    综述目的:在确诊为高血压的患者中应用他汀类药物降LDL胆固醇的两项大型临床试验中,比较其试验设计、过程及结果.将这次结果纳入先前进行的关于降低胆固醇的临床试验,并对高血压患者亚组进行分析. 最新发现:预防心肌梗死的降压和降脂治疗临床试验(the AntihypertensiVe andLipid-Lowering Treatment to Prevent Heart Attack Trial,ALLHAT-LLT)中尚未发现引起总死亡率(主要终点),心血管死亡率及心血管事件的发生率明显的下降.该结果与英-斯堪的纳维亚心脏病后果研究的临床试验(theAnglo-Scandinavian Cardiac Outcomes Trial,ASCOT-LLA)的研究结果大相径庭.后者曾因冠心病死亡率及心梗发生率(主要终点)显著下降(36%)而提前终止试验.ASCOT-LLA还表明卒中的发生率明显下降(27%),同时使各种主要的血管事件发生率下降.这两次的试验条件相似,均包括10000人以上确诊为高血压并需药物治疗的患者;二者的治疗均选用单一固定剂量他汀类药物,前者为普伐他汀(40mg/d),后者为阿伐他汀(10mg/d).两次试验的主要差别在于ASCOT-LLA的对照组使用的是安慰剂,双盲设计,而ALLHAT-LLT的对照组则仍为常规治疗.总结:ASCOT-LLA试验结果的确表明在高血压患者中服用降脂药物能使LDL胆固醇明显降低并维持其在较低水平.而ALLHAT-LLT则因为未使用更为有效的药物,对照组中常规应用他汀类药物(剂量逐渐加大),缺乏对比效果而无法获得与ASCOT-LLA相同的结果.

  10. The Birth of Applied Linguistics: The Anglo-Scandinavian School as Discourse Community

    Linn, Andrew R


    The major claim of this article is that there is an independent and clearly defined chapter in the development of linguistics, beginning in the 1880s, which represents the birth of modern applied linguistics, and which has been overlooked in linguistic historiography because of the comparative marginalisation of applied linguistics in the literature. This is the Anglo-Scandinavian School, a phrase its members used to describe themselves. Pioneers within phonetics, these linguists applied thei...

  11. Anglian and Anglo-Scandinavian Cottam: linking digital publication and archive

    Julian D. Richards


    Full Text Available The presence of Anglian and Anglo-Scandinavian settlements at Cottam, East Yorkshire, was first indicated in 1987 by numerous finds of copper alloy coins, dress pins and strap ends by metal detector users. This report presents the results of fieldwork carried out on behalf of the Department of Archaeology, University of York, between 1993-5, including field walking, geophysical survey, and excavation. This revealed an enclosure of the eighth-ninth centuries, containing traces of a small number of post-built halls. In the late ninth century this settlement was then abandoned, a process which led to the incorporation of a human female skull in a domestic rubbish pit. A new enclosed settlement was laid out nearby, which was occupied briefly in the early tenth century. It is argued that the Anglian settlement may have been part of a royal multiple estate but that as a result of estate reorganisation after the Scandinavian settlement it developed into an independent manor. Cottam is the first so-called "productive site" in the environs of York to be the subject of archaeological investigations. The results suggest that it was a prosperous but not exceptional site, and that the primary activity was farming, with limited evidence for trade or manufacture. This work also prompts a reassessment of the typology of crop mark enclosures and the re-examination of the large number of undated enclosures in the area.

  13. Cardiac surgery outcomes.

    Halpin, Linda S; Barnett, Scott D; Beachy, Jim


    Accrediting organizations and payers are demanding valid and reliable data that demonstrate the value of services. Federal agencies, healthcare industry groups, and healthcare watchdog groups are increasing the demand for public access to outcomes data. A new and growing outcomes dynamic is the information requested by prospective patients in an increasingly consumer-oriented business. Patients demand outcomes, and resources are developing to meet these demands. Physicians are increasingly confronted with requests for information about their mortality and morbidity rates, malpractice suits, and disciplinary actions received. For example, in Virginia, prospective patients have access to data provided by the nonprofit group Virginia Health Information. After numerous resolutions by the Virginia Senate since 1999, the prospective Virginia medical consumer now has access to several annual publications: Virginia Hospitals: A Consumer's Guide, 1999 Annual Report and Strategic Plan Update, and the 1999 Industry Report: Virginia Hospitals and Nursing Facilities. Consumers have access to cardiac outcomes data stratified by hospital, gender, and cardiac service line (cardiac surgery, noninvasive cardiology, and invasive cardiology). This is particularly relevant to IHI because Virginia Health Information specifically targets cardiac care. IHI has a sizable investment in cardiovascular outcomes and has found outcomes measurement and research are key to providing quality care. IHI's goal is to move from an outcomes management model to a disease management model. The hope is to incorporate all aspects of the patient's continuum of care, from preoperative and diagnostic services through cardiac interventions to postoperative rehabilitation. Furthermore, every step along the way will be supported with functional status and quality of life assessments. Although these goals are ambitious and expensive, the return on investment is high.

  17. Hypothermia improves outcome from cardiac arrest.

    Bernard, S A


    Out-of-hospital cardiac arrest is common and patients who are initially resuscitated by ambulance officers and transported to hospital are usually admitted to the intensive care unit (ICU). In the past, the treatment in the ICU consisted of supportive care only, and most patients remained unconscious due to the severe anoxic neurological injury. It was this neurological injury rather than cardiac complications that caused the high rate of morbidity and mortality. However, in the early 1990's, a series of animal experiments demonstrated convincingly that mild hypothermia induced after return of spontaneous circulation and maintained for several hours dramatically reduced the severity of the anoxic neurological injury. In the mid-1990's, preliminary human studies suggested that mild hypothermia could be induced and maintained in post-cardiac arrest patients without an increase in the rate of cardiac or other complications. In the late 1990's, two prospective, randomised, controlled trials were conducted and the results confirmed the animal data that mild hypothermia induced after resuscitation and maintained for 12 - 24 hours dramatically improved neurological and overall outcomes. On the basis of these studies, mild hypothermia was endorsed in 2003 by the International Liaison Committee on Resuscitation as a recommended treatment for comatose patients with an initial cardiac rhythm of ventricular fibrillation. However, the application of this therapy into routine clinical critical care practice has been slow. The reasons for this are uncertain, but may relate to the relative complexity of the treatment, unfamiliarity with the pathophysiology of hypothermia, lack of clear protocols and/or uncertainty of benefit in particular patients. Therefore, recent research in this area has focused on the development of feasible, inexpensive techniques for the early, rapid induction of mild hypothermia after cardiac arrest. Currently, the most promising strategy is a rapid

  18. Neurodevelopmental Outcomes After Cardiac Surgery in Infancy

    Stopp, Christian; Wypij, David; Andropoulos, Dean B.; Atallah, Joseph; Atz, Andrew M.; Beca, John; Donofrio, Mary T.; Duncan, Kim; Ghanayem, Nancy S.; Goldberg, Caren S.; Hövels-Gürich, Hedwig; Ichida, Fukiko; Jacobs, Jeffrey P.; Justo, Robert; Latal, Beatrice; Li, Jennifer S.; Mahle, William T.; McQuillen, Patrick S.; Menon, Shaji C.; Pemberton, Victoria L.; Pike, Nancy A.; Pizarro, Christian; Shekerdemian, Lara S.; Synnes, Anne; Williams, Ismee; Bellinger, David C.; Newburger, Jane W.


    BACKGROUND: Neurodevelopmental disability is the most common complication for survivors of surgery for congenital heart disease (CHD). METHODS: We analyzed individual participant data from studies of children evaluated with the Bayley Scales of Infant Development, second edition, after cardiac surgery between 1996 and 2009. The primary outcome was Psychomotor Development Index (PDI), and the secondary outcome was Mental Development Index (MDI). RESULTS: Among 1770 subjects from 22 institutions, assessed at age 14.5 ± 3.7 months, PDIs and MDIs (77.6 ± 18.8 and 88.2 ± 16.7, respectively) were lower than normative means (each P < .001). Later calendar year of birth was associated with an increased proportion of high-risk infants (complexity of CHD and prevalence of genetic/extracardiac anomalies). After adjustment for center and type of CHD, later year of birth was not significantly associated with better PDI or MDI. Risk factors for lower PDI were lower birth weight, white race, and presence of a genetic/extracardiac anomaly (all P ≤ .01). After adjustment for these factors, PDIs improved over time (0.39 points/year, 95% confidence interval 0.01 to 0.78; P = .045). Risk factors for lower MDI were lower birth weight, male gender, less maternal education, and presence of a genetic/extracardiac anomaly (all P < .001). After adjustment for these factors, MDIs improved over time (0.38 points/year, 95% confidence interval 0.05 to 0.71; P = .02). CONCLUSIONS: Early neurodevelopmental outcomes for survivors of cardiac surgery in infancy have improved modestly over time, but only after adjustment for innate patient risk factors. As more high-risk CHD infants undergo cardiac surgery and survive, a growing population will require significant societal resources. PMID:25917996

    Emergency physicians and intensivists are increasingly utilizing capnography and bedside echocardiography during medical resuscitations. These techniques have shown promise in predicting outcomes in cardiac arrest, and no cases of return of spontaneous circulation in the setting of sonographic cardiac standstill and low end-tidal carbon dioxide have been reported. This case report illustrates an example of such an occurrence. Our aims are to report a case of return of spontaneous circulation ...

  1. Cardiac asthma in elderly patients: incidence, clinical presentation and outcome

    Ray Patrick


    Full Text Available Abstract Background Cardiac asthma is common, but has been poorly investigated. The objective was to compare the characteristics and outcome of cardiac asthma with that of classical congestive heart failure (CHF in elderly patients. Methods Prospective study in an 1,800-bed teaching hospital. Results Two hundred and twelve consecutive patients aged ≥ 65 years presenting with dyspnea due to CHF (mean age of 82 ± 8 years were included. Findings of cardiac echocardiography and natriuretic peptides levels were used to confirm CHF. Cardiac asthma patients were defined as a patient with CHF and wheezing reported by attending physician upon admission to the emergency department. The CHF group (n = 137 and the cardiac asthma group (n = 75, differed for tobacco use (34% vs. 59%, p 2 (47 ± 15 vs. 41 ± 11 mmHg, p Conclusion Patients with cardiac asthma represented one third of CHF in elderly patients. They were more hypercapnic and experienced more distal airway obstruction. However, outcomes were similar.

  2. Outcome of major cardiac injuries at a Canadian trauma center

    Lamy Andre


    Full Text Available Abstract Background Canadian trauma units have relatively little experience with major cardiac trauma (disruption of a cardiac chamber so injury outcome may not be comparable to that reported from other countries. We compared our outcomes to those of other centers. Methods Records of patients suffering major cardiac trauma over a nine-year period were reviewed. Factors predictive of outcome were analyzed. Results Twenty-seven patients (11 blunt and 16 penetrating with major cardiac trauma were evaluated. Injury severity scores (ISS were similar for blunt (49.6 ± 16.6 and penetrating (39.5 ± 21.6, p = 0.20 injuries. Five of 11 blunt trauma patients, and 9 of 16 penetrating trauma patients, had detectable vital signs on hospital arrival (p = 0.43. Ten patients underwent emergency department thoracotomy and 11 patients had cardiac repair in the operating theatre. Eleven patients survived and 16 died. Survivors had a lower ISS (33.7 ± 15.4 than non-survivors (50.4 ± 20.4; p = 0.03. Two of 11 blunt trauma patients and 9 of 16 penetrating trauma patients survived (p = 0.06. Eleven of 14 patients with detectable vital signs survived; all 13 without detectable vital signs died (p = 0.00003. Ten of eleven patients treated in the operating theatre survived, while only one of the other 16 patients survived (p = 0.00002. Conclusions Patients with major cardiac injuries and detectable vital signs on hospital arrival can be salvaged by prompt surgical intervention in the operating theatre. Major cardiac injuries are infrequently encountered at our center but patient survival is comparable to that reported from trauma units in other countries.

  4. Role of Biological Sex in Normal Cardiac Function and in its Disease Outcome – A Review

    Prabhavathi, K.; Selvi, K.Tamarai; Poornima, K.N.; Sarvanan, A.


    Biological sex plays an important role in normal cardiac physiology as well as in the heart‘s response to cardiac disease. Women generally have better cardiac function and survival than do men in the face of cardiac disease; however, this is progressively lost when comparing postmenopausal women with age matched men. Animal model of cardiac disease mirror what is seen in humans. Sex hormones contribute significantly to sex based difference in cardiac functioning and in its disease outcome. Es...

  5. Pediatric defibrillation after cardiac arrest: initial response and outcome

    Rodríguez-Núñez, Antonio; López-Herce, Jesús; García, Cristina; Domínguez, Pedro; Carrillo, Angel; Bellón, Jose María


    Introduction Shockable rhythms are rare in pediatric cardiac arrest and the results of defibrillation are uncertain. The objective of this study was to analyze the results of cardiopulmonary resuscitation that included defibrillation in children. Methods Forty-four out of 241 children (18.2%) who were resuscitated from inhospital or out-of-hospital cardiac arrest had been treated with manual defibrillation. Data were recorded according to the Utstein style. Outcome variables were a sustained return of spontaneous circulation (ROSC) and one-year survival. Characteristics of patients and of resuscitation were evaluated. Results Cardiac disease was the major cause of arrest in this group. Ventricular fibrillation (VF) or pulseless ventricular tachycardia (PVT) was the first documented electrocardiogram rhythm in 19 patients (43.2%). A shockable rhythm developed during resuscitation in 25 patients (56.8%). The first shock (dose, 2 J/kg) terminated VF or PVT in eight patients (18.1%). Seventeen children (38.6%) needed more than three shocks to solve VF or PVT. ROSC was achieved in 28 cases (63.6%) and it was sustained in 19 patients (43.2%). Only three patients (6.8%), however, survived at 1-year follow-up. Children with VF or PVT as the first documented rhythm had better ROSC, better initial survival and better final survival than children with subsequent VF or PVT. Children who survived were older than the finally dead patients. No significant differences in response rate were observed when first and second shocks were compared. The survival rate was higher in patients treated with a second shock dose of 2 J/kg than in those who received higher doses. Outcome was not related to the cause or the location of arrest. The survival rate was inversely related to the duration of cardiopulmonary resuscitation. Conclusion Defibrillation is necessary in 18% of children who suffer cardiac arrest. Termination of VF or PVT after the first defibrillation dose is achieved in a low

  6. Neurodevelopmental outcome after cardiac surgery utilizing cardiopulmonary bypass in children

    Aymen N Naguib


    Full Text Available Introduction: Modulating the stress response and perioperative factors can have a paramount impact on the neurodevelopmental outcome of infants who undergo cardiac surgery utilizing cardiopulmonary bypass. Materials and Methods: In this single center prospective follow-up study, we evaluated the impact of three different anesthetic techniques on the neurodevelopmental outcomes of 19 children who previously underwent congenital cardiac surgery within their 1 st year of life. Cases were done from May 2011 to December 2013. Children were assessed using the Stanford-Binet Intelligence Scales (5 th edition. Multiple regression analysis was used to test different parental and perioperative factors that could significantly predict the different neurodevelopmental outcomes in the entire cohort of patients. Results: When comparing the three groups regarding the major cognitive scores, a high-dose fentanyl (HDF patients scored significantly higher than the low-dose fentanyl (LDF + dexmedetomidine (DEX (LDF + DEX group in the quantitative reasoning scores (106 ± 22 vs. 82 ± 15 P = 0.046. The bispectral index (BIS value at the end of surgery for the -LDF group was significantly higher than that in LDF + DEX group (P = 0.011. For the entire cohort, a strong correlation was seen between the standard verbal intelligence quotient (IQ score and the baseline adrenocorticotropic hormone level, the interleukin-6 level at the end of surgery and the BIS value at the end of the procedure with an R 2 value of 0.67 and P < 0.04. There was an inverse correlation between the cardiac Intensive Care Unit length of stay and the full-scale IQ score (R = 0.4675 and P 0.027. Conclusions: Patients in the HDF group demonstrated overall higher neurodevelopmental scores, although it did not reach statistical significance except in fluid reasoning scores. Our results may point to a possible correlation between blunting the stress response and improvement of the neurodevelopmental

  8. Outcome of children with Pentalogy of Cantrell following cardiac surgery.

    O'Gorman, Clodagh S


    Although single individual reports have documented outcomes in children with pentalogy of are few data available for postoperative outcome of this cohort of patients after cardiac surgery. The aim of this study was to retrospectively review the clinical details of patients with pentalogy of Cantrell managed at two centers. Two cardiac surgical institutions retrospectively studied all patients with pentalogy of Cantrell and significant congenital heart disease who underwent surgical intervention, excluding PDA ligation, between 1992 and 2004. Seven children with pentalogy of Cantrell underwent surgical intervention at a median age of 60 days (range, 1-11 months). Three patients had tetralogy of Fallot, two double outlet right ventricle, one patient had tricuspid atresia, and one patient a perimembranous ventricular septal defect. The mean duration of postoperative ventilation was 112.8 days (range, 4-335 days) but three patients required ventilation for more than 100 days. Patients who had a preoperative diaphragmatic plication required a longer duration of ventilation (mean = 186.5 days [range, 100-273 days] compared with mean = 132 days [range, 4-335 days]). Four patients survived, with three patients weaned from ventilation. Three patients had withdrawal of care following failure to wean from ventilation, following multisystem organ failure, and at the request of their parents. In conclusion, the postoperative care of children with pentalogy of Cantrell after cardiac surgery is often complicated by prolonged need for ventilatory support and multiple postoperative complications. Earlier surgical intervention does not necessarily reduce morbidity and mortality. These data may help in the counseling of parents prior to surgical intervention.

  10. Sternal Wound Infection after Cardiac Surgery: Management and Outcome.

    Marie Dubert

    Full Text Available Sternal Wound Infection (SWI is a severe complication after cardiac surgery. Debridement associated with primary closure using Redon drains (RD is an effective treatment, but data on RD management and antibiotic treatment are scarce.We performed a single-center analysis of consecutive patients who were re-operated for SWI between 01/2009 and 12/2012. All patients underwent a closed drainage with RD (CDRD. Patients with endocarditis or those who died within the first 45 days were excluded from management analysis. RD fluid was cultured twice weekly. Variables recorded were clinical and biological data at SWI diagnosis, severity of SWI based on criteria for mediastinitis as defined by the Centers for Disease Control (CDC, antibiotic therapy, RD management and patient's outcome.160 patients developed SWI, 102 (64% fulfilled CDC criteria (CDC+ and 58 (36% did not (CDC- SWI. Initial antibiotic treatment and surgical management were similar in CDC+ and CDC- SWI. Patients with CDC+ SWI had a longer duration of antibiotic therapy and a mortality rate of 17% as compared to 3% in patients with CDC- SWI (p = 0.025. Rates of superinfection (10% and 9% and need for second reoperation (12% and 17% were similar. Failure (death or need for another reoperation was associated with female gender, higher EuroScore for prediction of operative mortality, and stay in the ICU.In patients with SWI, initial one-stage surgical debridement with CDRD is associated with favorable outcomes. CDC+ and CDC- SWI received essentially the same management, but CDC+ SWI has a more severe outcome.

  11. Teamwork, Communication, Formula-One Racing and the Outcomes of Cardiac Surgery

    Merry, Alan F.; Weller, Jennifer; Mitchell, Simon J.


    Most cardiac units achieve excellent results today, but the risk of cardiac surgery is still relatively high, and avoidable harm is common. The story of the Green Lane Cardiothoracic Unit provides an exemplar of excellence, but also illustrates the challenges associated with changes over time and with increases in the size of a unit and the complexity of practice today. The ultimate aim of cardiac surgery should be the best outcomes for (often very sick) patients rather than an undue focus on...

  12. Effects of music therapy on health-related outcomes in cardiac rehabilitation: a randomized controlled trial.

    Mandel, Susan E; Hanser, Suzanne B; Secic, Michelle; Davis, Beth A


    This study tested effectiveness of music therapy in improving health-related outcomes of cardiac rehabilitation patients. Using a randomized, controlled trial with follow-up, the study was conducted in an outpatient cardiac rehabilitation program in Ohio. Sixty-eight of 103 recruited patients, 30 to 80 years of age, completed the protocol through posttreatment. Physiological and psychological outcomes were measured. Cardiac rehabilitation patients were randomly assigned to cardiac rehabilitation only or to music therapy plus cardiac rehabilitation. Music therapy included musical experiences, counseling, and Music-Assisted Relaxation and Imagery. The null hypothesis of no differences in health-related outcomes between cardiac rehabilitation patients who experienced cardiac rehabilitation with and without music therapy was rejected due to changes in systolic blood pressure pre to post-treatment. Interpretation of changes at 4 months posttreatment in anxiety, general health, and social functioning are limited, due to small sample sizes at follow-up. Pre to post-music therapy session improvements were also reported. Findings suggest that some health-related outcomes may be affected positively by participation in music therapy in addition to cardiac rehabilitation. Attrition contributed to limitations in statistical power. PMID:17645384

    Dixon, Jennifer L.; Papaconstantinou, Harry T.; Hodges, Bonnie; Korsmo, Robyn S.; Jupiter, Dan; Shake, Jay; Sareyyupoglu, Basar; Rascoe, Philip A.; Reznik, Scott I.


    Health care is evolving into a value-based reimbursement system focused on quality and outcomes. Reported outcomes from national databases are used for quality improvement projects and public reporting. This study compared reported outcomes in cardiac and thoracic surgery from two validated reporting databases—the Society of Thoracic Surgeons (STS) database and the National Surgical Quality Improvement Program (NSQIP)—from January 2011 to June 2012. Quality metrics and outcomes included morta...

