    Diabetes mellitus (DM) and metabolic syndrome are important targets for secondary prevention in cardiovascular disease. However, the prevalence in patients undergoing elective percutaneous coronary intervention is not well defined. We aimed to analyse the prevalence and characteristics of patients undergoing percutaneous coronary intervention with previously unrecognized prediabetes, diabetes and metabolic syndrome. Data were collected from 740 patients undergoing elective percutaneous coronary intervention between November 2010 and March 2013 at a tertiary referral center. Prevalence of DM and prediabetes was evaluated using Haemoglobin A1c (A1c ≥ 6.5% for DM, A1c 5.7-6.4% for prediabetes). A modified definition was used for metabolic syndrome [three or more of the following criteria: body mass index ≥30 kg/m2; triglycerides ≥ 150 mg/dL; high density lipoprotein prediabetes at time of percutaneous coronary intervention. Overall, 54.9% met criteria for metabolic syndrome (69.2% of patients with DM and 45.8% of patients without DM). Among patients undergoing elective percutaneous coronary intervention, a substantial number were identified with a new DM, prediabetes, and/or metabolic syndrome. Routine screening for an abnormal glucometabolic state at the time of revascularization may be useful for identifying patients who may benefit from additional targeting of modifiable risk factors.

    Aortic valve calcification (AVC) is a common progressive condition that involves several inflammatory and atherosclerotic mediators. However, it is unclear whether the occurrence of periprocedural myocardial injury (PMI) after elective coronary intervention is associated with AVC in stable coronary artery disease (CAD) patients. A total of 530 stable CAD patients who underwent elective coronary intervention were enrolled in this clinical study. High sensitive cardiac troponin T (hs-cTnT) was detected before and after the procedure. PMI was defined as hs-cTnT after coronary intervention higher than 99th percentile upper reference limit (URL). All patients underwent echocardiography to detect the occurrence of AVC. Univariate and multivariate analyses were applied to analyze risk factors of PMI. A total of 210 patients (39.6 %) were diagnosed with PMI after elective coronary intervention. Compared with non-AVC patients (n = 386), AVC patients (n = 144) had higher rate of PMI (64.6 vs. 30.3 %, P AVC had higher Gensini score (39.9 ± 26.6 vs. 34.2 ± 22.1, P AVC patients had increased risk of PMI compared with non-AVC patients. Importantly, even after being adjusted by multivariate analysis, AVC still independently increased the risk of PMI (OR = 3.329, 95 % CI = 2.087-5.308, P AVC significantly increased the risk of PMI after elective coronary intervention. It could be one of the independent predictors for PMI in stable CAD patients.

