motor integration as a prerequisite step for normal development of socio-emotional and psycho-cognitive functions. Data obtained in the common marmoset model also suggest that switching from primitive anti-gravity reflexes to complex voluntary movement may be a critical milestone for psycho-cognitive development. Combining clinical findings with these animal models, and using multivariate integrative analyses may facilitate the development of effective interventions to improve social functions in infants and in children with neurodevelopmental disorders.

    Hidden traps in decision making have been long recognised in the behavioural economics community. Yet we spend very limited, if any time, analysing our decision-making processes in medicine and paediatric cardiology. Systems 1 and 2 thought processes differentiate between rapid emotional thoughts and slow deliberate rational thoughts. For fairly clear cut medical decisions, in-depth analysis may not be needed, but in our field of paediatric cardiology it is not uncommon for challenging cases and occasionally 'simple' cases to generate significant debate and uncertainty as to the best decision. Although morbidity and mortality meetings frequently highlight poor outcomes for our patients, they often neglect to analyse the process of thought which underlined those decisions taken. This article attempts to review commonly acknowledged traps in decision making in the behavioural economics world to ascertain whether these heuristics translate to decision making in the paediatric cardiology environment. We also discuss potential individual and collective solutions to pitfalls in decision making.

    Gastroenterology and cardiology services are common and costly among Medicare beneficiaries. Episode-based payment, which aims to create incentives for high-quality, low-cost care, has been identified as a promising alternative payment model. This article describes research related to the design of episode-based payment models for ambulatory gastroenterology and cardiology services for possible testing by the Center for Medicare and Medicaid Innovation at the Centers for Medicare and Medicaid Services (CMS). The authors analyzed Medicare claims data to describe the frequency and characteristics of gastroenterology and cardiology index procedures, the practices that delivered index procedures, and the patients that received index procedures. The results of these analyses can help inform CMS decisions about the definition of episodes in an episode-based payment model; payment adjustments for service setting, multiple procedures, or other factors; and eligibility for the payment model.

    Nuclear cardiology has historically played an important role in detection of cardiovascular disease as well as risk statification. With the growth of molecular biology have come new therapeutic interventions and the requirement for new diagnostic imaging approaches. Noninvasive targeted radiotracer based as well as transporter gene imaging strategies are evolving to meet these new needs, but require the development of an interdisciplinary approach which focuses on molecular processes, as well as the pathogenesis and progression of disease. This progress has been made possible with the availability of transgenic animal models along with many technological advances. Future adaptations of the developing experimental procedures and instrumentations will allow for the smooth translation and application to clinical practice. This review is intended as a brief overview on the subject molecular imaging. Basic concepts and historical perspective of molecular imaging will be reviewed first, followed by description of current technology, and concluding with current applications in cardiology. The emphasis will be on the use of both single photon emission computed tomography (SPECT) and positron emission tomography (PET) radiotracers, although other imaging modalities will be also briefly discussed. The specific approaches presented here will include receptor-based and reporter gene imaging of natural and therapeutical angiogenesis

    Aim: few nuclear cardiology surveys, were published in the literature, mostly from developed countries. the aim of this study is to perform a nuclear cardiology survey in iran. This may lead to better decision making and programming. Methods and materials: a questionnaire was sent by mail or e- mail to all nuclear medicine centers in iran asking for details of nuclear cardiology practice in year 2002. Also ownership of the center were studied using telephone interviews. Results: from 79 nuclear medicine centers in Iran, 55 centers (69.6%) filled the questionnaire including 28 centers in Tehran and 27 centers in other cities. Among them, 27 centers were private clinics. There was 69 gamma cameras in these centers, 62.3 % with SPECT capabilities. it is estimated that we may have 100 gamma cameras in Iran. About 85.5 % of centers perform cardiac studies routinely. Tc-99m-MIBI is used in more than 85.7% of the studies and some centers do not use Tl-201. Pharmacological stress with infusion of Dipyridamole is used in 56.7% of the studies and treadmill is the main type of physical exercise (40.2%). SPECT technique was used in 93% of studies including 2.5% of gated SPECT. About 64.3% of centers used two day protocol for imaging.Our study showed that about 65594 cardiac studies were done in Iran each year with myocardial perfusion scan accounting for about 99.2% of the studies. Considering population of the country(about 65 millions) nuclear cardiology activity will be about 1.01 study/1000/year. For viability assessment, Tl-201 with rest redistribution technique is used in 10.7 % of cases while re-injection is used in 29.8% of cases and TNG augmented Tc-99m-MIBI injection at rest in 59.5%. Discussion: Activity of nuclear cardiology is about 15 studies/1000 population/year is USA and 2.2 studies/1000/year in Europe. Although it is not uniformly practiced in different countries of Europe, however the numbers indicate that nuclear cardiology is under utilized in Iran ( less

    Health services are systems whose mission is to improve the health status of both individuals and society in general. In recent decades, these systems have faced challenges such as their increasing complexity, limited resources, rapid innovation and diffusion of medical technologies, pressures on demand from society and professionals, and the lack of knowledge of the effects of these factors on costs and society's health. In addition, health care expenditures have grown twice as fast as wealth in industrialized countries during the last 25 years. These problems have prompted cost containment as a key issue in health policy and, at the same time, have promoted the development of socioeconomic evaluation as a scientific activity in the frame of health services research. Socioeconomic evaluation tries to determine if the sacrifice made by society, which devotes part of its limited resources to health care, maximizes the outcomes for population. This article describes basic concepts and methods of economic appraisal in health services which are illustrated with examples of clinical practice in cardiology. Common methods of evaluation are described; the relation between the clinical outcome of a procedure and its associated costs is emphasized in explaining the types of efficiency analysis (cost-efficacy, cost-effectiveness, cost-utility, and cost-benefit); and finally a guide for socioeconomic evaluation is provided.

    Given high rates of heart failure (HF) hospitalizations and widespread adoption of the hospitalist model, patients with HF are often cared for on General Medicine (GM) services. Differences in discharge processes and 30-day readmission rates between patients on GM and those on Cardiology during the contemporary hospitalist era are unknown. The present study compared discharge processes and 30-day readmission rates of patients with HF admitted on GM services and those on Cardiology services. We retrospectively studied 926 patients discharged home after HF hospitalization. The primary outcome was 30-day all-cause readmission after discharge from index hospitalization. Although 60% of patients with HF were admitted to Cardiology services, 40% were admitted to GM services. Prevalence of cardiovascular and noncardiovascular co-morbidities were similar between patients admitted to GM services and Cardiology services. Discharge summaries for patients on GM services were less likely to have reassessments of ejection fraction, new study results, weights, discharge vital signs, discharge physical examinations, and scheduled follow-up cardiologist appointments. In a multivariable regression analysis, patients on GM services were more likely to experience 30-day readmissions compared with those on Cardiology services (odds ratio 1.43 95% confidence interval [1.05 to 1.96], p = 0.02). In conclusion, outcomes are better among those admitted to Cardiology services, signaling the need for studies and interventions focusing on noncardiology hospital providers that care for patients with HF.

    perform new revascularization procedures and hospital readmissions. The overall success of the drug-eluting stents has proven to be reliable and consistent in overcoming restenosis and has some beneficial impact for all clinical and angiographic conditions. This paper discusses the adoption and criteria for the use of drug-eluting stents in other countries as well as the recommendations established by the Brazilian Society of Interventional Cardiology for their reimbursement by SUS. The incorporation of new healthcare technology involves two distinct stages. During the first stage, the product is registered with the National Health Surveillance Agency (ANVISA. During this stage the interested company submits to the regulatory agency, results from clinical studies that demonstrate the efficacy and safety of the new device or pharmaceutical product. Frequently, in addition to clinical studies, approval records for clinical use from the regulatory agencies of other countries, mainly the United States of America and the European Community are also submitted. The successful completion of this stage means that the medication or device may be prescribed or used by the physicians in Brazil. The second stage in the incorporation of new healthcare technology involves the reimbursement or financing of the treatment that was approved in the previous stage based on its efficacy and safety. This stage can be more complex than the first one since the new technology, whether a substitution for established treatment methods or the introduction of a new treatment concept, are usually more expensive. The incorporation of new technology requires a cost-effectiveness analysis so that fund administrators can make decisions based on the universal scenario of limited resources to finance healthcare with treatments that are more and more burdensome. The difficulties of funding management are aggravated by medical and social ethical implications that arise when a treatment is approved based on its

    2016-05-01

    Smartphone-based technologies along with broadband connectivity are changing the way modern cardiology is practiced. The ever broadening connectivity and increasing capabilities of smartphone-based technologies can better monitor, diagnose, and prevent cardiovascular diseases. Researchers can leverage the ubiquitous use of smartphone-based technologies and their constant stream of biometric data to establish large community-based clinical research studies. Patient engagement is enhanced with constant and on-demand access to physicians, daily self-monitoring, and expanding social networks. On the other hand, the exponential growth of smartphone-based technologies invariably disrupts the traditional healthcare model and leaves a vacuum in the infrastructure, medico-legal apparatus, and reimbursement systems that need to be addressed. In this review, we present a comprehensive discussion of the various applications utilizing smartphone-based technologies in cardiology. Copyright © 2016 Elsevier Inc. All rights reserved.

    2017-01-01

    Cardiovascular disease (CVD) accounts for more deaths globally than any other single disease. There are on average 1.5 million episodes of myocardial infarction (heart attack) each year in the United States alone with roughly one third resulting in death. There is therefore a major need for developing new and effective strategies to promote cardiac repair. Intramyocardial transplantation of mesenchymal stem cells (MSCs) has emerged as a leading contender in the pursuit of clinical intervention and therapy. MSCs are potent mediators of cardiac repair and are therefore an attractive tool in the development of pre-clinical and clinical trials. MSCs are capable of secreting a large array of soluble factors, which have had demonstrated effects on pathogenic cardiac remolding, fibrosis, immune activation and cardiac stem cell proliferation within the damaged heart. MSCs are also capable of differentiation into cardiomyocytes, endothelial cells and vascular smooth muscle cells, although the relative contribution of trilineage differentiation and paracrine effectors on cardiac repair remains the subject of active investigation.

    In the present article, we review publications from the previous year in the following 3 areas: clinical cardiology, geriatric cardiology, and heart failure and transplantation. Among the new developments in clinical cardiology are several contributions from Spanish groups on tricuspid and aortic regurgitation, developments in atrial fibrillation, syncope, and the clinical characteristics of heart disease, as well as various studies on familial heart disease and chronic ischemic heart disease. In geriatric cardiology, the most relevant studies published in 2014 involve heart failure, degenerative aortic stenosis, and data on atrial fibrillation in the geriatric population. In heart failure and transplantation, the most noteworthy developments concern the importance of multidisciplinary units and patients with preserved systolic function. Other notable publications were those related to iron deficiency, new drugs, and new devices and biomarkers. Finally, we review studies on acute heart failure and transplantation, such as inotropic drugs and ventricular assist devices. Copyright © 2014 Sociedad Española de Cardiología.

    Congenital heart disease encompasses abnormalities in cardiac development which generally have in common either valve stenoses or connections between chambers or great vessels. Usually, abnormalities of intracardiac anatomy, and often, abnormalities of great vessel anatomy, can be unraveled by two-dimensional echocardiography. However, echocardiography offers little information regarding flow characteristics in the various congenital lesions. Addition of the Doppler principle, particularly when combined with the two-dimensional examination, can characterize the source of a flow disturbance, quantify gradients across a site of obstruction, and quantify flow volume across sites where flow is nonturbulent. These features make Doppler echocardiography unique for noninvasive accurate evaluation of children and adults with various forms of congenital heart disease. In this report, the authors discuss some of the present uses of Doppler echocardiography in congenital heart disease. Application of this technique requires greater understanding of certain physics principles than does routine echocardiography

    Establishing paediatric cardiology service in a country with limited resources like Sudan is a challenging task. A paediatric cardiac team was formed then the services in different disciplines were gradually established. Echocardiography (echo) clinics were founded in tertiary and peripheral hospitals. Cardiac catheterization (cath) was established at the Sudan Heart Centre (SHC) in 2004 and over 400 procedures had been performed including interventional catheterization like pulmonary valve dilatation, patent ductus arteriosus and atrial septal defect device closure. Congenital heart surgery started in 2001, currently 200 cases are done each year including closed procedures as well as open heart procedures for patients weighing more than 8 kg. Cardiology-cardiac surgery as well as adult congenital heart disease meetings were held and contributed positively to the services. The cardiology-cardiac surgery scientific club meeting was founded as a forum for academic discussions. A fellowship program was established in 2004 and included seven candidates trained in paediatric cardiology and intensive care. Two training courses had been established: congenital heart disease echo and paediatric electrocardiogram interpretation. Links with regional and international cardiac centres had important roles in consolidating our program. Significant obstacles face our service due to the small number of trained personnel, high cost of procedures, the lack of regular supplies and lack of cardiac intensive care facilities for young infants. Bridging the huge gap needs extensive official as well as non-governmental efforts, training more staff, supporting families and collaboration with regional and international centres.

Novel interventions are required that target underlying factors of multiple disorders. To evaluate the efficacy of a transdiagnostic trait-focused web-based intervention aimed at reducing symptoms of common mental disorders in university students. Students were recruited online (n=1047, age: M=21.8, SD=4.2) and categorised into being at high or low risk for mental disorders based on their personality traits. Participants were allocated to a cognitive-behavioural trait-focused (n=519) or a control intervention (n=528) using computerised simple randomisation. Both interventions were fully automated and delivered online (trial registration: ISRCTN14342225). Participants were blinded and outcomes were self-assessed at baseline, at 6 weeks and at 12 weeks after registration. Primary outcomes were current depression and anxiety, assessed on the Patient Health Questionnaire (PHQ9) and Generalised Anxiety Disorder Scale (GAD7). Secondary outcome measures focused on alcohol use, disordered eating, and other outcomes. Students at high risk were successfully identified using personality indicators and reported poorer mental health. A total of 520 students completed the 6-week follow-up and 401 students completed the 12-week follow-up. Attrition was high across intervention groups, but comparable to other web-based interventions. Mixed effects analyses revealed that at 12-week follow up the trait-focused intervention reduced depression scores by 3.58 (pmental disorders with a low-intensity intervention.

    The use of complementary and alternative medicine (CAM) is increasing in Western countries, including in the area of dermatology. However, Western healthcare providers have not integrated CAM into regular practice owing to a lack of reliable data supporting its use. To encourage high-quality research related to the use of CAM and specifically herbal interventions, the CONsolidated Standards Of Reporting Trials (CONSORT) extension criteria on reporting herbal interventions (hCONSORT) were published in 2006. To evaluate the adherence of randomized controlled trials (RCTs) investigating herbal interventions for acne, atopic dermatitis (AD) and psoriasis to the hCONSORT criteria. A comprehensive search of the PubMed, Embase and Cochrane Library databases was conducted. RCTs published between 2009 and 2014 assessing therapeutic outcomes of plant-based interventions for acne, AD or psoriasis were included. Investigators determined the number of unique hCONSORT criteria satisfied per report. anova was used to examine differences in scores by disease entity. The vast majority of reviewed studies reported reports based on language and lack of assessment of overall adherence to CONSORT criteria. Our data indicate lack of adherence to hCONSORT extension criteria. Adherence to hCONSORT guidelines should be encouraged in order to provide high-quality reporting of research on herbal interventions in dermatology. Doing so may ease the integration of CAM into conventional medical practice and provide actionable data to providers. © 2017 British Association of Dermatologists.

    Pediatric interventionalists and surgeons treating congenital heart defects at the KinderSpital children's hospital in Zurich, Switzerland, use a ''hybrid'' approach to minimize the incidence and extent of open-heart surgery. The hybrid approach combines catheterization and surgical techniques in a single procedure, performed in the same lab. The combined cardiac cath lab/surgery suite is equipped with a Philips Integris Allura BH5000 9''/9'' biplane system, designed to meet all the requirements for pediatric applications, including the need to keep the quantity of contrast agent and the radiation dose to the minimum. Wherever possible, diagnostic X-ray examinations are supplemented by MR and Ultrasound. (orig.)

    Rates of common mental health problems are much higher in prison populations, but access to primary care mental health support falls short of community equivalence. Discontinuity of care on release is the norm and is further complicated by substance use and a range of social problems, e.g. homelessness. To address these problems, we worked with criminal justice, third sector social inclusion services, health services and people with lived experiences (peer researchers), to develop a complex collaborative care intervention aimed at supporting men with common mental health problems near to and following release from prison. This paper describes an external pilot trial to test the feasibility of a full randomised controlled trial. Eligible individuals with 4 to 16 weeks left to serve were screened to assess for common mental health problems. Participants were then randomised at a ratio of 2:1 allocation to ENGAGER plus standard care (intervention) or standard care alone (treatment as usual). Participants were followed up at 1 and 3 months' post release. Success criteria for this pilot trial were to meet the recruitment target sample size of 60 participants, to follow up at least 50% of participants at 3 months' post release from prison, and to deliver the ENGAGER intervention. Estimates of recruitment and retention rates and 95% confidence intervals (CIs) are reported. Descriptive analyses included summaries (percentages or means) for participant demographics, and baseline characteristics are reported. Recruitment target was met with 60 participants randomised in 9 months. The average retention rates were 73% at 1 month [95% CI 61 to 83] and 47% at 3 months follow-up [95% CI 35 to 59]. Ninety percent of participants allocated to the intervention successfully engaged with a practitioner before release and 70% engaged following release. This pilot confirms the feasibility of conducting a randomised trial for prison leavers with common mental health problems. Based

    Enigmas often lead to hypotheses and speculations. For this reason, especially for the sake of the reader's motivation, we opted for the plain discussion of some cardiology enigmas. The present text was aimed to discuss speculatively some cardiology enigmas. Text was freely designed in the context of coronary artery and heart valve diseases. The results were presented as the combination enigma/hypothesis. 1) The absence of arteriosclerosis in intramyocardial coronary arteries/ endothelium-myocardial interaction (crosstalk); 2) The unique and always confirmed superior evolution of the internal thoracic artery as coronary graft/ higher NO basal release 3) The prophylactic left internal thoracic artery graft in mildlystenosed coronary lesions/need of more accurate functional imaging techniques; 4) The high incidence of perioperative atrial fibrillation in patients with coronary artery disease/atrial ischemia associated to left circumflex coronary lesions; 5) The handling of disease-free saphenous vein grafts at the time of reoperation/biological serendipity with graft vein segments; 6) The possible aortic stenosis protection against coronary artery disease/ endothelium-myocardium interaction (crosstalk) improving NO release. The discussed topics associated with their respective speculative hypothesis remain as enigmas, but would become motivations for investigations.

  12. The use of MR in cardiological diagnostics

    Smith, Hans-Joergen

    2004-01-01

    Image diagnostics is playing an important role in cardiology, and magnetic resonance tomography (MR) is one of many methods used in examinations of the heart. Based on studies of the literature and his own experience the author surveys the potential of MR in today's and tomorrow's diagnostics of heart diseases. Among the image diagnostic methods MR is the one that can give the most extensive information about the heart's anatomy and function. In a non-invasive way and without the use of ionizing radiation, MR can represent the anatomy in selectable planes, visualize and quantify the heart's pumping function and functioning of the cardiac valves, and give detailed information about the regional contractility, blood flow and viability of myocard. MR is capable of giving important and to some extent unique contributions to heart diseases, both congenital and contracted heart disease. Because of failing availability and competence MR is still little used in cardiological diagnostics, but the method undoubtedly has the potential to play a very important role in the future

    The aim of this study was to assess cardiological manifestations of carbon monoxide (CO) poisoning. Background/introduction: Carbon monoxide intoxication is one of the most important toxicological causes of morbidity and mortality worldwide. Early clinical manifestation of CO poisoning is cardiotoxicity. We enrolled 75 patients (34 males and 41 females, mean age 37.6 ± 17.7 y/o) hospitalized due to CO poisoning. Laboratory tests including troponin I, blood pressure measurements, HR and electrocardiograms (ECG) were collected. Pach's scale scoring and grading system was used to establish severity of poisoning. Grade of poisoning is positively correlated with troponin I levels and systolic blood pressure. Moreover, troponin levels are significantly correlated with exposition time, lactates and are higher in tachycardiac, hypertensive and positive ECG subpopulations. COHb levels are indicative of exposure but do not correlate with grade of poisoning. The main cause of CO poisoning were bathroom heaters - 83%, only 11% of examined intoxicated population were equipped with CO detectors. Complex cardiological screening covering troponin levels, ECG, blood pressure and heart rate measurements as well as complete blood count with particular attention to platelet parameters should be performed in each case where CO intoxication is suspected. More emphasis on education on CO poisoning is needed.