  14. Hypothermic cardiac arrest: an 11 year review of ED management and outcome.

    Brunette, D D; McVaney, K


    The purpose of this study was to examine the emergency department (ED) management of hypothermic cardiac arrest and its outcome. The medical records of all patients with hypothermic cardiac arrest treated in the ED from January 1, 1988 to January 31, 1999 were retrospectively reviewed. Data collected included initial body temperature, serum potassium, methods of rewarming, return of perfusing rhythm, and morbidity and mortality. Data were analyzed by descriptive methods. Eleven patients were treated in the ED resuscitation room for hypothermic cardiac arrest. Six patients were found in cardiac arrest in the field, one patient arrested during transport, and four patients arrested after ED arrival. The average initial temperature was 79.1 degrees F (range 69.0 degrees F to 86.7 degrees F). Seven patients received an ED thoracotomy with internal cardiac massage and warm mediastinal irrigation. Four patients had airway management in the ED and then direct transport to the operating room for cardiac bypass rewarming. Three of the seven patients who received an ED thoracotomy subsequently went to intraoperative cardiac bypass rewarming. Five of the seven (71.4%) patients who received an ED thoracotomy survived, versus none of the four patients (0%) who went directly to intraoperative cardiac bypass. A direct comparison of immediate ED thoracotomy versus intraoperative cardiac bypass without ED thoracotomy is cautiously made as this was an unmatched and nonrandomized study. Three of the surviving patients underwent intraoperative cardiac bypass rewarming after receiving an ED thoracotomy. In two of these patients a perfusing rhythm had been established after thoracotomy in the ED and before transport to the operating room for cardiac bypass. Only one of seven (14.3%) patients who arrested prehospital survived versus four of four (100%) who arrested in the ED. ED thoracotomy with internal cardiac massage and mediastinal irrigation rewarming is effective in the management

  15. Management and outcome of cardiac and endovascular cystic echinococcosis.

    Marta Díaz-Menéndez


    Full Text Available BACKGROUND: Cystic echinococcosis (CE can affect the heart and the vena cava but few cases are reported. METHODS: A retrospective case series of 11 patients with cardiac and/or endovascular CE, followed-up over a period of 15 years (1995-2009 is reported. RESULTS: Main clinical manifestations included thoracic pain or dyspnea, although 2 patients were asymptomatic. Cysts were located mostly in the right atrium and inferior vena cava. Nine patients were previously diagnosed with disseminated CE. Echocardiography was the diagnostic method of choice, although serology, electrocardiogram, chest X-ray, computed tomography/magnetic resonance imaging and histology aided with diagnosis and follow-up. Nine patients underwent cardiac surgery and nine received long-term antiparasitic treatment for a median duration of 25 months (range 4-93 months. One patient died intra-operatively due to cyst rupture and endovascular dissemination. Two patients died 10 and 14 years after diagnosis, due to pulmonary embolism (PE and cardiac failure, respectively. One patient was lost to follow-up. Patients who had cardiac involvement exclusively did not have complications after surgery and were considered cured. There was only one recurrence requiring a second operation. Patients with vena cava involvement developed PEs and presented multiple complications. CONCLUSIONS: Cardiovascular CE is associated with a high risk of potentially lethal complications. Clinical manifestations and complications vary according to cyst location. Isolated cardiac CE may be cured after surgery, while endovascular extracardiac involvement is associated with severe chronic complications. CE should be included in the differential diagnosis of cardiovascular disease in patients from endemic areas.

  16. Teamwork, communication, formula-one racing and the outcomes of cardiac surgery.

    Merry, Alan F; Weller, Jennifer; Mitchell, Simon J


    Most cardiac units achieve excellent results today, but the risk of cardiac surgery is still relatively high, and avoidable harm is common. The story of the Green Lane Cardiothoracic Unit provides an exemplar of excellence, but also illustrates the challenges associated with changes over time and with increases in the size of a unit and the complexity of practice today. The ultimate aim of cardiac surgery should be the best outcomes for (often very sick) patients rather than an undue focus on the prevention of error or adverse events. Measurement is fundamental to improving quality in health care, and the framework of structure, process, and outcome is helpful in considering how best to achieve this. A combination of outcomes (including some indicators of important morbidity) with key measures of process is advocated. There is substantial evidence that failures in teamwork and communication contribute to inefficiency and avoidable harm in cardiac surgery. Minor events are as important as major ones. Six approaches to improving teamwork (and hence outcomes) in cardiac surgery are suggested. These are: 1) subspecialize and replace tribes with teams; 2) sort out the leadership while flattening the gradients of authority; 3) introduce explicit training in effective communication; 4) use checklists, briefings, and debriefings and engage in the process; 5) promote a culture of respect alongside a commitment to excellence and a focus on patients; 6) focus on the performance of the team, not on individuals.

    Background Our goal was to evaluate the outcomes of kidney transplants from controlled cardiac death donors compared with brain death donors by conducting a meta-analysis of cohort studies.Methods The PubMed database and EMBASE were searched from January 1980 to July 2013 to identify studies that met pre-stated inclusion criteria.Reference lists of retrieved articles were also reviewed.Two authors independently extracted information on the designs of the studies,the characteristics of the study participants,and outcome assessments.Results Nine cohort studies involving 84 398 participants were included in this meta-analysis; 3 014 received kidneys from controlled cardiac death donors and 80 684 from brain death donors.Warm ischemia time was significantly longer for the controlled cardiac death donor group.The incidence of delayed graft function was 2.74 times (P <0.001) greater in the controlled cardiac death donor group.The results are in favor of the brain death donor group on short-term patient and graft survival while this difference became nonsignificant at mid-term and long term.Sensitivity analysis yielded similar results.No evidence of publication bias was observed.Conclusion This meta-analysis of retrospective cohort studies suggests that the outcome after controlled cardiac death donors is comparable with that obtained using kidneys from brain death donors.

    Chaudhry-Waterman, Nadia; Coombs, Sandra; Porras, Diego; Holzer, Ralf; Bergersen, Lisa


    The broad range of relatively rare procedures performed in pediatric cardiac catheterization laboratories has made the standardization of care and risk assessment in the field statistically quite problematic. However, with the growing number of patients who undergo cardiac catheterization, it has become imperative that the cardiology community overcomes these challenges to study patient outcomes. The Congenital Cardiac Catheterization Project on Outcomes was able to develop benchmarks, tools ...

Methods In a prospective study, we assessed insulin resistance and adiponectin levels from preoperative fasting blood samples in 836 patients unde...

  2. Cardiac tumors in a tertiary care cancer hospital: clinical features, echocardiographic findings, treatment and outcomes

    Joseph Swafford


    Full Text Available Cardiac tumors are a rare entity, comprised of tumors with diverse histology and natural history. We report the clinical characteristics, echocardiograhic findings, therapy and outcome of 59 patients with primary and metastatic cardiac tumors. Our institutional echocardiogram data base from 1993 through 2005 was reviewed to identify patients diagnosed with intra-cardiac tumor. A total of 59 patients with cardiac tumors were identified and included in the study. The patient’s characteristics, presenting symptoms, diagnostic tests, location, histology of the tumor, treatment and one year survival rate of this population was collected from the medical records. Of the 59 cardiac tumor cases, 16 (27% were primary cardiac tumors and 43 (73% were secondary cardiac tumors. The most common primary tumor was sarcoma affecting 13 (81% of the 16 cases. Of these, 5 patients were angiosarcoma, 5 unclassified sarcoma, one myxoid sarcoma and 2 maignant fibrous histiocytoma. The mean age at presentation was 41.1 years, and the most common location was right atrium affecting 6 cases (37.5%. The most common symptom of dyspnea was present in 10 (62.5% cases. Eleven (25.6% of the 43 secondary cardiac tumors were metastasis from renal cell carcinoma. The mean age at presentation was 55.4 years. Right atrium was the most frequent location affecting 18 (42% of the 43 patients. The most common presenting symptom was dyspnea in 15 (35% cases. For both primary and secondary tumors, dyspnea was the most common symptom and right atrium was most frequently involved. Sarcoma was the most common primary cardiac tumor while metastasis from renal cell carcinoma was the most common secondary tumor.

  3. Maternal and fetal outcome in pregnant and parturient women with cardiac disease

    Objective: To study the maternal and fetal outcome in pregnant and parturient women with cardiac disease admitted in Armed Forces Institute of Cardiology Rawalpindi. Type of Study: Cross sectional descriptive study. Place and Duration: Armed Forces Institute of Cardiology Rawalpindi Jan 2008 to June 2008. Patients and Methods: All pregnant patients beyond 28 weeks gestation with cardiac disease diagnosed before pregnancy or during the index pregnancy admitted for delivery or with cardiac complications were included in the study. All neonates less than 2.5 kg were taken as low birth weight and deliveries between 28 and 37 weeks were considered preterm. Cardiac patients with pregnancy less than 28 weeks were excluded from the study. Results: Maternal mortality was 5% with 31% mortality in NYHA Class III and IV. Perinatal mortality was 9% and low birth weight babies were 17%.Perinatal mortality was 0% in NYHA Class I and II and 60% in NYHA class III and IV. There was no maternal mortality in booked patients. All patients who expired were unbooked. Conclusion: Functional cardiac status is the most important factor affecting maternal and perinatal outcome. Antenatal booking status of the patient is the next important factor. (author)

    Caruso, A; de Carolis, S; Ferrazzani, S; Paradisi, G; Pomini, F; Pompei, A


    Twenty-one pregnancies in 16 women who conceived after cardiac valve replacement were reviewed. Oral anticoagulants were discontinued before conception or as soon as possible for subcutaneous heparin treatment (8000-14,000 IU every 8-12 h) and resumed in the second trimester until the last period of pregnancy when oral anticoagulants were replaced again by heparin. No therapeutic abortion was performed. The spontaneous abortion rate was found to be 14.3% (3/21). Preterm delivery (< or = 37 weeks) and low birth weight babies (< 2500 g) were 29.4% (5/17) and 35.3% (6/17), respectively, significantly more frequent than those of the control group (P < 0.02 and P < 0.0005). No significant statistical difference was found when the rate of spontaneous abortion [14.3% (3/21)] and the rate of fetal growth retardation [11.8% (2/17)] were compared with the control group. The majority of thromboembolic events (6/7) occurred during heparin regimen in three mothers; one of them subsequently died. No coumarin embryopathy was observed and the physical and mental development in the 16 surviving children was good. This study confirms: (1) the increased rate of preterm delivery and infants weighing < 2500 g; (2) the increased risk of maternal thrombosis related to heparin use; and (3) the good follow-up in the surviving children.

  5. Congestive Cardiac Failure among Nigerian Children; Pattern and Outcome

    Adeola Animasahun


    Full Text Available Background: Congestive Cardiac Failure (CCF is an important cause of morbidity and mortality among children. It results from various causes, but there are only very few reports from the African sub-region. Objectives: This study aimed to define the current trends in the prevalence and causes of CCF among children admitted to the Pediatrics Department of the Lagos State University Teaching Hospital (LASUTH. Patients and Methods;: This prospective study was conducted on all the consecutive patients admitted with diagnosis of CCF between January 2011 and December 2012. The data were analyzed using Microsoft Excel. Mean, median, and standard deviation were calculated as necessary. Continuous and discrete data were analyzed using student t-test and chi-square test, respectively. P < 0.05 was considered as statistically significant. Results: Out of the 5705 children admitted to the Department of Pediatrics of LASUTH, 156 ones (2.73% had CCF. The subjects’ age ranged from 48 hours to 144 months, with the mean age of 37.1 ± 31.94 months. The common causes of CCF were Acute Lower Respiratory Tract Infections (ALRTI (32.0%, Congenital Heart Diseases (CHD (31.4%, and severe anemia (28.8%. Other less common causes were septicaemia (3.84%, acquired heart diseases (3.2%, and renal disorders (0.6%. The rate of mortality was 17.3%, and more than 90% of the deaths occurred within 48 hours of admission. Conclusions: CCF remains a major cause of morbidity and mortality in Pediatric practice in Nigeria, with ALRTI, CHD, and severe anemia being the common causes.

  6. Cardiac Risk Assessment, Morbidity Prediction, and Outcome in the Vascular Intensive Care Unit.

    Dover, Mary


    Objectives: The aim of this study is to examine the predictive value of the Lee revised cardiac risk index (RCRI) for a standard vascular intensive care unit (ICU) population as well as assessing the utility of transthoracic echocardiography and the impact of prior coronary artery disease (CAD) and coronary revascularization on patient outcome. Design: This is a retrospective review of prospectively maintained Vascubase and prospectively collected ICU data. Materials and Methods: Data from 363 consecutive vascular ICU admissions were collected. Findings were used to calculate the RCRI, which was then correlated with patient outcomes. All patients were on optimal medical therapy (OMT) in the form of cardioselective β-blocker, aspirin, statin, and folic acid. Results: There was no relationship found between a reduced ejection fraction and patient outcome. Mortality was significantly increased for patients with left ventricular hypertrophy (LVH) as identified on echo (14.9% vs 6.5%, P = .028). The overall complication rates were significantly elevated for patients with valvular dysfunction. Discrimination for the RCRI on receiver-operating characteristic analysis was poor, with an area under the receiver-operating characteristic curve of .621. Model calibration was reasonable with an Hosmer-Lemeshow Ĉ statistic of 2.726 (P = .256). Of those with known CAD, 41.22% of the patients receiving best medical treatment developed acute myocardial infarction (AMI) compared to 35.3% of those who previously underwent percutaneous cardiac intervention and 23.5% of those who had undergone coronary artery bypass grafting. There was 3-fold increase in major adverse clinical events in patients with troponin rise and LVH. Conclusions: The RCRI\\'s discriminatory capacity is low, and this raises difficulties in assessing cardiac risk in patients undergoing vascular intervention. The AMI is highest in the OMT group without prior cardiac intervention, which mandates protocols to

  8. Insulin resistance, adiponectin and adverse outcomes following elective cardiac surgery: a prospective follow-up study

    Hjortdal Vibeke E


    Full Text Available Abstract Background Insulin resistance and adiponectin are markers of cardio-metabolic disease and associated with adverse cardiovascular outcomes. The present study examined whether preoperative insulin resistance or adiponectin were associated with short- and long-term adverse outcomes in non-diabetic patients undergoing elective cardiac surgery. Methods In a prospective study, we assessed insulin resistance and adiponectin levels from preoperative fasting blood samples in 836 patients undergoing cardiac surgery. Population-based medical registries were used for postoperative follow-up. Outcomes included all-cause death, myocardial infarction or percutaneous coronary intervention, stroke, re-exploration, renal failure, and infections. The ability of insulin resistance and adiponectin to predict clinical adverse outcomes was examined using receiver operating characteristics. Results Neither insulin resistance nor adiponectin were statistically significantly associated with 30-day mortality, but adiponectin was associated with an increased 31-365-day mortality (adjusted odds ratio 2.9 [95% confidence interval 1.3-6.4] comparing the upper quartile with the three lower quartiles. Insulin resistance was a poor predictor of adverse outcomes. In contrast, the predictive accuracy of adiponectin (area under curve 0.75 [95% confidence interval 0.65-0.85] was similar to that of the EuroSCORE (area under curve 0.75 [95% confidence interval 0.67-0.83] and a model including adiponectin and the EuroSCORE had an area under curve of 0.78 [95% confidence interval 0.68-0.88] concerning 31-365-day mortality. Conclusions Elevated adiponectin levels, but not insulin resistance, were associated with increased mortality and appear to be a strong predictor of long-term mortality. Additional studies are warranted to further clarify the possible clinical role of adiponectin assessment in cardiac surgery. Trial Registration The Danish Data Protection Agency; reference no

  9. Predicting the outcomes for out-of-hospital cardiac arrest patients using multiple biomarkers and suspension microarray assays

    Huang, Chien-Hua; Tsai, Min-Shan; Chien, Kuo-Liong; Chang, Wei-Tien; Wang, Tzung-Dau; Chen, Shyr-Chyr; Ma, Matthew Huei-Ming; Hsu, Hsin-Yun; Chen, Wen-Jone


    Predicting the prognosis for cardiac arrest is still challenging. Combining biomarkers from diverse pathophysiological pathways may provide reliable indicators for the severity of injury and predictors of long-term outcomes. We investigated the feasibility of using a multimarker strategy with key independent biomarkers to improve the prediction of outcomes in cardiac arrest. Adult out-of-hospital cardiac arrest patients with sustained return of spontaneous circulation were prospectively enrolled in this study. Blood samples were taken at 2 and 24 hours after cardiac arrest. Suspension microarray assays were used to test 21 different biomarkers. A total of 99 patients were enrolled, 45 of whom survived to hospital discharge. We identified 11 biomarkers that, when combined with clinical variables and factors of APACHE II score and history of arrhythmia, were independent determinants for outcome of in-hospital mortality (concordance = 0.9249, standard error = 0.0779). Three biomarkers combined with APACHE II and age were independent determinants for favorable neurological outcome at hospital discharge (area under the receiver-operator characteristic curve, 0.938; 95% confidence interval, 0.854 ~ 1.0). In conclusion, a systemic multiple biomarker approach using suspension microarray assays can identify independent predictors and model the outcomes of cardiac arrest patients during the post-cardiac arrest period.

  10. Clinical Outcomes and Quality of Life in Recipients of Livers Donated after Cardiac Death

    Neehar D. Parikh


    Full Text Available Donation after cardiac death (DCD has expanded in the last decade in the US; however, DCD liver utilization has flattened in recent years due to poor outcomes. We examined clinical and quality of life (QOL outcomes of DCD recipients by conducting a retrospective and cross-sectional review of patients from 2003 to 2010. We compared clinical outcomes of DCD recipients (n=60 to those of donation after brain death (DBD liver recipients (n=669 during the same time period. DCD recipients had significantly lower rates of 5-year graft survival (P<0.001 and a trend toward lower rates of 5-year patient survival (P=0.064 when compared to the DBD cohort. In order to examine QOL outcomes in our cohorts, we administered the Short Form Liver Disease Quality of Life questionnaire to 30 DCD and 60 DBD recipients. The DCD recipients reported lower generic and liver-specific QOL. We further stratified the DCD cohort by the presence of ischemic cholangiopathy (IC. Patients with IC reported lower QOL when compared to DBD recipients and those DCD recipients without IC (P<0.05. While the results are consistent with clinical experience, this is the first report of QOL in DCD recipients using standardized measures. These data can be used to guide future comparative effectiveness studies.

  11. 60. Mid-term outcome of cardiac resynchronization therapy in pediatrics: single institution experience

    T. Jawadi


    Full Text Available Cardiac resynchronization therapy (CRT has become an increasingly important therapeutic option for patients (pts to treat dyssynchrony associated moderate and severe heart failure. Few reports however, determined the beneficial effects of CRT in pediatrics and midterm outcome following this therapy. Our aim is to assess the mid-term outcomes of CRT in children with evidence of dyssynchrony associated heart failure. Cardiac resynchronization therapy is beneficial in treating congenital heart disease patients who have evidence of dyssynchrony associated heart failure. Retrospective review of 18 consecutive pediatric patients who underwent CRT at our institution between January 2002 and August 2011 Cardiac resynchronization pacemaker was implanted in 18 pts the majority of pts (14 with congenital heart disease. Fourteen pts had preexisting complete heart block and chronic right ventricular pacing. Epicardial left ventricular leads were implanted in all pts while the atrial and right ventricular leads approach varied according to the pt size and anatomy. Indication for CRT was symptomatic dilated cardiomyopathy with evidence of electrical and/or mechanical dyssynchrony demonstrated by M-mode, 3-D echo, or tissue Doppler. The median age of this cohort was 14 years (range 6 months–16 years, the median follow-up time was 7.2 years (range 1–10 years. Subjectively, 16 out of 18 pts reported symptomatic improvement with decreased hospitalizations. The left ventricular ejection fraction improved from mean of 27% (SD 13% to mean of 50% (SD 13% (P value <0.001. Additionally, cardiomegaly improved significantly in during follow up (P value <0.001. The QRS duration with CRT was less but the change is not significant (P value = 0.1 suggesting that electrical resynchronization is not a prerequisite for clinical improvement in this cohort. Children including those with congenital heart disease patients who have evidence of dyssynchrony associated heart

  13. Donor Hemodynamics as a Predictor of Outcomes After Kidney Transplantation From Donors After Cardiac Death.

    Allen, M B; Billig, E; Reese, P P; Shults, J; Hasz, R; West, S; Abt, P L


    Donation after cardiac death is an important source of transplantable organs, but evidence suggests donor warm ischemia contributes to inferior outcomes. Attempts to predict recipient outcome using donor hemodynamic measurements have not yielded statistically significant results. We evaluated novel measures of donor hemodynamics as predictors of delayed graft function and graft failure in a cohort of 1050 kidneys from 566 donors. Hemodynamics were described using regression line slopes, areas under the curve, and time beyond thresholds for systolic blood pressure, oxygen saturation, and shock index (heart rate divided by systolic blood pressure). A logistic generalized estimation equation model showed that area under the curve for systolic blood pressure was predictive of delayed graft function (above median: odds ratio 1.42, 95% confidence interval [CI] 1.06-1.90). Multivariable Cox regression demonstrated that slope of oxygen saturation during the first 10 minutes after extubation was associated with graft failure (below median: hazard ratio 1.30, 95% CI 1.03-1.64), with 5-year graft survival of 70.0% (95%CI 64.5%-74.8%) for donors above the median versus 61.4% (95%CI 55.5%-66.7%) for those below the median. Among older donors, increased shock index slope was associated with increased hazard of graft failure. Validation of these findings is necessary to determine the utility of characterizing donor warm ischemia to predict recipient outcome. PMID:26361242

  14. Risk-taking attitudes and their association with process and outcomes of cardiac care: a cohort study

    Knudtson Merril L


    Full Text Available Abstract Background Prior research reveals that processes and outcomes of cardiac care differ across sociodemographic strata. One potential contributing factor to such differences is the personality traits of individuals within these strata. We examined the association between risk-taking attitudes and cardiac patients' clinical and demographic characteristics, the likelihood of undergoing invasive cardiac procedures and survival. Methods We studied a large inception cohort of patients who underwent cardiac catheterization between July 1998 and December 2001. Detailed clinical and demographic data were collected at time of cardiac catheterization and through a mailed survey one year post-catheterization. The survey included three general risk attitude items from the Jackson Personality Inventory. Patients' (n = 6294 attitudes toward risk were categorized as risk-prone versus non-risk-prone and were assessed for associations with baseline clinical and demographic characteristics, treatment received (i.e., medical therapy, coronary artery bypass graft (CABG surgery, percutaneous coronary intervention (PCI, and survival (to December 2005. Results 2827 patients (45% were categorized as risk-prone. Having risk-prone attitudes was associated with younger age (p Conclusion These exploratory findings suggest that patient attitudes toward risk taking may contribute to some of the documented differences in use of invasive cardiac procedures. An awareness of these associations could help healthcare providers as they counsel patients regarding cardiac care decisions.