    To clarify the effect of single-session multivessel percutaneous coronary intervention (PCI) strategy relative to the staged multivessel strategy on clinical outcomes in patients with stable coronary artery disease (CAD) or non-ST-elevation acute coronary syndrome. In the Coronary REvascularisation Demonstrating Outcome Study in Kyoto PCI/coronary artery bypass grafting registry cohort-2, there were 2018 patients who underwent elective multivessel PCI. Primary outcome measure was composite of all-cause death, myocardial infarction and stroke at 5-year follow-up. Single-session multivessel PCI and staged multivessel PCI were performed in 707 patients (35.0%) and 1311 patients (65.0%), respectively. The cumulative 5-year incidence of and adjusted risk for the primary outcome measure were not significantly different between the single-session and staged groups (26.7% vs 23.0%, p=0.45; HR 0.91, 95% CI 0.72 to 1.16, p=0.47). The 30-day incidence of all-cause death was significantly higher in the single-session group than in the staged group (1.1% vs 0.2%, p=0.009). However, the causes of death in 11 patients who died within 30 days were generally not related to the procedural complications, but related to the serious clinical status before PCI. For the subgroup analyses including age, gender, extent of CAD, severe chronic kidney disease and heart failure, there was no significant interaction between the subgroup factors and the effect of the single-session strategy relative to the staged strategy for the primary outcome measure. The single-session multivessel PCI strategy was associated with at least comparable 5-year clinical outcomes compared with the staged multivessel PCI, although the prevalence of the single-session strategy was low in the present study. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Warfarin discontinuation with heparin bridging is a common practice in patients receiving warfarin prior to elective coronary angiography (CAG). The uninterrupted warfarin strategy has been suggested to be alternative option for patients with high thromboembolic risk. Therefore, we aimed to assess the safety of elective transfemoral CAG during uninterrupted warfarin therapy compared to heparin bridging. This study was a randomized open-label design with blinded event evaluation. The 110 consecutive patients (age ≥ 18 years) receiving warfarin before the planned transfemoral CAG were randomly assigned to either heparin bridging or uninterrupted warfarin with targeted INR (2.0-3.0). The primary outcome was the incidence of major vascular access site complications. The baseline characteristics were comparable between two groups (mean age was 60.1 ± 7.8 years, 49 males). The mean INR on the day of CAG of heparin bridging and uninterrupted warfarin groups was 1.2 ± 0.3 and 2.2 ± 0.5 (P warfarin patients (P = 0.243). The total vascular access site complications occurred in 6 (10.9%) heparin-bridging and one (1.8%) uninterrupted warfarin patients (P = 0.113). No patient developed either other bleeding or thromboembolic events during 7 days after CAG. We demonstrated that an uninterrupted warfarin strategy did not increase vascular access site complications in patients undergoing transfemoral CAG compared to heparin bridging therapy. Due to the safety and the ease of uninterrupted warfarin strategy, this approach should be encouraged in patients receiving long-term warfarin who undergo elective transfemoral CAG. © 2017, Wiley Periodicals, Inc.

    We describe a case of coronary stenosis located in an unprotected left main coronary artery, treated primarily and electively with the placement of a coronary stent. As a function of the large mass of myocardium involved, this patient would be considered a classical candidate for direct surgery, because the inherent risk involved with conventional balloon angioplasty, mainly due to the eventual occurrence of acute closure during the procedure. Since the previsibility of the immediate results with the use of coronary stents was significantly improved, we propose this new therapeutic approach for this traditionally surgical case, that has been performed with success and without any complication. This strategy for the treatment of unprotected left main lesions with the elective placement of Palmaz-Schatz stents, has not yet been proposed or applied in our country, and may represent a new universe of indication of percutaneous treatment of coronary artery disease, no longer approaching the left main stem only in special or emergency situations, usually a result of complications of left main manipulation during angioplasty of the coronary system. The patient involved in this case did not show any contraindication for the treatment with conventional open heart surgery.

    The Veterans Affairs (VA) Community Care (CC) Program supplements VA care with community-based medical services. However, access gains and value provided by CC have not been well described. To compare the access, cost, and quality of elective coronary revascularization procedures between VA and CC hospitals and to evaluate if procedural volume or publicly reported quality data can be used to identify high-value care. Observational cohort study of veterans younger than 65 years undergoing an elective coronary revascularization, controlling for differences in risk factors using propensity adjustment. The setting was VA and CC hospitals. Participants were veterans undergoing elective percutaneous coronary intervention (PCI) and veterans undergoing coronary artery bypass graft (CABG) procedures between October 1, 2008, and September 30, 2011. The analysis was conducted between July 2014 and July 2017. Receipt of an elective coronary revascularization at a VA vs CC facility. Access to care as measured by travel distance, 30-day mortality, and costs. In the 3 years ending on September 30, 2011, a total of 13 237 elective PCIs (79.1% at the VA) and 5818 elective CABG procedures (83.6% at the VA) were performed in VA or CC hospitals among veterans meeting study inclusion criteria. On average, use of CC was associated with reduced net travel by 53.6 miles for PCI and by 73.3 miles for CABG surgery compared with VA-only care. Adjusted 30-day mortality after PCI was higher in CC compared with VA (1.54% for CC vs 0.65% for VA, P publicly reported mortality data identified hospitals that provided higher-value care with the exception that CABG mortality was lower in small-volume CC hospitals. In this veteran cohort, PCIs performed in CC hospitals were associated with shorter travel distance but with higher mortality, higher costs, and minimal travel savings compared with VA hospitals. The CABG procedures performed in CC hospitals were associated with shorter travel distance