    Data mining (DM) provides the methodology and technology needed to transform huge amounts of data into useful information for decision making. It is a powerful process employed to extract knowledge and discover new patterns embedded in large data sets. Data mining has been increasingly used in medicine, particularly in cardiology. In fact, DM applications can greatly benefit all those involved in cardiology, such as patients, cardiologists and nurses. The purpose of this paper is to review papers concerning the application of DM techniques in cardiology so as to summarize and analyze evidence regarding: (1) the DM techniques most frequently used in cardiology; (2) the performance of DM models in cardiology; (3) comparisons of the performance of different DM models in cardiology. We performed a systematic literature review of empirical studies on the application of DM techniques in cardiology published in the period between 1 January 2000 and 31 December 2015. A total of 149 articles published between 2000 and 2015 were selected, studied and analyzed according to the following criteria: DM techniques and performance of the approaches developed. The results obtained showed that a significant number of the studies selected used classification and prediction techniques when developing DM models. Neural networks, decision trees and support vector machines were identified as being the techniques most frequently employed when developing DM models in cardiology. Moreover, neural networks and support vector machines achieved the highest accuracy rates and were proved to be more efficient than other techniques. Copyright © 2016 Elsevier Ireland Ltd.

    The paper presents the origins of the Czech Society of Cardiology on the one hand, and the origins of Czech cardiology on the other. The Czech Society of Cardiology is the third oldest in the world (after the American and German Societies). It was founded in 1929 by Prof. Libenský. As early as in 1933, the Society organised the first international congress of cardiologists in Prague, which was attended by 200 doctors, out of which 50 were from abroad. The most participants came from France and Poland. Other participants came from England, Argentina, Belgium, the Netherlands, Italy, Romania, Spain and Switzerland. The worldwide importance of this congress is apparent from the fact that both the World Society of Cardiology and the European Society of Cardiology (EKS) were founded after World War II in the years 1950 and 1952, i.e. almost 20 years after the first international congress of cardiology in Prague. In 1964, the Fourth Congress of European Society of Cardiology was held in Prague with the participation of 1,500 specialists from 31 countries and chaired by Prof. Pavel Lukl, the later president of EKS (1964- 1968). The paper also presents the work of our specialists in WHO and the history of the international journal Cor et Vasa issued by the Avicenum publishing house in Prague in English and Russian in the years 1958- 1992. An important role in the development of our cardiology was played by certain departments and clinics. In 1951, the Institute for Cardiovascular Research (ÚCHOK) was founded in PrahaKrč, thanks to the initiative of MU Dr. František Kriegl, the Deputy Minister of Health. Its first director was Klement Weber, who published, as early as in 1929, a monograph on arrhythmias -  50 years earlier than arrhythmias started to be at the centre of attention of cardiologists. Klement Weber was one of the doctors of President T. G. Masaryk during his serious disease towards the end of his life. Jan Brod was the deputy of Klement Weber in the

    The treatment of children with cardiac disease is one of the most prevalent and costly pediatric inpatient conditions. The design of inpatient medical services for children admitted to and discharged from noncritical cardiology care units, however, is undefined. North American Pediatric Cardiology Programs were surveyed to define noncritical cardiac care unit models in current practice. An online survey that explored institutional and functional domains for noncritical cardiac care unit was crafted. All questions were multi-choice with comment boxes for further explanation. The survey was distributed by email four times over a 5-month period. Most programs (n = 45, 60%) exist in free-standing children's hospitals. Most programs cohort cardiac patients on noncritical cardiac care units that are restricted to cardiac patients in 39 (54%) programs or restricted to cardiac and other subspecialty patients in 23 (32%) programs. The most common frontline providers are categorical pediatric residents (n = 58, 81%) and nurse practitioners (n = 48, 67%). However, nurse practitioners are autonomous providers in only 21 (29%) programs. Only 33% of programs use a postoperative fast-track protocol. When transitioning care to referring physicians, most programs (n = 53, 72%) use facsimile to deliver pertinent patient information. Twenty-two programs (31%) use email to transition care, and eighteen (25%) programs use verbal communication. Most programs exist in free-standing children's hospitals in which the noncritical cardiac care units are in some form restricted to cardiac patients. While nurse practitioners are used on most noncritical cardiac care units, they rarely function as autonomous providers. The majority of programs in this survey do not incorporate any postoperative fast-track protocols in their practice. Given the current era of focused handoffs within hospital systems, relatively few programs utilize verbal handoffs to the referring pediatric

    The American College of Cardiology Adult Congenital and Pediatric Cardiology (ACPC) Section had attempted to create quality metrics (QM) for ambulatory pediatric practice, but limited evidence made the process difficult. The ACPC sought to develop QMs for ambulatory pediatric cardiology practice. Five areas of interest were identified, and QMs were developed in a 2-step review process. In the first step, an expert panel, using the modified RAND-UCLA methodology, rated each QM for feasibility and validity. The second step sought input from ACPC Section members; final approval was by a vote of the ACPC Council. Work groups proposed a total of 44 QMs. Thirty-one metrics passed the RAND process and, after the open comment period, the ACPC council approved 18 metrics. The project resulted in successful development of QMs in ambulatory pediatric cardiology for a range of ambulatory domains. Copyright © 2017 American College of Cardiology Foundation.

  19. Clinical use of nuclear cardiology in the assessment of heart failure

    2011-01-01

    Nuclear cardiology is the most commonly performed non-invasive cardiac imaging test in patients with heart failure, and it plays an important role in their assessment and management. Quantitative gated single positron emission computed tomography is used to assess quantitatively cardiac volume, left ventricular ejection fraction, stroke volume, and cardiac diastolic function. Resting and stress myocardial perfusion imaging can not only identify nonischemic heart failure and ischemic heart failure, but also demonstrate myocardial viability. Diastolic heart failure also termed as heart failure with a preserved left ventricular ejection fraction is readily identified by nuclear cardiology techniques and can accurately be estimated by peak filling rate and time to peak filling rate. With newer techniques such as three-dimensional, quantitative gated single positron emission computed tomography can assess movement of the left ventricle, and wall thickening evaluation aids its assessment. Myocardial perfusion imaging is also commonly used to identify candidates for implantable cardiac defibrillator and cardiac resynchronization therapies. Neurotransmitter imaging using 123 I-metaiodobenzylguanidine offers prognostic information in patients with heart failure. Metabolism and function in the heart are closely related, and energy substrate metabolism is a potential target of medical therapies to improve cardiac function in patients with heart failure. Cardiac metabolic imaging using 123 I-15-(p-iodophenyl) 3-R, S-methylpentadecacoic acid is a commonly used tracer in clinical studies to diagnose metabolic heart failure. Nuclear cardiology tests, including neurotransmitter imaging and metabolic imaging, are now easily preformed with new tracers to improve heart failure diagnosis. Nuclear cardiology techniques contribute significantly to identifying patients with heart failure and to guiding their management decisions. (authors)

    The use of myocardial perfusion imaging has seen a tremendous growth during the last decade and has become the most commonly used non-invasive imaging tool for risk stratification in patients with suspected and known coronary artery disease. Adherence to radiation safety best practices varied significantly between laboratories but the possibility to use the new cameras in nuclear cardiology can reduce dramatically the radiation dose without losing accuracy. Moreover, the physical characteristics of ultrafast technology could be able to open new doors for the evaluation of old parameters, changing the impact of nuclear cardiology in the diagnostic strategies.

    Common mental disorders, such as depression and anxiety, pose a major public health burden in developing countries. Although these disorders are thought to be best managed in primary care settings, there is a dearth of evidence about how this can be achieved in low resource settings. The MANAS project is an attempt to integrate an evidence based package of treatments into routine public and private primary care settings in Goa, India. Before initiating the trial, we carried out extensive preparatory work, over a period of 15 months, to examine the feasibility and acceptability of the planned intervention. This paper describes the systematic development and evaluation of the intervention through this preparatory phase. The preparatory stage, which was implemented in three phases, utilized quantitative and qualitative methods to inform our understanding of the potential problems and possible solutions in implementing the trial and led to critical modifications of the original intervention plan. Investing in systematic formative work prior to conducting expensive trials of the effectiveness of complex interventions is a useful exercise which potentially improves the likelihood of a positive result of such trials.

  2. Application of Contrast Echocardiography in Invasive Cardiology

    Directory of Open Access Journals (Sweden)

    Mustafa Bulut

    2010-12-01

    Full Text Available Contrast echocardiography by rendering better imaging of the borders of cardiac chambers is a useful tool for evaluating cardiac function, mass, myocardial vascularization, microvascular structure (small vessel vasculature and viability. Contrast was first started to be used for patients with suboptimal image quality. It can be used in detecting defects in myocardial blood supply in patients with chest pain and determining the success of interventionalprocedures. It can also be of help in demonstrating myocardial viability after reperfusion treatment in patients who had myocardial infarction. It is expected to be used more widely in invasive cardiology for decision making, guiding and determining the success of the procedures. Advances in imaging techniques , development of contrast materials for evaluation of left system, contrast echocardiography may become a routine clinical practice.

    In recent years Cardiologists have shown an increasing interest on the use of Magnetic Resonance Imaging (MRI) for assessing cardiovascular diseases. The first generation of MRI equipment dedicated to cardiology is now available. The MRI Laboratory of Clinical Physiology Institute in Pisa has joined a multi-centric international project for the development of prototype of this dedicated machine and is currently involved in several subprojects such as the study of myocardial perfusion and the assessment of congenital heart diseases. An interdisciplinary group (cardiologists, software and hardware engineers, biologists, etc.) is full time involved in the development of new analysis algorithms, etc. The new concept of installing a MRI machine within clinical cardiovascular department has started to induce fruitful cooperations either in the research field or in the clinical setting [it

  4. Radioiodinated fatty acids for cardiological diagnosis

    Machulla, H.-J.; Knust, E.J.

    1986-01-01

    The development of fatty acids labelled with iodine-123 is reviewed. The variety of methods for producing 123 I and introducing radioiodine into the molecule is discussed and the important points of the biochemical background are recalled with the aim of finding a broad application for 123 I-labelled fatty acids. The results of the pharmacokinetic studies and biochemical analysis are presented as they prove that both 17- 123 I-heptadecanoic acid (IHA) and 15-(rho- 123 I-phenyl)pentadecanoic acid (IPPA) exhibit analogous behaviour to that of the naturally occurring fatty acids. Clinical applications demonstrated two fields of importance: (i) applications solely for imaging the heart and (ii) assessment of myocardial turnover rates of fatty acids for functional diagnosis. Moreover, very recent studies show that the provision of information about prognosis of myocardial diseases and the applied cardiological therapy appear to be possible. (author)

    2009-01-01

    As some procedures of interventional radiology are complex and long, doses received by patients can be high and cause undesired effects, notably on the skin or in underlying tissues (particularly in the brain as far as interventional neuroradiology is concerned and in lungs in the case of interventional cardiology). The author briefly discusses some deterministic effects in interventional radiology (influence of dose level, delay of appearance of effects, number of accidents). He briefly comments the diagnosis and treatment of severe radiological burns

    2004-01-01

    Objective: To evaluate the criteria for cardiology referrals and to assess the perioperative relevance of the cardiology advice given in patients evaluated for non-cardiac surgery. Materials and Methods: A review of case files of 70 patients, scheduled for non-cardiac surgery, who were referred for cardiology consultations from the Anaesthesia Clinic at AKUH during the study period. The clinical criteria for seeking cardiology advice, the cardiology advice given, its influence on patient management, as well as number of adverse cardiac events in the perioperative period were documented. Results: A history of hypertension, ischemic heart disease, and ECG abnormalities were the major criteria for seeking opinion on cardiac status. Cardiology advice frequently resulted in the ordering of extensive cardiac investigations. Among the patients identified for further tests by the cardiologists, 75% had no evidence of ischemic heart disease or myocardial dysfunction; none of them were monitored invasively intraoperatively or had adverse cardiac events in the perioperative period requiring intensive care or prolonged hospital stay. Conclusion: No definite criteria or pattern for referrals was identified. Most of the referrals did not fall within the AHA guidelines. Cardiology advice given had very little influence on the perioperative management. (author)

    Cardiac disease, both congenital and acquired, contributes significantly to morbidity and mortality in children. This article describes the status of pediatric cardiology at the Children's Heart Center in the American University of Beirut Medical Center. It addresses the available clinical services as well as the research and educational activities that are present at a tertiary center in Lebanon, a developing country with a population of 4 million. Lebanon has witnessed major developments in the field of pediatric cardiology over the past few years. About 650 babies are born with heart disease every year, with more than 425 needing treatment. Nearly all types of interventional catheterization procedures are currently being performed. About 300 open and closed pediatric cardiac surgeries are performed per year in Lebanon. In 2008, the in-hospital surgical mortality rate at our center was 2.6%, reflecting the good level of care in the treatment of children with congenital heart disease (CHD) in Lebanon. Basic research in the field of pediatric cardiology is emerging at our center. Our team has been studying the effect of chronic hypoxemia on the neonatal myocardium in an animal model of chronic hypoxia, as well as the study of molecular basis of CHD. Appropriate identification of cardiac disease, its epidemiology, and outcome is of utmost importance in guiding adequate care. Centralization of facilities is important to improve results and level of care.

    Nutrition is one of the foundations of cardiovascular guidelines for risk reduction and treatment. However, little is known about whether cardiologists, cardiology fellows-in-training, and cardiovascular team members have the nutrition education and knowledge necessary to implement these guidelines. The aim of this study was to describe the educational experiences, attitudes, and practices relating to nutrition among cardiovascular professionals. Surveys completed by cardiologists, fellows-in-training, and cardiovascular team members inquired about their personal dietary habits, history of nutrition education, and attitudes regarding nutrition interventions. A total of 930 surveys were completed. Among cardiologists, 90% reported receiving no or minimal nutrition education during fellowship training, 59% reported no nutrition education during internal medicine training, and 31% reported receiving no nutrition education in medical school. Among cardiologists, 8% described themselves as having "expert" nutrition knowledge. Nevertheless, fully 95% of cardiologists believe that their role includes personally providing patients with at least basic nutrition information. The percentage of respondents who ate ≥5 servings of vegetables and fruits per day was: 20% (cardiologists), 21% (fellows-in-training), and 26% (cardiovascular team members). A large proportion of cardiovascular specialists have received minimal medical education and training in nutrition, and current trainees continue to experience significant education and training gaps.

    Nuclear cardiology is widely used to diagnose coronary artery disease and to guide patient management, but data on current practices, radiation dose-related best practices, and radiation doses are scarce. To address these issues, the IAEA conducted a worldwide study of nuclear cardiology practice. We present the European subanalysis. In March 2013, the IAEA invited laboratories across the world to document all SPECT and PET studies performed in one week. The data included age, gender, weight, radiopharmaceuticals, injected activities, camera type, positioning, hardware and software. Radiation effective dose was calculated for each patient. A quality score was defined for each laboratory as the number followed of eight predefined best practices with a bearing on radiation exposure (range of quality score 0 - 8). The participating European countries were assigned to regions (North, East, South, and West). Comparisons were performed between the four European regions and between Europe and the rest-of-the-world (RoW). Data on 2,381 European patients undergoing nuclear cardiology procedures in 102 laboratories in 27 countries were collected. A cardiac SPECT study was performed in 97.9 % of the patients, and a PET study in 2.1 %. The average effective dose of SPECT was 8.0 ± 3.4 mSv (RoW 11.4 ± 4.3 mSv; P < 0.001) and of PET was 2.6 ± 1.5 mSv (RoW 3.8 ± 2.5 mSv; P < 0.001). The mean effective doses of SPECT and PET differed between European regions (P < 0.001 and P = 0.002, respectively). The mean quality score was 6.2 ± 1.2, which was higher than the RoW score (5.0 ± 1.1; P < 0.001). Adherence to best practices did not differ significantly among the European regions (range 6 to 6.4; P = 0.73). Of the best practices, stress-only imaging and weight-adjusted dosing were the least commonly used. In Europe, the mean effective dose from nuclear cardiology is lower and the average quality score is higher than in the RoW. There is regional variation in effective dose in

  11. Career choices for cardiology: cohort studies of UK medical graduates

    Science.gov (United States)

    2013-01-01

    Background Cardiology is one of the most popular of the hospital medical specialties in the UK. It is also a highly competitive specialty in respect of the availability of higher specialty training posts. Our aims are to describe doctors’ early intentions about seeking careers in cardiology, to report on when decisions about seeking a career in cardiology are made, to compare differences between men and women doctors in the choice of cardiology, and to compare early career choices with later specialty destinations. Methods Questionnaire surveys were sent to all UK medical graduates in selected qualification years from 1974–2009, at 1, 3, 5, 7 and 10 years after graduation. Results One year after graduation, the percentage of doctors specifying cardiology as their first choice of long-term career rose from the mid-1990s from 2.4% (1993 cohort) to 4.2% (2005 cohort) but then fell back to 2.7% (2009 cohort). Men were more likely to give cardiology as their first choice than women (eg 4.1% of men and 1.9% of women in the 2009 cohort). The percentage of doctors who gave cardiology as their first choice of career declined between years one and five after qualification: the fall was more marked for women. 34% of respondents who specified cardiology as their sole first choice of career one year post-graduation were later working in cardiology. 24% of doctors practising as cardiologists several years after qualification had given cardiology as their sole first choice in year one. The doctors’ ‘domestic circumstances’ were a relatively unimportant influence on specialty choice for aspiring cardiologists, while ‘enthusiasm/commitment’, ‘financial prospects’, ‘experiences of the job so far’ and ‘a particular teacher/department’ were important. Conclusions Cardiology grew as a first preference one year after graduation to 2005 but is now falling. It consistently attracts a higher percentage of men than women doctors.

    Nuclear cardiology is no longer a medical discipline residing solely in nuclear medicine. This is the first book to recognize this fact by integrating in-depth information from both the clinical cardiology and nuclear cardiology literature, and acknowledging cardiovascular medicine as the fundamental knowledge base needed for the practice of nuclear cardiology. The book is designed to increase the practitioner's knowledge of cardiovascular medicine, thereby enhancing the quality of interpretations through improved accuracy and clinical relevance.The text is divided into four sections covering all major topics in cardiology and nuclear cardiology: -Basic Sciences and Cardiovascular Diseases; -Conventional Diagnostic Modalities; -Nuclear Cardiology; -Management of Cardiovascular Diseases.

    The future is always hard to forecast but the prospect of nuclear cardiology has never been more unobtainable than these days. Myocardial perfusion single-photon emission computed tomography (MPS) has been one of the major nuclear medicine studies for decades, but the annual number of MPS is stagnant or steadily decreasing in Korea and other countries. The challenge from coronary computed tomography (CCT) and the concern of radiation exposure of MPS were the main reasons for the stalemate of nuclear cardiology. Compared to the rapid technological progress of CCT, enabling greater image resolution in conjunction with lower radiation exposure to the patients, development of new radiopharmaceuticals or scintillation imaging techniques has been at a relatively slow pace. Therefore, the future of nuclear cardiology is really dependent on the application of the genuine nuclear medicine principle to patient's management. The review for current update of nuclear cardiology will ensue in the next issue of Nuclear Medicine and Molecular Imaging.

    Acute ischemic stroke is a catastrophic cardiovascular disease with frequent cardiac causes and cerebral consequences, thus the close cooperation between neurologists and cardiologists is necessary for the optimal patient management. Furthermore, recent randomized trials demonstrated, that catheter-based thrombectomy (CBT) is the most effective treatment for properly selected patients. Interventional cardiology with its widespread non-stop services for acute myocardial infarction can fill the existing gaps in coverage of population needs with neurointerventional services. Thus, a new future medical subspecialization may emerge: neurocardiology or cardioneurology.

    Participating in a scholarly activity is one of the training requirements for cardiology fellows. However, it can be very challenging to complete a research project during such a busy period of clinical training. To help the cardiology fellows in choosing and starting off a research project, a light has been shed on the process of conducting a systematic review, and the importance of this research activity, as well as its limitations. © 2016 Wiley Periodicals, Inc.