  15. Contaminated heparin and outcomes after cardiac surgery: a retrospective propensity-matched cohort study.

    Heiko A Kaiser

    Full Text Available During 2007 and 2008 it is likely that millions of patients in the US received heparin contaminated (CH with oversulfated chondroitin sulfate, which was associated with anaphylactoid reactions. We tested the hypothesis that CH was associated with serious morbidity, mortality, intensive care unit (ICU stay and heparin-induced thrombocytopenia following adult cardiac surgery.We conducted a single center, retrospective, propensity-matched cohort study during the period of CH and the equivalent time frame in the three preceding or the two following years. Perioperative data were obtained from the institutional record of the Society of Thoracic Surgeons National Database, for which the data collection is prospective, standardized and performed by independent investigators. After matching, logistic regression was performed to evaluate the independent effect of CH on the composite adverse outcome (myocardial infarction, stroke, pneumonia, dialysis, cardiac arrest and on mortality. Cox regression was used to determine the association between CH and ICU length of stay. The 1∶5 matched groups included 220 patients potentially exposed to CH and 918 controls. There were more adverse outcomes in the exposed cohort (20.9% versus 12.0%; difference  =  8.9%; 95% CI 3.6% to 15.1%, P < 0.001 with an odds ratio for CH of 2.0 (95% CI, 1.4 to 3.0, P < 0.001. In the exposed group there was a non-significant increase in mortality (5.9% versus 3.5%, difference = 2.4%; 95% CI, -0.4 to 3.5%, P  =  0.1, the median ICU stay was longer by 14.1 hours (interquartile range -26.6 to 79.8, S = 3299, P = 0.0004 with an estimated hazard ratio for CH of 1.2 (95% CI, 1.0 to 1.4, P = 0.04. There was no difference in nadir platelet counts between cohorts.The results from this single center study suggest the possibility that contaminated heparin might have contributed to serious morbidity following cardiac surgery.

  16. Improved Outcome of Cardiac Extracorporeal Membrane Oxygenation in Infants and Children Using Magnetic Levitation Centrifugal Pumps.

    Luciani, Giovanni Battista; Hoxha, Stiljan; Torre, Salvatore; Rungatscher, Alessio; Menon, Tiziano; Barozzi, Luca; Faggian, Giuseppe


    Extracorporeal membrane oxygenation (ECMO) has traditionally been and, for the most part, still is being performed using roller pumps. Use of first-generation centrifugal pumps has yielded controversial outcomes, perhaps due to mechanical properties of the same and the ensuing risk of hemolysis and renal morbidity. Latest-generation centrifugal pumps, using magnetic levitation (ML), exhibit mechanical properties which may have overcome limitations of first-generation devices. This retrospective study aimed to assess the safety and efficacy of veno-arterial (V-A) ECMO for cardiac indications in neonates, infants, and children, using standard (SP) and latest-generation ML centrifugal pumps. Between 2002 and 2014, 33 consecutive neonates, infants, and young children were supported using V-A ECMO for cardiac indications. There were 21 males and 12 females, with median age of 29 days (4 days-5 years) and a median body weight of 3.2 kg (1.9-18 kg). Indication for V-A ECMO were acute circulatory collapse in ICU or ward after cardiac repair in 16 (49%) patients, failure to wean after repair of complex congenital heart disease in 9 (27%), fulminant myocarditis in 4 (12%), preoperative sepsis in 2 (6%), and refractory tachy-arrhythmias in 2 (6%). Central cannulation was used in 27 (81%) patients and peripheral in 6. Seven (21%) patients were supported with SP and 26 (79%) with ML centrifugal pumps. Median duration of support was 82 h (range 24-672 h), with 26 (79%) patients weaned from support. Three patients required a second ECMO run but died on support. Seventeen (51%) patients required peritoneal dialysis for acute renal failure. Overall survival to discharge was 39% (13/33 patients). All patients with fulminant myocarditis and with refractory arrhythmias were weaned, and five (83%) survived, whereas no patient supported for sepsis survived. Risk factors for hospital mortality included lower (<2.5 kg) body weight (P = 0.02) and rescue ECMO after cardiac

  18. Sex, Socioeconomic Status, Access to Cardiac Catheterization and Outcomes for Acute Coronary Syndromes in the Context of Universal Healthcare Coverage

    Fabreau, Gabriel E.; Leung, Alexander A.; Southern, Danielle A.; Knudtson, Merrill L.; McWilliams, J. Michael; Ayanian, John Z.; Ghali, William A.


    Background Sex and neighborhood socioeconomic status (nSES) may independently affect the care and outcomes of acute coronary syndromes (ACS), partly through barriers in timely access to cardiac catheterization. We sought to determine whether sex modifies the association between nSES, and the receipt of cardiac catheterization and mortality following an ACS in a universal healthcare system. Methods and Results We studied 14,012 ACS patients admitted to cardiology services between April 18, 2004 and December 31, 2011 in Southern Alberta, Canada. We used multivariable logistic regression to compare the odds of cardiac catheterization within 2 and 30 days of admission and the odds of 30-day and 1-year mortality for men and women by quintile of neighborhood median household income. Significant relationships between nSES and the receipt of cardiac catheterization and mortality after ACS were detected for women but not men. When examined by nSES, each incremental decrease in neighborhood income quintile for women was associated with a 6% lower odds of receiving cardiac catheterization within 30 days (p=0.01) and a 14% higher odds of 30-day mortality (p=0.03). For men, each decrease in neighborhood income quintile was associated with a 2% lower odds of receiving catheterization within 30 days (p=0.10), and a 5% higher odds of 30-day mortality (p=0.36). Conclusions Associations between nSES and receipt of cardiac catheterization and 30-day mortality were noted for women but not men in a universal healthcare system. Care protocols designed to improve equity of access to care and outcomes are required, especially for low-income women. PMID:24895450

  19. Survival with good neurological outcome in a patient with prolonged ischemic cardiac arrest--utility of automated chest compression systems in the cardiac catheterization laboratory.

    Psaltis, Peter J; Meredith, Ian T; Ahmar, Walid


    The management of refractory cardiac arrest during invasive coronary procedures has substantial logistical challenges and is typically associated with disappointing outcomes. We describe the case of a young woman with recalcitrant ventricular fibrillation due to acute anterior ST-elevation myocardial infarction caused by occlusion of her proximal left anterior descending artery. Survival without neurological deficit or organ failure was achieved following primary percutaneous reperfusion and a total of 52 min of intra-procedural chest compression support, made possible by the use of an automated chest compression device.

    Brawner, Clinton A; Abdul-Nour, Khaled; Lewis, Barry; Schairer, John R; Modi, Shalini S; Kerrigan, Dennis J; Ehrman, Jonathan K; Keteyian, Steven J


    The purpose of this retrospective, observational study was to describe the relation between exercise workload during cardiac rehabilitation (CR), expressed as metabolic equivalents of task (METs), and prognosis among patients with coronary heart disease. We included patients with coronary heart disease who participated in CR between January 1998 and June 2007. METs were calculated from treadmill workload. Cox regression analysis was used to describe the relationship between METs and time to a composite outcome of all-cause mortality, nonfatal myocardial infarction, or heart failure hospitalization. Among 1,726 patients (36% women; median age 59 years [interquartile range, 52 to 66]), there were 467 events (27%) during a median follow-up of 5.8 years (interquartile range, 2.6 to 8.7). In analyses adjusted for age, sex, Charlson co-morbidity index, hypertension, diabetes, and CR referral diagnosis, METs were independently related to the composite outcome at CR start (Wald chi-square 43, hazard ratio 0.59 [95% confidence interval 0.51 to 0.70]) and CR end (Wald chi-square 47, hazard ratio 0.68 [95% confidence interval 0.61 to 0.76]). Patients exercising below 3.5 METs on exit from CR represent a high-risk group with 1- and 3-year event rates ≥7% and ≥18%, respectively. In conclusion, METs during CR is available at no additional cost and can be used to identify patients at increased risk for an event who may benefit from closer follow-up, extended length of stay in CR, and/or participation in other strategies aimed at maximizing adherence to secondary preventive behaviors and improving exercise capacity.

    Fukuda, Tatsuma; Ohashi-Fukuda, Naoko; Matsubara, Takehiro; Doi, Kent; Kitsuta, Yoichi; Nakajima, Susumu; Yahagi, Naoki


    Population aging has rapidly advanced throughout the world and the elderly accounting for out-of-hospital cardiac arrest (OHCA) has increased yearly.We identified all adults who experienced an out-of-hospital cardiac arrest in the All-Japan Utstein Registry of the Fire and Disaster Management Agency, a prospective, population-based clinical registry, between 2005 and 2010. Using multivariable regression, we examined temporal trends in outcomes for OHCA patients by age, as well as the influence of advanced age on outcomes. The primary outcome was a favorable neurological outcome at 1 month after OHCA.Among 605,505 patients, 454,755 (75.1%) were the elderly (≥65 years), and 154,785 (25.6%) were the oldest old (≥85 years). Although neurological outcomes were worse as the age group was older (P < 0.0001 for trend), there was a significant trend toward improved neurological outcomes during the study period by any age group (P < 0.005 for trend). After adjustment for temporal trends in various confounding variables, neurological outcomes improved yearly in all age groups (18-64 years: adjusted OR per year 1.15 [95% CI 1.13-1.18]; 65-84 years: adjusted OR per year 1.12 [95% CI 1.10-1.15]; and ≥85 years: adjusted OR per year 1.08 [95% CI 1.04-1.13]). Similar trends were found in the secondary outcomes.Although neurological outcomes from OHCA ware worse as the age group was older, the rates of favorable neurological outcomes have substantially improved since 2005 even in the elderly, including the oldest old. Careful consideration may be necessary in limiting treatment on OHCA solely for the reason of advanced age. PMID:26656330

    Full Text Available

    The purpose of this study was to evaluate the outcomes for out-of-hospital cardiac arrest (OHCA and cardiopulmonary resuscitation (CPR in the city of Okayama, Japan, during a 1-year period after the reorganization of defibrillation by Emergency Life-Saving Technicians (ELSTs with standing orders of CPR. The data were collected prospectively according to an Utstein style between June 1, 2003 and May 31, 2004; OHCA was confirmed in 363 patients. Cardiac arrest of presumed cardiac etiology (179 was witnessed by a bystander in 62 (34.6% cases. Of this group, ventricular fibrillation (VF was documented in 20 cases (32.3%, and 1 patient (5% was discharged alive without severe neurological disability. This outcome is average in Japan, but it is quite low level compared with Western countries because there is less VF in Japan. The Utstein style revealed that we must try to detect VF before the rhythm changes and to provide defibrillation as soon as possible in order to improve outcomes. Further research will be required to accurately evaluate OHCA in Okayama city.

  6. Determination of the threshold of cardiac troponin I associated with an adverse postoperative outcome after cardiac surgery: a comparative study between coronary artery bypass graft, valve surgery, and combined cardiac surgery

    Fellahi, Jean-Luc; Hedoire, François; Le Manach, Yannick; Monier, Emmanuel; Guillou, Louis; Riou, Bruno


    Introduction The objective of the present study was to compare postoperative cardiac troponin I (cTnI) release and the thresholds of cTnI that predict adverse outcome after elective coronary artery bypass graft (CABG), after valve surgery, and after combined cardiac surgery. Methods Six hundred and seventy-five adult patients undergoing conventional cardiac surgery with cardiopulmonary bypass were retrospectively analyzed. Patients in the CABG (n = 225) and valve surgery groups (n = 225) were selected after matching (age, sex) with those in the combined surgery group (n = 225). cTnI was measured preoperatively and 24 hours after the end of surgery. The main endpoint was a severe postoperative cardiac event (sustained ventricular arrhythmias requiring treatment, need for inotropic support or intraaortic balloon pump for at least 24 hours, postoperative myocardial infarction) and/or death. Data are presented as the median and the odds ratio (95% confidence interval). Results Postoperative cTnI levels were significantly different among the three groups (combined surgery, 11.0 (9.5–13.1) ng/ml versus CABG, 5.2 (4.7–5.7) ng/ml and valve surgery, 7.8 (7.6–8.0) ng/ml; P < 0.05). The thresholds of cTnI predicting severe cardiac event and/or death were also significantly different among the three groups (combined surgery, 11.8 (11.5–14.8) ng/ml versus CABG, 7.8 (6.7–8.8) ng/ml and valve surgery, 9.3 (8.0–14.0) ng/ml; P < 0.05). An elevated cTnI above the threshold in each group was significantly associated with a severe cardiac event and/or death (odds ratio, 4.33 (2.82–6.64)). Conclusion The magnitude of postoperative cTnI release is related to the type of cardiac surgical procedure. Different thresholds of cTnI must be considered according to the procedure type to predict early an adverse postoperative outcome. PMID:17888156

  7. Dextrose containing intravenous fluid impairs outcome and increases death after eight minutes of cardiac arrest and resuscitation in dogs.

    D'Alecy, L G; Lundy, E F; Barton, K J; Zelenock, G B


    Use of dextrose in intravenous resuscitation fluids is common practice; however, this study indicates that 5% dextrose solutions, even if administered in physiologic quantities, greatly worsens the outcome of survivable cardiac arrest. Twelve adult male mongrel dogs were premedicated with morphine, anesthetized with halothane, instrumented, intubated, and ventilated. Each dog was first given 500 ml of either lactated Ringer's (LR) (n = 6) or 5% dextrose in LR (D5LR) (n = 6). Halothane was stopped and fibrillation was induced (60 Hz). Blood glucose just before cardiac arrest was 129 mg/dl in the LR dogs and was increased to 335 mg/dl in the D5LR dogs. After eight minutes of arrest, resuscitation, including internal cardiac massage and standard advanced cardiac life support drug protocols (modified for dogs), was begun. When stable cardiac rhythm was obtained, the chest was closed, and LR or D5LR continued until a total of 1L was given. A neurologic score (0 = normal to 100 = dead) was assigned at 1, 2, 6, and 24 hours. The LR group did not differ statistically from the D5LR group in operative time, number of defibrillatory shocks, time to spontaneous ventilation, time to extubation, or drugs required. Resuscitation was successful in all six LR and five of six D5LR group; however, by 2 hours after resuscitation and thereafter, D5LR group had a significantly greater neurologic deficit (p less than 0.05) than did the LR group. By 9 hours, four of six D5LR dogs displayed convulsive activity and died. At 24 hours the D5LR group had a greater (p less than 0.008) neurologic deficit (82 +/- 11) than did the LR group (21 +/- 7), which walked and ate. We conclude that the addition of 5% dextrose to standard intravenous fluids greatly increases the morbidity and mortality associated with cardiac resuscitation. PMID:3738770

    Jacobsson, Jonatan; Borgquist, Rasmus; Reitan, Christian; Ghafoori, Elyar; Chatterjee, Neal A; Kabir, Muammar; Platonov, Pyotr G; Carlson, Jonas; Singh, Jagmeet P; Tereshchenko, Larisa G


    Cardiac resynchronization therapy (CRT) reduces mortality and morbidity in selected patients with heart failure (HF), but up to 1/3 of patients are nonresponders. Sum absolute QRST integral (SAI QRST) recently showed association with mechanical response on CRT. However, it is unknown whether SAI QRST is associated with all-cause mortality and HF hospitalizations in patients undergoing CRT. The study population included 496 patients undergoing CRT (mean age 69 ± 10 years, 84% men, 65% left bundle branch block [LBBB], left ventricular ejection fraction 23 ± 6%, 63% ischemic cardiomyopathy). Preimplant digital 12-lead electrocardiogram was transformed into orthogonal XYZ electrocardiogram. SAI QRST was measured as an arithmetic sum of areas under the QRST curve on XYZ leads and was dichotomized based on the median value (302 mV ms). All-cause mortality served as the primary end point. A composite of 2-year all-cause mortality, heart transplant, and HF hospitalization was a secondary end point. Cox regression models were adjusted for known predictors of CRT response. Patients with preimplant low mean SAI QRST had an increased risk of both the primary (hazard ratio [HR] 1.8, 95% CI 1.01 to 3.2) and secondary (HR 1.6, 95% CI 1.1 to 2.2) end points after multivariate adjustment. SAI QRST was associated with secondary outcome in subgroups of patients with LBBB (HR 2.1, 95% CI 1.5 to 3.0) and with non-LBBB (HR 1.7, 95% CI 1.0 to 2.6). In patients undergoing CRT, preimplant SAI QRST validation in another prospective cohort, SAI QRST may help to refine selection of CRT recipients. PMID:27265674

  9. Even Four Minutes of Poor Quality of CPR Compromises Outcome in a Porcine Model of Prolonged Cardiac Arrest

    Heng Li


    Full Text Available Objective. Untrained bystanders usually delivered suboptimal chest compression to victims who suffered from cardiac arrest in out-of-hospital settings. We therefore investigated the hemodynamics and resuscitation outcome of initial suboptimal quality of chest compressions compared to the optimal ones in a porcine model of cardiac arrest. Methods. Fourteen Yorkshire pigs weighted 30 ± 2 kg were randomized into good and poor cardiopulmonary resuscitation (CPR groups. Ventricular fibrillation was electrically induced and untreated for 6 mins. In good CPR group, animals received high quality manual chest compressions according to the Guidelines (25% of animal’s anterior-posterior thoracic diameter during first two minutes of CPR compared with poor (70% of the optimal depth compressions. After that, a 120-J biphasic shock was delivered. If the animal did not acquire return of spontaneous circulation, another 2 mins of CPR and shock followed. Four minutes later, both groups received optimal CPR until total 10 mins of CPR has been finished. Results. All seven animals in good CPR group were resuscitated compared with only two in poor CPR group (P<0.05. The delayed optimal compressions which followed 4 mins of suboptimal compressions failed to increase the lower coronary perfusion pressure of five non-survival animals in poor CPR group. Conclusions. In a porcine model of prolonged cardiac arrest, even four minutes of initial poor quality of CPR compromises the hemodynamics and survival outcome.

  10. Impact of advanced cardiac life support training program on the outcome of cardiopulmonary resuscitation in a tertiary care hospital

    Kanwalpreet Sodhi


    Full Text Available Background: Guidelines on performing cardiopulmonary resuscitation (CPR have been published from time to time, and formal training programs are conducted based on these guidelines. Very few data are available in world literature highlighting the impact of these trainings on CPR outcome. Aim: The aim of our study was to evaluate the impact of the American Heart Association (AHA-certified basic life support (BLS and advanced cardiac life support (ACLS provider course on the outcomes of CPR in our hospital. Materials and Methods : An AHA-certified BLS and ACLS provider training programme was conducted in our hospital in the first week of October 2009, in which all doctors in the code blue team and intensive care units were given training. The retrospective study was performed over an 18-month period. All in-hospital adult cardiac arrest victims in the pre-BLS/ACLS training period (January 2009 to September 2009 and the post-BLS/ACLS training period (October 2009 to June 2010 were included in the study. We compared the outcomes of CPR between these two study periods. Results: There were a total of 627 in-hospital cardiac arrests, 284 during the pre-BLS/ACLS training period and 343 during the post-BLS/ACLS training period. In the pre-BLS/ACLS training period, 52 patients (18.3% had return of spontaneous circulation, compared with 97 patients (28.3% in the post-BLS/ACLS training period (P < 0.005. Survival to hospital discharge was also significantly higher in the post-BLS/ACLS training period (67 patients, 69.1% than in the pre-BLS/ACLS training period (12 patients, 23.1% (P < 0.0001. Conclusion : Formal certified BLS and ACLS training of healthcare professionals leads to definitive improvement in the outcome of CPR.

  12. Outcomes after emergency department thoracotomy for penetrating cardiac injuries: a new perspective.

    Molina, Ezequiel J; Gaughan, John P; Kulp, Heather; McClurken, James B; Goldberg, Amy J; Seamon, Mark J


    Previous reports have described penetrating cardiac injuries as the anatomic injury with the greatest opportunity for emergency department thoracotomy (EDT) survival. We hypothesize that actual survival rates are lower than that initially reported. A retrospective review of our EDT experience was performed. Data collected included injury mechanism and location, presence of measurable ED vital signs, initial ED cardiac rhythm, GCS, method of transportation, and survival. Logistic regression analysis identified predictors of survival. Ninety-four of 237 patients presented penetrating cardiac injuries after EDT. Eighty-nine patients (95%) were males. Measurable ED vital signs were present in 15 patients (16%). Cardiac injuries were caused by GSW in 82 patients (87%) and SW in 12 patients (13%). Fifteen patients (16%) survived EDT and were taken to the operating room, while eight patients (8%) survived their entire hospitalization. All survivors were neurologically intact. Survival rates were 5% for GSW and 33% for SW. Mechanism of injury (SW), prehospital transportation by police, higher GCS, sinus tachycardia, and measurable ED vital signs were associated with improved survival. In urban trauma centers where firearm injuries are much more common than stabbings, the presence of a penetrating cardiac injury may no longer be considered a predictor of survival after EDT.

    Background: Cardiac electrophysiologic study and radiofrequency ablation (RFA) have become an established mode of treatment for patients with refractory arrhythmias. These procedures are carried out regularly at the cardiac catheterization laboratory of Madras Medical Mission India. Objective: The purpose of this study was to evaluate our experience with cardiac electrophysiologic studies (EPS) and RFA catheter of atrial fibrillation (AF). Materials and Methods: This was a retrospective study carried out in the Cardiac Electrophysiology Department of the Institute of Cardiovascular Diseases, Madras Medical Mission, India. All cases diagnosed to have AF following cardiac EPS between January 2010 and April 2014 was selected for the study. The records, which were obtained from the Cardiac Electrophysiology Clinical Research Office of Madras Medical Mission, were reviewed. Forty-nine cases were chosen for analysis, using SPSS statistical software version 15. Results: There were 49 patients, 23 males and 26 females. The mean age was 57.53 years. Commonly associated diseases were diabetes mellitus 8 (16.3%), hypertension 18 (36.7%), and coronary heart disease 14 (28.5%). The ventricular rate was rapid most cases (91.2%). AF was diagnosed as being paroxysmal in 40 (81.6%), persistent in 5 (10.2%), chronic in 3 (6.1%), and lone in 1 (2.0%). Ablation was carried out in 28 (57.1%), the success rate being 90% for pulmonary vein isolation, and 90.9% for atrioventricular node ablation. Complication rate was 2.04%. Conclusions: Treatment of AF by RFA is highly effective and safe.