    Retrospective cohort. Determine whether surgeon demographic factors influence postoperative complication rates after elective spine fusion procedures. Surgeon demographic factors have been shown to impact decision making in the management of degenerative disease of the lumbar spine. Complication rates are frequently reported outcome measurements used to evaluate surgical treatments, quality-of-care, and determine health care reimbursements. However, there are few studies investigating the association between surgeon demographic factors and complication outcomes after elective spine fusions. A database of US spine surgeons with corresponding postoperative complications data after elective spine fusions was compiled utilizing public data provided by the Centers for Medicare and Medicaid Services (2011-2013) and ProPublica Surgeon Scorecard (2009-2013). Demographic data for each surgeon was collected and consisted of: surgical specialty (orthopedic vs. neurosurgery), years in practice, practice setting (private vs. academic), type of medical degree (MD vs. DO), medical school location (United States vs. foreign), sex, and geographic region of practice. General linear mixed models using a Beta distribution with a logit link and pairwise comparison with post hoc Tukey-Kramer were used to assess the relationship between surgeon demographics and complication rates. 2110 US-practicing spine surgeons who performed spine fusions on 125,787 Medicare patients from 2011 to 2013 met inclusion criteria for this study. None of the surgeon demographic factors analyzed were found to significantly affect overall complication rates in lumbar (posterior approach) or cervical spine fusion. Publicly available complication rates for individual spine surgeons are being utilized by hospital systems and patients to assess aptitude and gauge expectations. The increasing demand for transparency will likely lead to emphasis of these statistics to improve outcomes. We conclude that none of the

    Previous studies suggest that among patients with stable coronary artery disease, patients with diabetes mellitus (DM) have less angina and more silent ischemia when compared with those without DM. However, the burden of angina in diabetic versus nondiabetic patients after elective percutaneous coronary intervention (PCI) has not been recently examined. In a 10-site US PCI registry, we assessed angina before and at 1, 6, and 12 months after elective PCI with the Seattle Angina Questionnaire angina frequency score (range, 0-100, higher=better). We also examined the rates of antianginal medication prescriptions at discharge. A multivariable, repeated-measures Poisson model was used to examine the independent association of DM with angina over the year after treatment. Among 1080 elective PCI patients (mean age, 65 years; 74.7% men), 34.0% had DM. At baseline and at each follow-up, patients with DM had similar angina prevalence and severity as those without DM. Patients with DM were more commonly prescribed calcium channel blockers and long-acting nitrates at discharge (DM versus not: 27.9% versus 20.9% [ P =0.01] and 32.8% versus 25.5% [ P =0.01], respectively), whereas β-blockers and ranolazine were prescribed at similar rates. In the multivariable, repeated-measures model, the risk of angina was similar over the year after PCI in patients with versus without DM (relative risk, 1.04; range, 0.80-1.36). Patients with stable coronary artery disease and DM exhibit a burden of angina that is at least as high as those without DM despite more antianginal prescriptions at discharge. These findings contradict the conventional teachings that patients with DM experience less angina because of silent ischemia. © 2017 American Heart Association, Inc.

    Coronary artery fistula is an uncommon clinical entity. The most common coronary artery fistula is from the right coronary artery to the right side of the heart, and it is less frequent to the pulmonary artery. The effect of a coronary artery fistula may be physiologically significant because of the steal phenomenon resulting in coronary ischemia. Based on published reports, it is recommended that patients with congenital coronary artery fistulas be considered candidates for elective surgical correction to prevent complications including development of congestive heart failure, angina, subacute bacterial endocarditis, myocardial infarction, and coronary aneurysm formation with rupture or embolization. A patient is presented in whom treadmill-exercise thallium imaging was effective in determining the degree of coronary steal from a coronary artery fistula, leading to successful corrective surgery.