    Coronary artery disease is on the rise over the world. Myocardial perfusion SPECT is a well established technique to detect coronary artery disease and to assess left ventricular function. In addition, it has the unique ability to predict the prognosis of the patients. Moreover, the application of ECG-gated images provided the quantitative data and improved the accuracy. This approach has been proved to be cost-effective and suitable for the emerging economies as well as developed countries. However, the utilization of nuclear cardiology procedures vary widely considering the different countries and region of the world. Korea exits 2-3 times less utilization than Japan, and 20 times than the United States. Recently, with the emerging of new technology, namely cardiac CT, cardiac MR and stress echocardiography, the clinical usefulness of nuclear cardiology has been called in question and its role has been redefined. For the proper promotion of nuclear cardiology, special educations should be conducted since the nuclear cardiology has the contact points between nuclear medicine and cardiology. Several innovations are in horizon which will impact the diagnostic accuracy as well as imaging time and cost savings. Development of new tracers, gamma camera technology and hybrid systems will open the new avenue in cardiac imaging. The future of nuclear cardiology based on molecular imaging is very exciting. The newly defined biologic targets involving atherosclerosis and vascular vulnerability will allow the answers for the key clinical questions. Hybrid techniques including SPECT/CT indicate the direction in which clinical nuclear cardiology may be headed in the immediate future. To what extent nuclear cardiology will be passively absorbed by other modalities, or will actively incorporate other modalities, is up to the present and next generation of nuclear cardiologists

    Achieving competency at electrocardiogram (ECG) interpretation among cardiology subspecialty residents has traditionally focused on interpreting a target number of ECGs during training. However, there is little evidence to support this approach. Further, there are no data documenting the competency of ECG interpretation skills among cardiology residents, who become de facto the gold standard in their practice communities. We tested 29 Cardiology residents from all 3 years in a large training program using a set of 20 ECGs collected from a community cardiology practice over a 1-month period. Residents interpreted half of the ECGs using a standard analytic framework, and half using their own approach. Residents were scored on the number of correct and incorrect diagnoses listed. Overall diagnostic accuracy was 58%. Of 6 potentially life-threatening diagnoses, residents missed 36% (123 of 348) including hyperkalemia (81%), long QT (52%), complete heart block (35%), and ventricular tachycardia (19%). Residents provided additional inappropriate diagnoses on 238 ECGs (41%). Diagnostic accuracy was similar between ECGs interpreted using an analytic framework vs ECGs interpreted without an analytic framework (59% vs 58%; F(1,1333) = 0.26; P = 0.61). Cardiology resident proficiency at ECG interpretation is suboptimal. Despite the use of an analytic framework, there remain significant deficiencies in ECG interpretation among Cardiology residents. A more systematic method of addressing these important learning gaps is urgently needed. Copyright © 2014 Canadian Cardiovascular Society. Published by Elsevier Inc. All rights reserved.

    In this paper, we present a new generation of health services that has emerged due to the development of advanced information and communication technology (ICT) solutions, like the Enhanced Personal, Intelligent, and Mobile system for Early Detection and Interpretation of Cardiac Syndromes (EPI-MEDICS). It is a personal self-care system that allows any citizen to self-record high-quality ECGs on demand with a smart portable device, which is endowed with powerful ICT capabilities: self-adaptive embedded intelligence, mobile health record management support on SmartMedia card, embedded Web server, and wireless communication. The EPI-MEDICS solution design also provides ambient, intelligent, and pervasive computing services offering any citizen a ubiquitous, reliable, and efficient management of his/her own cardiac status. A multicentric evaluation performed in Europe with a series of device prototypes and the performance assessment of the original methods of signal synthesis that were designed to guarantee a high interoperability level of the recorded data within the clinical practice, as well as of the decision-support methodologies that were developed for an early detection of life-threatening myocardial ischemia and arrhythmia, at home or anywhere, demonstrate the pertinence of going toward a personal health society in cardiology, which still yields the highest mortality rate in industrialized countries.

    This review discusses the basics of cardiovascular gene therapy, the results of recent human clinical trials, and the rapid progress in imaging techniques in cardiology. Improved understanding of the molecular and genetic basis of coronary heart disease has made gene therapy a potential new alternative for the treatment of cardiovascular diseases. Experimental studies have established the proof-of-principle that gene transfer to the cardiovascular system can achieve therapeutic effects. First human clinical trials provided initial evidence of feasibility and safety of cardiovascular gene therapy. However, phase II/III clinical trials have so far been rather disappointing and one of the major problems in cardiovascular gene therapy has been the inability to verify gene expression in the target tissue. New imaging techniques could significantly contribute to the development of better gene therapeutic approaches. Although the exact choice of imaging modality will depend on the biological question asked, further improvement in image resolution and detection sensitivity will be needed for all modalities as we move from imaging of organs and tissues to imaging of cells and genes.

    Most contemporary 12-lead electrocardiogram (ECG) devices offer computerized diagnostic proposals. The reliability of these automated diagnoses is limited. It has been suggested that incorrect computer advice can influence physician decision-making. This study analyzed the role of diagnostic proposals in the decision process by a group of fellows of cardiology and other internal medicine subspecialties. A set of 100 clinical 12-lead ECG tracings was selected covering both normal cases and common abnormalities. A team of 15 junior Cardiology Fellows and 15 Non-Cardiology Fellows interpreted the ECGs in 3 phases: without any diagnostic proposal, with a single diagnostic proposal (half of them intentionally incorrect), and with four diagnostic proposals (only one of them being correct) for each ECG. Self-rated confidence of each interpretation was collected. Availability of diagnostic proposals significantly increased the diagnostic accuracy (p<0.001). Nevertheless, in case of a single proposal (either correct or incorrect) the increase of accuracy was present in interpretations with correct diagnostic proposals, while the accuracy was substantially reduced with incorrect proposals. Confidence levels poorly correlated with interpretation scores (rho≈2, p<0.001). Logistic regression showed that an interpreter is most likely to be correct when the ECG offers a correct diagnostic proposal (OR=10.87) or multiple proposals (OR=4.43). Diagnostic proposals affect the diagnostic accuracy of ECG interpretations. The accuracy is significantly influenced especially when a single diagnostic proposal (either correct or incorrect) is provided. The study suggests that the presentation of multiple computerized diagnoses is likely to improve the diagnostic accuracy of interpreters. Copyright © 2017 Elsevier B.V. All rights reserved.

    The complexity and potential biases involved in decision making have long been recognised and examined in both the aviation and business industries. More recently, the medical community have started to explore this concept and its particular importance in our field. Paediatric cardiology is a rapidly expanding field and for many of the conditions we treat, there is limited evidence available to support our decision-making. Variability exists within decision-making in paediatric cardiology and this may influence outcomes. There are no validated tools available to support and examine consistent decision-making for various treatment strategies in children with congenital heart disease in a multidisciplinary cardiology and cardiothoracic institution. Our primary objective was to analyse the complexity of decision-making for children with cardiac conditions in the context of our joint cardiology and cardiothoracic conference (JCC). Two paediatric cardiologists acted as investigators by observing the weekly joint cardiology-cardiothoracic surgery conference and prospectively evaluating the degree of complexity of decision-making in the management of 107 sequential children with congenital heart disease discussed. Additionally, the group consensus on the same patients was prospectively assessed to compare this to the independent observers. Of 107 consecutive children discussed at our JCC conference 32 (27%) went on to receive surgical intervention, 20 (17%) underwent catheterisation and 65 (56%) received medical treatment. There were 53 (50%) cases rated as simple by one senior observer, while 54 (50%) were rated as complex to some degree. There was high inter-observer agreement with a Krippendorff's alpha of ≥ 0.8 between 2 observers and between 2 observers and the group consensus as a whole for grading of the complexity of decision-making. Different decisions were occasionally made on patients with the same data set. Discussions revisiting the same patient, in

    Evidence-based medicine has contributed substantially to the quality of medical care in pediatric and adult cardiology. However, our impression from the bedside is that a substantial number of Cochrane reviews generate inconclusive data that are of limited clinical benefit. We performed a systematic synopsis of Cochrane reviews published between 2001 and 2015 in the field of pediatric cardiology. Main outcome parameters were the number and percentage of conclusive, partly conclusive, and inconclusive reviews as well as their recommendations and their development over three a priori defined intervals. In total, 69 reviews were analyzed. Most of them examined preterm and term neonates (36.2%), whereas 33.3% included also non-pediatric patients. Leading topics were pharmacological issues (71.0%) followed by interventional (10.1%) and operative procedures (2.9%). The majority of reviews were inconclusive (42.9%), while 36.2% were conclusive and 21.7% partly conclusive. Although the number of published reviews increased during the three a priori defined time intervals, reviews with "no specific recommendations" remained stable while "recommendations in favor of an intervention" clearly increased. Main reasons for missing recommendations were insufficient data (n = 41) as well as an insufficient number of trials (n = 22) or poor study quality (n = 19). There is still need for high-quality research, which will likely yield a greater number of Cochrane reviews with conclusive results.

    Depression and anxiety are common among patients with cardiovascular disease (CVD) and confer significant cardiac risk, contributing to CVD morbidity and mortality. Unfortunately, due to the lack of screening tools that address the specific needs of hospitalized patients, few cardiac inpatient programs offer routine screening for these forms of psychological distress, despite recommendations to do so. The purpose of this study was to validate single-item measures for depression and anxiety among cardiac inpatients. Consecutive inpatients were recruited from the cardiology and cardiac surgery step-down units at a university-affiliated, quaternary-care hospital. Subjects completed a questionnaire that included: (a) demographics, (b) single-item-measures for depression and anxiety (from the Screening Tool for Psychological Distress (STOP-D)), and (c) Hospital Anxiety and Depression Scale (HADS). One hundred and five participants were recruited with a wide variety of cardiac diagnoses, having a mean age of 66 years, and 28% were women. Both STOP-D items were highly correlated with their corresponding validated measures and demonstrated robust receiver-operator characteristic curves. Severity scores on both items correlated well with established severity cut-off scores on the corresponding subscales of the HADS. The STOP-D is a self-administered, self-report measure using two independent items that provide severity scores for depression and anxiety. The tool performs very well compared with other previously validated measures. Requiring no additional scoring and being free, STOP-D offers a simple and valid method for identifying hospitalized cardiac patients who are experiencing psychological distress. This crucial first step triggers initiation of appropriate monitoring and intervention, thus reducing the likelihood of the adverse cardiac outcomes associated with psychological distress. © The European Society of Cardiology 2014.

    Interventional radiology is one of the medical specialties that provides the highest doses to professionals, widely used in cardiology, being called interventional cardiology. In order to contribute to the optimization of occupational radiation protection in interventional cardiology procedures, the aim of this study is to evaluate the dose estimation received in different body regions by physicians in interventional cardiology procedures. Two physicians were followed, named as A and B, during one month period, performing a total of 127 procedures (70 for A and 57 for B) of interventional cardiology. During the procedures, dosimeters in different body regions beyond the full-body dosimeter were positioned. The results showed the highest values for the estimated dose received by workers were in the right wrist and left side face regions, for the physician A, and in the left knee and left side face, for the physician B. Results demonstrate the importance of using individual protection equipment by physicians in interventional cardiology, including lead glasses, besides monitoring dosimeters for other body regions, such as wrist, face and knee.

    Appointed jointly by the Portuguese Society of Cardiothoracic and Vascular Surgery (SPCCTV) and the Portuguese Society of Cardiology (SPC), the Working Group on Waiting Times for Cardiac Surgery was established with the aim of developing practical recommendations for clinically acceptable waiting times for the three critical phases of the care of adults with heart disease who require surgery or other cardiological intervention: cardiology appointments; the diagnostic process; and invasive treatment. Cardiac surgery has specific characteristics that are not comparable to other surgical specialties. It is important to reduce maximum waiting times and to increase the efficacy of systems for patient monitoring and tracking. The information in this document is mainly based on available clinical information. The methodology used to establish the criteria was based on studies on the natural history of heart disease, clinical studies comparing medical treatment with intervention, retrospective and prospective analyses of patients on waiting lists, and the opinions of experts and working groups. Following the first step, represented by publication of this document, the SPCCTV and SPC, as the bodies best suited to oversee this process, are committed to working together to define operational strategies that will reconcile the clinical evidence with the actual situation and with available resources.

    The population of older adults is expanding rapidly and aging predisposes to cardiovascular disease. The principle of patient-centered care must respond to the preponderance of cardiac disease that now occurs in combination with complexities of old age. Geriatric cardiology melds cardiovascular perspectives with multimorbidity, polypharmacy, frailty, cognitive decline, and other clinical, social, financial, and psychological dimensions of aging. While some assume a cardiologist may instinctively cultivate some of these skills over the course of a career, we assert that the volume and complexity of older cardiovascular patients in contemporary practice warrants a more direct approach to achieve suitable training and a more reliable process of care. We present a rationale and vision for geriatric cardiology as a melding of primary cardiovascular and geriatrics skills, and thereby infusing cardiology practice with expanded proficiencies in diagnosis, risks, care coordination, communications, end-of-life, and other competences required to best manage older cardiovascular patients.

    Frailty is a clearly emerging theme in acute care medicine, with obvious prognostic and health resource implications. "Frailty" is a term used to describe a multidimensional syndrome of loss of homeostatic reserves that gives rise to a vulnerability to adverse outcomes after relatively minor stressor events. This is conceptually simple, yet there has been little consensus on the operational definition. The gold standard method to diagnose frailty remains a comprehensive geriatric assessment; however, a variety of validated physical performance measures, judgement-based tools, and multidimensional scales are being applied in critical care, cardiology, and cardiac surgery settings, including open cardiac surgery and transcatheter aortic value replacement. Frailty is common among patients admitted to the intensive care unit and correlates with an increased risk for adverse events, increased resource use, and less favourable patient-centred outcomes. Analogous findings have been described across selected acute cardiology and cardiac surgical settings, in particular those that commonly intersect with critical care services. The optimal methods for screening and diagnosing frailty across these settings remains an active area of investigation. Routine assessment for frailty conceivably has numerous purported benefits for patients, families, health care providers, and health administrators through better informed decision-making regarding treatments or goals of care, prognosis for survival, expectations for recovery, risk of complications, and expected resource use. In this review, we discuss the measurement of frailty and its utility in patients with critical illness and in cardiology and cardiac surgery settings.

    Rising health care costs above inflation are placing serious strains on the sustainability of the Australian Medicare system in its current structure. The Medicare Benefits Schedule (MBS), which lists rebates payable to patients for private medical services provided on a fee-for-service basis, is the cornerstone of the Australian health care system. Introduced in the 1980s, the MBS has changed little despite major advances in the evidence base for the practice of cardiology. We outline how we believe sensible changes to the MBS listings for four cardiac services--invasive coronary angiography, computed tomography coronary angiography, stress testing and percutaneous coronary intervention--would improve the clinical practice of cardiology and save substantial amounts of taxpayer money.

    This paper presents data on the nascence and development of the interventional cardiology service in Kazakhstan. It provides details of the structure of the Kazakhstan interventional cardiology service, staff training, the number of coronary and structural heart interventions for the period of 2010-2015, as well as the peculiarities of the capitation payment method. The number of coronary interventions is increasing year by year, though the number of intracoronary imaging techniques and intracoronary flow/pressure techniques remains inadequate. Structural heart interventions are mostly performed at tertiary hospital level, with an ever increasing number of transcatheter aortic valve implantation (TAVI) procedures.

    Abstract Objective  To describe the evidence about factors influencing breast cancer patients’ surgery choices and the implications for designing decision support in reference to an extended Theory of Planned Behaviour (TPB) and the Common Sense Model of Illness Representations (CSM). Background  A wide range of factors are known to influence the surgery choices of women diagnosed with early breast cancer facing the choice of mastectomy or breast conservation surgery with radiotherapy. However, research does not always reflect the complexities of decision making and is often atheoretical. A theoretical approach, as provided by the CSM and the TPB, could help to identify and tailor support by focusing on patients’ representations of their breast cancer and predicting surgery choices. Design  Literature search and narrative synthesis of data. Synthesis  Twenty‐six studies reported women’s surgery choices to be influenced by perceived clinical outcomes of surgery, appearance and body image, treatment concerns, involvement in decision making and preferences of clinicians. These factors can be mapped onto the key constructs of both the TPB and CSM and used to inform the design and development of decision support interventions to ensure accurate information is provided in areas most important to patients. Conclusions  The TPB and CSM have the potential to inform the design of decision support for breast cancer patients, with accurate and clear information that avoids leading patients to make decisions they may come to regret. Further research is needed examining how the components of the extended TPB and CSM account for patients’ surgery choices. PMID:20579123

    Advanced Practice Providers (APPs) can fill access to care gaps created by physician shortages and improve adherence/compliance with preventive atherosclerotic cardiovascular disease (ASCVD) interventions. We retrospectively reviewed data on 595 patients enrolled in a preventive cardiology clinic (PCC) utilizing APPs compared with a propensity-matched cohort (PMC) of 595 patients enrolled in primary care clinics alone. PCC patients were risk stratified using Framingham risk scoring (FRS) and coronary artery calcium scoring (CACS) and treated based on published guideline-based algorithms. Baseline demographics were well balanced between the groups. CACS was more commonly obtained in PCC patients (p<0.001) resulting in reclassification of 30.6% patients to a higher risk category, including statin therapy in 26.6% of low FRS PCC patients with CACS ≥75 th MESA percentile. Aspirin initiation was higher for high and intermediate FRS patients in the PCC (p <0.001). Post-intervention mean LDL, non-HDL, and triglycerides (all p<0.05) were lower in the PCC group. Compliance with appropriate lipid treatment was higher in intermediate to high FRS patients (p=0.004) in the PCC group. Aggressive LDL and non-HDL treatment goals <70mg/dL (p=0.005) and <130mg/dL (p<0.001), respectively, were more commonly achieved in high FRS PCC patients. Median post-intervention SBP was lower amongst intermediate and low FRS patients (p=0.001 & p<0.001, respectively). Cumulatively, this resulted in a reduction in median post-intervention PCC FRS across all initial FRS risk categories (p<0.001 for all). APPs within a preventive cardiology clinic effectively risk stratify and aggressively manage ASCVD risk factors resulting in a reduction in post-intervention FRS.

    Cardiology fellowship programs are at the interface of medical education and the care of patients suffering from the leading cause of mortality in the United States, yet there is an apparent lack of research guiding the effective education of fellows. We sought to quantify the number of publications in cardiology journals that pertained to the education of cardiology trainees and the number of cardiologists participating in education research. For the period between January and December 2012, we cataloged cardiology-specific and general medical/medical education journals and sorted them by impact factor. Tables of content were reviewed for articles with an educational focus, a cardiology focus, or both. We recorded the authors' areas of medical training, and keywords from each cardiology journal's mission statement were reviewed for emphasis on education. Twenty-six cardiology journals, containing 6645 articles, were reviewed. Only 4 articles had education themes. Ten general medical and 15 medical education journals contained 6810 articles. Of these, only 7 focused on medical education in cardiology, and none focused on cardiology fellowship training. Among the 4887 authors of publications in medical education journals, 25 were cardiologists (less than 1%), and among the 1036 total words in the mission statements of all cardiology journals, the term "education" appeared once. Published educational research is lacking in cardiology training, and few cardiologists appear to be active members of the education scholarship community. Cardiology organizations and academic journals should support efforts to identify target areas of study and publish scholarship in educational innovation.

    Analysis of the underlying causes of death can develop action plans for prevention of death that could be avoided. The aim of our study was to analyse the causes of cardiovascular deaths in the cardiology department of Yalgado Ouedraogo University Hospital. The study was a descriptive retrospective study over a 24 month period among patients who died in the department. Prevalence of death in the cardiology department was of 13.2%. Sex ratio was of 1.2 and 72.7% of patients were residing in Ouagadougou. Mean age of patients was 56.1 years and 59.4% of patients were under 65 years old. Hypertension was the major cardiovascular risk factor (46.1%) and 27.4% of patients had a medical history of dilated cardiomyopathy. Cardiogenic shock was the immediate cause of death in 55.5% of cases and the initial cause of death was hypertension and its complications in 46.1% of cases. Death was not notified in 18% of cases and no death had been medically certified. Death statistics are the most reliable data for public health interventions. However, it is necessary to establish an effective method of data gathering according to the WHO standards in order to facilitate international comparison.