    Nosocomial urinary tract infection (UTI) increases hospitalization, cost and morbidity. In this cohort study, we aimed to determine the incidence, risk factors, etiology and outcomes of UTIs in post-operative cardiac children. To this end, we studied all post-operative patients admitted to the Pediatric Cardiac Intensive Care Unit (PCICU) in 2012, and we divided the patients into two groups: the UTI (UTI group) and the non-UTI (control group). We compared both groups for multiple peri-operative risk factors. We included 413 children in this study. Of these, 29 (7%) had UTIs after cardiac surgery (UTI group), and 384 (93%) were free from UTIs (control group). All UTI cases were catheter-associated UTIs (CAUTIs). A total of 1578 urinary catheter days were assessed in this study, with a CAUTI density rate of 18 per 1000 catheter days. Multivariate logistic regression analysis demonstrated the following risk factors for CAUTI development: duration of urinary catheter placement (pcongenital abnormalities of kidney and urinary tract (CAKUT) (purinary catheter, the presence of CAKUT, and the presence of syndromes comprised the main risk factors for CAUTI. Gram-negative organisms were the main causes for CAUTI, and one-third of them found to be resistant in this single-center study. PMID:26829892

  16. The New York State cardiac registries: history, contributions, limitations, and lessons for future efforts to assess and publicly report healthcare outcomes.

    Hannan, Edward L; Cozzens, Kimberly; King, Spencer B; Walford, Gary; Shah, Nirav R


    In 1988, the New York State Health Commissioner was confronted with hospital-level data demonstrating very large, multiple-year, interhospital variations in short-term mortality and complications for cardiac surgery. The concern with the extent to which these differences were due to variations in patients' pre-surgical severity of illness versus hospitals' quality of care led to the development of clinical registries for cardiac surgery in 1989 and for percutaneous coronary interventions in 1992 in New York. In 1990, the Department of Health released hospitals' risk-adjusted cardiac surgery mortality rates for the first time, and shortly thereafter, similar data were released for hospitals and physicians for percutaneous coronary interventions, cardiac valve surgery, and pediatric cardiac surgery (only hospital data). This practice is still ongoing. The purpose of this communication is to relate the history of this initiative, including changes or purported changes that have occurred since the public release of cardiac data. These changes include decreases in risk-adjusted mortality, cessation of cardiac surgery in New York by low-volume and high-mortality surgeons, out-of-state referral or avoidance of cardiac surgery/angioplasty for high-risk patients, alteration of contracting choices by insurance companies, and modifications in market share of cardiac hospitals. Evidence related to these impacts is reviewed and critiqued. This communication also includes a summary of numerous studies that used New York's cardiac registries to examine a variety of policy issues regarding the choice and use of cardiac procedures, the comparative effectiveness of competing treatment options, and the examination of the relationship among processes, structures, and outcomes of cardiac care.

  19. CKD classification based on estimated GFR over three years and subsequent cardiac and mortality outcomes: a cohort study

    Salem Deeb N


    Full Text Available Abstract Background It is unknown whether defining chronic kidney disease (CKD based on one versus two estimated glomerular filtration rate (eGFR assessments changes the prognostic importance of reduced eGFR in a community-based population. Methods Participants in the Atherosclerosis Risk in Communities Study and the Cardiovascular Health Study were classified into 4 groups based on two eGFR assessments separated by 35.3 ± 2.5 months: sustained eGFR 2 (1 mL/sec per 1.73 m2; eGFR increase (change from below to above 60; eGFR decline (change from above to below 60; and eGFR persistently ≥60. Outcomes assessed in stratified multivariable Cox models included cardiac events and a composite of cardiac events, stroke, and mortality. Results There were 891 (4.9% participants with sustained eGFR 60. Participants with eGFR sustained Conclusion Individuals with persistently reduced eGFR are at highest risk of cardiovascular outcomes and mortality, while individuals with an eGFR 2 at any time are at intermediate risk. Use of even a single measurement of eGFR to classify CKD in a community population appears to have prognostic value.

    Swartz, Michael F; Angona, Ron; Smith, Karen; Kraenzlin, Franca; Stypula, Christine M; Joshi, Devang; Tchantchaleishvili, Vakhtang; Hicks, George L; Massey, H Todd


    Bi-ventricular (Bi-V) mechanical circulatory support is commonly used as a bridge to cardiac transplant. However, the optimal strategy is unknown. We examined the outcomes, as well as the costs in the use of Bi-V support as a bridge to cardiac transplant. From 2001 to 2014, three different Bi-V support strategies were utilized: 1) Para-corporeal ventricular assist device (PVAD-2001-2006), 2) Heartmate II left ventricular assist device in conjunction with a temporary CentriMag right ventricular assist device (HMII + CMAG-2006-2012), and the total artificial heart (TAH-2012-2014). Total costs were derived from the hospitalization at implant, and postimplant costs defined as equipment and re-hospitalizations before transplantation. Sixty-five (34 PVADs, 20 HMII + CMAG, and 11 TAHs) devices were used as a bridge for transplant. There were no differences in implant variables including age, INTERMACS score, or implant length of stay. Although the wait list mortality was not different between groups (PVAD-32%, HMII + CMAG-45%, TAH-54%; p = 0.3), the percentage of patients transplanted were highest in the PVAD group: (PVAD-55.8%, HMII + CMAG-30.0%, TAH-18.2%; p = 0.01). Total costs were not significantly different between groups (PVAD-$306,166 ± 247,839, HMII + CMAG-$278,958 ± 135,324, TAH-$321,387 ± 21,2477; p = 0.5). Despite variations in therapy, outcomes and costs for patients requiring Bi-V support as a bridge to cardiac transplant have remained constant. PMID:27258229

  1. Larger Centers Produce Better Outcomes in Pediatric Cardiac Surgery: Regionalization is a Superior Model - The Con Prospective.

    Danton, Mark H D


    Regionalization, in the context of congenital heart surgery, describes a process where smaller units close and patients are redistributed to larger centers. Proponents argue this will produce superior patient outcome based primarily on a volume-outcome effect. The potential disadvantage is that, as distance to center increases, access to service is compromised. In this article the volume-outcome effect is appraised and the effect of risk-stratification and threshold volumes explored. Access to service, and how certain congenital lesions and demographics might be disadvantaged, is reviewed. Alternative models are considered including collaborative programing and a standardizing approach of agreed parameters in personnel and infrastructure. Finally the influence of newer developments and quality metrics, including outcome databases, digital technologies and team-cognitive performance, needs to be factored in as the future unfolds. Ultimately, the design of a national congenital cardiac program should aspire to deliver care that is optimal, equitable and economic for the whole population. The solution lies in the distillation of competing variables cognizant of regional demographics and geography. PMID:27060038

    Skodova, Zuzana; Nagyova, Iveta; van Dijk, Jitse P.; Sudzinova, Adriana; Vargova, Helena; Rosenberger, Jaroslav; Middel, Berrie; Studencan, Martin; Reijneveld, Sijmen A.


    The aim of this article is to explore socioeconomic inequalities in the psychological characteristics (psychological well-being, perceived mental health status) and perceived quality of life among cardiac patients. A structured interview was conducted with 362 patients (32% women, mean age 56 +/- 7.3 years) referred for coronary angiography. The GHQ-28 was used to measure psychological well-being, the SF-36 for perceived mental health status. Income and education indicated socioeconomic posit...

    Vélez-Martínez, Mariella; Ayers, Colby; Mishkin, Joseph D; Bartolome, Sonja B; García, Christine K; Torres, Fernando; Drazner, Mark H; de Lemos, James A; Turer, Aslan T; Chin, Kelly M


    Previous studies have identified cardiac troponin I (cTnI) as an important marker in pulmonary hypertension (PH) prognosis. However, traditional assays are limited by poor sensitivity, even among patients at high risk. cTnI was measured in 255 PH patients using a new highly sensitive (hs) assay. Other measures included demographics, creatinine, 6-minute walk distance, hemodynamics, cardiac magnetic resonance imaging, and B-type natriuretic peptide level. The association between cTnI and survival was assessed using Kaplan-Meier analysis and Cox regression. cTnI was detectable with the hs assay in 95% of the patients with a median level of 6.9 pg/ml (IQR 2.7-12.6 pg/ml). Higher cTnI levels associated with higher levels of B-type natriuretic peptide, shorter 6-minute walk distance, and more severe hemodynamic and cardiac magnetic resonance imaging abnormalities. During a median follow-up of 3.5 years, 60 individuals died. Unadjusted event rates increased across higher cTnI quartiles (3, 5, 13, 17 events/100 person-years, respectively, p trend = 0.002). cTnI in the fourth (vs first) quartile remained associated with death in a final stepwise multivariable model that included clinical variables and hemodynamics (adjusted hazard ratio 5.3, 95% confidence interval 1.8-15.6). In conclusion, cTnI levels, detectable with a novel hs assay, identify patients with PH who have more severe hemodynamic and cardiac structural abnormalities and provide novel and independent prognostic information. This hs assay has the potential to detect more at-risk patients and improve current risk-stratification algorithms. PMID:23540547

  6. Early and long-term outcomes of pericardiotomy in the treatment of primary cardiac tamponade

    Tomaszewska, Iga; Stefaniak, Sebastian; Bartczak, Agnieszka; Jemielity, Marek


    Introduction Cardiac tamponade is a life-threatening clinical entity that requires emergent treatment. A variety of therapeutic methods have been applied. The purpose of this retrospective analysis was to study the efficacy of emergent surgical pericardiotomy in both the relief of cardiac tamponade and in the prevention of recurrence of pericardial effusion. Material and methods This study involved 90 consecutive patients (58 males and 32 females) with a mean age of 57.4 ± 14.1 years, who underwent emergent pericardiotomy in the years 2006 to 2011 due to symptomatic primary cardiac tamponade. At the end of the follow-up period all living subjects had control echocardiographic examination. Survival analysis was performed with the use of the Kaplan-Meier method. Results The mean duration time of surgery was 14.2 ± 4.5 minutes. All patients survived surgery but one died during in-hospital stay. During the post-discharge follow-up period (median 49 months) 32 patients died for any reason. One-year and four-year probability of survival was 0.68 ± 0.05 and 0.64 ± 0.05, respectively. Malignancy diagnosis was associated with significant negative impact on survival. One-year and four-year probability of survival was 0.56 ± 0.06 and 0.53 ± 0.06 for cancer patients while it was 0.93 ± 0.05 and 0.89 ± 0.06 for the others, respectively. In two cases, only cancer patients, re-intervention due to effusion recurrence was necessary. Conclusions Pericardiotomy, although invasive, is a safe method to relieve cardiac tamponade. It is also very efficient in the prevention of recurrence of pericardial effusion, even in cancer patients. PMID:26702272

    Acyl-CoA dehydrogenase family, member 9 (ACAD9) mutation is a frequent, usually fatal cause of early-onset cardiac hypertrophy and mitochondrial respiratory chain complex I deficiency in early childhood. We retrospectively studied a series of 20 unrelated children with cardiac hypertrophy and isolated complex I deficiency and identified compound heterozygosity for missense, splice site or frame shift ACAD9 variants in 8/20 patients (40%). Age at onset ranged from neonatal period to 9 years and 5/8 died in infancy. Heart transplantation was possible in 3/8. Two of them survived and one additional patient improved spontaneously. Importantly, the surviving patients later developed delayed-onset neurologic or muscular symptoms, namely cognitive impairment, seizures, muscle weakness and exercise intolerance. Other organ involvement included proximal tubulopathy, renal failure, secondary ovarian failure and optic atrophy. We conclude that ACAD9 mutation is the most frequent cause of cardiac hypertrophy and isolated complex I deficiency. Heart transplantation in children surviving neonatal period should be considered with caution, as delayed-onset muscle and brain involvement of various severity may occur, even if absent prior to transplantation.

  8. Maternal and neonatal outcomes in pregnant patients with cardiac diseases referred for labour in northwest Iran

    Objective: To evaluate maternal and neonatal mortality and morbidity rates in women with different types of significant heart diseases. Methods: The cross-sectional study was conducted at a tertiary heart care centre in Tabriz, Iran, and comprised 200 pregnant women between March 2007 and March 2012 who had different cardiac diseases and were admitted in labour wards first and then transferred to the heart center for child-bearing (vaginal delivery or caesarean section). They were categorised based on the underlying etiology into valvular heart disease, dilated cardiomyopathy, congenital heart disease and other etiologies. SPSS 18 was used for statistical analysis. Results: The mean age of the 200 subjects was 29.4+-4.28 years. Caesarean section was performed on 152 (76%) cases, while 48 (24%) underwent vaginal delivery. There were 216 neonates as 16 (8%) women had twins. Overall, 164 (75.9%) were female, and 52 (24.1%) male. Maternal and neonatal mortality rates were 4.0% (n=8) and 10% (n=22) respectively. Pregnant women with Congenital heart disease experienced more maternal (p<0.022) and neonatal (p<0.031) mortality rates than other cardiac diseases. Conclusion: Pregnant women with cardiac diseases are prone to higher maternal and neonatal mortality rates in northwest Iran. (author)

    Matti-Aleski eMosorin


    Full Text Available Objective: The aim of this study is to evaluate the role of coronary artery bypass grafting (CABG in patients with out-of-hospital cardiac arrest (OHCA.Methods: The immediate and 5-year outcome after CABG of a consecutive series of 48 patients who survived OHCA were compared with those of control patients having had a recent myocardial infarction without ventricular arrhythmias.Results: All OHCA patients were found to have suffered myocardial infarction-related cardiac arrest. The mean delay from OHCA to CABG was 10.3±13.0 days. Despite not statistically significant, the risk of 30-day postoperative mortality was higher among OHCA patients than control patients (6.3% vs. 0%, p=0.24, propensity score adjusted analysis: p=1.00. Cardioverter defibrillator was implanted in two patients who were alive 3.8 and 4.4 years after CABG, respectively. At 5-year the overall survival rate was 80.7% in OHCA patients and 84.5% in control patients (p=0.98, propensity score adjusted analysis: p=0.87, and survival freedom from fatal cardiac event was 86.1% in OHCA patients and 86.5% in control patients (p=0.61; propensity score adjusted analysis: p=0.90. Conclusions: Early and 5-year survival rates after CABG in OHCA patients are excellent even when cardioverter defibrillator is very selectively implanted. Such good early and intermediate results observed after CABG suggest a confident approach toward surgical revascularization also in this critically ill patient population.

  10. Assessment of cardiac outcome in pancreas kidney transplant recipients using 99mTc-MIBI myocardial perfusion scintigraphy

    Full text: Simultaneous pancreas-kidney transplantation (SPK) in diabetic patients (patients) 99mTc-MIBI myocardial perfusion scintigraphy (MPI) in predicting cardiac outcome post SPK. One hundred and forty patients underwent SPK at our institution over a 15-year period. Sixty-six subjects were excluded because of incomplete follow-up (n=54) or death from non-cardiac causes (n=12). Seventy-four patients (44 men, 30 women) with age 44.3+/-7.4 yrs (range: 31-62yrs) were followed for up to 14 yrs post SPK. The mean interval between SPK and MPI was 48.1+/-37.1 months (median: 37.5, range: 6-132 months). MPI was performed using a standard two-day protocol with Adenosine or Dipyridamole and a dual-head gamma camera using 900 configuration, attenuation and scatter correction and resolution recovery. Images were reported by at least one experienced observer using standard software. MPI were classified as normal (n=33), infarct (n=4), small (n=32) or large (n=2) areas of impaired coronary flow reserve (CFR) or a combination of infarct and impaired CFR (n=3). Cardiac events were considered if infarct, angina, death or coronary revascularisation occurred. Two patients underwent coronary artery bypass surgery five yrs post SPK (both two yrs post MPI) and one patient developed angina six yrs post SPK (three yrs post MPI). In these patients, MPI showed only small areas of impaired CFR. The negative and positive predictive values for MPI were 100 and 9%, respectively. In summary, MPI has excellent NPV post SPK. The PPV is poor, suggesting that myocardial perfusion defects correlate only weakly with overall atherosclerotic risk profile post SPK.

  13. Effects of nimodipine on cerebral blood flow and cerebrospinal fluid pressure after cardiac arrest: correlation with neurologic outcome.

    Forsman, M; Aarseth, H P; Nordby, H K; Skulberg, A; Steen, P A


    Fifty-one patients were included in a blind randomized study to evaluate whether the Ca-blocker nimodipine could influence cerebral blood flow (CBF) or cerebrospinal fluid pressure (CSFP) during the cerebral hypoperfusion period that follows resuscitation from cardiac arrest and to determine whether changes in CBF correlate with neurologic outcome. CBF measured 1 to 4 hours after arrest with the use of 133Xe intravenous was significantly greater with nimodipine than with placebo (27 +/- 3 versus 13 +/- 1 ml.100 g-1.min-1 at 3 hours), but with no significant difference at 24 hours. There was no clinical evidence of seriously increased CSFP in any patient in either group the first 48 hours. Mean arterial pressure was significantly lower (86 +/- 4 versus 101 +/- 4 mm Hg at 3 hours), and antiarrhythmic drugs were used significantly less frequently in the nimodipine group than in the placebo group. Twelve patients in each group eventually regained consciousness. There was no significant difference in neurologic status between the two groups at any point, and no positive correlation between CBF in the hypoperfusion period and neurologic outcome. PMID:2929976

  14. Impact of etiology on the outcomes in heart failure patients treated with cardiac resynchronization therapy: a meta-analysis.

    Yanmei Chen

    Full Text Available BACKGROUND: Cardiac resynchronization therapy (CRT has been extensively demonstrated to benefit heart failure patients, but the role of underlying heart failure etiology in the outcomes was not consistently proven. This meta-analysis aimed to determine whether efficacy and effectiveness of CRT is affected by underlying heart failure etiology. METHODS AND RESULTS: Searches of MEDLINE, EMBASE and Cochrane databases were conducted to identify RCTs and observational studies that reported clinical and functional outcomes of CRT in ischemic cardiomyopathy (ICM and non-ischemic cardiomyopathy (NICM patients. Efficacy of CRT was assessed in 7 randomized controlled trials (RCTs with 7072 patients and effectiveness of CRT was evaluated in 14 observational studies with 3463 patients In the pooled analysis of RCTs, we found that CRT decreased mortality or heart failure hospitalization by 29% in ICM patients (95% confidence interval [CI], 21% to 35%, and by 28% (95% CI, 18% to 37% in NICM patients. No significant difference was observed between the 2 etiology groups (P = 0.55. In the pooled analysis of observational studies, however, we found that ICM patients had a 54% greater risk for mortality or HF hospitalization than NICM patients (relative risk: 1.54; 95% CI: 1.30-1.83; P<0.001. Both RCTs and observational studies demonstrated that NICM patients had greater echocardiographic improvements in the left ventricular ejection fraction and end-systolic volume, as compared with ICM patients (both P<0.001. CONCLUSION: CRT might reduce mortality or heart failure hospitalization in both ICM and NICM patients similarly. The improvement of the left ventricular function and remodeling is greater in NICM patients.

  19. Effects of Obstructive Sleep Apnea on Cardiac Function and Clinical Outcomes in Chinese Patients with ST-Elevation Myocardial Infarction

    Baoxin Liu


    Full Text Available Aim. The objective of this study was to investigate the influence of OSA on cardiac function in Chinese patients with ST-elevation myocardial infarction (STEMI and determine the prognostic impact of OSA among these patients. Methods. In this retrospective study, 198 STEMI patients were enrolled. Doppler echocardiography was performed to detect the effect of OSA on cardiac function. Major adverse cardiac events (MACE and cardiac mortality were analyzed to determine whether OSA was a clinical prognostic factor; its prognostic impact was then assessed adjusting for other covariates. Results. The echocardiographic results showed that the myocardium of STEMI patients with OSA appeared to be more hypertrophic and with a poorer cardiac function compared with non-OSA STEMI patients. A Kaplan-Meier survival analysis revealed significantly higher cumulative incidence of MACE and cardiac mortality in the OSA group compared with that in the non-OSA group during a mean follow-up of 24 months. Multivariate Cox regression analysis revealed that OSA was an independent risk factor for MACE and cardiac mortality. Conclusion. These results indicate that the OSA is a powerful predictor of decreased survival and exerts negative prognostic impact on cardiac function in STEMI patients.

  20. Prolonged cardiac arrest and resuscitation by extracorporeal life support: favourable outcome without preceding anticoagulation in an experimental setting.

    Foerster, K; D'Inka, M; Beyersdorf, F; Benk, C; Nguyen-Thanh, T; Mader, I; Fritsch, B; Ihling, C; Mueller, K; Heilmann, C; Trummer, G


    State-of-the-art cardiopulmonary resuscitation (CPR) restores circulation with inconsistent blood-flow and pressure. Extracorporeal life support (ECLS) following CPR opens the opportunity for "controlled reperfusion". In animal experiments investigating CPR with ECLS, systemic anticoagulation before induced cardiac arrest is normal, but a major point of dispute, since preliminary heparinization in patients undergoing unwitnessed cardiac arrest is impossible. In this study, we investigated options for ECLS after an experimental 15 minutes normothermic cardiac arrest, without preceding anticoagulation, in pigs. Neurological recovery was assessed by a scoring system, electroencephalography and brain magnetic resonance imaging. Additionally, brain histology was performed on day seven after cardiac arrest. We demonstrated that preliminary heparin administration was not necessary for survival or neurological recovery in this setting. Heparin flushing of the cannulae seemed sufficient to avoid thrombus formation. These findings may ease the way to using ECLS in patients with sudden cardiac arrest. PMID:23827862

Octogenarians had an increased mortality (HR = 3.5, CI: 2...