    The clinical spectrum of sigmoid diverticulitis (SD) varies from asymptomatic diverticulosis to symptomatic disease with potentially fatal complications. Sigmoid colectomy with restoration of continuity has been the prevailing modality for treating acute and recurrent SD, and is often performed as a laparoscopy-assisted procedure. For elective sigmoid colectomy, the postoperative morbidity rate is 15-20% whereas morbidity rates reach up to 30% in patients who undergo emergency surgery for perforated SD. Some of the more common and serious surgical complications after sigmoid colectomy are anastomotic leaks and peritonitis, wound infections, small bowel obstruction, postoperative bleeding, and injuries to the urinary tract structures. Regarding the management of complications, it makes no difference whether the complication is a result of an emergency or an elective procedure. The present work gives an overview of the management of complications in the surgical treatment of SD based on the current literature. To achieve successful management, early diagnosis is mandatory in cases of deviation from the normal postoperative course. If diagnostic procedures fail to deliver a correlate for the clinical situation of the patient, re-laparotomy or re-laparoscopy still remain among the most important diagnostic and/or therapeutic principles in visceral surgery when a patient's clinical status deteriorates. The ability to recognize and successfully manage complications is a crucial part of the surgical treatment of diverticular disease and should be mastered by any surgeon qualified in this field.

    Many anesthesiologists are unfamiliar with the rate of surgical neurological complications of the shoulder and elbow procedures for which they provide local anesthetic-based anesthesia and/or analgesia. Part 1 of this narrative review series on neurological complications of elective orthopedic surgery describes the mechanisms and likelihood of peripheral nerve injury associated with some of the most common shoulder and elbow procedures, including open and arthroscopic shoulder procedures, elbow arthroscopy, and total shoulder and elbow replacement. Despite the many articles available, the overall number of studied patients is relatively low. Large prospective trials are required to establish the true incidence of neurological complications following elective shoulder and elbow surgery. As the popularity of regional anesthesia increases with the development of ultrasound guidance, anesthesiologists should have a thoughtful understanding of the nerves at risk of surgical injury during elective shoulder and elbow procedures.

    Periprocedural myocardial injury (PMI) is a major complication of percutaneous coronary intervention (PCI) and is associated with atherosclerotic coronary plaque and worse clinical outcomes. High-density lipoprotein cholesterol (HDL-C) is a protective factor for cardiovascular disease. However, the role of HDL-C subfractions, such as HDL2 cholesterol (HDL2-C) or HDL3 cholesterol (HDL3-C), in cardiovascular disease remains unclear. The purpose of the study was to investigate the relationship between HDL2-C and HDL3-C subfractions and the incidence of PMI in patients who underwent elective PCI. We enrolled 129 patients who underwent elective PCI for stable angina pectoris. PMI was defined as an increase in high-sensitivity troponin T levels > 5 times the upper normal limit (> 0.070 ng/mL) at 24 h after PCI. Serum HDL-C subfractions (HDL2-C and HDL3-C) were assessed using ultracentrifugation in patients with and those without PMI. HDL3-C levels were significantly lower in patients with PMI than in those without (15.1 ± 3.0 mg/dL vs. 16.4 ± 2.9 mg/dL, p = 0.016) and had an independent and inverse association with PMI (odds ratio, 0.86; 95% confidence interval, 0.74-0.99; p = 0.038). When divided by the cut-off value of HDL3-C for PMI (14.3 mg/dL), the incidence of PMI was significantly higher in low HDL3-C patients than in high HDL3-C patients (51.2% vs. 30.2%, p = 0.020). HDL3-C was an independent inverse predictor of PMI in patients who underwent elective PCI.