    Mexico has been positioned as the country with the highest mortality attributed to myocardial infarction among the members of the Organization for Economic Cooperation and Development. This rate responds to multiple factors, including a low rate of reperfusion therapy and the absence of a coordinated system of care. Primary angioplasty is the reperfusion method recommended by the guidelines, but requires multiple conditions that are not reached at all times. Early pharmacological reperfusion of the culprit coronary artery and early coronary angiography (pharmacoinvasive strategy) can be the solution to the logistical problem that primary angioplasty rises. Several studies have demonstrated pharmacoinvasive strategy as effective and safe as primary angioplasty ST-elevation myocardial infarction, which is postulated as the choice to follow in communities where access to PPCI is limited. The Mexico City Government together with the National Institute of Cardiology have developed a pharmaco-invasive reperfusion treatment program to ensure effective and timely reperfusion in STEMI. The model comprises a network of care at all three levels of health, including a system for early pharmacological reperfusion in primary care centers, a digital telemedicine system, an inter-hospital transport network to ensure primary angioplasty or early percutaneous coronary intervention after fibrinolysis and a training program with certification of the health care personal. This program intends to reduce morbidity and mortality associated with myocardial infarction. Copyright © 2016 Instituto Nacional de Cardiología Ignacio Chávez. Publicado por Masson Doyma México S.A.

    Everolimus, a proliferation signal inhibitor in the mammalian target of rapamycin (mTOR) drug class, has many clinical applications, including in organ transplantation, oncology, and cardiology. It currently has United States Food and Drug Administration (FDA) approval for prophylaxis against rejection in de novo renal transplant recipients, treatment of renal cell carcinoma, and use as a drug-eluting stent. To review the pharmacology, pharmacokinetics, efficacy, and safety of everolimus, we performed a search of the MEDLINE database (January 1997-April 2010) for all English-language articles of in vitro and in vivo studies that evaluated everolimus, as well as abstracts from recent scientific meetings and the manufacturer. In transplantation, everolimus demonstrates immunosuppressive properties and has been used to prevent acute rejection in cardiac, liver, lung, and renal transplant recipients. It appears that this agent may be potent enough to allow for the minimization or removal of calcineurin inhibitors in the long-term management of renal transplant recipients. In oncology, everolimus has been proven effective for the management of treatment-resistant renal cell carcinoma. In cardiology, everolimus is available as a drug-coated stent and is used in percutaneous coronary interventions for prevention of restenosis. In transplant recipients and patients with renal cell carcinoma, everolimus appears to have an extensive adverse-event profile. The pharmacologic properties of everolimus differentiate this agent from other drugs used in these clinical areas, and its pharmacokinetic properties differentiate it from sirolimus.

    The population of older adults is expanding rapidly, and aging predisposes to cardiovascular disease. The principle of patient-centered care must respond to the preponderance of cardiac disease that now occurs in combination with the complexities of old age. Geriatric cardiology melds cardiovascular perspectives with multimorbidity, polypharmacy, frailty, cognitive decline, and other clinical, social, financial, and psychological dimensions of aging. Although some assume that a cardiologist may instinctively cultivate some of these skills over the course of a career, we assert that the volume and complexity of older cardiovascular patients in contemporary practice warrants a more direct approach to achieve suitable training and a more reliable process of care. We present a rationale and vision for geriatric cardiology as a melding of primary cardiovascular and geriatrics skills, thereby infusing cardiology practice with expanded proficiencies in diagnosis, risks, care coordination, communications, end-of-life, and other competences required to best manage older cardiovascular patients.

    Tele-echocardiography has the potential to bring real-time diagnoses to neonatal facilities without in-house pediatric cardiologists. Many neonates in rural areas, smaller cities, and community hospitals do not have immediate access to pediatric sonographers or echocardiogram interpretation by pediatric cardiologists. This can result in suboptimal echocardiogram quality, delay in initiation of medical intervention, unnecessary patient transport, and increased medical expenditures. Telemedicine has been used with increased frequency to improve efficiency of pediatric cardiology care in hospitals that are not served by pediatric cardiologists. Initial reports suggest that telecardiology is accurate, improves patient care, is cost-effective, enhances echocardiogram quality, and prevents unnecessary transports of neonates in locations that are not served by pediatric cardiologists. We report the largest series to evaluate the impact of telemedicine on delivery of pediatric cardiac care in community hospitals. We hypothesized that live telemedicine guidance and interpretation of neonatal echocardiograms from community hospitals is accurate, improves patient care, enhances sonographer proficiency, allows for more efficient physician time management, increases patient referrals, and does not result in increased utilization of echocardiography. Using desktop videoconferencing computers, pediatric cardiologists guided and interpreted pediatric echocardiograms from 2 community hospital nurseries 15 miles from a tertiary care center. Studies were transmitted in real-time using the H.320 videoconferencing protocol over 3 integrated services digital network lines (384 kilobits per second). This resulted in a frame rate of 23 to 30 frames per second. Sonographers who primarily scanned adult patients but had received additional training in echocardiography of infants performed the echocardiograms. Additional views were suggested as deemed necessary by the interpreting physician

    In Cardiovascular Rehabilitation the increasing inpatients complexity suggests the necessity to develop screening methods which allow to identify those patients that require a psychological intervention. A Psycho-Cardiological Schedule (PCS) was developed with the aim of detecting the critical situation indicators or the presence of psychological, social and cognitive problems. The PCS, compiled by a nurse or cardiologist in collaboration with a psychologist, allows to assess the need for a deeper psychological examination, clinical and/or with tests. Aim of the present study is to identify the convergence levels among the observational and anamnestic data of the PCS collected by a nurse and the clinical and/or test data of the psychological deeper assessment. Among the 87 patients recruited in January-February 2010, 28 (aged 53.5 +/- 12.6, M = 20, F = 8) fulfilled the criteria for a deeper psychological examination: age psychological/behavioural problems, neuropsychological disorders, low adherence to prescriptions, inadequate disease knowledge/representation. From data comparisons emerged convergence levels with 100% concordance as to smoke habits and problems in social-family support. High convergence levels also resulted as to emotional and/or behavioural problems (92.8%) and inadequate adherence to prescriptions (89.3%). Lower levels of concordance (82.1%) emerged when considering disease knowledge/representation, issues specifically linked to cognition and subjective illness experience, not directly detectable from behaviour. our data confirm the synergic efficacy of the two evaluations: the Psycho-Cardiological Schedule reliably identifies the problematic macro-categories, mainly if they are characterized by behavioural indicators, which facilitate the detection. The psychological approach appears more suitable for better specifing macro-categories characteristics and for detecting critical aspects not overt but not less important, providing therefore advice

    The role of women and foreign medical graduates (FMGs) in cardiology research published in the United States has received limited study. We examined the characteristics of the first and last authors of all original contributions and review articles published in the Journal of the American College of Cardiology from October 1, 2015, to October 1, 2016. A total of 345 articles were identified, with 687 first and last authors originating from ≥50 different countries. Overall, 17% of authors were women (20% of the first and 14% of the last authors). Overall, 86% of authors held a medical degree (MD) or equivalent, and 25% of those also held another advanced degree (PhD, MPH, and/or MBA). The proportion of authors with an advanced degree in addition to an MD/equivalent was higher among foreign graduates and international contributors as compared with American graduates (31% vs. 30% vs. 17%, respectively, p < 0.0001). Of US-based authors with an MD/equivalent, 67% were American medical graduates (AMGs) and 33% were FMGs. Women authors represented 11% of FMGs, 16% of AMGs, and 12% of international physicians as contributors (p = 0.23). Foreign graduates and international researchers contribute substantially to cardiology research in the US, but women authors remain under-represented. Copyright © 2018 Hellenic Society of Cardiology.

    2008-01-01

    The evaluation of dose to physicians involved in Interventional Cardiology (IC) is an extreme important matter due to the high and non-uniform distribution of dose values. The radiation control during each procedure is complex and the reasons for the high exposures have many different causes. Many international recommendations have already been written aiming the radiation protection optimization in IC. In Brazil, there is not any special orientation for the protection of those occupational persons, nor a specific legislation. The purpose of this work is to evaluate the air kerma rate at critical anatomic regions of the occupationally exposed staff that carry out IC procedures, in representative incidences in order to give subsidies for individual monitoring procedures implementation and to give more information about their radiation protection. The air kerma rate has been measured in the often used condition in the two more common IC procedures namely angiography and coronary angioplasty, using an adult patient simulator irradiated under RAO, LAO and AP projections for fluoro and digital acquisition modes. The measurements have been made in 45 points around the examination table at 5 different representatives heights of: eyes lens, thorax, hands, gonads and knees. AP projection shows the smaller scattered radiation contributions and a more homogeneous exposure distribution. The digital acquisition mode gives air kerma rates about 4 times higher than fluoro mode for LAO projection in the position occupied by the interventionist doctor, the anesthetist and the nursing staff. The most critical anatomic regions are: knees and gonads (without protection). On the physician hands position, values as high as 5 mGy/h have been measured, which can overpass, depending on the number of procedures done, the individual occupational annual limit. Therefore, in IC it is necessary to implement additional protection tools, elaborate safety guides (based on international experiences

    Community based registries are particularly valuable tools to Preventive Cardiology as they summarize epidemiological data of ischemic heart disease risk factors, medications and lifestyle characteristics. We enrolled 1191 patients, from an outpatient community based cardiology network, dedicated to cover medically, office based professionals. We recorded demographic and lifestyle characteristics, risk factors for ischemic heart disease, all clinical entities diagnosed and therapies which were prescribed for hypertension and lipid disorders specifically. Our population consisted of 659 males (55%) and 532 females (45%), (mean age 46±14). A sedentary lifestyle was almost universal (92%), followed by smoking (44%) and overweight body composition (38%). Unhealthy lifestyle increased significantly during the third decade of life, while multimorbidity ascended during the fifth. Cardiovascular morbidity was present in 611 patients (51%), while 289 patients (24%) were found negative for cardiovascular disease and positive for a different system diagnosis. Lipid disorders (32%) and hypertension (31%) were the most frequent cardiovascular entities. β-Blockers and statins were the most frequently prescribed medications for hypertension and lipid disorders respectively. Cardiovascular morbidity was frequent in this ambulatory middle aged population, whereas multimorbidity (mainly from gastrointestinal and endocrine system) was a significant coexisting problem, even for a cardiology oriented outpatient population. Unhealthy lifestyle is of major importance because it was present in the majority of our patients early in their life and because it was statistically related to hyperlipidemia and hypertension. Preventive Cardiology must introduce special interventions to deescalate the presence of unhealthy lifestyle in young populations. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available OBJECTIVE: To evaluate the management of patients complaining of high blood pressure (BP in a cardiological emergency room. METHODS: Patients referred to the cardiological emergency room with the main complaint of high blood pressure were consecutively selected. The prescriptions and the choice of antihypertensive drugs were assessed. The classification of these patients as hypertensive emergencies or pseudoemergencies, according to the physician who provided initial care, was recorded. RESULTS: From a total of 858 patients presenting to the emergency room, 80 (9.3% complained of high BP, and 61 (76.3% received antihypertensive drugs. Sublingual nifedipine was the most commonly used drug (59%. One patient received intravenous medication, one patient was hospitalized and 6 patients (7.5% were classified as hypertensive emergencies or pseudoemergencies. CONCLUSION: High BP could seldom be classified as a hypertensive emergency or pseudoemergency, even though it was a frequent complaint (9.3% of visits. Currently, the therapeutic approach is not recommended, even in specialized clinics.

  15. Is patient size important in dose determination and optimization in cardiology?

    Reay, J; Chapple, C L; Kotre, C J

    2003-01-01

    Patient dose determination and optimization have become more topical in recent years with the implementation of the Medical Exposures Directive into national legislation, the Ionising Radiation (Medical Exposure) Regulations. This legislation incorporates a requirement for new equipment to provide a means of displaying a measure of patient exposure and introduces the concept of diagnostic reference levels. It is normally assumed that patient dose is governed largely by patient size; however, in cardiology, where procedures are often very complex, the significance of patient size is less well understood. This study considers over 9000 cardiology procedures, undertaken throughout the north of England, and investigates the relationship between patient size and dose. It uses simple linear regression to calculate both correlation coefficients and significance levels for data sorted by both room and individual clinician for the four most common examinations, left ventrical and/or coronary angiography, single vessel stent insertion and single vessel angioplasty. This paper concludes that the correlation between patient size and dose is weak for the procedures considered. It also illustrates the use of an existing method for removing the effect of patient size from dose survey data. This allows typical doses and, therefore, reference levels to be defined for the purposes of dose optimization

    The term "onco-cardiology" has been used in reference to cardiotoxicity in the treatment of malignant disease. In actual clinical situations, however, cardiovascular disease (CVD) associated with malignant disease and the concurrence of atherosclerotic disease with malignant disease are commonly observed, complicating the course of treatment. Patients with malignant disease associated with coronary artery disease often die from the cardiovascular disease, so it is essential to classify these disease states. Additionally, the prevalence of these classifications makes it easy to manage patients with malignant disease and coronary artery disease. We divided the broad field of onco-cardiology into 4 classifications based on clinical scenarios (CSs): CS1 represents the so-called paraneoplastic syndrome. CS2 represents cardiotoxicity during treatment of malignant diseases. CS3 represents the concurrence of atherosclerotic disease with malignant disease, and CS4 represents cardiovascular disease with benign tumors. This classification facilitates the management of patients with malignant disease and coronary artery disease by promoting not only the primary but also the secondary prevention of CVD.

    Common mental disorders (CMDs) cause great individual suffering and long-term sick leave. Cognitive-behavioural therapy (CBT) effectively treats CMDs, but sick leave is not reduced to the same extent as psychiatric symptoms. Research results regarding return-to-work interventions (RTW-Is) and their effect on sick leave are inconclusive. The aim of this study was to evaluate CBT, a RTW-I and combined CBT and RTW-I (COMBO) for primary care patients on sick leave due to CMDs. Patients with CMDs (n=211) were randomised to CBT (n=64), RTW-I (n=67) or COMBO (n=80). Sick-leave registry data after 1 year and blinded Clinician's Severity Rating (CSR) of symptoms post-treatment and at follow-ups after 6 and 12 months were primary outcomes. There was no significant difference between treatments in days on sick leave 1 year after treatment start (mean difference in sick-leave days range=9-27). CBT led to larger reduction of symptoms post-treatment (CSR; Cohen's d=0.4 (95% CI 0.1 to 0.8)) than RTW-I, whereas COMBO did not differ from CBT or RTW-I. At follow-up, after 1 year, there was no difference between groups. All treatments were associated with large pre-treatment to post-treatment improvements, and results were maintained at 1-year follow-up. No treatment was superior to the other regarding reducing sick leave. All treatments effectively reduced symptoms, CBT in a faster pace than RTW-I, but at 1-year follow-up, all groups had similar symptom levels. Further research is needed regarding how CBT and RTW-I can be combined more efficiently to produce a larger effect on sick leave while maintaining effective symptom reduction. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Summary Background Statins reduce coronary events in patients with coronary artery disease. Material/Methods Chart reviews were performed in 305 patients (217 men and 88 women, mean age 74 years) not treated with statins during the first year of being seen in an outpatient cardiology practice but subsequently treated with statins. Based on the starting date of statins use, the long-term outcomes of myocardial infarction (MI), percutaneous coronary intervention (PCI), and coronary artery bypass graft surgery (CABGS) before and after statin use were compared. Results Mean follow-up was 65 months before statins use and 66 months after statins use. MI occurred in 31 of 305 patients (10%) before statins, and in 13 of 305 patients (4%) after statins (pcardiology practice reduces the incidence of MI, PCI, and CABGS. PMID:22129898

    2002-01-01

    A questionnaire was sent to 251 nuclear medicine centres asking for details of nuclear medicine activity, and nuclear cardiology activity and practice in 1997. One hundred and seventy-one (68%) centres replied. Nuclear medicine activity was estimated at 11.8 studies/1,000 population/year, and 9.5% of these studies were within cardiology (1.12 studies/1,000/year). Myocardial perfusion imaging (MPI) studies accounted for 77% and radionuclide ventriculography (RNV) for 22% of all nuclear cardiology. On a national basis this represents activity levels of 0.86 and 0.25 studies/1,000/year for MPI and RNV, respectively. Of the 171 responding centres, 102 (60%) performed MPI studies and 81 (79%) of these reported that activity was increasing. However, MPI activity was unevenly distributed between hospitals. Two centres accounted for 13% of total MPI; others had far lower activity rates, and 51/102 (50%) centres performed less than 200 MPI studies/year. Comparison with previous surveys showed that nuclear medicine activity had almost doubled since 1990 (it was 6.0 studies/1,000 population in 1990, 9.3 studies/1,000 in 1994 and 11.8 studies/1,000 in 1997). Over the same period, nuclear cardiology activity had also risen, the greatest increase being seen for the last 3 years (it was 0.7 studies/1,000 population in 1990, 0.82 studies/1,000 in 1994 and 1.12 studies/1,000 in 1997). Despite these encouraging figures, MPI activity for 1997 remained well below that recommended by the British Cardiac Society in 1994 (2.6 studies/1,000/year) as adequate to serve the needs of patients with cardiac disease in the UK; it was also below the European average activity for the same year (2.2 studies/1,000/year). The anticipated increased workload for nuclear cardiology is encouraging despite the wide and varied practice of nuclear cardiology around the UK. The nuclear medicine community now needs to address the issues that will prevent it keeping up with demand, such as restricted camera

    An office computer is a utility, like an automobile, with benefits and costs that are both direct and hidden and potential for disaster. For the cardiologist or cardiovascular surgeon, the increasing power and decreasing costs of computer hardware and the availability of software make use of an office computer system an increasingly attractive possibility. Management of office business functions is common; handling and scientific analysis of practice medical information are less common. The cardiologist can also access national medical information systems for literature searches and for interactive further education. Selection and testing of programs and the entire computer system before purchase of computer hardware will reduce the chances of disappointment or serious problems. Personnel pretraining and planning for office information flow and medical information security are necessary. Some cardiologists design their own office systems, buy hardware and software as needed, write programs for themselves and carry out the implementation themselves. For most cardiologists, the better course will be to take advantage of the professional experience of expert advisors. This article provides a starting point from which the practicing cardiologist can approach considering, specifying or implementing an office computer system for business functions and for scientific analysis of practice results.

    Full Text Available There is a growing need worldwide to take medical care to distant locations far from the main urban centers, particularly to rural areas. Furthermore, there is the ethical imperative to provide equal access to medical care to all patients, regardless of their place of residence, so as to satisfy an increasingly demanding population. A widespread problem, from which cardiology is not excepted, is the insufficient number of specialists and their uneven distribution. The upsurge in information and communications technology has made available a large collection of tools, mainly computers, smartphones, e-mail, and the Internet, to name just a few, to meet the needs of communication between individuals and organizations. This article defines telemedicine and describes its application in the practice of cardiology and its impact in Chile.

  6. Nuclear cardiology: Myocardial perfusion and function

    1991-01-01

    Myocardial perfusion studies continue to be a major focus of research, with new investigations of the relationship of exercise-redistribution thallium imaging to diagnosis, prognosis, and case management. The redistribution phenomenon, which seemed to be fairly well understood a few years ago, is now recognized to be much more complex than originally thought, and various strategies have been proposed to clarify the meaning of persistent defects. Pharmacologic intervention with dipyridamole and adenosine has become available as an alternative to exercise, and comparisons with exercise imaging and catheterization results have been described. Thallium itself is no longer the sole single-photon perfusion radiopharmaceutical; two new technetium agents are now widely available. In addition to perfusion studies, advances in the study of ventricular function have been made, including reports of studies performed in conjunction with technetium perfusion studies, new insights into cardiac physiology, and the prognostic and case-management information that function studies provide. Finally, work has continued with monoclonal antibodies for the identification of areas of myocyte necrosis. 41 references

    Workforce experts predict a future shortage of cardiologists that is expected to impact rural areas more severely than urban areas. However, there is little research on how rural patients are currently served through clinical outreach. This study examines the impact of cardiology outreach in Iowa, a state with a large rural population, on participating cardiologists and on patient access. Outreach clinics are tracked annually in the Office of Statewide Clinical Education Programs Visiting Medical Consultant Database (University of Iowa Carver College of Medicine). Data from 2014 were analyzed. In 2014, an estimated 5460 visiting consultant clinic days were provided in 96 predominantly rural cities by 167 cardiologists from Iowa and adjoining states. Forty-five percent of Iowa cardiologists participated in rural outreach. Visiting cardiologists from Iowa and adjoining states drive an estimated 45 000 miles per month. Because of monthly outreach clinics, the average driving time to the nearest cardiologist falls from 42.2±20.0 to 14.7±11.0 minutes for rural Iowans. Cardiology outreach improves geographic access to office-based cardiology care for more than 1 million Iowans out of a total population of 3 million. Direct travel costs and opportunity costs associated with physician travel are estimated to be more than $2.1 million per year. Cardiologists in Iowa and adjoining states have expanded access to office-based cardiology care from 18 to 89 of the 99 counties in Iowa. In these 71 counties without a full-time cardiologist, visiting consultant clinics can accommodate more than 50% of office visits in the patients' home county. © 2016 The Authors.