  6. Impact of sirolimus-eluting stent fractures without early cardiac events on long-term clinical outcomes: A multislice computed tomography study

    Ito, Tsuyoshi [Toyohashi Heart Center, Oyama-cho, Toyohashi (Japan); Nagoya City University Graduate School of Medical Sciences, Department of Cardio-Renal Medicine and Hypertension, Nagoya (Japan); Kimura, Masashi; Ehara, Mariko; Terashima, Mitsuyasu; Nasu, Kenya; Kinoshita, Yoshihisa; Habara, Maoto; Tsuchikane, Etsuo; Suzuki, Takahiko [Toyohashi Heart Center, Oyama-cho, Toyohashi (Japan)


    This study sought to evaluate the impact of sirolimus-eluting stent (SES) fractures on long-term clinical outcomes using multislice computed tomography (MSCT). In this study, 528 patients undergoing 6- to 18-month follow-up 64-slice MSCT after SES implantation without early clinical events were followed clinically (the median follow-up interval was 4.6 years). A CT-detected stent fracture was defined as a complete gap with Hounsfield units (HU) <300 at the site of separation. The major adverse cardiac events (MACEs), including cardiac death, stent thrombosis, and target lesion revascularisation, were compared according to the presence of stent fracture. Stent fractures were observed in 39 patients (7.4 %). MACEs were more common in patients with CT-detected stent fractures than in those without (46 % vs. 7 %, p < 0.01). Univariate Cox regression analysis indicated a significant relationship between MACE and stent fracture [hazard ratio (HR) 7.65; p < 0.01], age (HR 1.03; p = 0.04), stent length (HR 1.03; p < 0.01), diabetes mellitus (HR 1.77; p = 0.04), and chronic total occlusion (HR 2.54; p = 0.01). In the multivariate model, stent fracture (HR 5.36; p < 0.01) and age (HR 1.03; p = 0.04) remained significant predictors of MACE. An SES fracture detected by MSCT without early clinical events was associated with long-term clinical adverse events. (orig.)

    Abstract Aims: Cardiac surgery involves myocardial ischemia/reperfusion (I/R) with potentially deleterious consequences. Macrophage migration inhibitory factor (MIF) is a stress-regulating chemokine-like cytokine that protects against I/R damage, but functional links with its homolog, d-dopachrome tautomerase (MIF-2), and the circulating soluble receptor CD74 (sCD74) are unknown. In this study, we investigate the role of MIF, MIF-2, sCD74, and MIF genotypes in patients scheduled for elective single or complex surgical procedures such as coronary artery bypass grafting or valve replacement. Results: MIF and MIF-2 levels significantly increased intraoperatively, whereas measured sCD74 decreased correspondingly. Circulating sCD74/MIF complexes were detectable in 50% of patients and enhanced MIF antioxidant activity. Intraoperative MIF levels were independently associated with a reduced risk for the development of atrial fibrillation (AF) (odds ratio 0.99 [0.98–1.00]; p=0.007). Circulating levels of MIF-2, but not MIF, were associated with an increased frequency of organ dysfunction and predicted the occurrence of AF (area under the curve [AUC]=0.663; p=0.041) and pneumonia (AUC=0.708; p=0.040). Patients with a high-expression MIF genotype exhibited a reduced incidence of organ dysfunction compared with patients with low-expression MIF genotypes (3 vs. 25; p=0.042). Innovation: The current study comprehensively highlights the kinetics and clinical relevance of MIF family proteins and the MIF genotype in cardiac surgery patients. Conclusion: Our findings suggest that increased MIF levels during cardiac surgery feature organ-protective properties during myocardial I/R, while the soluble MIF receptor, sCD74, may enhance MIF antioxidant activity. In contrast, high MIF-2 levels are predictive of the development of organ dysfunction. Importantly, we provide first evidence for a gene–phenotype relationship between variant MIF alleles and clinical outcome in cardiac

    Background Studies of cardiac disease among adult survivors of childhood cancer have generally relied upon self-reported or registry-based data. Objective Systematically assess cardiac outcomes among childhood cancer survivors Design Cross-sectional Setting St. Jude Children's Research Hospital Patients 1,853 adult survivors of childhood cancer, ≥18 years old, and ≥10 years from treatment with cardiotoxic therapy for childhood cancer. Measurements History/physical examination, fasting metabolic and lipid panels, echocardiogram, electrocardiogram (ECG), 6-minute walk test (6MWT) all collected at baseline evaluation. Results Half (52.3%) of the survivors were male, median age 8.0 years (range: 0-24) at cancer diagnosis, 31.0 years (18-60) at evaluation. Cardiomyopathy was present in 7.4% (newly identified at the time of evaluation in 4.7%), coronary artery disease (CAD) in 3.8% (newly identified in 2.2%), valvular regurgitation/stenosis in 28.0% (newly identified in 24.8%), and conduction/rhythm abnormalities in 4.6% (newly identified in 1.4%). Nearly all (99.7%) were asymptomatic. The prevalences of cardiac conditions increased with age at evaluation, ranging from 3-24% among those 30-39 years to 10-37% among those ≥40 years. On multivariable analysis, anthracycline exposure ≥250 mg/m2 increased the odds of cardiomyopathy (odds ratio [OR] 2.7, 95% CI 1.1-6.9) compared to anthracycline unexposed survivors. Radiation to the heart increased the odds of cardiomyopathy (OR 1.9 95% CI 1.1-3.7) compared to radiation unexposed survivors. Radiation >1500 cGy with any anthracycline exposure conferred the greatest odds for valve findings. Limitations 61% participation rate of survivors exposed to cardiotoxic therapies, which were limited to anthracyclines and cardiac-directed radiation. A comparison group and longitudinal assessments are not available. Conclusions Cardiovascular screening identified considerable subclinical disease among adult survivors of childhood

  9. Are There Benefits to a Fresh Whole Blood vs. Packed Red Blood Cell Cardiopulmonary Bypass Prime on Outcomes in Neonatal and Pediatric Cardiac Surgery?

    Valleley, Melinda S.; Buckley, Klayton W.; Hayes, Kylie M.; Fortuna, Randall R.; Geiss, Dale M.; Holt, David W.


    Abstract: Techniques for pediatric cardiac surgery requiring cardiopulmonary bypass (CPB) have significantly improved over the years. The use of fresh whole blood (FWB) and pre-bypass ultrafiltration (PBUF) has been suggested as means for improving perioperative and postoperative outcomes. It is the intent of this study to show that fresh whole blood along with PBUF will result in balanced CPB prime that can offer a reduction in blood product exposures and blood loss along with improving several measured postoperative outcomes. After institutional review board approval, a retrospective review was conducted on 100 patients to analyze the benefits of FWB and PBUF on outcomes in neonatal and pediatric cardiac surgery. Data analysis included preoperative and CPB data, perioperative inotrope and blood product exposure, and postoperative blood loss and blood product exposure measured for up to a 12-hour period in the intensive care unit (ICU). The three groups compared were FWB prime vs. packed red blood cell (PRBC) prime, <5 kg FWB prime vs. <5 kg PRBC prime, and 5+ kg FWB prime and 5+ kg PRBC prime. Cumulative blood product exposures for the FWB prime group found 62% received one blood exposure for the operative and postoperative period (p < .0001). The majority of patients who received a PRBC prime (64%) received three or more cumulative exposures (p < .0003). The <5 kg FWB group also received significantly less cumulative blood exposure, with 64% receiving just one exposure. Comparatively, 85% of the <5 kg PRBC patients received three or more blood product exposures perioperatively and postoperatively (p < .0001). Perioperative inotrope and postoperative blood loss did not differ among the groups. Outcomes for intraoperative death, intraoperative extubation, delayed sternal closure, and mediastinal reexploration were also not statistically different. The results of this study found that FWB leads to significantly less blood exposure, specifically in the <5-kg

  11. Cardiac tumours in children

    Parsons Jonathan M


    Full Text Available Abstract Cardiac tumours are benign or malignant neoplasms arising primarily in the inner lining, muscle layer, or the surrounding pericardium of the heart. They can be primary or metastatic. Primary cardiac tumours are rare in paediatric practice with a prevalence of 0.0017 to 0.28 in autopsy series. In contrast, the incidence of cardiac tumours during foetal life has been reported to be approximately 0.14%. The vast majority of primary cardiac tumours in children are benign, whilst approximately 10% are malignant. Secondary malignant tumours are 10–20 times more prevalent than primary malignant tumours. Rhabdomyoma is the most common cardiac tumour during foetal life and childhood. It accounts for more than 60% of all primary cardiac tumours. The frequency and type of cardiac tumours in adults differ from those in children with 75% being benign and 25% being malignant. Myxomas are the most common primary tumours in adults constituting 40% of benign tumours. Sarcomas make up 75% of malignant cardiac masses. Echocardiography, Computing Tomography (CT and Magnetic Resonance Imaging (MRI of the heart are the main non-invasive diagnostic tools. Cardiac catheterisation is seldom necessary. Tumour biopsy with histological assessment remains the gold standard for confirmation of the diagnosis. Surgical resection of primary cardiac tumours should be considered to relieve symptoms and mechanical obstruction to blood flow. The outcome of surgical resection in symptomatic, non-myxomatous benign cardiac tumours is favourable. Patients with primary cardiac malignancies may benefit from palliative surgery but this approach should not be recommended for patients with metastatic cardiac tumours. Surgery, chemotherapy and radiotherapy may prolong survival. The prognosis for malignant primary cardiac tumours is generally extremely poor.

    Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related morbidity and mortality. Both antibodies and bioactive lipids that have accumulated during storage of blood have been implicated in TRALI pathogenesis. In a single-center, nested, case-control study, patients were prospectively observed for onset of TRALI according to the consensus definition. Of 668 patients, 16 patients (2.4%) developed TRALI. Patient-related risk factors for onset of TRALI were age and time on the cardiopulmonary bypass. Transfusion-related risk factors were total amount of blood products (odds ratio [OR] = 1.2; 95% confidence interval [CI], 1.03-1.44), number of red blood cells stored more than 14 days (OR = 1.6; 95% CI, 1.04-2.37), total amount of plasma (OR = 1.2; 95% CI, 1.03-1.44), presence of antibodies in donor plasma (OR = 8.8; 95% CI, 1.8-44), and total amount of transfused bioactive lipids (OR = 1.0; 95% CI, 1.00-1.07). When adjusted for patient risk factors, only the presence of antibodies in the associated blood products remained a risk factor for TRALI (OR = 14.2; 95% CI, 1.5-132). In-hospital mortality of TRALI was 13% compared with 0% and 3% in transfused and nontransfused patients, respectively (P < .05). In conclusion, the incidence of TRALI is high in cardiac surgery patients and associated with adverse outcome. Our results suggest that cardiac surgery patients may benefit from exclusion of blood products containing HLA/HNA antibodies. PMID:21325598

    Kim, Bum Sung; Chun, Kwang Jin; Hwang, Jin kyung; Park, Seung-Jung; Park, Kyoung-Min; Kim, June Soo; On, Young Keun


    Abstract Objective: To evaluate predictors and long-term prognosis of atrial fibrillation (AF) following cardiac implantable electronic device (CIED) implantation in patients without history of AF. Methods: From May 1994 to April 2014, 1825 patients with CIED were enrolled in a retrospective, single-center registry. A total of 880 patients from the registry without prior documented AF history were included in the final analysis and were placed into either non-detected AF (NDAF) group or CIED-detected AF group according to development of AF over a follow-up period of 7 years. AF development was defined as any paroxysmal atrial tachyarrhythmia (atrial rate ≥ 180 beats/min) lasting at least 5 minutes according to CIED records. Results: Overall, 122 (13.8%) of the 880 patients experienced new development of AF during follow-up period. According to multivariate analysis, the independent predictors for development of AF were prior heart failure (hazard ratio [HR], 2.40; 95% confidence interval [CI], 1.50–3.85; P HR, 2.33; 95% CI, 1.62–3.55; P HR, 2.01; 95% CI, 1.23–3.30; P = 0.005). In CDAF group, the risk of heart failure readmission (adjusted HR, 3.79; 95% CI, 1.99–7.22; P HR, 5.33; 95% CI, 1.58–17.97; P = 0.007) was higher than in nondetected AF group. Conclusion: In patients with CIED, prior history of heart failure, sinus node dysfunction, and LA volume index ≥38.5 mL/m2 were independent predictors of new AF cases. Newly developed AF was significantly associated with increased risk of HF and stroke readmission, according to long-term follow up. PMID:27428213

  16. Serum MMP-8: a novel indicator of left ventricular remodeling and cardiac outcome in patients after acute myocardial infarction.

    Marie Fertin

    Full Text Available OBJECTIVE: Left ventricular (LV remodeling following myocardial infarction (MI is characterized by progressive alterations of structure and function, named LV remodeling. Although several risk factors such as infarct size have been identified, LV remodeling remains difficult to predict in clinical practice. Changes within the extracellular matrix, involving matrix metalloproteinases (MMPs and tissue inhibitors of metalloproteinases (TIMPs, are an integral part of left ventricular (LV remodeling after myocardial infarction (MI. We investigated the temporal profile of circulating MMPs and TIMPs and their relations with LV remodeling at 1 year and clinical outcome at 3 years in post-MI patients. METHODS: This prospective multicentre study included 246 patients with a first anterior MI. Serial echocardiographic studies were performed at hospital discharge, 3 months, and 1 year after MI, and analysed at a core laboratory. LV remodeling was defined as the percent change in LV end-diastolic volume (EDV from baseline to 1 year. Serum samples were obtained at hospital discharge, 1, 3, and 12 months. Multiplex technology was used for analysis of MMP-1, -2, -3, -8, -9, -13, and TIMP-1, -2, -3, -4 serum levels. RESULTS: Baseline levels of MMP-8 and MMP-9 were positively associated with changes in LVEDV (P = 0.01 and 0.02, respectively. When adjusted for major baseline characteristics, MMP-8 levels remained an independent predictor LV remodeling (P = 0.025. By univariate analysis, there were positive relations between cardiovascular death or hospitalization for heart failure during the 3-year follow-up and the baseline levels of MMP-2 (P = 0.03, MMP-8 (P = 0.002, and MMP-9 (P = 0.03. By multivariate analysis, MMP-8 was the only MMP remaining significantly associated with clinical outcome (P = 0.02. CONCLUSION: Baseline serum MMP-8 is a significant predictor of LV remodeling and cardiovascular outcome after MI and may help to improve

  18. Cardiac fusion and complex congenital cardiac defects in thoracopagus twins: diagnostic value of cardiac CT

    Goo, Hyun Woo [University of Ulsan College of Medicine, Asan Medical Center, Department of Radiology and Research Institute of Radiology, Seoul (Korea, Republic of); Park, Jeong-Jun [University of Ulsan College of Medicine, Asan Medical Center, Department of Pediatric Cardiac Surgery, Seoul (Korea, Republic of); Kim, Ellen Ai-Rhan [University of Ulsan College of Medicine, Asan Medical Center, Division of Neonatology, Department of Pediatrics, Seoul (Korea, Republic of); Won, Hye-Sung [University of Ulsan College of Medicine, Asan Medical Center, Department of Obstetrics and Gynecology, Seoul (Korea, Republic of)


    Most thoracopagus twins present with cardiac fusion and associated congenital cardiac defects, and assessment of this anatomy is of critical importance in determining patient care and outcome. Cardiac CT with electrocardiographic triggering provides an accurate and quick morphological assessment of both intracardiac and extracardiac structures in newborns, making it the best imaging modality to assess thoracopagus twins during the neonatal period. In this case report, we highlight the diagnostic value of cardiac CT in thoracopagus twins with an interatrial channel and complex congenital cardiac defects. (orig.)

  19. Earliest Bedside Assessment of Hemodynamic Parameters and Cardiac Biomarkers: Their Role as Predictors of Adverse Outcome in Patients with Septic Shock

    Sasko, Benjamin; Butz, Thomas; Prull, Magnus Wilhelm; Liebeton, Jeanette; Christ, Martin; Trappe, Hans-Joachim


    Background: Early assessment and aggressive hemodynamic treatment have been shown to increase the survival of patients in septic shock. Current and past sepsis guidelines recommend a resuscitation protocol including central venous pressure (CVP), mean arterial blood pressure (MAP), urine output and central venous oxygen saturation (ScvO2) for resuscitation within the first six hours. Currently, the established severity score systems like APACHE II score, SOFA score or SAPS II score predict the outcome of critically ill patients on the bases of variables obtained only after the first 24 hours. The present study aims to evaluate the risk of short-term mortality for patients with septic shock by the earliest possible assessment of hemodynamic parameters and cardiac biomarkers as well as their role for the prediction of the adverse outcome. Methods: 52 consecutive patients treated for septic shock in the intensive care unit of one centre (Marien Hospital Herne, Ruhr University Bochum, Germany) were prospectively enrolled in this study. Hemodynamic parameters (MAP, CVP, ScvO2, left ventricular ejection fraction, Hematocrit) and cardiac biomarkers (Troponin I) at the ICU admission were evaluated in regard to their influence on mortality. The primary endpoint was all-cause mortality within 28 days after the admission. Results: A total of 52 patients (31 male, 21 female) with a mean age of 71.4±8.5 years and a mean APACHE II score of 37.0±7.6 were enrolled in the study. 28 patients reached the primary endpoint (mortality 54%). Patients presenting with hypotension (MAP <65 mmHg) at ICU admission had significantly higher rates of 28-day mortality as compared with the group of patients without hypotension (28-day mortality rate 74 % vs. 32 %, p<0.01). Furthermore, the patients in the hypotension present group had significantly higher lactate concentration (p=0.002), higher serum creatinin (p=0.04), higher NTproBNP (p=0.03) and after the first 24 hours higher APACHE II

  20. Combining Amplitude Spectrum Area with Previous Shock Information Using Neural Networks Improves Prediction Performance of Defibrillation Outcome for Subsequent Shocks in Out-Of-Hospital Cardiac Arrest Patients.

    Mi He

    Full Text Available Quantitative ventricular fibrillation (VF waveform analysis is a potentially powerful tool to optimize defibrillation. However, whether combining VF features with additional attributes that related to the previous shock could enhance the prediction performance for subsequent shocks is still uncertain.A total of 528 defibrillation shocks from 199 patients experienced out-of-hospital cardiac arrest were analyzed in this study. VF waveform was quantified using amplitude spectrum area (AMSA from defibrillator's ECG recordings prior to each shock. Combinations of AMSA with previous shock index (PSI or/and change of AMSA (ΔAMSA between successive shocks were exercised through a training dataset including 255shocks from 99patientswith neural networks. Performance of the combination methods were compared with AMSA based single feature prediction by area under receiver operating characteristic curve(AUC, sensitivity, positive predictive value (PPV, negative predictive value (NPV and prediction accuracy (PA through a validation dataset that was consisted of 273 shocks from 100patients.A total of61 (61.0% patients required subsequent shocks (N = 173 in the validation dataset. Combining AMSA with PSI and ΔAMSA obtained highest AUC (0.904 vs. 0.819, p<0.001 among different combination approaches for subsequent shocks. Sensitivity (76.5% vs. 35.3%, p<0.001, NPV (90.2% vs. 76.9%, p = 0.007 and PA (86.1% vs. 74.0%, p = 0.005were greatly improved compared with AMSA based single feature prediction with a threshold of 90% specificity.In this retrospective study, combining AMSA with previous shock information using neural networks greatly improves prediction performance of defibrillation outcome for subsequent shocks.

  3. The secular trends in the incidence rate and outcomes of out-of-hospital cardiac arrest in Taiwan--a nationwide population-based study.

    Cheng-Yi Wang

    Full Text Available This study investigated the trends in incidence and mortality of out-of-hospital cardiac arrest (OHCA, as well as factors associated with OHCA outcomes in Taiwan.Our study included OHCA patients requiring cardiopulmonary resuscitation (CPR upon arrival at the hospital. We used national time-series data on annual OHCA incidence rates and mortality rates from 2000 to 2012, and individual demographic and clinical data for all OHCA patients requiring mechanical ventilation (MV care from March of 2010 to September of 2011. Analytic techniques included the time-series regression and the logistic regression.There were 117,787 OHCAs in total. The overall incidence rate during the 13 years was 51.1 per 100,000 persons, and the secular trend indicates a sharp increase in the early 2000s and a decrease afterwards. The trend in mortality was also curvilinear, revealing a substantial increase in the early 2000s, a subsequent steep decline and finally a modest increase. Both the 30-day and 180-day mortality rates had a long-term decreasing trend over the period (p<0.01. For both incidence and mortality rates, a significant second-order autoregressive effect emerged. Among OHCA patients with MV, 1-day, 30-day and 180-day mortality rates were 31.3%, 75.8%, and 86.0%, respectively. In this cohort, older age, the female gender, and a Charlson comorbidity index score ≥ 2 were associated with higher 180-day mortality; patients delivered to regional hospitals and those residing in non-metropolitan areas had higher death risk.Overall, both the 30-day and the 180-day mortality rates after OHCA had a long-term decreasing trend, while the 1-day mortality had no long-term decline. Among OHCA patients requiring MV, those delivered to regional hospitals and those residing in non-metropolitan areas tended to have higher mortality, suggesting a need for effort to further standardize and improve in-hospital care across hospitals and to advance pre-hospital care in non

  4. Cardiac rehabilitation in Germany.

    Karoff, Marthin; Held, Klaus; Bjarnason-Wehrens, Birna


    The purpose of this review is to give an overview of the rehabilitation measures provided for cardiac patients in Germany and to outline its legal basis and outcomes. In Germany the cardiac rehabilitation system is different from rehabilitation measures in other European countries. Cardiac rehabilitation in Germany since 1885 is based on specific laws and the regulations of insurance providers. Cardiac rehabilitation has predominantly been offered as an inpatient service, but has recently been complemented by outpatient services. A general agreement on the different indications for offering these two services has yet to be reached. Cardiac rehabilitation is mainly offered after an acute cardiac event and bypass surgery. It is also indicated in severe heart failure and special cases of percutaneous coronary intervention. Most patients are men (>65%) and the age at which events occur is increasing. The benefits obtained during the 3-4 weeks after an acute event, and confirmed in numerous studies, are often later lost under 'usual care' conditions. Many attempts have been made by rehabilitation institutions to improve this deficit by providing intensive aftercare. One instrument set up to achieve this is the nationwide institution currently comprising more than 6000 heart groups with approximately 120000 outpatients. After coronary artery bypass grafting or acute coronary syndrome cardiac rehabilitation can usually be started within 10 days. The multidisciplinary rehabilitation team consists of cardiologists, psychologists, exercise therapists, social workers, nutritionists and nurses. The positive effects of cardiac rehabilitation are also important economically, for example, for the improvement of secondary prevention and vocational integration. PMID:17301623

  7. Contemporary Breast Radiotherapy and Cardiac Toxicity.

    Yeboa, Debra Nana; Evans, Suzanne Buckley


    Long-term cardiac effects are an important component of survivorship after breast radiotherapy. The pathophysiology of cardiotoxicity, history of breast radiotherapy, current methods of cardiac avoidance, modern outcomes, context of historical outcomes, quantifying cardiac effects, and future directions are reviewed in this article. Radiation-induced oxidative stress induces proinflammatory cytokines and is a process that potentiates late effects of fibrosis and intimal proliferation in endothelial vasculature. Breast radiation therapy has changed substantially in recent decades. Several modern technologies exist to improve cardiac avoidance such as deep inspiration breath hold, gating, accelerated partial breast irradiation, and use of modern 3-dimensional planning. Modern outcomes may vary notably from historical long-term cardiac outcomes given the differences in cardiac dose with modern techniques. Methods of quantifying radiation-related cardiotoxicity that correlate with future cardiac risks are needed with current data exploring techniques such as measuring computed tomography coronary artery calcium score, single-photon emission computed tomography imaging, and biomarkers. Placing historical data, dosimetric correlations, and relative cardiac risk in context are key when weighing the benefits of radiotherapy in breast cancer control and survival. Estimating present day cardiac risk in the modern treatment era includes challenges in length of follow-up and the use of confounding cardiotoxic agents such as evolving systemic chemotherapy and targeted therapies. Future directions in both multidisciplinary management and advancing technology in radiation oncology may provide further improvements in patient risk reduction and breast cancer survivorship.