    Stroke after percutaneous coronary intervention (PCI) is a serious complication, but its determinants and outcomes after PCI in different clinical settings are poorly documented. The British Cardiovascular Intervention Society (BCIS) database was used to study 560 439 patients who underwent PCI in England and Wales between 2006 and 2013. We examined procedural-type specific determinants of ischemic and hemorrhagic stroke and the likelihood of subsequent 30-day mortality and in-hospital major adverse cardiovascular events (a composite of in-hospital mortality, myocardial infarction or reinfarction, and repeat revascularization). A total of 705 stroke cases were recorded (80% ischemic). Stroke after an elective PCI or PCI for acute coronary syndrome indications was associated with a higher risk of adverse outcomes compared with those without stroke; 30-day mortality and major adverse cardiovascular events outcomes in fully adjusted model were odds ratios 37.90 (21.43-67.05) and 21.05 (13.25-33.44) for elective and 5.00 (3.96-6.31) and 6.25 (5.03-7.77) for acute coronary syndrome, respectively. Comparison of odds of these outcomes between these 2 settings showed no differences; corresponding odds ratios were 1.24 (0.64-2.43) and 0.63 (0.35-1.15), respectively. Hemorrhagic and ischemic stroke complications are uncommon, but serious complications can occur after PCI and are independently associated with worse mortality and major adverse cardiovascular events outcomes in both the elective and acute coronary syndrome setting irrespective of stroke type. Our study provides a better understanding of the risk factors and prognosis of stroke after PCI by procedure type, allowing physicians to provide more informed advice around stroke risk after PCI and counsel patients and their families around outcomes if such neurological complications occur. © 2016 American Heart Association, Inc.

    Full Text Available Abstract Rationale There is growing evidence that obstructive sleep apnea is associated with coronary artery disease. However, there are no data on the course of coronary stenosis after percutaneous coronary intervention in patients with obstructive sleep apnea. Objectives To determine whether sleep apnea is associated with increased late lumen loss and restenosis after percutaneous coronary intervention. Methods 78 patients with coronary artery disease who underwent elective percutaneous coronary intervention were divided in 2 groups: 43 patients with an apnea hypopnea – Index 10/h (group II. Late lumen loss, a marker of restenosis, was determined using quantitative coronary angiography after 6.9 ± 3.1 months. Main results Angiographic restenosis (>50% luminal diameter, was present in 6 (14% of group I and in 9 (25% of group II (p = 0.11. Late lumen loss was significant higher in pt. with an AHI > 10/h (0.7 ± 0.69 mm vs. 0.38 ± 0.37 mm, p = 0.01. Among these 35 patients, 21(60% used their CPAP devices regularly. There was a marginally lower late lumen loss in treated patients, nevertheless, this difference did not reach statistical significance (0.57 ± 0.47 mm vs. 0.99 ± 0.86 mm, p = 0.08. There was no difference in late lumen loss between treated patients and the group I (p = 0.206. Conclusion In summary, patients with OSA and coronary artery disease have a higher degree of late lumen loss, which is a marker of restenosis and vessel remodeling after elective percutaneous intervention.

    The 'weekend' effect is a controversial theory that links reduced staffing levels, staffing seniority and supportive services at hospitals during 'out-of-office hours' time periods with worsening patient outcomes. It is uncertain whether admitting elective surgery patients to intensive care units (ICU) during 'out-of-office hours' time periods mitigates this affect through higher staffing ratios and seniority. Over a 3-year period in Western Australia's largest private hospital, this retrospective nested-cohort study compared all elective surgical patients admitted to the ICU based on whether their admission occurred 'in-office hours' (Monday-Friday 08.00-18.00 hours) or 'out-of-office hours' (all other times). The main outcomes were surgical complications using the Dindo-Clavien classification and length-of-stay data. Of the total 4363 ICU admissions, 3584 ICU admissions were planned following elective surgery resulting in 2515 (70.2%) in-office hours and 1069 (29.8%) out-of-office hours elective ICU surgical admissions. Out-of-office hours ICU admissions following elective surgery were associated with an increased risk of infection (P = 0.029), blood transfusion (P = 0.020), total parental nutrition (P office hours ICU admissions were also associated with an increased hospital length-of-stay, with (1.74 days longer, P office hours ICU admissions following elective surgery is common and associated with serious post-operative complications culminating in significantly longer hospital length-of-stays and greater transfers with important patient and health economic implications. © 2017 Royal Australasian College of Surgeons.