    Cardiac e-consults may be an effective way to deliver value-oriented outpatient cardiology care in an accountable care organization. Initial results of cardiac e-consults have demonstrated high satisfaction among both patients and referring providers, no known adverse events, and low rates of diagnostic testing. Nevertheless, differences between e-consults and traditional consults, effects of e-consults on traditional consult volume, and whether patients seek traditional consults after e-consults are unknown. We established a cardiac e-consult program on January 13, 2014. We then conducted detailed medical record reviews of all patients with e-consults to detect any adverse clinical events and detect subsequent traditional visits to cardiologists. We also performed 2 comparisons. First, we compared age, gender, and referral reason for e-consults vs traditional consults. Second, we compared changes in volume of referrals to cardiology vs other medical specialties that did not have e-consults. From January 13 to December 31, 2014, 1,642 traditional referrals and 165 e-consults were requested. The proportion of e-consults of all evaluations requested over that period was 9.1%. Gender balance was similar among traditional consults and e-consults (44.8% male for e-consults vs 45.0% for traditional consults, P = .981). E-consult patients were younger than traditional consult patients (55.3 vs 60.4 years, P cardiology visit during the follow-up period. E-consults are an effective and safe mechanism to enhance value in outpatient cardiology care, with low rates of bounceback to traditional consults. E-consults can account for nearly one-tenth of total outpatient consultation volume at 1 year within an accountable care organization and are associated with a reduction in traditional referrals to cardiologists.

    In 2012, the American College of Cardiology's (ACC) Adult Congenital and Pediatric Cardiology Council established a program to develop quality metrics to guide ambulatory practices for pediatric cardiology. The council chose five areas on which to focus their efforts; chest pain, Kawasaki Disease, tetralogy of Fallot, transposition of the great arteries after arterial switch, and infection prevention. Here, we sought to describe the process, evaluation, and results of the Infection Prevention Committee's metric design process. The infection prevention metrics team consisted of 12 members from 11 institutions in North America. The group agreed to work on specific infection prevention topics including antibiotic prophylaxis for endocarditis, rheumatic fever, and asplenia/hyposplenism; influenza vaccination and respiratory syncytial virus prophylaxis (palivizumab); preoperative methods to reduce intraoperative infections; vaccinations after cardiopulmonary bypass; hand hygiene; and testing to identify splenic function in patients with heterotaxy. An extensive literature review was performed. When available, previously published guidelines were used fully in determining metrics. The committee chose eight metrics to submit to the ACC Quality Metric Expert Panel for review. Ultimately, metrics regarding hand hygiene and influenza vaccination recommendation for patients did not pass the RAND analysis. Both endocarditis prophylaxis metrics and the RSV/palivizumab metric passed the RAND analysis but fell out during the open comment period. Three metrics passed all analyses, including those for antibiotic prophylaxis in patients with heterotaxy/asplenia, for influenza vaccination compliance in healthcare personnel, and for adherence to recommended regimens of secondary prevention of rheumatic fever. The lack of convincing data to guide quality improvement initiatives in pediatric cardiology is widespread, particularly in infection prevention. Despite this, three metrics were

    Full Text Available Abstract Background Evidence has shown that children 0-4 year-old attending childcare are prone to acquire infections compared to children cared for at home, with fever being the most common symptom. Illness absenteeism due to fever and common infections is substantial and mostly driven by unrealistic concerns and negative attitude towards fever of both childcare staff and parents, resulting in illness absenteeism from childcare, work absenteeism among parents and healthcare service use. The objective of this study is to optimise decision making among childcare staff on illness absenteeism due to fever and common infections in childcare. Underlying determinants of behavioural change were targeted by means of a multicomponent intervention. Methods A multicomponent intervention was developed to improve decision making, using the stepwise approach of Intervention Mapping, and in close collaboration with stakeholders and experts. The intervention consisted of 1 a two-hour educational session on fever among childcare staff; 2 an online video for childcare staff and parents emphasising key information of the educational session; 3 a decision tool for childcare staff and parents in the format of a traffic light system to estimate the severity of illness and corresponding advices for childcare staff and parents; 4 an information booklet regarding childhood fever, common infections, and self-management strategies for childcare staff and parents. The multicomponent intervention will be evaluated in a cluster randomised trial with a 12-week follow-up period and absenteeism due to illness (defined as the percentage of childcare days absent due to illness on the total of childcare days during a 12-week period as primary outcome measure. Secondary outcome measures are: incidence rate and duration of illness episodes, knowledge, attitude, self-efficacy, and risk perception on fever and common infections of childcare staff and parents, healthcare service use

  14. Nuclear cardiology procedures to diagnose ischemia in coronary artery disease

    International Nuclear Information System (INIS)

    Kropp, J.

    1999-01-01

    Nuclear cardiology is equipped with a broad spectrum of diagnostic capabilities which allow the evaluation of ventricular performance, perfusion and metabolism of the heart. The principle of nuclear medicine procedures consists in the administration of free radioisotopes or radiopharmaceuticals to detect their spatial distribution within the body by detecting their y-rays from outside by gamma cameras. Myocardial perfusion scintigraphy is the most important procedure in nuclear cardiology and is performed on a routine basis with 201 Thallium-Chloride ( 201 Tl) since 1975. With the Single-Photon Emission Computerized Tomography (SPECT) technique it is possible to diagnose ischemia of the left ventricle on the basis of coronary artery disease with a sensitivity of 90-95% and a specificity of about 55%. Recently 99m Tc-tracers were developed for this purpose, which have many advantages due to their better physical properties, their easy handling and availability. The diagnostic accuracy is the same compared to ( 201 Tl). Free fatty acids labeled with 123 Iodine like 123 IPPA are alternative tracers to diagnose ischemia by the metabolic alteration and are pathognomonic tracers to diagnose the heart involvement in myopathies or metabolic defects related to fatty acid degradation which are the main fuel of the normal myocytes. Finally we should not forget the radionuclide ventriculography (RNVG) which is one of the oldest nuclear cardiology procedures providing us with very objective, reliable results of ventricular performance.

  15. Enabling Precision Cardiology Through Multiscale Biology and Systems Medicine

    2017-06-01

    Full Text Available Summary: The traditional paradigm of cardiovascular disease research derives insight from large-scale, broadly inclusive clinical studies of well-characterized pathologies. These insights are then put into practice according to standardized clinical guidelines. However, stagnation in the development of new cardiovascular therapies and variability in therapeutic response implies that this paradigm is insufficient for reducing the cardiovascular disease burden. In this state-of-the-art review, we examine 3 interconnected ideas we put forth as key concepts for enabling a transition to precision cardiology: 1 precision characterization of cardiovascular disease with machine learning methods; 2 the application of network models of disease to embrace disease complexity; and 3 using insights from the previous 2 ideas to enable pharmacology and polypharmacology systems for more precise drug-to-patient matching and patient-disease stratification. We conclude by exploring the challenges of applying a precision approach to cardiology, which arise from a deficit of the required resources and infrastructure, and emerging evidence for the clinical effectiveness of this nascent approach.

    Early-career academic cardiologists, who many believe are an important component of the future of cardiovascular care, face myriad challenges. The Early Career Section Academic Working Group of the American College of Cardiology, with senior leadership support, assessed the progress of this cohort from 2013 to 2016 with a global perspective. Data consisted of accessing National Heart, Lung, and Blood Institute public information, data from the American Heart Association and international organizations, and a membership-wide survey. Although the National Heart, Lung, and Blood Institute increased funding of career development grants, only a small number of early-career American College of Cardiology members have benefited as funding of the entire cohort has decreased. Personal motivation, institutional support, and collaborators continued to be positive influential factors. Surprisingly, mentoring ceased to correlate positively with obtaining external grants. The totality of findings suggests that the status of early-career academic cardiologists remains challenging; therefore, the authors recommend a set of attainable solutions.

    As part of the American College of Cardiology Adult Congenital and Pediatric Cardiology Section effort to develop quality metrics (QMs) for ambulatory pediatric practice, the chest pain subcommittee aimed to develop QMs for evaluation of chest pain. A group of 8 pediatric cardiologists formulated candidate QMs in the areas of history, physical examination, and testing. Consensus candidate QMs were submitted to an expert panel for scoring by the RAND-UCLA modified Delphi process. Recommended QMs were then available for open comments from all members. These QMs are intended for use in patients 5-18 years old, referred for initial evaluation of chest pain in an ambulatory pediatric cardiology clinic, with no known history of pediatric or congenital heart disease. A total of 10 candidate QMs were submitted; 2 were rejected by the expert panel, and 5 were removed after the open comment period. The 3 approved QMs included: (1) documentation of family history of cardiomyopathy, early coronary artery disease or sudden death, (2) performance of electrocardiogram in all patients, and (3) performance of an echocardiogram to evaluate coronary arteries in patients with exertional chest pain. Despite practice variation and limited prospective data, 3 QMs were approved, with measurable data points which may be extracted from the medical record. However, further prospective studies are necessary to define practice guidelines and to develop appropriate use criteria in this population. © 2017 Wiley Periodicals, Inc.

    2012-07-01

    This essay analyses how the relationships between Cold War and post-Cold War politics, military psychiatry, humanitarian aid and mental health interventions in war and post-war contexts have transformed over time. It focuses on the restrictions imposed on humanitarian interventions and aid during the Cold War; the politics leading to the transfer of the PTSD diagnosis and its treatment from the military to civilian populations; humanitarian intervention campaigns in the post-Cold War era; and the development of psychosocial intervention programs and standards of care for civilian populations affected by armed conflict. Viewing these developments in their broader historical, political and social contexts reveals the politics behind mental health interventions conducted in countries and populations affected by warfare. In such militarized contexts, the work of NGOs providing assistance to people suffering from trauma-related health problems is far from neutral as it depends on the support of the military and plays an important role in the shaping of international politics and humanitarian aid programs.

    Early childhood intervention and habilitation services for children with disabilities operate on an interdisciplinary basis. It requires a common language between professionals, and a shared framework for intervention goals and intervention implementation. The International Classification of Functioning, Disability and Health (ICF) and the version for children and youth (ICF-CY) may serve as this common framework and language. This overview of studies implemented by our research group is based on three research questions: Do the ICF-CY conceptual model have a valid content and is it logically coherent when investigated empirically? Is the ICF-CY classification useful for documenting child characteristics in services? What difficulties and benefits are related to using ICF-CY model as a basis for intervention when it is implemented in services? A series of studies, undertaken by the CHILD researchers are analysed. The analysis is based on data sets from published studies or master theses. Results and conclusion show that the ICF-CY has a useful content and is logically coherent on model level. Professionals find it useful for documenting children's body functions and activities. Guidelines for separating activity and participation are needed. ICF-CY is a complex classification, implementing it in services is a long-term project.

    Sports cardiology is a new and rapidly evolving subspecialty. It aims to elucidate the cardiovascular effects of regular exercise and delineate its benefits and risks, so that safe guidance can be provided to all individuals engaging in sports and/or physical activity in order to attain the maximum potential benefit at the lowest possible risk. The European Society of Cardiology (ESC) advocates systematic preparticipation cardiovascular screening in an effort to identify competitive athletes at risk of exercise-related cardiovascular events and sudden cardiac death. However, the implementation of preparticipation screening is hindered because of lack of structured training and as a result lack of sufficient expertise in the field of sports cardiology. In 2008 the European Society of Cardiology published a core curriculum for the general cardiologist, in which sports cardiology was incorporated within the topic 'Rehabilitation and Exercise Physiology'. However, the exponential rise in knowledge and the growing demand for expertise in the field of sports cardiology dictates the need to systematically structure the knowledge base of sports cardiology into a detailed curriculum. We envisage that the curriculum would facilitate more uniform training and guideline implementation throughout Europe, and safeguard that evaluation and guidance of competitive athletes or individuals who wish to engage in leisure-time sports activities is performed by physicians with expertise in the field. The current manuscript provides a comprehensive curriculum for sports cardiology, which may serve as a framework upon which universities and national and international health authorities will develop the training, evaluation and accreditation in sports cardiology.

    The cardiologist is regularly consulted preoperatively by anaesthesiologists. However, insights into the efficiency and usefulness of these consultations are unclear. This is a retrospective study of 24,174 preoperatively screened patients ≥18 years scheduled for elective non-cardiac surgery, which resulted in 273 (1%) referrals to the cardiologist for further preoperative evaluation. Medical charts were reviewed for patient characteristics, main reason for referring, requested diagnostic tests, interventions, adjustment in medical therapy, 30-day mortality and major adverse cardiac events. The most common reason for consultation was the evaluation of a cardiac murmur (95 patients, 35%). In 167 (61%) patients, no change in therapy was initiated by the cardiologist. Six consultations (2%) led to invasive interventions (electrical cardioversion, percutaneous coronary intervention or coronary artery bypass surgery). On average, consultation delayed clearance for surgery by two weeks. In most patients referred to the cardiologist after being screened at an outpatient anaesthesiology clinic, echocardiography is performed for ruling out specific conditions and to be sure that no further improvement can be made in the patient's health. In the majority, no change in therapy was initiated by the cardiologist. A more careful consideration about the potential benefits of consulting must be made for every patient.

    Aim: to sensitize at the same time experts and public authorities on the interest of the establishment of nuclear cardiology in Senegal. Material and method: the radioimmunoassay of micro-albuminuria, early marker of cardiovascular morbid-mortality was carried out in the nuclear medicine department of Dakar on a population of 100 diabetic patients (74 of type 1 and 26 of type 2) presenting one or more traditional cardiovascular risk factors. Out of these patients, 39% had abnormal rest ECG, asymptomatic in half of the cases. Results: prevalence of micro-albuminuria is high (24%). There is no significant difference in distribution between type I and type 2. Micro-albuminuria > 30 mg/24 h exists in 16,3% of patients with lipid abnormalities (ratio: total cholesterol/HDL cholesterol > 5), 30% of obese, 75% of hypertensive patients and 43,6% of patients with abnormal rest ECG, who would benefit from myocardial perfusion imaging (MPI): about 17% of patients involved in this study. No or weak correlation is found between micro-albuminuria and traditional risk factors. Conclusion: From these results and available epidemiological data in 2005, the estimate of the requirements in nuclear cardiology for the Senegalese diabetic population, indicates that 3740 patients should have benefited that year from it. Considering that this figure underestimates the real needs, taking into account the needs brought back to a population of 10 million inhabitants and the expect expansion of the diabetic disease, it appears justified to include the nuclear cardiology in the national programmes of prevention of the public health in Senegal.

    Systematic assessments of the scientific production can optimize resource allocation and increase research productivity in Brazil. The aim of this study was to evaluate the profile and scientific production of researchers in the field of Cardiology who have fellowship in Medicine provided by the Conselho Nacional de Desenvolvimento Científico e Tecnológico. The curriculum Lattes of 33 researchers with active fellowships from 2006 to 2008 were included in the analysis. The variables of interest were: gender, affiliation, tutoring of undergraduate, masters and PhD students, and scientific production and its impact. : There was predominance of males (72.7%) and of fellowship level 2 (56.4%). Three states of the Federation were responsible for 94% of the researchers: SP (28; 71.8%), RS (4; 10.3%), e RJ (3; 9.1%). Four institutions are responsible for about 82% of researchers: USP (13; 39.4%), UNESP (5; 15.2%), UFRGS (4; 12.1%) e UNIFESP (3; 9.1%). During all academic careers, the researchers published 2.958 journal articles, with a mean of 89 articles per researcher. Of total, 55% and 75% were indexed at Web of Science and Scopus databases, respectively. The researchers received a total of 19648 citations at the database Web of Science, with a median of 330 citations per researcher (IQ = 198-706). The average number of citations per article was 13.5 citations (SD = 11.6). Our study has shown that researchers in the field of cardiology have a relevant scientific production. The knowledge of the profile of researchers in the field of Cardiology will probably enable effective strategies to qualitatively improve the scientific output of Brazilian researchers.

    Sudden cardiac death (SCD) is a common mode of death in hypertrophic cardiomyopathy (HCM), but identification of patients who are at a high risk of SCD is challenging as current risk stratification guidelines have never been formally validated. The objective of this study was to assess the power of the 2003 American College of Cardiology (ACC)/European Society of Cardiology (ESC) and 2011 ACC Foundation (ACCF)/American Heart Association (AHA) SCD risk stratification algorithms to distinguish high risk patients who might be eligible for an implantable cardioverter defibrillator (ICD) from low risk individuals. We studied 1606 consecutively evaluated HCM patients in an observational, retrospective cohort study. Five risk factors (RF) for SCD were assessed: non-sustained ventricular tachycardia, severe left ventricular hypertrophy, family history of SCD, unexplained syncope and abnormal blood pressure response to exercise. During a follow-up period of 11 712 patient years (median 6.6 years), SCD/appropriate ICD shock occurred in 20 (3%) of 660 patients without RF (annual rate 0.45%), 31 (4.8%) of 636 patients with 1 RF (annual rate 0.65%), 27 (10.8%) of 249 patients with 2 RF (annual rate 1.3%), 7 (13.7%) of 51 patients with 3 RF (annual rate 1.9%) and 4 (40%) of 10 patients with ≥4 RF (annual rate 5.0%). The risk of SCD increased with multiple RF (2 RF: HR 2.87, p≤0.001; 3 RF: HR 4.32, p=0.001; ≥4 RF: HR 11.37, p<0.0001), but not with a single RF (HR 1.43 p=0.21). The area under time-dependent receiver operating characteristic curves (representing the probability of correctly identifying a patient at risk of SCD on the basis of RF profile) was 0.63 at 1 year and 0.64 at 5 years for the 2003 ACC/ESC algorithm and 0.61 at 1 year and 0.63 at 5 years for the 2011 ACCF/AHA algorithm. The risk of SCD increases with the aggregation of RF. The 2003 ACC/ESC and 2011 ACCF/AHA guidelines distinguish high from low risk individuals with limited power.

    Epidemiologic transition is taking place in every part of the world. Cardiovascular diseases became the most common cause of death accounting for 30% of deaths worldwide, with 80% of the burden now occurring in developing countries. The objective of the study was to assess the Pattern of disease among patients attending Cardiology outpatient department of a private hospital. The cross sectional descriptive type of observational study was conducted among 550 patients attending Cardiology outpatient department (COPD) of Sodesh Hospital, Mymensingh, Bangladesh from March 2016 to June 2016. All the new patients attending COPD of Sodesh Hospital were selected purposively for the study. Data were collected by interview, physical examination and laboratory investigations of patients using a case record form. Mean age of the patients was 45.1 years with a SD of 15.6 years. Among the patients male were 291(52.9%), a bit higher than the female 259(47.1%). It was observed that more than half of the patients (281, 51.1%) visited cardiologist with non-cardiac problems. Less than one third of the patients (169, 30.7%) attended with cardiac problems and 100(18.2%) patients visited with both cardiac and non-cardiac problems. Among the cardiac diseases and symptoms hypertension was on the top of the list 176(65.4%). Ischemic heart diseases was present in 35(13.0%) and palpitation was in 30(11.1%) patients. On the other hand among the non-cardiac diseases or presentations, 121(43.1%) patients had non-specific chest pain, 63(22.4%) had shortness of breath and 17(6.1%) had diabetes mellitus. Hypertension was found the most frequent cardiovascular disease (65.4%) followed by ischemic heart disease (13.0%). More than half (51.1%) of the patients visit cardiologist with non-cardiac problems. Screening at the level of general practitioner (GP) and appropriate referral system can reduce extreme burden of patients to the cardiologists in the Cardiology outpatient department.

    Cardiovascular diseases (CVD) are the leading cause of mortality both in men and women. In Europe, about 55% of all females' deaths are caused by CVD, especially coronary heart disease and stroke. Unfortunately, however, the risk of heart disease in women is underestimated because of the perception that women are 'protected' against ischaemic heart disease. What is not fully understood is that women during the fertile age have a lower risk of cardiac events, but this protection fades after menopause thus leaving women with untreated risk factors vulnerable to develop myocardial infarction, heart failure, and sudden cardiac death. Furthermore, clinical manifestations of ischaemic heart disease in women may be different from those commonly observed in males and this factor may account for under-recognition of the disease. The European Society of Cardiology has recently initiated an extensive 'Women at heart' program to coordinate research and educational initiatives on CVD in women. A Policy Conference on CVD in Women was one of the first steps in the development of this program. The objective of the conference was to collect the opinion of experts in the field coming from the European Society of Cardiology member countries to: (1) summarize the state-of-the-art from an European perspective; (2) to identify the scientific gaps on CVD in women; and (3) to delineate the strategies for changing the misperception of CVD in women, improving risk stratification, diagnosis, and therapy from a gender perspective and increasing women representation in clinical trials. The Policy Conference has provided the opportunity to review and comment on the current status of knowledge on CVD in women and to prioritize the actions needed to advance this area of knowledge in cardiology. In the preparation of this document we intend to provide the medical community and the stakeholders of this field with an overview of the more critical aspects that have emerged during the discussion.