  11. Vitamin D deficiency plays an important role in cardiac disease and affects patient outcome: Still a myth or a fact that needs exploration?

    Fanari, Zaher; Hammami, Sumaya; Hammami, Muhammad Baraa; Hammami, Safa; Abdellatif, Abdul


    There is increasing evidence that a low vitamin D status may be an important and hitherto neglected factor of cardiovascular disease. This review is an overview of the current body of literature, and presents evidence of the mechanisms through which vitamin D deficiency affects the cardiovascular system in general and the heart in particular. Available data indicate that the majority of congestive heart failure patients have 25-hydroxyvitamin D deficiency. Furthermore, the low serum 25-hydroxyvitamin D level has a higher impact on hypertension, coronary artery disease an on the occurrence of relevant cardiac events. A serum 25-hydroxyvitamin D level below 75 nmol/l (30 ng/l) is generally regarded as vitamin D insufficiency in both adults and children, while a level below 50 nmol/l (20 ng/l) is considered deficiency. Levels below 50 nmol/l (20 ng/l) are linked independently to cardiovascular morbidity and mortality. PMID:26557744

    Ivanović-Krstić Branislava A.


    Full Text Available Cardiac hydatid disease is rare. We report on an uncommon hydatid cyst localized in the right ventricular wall, right atrial wall tricuspid valve left atrium and pericard. A 33-year-old woman was treated for cough, fever and chest pain. Cardiac echocardiograpic examination revealed a round tumor (5.8 x 4 cm in the right ventricular free wall and two smaller cysts behind that tumor. There were cysts in right atrial wall and tricuspidal valve as well. Serologic tests for hydatidosis were positive. Computed tomography finding was consistent with diagnosis of hydatid cyst in lungs and right hylar part. Surgical treatment was rejected due to great risk of cardiac perforation. Medical treatment with albendazole was unsuccessful and the patient died due to systemic hydatid involvement of the lungs, liver and central nervous system.

RESULTS: In the pre-implantation Holter recording, ectopic beats accounted for a mean 3.2 ± 5.5% of...

  2. Cardiac manifestations in systemic sclerosis

    Sevdalina; Lambova


    Primary cardiac involvement, which develops as a direct consequence of systemic sclerosis(SSc), may manifest as myocardial damage, fibrosis of the conduction system, pericardial and, less frequently, as valvular disease. In addition, cardiac complications in SSc may develop as a secondary phenomenon due to pulmonary arterial hypertension and kidney pathology. The prevalence of primary cardiac involvement in SSc is variable and difficult to determine because of the diversity of cardiac manifestations, the presence of subclinical periods, the type of diagnostic tools applied, and the diversity of patient populations. When clinically manifested, cardiac involvement is thought to be an important prognostic factor. Profound microvascular disease is a pathognomonic feature of SSc, as both vasospasm and structural alterations are present. Such alterations are thought to predict macrovascular atherosclerosis over time. There are contradictory reports regarding the prevalence of atherosclerosis in SSc. According to some authors, the prevalence of atherosclerosis of the large epicardial coronary arteries is similar to that of the general population, in contrast with other rheumatic diseases such as rheumatoid arthritis and systemic lupus erythematosus. However, the level of inflammation in SSc is inferior. Thus, the atherosclerotic process may not be as aggressive and not easily detectable in smaller studies. Echocardiography(especially tissue Doppler imaging), single-photon emission computed tomography, magnetic resonance imaging and cardiac computed tomography are sensitive techniques for earlier detection of both structural and functional scleroderma-related cardiac pathologies. Screening for subclinical cardiac involvement via modern, sensitive tools provides an opportunity for early diagnosis and treatment, which is of crucial importance for a positive outcome.

  3. Troponin not just a simple cardiac marker: prognostic significance of cardiac troponin

    Benny Mulyanto Setiadi; LEI Han; CHANG Jing


    Objective The object of this study was to review the role of cardiac troponin as a prognostic factor in acute coronary syndrome patients of varying circumstances.Data sources The data used in this review were obtained mainly from the studies of cardiac troponin reported in pubmed from 1981 to 2006.Study selection Relevant articles on studies of cardiac troponin were selected.Results Elevated cardiac troponin in patients with ST elevation and non ST elevation myocardial infarction was associated with adverse outcomes, including a higher incidence of congestive heart failure, shock, and death. Patients with elevated cardiac troponin value seemed to benefit more from invasive strategies including a percutaneous coronary intervention and bypass surgery, but elevated cardiac troponin was also correlated with adverse outcomes, including a higher degree of failure, shock, and mortality in patients undergoing percutaneous coronary intervention; a higher degree of perioperative myocardial infarction, low cardiac output syndrome, cardiopulmonary resuscitation, and new-onset ventricular arrhythmia in patients undergoing bypass surgery were also observed. Elevated troponin after a percutaneous coronary intervention seemed to be associated with short-term adverse outcomes rather than long-term adverse outcomes, unless the elevation of the troponin post percutaneous coronary intervention was quite high (about 5 times above normal). On the contrary, elevated cardiac troponin after bypass surgery was more confusing to analyze since it happened in almost all patients. Furthermore, differences in cutoff values and time measurements in some studies add more confusion; thus, further research is warranted.Conclusions The prognostic value of cardiac troponin is demonstrated in almost all acute coronary syndrome patients. In addition to its high sensitivity and specificity, the prognostic value of cardiac troponin is another reason to make it the "golden cardiac marker' of this time.

  6. Fetal cardiac interventions: clinical and experimental research.

    Yuan, Shi-Min; Humuruola, Gulimila


    Fetal cardiac interventions for congenital heart diseases may alleviate heart dysfunction, prevent them evolving into hypoplastic left heart syndrome, achieve biventricular outcome and improve fetal survival. Candidates for clinical fetal cardiac interventions are now restricted to cases of critical aortic valve stenosis with evolving hypoplastic left heart syndrome, pulmonary atresia with an intact ventricular septum and evolving hypoplastic right heart syndrome, and hypoplastic left heart syndrome with an intact or highly restrictive atrial septum as well as fetal heart block. The therapeutic options are advocated as prenatal aortic valvuloplasty, pulmonary valvuloplasty, creation of interatrial communication and fetal cardiac pacing. Experimental research on fetal cardiac intervention involves technical modifications of catheter-based cardiac clinical interventions and open fetal cardiac bypass that cannot be applied in human fetuses for the time being. Clinical fetal cardiac interventions are plausible for midgestation fetuses with the above-mentioned congenital heart defects. The technical success, biventricular outcome and fetal survival are continuously being improved in the conditions of the sophisticated multidisciplinary team, equipment, techniques and postnatal care. Experimental research is laying the foundations and may open new fields for catheter-based clinical techniques. In the present article, the clinical therapeutic options and experimental fetal cardiac interventions are described. PMID:27279868

  7. MRI in cardiac sarcoidosis and amyloidosis

    Sarcoidosis and amyloidosis are both multisystem disorders, which may involve the heart; however, isolated cardiac disease is rare. Diagnosis of cardiac sarcoidosis and amyloidosis is crucial because the patient prognosis is dependent on cardiac involvement and early treatment. Echocardiography is the first line imaging modality in the diagnostic work-up of both diseases, possibly giving hints towards the correct diagnosis. Besides myocardial biopsy and radionuclide studies cardiac magnetic resonance imaging (MRI) is routinely performed in patients suspect of having infiltrative cardiomyopathy. The T1 mapping procedure is currently being evaluated as a new technique for detection and quantification of global myocardial enhancement, as seen in cardiac amyloidosis. Sensitivities and specificities for detection of cardiac sarcoidosis and amyloidosis can be significantly improved by MRI, especially with late gadolinium enhancement (LGE) imaging. In cardiac sarcoidosis the use of LGE is outcome-related while in amyloidosis analysis of T1-mapping may be of prognostic value. If cardiac involvement in sarcoidosis or amyloidosis is suspected cardiac MRI including LGE should be performed for establishing the diagnosis. (orig.)

  9. Donation after cardiac death in abdominal organ transplantation.

    Reich, David J; Guy, Stephen R


    This article reviews the field of donation after cardiac death, focusing on the history, ethicolegal issues, clinical outcomes, best practices, operative techniques, and emerging strategies to optimize utilization of this resource. Donation after cardiac death is one effective way to decrease the organ shortage and has contributed the largest recent increase in abdominal organ allografts. Currently, donation after cardiac death organs confer an increased risk of ischemic cholangiopathy after liver transplant and of delayed graft function after kidney transplant. As this field matures, risk factors for donation after cardiac death organ transplant will be further identified and clinical outcomes will improve as a result of protocol standardization and ongoing research.

    Heart failure (HF) frequently is the unfavorable outcome of pathological heart hypertrophy. In contrast to physiological cardiac hypertrophy, which occurs in response to exercise and leads to full adaptation of contractility to the increased wall stress, pathological hypertrophy occurs in response to volume or pressure overload, ultimately leading to contractile dysfunction and HF. Because cardiac hypertrophy impairs the relationship between ATP demand and production, mitochondrial bioenerget...

    Rao, Christopher; Patel, Vanash; Ibrahim, Michael; Ahmed, Kamran; Wong, Kathie A; Darzi, Ara; von Segesser, Ludwig K; Athanasiou, Thanos


    Despite the efficacy of cardiac surgery, less invasive interventions with more uncertain long-term outcomes are increasingly challenging surgery as first-line treatment for several congenital, degenerative and ischemic cardiac diseases. The specialty must evolve if it is to ensure its future relevance. More importantly, it must evolve to ensure that future patients have access to treatments with proven long-term effectiveness. This cannot be achieved without dynamic leadership; however, our contention is that this is not enough. The demands of a modern surgical career and the importance of the task at hand are such that the serendipitous emergence of traditional charismatic leadership cannot be relied upon to deliver necessary change. We advocate systematic analysis and strategic leadership at a local, national and international level in four key areas: Clinical Care, Research, Education and Training, and Stakeholder Engagement. While we anticipate that exceptional individuals will continue to shape the future of our specialty, the creation of robust structures to deliver collective leadership in these key areas is of paramount importance.

  15. Cardiac biomarkers in neonatal hypoxic ischaemia.

    Sweetman, D


    Following a perinatal hypoxic-ischaemic insult, term infants commonly develop cardiovascular dysfunction. Troponin-T, troponin-I and brain natriuretic peptide are sensitive indicators of myocardial compromise. The long-term effects of cardiovascular dysfunction on neurodevelopmental outcome following perinatal hypoxic ischaemia remain controversial. Follow-up studies are warranted to ensure optimal cardiac function in adulthood. CONCLUSION: Cardiac biomarkers may improve the diagnosis of myocardial injury, help guide management, estimate mortality risk and may also aid in longterm neurodevelopmental outcome prediction following neonatal hypoxic-ischaemia.

  17. External cardiac compression may be harmful in some scenarios of pulseless electrical activity.

    Hogan, T S


    Pulseless electrical activity occurs when organised or semi-organised electrical activity of the heart persists but the product of systemic vascular resistance and the increase in systemic arterial flow generated by the ejection of the left venticular stroke volume is not sufficient to produce a clinically detectable pulse. Pulseless electrical activity encompasses a very heterogeneous variety of severe circulatory shock states ranging in severity from pseudo-cardiac arrest to effective cardiac arrest. Outcomes of cardiopulmonary resuscitation for pulseless electrical activity are generally poor. Impairment of cardiac filling is the limiting factor to cardiac output in many scenarios of pulseless electrical activity, including extreme vasodilatory shock states. There is no evidence that external cardiac compression can increase cardiac output when impaired cardiac filling is the limiting factor to cardiac output. If impaired cardiac filling is the limiting factor to cardiac output and the heart is effectively ejecting all the blood returning to it, then external cardiac compression can only increase cardiac output if it increases venous return and cardiac filling. Repeated cardiac compression asynchronous with the patient\\'s cardiac cycle and raised mean intrathoracic pressure due to chest compression can be expected to reduce rather than to increase cardiac filling and therefore to reduce rather than to increase cardiac output in such circumstances. The hypothesis is proposed that the performance of external cardiac compression will have zero or negative effect on cardiac output in pulseless electrical activity when impaired cardiac filling is the limiting factor to cardiac output. External cardiac compression may be both directly and indirectly harmful to significant sub-groups of patients with pulseless electrical activity. We have neither evidence nor theory to provide comfort that external cardiac compression is not harmful in many scenarios of pulseless

  18. Cardiac perception and cardiac control. A review.

    Carroll, D


    The evidence regarding specific cardiac perception and discrimination, and its relationship to voluntary cardiac control, is critically reviewed. Studies are considered in three sections, depending on the method used to assess cardiac perception: questionnaire assessment, discrimination procedures, and heartbeat tracking. The heartbeat tracking procedure would appear to suffer least from interpretative difficulties. Recommendations are made regarding the style of analysis used to assess heartbeat perception in such tracking tasks. PMID:348240

    Duncan J Campbell


    Full Text Available Duncan J CampbellSt. Vincent’s Institute of Medical Research and the Department of Medicine, University of Melbourne, St. Vincent’s Hospital, Fitzroy, Victoria, AustraliaBackground: Angiotensin-converting enzyme inhibitors (ACEI have a well-established role in the prevention of cardiovascular events in hypertension, left ventricular dysfunction, and heart failure. More recently, ACEI have been shown to prevent cardiovascular events in individuals with increased cardiovascular risk, where hypertension, left ventricular dysfunction, or heart failure was not the primary indication for ACEI therapy.Objective: To review studies of the effects of the ACEI perindopril on cardiovascular events.Method: The EUROPA (European Trial on Reduction of Cardiac Events with Perindopril in Patients with Stable Coronary Artery Disease Study, PROGRESS (Perindopril Protection Against Recurrent Stroke Study, and ASCOT-BPLA (Anglo-Scandinavian Cardiac Outcomes Trial – Blood Pressure Lowering Arm trials are reviewed.Results: Perindopril alone reduced cardiovascular events in subjects with stable coronary heart disease. Perindopril in combination with indapamide reduced cardiovascular events in subjects with cerebrovascular disease. Perindopril in combination with amlodipine reduced cardiovascular events in subjects with hypertension.Conclusion: Perindopril reduced cardiovascular events. The reduction of cardiovascular events by perindopril was in large part associated with reduction of blood pressure, and greater reduction in cardiovascular events was associated with greater reduction of blood pressure. Perindopril may need to be combined with other antihypertensive agents to maximize reduction of cardiovascular events.Keywords: Angiotensin-converting enzyme inhibitor, hypertension, coronary heart disease, stroke, myocardial infarction, heart failure

  7. Reduced Right Ventricular Function Predicts Long-Term Cardiac Re-Hospitalization after Cardiac Surgery.

    Leela K Lella

    Full Text Available The significance of right ventricular ejection fraction (RVEF, independent of left ventricular ejection fraction (LVEF, following isolated coronary artery bypass grafting (CABG and valve procedures remains unknown. The aim of this study is to examine the significance of abnormal RVEF by cardiac magnetic resonance (CMR, independent of LVEF in predicting outcomes of patients undergoing isolated CABG and valve surgery.From 2007 to 2009, 109 consecutive patients (mean age, 66 years; 38% female were referred for pre-operative CMR. Abnormal RVEF and LVEF were considered 30 days outcomes included, cardiac re-hospitalization, worsening congestive heart failure and mortality. Mean clinical follow up was 14 months.Forty-eight patients had reduced RVEF (mean 25% and 61 patients had normal RVEF (mean 50% (p<0.001. Fifty-four patients had reduced LVEF (mean 30% and 55 patients had normal LVEF (mean 59% (p<0.001. Patients with reduced RVEF had a higher incidence of long-term cardiac re-hospitalization vs. patients with normal RVEF (31% vs.13%, p<0.05. Abnormal RVEF was a predictor for long-term cardiac re-hospitalization (HR 3.01 [CI 1.5-7.9], p<0.03. Reduced LVEF did not influence long-term cardiac re-hospitalization.Abnormal RVEF is a stronger predictor for long-term cardiac re-hospitalization than abnormal LVEF in patients undergoing isolated CABG and valve procedures.

  8. Cardiac MRI in restrictive cardiomyopathy

    Restrictive cardiomyopathy (RCM) is a specific group of heart muscle disorders characterized by inadequate ventricular relaxation during diastole. This leads to diastolic dysfunction with relative preservation of systolic function. Although short axis systolic function is usually preserved in RCM, the long axis systolic function may be severely impaired. Confirmation of diagnosis and information regarding aetiology, extent of myocardial damage, and response to treatment requires imaging. Importantly, differentiation from constrictive pericarditis (CCP) is needed, as only the latter is managed surgically. Echocardiography is the initial cardiac imaging technique but cannot reliably suggest a tissue diagnosis; although recent advances, especially tissue Doppler imaging and spectral tracking, have improved its ability to differentiate RCM from CCP. Cardiac catheterization is the reference standard, but is invasive, two-dimensional, and does not aid myocardial characterization. Cardiac magnetic resonance (CMR) is a versatile technique providing anatomical, morphological and functional information. In recent years, it has been shown to provide important information regarding disease mechanisms, and also been found useful to guide treatment, assess its outcome and predict patient prognosis. This review describes the CMR features of RCM, appearances in various diseases, its overall role in patient management, and how it compares with other imaging techniques.

  10. Gastrointestinal complications and cardiac surgery.

    Allen, Sara J


    Gastrointestinal (GI) complications are an uncommon but potentially devastating complication of cardiac surgery. The reported incidence varies between .3% and 5.5% with an associated mortality of .3-87%. A wide range of GI complications are reported with bleeding, mesenteric ischemia, pancreatitis, cholecystitis, and ileus the most common. Ischemia is thought to be the main cause of GI complications with hypoperfusion during cardiac surgery as well as systemic inflammation, hypothermia, drug therapy, and mechanical factors contributing. Several nonischemic mechanisms may contribute to GI complications, including bacterial translocation, adverse drug reactions, and iatrogenic organ injury. Risk factors for GI complications are advanced age (>70 years), reoperation or emergency surgery, comorbidities (renal disease, respiratory disease, peripheral vascular disease, diabetes mellitus, cardiac failure), perioperative use of an intra-aortic balloon pump or inotrope therapy, prolonged surgery or cardiopulmonary bypass, and postoperative complications. Multiple strategies to reduce the incidence of GI complications exist, including risk stratification scores, targeted inotrope and fluid therapy, drug therapies, and modification of cardiopulmonary bypass. Currently, no single therapy has consistently proven efficacy in reducing GI complications. Timely diagnosis and treatment, while tailored to the specific complication and patient, is essential for optimal management and outcomes in this challenging patient population. PMID:25208431

  11. Stimulating endogenous cardiac regeneration

    Amanda eFinan


    Full Text Available The healthy adult heart has a low turnover of cardiac myocytes. The renewal capacity, however, is augmented after cardiac injury. Participants in cardiac regeneration include cardiac myocytes themselves, cardiac progenitor cells, and peripheral stem cells, particularly from the bone marrow compartment. Cardiac progenitor cells and bone marrow stem cells are augmented after cardiac injury, migrate to the myocardium, and support regeneration. Depletion studies of these populations have demonstrated their necessary role in cardiac repair. However, the potential of these cells to completely regenerate the heart is limited. Efforts are now being focused on ways to augment these natural pathways to improve cardiac healing, primarily after ischemic injury but in other cardiac pathologies as well. Cell and gene therapy or pharmacological interventions are proposed mechanisms. Cell therapy has demonstrated modest results and has passed into clinical trials. However, the beneficial effects of cell therapy have primarily been their ability to produce paracrine effects on the cardiac tissue and recruit endogenous stem cell populations as opposed to direct cardiac regeneration. Gene therapy efforts have focused on prolonging or reactivating natural signaling pathways. Positive results have been demonstrated to activate the endogenous stem cell populations and are currently being tested in clinical trials. A potential new avenue may be to refine pharmacological treatments that are currently in place in the clinic. Evidence is mounting that drugs such as statins or beta blockers may alter endogenous stem cell activity. Understanding the effects of these drugs on stem cell repair while keeping in mind their primary function may strike a balance in myocardial healing. To maximize endogenous cardiac regeneration,a combination of these approaches couldameliorate the overall repair process to incorporate the participation ofmultiple cell players.

  12. Preoperative cardiac risk management

    Vidaković Radosav; Poldermans Don; Nešković Aleksandar N.


    Approximately 100 million people undergo noncardiac surgery annually worldwide. It is estimated that around 3% of patients undergoing noncardiac surgery experience a major adverse cardiac event. Although cardiac events, like myocardial infarction, are major cause of perioperative morbidity or mortality, its true incidence is difficult to assess. The risk of perioperative cardiac complications depends mainly on two conditions: 1) identified risk factors, and 2) the type of the surgical p...