    Cardiac troponin detected by new-generation, highly sensitive assays predicts clinical outcomes among patients with stable coronary artery disease (SCAD) treated medically. The prognostic value of baseline high-sensitivity cardiac troponin T (hs-cTnT) elevation in SCAD patients undergoing elective percutaneous coronary interventions is not well established. This study assessed the association of preprocedural levels of hs-cTnT with 1-year clinical outcomes among SCAD patients undergoing percutaneous coronary intervention. Between 2010 and 2014, 6974 consecutive patients were prospectively enrolled in the Bern Percutaneous Coronary Interventions Registry. Among patients with SCAD (n=2029), 527 (26%) had elevated preprocedural hs-cTnT above the upper reference limit of 14 ng/L. The primary end point, mortality within 1 year, occurred in 20 patients (1.4%) with normal hs-cTnT versus 39 patients (7.7%) with elevated baseline hs-cTnT (P<0.001). Patients with elevated hs-cTnT had increased risks of all-cause (hazard ratio 5.73; 95% confidence intervals 3.34-9.83; P<0.001) and cardiac mortality (hazard ratio 4.68; 95% confidence interval 2.12-10.31; P<0.001). Preprocedural hs-TnT elevation remained an independent predictor of 1-year mortality after adjustment for relevant risk factors, including age, sex, and renal failure (adjusted hazard ratio 2.08; 95% confidence interval 1.10-3.92; P=0.024). A graded mortality risk was observed across higher tertiles of elevated preprocedural hs-cTnT, but not among patients with hs-cTnT below the upper reference limit. Preprocedural elevation of hs-cTnT is observed in one fourth of SCAD patients undergoing elective percutaneous coronary intervention. Increased levels of preprocedural hs-cTnT are proportionally related to the risk of death and emerged as independent predictors of all-cause mortality within 1 year.

    Complications associated with prone surgical positioning during elective spine surgery have the potential to cause serious patient morbidity. Although many of these complications remain uncommon, the range of possible morbidities is wide and includes multiple organ systems. Perioperative visual loss (POVL) is a well described, but uncommon complication that may occur due to ischemia to the optic nerve, retina, or cerebral cortex. Closed-angle glaucoma and amaurosis have been reported as additional etiologies for vision loss following spinal surgery. Peripheral nerve injuries, such as those caused by prolonged traction to the brachial plexus, are more commonly encountered postoperative events. Myocutaneous complications including pressure ulcers and compartment syndrome may also occur after prone positioning, albeit rarely. Other uncommon positioning complications such as tongue swelling resulting in airway compromise, femoral artery ischemia, and avascular necrosis of the femoral head have also been reported. Many of these are well-understood and largely avoidable through thoughtful attention to detail. Other complications, such as POVL, remain incompletely understood and thus more difficult to predict or prevent. Here, the current literature on the complications of prone positioning for spine surgery is reviewed to increase awareness of the spectrum of potential complications and to inform spine surgeons of strategies to minimize the risk of prone patient morbidity.