    In this article, we will provide a description of metabolomics in comparison with other, better known “omics” disciplines such as genomics and proteomics. In addition, we will review the current rationale for the implementation of metabolomics in cardiology, its basic methodology and the available data from human studies in this discipline. The topics covered will delineate the importance of being able to use the metabolomic information to understand the mechanisms of diseases from the perspective of systems biology, and as a non-invasive approach to the diagnosis, grading and treatment of cardiovascular diseases.

    Training of postgraduate students has traditionally been done in person in a hospital setting with hands-on training with each faculty member imparting knowledge to 2 to 4 students per year. Supplementing their practical education with online instruction could make a significant difference in standardizing pediatric cardiology education in India. To present the rationale, methods and survey results of a live e-Teaching methodology implemented for Pediatric cardiology trainees in association with the National Board of Examinations, India. Between March 2010 and March 2014, 310 e-classes were conducted in the Pediatric cardiac sciences by 24 e-teachers. Content of the e-Learning program was based on a 2-year pediatric cardiology curriculum and included twice-weekly live online video training sessions, a library of recorded sessions and online test quizzes for the students. A total of 231 students accessed the program at various times over the 4-year period. In our study, requests for access to the e-lectures increased from 10/year the first year to 100/year by the fourth year with feedback surveys conveying a high satisfaction level from the students and a high need for this knowledge. The advantages of virtual live e-Learning included the fact that one teacher can teach multiple students in multiple geographic locations at the same time, obviating the issue of quality teacher shortage and the same content can be disseminated to all students undergoing specialist training so there is a national consensus on diagnostic and management approach among all trainees. Additionally, the e-classes can be recorded and replayed so they can be viewed repeatedly by the same group or new trainees. This is the first sustained use of e-Teaching in a medical super-specialty in India. We believe that e-Teaching is an innovative solution that can be applied, not just to Pediatric Cardiology as we have done, but to all branches of specialist and super-specialist medical training in

    Expert knowledge of cardiac malformations is essential for paediatric cardiologists. Current cardiac morphology fellowship teaching format, content, and nomenclature are left up to the discretion of the individual fellowship programmes. We aimed to assess practices and barriers in morphology education, perceived effectiveness of current curricula, and preferences for a standardised fellow morphology curriculum. A web-based survey was developed de novo and administered anonymously via e-mail to all paediatric cardiology fellowship programme directors and associate directors in the United States of America; leaders were asked to forward the survey to fellows. A total of 35 directors from 32 programmes (51%) and 66 fellows responded. Curriculum formats varied: 28 (88%) programmes utilised pathological specimens, 25 (78%) invited outside faculty, and 16 (50%) utilised external conferences. Director nomenclature preferences were split - 6 (19%) Andersonian, 8 (25%) Van Praaghian, and 18 (56%) mixed. Barriers to morphology education included time and inconsistent nomenclature. One-third of directors reported that <90% of recent fellow graduates had adequate abilities to apply segmental anatomy, identify associated cardiac lesions, or communicate complex CHD. More structured teaching, protected time, and specimens were suggestions to improve curricula. Almost 75% would likely adopt/utilise an online morphology curriculum. Cardiac morphology training varies in content and format among fellowships. Inconsistent nomenclature exists, and inadequate morphology knowledge is perceived to contribute to communication failures, both have potential patient safety implications. There is an educational need for a common, online cardiac morphology curriculum that could allow for fellow assessment of competency and contribute to more standardised communication in the field of paediatric cardiology.

    The Fellowship Program of the Department of Cardiology at Boston Children's Hospital seeks to train academically oriented leaders in clinical care and laboratory and clinical investigation of cardiovascular disease in the young. The core clinical fellowship involves 3 years in training, comprising 24 months of clinical rotations and 12 months of elective and research experience. Trainees have access to a vast array of research opportunities - clinical, basic, and translational. Clinical fellows interested in basic science may reverse the usual sequence and start their training in the laboratory, deferring clinical training for 1 or more years. An increasing number of clinical trainees apply to spend a fourth year as a senior fellow in one of the subspecialty areas of paediatric cardiology. From the founding of the Department to the present, we have maintained a fundamental and unwavering commitment to training and education in clinical care and research in basic science and clinical investigation, as well as to the training of outstanding young clinicians and investigators.

    This work is based on a acquisition and pretreating Service of data and signals resulting from several types of functional explorations in cardiology. This Service, through a specialised phone-line, is connected to the Medical Centre of Informatic where the different treatments and on occasion the recording of data are carried out. This functions according to the Real Time Executive System and the clinical results are send back to the investigation unit. The main types of cardiologic analysis as studied by the system are envisaged: measure in real time of the cardiac output and analysis of the radiocardiogram, measure and display of the thoracic potentials, spectral analysis of the vectorcardiogram, quantitative cineangiocardiography and analysis of intracardiac pressures. This system is particularly interesting in that it may treat several processes which could ask for a great capacity of storing and an important calculus power, see for instance the study of thoracic potentials. This type of analysis could not be envisaged financially with isolated calculators. The set of results obtained enables us to investigate thoroughly and precisely the cardiac performance [fr

    Full Text Available Carlos S de la Calzada Department of Medicine, Universidad Complutense de Madrid, Madrid, SpainAbstract: It is well known that an expert clinician formulates a diagnostic hypothesis with little clinical data. In comparison, students have difficulties in doing so. The mental mechanism of diagnostic reasoning is almost unconscious and therefore difficult to teach. The purpose of this essay (devoted to 2nd-year medical students is to present an integrating framework to teach clinical reasoning in cardiology. By analyzing cardiology with a synthetic mind, it becomes apparent that although there are many diseases, the heart, as an organ, reacts to illness with only six basic responses. The clinical manifestations of heart diseases are the direct consequence of these cardiac responses. Considering the six cardiac responses framework, diagnostic reasoning is done in three overlapping steps. With the presented framework, the process of reasoning becomes more visual and needs less clinical data, resembling that of the expert clinician.Keywords: clinical deduction, diagnostic reasoning, education, teaching methods

    The future of nuclear medicine procedures, as understood within our current economic climate, depends upon its ability to provide relevant clinical information at similar or lower comparative costs. With an ever-increasing emphasis on cost containment, outcome assessment forms the basis of preserving the quality of patient care. Today, outcomes assessment encompasses a wide array of subjects including clinical, economic, and humanistic (i.e., quality of life) outcomes. For nuclear cardiology, evidence-based medicine would require a threshold level of evidence in order to justify the added cost of any test in a patient's work-up. This evidence would include large multicenter, observational series as well as randomized trial data in sufficiently large and diverse patient populations. The new movement in evidence-based medicine is also being applied to the introduction of new technologies, in particular when comparative modalities exist. In the past 5 years, it has seen a dramatic shift in the quality of outcomes data published in nuclear cardiology. This includes the use of statistically rigorous risk-adjusted techniques as well as large populations (i.e., >500 patients) representing multiple diverse medical care settings. This has been the direct result of the development of multiple outcomes databases that have now amassed thousands of patients worth of data. One of the benefits of examining outcomes in large patient datasets is the ability to assess individual endpoints (e.g., cardiac death) as compared with smaller datasets that often assess combined endpoints (e.g., death, myocardial infarction, or unstable angina). New technologies for the diagnosis of coronary artery disease have contributed to the rising costs of care. In the United States and in Europe, costs of care have risen dramatically, consuming an ever-increasing amount of available resources. The overuse of diagnostic angiography often leads to unnecessary revascularization that does not lead to

    In an attempt to deal with the pressures on the healthcare system and to guarantee sustainability, changes are needed. This study is focused on a cardiology Primary Care Plus intervention in which cardiologists provide consultations with patients in a primary care setting in order to prevent unnecessary referrals to the hospital. This study explores which patients with non-acute and low-complexity cardiology-related health complaints should be excluded from Primary Care Plus and referred directly to specialist care in the hospital. This is a retrospective observational study based on quantitative data. Data collected between January 1 and December 31, 2015 were extracted from the electronic medical record system. Logistic regression analyses were used to select patient groups that should be excluded from referral to Primary Care Plus. In total, 1525 patients were included in the analyses. Results showed that male patients, older patients, those with the referral indication 'Stable Angina Pectoris' or 'Dyspnoea' and patients whose reason for referral was 'To confirm disease' or 'Screening of unclear pathology' had a significantly higher probability of being referred to hospital care after Primary Care Plus. To achieve efficiency one should exclude patient groups with a significantly higher probability of being referred to hospital care after Primary Care Plus.

    We are in the midst of a digital revolution in health care, although the application of new and useful technology in routine clinical practice is variable. The Characterizing Atrial fibrillation by Translating its Causes into Health Modifiers in the Elderly (CATCH ME) Consortium, in collaboration with the European Society of Cardiology (ESC), has funded the creation of two applications (apps) in atrial fibrillation (AF) for use in smartphones and tablets. The patient app aims to enhance patient education, improve communication between patients and health care professionals, and encourage active patient involvement in the management of their condition. The health care professional app is designed as an interactive management tool incorporating the new ESC Practice Guidelines on AF and supported by the European Heart Rhythm Association (EHRA), with the aim of improving best practice approaches for the care of patients with AF. Both stand-alone apps are now freely available for Android and iOS devices though the Google Play, Amazon, and Apple stores. In this article, we outline the rationale for the design and implementation of these apps. Our objective is to demonstrate the value of integrating novel digital technology into clinical practice, with the potential for patient engagement, optimization of pharmacological and interventional therapy in AF, and ultimately to improve patient outcomes. © The Author 2017.

    Full Text Available This article examines the practice of doctors and nurses to invoke the categories of age, sex, class, ethnicity, and/or lifestyle factors when discussing individual patients and patient groups. In what situations are such references explicitly made, and what does this practice accomplish? The material consists of field notes from a cardiology clinic in Sweden, and a theory of descriptive practice guided the analysis. When professionals describe patients, discuss decisions, or explain why a patient is ill, age, sex, class, ethnicity, and/or lifestyle serve as contextualization cues, often including widespread results from epidemiological research about groups of patients at higher or lower risk for cardiac disease. These categories work as shortcut reasoning to nudge interpretations in a certain direction, legitimize decisions, and strengthen arguments. In general, studying the descriptions of patients/clients/students provides an entrance to professional methods of reasoning, including their implicit moral assumptions.

    This article presents the development of a Cardiology Electronic Health Record (CEHR) system. Software consists of a structured algorithm designed under Health Level-7 (HL7) international standards. Novelty of the system is the integration of high resolution ECG (HRECG) signal acquisition and processing tools, patient information management tools and telecardiology tools. Acquisition tools are for management and control of the DIGICARDIAC electrocardiograph functions. Processing tools allow management of HRECG signal analysis searching for indicative patterns of cardiovascular pathologies. Telecardiology tools incorporation allows system communication with other health care centers decreasing access time to the patient information. CEHR system was completely developed using open source software. Preliminary results of process validation showed the system efficiency.

    Women are less present on the labor market and many studies have demonstrated the existence of gender differences regarding participation rate and career advancement of women. The process through which job-, career- and research-related choices are structured within the realm of Italian cardiology, is described in this study emphasizing the effects of productivity, gender and family commitments. In June 1996, a questionnaire was mailed to all members of the Italian societies of cardiology. It included mainly (pre-coded) set-choice questions concerning individual characteristics, career-related data, and information pertaining to teaching, scientific and research activity. Returned questionnaires numbered 1715 (21.4% of the total mailed), 83% were completed by males and 17% by females. For both hospital and academic careers, advancement in rank was influenced by variables denoting productivity, family and individual characteristics. Promotion to the upper ranks of the hierarchy was highly dependent upon time (once the effects of the covariates were eliminated). This is a situation that is typical of the internal labor market, that is, of an institution in which staff members are ranked on a hierarchical scale according to formal criteria that are "rigid" and institutionalized, partially and totally sheltered from competition. Therefore, once a member has gained access to the first level of the hierarchy, his/her professional career is to a certain extent pre-determined and the seniority ends up taking on importance in promotion decisions to an appreciable extent; in this field, the weight of seniority on promotion ranges between 30 and 50%.

    Towards the middle of the XVI century, the empirical physician Martín de la Cruz, in New Spain, compiled a catalogue of the local medicinal herbs and plants, which was translated into Latin by Juan Badiano, professor at the Franciscan college of Tlatelolco. On his side, Dr. Francisco Hernández, the royal physician (protomédico) from 1571 until 1577, performed a systematic study of the flora and fauna in this period. His notes and designs were not published at that time, but two epitomes of Hernández' works appeared, respectively, in 1615 in Mexico and in 1651 in Rome. During the XVIII century, two Spanish scientific expeditions arrived to these lands. They were led, respectively, by the Spanish naturalist Martín Sessé and the Italian seaman, Alessandro Malaspina di Mulazzo, dependent from the Spanish Government. These expeditions collected and carried rich scientific material to Spain. At the end of that century, the Franciscan friar Juan Navarro depicted and described several Mexican medicinal plants in the fifth volume of his botanic work. In the last years of the colonial period, the fundamental works of Humboldt and Bonpland on the geographic distribution of the American plants were published. In the modern age, the first research about the Mexican medicinal botany was performed in the laboratory of the Instituto Médico Nacional [National Medical Institute] under the leadership of Dr. Fernando Altamirano, who started pharmacological studies in this country. Later, trials of cardiovascular pharmacology were performed in the small laboratories of the cardiological unit at the General Hospital of Mexico City, on Dr. Ignacio Chávez' initiative. The Mexican botanical-pharmacological tradition persists alive and vigorous at the Instituto Nacional de Cardiología and other scientific institutions of the country.

    High-fidelity patient simulation (HFPS) has been used in medical education to bridge gaps in medical knowledge and clinical skills. Few studies have analyzed the impact of HFPS in subspecialty rotations for pediatric residents. We hypothesized that pediatric residents exposed to HFPS with a structured content curriculum would perform better on a case quiz than residents without exposure to HFPS. Prospective randomized controlled Tertiary-care free standing children's hospital During a cardiology rotation, senior pediatric residents completed an online pediatric cardiology curriculum and a cardiology quiz. After randomization into two groups, the study group participated in a fully debriefed HFPS session. The control group had no HFPS. Both groups completed a case quiz. Confidence surveys pre- and postsimulation were completed. From October 2010 through March 2013, 55 residents who rotated through the pediatric cardiology rotation were used in the final analysis (30 control, 25 in the study group). There was no significant difference between groups on the initial cardiology quiz. The study group scored higher on the case quiz compared with the control group (P = .024). Based on pre- and postsimulation questionnaires, residents' confidence in approaching a pediatric cardiology patient improved from an average Likert score of 5.1 to 7.5 (on scale of 0-10) (P cardiology rotation was feasible and well received. Our study suggests that simulation promotes increased confidence and may modestly improve clinical reasoning compared to traditional educational techniques. Targeted simulation sessions may readily be incorporated into pediatric subspecialty rotations. © 2014 Wiley Periodicals, Inc.

    International guidelines advocate depression screening in patients with coronary heart disease (CHD) and other chronic illnesses, but evidence is lacking. To test the differential efficacy of written patient-targeted feedback v. no written patient feedback after depression screening. Patients with CHD or hypertension from three cardiology settings were randomised and screened for depression (ClinicalTrials.gov Identifier: NCT01879111). Compared with the control group, where only cardiologists received written feedback, in the intervention group both cardiologists and patients received written feedback regarding depression status. Depression severity was measured 1 month (primary outcome) and 6 months after screening. The control group (n = 220) and the patient-feedback group (n = 155) did not differ in depression severity 1 month after screening. Six months after screening, the patient-feedback group showed significantly greater improvements in depression severity and was twice as likely to seek information about depression compared with the control group. Patient-targeted feedback in addition to screening has a significant but small effect on depression severity after 6 months and may encourage patients to take an active role in the self-management of depression. © The Royal College of Psychiatrists 2017.

  14. Top of the charts: download versus citations in the International Journal of Cardiology.

    The medical literature is growing at an alarming rate. Research assessment exercises, research quality frameworks, league tables and the like have attempted to quantify the volume, quality and impact of research. Yet the established measures (such as citation rates) are being challenged by the sheer number of journals, variability in the "gold standard" of peer-review and the emergence of open-source or web-based journals. In the last few years, we have seen a growth in downloads to individual journal articles that now easily exceeds formal journal subscriptions. We have recorded the 10 top cited articles over a 12-month period and compared them to the 10 most popular articles being downloaded over the same time period. The citation-based listing included basic and applied, observational and interventional original research reports. For downloaded articles, which have shown a dramatic increase for the International Journal of Cardiology from 48,000 in 2002 to 120,000 in 2003 to 200,000 in 2004, the most popular articles over the same period are very different and are dominated by up-to-date reviews of either cutting-edge topics (such as the potential of stem cells) or of the management of rare or unusual conditions. There is no overlap between the two lists despite covering exactly the same 12-month period and using measures of peer esteem. Perhaps the time has come to look at the usage of articles rather than, or in addition to, their referencing.

    Medical discharge management of acute coronary syndromes (ACS) remains suboptimal outside randomised trials and constitutes an essential quality benchmark for ACS. We sought to evaluate the rates of key guideline-recommended pharmacological agents after ACS and characteristics associated with optimal treatment at discharge. The Rijnmond Collective Cardiology Research (CCR) registry is an ongoing prospective, observational study in the Netherlands that aims to enrol 4000 patients with ACS. We examined discharge and 1-month follow-up medication use among the first 1000 patients enrolled in the CCR registry. Logistic regression was performed to identify patient and hospital characteristics associated with collective guideline-recommended pharmacotherapy at hospital discharge. At discharge, 94 % of patients received aspirin, 100 % thienopyridines, 80 % angiotensin-converting enzyme inhibitors/angiotensin-II receptor blockers, 87 % β-blockers, 96 % statins, and 65 % the combination of all 5 agents. ST-segment elevation myocardial infarction, hypertension, hypercholesterolaemia, and enrolment in an interventional centre were positive independent predictors of 5-drug combination therapy at discharge. Negative independent predictors were unstable angina and advanced age. Current data from the CCR registry reflect a high quality of care for ACS discharge management in the Rotterdam-Rijnmond region. However, potential still remains for further optimisation.

    A prospective cohort study with identical questionnaires and inclusion criteria was performed. To compare in six different countries the frequencies and effects of the common medical interventions used for patients with low back pain who are work incapacitated. Low back pain is a huge problem with increasing costs for health care, industry, and society. Cohorts of employed men and women ages 18 to 59 years who had been sick-listed (100%) for a minimum of 90 days because of low back pain were recruited in Denmark, Germany, Israel, Sweden, the Netherlands, and the United States. The subjects received three separate questionnaires with identical questions after 90 days, 1 year, and 2 years. The questionnaires included separate questions about background factors, treatment, and the like, as well as validated scales such as the Hannover Activities of Daily Living, von Korff pain score, Short Form-36, and Karasek-Theorell. Working status was obtained from registers. Main outcome measures were working/not working, back function, and pain. All three questionnaires were completed by 2080 subjects in the six countries. With few exceptions, there were great similarities in the appointments, examinations, and treatments in the different countries. Considerable differences were found between the back surgery rates, which ranged from 6% in Sweden to 32% in the United States during the first 90 days of the study. Very few of the interventions had any noticeable positive effects on work resumption, pain, or back function. Back surgery in Sweden was a striking exception, positively affecting all three outcome measures. The frequencies of work resumption within the first year ranged from 73% in the Netherlands to 32% in Denmark. Almost none of the commonly occurring and frequently practiced medical interventions for patients who are sick-listed because of low back pain had any positive effects on either the recorded health measures or work resumption.