  14. Lipidsenker bei Hypertonie - Was besagt die Evidenz?

    Marte T


    Full Text Available Die Koexistenz von Risikofaktoren für atherosklerotische Prozesse, wie Hypertonie und Hypercholesterinämie, hat einen multiplikativen Effekt auf das Risiko kardiovaskulärer Ereignisse. Bislang wurden relativ wenige spezifische Daten zur Frage der Lipidintervention bei Hypertoniepatienten veröffentlicht. Post-hoc-Subgruppenanalysen der großen randomisierten kontrollierten Studien mit Statinen in der Primär- und Sekundärprävention lassen schließen, daß der relative kardiovaskuläre Benefit einer lipidsenkenden Behandlung bei normotensiven und hypertensiven Patientenpopulationen ähnlich ist. Dem Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT-LLT war es nicht möglich, einen Einfluß einer Statintherapie auf die Gesamtmortalität einer hypertensiven Kohorte zu zeigen. Die schlechte Compliance im Statin-Arm und eine hohe Rate an Statin-Einnahme in der "Kontrollgruppe" waren für dieses negative Ergebnis verantwortlich. Das Anglo-Scandinavian Cardiac Outcomes Trial – Lipid Lowering Arm (ASCOT-LLA untersuchte den Effekt der cholesterinreduzierenden Therapie in der Prävention atherosklerotischer Ereignisse bei Hypertonikern mit Gesamtcholesterinkonzentrationen von 250 mg/dl. Hier war ein Benefit ersichtlich, die absolute Risikoreduktion für diese Patientenpopulation war jedoch gering. Bezüglich der Frage, ob Antihypertensiva einen klinisch signifikanten Effekt auf die Blutfette haben, sind einige Studien durchgeführt worden. Die verfügbaren Daten zeigen aber nur einen marginalen Effekt. Zusammengefaßt sollte die Statintherapie bei gleichzeitig vorhandener Hypertonie vornehmlich in der Sekundärprävention ein integraler Bestandteil der Behandlung sein. In der Primärprävention hingegen sollte die Entscheidung bezüglich Statintherapie vom individuellen Gesamtrisiko abhängig gemacht werden.

  15. Emergency Neurological Life Support: Resuscitation Following Cardiac Arrest.

    Rittenberger, Jon C; Friess, Stuart; Polderman, Kees H


    Cardiac arrest is the most common cause of death in North America. Neurocritical care interventions, including targeted temperature management (TTM), have significantly improved neurological outcomes in patients successfully resuscitated from cardiac arrest. Therefore, resuscitation following cardiac arrest was chosen as an emergency neurological life support protocol. Patients remaining comatose following resuscitation from cardiac arrest should be considered for TTM. This protocol will review induction, maintenance, and re-warming phases of TTM, along with management of TTM side effects. Aggressive shivering suppression is necessary with this treatment to ensure the maintenance of a target temperature. Ancillary testing, including electrocardiography, computed tomography and/or magnetic resonance imaging of the brain, continuous electroencephalography monitoring, and correction of electrolyte, blood gas, and hematocrit changes, are also necessary to optimize outcomes.

  16. Recent advances in the diagnosis and management of cardiac amyloidosis.

    Sher, Taimur; Gertz, Morie A


    The heart is commonly involved in various forms of amyloidosis and cardiomyopathy is a major cause of morbidity and mortality in these patients. Diagnosis of cardiac amyloidosis is often delayed due to nonspecific presenting symptoms and failure to recognize early signs of amyloid heart disease on routine cardiac imaging. Treatment of cardiac amyloidosis depends upon the type of amyloid protein. Systemic chemotherapy with or without stem cell transplantation is used to treat immunoglobulin-related amyloidosis and liver transplantation is used for familial transthyretin amyloidosis in select patients. Clinical trials with siRNA for the treatment of transthyretin amyloid cardiomyopathies and amyloid protein stabilizers are ongoing. Prognosis depends on the type of amyloid protein with poorer outcomes noted in immunoglobulin light-chain amyloidosis. Supportive care forms the cornerstone of management and advancements in cardiac imaging and proteomics are expected to positively impact our ability to diagnose, prognosticate and treat cardiac amyloidosis.

  17. Infected Cardiac Myxoma: an Updated Review

    Shi-Min Yuan


    Full Text Available ABSTRACT OBJECTIVE: This study aims to present an updated clinical picture of the infected cardiac myxoma. Revankar & Clark made a systematic review of infected cardiac myxoma based on the literature before 1998. Since then, there has not been any updated information describing its recent changing trends. METHODS: A comprehensive literature search of infected cardiac myxoma was conducted on MEDLINE, Highwire Press and Google between 1998 and 2014. RESULTS: In comparison with Revankar & Clark's series, the present series disclosed a significantly decreased overall mortality. It is believed that refinement of the prompt diagnosis and timely management (use of sensitive antibiotics and surgical resection of the infected myxoma have resulted in better outcomes of such patients. CONCLUSION: The present series of infected cardiac myxoma illustrated some aggravated clinical manifestations (relative more occasions of high-grade fever, multiple embolic events and the presence of refractory microorganisms, which should draw enough attention to careful diagnosis and treatment. In general, the prognosis of infected cardiac myxoma is relatively benign and the long-term survival is always promising.

  18. Blunt cardiac rupture.

    Martin, T D; Flynn, T C; Rowlands, B J; Ward, R E; Fischer, R P


    Blunt injury to the heart ranges from contusion to disruption. This report comprises 14 patients seen during a 6-year period with cardiac rupture secondary to blunt trauma. Eight patients were injured in automobile accidents, two patients were injured in auto-pedestrian accidents, two were kicked in the chest by ungulates, and two sustained falls. Cardiac tamponade was suspected in ten patients. Five patients presented with prehospital cardiac arrest or arrested shortly after arrival. All underwent emergency department thoracotomy without survival. Two patients expired in the operating room during attempted cardiac repair; both had significant extracardiac injury. Seven patients survived, three had right atrial injuries, three had right ventricular injuries, and one had a left atrial injury. Cardiopulmonary bypass was not required for repair of the surviving patients. There were no significant complications from the cardiac repair. The history of significant force dispersed over a relatively small area of the precordium as in a kicking injury from an animal or steering wheel impact should alert the physician to possible cardiac rupture. Cardiac rupture should be considered in patients who present with signs of cardiac tamponade or persistent thoracic bleeding after blunt trauma. PMID:6708151

    王文林; 曾伟生; 蒋仁超


    The early diagnosis of cardiac rupture is one of the key factors for a successful outcome. However, the accurate diagnosis is often difficult in the early stage of injury, especially when some obvious severe wounds are found in other regions of the body,1,2 for they are easy to disguise the symptom of the heart. We report a case with cardiac rupture and liver trauma caused by traffic accident.

  5. Mini invasive hemodynamic monitoring: from arterial pressure to cardiac output



    To evaluate the Cardiac Output (CO) the standard invasive pulmonary artery catheter (PAC) is considered today the gold standard. The major criticism to the PAC is that its level of invasiveness is not supported by an improvement in patient's outcome. The interest to lesser and lesser invasive techniques is high. Therefore, the alternative techniques have been recently developed.Cardiac Output can be monitored continuously by different devices that analyze the arterial waveform to track change...

  8. Cardiac Target Organ Damage in Hypertension: Insights from Epidemiology

    Lawler, Patrick R.; Hiremath, Pranoti; Cheng, Susan


    Hypertension is an important risk factor implicated in the development of multiple common cardiac conditions, including coronary atherosclerosis, heart failure, and atrial fibrillation. Epidemiologic studies have provided insight into the shared pathogenesis of hypertension and subclinical as well as clinically evident cardiac diseases. The mechanistic common ground between chronic blood pressure elevation and cardiac disease likely begins early in life. Understanding these connections will aid ongoing efforts to identify individuals at risk, develop targeted therapeutics, and improve overall outcomes for individuals with elevated blood pressure in the population at large. PMID:24801135

  9. Cardiac computed tomography in patients with acute coronary syndrome

    Currently, cardiac computed tomography (CT) is increasingly being implemented into clinical algorithms, primarily due to substantial technical advances over the last decade. Its use in the setting of suspected acute coronary syndrome is of particular relevance, given the high degree of accumulating scientific evidence of improving patient outcomes. Performing cardiac CT requires specific knowledge on the available scan acquisitions and patient preparation. Also, expertise is required in order to interpret the coronary and extra-coronary findings adequately. The present article provides an overview of the different aspects on the use of cardiac CT in the setting of acute coronary syndrome.

  10. Cancer treatment-related cardiac toxicity: prevention, assessment and management.

    Fanous, Ibrahim; Dillon, Patrick


    Cancer therapies, especially anthracyclines and monoclonal antibodies, have been linked with increased rates of cardiotoxicity. The development of some cardiac side effects happens over several months, and changes in ejection fraction can be detected long before permanent damage or disability occurs. Advanced heart failure could be averted with better and earlier detection. Methodologies for early detection of cardiac changes include stress echocardiograms, cardiac velocity measurements, radionuclide imaging, cardiac MRI and several potential biomarkers. Many agents have been described for prophylaxis of cardiac events precipitated by cancer therapy. Prophylactic use of beta-blockers and ACE inhibitors may be considered for use with trastuzumab in breast cancer as tolerated. Recovery of cardiac function is possible early after the injury from a cancer therapy. Late complications for coronary artery disease, hypertension and arrhythmia are underappreciated. Treatments for severe cancer therapy-related cardiac complications follow the existing paradigms for congestive heart failure and coronary artery disease, although outcomes for cancer patients differ from outcomes for non-cancer patients.

  11. Ventilation and gas exchange management after cardiac arrest.

    Sutherasan, Yuda; Raimondo, Pasquale; Pelosi, Paolo


    For several decades, physicians had integrated several interventions aiming to improve the outcomes in post-cardiac arrest patients. However, the mortality rate after cardiac arrest is still as high as 50%. Post-cardiac arrest syndrome is associated with high morbidity and mortality due to not only poor neurological outcome and cardiovascular failure but also respiratory dysfunction. To minimize ventilator-associated lung injury, protective mechanical ventilation by using low tidal volume ventilation and driving pressure may decrease pulmonary complications and improve survival. Low level of positive end-expiratory pressure (PEEP) can be initiated and titrated with careful cardiac output and respiratory mechanics monitoring. Furthermore, optimizing gas exchange by avoiding hypoxia and hyperoxia as well as maintaining normocarbia may improve neurological and survival outcome. Early multidisciplinary cardiac rehabilitation intervention is recommended. Minimally invasive monitoring techniques, that is, echocardiography, transpulmonary thermodilution method measuring extravascular lung water, as well as transcranial Doppler ultrasound, might be useful to improve appropriate management of post-cardiac arrest patients. PMID:26670813

  12. Sudden Cardiac Death and Post Cardiac Arrest Syndrome. An Overview

    Zima Endre


    Full Text Available A satisfactory neurologic outcome is the key factor for survival in patients with sudden cardiac death (SCD, however this is highly dependent on the haemodynamic status. Short term cardiopulmonary resuscitation and regained consciousness on the return of spontaneous circulation (ROSC is indicative of a better prognosis. The evaluation and treatment of SCD triggering factors and of underlying acute and chronic diseases will facilitate prevention and lower the risk of cardiac arrest. Long term CPR and a prolonged unconscious status after ROSC, in the Intensive Care Units or Coronary Care Units, indicates the need for specific treatment and supportive therapy including efforts to prevent hyperthermia. The prognosis of these patients is unpredictable within the first seventy two hours, due to unknown responses to therapeutic management and the lack of specific prognostic factors. Patients in these circumstances require the highest level of intensive care and aetiology driven treatment without any delay, independently of their coma state. Current guidelines sugest the use of multiple procedures in arriving at a diagnosis and prognosis of these critical cases.

  13. [Cardiac evaluation before non-cardiac surgery].

    Menzenbach, Jan; Boehm, Olaf


    Before non-cardiac surgery, evaluation of cardiac function is no frequent part of surgical treatment. European societies of anesthesiology and cardiology published consensus-guidelines in 2014 to present a reasonable approach for preoperative evaluation. This paper intends to differentiate the composite of perioperative risk and to display the guidelines methodical approach to handle it. Features to identify patients at risk from an ageing population with comorbidities, are the classification of surgical risk, functional capacity and risk indices. Application of diagnostic means, should be used adjusted to this risk estimation. Cardiac biomarkers are useful to discover risk of complications or mortality, that cannot be assessed by clinical signs. After preoperative optimization and perioperative cardiac protection, the observation of the postoperative period remains, to prohibit complications or even death. In consideration of limited resources of intensive care department, postoperative ward rounds beyond intensive care units are considered to be an appropriate instrument to avoid or recognize complications early to reduce postoperative mortality.

  16. [Cardiac Rehabilitation 2015].

    Hoffmann, Andreas


    The goals of cardiac rehabilitation are (re-)conditioning and secondary prevention in patients with heart disease or an elevated cardiovascular risk profile. Rehabilitation is based on motivation through education, on adapted physical activity, instruction of relaxation techniques, psychological support and optimized medication. It is performed preferably in groups either in outpatient or inpatient settings. The Swiss working group on cardiac rehabilitation provides a network of institutions with regular quality auditing. Positive effects of rehabilitation programs on mortality and morbidity have been established by numerous studies. Although a majority of patients after cardiac surgery are being referred to rehabilitation, these services are notoriously underused after catheter procedures. PMID:26602848

  18. Molecular Basis of Cardiac Myxomas

    Pooja Singhal


    Full Text Available Cardiac tumors are rare, and of these, primary cardiac tumors are even rarer. Metastatic cardiac tumors are about 100 times more common than the primary tumors. About 90% of primary cardiac tumors are benign, and of these the most common are cardiac myxomas. Approximately 12% of primary cardiac tumors are completely asymptomatic while others present with one or more signs and symptoms of the classical triad of hemodynamic changes due to intracardiac obstruction, embolism and nonspecific constitutional symptoms. Echocardiography is highly sensitive and specific in detecting cardiac tumors. Other helpful investigations are chest X-rays, magnetic resonance imaging and computerized tomography scan. Surgical excision is the treatment of choice for primary cardiac tumors and is usually associated with a good prognosis. This review article will focus on the general features of benign cardiac tumors with an emphasis on cardiac myxomas and their molecular basis.

  20. Stroke of a cardiac myxoma origin

    Shi-Min Yuan


    Full Text Available AbstractObjective:The clinical features of cardiac myxoma stroke have not been sufficiently described. Debates remain concerning the options and timing of treatment and the clinical outcomes are unknown. This article aims to highlight the pertinent aspects of this rare condition.Methods:Data source of the present study came from a comprehensive literature collection of cardiac myxoma stroke in PubMed, Google search engine and Highwire Press for the year range 2000-2014.Results:Young adults, female predominance, single cerebral vessel (mostly the middle cerebral artery, multiple territory involvements and solitary left atrial myxoma constituted the outstanding characteristics of this patient setting. The most common affected cerebral vessel (the middle cerebral artery and areas (the basal ganglion, cerebellum and parietal and temporal regions corresponded well to the common manifestations of this patient setting, such as conscious alteration, ataxia, hemiparesis and hemiplegia, aphasia and dysarthria. Initial computed tomography scan carried a higher false negative rate for the diagnosis of cerebral infarction than magnetic resonance imaging did. A delayed surgical resection of cardiac myxoma was associated with an increased risk of potential consequences in particular otherwise arterial embolism. The mortality rate of this patient population was 15.3%.Conclusion:Cardiac myxoma stroke is rare. Often does it affect young females. For an improved diagnostic accuracy, magnetic resonance imaging of the brain and echocardiography are imperative for young stroke patients in identifying the cerebral infarct and determining the stroke of a cardiac origin. Immediate thrombolytic therapy may completely resolve the cerebral stroke and improve the neurologic function of the patients. An early surgical resection of cardiac myxoma is recommended in patients with not large territory cerebral infarct.

  7. Sudden cardiac death

    Aranđelović Aleksandra Č.


    Full Text Available Sudden cardiac death in an athlete is rare and tragic event. An athlete's death draws high public attention given that athletes are considered the healthiest category of society. The vast majority of sudden cardiac death in young athletes is due to congenital cardiac malformations such as hypertrophie cardiomyopathy and various coronary artery anomalies. In athletes over age 35, the usual cause of sudden cardiac death is coronary artery disease. With each tragic death of a young athlete, there is a question why this tragedy has not been prevented. The American College of Sports Medicine and the American Heart Association recommend that a pre-participation exam should include a complete cardiovascular history and physical examination.

    Objective:To investigate application of cardiopulmonary resuscitation(CPR) measures within the golden minutes inEurope.Methods:The material was taken from theUniversityClinical Center ofKosovo -EmergencyCentre inPristina, during the two(2) year period(2010-2011).The collected date belong to the patients with cardiac arrest have been recorded in the patients' log book protocol at the emergency clinic.Results:During the2010 to2011 in the emergency center of theCUCK inPristina have been treated a total of269 patients with cardiac arrest, of whom159 or59.1% have been treated in2010, and110 patients or40.9% in2011.Of the269 patients treated in the emergency centre,93 or34.6% have exited lethally in the emergency centre, and176 or 65.4% have been transferred to other clinics.In the total number of patients with cardiac arrest, males have dominated with186 cases, or69.1%.The average age of patients included in the survey was56.7 year oldSD±16.0 years.Of the269 patients with cardiac arrest, defibrillation has been applied for93 or34.6% of patients.In the outpatient settings defibrillation has been applied for3 or3.2% of patients.Patients were defibrillated with application of one to four shocks. Of27 cases with who have survived cardiac arrest, none of them have suffered cardiac arrest at home,3 or11.1% of them have suffered cardiac arrest on the street, and24 or88.9% of them have suffered cardiac arrest in the hospital.5 out of27 patients survived have ended with neurological impairment.Cardiac arrest cases were present during all days of the week, but frequently most reported cases have been onMonday with32.0% of cases, and onFriday with24.5% of cases. Conclusions:All survivors from cardiac arrest have received appropriate medical assistance within10 min from attack, which implies that if cardiac arrest occurs near an institution health care(with an opportunity to provide the emergent health care) the rate of survival is higher.

  10. Awareness in cardiac anesthesia.

    Serfontein, Leon


    Cardiac surgery represents a sub-group of patients at significantly increased risk of intraoperative awareness. Relatively few recent publications have targeted the topic of awareness in this group. The aim of this review is to identify areas of awareness research that may equally be extrapolated to cardiac anesthesia in the attempt to increase understanding of the nature and significance of this scenario and how to reduce it.

  11. Ranolazine in Cardiac Arrhythmia.

    Saad, Marwan; Mahmoud, Ahmed; Elgendy, Islam Y; Richard Conti, C


    Ranolazine utilization in the management of refractory angina has been established by multiple randomized clinical studies. However, there is growing evidence showing an evolving role in the field of cardiac arrhythmias. Multiple experimental and clinical studies have evaluated the role of ranolazine in prevention and management of atrial fibrillation, with ongoing studies on its role in ventricular arrhythmias. In this review, we will discuss the pharmacological, experimental, and clinical evidence behind ranolazine use in the management of various cardiac arrhythmias. PMID:26459200

  12. Cardiac tumours in infancy

    Yadava, O.P.


    Cardiac tumours in infancy are rare and are mostly benign with rhabdomyomas, fibromas and teratomas accounting for the majority. The presentation depends on size and location of the mass as they tend to cause cavity obstruction or arrhythmias. Most rhabdomyomas tend to regress spontaneously but fibromas and teratomas generally require surgical intervention for severe haemodynamic or arrhythmic complications. Other relatively rare cardiac tumours too are discussed along with an Indian perspect...

  13. Frequency and echocardiographic study of dilated cardiomyopathy in children presenting with cardiac failure

    Objective: To evaluate the role of echocardiography in diagnosis of dilated cardiomyopathy as a cause of cardiac failure in children. Design: This was descriptive study. Children presenting with cardiac failure from indoor patients were selected and echocardiography along with chest X- ray, ECG, cardiac enzymes and ASO titre was performed in all patients. Subject: Fifty hospitalized patients with congestive heart failure were selected consecutively from hospitalized patients. Main Outcome: Role of echocardiography in the diagnosis of dilated cardiomyopathy in children presenting with cardiac failure. Results: Out of fifty patients admitted with cardiac failure 27 (54%) cases were found to be dilated cardiomyopathy while congenital heart disease, myocarditis and rheumatic heart disease were found in 12 (24%), 8 (16%) and 3 (6%) cases respectively. Conclusion: Dilated cardiomyopathy is an important cause of cardiac failure in children and echocardiography is an important tool to diagnose and differentiate dilated cardiomyopathy from other causes of cardiac failure.

  14. Cardiac Image Registration


    Full Text Available Long procedure time and somewhat suboptimal results hinder the widespread use of catheter ablation of complex arrhythmias such as atrial fibrillation (AF. Due to lack of contrast differentiation between the area of interest and surrounding structures in a moving organ like heart, there is a lack of proper intraprocedural guidance using current imaging techniques for ablation. Cardiac image registration is currently under investigation and is in clinical use for AF ablation. Cardiac image registration, which involves integration of two images in the context of left atrium (LA, is intermodal, with the acquired image and the real-time reference image residing in different image spaces, and involves optimization, where one image space is transformed into the other. Unlike rigid body registration, cardiac image registration is unique and challenging due to cardiac motion during the cardiac cycle and due to respiration. This review addresses the basic principles of the emerging technique of registration and the inherent limitations as they relate to cardiac imaging and registration.