    To validate the modified World Health Organization (mWHO) risk classification in advanced and emerging countries, and to identify additional risk factors for cardiac events during pregnancy. The ongoing prospective worldwide Registry Of Pregnancy And Cardiac disease (ROPAC) included 2742 pregnant women (mean age ± standard deviation, 29.2 ± 5.5 years) with established cardiac disease: 1827 from advanced countries and 915 from emerging countries. In patients from advanced countries, congenital heart disease was the most prevalent diagnosis (70%) while in emerging countries valvular heart disease was more common (55%). A cardiac event occurred in 566 patients (20.6%) during pregnancy: 234 (12.8%) in advanced countries and 332 (36.3%) in emerging countries. The mWHO classification had a moderate performance to discriminate between women with and without cardiac events (c-statistic 0.711 and 95% confidence interval (CI) 0.686-0.735). However, its performance in advanced countries (0.726) was better than in emerging countries (0.633). The best performance was found in patients with acquired heart disease from developed countries (0.712). Pre-pregnancy signs of heart failure and, in advanced countries, atrial fibrillation and no previous cardiac intervention added prognostic value to the mWHO classification, with a c-statistic of 0.751 (95% CI 0.715-0.786) in advanced countries and of 0.724 (95% CI 0.691-0.758) in emerging countries. The mWHO risk classification is a useful tool for predicting cardiac events during pregnancy in women with established cardiac disease in advanced countries, but seems less effective in emerging countries. Data on pre-pregnancy cardiac condition including signs of heart failure and atrial fibrillation, may help to improve preconception counselling in advanced and emerging countries. © 2016 The Authors.

    Mortality and rehospitalizations still remain high after discharge for an acute cardiologic event. In this context, hospital discharge represents a potential pitfall for heart disease patients. In the setting of care transitions, the discharge letter is the main instrument of communication between hospital and primary care. Communication, besides, is an integral part of high-quality, patient-centered interventions aimed at improving the discharge process. Inadequate information at discharge significantly affects the quality of treatment compliance and the adoption of lifestyle modifications for an effective secondary prevention. The Health Department of Sicily, in 2013, established a task force with the aim to elaborate "Regional recommendations for hospital discharge and communication with patients after admission due to a cardiologic event", inviting to participate GICR-IACPR and many other scientific societies of cardiology and primary care, as discharge letter and communication are fundamental junctions of care transitions in cardiology. These recommendations have been published as a specific decree and contain: a structured model of discharge letter, which includes all of the parameters characterizing patients at high clinical risk, high thrombotic risk and low risk according to the Consensus document ANMCO/GICR-IACPR/GISE; is thus possible to identify these patients, choosing consequently the most appropriate follow-up pathways. A particular attention has been given to the "Medication Reconciliation" and to the identification of therapeutic targets; an educational Kit, with different forms on cardiac diseases, risk factors, drugs and lifestyle; a check-list about information given to the patient and caregivers. The "Recommendations" represent, in conclusion, the practical realization of the fruitful cooperation between scientific societies and political-administrative institutions that has been realized in Sicily in the last years.

    To review the number, characteristics and clinical management of suspected ACS patients admitted to cardiology and non-cardiology services at Auckland City Hospital, to assess differences between these services and to assess the number who would potentially be enrolled in the All New Zealand Acute Coronary Syndrome (ACS) Quality Improvement Programme (ANZACS-QI) database. Auckland City Hospital patient data was extracted from the Australia and New Zealand ACS 'SNAPSHOT' audit, performed over 14 days in May 2012. There were 121 suspected ACS admissions to Auckland City hospital during the audit period, with 45 (37%) patients directly managed by the cardiology service, and 76 (63%) patients cared for by non-cardiology services. Based on the subsequent discharge diagnosis, the cardiology service had more patients with definite ACS than the non-cardiology services; 27/45 (60%) compared to 16/76 (21%), difference (95%CI) 39% (22-56), P<0.0001). Cardiology ACS patients were more likely to undergo echocardiography; 15/27 (56%) compared to 2/16 (13%), difference 42% (18-68), P=0.0089), coronary angiography; 21/27 (78%) compared to 3/16 (19%), difference (95%CI) 59% (34-84), P=0.0003), coronary revascularisation; 18/27 (67%) compared to 3/16 (19%), difference (95%CI) 48% (22-74), P=0.004, and be discharged on two antiplatelet agents; 18/26 (69%) compared to 3/15 (20%), difference (95%CI) 49% (22-76), P=0.0036, or an ACEI/ARB; 20/26 (77%) compared to 5/15 (33%), difference (95%CI) 44% (15-72), P=0.0088. In patients with a discharge diagnosis of definite ACS, those managed by non-cardiology services were less likely to receive guideline-recommended investigations, and management, in this relatively small cohort study. About one-third of all ACS patients are managed by non-cardiology services and would not be recorded by the ANZACS-QI database.

    OBJECTIVES The aim of this study was to investigate gender-based differences in nuclear cardiology practice, globally, with particular focus on laboratory volume, radiation dose, protocols, and best practices. BACKGROUND It is unclear if gender-based differences exist in radiation exposure for nuclear cardiology procedures. METHODS In a large multicenter observational cross-sectional study encompassing 7911 patients in 65 countries, radiation effective dose was estimated for each examination. Patient-level best practices relating to radiation exposure were compared between genders. Analysis of covariance was utilized to determine any difference in radiation exposure according to gender, region, and the interaction between gender and region. Linear, logistic, and hierarchical regression models were developed to evaluate gender-based differences in radiation exposure and laboratory adherence to best practices. We also included the United Nations’ gender inequality and human development indices as covariates in multivariable models. RESULTS The proportion of MPI studies performed in women varied between countries, however there was no significant correlation with gender inequality index. Globally, mean effective dose for nuclear cardiology procedures was only slightly lower in women (9.6±4.5 mSv) than in men (10.3±4.5 mSv men, pnuclear cardiology procedures, only small differences were observed between genders worldwide. Regional variations noted in MPI use and radiation dose offer potential opportunities to address gender-related differences in delivery of nuclear cardiology care. PMID:27056156

    Electrocardiographic (ECG) pre-participation screening can prevent sudden cardiac death in the athletes by early diagnosis and disqualification of affected individuals. Interpretation of the athlete's ECG should be based on specific criteria, because ECG changes that would be considered abnormal in the untrained population may develop in trained athletes as a physiologic and benign consequence of the heart's adaptation to exercise. In 2010, a stem document from the Section of Sports Cardiology of the European Society of Cardiology (ESC) proposed to classify the athlete's ECG changes according to the prevalence, relation to exercise training, association with an increased risk of cardiovascular disease and need for further investigations into two groups: "common and training-related" (Group 1) and "uncommon and training-unrelated" (Group 2). Over the last years, several efforts have been made to refine the ESC criteria for interpretation of the athlete's ECG in order to improve specificity maintaining good sensitivity, especially among elite and Afro-Caribbean athletes, which show the highest rate of false positives Group 2 ECG abnormalities. However, the balance between improvement in specificity and loss of sensitivity should be evaluated keeping in mind that the primary aim of the screening program is to save the athlete's lives rather than money.

    The provision of an efficient consultation service is essential to the efficient functioning of any hospital. Surprisingly little is known about this activity. We present the first reported evaluation of a cardiology consultation service in an attempt to determine the characteristics, efficiency and workload implications of such a service. We performed an audit of the in-patient cardiology consultation service over a four week period. During this period, 125 consultations were seen, of which 85 (68%) were requested by medical specialties. Consultations were seen in a timely fashion, with 76 (61%) being seen on the same day that the request was received. The most common problem was chest pain, (49 patients; 38%) which was felt to be of cardiac origin in only a minority (20; 40%) of cases. Consultations had significant resource implications for our department, with 35 (28%) procedures being performed, 25 (20%) patients\\' care being taken over, and a further 27 (21.6%) new out-patient referrals generated. Our results indicate that the consultation service considered was efficiently delivered but contributed significantly to the department\\'s workload. The most frequent consultation request was for chest pain that was often non-cardiac in nature.

    Tree-structured methodology applied for the GISSI-PSICOLOGIA project, although performed in the framework of earliest GISSI studies, represents a powerful tool to analyze different aspects of cardiologic care. The GISSI-PSICOLOGIA project has delivered a novel methodology based on the joint application of psychometric tools and sophisticated statistical techniques. Its prospective use could allow building effective epidemiological models relevant to the prognosis of the cardiologic patient. The various features of the RECPAM method allow a versatile use in the framework of modern e-health projects. The study used the Cognitive Behavioral Assessment H Form (CBA-H) psychometrics scales. The potential for its future application in the framework of Italian cardiology is relevant and particularly indicated to assist planning of systems for integrated care and routine evaluation of the cardiologic patient.

    In medical care settings, mental health symptoms of depression and distress are associated with poor medical outcomes, yet they are often underrecognized. Authors sought to examine the effect of having immediate mental-health screening in the cardiology clinic. The Patient Health Questionnaire and the Impact of Event Scale were used to screen for depression and distress in 316 patients at an urban cardiology clinic. Because of poor follow-up rates, a psychiatrist was placed on the premises of the cardiology clinic to facilitate referrals. Placing a psychiatrist within the cardiology clinic significantly improved the rate of successful referrals. Because 45 patients (14%) endorsed suicidal thoughts, authors conclude that mental health screening programs should include an immediate evaluation by a clinician.

    Magnetic resonance (MR) is considered the gold standard in the assessment of myocardial morphology, function, perfusion, and viability. However, its main limitation is its scarce availability. In 2014, we installed the first MR scanner exclusively managed by a cardiology department within the publicly-funded Spanish healthcare system with the aim of improving patient-care, training and research in the department. In the time interval analyzed, July 2014 to May 2017, 3422 cardiac MR scans were performed (32minutes used per study; 96% with good quality; 75% with contrast media administration). The most prevalent clinical indications were cardiomyopathy (29%) and ischemic heart disease (12%). Twenty-five percent of studies were conducted in the context of research protocols. Follow-up studies predominated among outpatients, while pretherapeutic assessment was more common in hospitalized patients. The presumptive diagnosis was changed by cardiac MR scanning in up to 20% of patients investigated for ischemic heart disease. The installation and operative management of an MR scanner in our cardiology department has allowed us to integrate this technique into daily clinical practice, modify our clinical protocols, optimize access to this technology among cardiac patients, improve training, and conduct clinical research.

    Full Text Available To evaluate the degree of compliance with pharmacological therapy, and to identify predictors of non-compliance in outpatients from a cardiology referral center in São Paulo, Brazil, we studied 485 outpatients, 230 (47.4 percent males and 255 (52.6 percent females, through an interview guided by a questionnaire during medical consultation. The ages ranged between 17 and 86 (mean 54, standard deviation 15 years. Heart disease and socioeconomic factors (residence, means of transport, educational level and professional status were studied. In addition, we examined the drugs prescribed including: difficulties in taking them; the source of supply; and the patient's knowledge of the drugs. Assessment of compliance was based on the patients' response. The patients' answers were compared with the prescription and progress notes. Errors were recorded if the patient reported using one or more nonprescribed medicines. Compliance with therapy was recorded if the patient said the prescription was taken correctly without interruption and without error. The variables with significant differences in univariate analysis were further analyzed by multivariate log-linear regression analysis. Noncompliance occurred in 286 (59 percent of the patients, and was predicted by the reported difficulty in taking medication (P<0.001, and by the lack of knowledge of medication names (P<0.001.Thus, noncompliance with medical therapy was common. The main predictors of non-compliance were the reported difficulty in taking medication and inability to identify medicines' names.

    Many advances have been made in the field of nuclear cardiology in the past decade for enhancing the diagnostic and prognostic value of stress myocardial variability using SPECT technology. Gated SPECT for determining regional and global function have provided incremental diagnostic and prognostic information in the evaluation of patients with suspected or known coronary artery disease. Left ventricular ejection fraction and regional myocardial wall thickening can now be simultaneously evaluated with regional perfusion particularly with the use of the 99m Tc-labeled perfusion agents such as sestamibi and tetrofosmin. Many studies have shown that the extent and severity of stress-induced perfusion defects have incremental prognostic value over exercise electrocardiographic stress test variables alone. Patients with normal perfusions scans have 201 Tl or with one of the 99m Tc-labeled imaging agents, or PET imaging with 18 F-deoxyglucose can accurately distinguish viable from irreversibility injured myocardium providing useful information for identifying which patients with ischemic cardiomyopathy benefit most from coronary revascularization with a subsequent improvement in left ventricular function and enhanced survival. Finally, serial stress perfusion imaging can be employed to monitor the efficacy of medical therapy that improves endothelial function and myocardial blood flow reserve

    Modern medical science was born in the post-Renaissance age and began to consolidate towards the middle of the XVII century thanks to physicists, physiologists and biologists, most of whom were direct or indirect pupils of Galileo. The discovery of blood circulation by Harvey is now considered the only progress in physiology at the beginning of the XVII century, comparable to the current advances seen in physical sciences. The history of this exploit could be written from view point of the progressive advance in knowledge. In his experiments, Harvey referred to the authentic not imaginary experiments, and put forward irrefutable quantitative arguments. We can therefore claim that his discovery of blood circulation was the first proper explanation of an organic process and the starting point leading to experimental physiology. So it seems justified to assert that modern medical science did not all rise suddenly, but was gradually structured starting from the middle of the XVII century following the path traced by William Harvey in light of Galileo's thought.

    The last years, new radiopharmaceuticals are used in a Nuclear Medicine (NM) Department. Nowadays, Single Photon Emission Computed Tomography (SPECT) is a method of routine imaging, a fact that has required increased levels of radioactivity in certain patient examinations. The staff that is more likely to receive the greatest radiation dose in a NM Department is the technologist who deals with performance of patient examination and injection of radioactive material and the nurse who is caring for the patients visiting the Department some of which being totally helpless. The fact that each NM Dept possesses equipment with certain specifications, deals with various kind of patients, has specific design and radiation protection measures which can differ from other NM Depts and uses various examination protocols, makes essential the need to investigate the radiation doses received by each member of the staff, so as to continuously monitor doses and take protective measures if required, control less experienced staff and ensure that radiation dose levels are kept as low as possible at all times. The purpose of the current study was to evaluate radiation dose to the nuclear cardiology department staff by thermoluminescent dosemeters (TLDs) placed on the the skin at thyroid and abdominal region as well as evaluating protection measures taken currently in the Dept

    As in other fields, understanding of vascular risk and rehabilitation is constantly improving. The present review of recent epidemiological update shows how far we are from achieving good risk factor control: in diet and nutrition, where unhealthy and excessive societal consumption is clearly increasing the prevalence of obesity; in exercise, where it is difficult to find a balance between benefit and risk, despite systemization efforts; in smoking, where developments center on programs and policies, with the electronic cigarette seeming more like a problem than a solution; in lipids, where the transatlantic debate between guidelines is becoming a paradigm of the divergence of views in this extensively studied area; in hypertension, where a nonpharmacological alternative (renal denervation) has been undermined by the SYMPLICITY HTN-3 setback, forcing a deep reassessment; in diabetes mellitus, where the new dipeptidyl peptidase-4 and sodium-glucose cotransporter type 2 inhibitors and glucagon like peptide 1 analogues have contributed much new information and a glimpse of the future of diabetes treatment, and in cardiac rehabilitation, which continues to benefit from new information and communication technologies and where clinical benefit is not hindered by advanced diseases, such as heart failure. Our summary concludes with the update in elderly patients, whose treatment criteria are extrapolated from those of younger patients, with the present review clearly indicating that should not be the case.

    At present the most widely used element in isotopic cardiology is undoubtedly 201 Tl. In the few years since its appearance many publication testify to its growing use in the external detection of coronary thrombosis, the discovery of ischemia exertion, the non-traumatic observation of patients after an aortocoronary bridging operation, the diagnosis of coronary deficiency associated with another heart disease (aorta narrowing, mitral prolapsus, obstructive cardiomyopathy) and in combination with two other radioisotopic methods. The present work is intended as a modest contribution, still very recent, to the critical study of this new technique in all its present aspects. Part one presents the various characteristics responsible for the advantages and limits of 201 Tl, then describes the techniques and apparatus used. The production, dosimetry, toxicity and biological behaviour of 201 Tl are also discussed. A hundred and twenty-five examinations were performed in the Nuclear Medicine Service of the Limoges UHC between May 1977 and October 1978. The results are analysed in part two. This is followed by a discussion which attempts, in the light of our experience, to situate the place occupied by 201 Tl in the range of complementary examinations useful in declared or assumed coronary cases. We then propose an examination procedure and precise indications we believe to be justified, accounting for economic problems before considering the future prospects of myocardium scintigraphy [fr

    Further actions to improve radiation safety in this medical practice are discussed. All the X-ray systems used in paediatric IC procedures in Chile have been characterized in terms of dose and image quality. In addition, dose rates of scattered radiation to the position of the eyes and ankles of cardiologists have been measured. In May 2010, in Santiago, Chile, a workshop organized by the International Atomic Energy Agency (IAEA) was the starting point for a pilot program on patient dosimetry and medical personnel for Latin America and the Caribbean, with participants from 11 countries. A pilot training course on Radiological Protection was given as part of the program. The first dose values reported for paediatric patients under the pilot program conducted by the IAEA in Latin America and the Caribbean included 70 procedures in Chile later extending to a total of 544 procedures. We think that a fundamental first step to improve IC radiation safety in Chile, would be to revise and update legislation on the use of ionizing radiation, including the implementation of quality assurance programs and training in radiation protection according to those involved in IC procedures

    To examine the association between hospital market concentration and pricing. Hospitals have been merging into systems that potentially wield bargaining power over private health insurers. Concern is growing among policy makers that these systems may respond to provisions of the 2010 health reform legislation by further increasing consolidation and prices. Multivariate statistical methods were used to evaluate the association between hospital market concentration, prices, and profits (contribution margins) for commercially insured patients admitted for any of 6 major cardiac and orthopedic surgery procedures, adjusting for characteristics of the patient (diagnoses, comorbidities,complications) and of the hospital (size, patient volume, teaching status). Data were obtained on 11,330 patients treated in 61 hospitals in 27 markets across 8 states in 2008. Hospital prices for patients in concentrated markets were higher than hospital prices for otherwise-comparable patients in competitive markets by 25.1% for coronary angioplasty, 13.0%for cardiac rhythm management (CRM) device insertion, 19.2% for total knee replacement, 24.1%for total hip replacement, 19.3% for lumbar spine fusion, and 22.7% for cervical spine fusion (P markets by $5259 for angioplasty, $3417 for CRM device insertion, $4123 for total knee replacement, $5889 for total hip replacement, $7931 for lumbar spine fusion, and $4663 for cervical spine fusion (P markets charge significantly higher prices and earn significantly higher margins from private insurers than do hospitals in competitive markets.

    C-arm computed tomography is currently being introduced into cardiac imaging and offers the potential for three-dimensional imaging of the cardiac anatomy within the interventional environment. This detailed view is necessary to support complex interventional strategies, such as transcutaneous valve replacement, interventional therapy of atrial fibrillation, implantation of biventricular pacemakers and assessment of myocardial perfusion. Currently, the major limitation of this technology is its insufficient temporal resolution which limits the visualization of fast moving parts of the heart. (orig.) [de

    In referring to issues confronting the energy field in this region and options to be exercised in the future, I would like to mention the fundamental condition of the utmost importance. That can be summed up as follows: any subject in energy area can never be solved by one country alone, given the geographical and geopolitical characteristics intrinsically possessed by energy. So, a regional approach is needed and it is especially necessary for the main players in the region to jointly address problems common to them. Though it may be a matter to be pursued in the distant future, I am personally dreaming a 'Common Energy Market for Northeast Asia,' in which member countries' interests are adjusted so that the market can be integrated and the region can become a most economically efficient market, thus formulating an effective power to encounter the outside. It should be noted that Europe needed forty years to integrate its market as the unified common market. It is necessary for us to follow a number of steps over the period to eventually materialize our common market concept, too. Now is the time for us to take a first step to lay the foundation for our descendants to enjoy prosperity from such a common market.

    To evaluate postgraduate training period, social life and problems of cardiology residents in Turkey by using a questionnaire form and to compare with the core curriculum of European Society of Cardiology for general cardiology. Overall, 529 residents of cardiology ages in range of 24-35 years (mean age: 26.5±2.0 years, 81.4% male) participated as volunteers in this cross-sectional survey study. An 86-item questionnaire form was used to evaluate the education process, capacity of knowledge and skill and social effectiveness level of participants. The questionnaire were composed both closed- and open-ended questions. The questionnaire form was filled in with the face-to-face communication method. The data of survey were compared with the core curriculum of European Society of Cardiology for general cardiology training period. Chi-square or Fischer exact test was used for statistical analysis. The participants were working in various university hospitals (70.3%) and training-research (state) hospitals in 31 different provinces in Turkey (40.8% in Marmara region). They visited 40±10 outpatients and 10±5 hospitalized pts daily in the clinics. The 3-5 residents worked at the clinic on night shifts and mostly (89%) 8 or more night shifts per month were held in their first training years. During first three-years of training 76% of residents have performed echocardiography, 40.8%-transesophageal echocardiography and 10% - intraoperative echocardiography. The 84.3% of them evaluated exercise tests, 76.4%-Holter electrocardiography and 53.3%-tilt-table tests. The rate of residents working in coronary angiography laboratories was 54.3%. The 53.7% of residents performed coronary angiography and 64%-only in the 4th year of their training. The number of coronary angiography performance was under expected when compared with European Society of Cardiology curriculum. The 18.5% of residents were participated as assistant researcher in an international multi-center study and

    The Adult Congenital and Pediatric Cardiology (AC/PC) Section was established to develop a clear voice within the American College of Cardiology and address the myriad issues facing the congenital heart disease profession. The Section is governed by the AC/PC Council, which includes pediatric cardiologists, adult congenital cardiologists, a cardiac care associate, and a fellow-in-training member. The Council is responsible for bidirectional communication between the College's Board of Trustees and the AC/PC Section members. Since its founding in 2004, Section objectives have been defined by the College's mission: to advocate for quality cardiovascular care through education, research promotion, and the development and application of standards and guidelines and to influence health care policy. The pillars of the College-advocacy, quality, education, and member engagement-serve as the defining template for the Section's strategy. The Section has developed work groups in advocacy, clinical practice, education and training, quality, and publications. A separate leadership group has been developed for adult congenital heart disease. Work groups are open to all Section members. Recognition of the importance of lifelong care in congenital heart disease led Section leaders to incorporate pediatric cardiology and adult congenital heart disease content into each of the work groups. There are more than 1,200 Section members, with nearly 400 members actively contributing to Section activities. This article outlines Section efforts to date and highlights significant successes to date. Copyright © 2012 American College of Cardiology Foundation. Published by Elsevier Inc.

    2005-01-01

    As in previous years, the year 2003 was notable for clinical studies confirming the position occupied by Nuclear Cardiology and MRI in patient management. This was confirmed in the different areas tackled this year. In myocardial ischaemia, 2 points attracted our attention. Firstly, there is the good prognostic value of a normal myocardial perfusion (stress) CT with tetrofosmin (Myoview), which makes the good prognostic value of a normal SPECT independent of the type of tracer used ( 201 Tl, 99m Tc - MIBI, 99m Tc - Tetrofosmine). Secondly, an elegant study performed in 10627 patients, once more confirming the significance of using stress SPECT in the therapeutic strategy (medical treatment versus revascularization). Furthermore, in the area of myocardial infarction (MI), 3 points attracted our attention : the use of Annexin A5 - 99m Tc was advantageous for visualizing apoptosis in the territory at risk, the limits of studying regional myocardial function versus contrast MRI in the diagnosis of MI, and the good sensitivity of contrast MRI in the detection of sub-endocardial MI. In the diagnosis of acute coronary syndrome, one study reported the sensitivity and specificity of emergency MRI (84 versus 85%). In the area of myocardial viability, one study reported the inferiority of electromechanical mapping compared to SPECT and positron emission tomography. In the area of post-infarct cardiac failure, studies have confirmed the place of LVEF in the evaluation of prognosis, and combining this with BNP and possibly the study of the angiotensin converting enzyme gene. Similarly another study reported the superiority of MIBG-1231 compared to cardiac frequency variability in the evaluation of prognosis. (author)

    Nuclear cardiology is widely used to diagnose coronary artery disease and to guide patient management, but data on current practices, radiation dose-related best practices, and radiation doses are scarce. To address these issues, the IAEA conducted a worldwide study of nuclear cardiology practice. We present the European subanalysis. In March 2013, the IAEA invited laboratories across the world to document all SPECT and PET studies performed in one week. The data included age, gender, weight, radiopharmaceuticals, injected activities, camera type, positioning, hardware and software. Radiation effective dose was calculated for each patient. A quality score was defined for each laboratory as the number followed of eight predefined best practices with a bearing on radiation exposure (range of quality score 0 - 8). The participating European countries were assigned to regions (North, East, South, and West). Comparisons were performed between the four European regions and between Europe and the rest-of-the-world (RoW). Data on 2,381 European patients undergoing nuclear cardiology procedures in 102 laboratories in 27 countries were collected. A cardiac SPECT study was performed in 97.9 % of the patients, and a PET study in 2.1 %. The average effective dose of SPECT was 8.0 ± 3.4 mSv (RoW 11.4 ± 4.3 mSv; P cardiology is lower and the average quality score is higher than in the RoW. There is regional variation in effective dose in relation to the best practice quality score. A possible reason for the differences between Europe and the RoW could be the safety culture fostered by actions under the Euratom directives and the implementation of diagnostic reference levels. Stress-only imaging and weight-adjusted activity might be targets for optimization of European nuclear cardiology practice.

    Many hospitals experience a reduction in the number of available physicians on days when national scientific meetings are conducted. This study investigates the relationship between in-hospital mortality in acute myocardial infarction (AMI) patients and admission during national cardiology meeting dates. Using an administrative database, we analyzed patients with AMI admitted to acute care hospitals in Japan from 2011 to 2013. There were 3 major national cardiology meetings held each year. A hierarchical logistic regression model was used to compare in-hospital mortality and treatment patterns between patients admitted on meeting dates and those admitted on identical days during the week before and after the meeting dates. We identified 6,332 eligible patients, with 1,985 patients admitted during 26 meeting days and 4,347 patients admitted during 52 non-meeting days. No significant differences between meeting and non-meeting dates were observed for in-hospital mortality (7.4% vs. 8.5%, respectively; p=0.151, unadjusted odds ratio: 0.861, 95% confidence interval: 0.704-1.054) and the proportion of percutaneous coronary intervention (PCI) performed on the day of admission (75.9% vs. 76.2%, respectively; p=0.824). We also found that some low-staffed hospitals did not treat AMI patients during meeting dates. Little or no "national meeting effect" was observed on in-hospital mortality in AMI patients, and PCI rates were similar for both meeting and non-meeting dates. Our findings also indicated that during meeting dates, AMI patients may have been consolidated to high-performance and sufficiently staffed hospitals. Copyright © 2016 Elsevier Ireland Ltd.

    in-hospital life-threatening ventricular arrhythmias (LT-VA) may complicate the course of cardiovascular patients. We aimed to assess the incidence, circumstances, determinants, and outcome of in-hospital LT-VA in order to help clinicians in prescribing appropriate levels of monitoring. the study population consisted of all 10,741 consecutive patients (65 ± 15 years, 67.7% males) admitted to a cardiology department in 2009-2014. Terminally ill patients and those with primary arrhythmia diagnosis were excluded. The composite end-point included sudden arrhythmic death, ventricular fibrillation, unstable ventricular tachycardia and appropriate ICD shock unrelated to invasive interventions. the incidence of LT-VA was 0.6%, with no differences regarding age, gender and primary diagnosis of coronary artery disease between patients with and without LT-VA. The incidence of LT-VA was significantly higher (1.2% versus 0.1%, p<0.001) among urgent compared with elective admissions and among patients with left ventricular ejection fraction (LV-EF) <45% (1.7% versus 0.2%, p<0.001). At multivariable analysis, urgent admission and LV-EF <45%, but not primary diagnosis of coronary artery disease, remained independent predictors of LT-VA. At the time of the event, 97.1% fulfilled either class I or class II indications for telemetry monitoring according to the American Heart Association guidelines. Survival to discharge with good neurological status was 70.6%. acutely ill patients with heart failure and LV systolic dysfunction showed the highest rate of LT-VAs, regardless of the underlying cardiac disease (ischemic or non-ischemic). Current guidelines demonstrated high sensitivity in identifying patients at risk. These findings may favor proper utilization of telemetry monitoring resources. Copyright © 2016.

    The MANAS trial evaluated the effectiveness of a lay counselor led collaborative stepped care intervention for Common Mental Disorders (CMD) in public and private sector primary care settings in Goa, India. This paper describes the qualitative findings of the experience of the intervention and its impact on health and psychosocial outcomes. Twenty four primary care facilities (12 public and private each) were randomized to provide either collaborative stepped care (CSC) or enhanced usual care (EUC) to adults who screen positive for CMDs. Participants were sampled purposively based on two criteria: gender and, in the CSC arm, adherence with the intervention. The qualitative study component involved two semi-structured interviews with participants of both arms (N = 115); the first interview within 2 months of recruitment and the second 6-8 months after recruitment. Data were collected between September 2007 and November 2009. More participants in the CSC than EUC arm reported relief from symptoms and an improvement in social functioning and positive impact on work and activities of daily life. The CSC participants attributed their improvement both to medication received from the doctors and the strategies suggested by the lay Health Counselors (HC). However, two key differences were observed in the results for the two types of facilities. First, the CSC participants in the public sector clinics were more likely to consider the HCs to be an important component of providing care who served as a link between patient and the doctor, provided them skills on stress management and helped in adherence to medication. Second, in the private sector, doctors performed roles similar to those of the HCs and participants in both arms placed much faith in the doctor who acted as a confidante and was perceived to understand the participant's health and context intimately. Lay counselors working in a CSC model have a positive effect on symptomatic relief, social functioning and

    There is growing concern about radiation exposure from nuclear myocardial perfusion imaging (MPI), particularly among younger patients who are more prone to develop untoward effects of ionizing radiation, and hence US and European professional society guidelines recommend age as a consideration in weighing radiation risk from MPI. We aimed to determine how patient radiation doses from MPI vary across age groups in a large contemporary international cohort. Data were collected as part of a global cross-sectional study of centers performing MPI coordinated by the International Atomic Energy Agency (IAEA). Sites provided information on each MPI study completed during a single week in March-April 2013. We compared across age groups laboratory adherence to pre-specified radiation-related best practices, radiation effective dose (ED; a whole-body measure reflecting the amount of radiation to each organ and its relative sensitivity to radiation's deleterious effects), and the proportion of patients with ED ≤ 9 mSv, a target level specified in guidelines. Among 7911 patients undergoing MPI in 308 laboratories in 65 countries, mean ED was 10.0 ± 4.5 mSv with slightly higher exposure among younger age groups (trend p value < 0.001). There was no difference in the proportion of patients with ED ≤ 9 mSv across age groups, or in adherence to best practices based on the median age of patients in a laboratory. In contemporary nuclear cardiology practice, the age of the patient appears not to impact protocol selection and radiation dose, contrary to professional society guidelines. Copyright © 2018.

    Objectives The relationship between preoperative medical consultations and postoperative complications has not been extensively studied. Thus, we investigated the impact of preoperative consultation on postoperative morbidity following elective abdominal aortic aneurysm repair. Methods A retrospective review was conducted on 469 patients (mean age 72 years, 20% female) who underwent elective abdominal aortic aneurysm repair from June 2007 to July 2014. Data elements included detailed medical history, preoperative cardiology consultation, and postoperative complications. Primary outcomes included 30-day morbidity, consult-specific morbidity, and mortality. A bivariate probit regression model accounting for the endogeneity of binary preoperative medical consult and patient variability was estimated with a maximum likelihood function. Results Eighty patients had preoperative medical consults (85% cardiology); thus, our analysis focuses on the effect of cardiac-related preoperative consults. Hyperlipidemia, increased aneurysm size, and increased revised cardiac risk index increased likelihood of referral to cardiology preoperatively. Surgery type (endovascular versus open repair) was not significant in development of postoperative complications when controlling for revised cardiac risk index ( p = 0.295). After controlling for patient comorbidities, there was no difference in postoperative cardiac-related complications between patients who did and did not undergo cardiology consultation preoperatively ( p = 0.386). Conclusions When controlling for patient disease severity using revised cardiac risk index risk stratification, preoperative cardiology consultation is not associated with postoperative cardiac morbidity.

    The cardiology and field of cardiovascular approaches are often mentioned as of the earliest concerns throughout the history of mankind civilization. During the golden ages of Islamic era, 9th to 12th centuries A.D., medical knowledge from various fields including cardiology was flourished by prominent Persian physicians and scholars. Among those outstanding physicians and scientists of the Islamic golden era, Avicenna is known as a famous and pioneer character. To outline the cardiovascular knowledge and contribution of Avicenna, current review compiled all his evidence-based concepts of cardiovascular findings from current medical literatures as well as those mentioned in his important medical encyclopedia, the Canon of Medicine. In this review, Avicenna's findings on cardiovascular anatomy such as his description of Willis circle, capillary circulation and arterial and ventricular contractions in the cardiovascular system have been mentioned. Also, his books and manuscripts on cardiology as well as findings and theories on cardiovascular and allied diseases were discussed. These findings are included in his descriptions on cardiac tamponade, stroke, palpitation, atherosclerosis, hypertension, association of the cardiovascular complications with erection and ejaculation, interaction between the heart and emotions as well as some of his mentioned drugs for cardiological disorders and the early concepts of drug targeting. These results can show Avicenna's great contribution to improve the sciences of cardiology in early medieval era. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    To address perspectives of cardiology fellows on the current state of palliative education and palliative and hospice resource utilization within their fellowship experiences. We conducted an online national survey of cardiology fellows during the 2015 to 2016 academic year. Survey questions aimed to assess perceived importance of palliative care education, level of palliative care education during fellowship, and the structure of palliative care support at respondent institutions. Responses were collected anonymously. A total of 519 programs, including subspecialty programs, were contacted. We received 365 responses, a number that represents roughly 14% of all cardiology fellows nationwide during the 2015 to 2016 academic year. Fellows reported discordance in the quality of education between general cardiology and palliative care principles as it relates to care of the patient approaching the end of life. Fellows infrequently received explicit training nor were observed or mentored in delivering end-of-life discussions. Respondents reported an underutilization of palliative care and hospice resources during fellowship training and also a perception that attending faculty were not routinely addressing goals of care. Our survey results highlight a need for enhanced palliative care and end-of-life training experiences for cardiology fellows and also suggest underutilization of hospice and palliative care resources for patients with advanced cardiac diseases. These findings create a platform for future work that might: (1) confirm this training deficit, (2) lead to exploration of educational models that could reconcile this deficit, and (3) potentially help improve palliative care support for patients and families facing advanced heart disease.

    Background/Objectives: The specific credentials and continuing education (CME/CE) of nuclear cardiology laboratory medical and technical staff are important factors in the delivery of quality imaging services that have not been systematically evaluated. Methods: Nuclear cardiology accreditation application data from the Intersocietal Accreditation Commission (IAC) was used to characterize facilities performing myocardial perfusion imaging by setting, size, previous accreditation and credentials of the medical and technical staff. Credentials and CME/CE were compared against initial accreditation decisions (grant or delay) using multivariable logistic regression. Results: Complete data were available for 1913 nuclear cardiology laboratories from 2011-2014. Laboratories with initial positive accreditation decisions had a greater prevalence of Certification Board in Nuclear Cardiology (CBNC) certified medical directors and specialty credentialed technical directors. Certification and credentials of the medical and technical directors, respectively, staff CME/CE compliance, and assistance of a consultant with the application were positively associated with accreditation decisions. Conclusion: Nuclear cardiology laboratories directed by CBNC-certified physicians and NCT- or PET-credentialed technologists were less likely to receive delay decisions for MPI. CME/CE compliance of both the medical and technical directors was associated with accreditation decision. Medical and technical directors' years of experience were not associated with accreditation decision. Copyright © 2017 by the Society of Nuclear Medicine and Molecular Imaging, Inc.

Since poor medication adherence is a complex problem with many contributing causes, there is no one universal solution. This paper describes interventions that were not only effective in improving medication adherence among patients with diabetes, but were also potentially scalable (ie, easy to implement to a large population. We identify key characteristics that make these interventions effective and scalable. This information is intended to inform healthcare systems seeking proven, low resource, cost-effective solutions to improve medication adherence.

    The present of nuclear cardiology techniques with gated-SPECT, positron emission tomography, cardiac magnetic resonance, cardiac mIBG scintigraphy and anatomical and functional images of three-dimensional SPECT-CT fusion may be the future for some centers, a future more or less distant for others. The prediction of the ways that will be followed by the different radioisotope scans in the field of cardiology is to some extent uncertain and depends on the development of other noninvasive techniques and on the possibility of reducing the dose of irradiation, decreasing the undesirable effects of ischemia-inducing drugs, but also on the evolution of macroeconomics in different countries, and of course on the level of experience and excellence in nuclear cardiology laboratories and the confidence generated on clinical cardiologists.

    Cardiovascular services are the third largest source of Medicare spending. We examined the rate of cardiovascular service utilization in the community of Glendale, CA, compared with the nearest academic medical center, the University of Southern California. Publicly available utilization data released by Medicare for the years 2012 and 2013 were used to identify all inpatient and outpatient cardiology services provided in each practice setting. The analysis included 19 private and 17 academic cardiologists. In unadjusted analysis, academic physicians performed half as many services per Medicare beneficiary per year as those in private practice: 2.3 versus 4.8, p cardiology practice settings in southern California, medical service utilization per Medicare beneficiary was nearly 2-fold higher in private practice than in the academic setting, suggesting that there may be opportunity for substantially reducing costs of cardiology care in the community setting.

    The field of nuclear cardiology has changed considerably over recent years, with greater attention paid to safety and radiation protection issues. The wider usage of technetium-99m (Tc-99m)-labeled radiopharmaceuticals for single-photon emission computed tomography (SPECT) imaging using gamma cameras has contributed to better quality studies and lower radiation exposure to patients. Increased availability of tracers and scanners for positron emission tomography (PET) will help further improve the quality of studies and quantify myocardial blood flow and myocardial flow reserve, thus enhancing the contribution of non-invasive imaging to the management of coronary artery disease. The introduction of new instrumentation such as solid state cameras and new software will help reduce further radiation exposure to patients undergoing nuclear cardiology studies. Results from recent studies, focused on assessing the relationship between best practices and radiation risk, provide useful insights on simple measures to improve the safety of nuclear cardiology studies without compromising the quality of results.

    Pediatric syncope is common. Cardiac causes are rarely found. We describe and assess a pragmatic approach to these patients first seen by a pediatric cardiologist in the New England region, using Standardized Clinical Assessment and Management Plans (SCAMPs). Ambulatory patients aged 7 to 21 years initially seen for syncope at participating New England Congenital Cardiology Association practices over a 2.5-year period were evaluated using a SCAMP. Findings were iteratively analyzed and the care pathway was revised. The vast majority (85%) of the 1254 patients had typical syncope. A minority had exercise-related or more problematic symptoms. Guideline-defined testing identified one patient with cardiac syncope. Syncope Severity Scores correlated well between physician and patient perceived symptoms. Orthostatic vital signs were of limited use. Largely incidental findings were seen in 10% of ECGs and 11% of echocardiograms. The 10% returning for follow-up, by design, reported more significant symptoms, but did not have newly recognized cardiac disease. Iterative analysis helped refine the approach. SCAMP methodology confirmed that the vast majority of children referred to the outpatient pediatric cardiology setting had typical low-severity neurally mediated syncope that could be effectively evaluated in a single visit using minimal resources. A simple scoring system can help triage patients into treatment categories. Prespecified criteria permitted the effective diagnosis of the single patient with a clear cardiac etiology. Patients with higher syncope scores still have a very low risk of cardiac disease, but may warrant attention. © 2016 The Authors.

    Cardiovascular disease is the most common cause of mortality and morbidity in the world, but the pharmaceutical industry's willingness to invest in this field has declined because of the many challenges involved with bringing new cardiovascular drugs to market, including late-stage failures, escalating regulatory requirements, bureaucracy of the clinical trial business enterprise, and limited patient access after approval. This contrasts with the remaining burden of cardiovascular disease in Europe and in the world. Thus, clinical cardiovascular research needs to adapt to address the impact of these challenges in order to ensure development of new cardiovascular medicines. The present paper is the outcome of a two-day workshop held by the Cardiovascular Round Table of the European Society of Cardiology. We propose strategies to improve development of effective new cardiovascular therapies. These can include (i) the use of biomarkers to describe patients who will benefit from new therapies more precisely, achieving better human target validation; (ii) targeted, mechanism-based approaches to drug development for defined populations; (iii) the use of information technology to simplify data collection and follow-up in clinical trials; (iv) streamlining adverse event collection and reducing monitoring; (v) extended patent protection or limited rapid approval of new agents to motivate investment in early phase development; and (vi) collecting data needed for health technology assessment continuously throughout the drug development process (before and after approval) to minimize delays in patient access. Collaboration across industry, academia, regulators, and payers will be necessary to enact change and to unlock the existing potential for cardiovascular clinical drug development. A coordinated effort involving academia, regulators, industry, and payors will help to foster better and more effective conduct of clinical cardiovascular trials, supporting earlier