  16. Postoperative cardiac arrest due to cardiac surgery complications

    To examine the role of anesthetists in the management of cardiac arrest occurring in association with cardiac anesthesia. In this retrospective study we studied the potential performances for each of the relevant incidents among 712 patients undergoing cardiac operations at Golestan and Naft Hospitals Ahwaz between November 2006 and July 2008. Out of total 712 patients undergoing cardiac surgery, cardiac arrest occurred in 28 cases (3.9%) due to different postoperative complications. This included massive bleeding (50% of cardiac arrest cases, 1.9% of patients); pulseless supra ventricular tachycardia (28.5% of cardiac arrest cases, 1.1% of patients); Heart Failure (7% of cardiac arrest cases, 0.2% of patients); Aorta Arc Rapture (3.5% of cardiac arrest cases, 0.1% of patients); Tamponade due to pericardial effusion (3.5% of cardiac arrest cases, 0.1% of total patients); Right Atrium Rupture (3.5% of cardiac arrest cases, 0.1% of patients) were detected after cardiac surgery. Out of 28 cases 7 deaths occurred (25% of cardiac arrest cases, 0.1% of patients). The most prevalent reason for cardiac arrest during post operative phase was massive bleeding (50%) followed by pulseless supra ventricular tachycardia (28.5%). Six patients had some morbidity and the remaining 15 patients recovered. There are often multiple contributing factors to a cardiac arrest under cardiac anesthesia, as much a complete systematic assessment of the patient, equipment, and drugs should be completed. We also found that the diagnosis and management of cardiac arrest in association with cardiac anesthesia differs considerably from that encountered elsewhere. (author)

  17. Kidney transplantation from donors after cardiac death: uncontrolled versus controlled donation

    Hoogland, E.R.; Snoeijs, M.G.; Winkens, B.; Christaans, M.H.; Heurn, L.W. van


    Kidney donation after cardiac death has been popularized over the last decade. The majority of these kidneys are from controlled donors. The number of organs for transplantation can be further increased by uncontrolled donors after cardiac death. The outcome of uncontrolled compared to controlled do

  18. VSD following blunt cardiac trauma: MRI findings.

    Liguori, Andrew E; Maertins, Benjamin A; Richardson, Randy


    In this report, we describe the clinical and radiographic findings of ventricular septal defects (VSDs) following blunt cardiac trauma in two patients. VSDs following either penetrating or blunt cardiac trauma are a rare occurrence. The variable presentation and timing of symptom onset along with the common association of other injuries can make the diagnosis of a posttraumatic VSD difficult. Therefore, investigation should be initiated when elements from the history and physical examination (e.g., new onset murmur), laboratory tests (e.g., cardiac enzymes), EKG, and CT or echocardiography warrant it. The first patient was a 19-year-old male who was hemodynamically stable on initial presentation to this trauma center after a motor vehicle collision. A posttraumatic VSD was found by echocardiography on the day of admission and further defined on cardiac MRI (CMRI). The second patient was a 31-year-oid male who presented after a high-speed motorcycle accident and was found to have a VSD 40 days later on CMRI after a fluctuating clinical course and multiple normal echocardiograms. Both patients had good outcomes with subsequent surgical closure. PMID:23604922

  19. Minimally invasive cardiac surgery and transesophageal echocardiography

    Ajay Kumar Jha


    Full Text Available Improved cosmetic appearance, reduced pain and duration of post-operative stay have intensified the popularity of minimally invasive cardiac surgery (MICS; however, the increased risk of stroke remains a concern. In conventional cardiac surgery, surgeons can visualize and feel the cardiac structures directly, which is not possible with MICS. Transesophageal echocardiography (TEE is essential during MICS in detecting problems that require immediate correction. Comprehensive evaluation of the cardiac structures and function helps in the confirmation of not only the definitive diagnosis, but also the success of surgical treatment. Venous and aortic cannulations are not under the direct vision of the surgeon and appropriate positioning of the cannulae is not possible during MICS without the aid of TEE. Intra-operative TEE helps in the navigation of the guide wire and correct placement of the cannulae and allows real-time assessment of valvular pathologies, ventricular filling, ventricular function, intracardiac air, weaning from cardiopulmonary bypass and adequacy of the surgical procedure. Early detection of perioperative complications by TEE potentially enhances the post-operative outcome of patients managed with MICS.

  20. Diagnosis and treatment of cardiac sarcoidosis.

    Kusano, Kengo F; Satomi, Kazuhiro


    Sarcoidosis is a systemic granulomatous disease of unknown aetiology. The frequency of cardiac involvement (cardiac sarcoidosis (CS)) varies in the different geographical regions, but it has been reported that it is an absolutely important prognostic factor in this disease. Complete atrioventricular block is the most common, and ventricular tachycardia/ventricular fibrillation the second most common arrhythmia in this disease, both of which are associated with cardiac sudden death. Diagnosing CS is sometimes difficult because of the non-specific ECG and echocardiographic findings, and CS is sometimes misdiagnosed as dilated cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy or an idiopathic ventricular aneurysm, and therefore, endomyocardial biopsy is important, but has a low sensitivity. Another problem is the recognition of isolated types of CS. Recently, MRI and (18)F-fluorodeoxyglucose positron emission tomography have been demonstrated to be useful tools for the non-invasive diagnosis of CS as well as therapeutic evaluation tools, but are still unsatisfactory. Treatment of CS is usually done by corticosteroid therapy to control inflammation, prevent fibrosis and protect from any deterioration of the cardiac function, but the long-term outcome is still in debate. Despite the advancement of non-pharmacological approaches for CS (pacing, defibrillators and catheter ablation) to improve the prognosis, there are still many issues remaining to resolve diagnosing and managing CS. Here, we attempt a review of the clinical evidence, with special focus on the current understanding of this disease and showing the current strategies and remaining problems of diagnosing and managing CS.

  1. Therapeutic Hypothermia and Out-of-Hospital Cardiac Arrest in a Child with Hypertrophic Obstructive Cardiomyopathy

    Nancy Spurkeland


    Full Text Available Neurologic outcomes following pediatric cardiac arrest are consistently poor. Early initiation of cardiopulmonary resuscitation has been shown to have positive effects on both survival to hospital discharge, and improved neurological outcomes after cardiac arrest. Additionally, the use of therapeutic hypothermia may improve survival in pediatric cardiac arrest patients admitted to the intensive care unit. We report a child with congenital hypertrophic obstructive cardiomyopathy and an out-of-hospital cardiac arrest, in whom the early initiation of effective prolonged cardiopulmonary resuscitation and subsequent administration of therapeutic hypothermia contributed to a positive outcome with no gross neurologic sequelae. Continuing efforts should be made to promote and employ high-quality cardiopulmonary resuscitation, which likely contributed to the positive outcome of this case. Further research will be necessary to develop and solidify national guidelines for the implementation of therapeutic hypothermia in selected subpopulations of children with OHCA.

  3. Rare Intracardiac Tumor: Primary Cardiac Lymphoma Presenting as Atypical Angina

    Karthigesu Aimanan


    Full Text Available Primary lymphomas of the heart are extremely rare, accounting for 2% of all primary cardiac tumors. Due to the rare presentation, there is no proper consensus available on treatment strategy. Preoperative confirmation of the pathology is fundamental in guiding an early treatment plan, which allows for improved prognosis. Unfortunately, in most cases, primary cardiac lymphoma is only identified on postoperative histopathological analyses, which affect the treatment plan and outcome. Here, we report a unique case of primary cardiac lymphoma presented with dyspnea and reduced effort tolerance. Young age, rapid onset of symptom, and absence of cardiac risk factors prompted us towards further imaging and emergency resection. The patient received a course of postoperative chemotherapy and was disease-free on six months of follow-up.

  5. Cardiac Rehabilitation Enhancing Programs in Patients with Myocardial Infarction: A literature Review

    Ahyana Ahyana


    Full Text Available Background: Cardiac rehabilitation (CR is a process that involves a multidisciplinary team of health professionals in order to optimize the status of patients’ physical, psychological, social, and vocational well being. The CR program has been proven to influence health outcomes in patients with cardiac diseases, particularly myocardial infarction (MI and stable angina. However, patients’ compliance with cardiac rehabilitation programs remains a challenge.Purpose: The purpose of this study is to review and identify interventions that enhance cardiac rehabilitation behaviors in MI patients.Method: A literature review was conducted by analyzing related research reports published since 2000 to 2012. Only English language articles were included.Result: There were 10 experimental studies and 2 meta-analysis studies. Interventions widely used to enhance cardiac rehabilitation behaviors in MI patients were self-efficacy and self management derived programs. These programs involved interventions that enhance cardiac rehabilitation behaviors, including training exercise, behavioral change, education and psychological support, and lifestyle changing strategies. None have reported the use of culturally tailored intervention. Four phases of cardiac rehabilitation were accepted as each phase represents a different aspect of care: inpatient care, early post discharge period, exercise training, and long term follow up. Critical factors for patients in maintaining an optimum health condition after a cardiac event are, in order, status of patient’s physical, psychological, social, and vocational well being.Conclusion: Cardiac Rehabilitation program has been shown to improve quality of life and decrease mortality in MI patients. The development of culturally specific interventions to increase cardiac rehabilitation behaviors will provide a significant improvement for cardiac patient’s care that ultimately results in better health outcomes.

  6. Blood transfusion practices in cardiac anaesthesia

    Hanumantha Rao Mangu


    Full Text Available The primary reasons for blood transfusion in cardiac surgery are to correct anaemia and to improve tissue oxygen delivery. However, there is a considerable debate regarding the actual transfusion trigger at which the benefits of transfusion overweight the risk. The association between extreme haemodilution, transfusion and adverse outcome after cardio pulmonary bypass (CPB is not clear and the current available literature is not sufficient to provide a strong recommendation regarding the safe haematocrit range during CPB. There is no quality evidence to support use of fresh red blood cell except during massive transfusion or exchange transfusion in neonate. Overall concern regarding the safety of allogeneic blood transfusion resulted in the search for autologous blood transfusion and perioperative blood salvage. The aim of this review is to provide cardiac surgery specific clinically useful guidelines pertaining to transfusion triggers, optimal haemodilution during CPB, autologous blood transfusion and role of perioperative blood salvage based on available evidence.

  10. Pediatric cardiac postoperative care

    Auler Jr. José Otávio Costa


    Full Text Available The Heart Institute of the University of São Paulo, Medical School is a referral center for the treatment of congenital heart diseases of neonates and infants. In the recent years, the excellent surgical results obtained in our institution may be in part due to modern anesthetic care and to postoperative care based on well-structured protocols. The purpose of this article is to review unique aspects of neonate cardiovascular physiology, the impact of extracorporeal circulation on postoperative evolution, and the prescription for pharmacological support of acute cardiac dysfunction based on our cardiac unit protocols. The main causes of low cardiac output after surgical correction of heart congenital disease are reviewed, and methods of treatment and support are proposed as derived from the relevant literature and our protocols.

  14. Giant Cardiac Cavernous Hemangioma.

    Unger, Eric; Costic, Joseph; Laub, Glenn


    We report the case of an asymptomatic giant cardiac cavernous hemangioma in a 71-year-old man. The intracardiac mass was discovered incidentally during surveillance for his prostate cancer; however, the patient initially declined intervention. On presentation to our institution 7 years later, the lesion had enlarged significantly, and the patient consented to excision. At surgery, an 8 × 6.5 × 4.8 cm intracardiac mass located on the inferior heart border was excised with an intact capsule through a median sternotomy approach. The patient had an uneventful postoperative course. We discuss the diagnostic workup, treatment, and characteristics of this rare cardiac tumor. PMID:26140782

  15. Radiography in cardiology [cardiac disorders, cardiac insufficiency

    The diagnostic procedure in cardiology nearly always requires an X-ray examination of the thorax. This examination is very informative when it is correctly performed and interpreted. The radiographs need to be read precisely and comprehensively: this includes the evaluation of the silhouette of the heart (size, form and position) as well as the examination of extra-cardiac thoracic structures allowing among other things to search for signs of cardiac insufficiency. The conclusion of the X-ray examination can be drawn after having brought together information concerning the case history, the clinical examination and the study of the radiographs. The radiologist finds himself in one of three situations: (1) the information provided by the X-ray pictures is characteristic of a disease and permits a diagnosis, (2) the X-ray pictures indicate a group of hypotheses; further complementary tests could be useful and (3) the X-ray pictures provide ambiguous even contradictory information; it is necessary to complete the radiological examination by other techniques such as an ultrasonographic study of the heart

  17. Cardiac sarcoidosis—state of the art review

    Hulten, Edward; Aslam, Saira; Osborne, Michael; Abbasi, Siddique; Bittencourt, Marcio Sommer


    Sarcoidosis is a multi-system inflammatory disorder of unknown etiology resulting in formation of non-caseating granulomas. Cardiac involvement—which is associated with worse prognosis—has been detected in approximately 25% of individuals based on autopsy or cardiac imaging studies. Nevertheless, the diagnosis of cardiac sarcoidosis is challenging due to the low yield of endomyocardial biopsy, and the limited accuracy of various clinical criteria. Thus, no gold standard diagnostic criterion exists. This review will summarize the pathophysiology, diagnosis, and treatment of cardiac sarcoidosis with a focus on advanced cardiovascular imaging, We review the evidence to support a role for cardiac magnetic resonance (CMR) imaging in the initial evaluation of selected patients with suspected cardiac sarcoidosis, with cardiac positron emission tomography (PET) as an alternative or complementary initial diagnostic test in a subgroup of patients in whom CMR may be contra-indicated or when CMR is negative with continued clinical concern for myocardial inflammation. In addition to the diagnostic value of these tests, CMR and PET are also useful in identifying patients who have higher risk of adverse events such as ventricular tachycardia or death, in whom preventive therapies such as defibrillators should be more strongly considered. Although no randomized controlled trials for treatment of cardiac sarcoidosis exist, immunosuppressive therapy is often used. We review emerging evidence regarding the use of cardiac PET to identify and quantity the amount of myocardial inflammation as well as to guide the use of immunotherapy. Future studies are needed to determine the benefit of imaging guided therapies aimed at improving patient outcomes. PMID:26885492

    Study of 80 consecutive patients undergoing elective diagnostic cardiac catheterisation showed that after the procedure 25 (31%) developed myoglobinaemia. This was attributed to complications of the catheterisation in two. The remaining 23 had received premedication by intramuscular injection. In patients without intramuscular injections myoglobinaemia did not occur after uncomplicated cardiac catheterisation. The study did not support the proposition that cardiac catheterisation results in m...

  19. Hepato-cardiac disorders

    Yasser; Mahrous; Fouad; Reem; Yehia


    Understanding the mutual relationship between the liver and the heart is important for both hepatologists and cardiologists. Hepato-cardiac diseases can be classified into heart diseases affecting the liver, liver diseases affecting the heart, and conditions affecting the heart and the liver at the same time. Differential diagnoses of liver injury are extremely important in a cardiologist’s clinical practice calling for collaboration between cardiologists and hepatologists due to the many other diseases that can affect the liver and mimic haemodynamic injury. Acute and chronic heart failure may lead to acute ischemic hepatitis or chronic congestive hepatopathy. Treatment in these cases should be directed to the primary heart disease. In patients with advanced liver disease, cirrhotic cardiomyopathy may develop including hemodynamic changes, diastolic and systolic dysfunctions, reduced cardiac performance and electrophysiological abnormalities. Cardiac evaluation is important for patients with liver diseases especially before and after liver transplantation. Liver transplantation may lead to the improvement of all cardiac changes and the reversal of cirrhotic cardiomyopathy. There are systemic diseases that may affect both the liver and the heart concomitantly including congenital, metabolic and inflammatory diseases as well as alcoholism. This review highlights these hepatocardiac diseases

  20. Primary cardiac tumors

    Cardiac tumors happen to be among the less known pathologies without clear treatment standards. Even one decade ago most of the cardiac tumor diagnosis were made post mortem, and only reports of isolated cases could be found in the literature, showing the lack of interest in the investigation of these pathologies by cardiology and cardiovascular surgery specialists. With the development of echocardiography and of cardiovascular surgery, more cases of primary and metastatic cardiac tumors have been diagnosed. Many cases have been treated by palliative or curative surgical interventions, thus increasing the reports in the world literature and the experience in this field, and pointing out the real incidence of these pathologies, not being as bizarre as it had been considered. a revision of the literature will be made, in which the frequency and the suggested interventions will be reported, as well as the cases of cardiac pathology in two cardiovascular centers of the country known by the author. The echocardiographic, pathologic and histological characteristics of the representative cases will be presented, without a greater evidence level, due to the problem's incidence and the few cases reported by these centers

  1. Cardiac MRI tagging

    Cardiac MRI tagging is an original technique based upon the perturbation of the magnetization of determined regions of the myocardium (tags). The motion of the tags accurately reflects the deformation of the underlying tissue. Data analysis requires special techniques to reconstruct the 3D motion of the heart, and to evaluate the myocardial strain, locally and throughout the whole heart. (authors)

  3. Cardiac effects of vasopressin.

    Pelletier, Jean-Sébastien; Dicken, Bryan; Bigam, David; Cheung, Po-Yin


    Vasopressin is an essential hormone involved in the maintenance of cardiovascular homeostasis. It has been in use therapeutically for many decades, with an emphasis on its vasoconstrictive and antidiuretic properties. However, this hormone has a ubiquitous influence and has specific effects on the heart. Although difficult to separate from its powerful vascular effects in the clinical setting, a better understanding of vasopressin's direct cardiac effects could lead to its more effective clinical use for a variety of shock states by maximizing its therapeutic benefit. The cardiac-specific effects of vasopressin are complex and require further elucidation. Complicating our understanding include the various receptors and secondary messengers involved in vasopressin's effects, which may lead to various results based on differing doses and varying environmental conditions. Thus, there have been contradictory reports on vasopressin's action on the coronary vasculature and on its effect on inotropy. However, beneficial results have been found and warrant further study to expand the potential therapeutic role of vasopressin. This review outlines the effect of vasopressin on the coronary vasculature, cardiac contractility, and on hypertrophy and cardioprotection. These cardiac-specific effects of vasopressin represent an interesting area for further study for potentially important therapeutic benefits. PMID:24621650

  5. [Cardiac amyloidosis. General review].

    Laraki, R


    Cardiac amyloidosis, most often of AL type, is a non-exceptional disease as it represents 5 to 10% of non-ischemic cardiomyopathies. It realizes typically a restrictive cardiomyopathy. Nevertheless the wide diversity of possible presentation makes it a "big shammer" which must be evoked in front of every unexplained cardiopathy after the age of forty. If some associated manifestations can rapidly suggest the diagnosis, as a peripheric neuropathy especially a carpal tunnel syndrome or palpebral ecchymosis, cardiac involvement can also evolve in an apparently isolated way. The most suggestive paraclinic elements for the diagnosis are, in one hand, the increased myocardial echogenicity with a "granular sparkling" appearance seen throughout all walls of the left ventricle and, in the other hand, the association of a thickened left ventricle and a low voltage (electrocardiogram could also show pseudo-infarct Q waves). In front of such aspects, the proof of amyloidosis is brought by an extra-cardiac biopsy or by scintigraphy with labelled serum amyloid P component, so that the indications of endomyocardial biopsy are very limited today. The identification of the amyloid nature of a cardiopathy has an direct therapeutic implication: it contra-indicates the use of digitalis, calcium channel blockers and beta-blockers. The treatment of AL amyloidosis (chemotherapy with alkylant agents) remains very unsatisfactory especially in the cardiac involvement which is the most frequent cause of death (in AL amyloidosis). Last, cardiac amyloidosis is a bad indication for transplantation which results are burden by rapid progression of deposits especially in the gastro-intestinal tract and the nervous system.

    Goo, Hyun Woo; Park, Sang-Hyub; Koo, Hyun Jung; Cho, Young Hoon; Lee, Eunsol [University of Ulsan College of Medicine, Asan Medical Center, Department of Radiology and Research Institute of Radiology, Seoul (Korea, Republic of)


    Imaging findings of bilateral pulmonary vein atresia have not been described. To describe cardiac CT findings and clinical outcomes of bilateral pulmonary vein atresia. Three newborns with bilateral pulmonary vein atresia were encountered at our institution during a period of 8 years. We evaluated prenatal echocardiographic findings, clinical presentations, postnatal echocardiographic findings, chest radiographic findings, cardiac CT findings and clinical outcomes. All newborns presented immediately after birth with severe cyanosis, respiratory distress and acidosis that were unresponsive to medical management. Prenatal and postnatal echocardiographic studies and chest radiography were misleading, inconclusive or nonspecific in making the diagnosis in these children; however cardiac CT clearly demonstrated atresia of the bilateral pulmonary veins with multiple small mediastinal collateral veins and pulmonary edema. Surgical treatments were not feasible for this anomaly. Their clinical outcomes were universally dismal and all infants died within 3 days. Cardiac CT provides an accurate diagnosis of bilateral pulmonary vein atresia and leads to prompt treatment decision in these children. (orig.)

  9. Anemia in Intensive Cardiac Care Unit patients - An underestimated problem.

    Uscinska, Ewa; Idzkowska, Ewelina; Sobkowicz, Bozena; Musial, Wlodzimierz J; Tycinska, Agnieszka M


    The heterogeneous group of patients admitted to Intensive Cardiac Care Unit (ICCU) as well as nonspecific complaints associated with anemia might be the reason for underdiagnosing or minimization of this problem. Because of this heterogeneity, there are no clear guidelines to follow. It is known that anemia is impairing the outcome. Thus, it is crucial to keep alert in the diagnosis and treatment of anemia, especially in critically ill cardiac patients. The greatest groups of patients admitted to ICCU are those with acute coronary syndromes (ACS), acute decompensated heart failure (ADHF), severe arrhythmias as well as individuals after cardiac operations. However, patients suffering other critical cardiac illnesses quite often become anemic during hospitalization in ICCU. It is because anemia is typed in the clinical features of heavy diseases or may be the consequence of treatment. The current review focuses on the incidence, complex etiology and predictive role of anemia in a diverse group of ICCU patients. It discusses clinical aspects of anemia treatment in particular groups of critically ill cardiac patients because proper treatment increases chances for recovery and improves the outcome in this severe group of patients.

  10. Genetic and physiologic dissection of the vertebrate cardiac conduction system.

    Neil C Chi


    Full Text Available Vertebrate hearts depend on highly specialized cardiomyocytes that form the cardiac conduction system (CCS to coordinate chamber contraction and drive blood efficiently and unidirectionally throughout the organism. Defects in this specialized wiring system can lead to syncope and sudden cardiac death. Thus, a greater understanding of cardiac conduction development may help to prevent these devastating clinical outcomes. Utilizing a cardiac-specific fluorescent calcium indicator zebrafish transgenic line, Tg(cmlc2:gCaMP(s878, that allows for in vivo optical mapping analysis in intact animals, we identified and analyzed four distinct stages of cardiac conduction development that correspond to cellular and anatomical changes of the developing heart. Additionally, we observed that epigenetic factors, such as hemodynamic flow and contraction, regulate the fast conduction network of this specialized electrical system. To identify novel regulators of the CCS, we designed and performed a new, physiology-based, forward genetic screen and identified for the first time, to our knowledge, 17 conduction-specific mutations. Positional cloning of hobgoblin(s634 revealed that tcf2, a homeobox transcription factor gene involved in mature onset diabetes of the young and familial glomerulocystic kidney disease, also regulates conduction between the atrium and the ventricle. The combination of the Tg(cmlc2:gCaMP(s878 line/in vivo optical mapping technique and characterization of cardiac conduction mutants provides a novel multidisciplinary approach to further understand the molecular determinants of the vertebrate CCS.