    Marriage confers various health advantages in the general population. However, the added value of marriage among patients who undergo percutaneous coronary intervention (PCI) beyond the standard cardiovascular risk factors is not clear. This study aimed to assess the effects of marital status on outcomes of patients undergoing elective or urgent PCI. Clinical observational analysis of consecutive patients undergoing elective or urgent PCI from 1993 to 2011 was performed. Patients were stratified by marital status, comparing married to unmarried patients. Clinical outcome up to 12 months was obtained by telephone contact or office visit. A total of 11,216 patients were included in the present analysis; 55% were married and 45% unmarried. Significant differences in baseline characteristics were noted, including a lower prevalence of hypertension (86% vs 88%), diabetes (34% vs 38%), and smoking (19% vs 25%) among married vs unmarried patients, respectively (P married patients had a higher prevalence of hypercholesterolemia and family history of coronary artery disease. Early and late major adverse cardiac event rates were significantly lower for married vs unmarried patients up to 1 year (13.3% vs 8.2%, P Married status was independently associated with improved outcome in multivariable analysis (hazard ratio 0.7, 95% CI 0.6-0.9). Married patients who undergo urgent or elective PCI have superior short- and long-term outcomes up to 1 year when compared with unmarried patients. These benefits persist after adjustment for multiple traditional cardiovascular risk factors. © 2013.

    Full Text Available Background: Right Ventricular (RV dysfunction has been introduced as a predictor of mortality in acute myocardial infarction. Objectives: This study aimed to investigate the effect of right coronary revascularization on systolic and diastolic RV dysfunction. Patients and Methods: This study was conducted on unstable angina patients who were candidate for elective Percutaneous Revascularization Intervention (PCI on the right coronary artery. The participants were initially evaluated by transthoracic echocardiography and tissue Doppler imaging prior to PCI and the RV function parameters were assessed. Echocardiography was repeated two months after PCI and the results were compared with baseline. Paired t-test was used to compare the pre- and post-procedural measurements. Besides, Pearson’s correlation was used to find out the linear association between the RV function parameters and Left Ventricular Ejection Fraction (LVEF. P value < 0.05 was considered as statistically significant. Results: This study was conducted on 30 patients (mean age = 60.00 ± 8.44 years; 24 [80%] males. In the pre-procedural echocardiography, 15 patients (50% had normal RV function, 14 patients (46.7% had grade-1 RV dysfunction, and only 1 patient (3.3% had grade-2 RV dysfunction. Following PCI, however, all the patients had normal systolic and diastolic RV functions. Comparison of echocardiographic RV function parameters showed an improvement in both systolic and diastolic functional parameters of the RV. Nonetheless, no significant correlation was observed between these parameters and Left Ventricular (LV function. Conclusions:: A significant improvement was found in RV function, but not LV function, after right coronary PCI. Revascularization of the right coronary artery may be beneficial for the patients who suffer from RV failure due to ischemia

    Interventricular septal hematoma is a rare complication of retrograde chronic total occlusion (CTO) percutaneous coronary interventions (PCI) with a typically benign course. Here we report two cases of interventricular septal hematoma and coronary-cameral fistula development after right coronary artery (RCA) CTO-PCI using a retrograde approach. Both were complicated by development of ST-segment elevation and chest pain. One case was managed actively and the other conservatively, both with a f...

    We report a case of 30 year old alcoholic male admitted with vomiting, drowsiness, limb weakness and fasciculations after alleged history of consumption of 30 ml of chlorpyriphos insecticide. He had low serum cholinesterase levels. With standard treatment for organophosphorus poisoning (OPP), he improved gradually until day 5, when he developed neck and limb weakness and respiratory distress. This intermediate syndrome was treated with oximes, atropine and artificial ventilation. During treatment, his ECG showed fresh changes of ST elevation. High CPK & CPK-MB levels, septal hypokinesia on 2D echo suggested acute coronary syndrome. Coronary angiography was postponed due to his bedridden and obtunded status. The patient finally recovered fully by day 15 and was discharged. Acute coronary syndrome is a rare occurrence in OP poisoning. The present case thus emphasises the need for careful electrocardiographic and enzymatic monitoring of all patients of organophosphorus poisoning to prevent potential cardiac complication which can prove fatal.

    We sought to determine whether eptifibatide decreases the incidence of in-laboratory angiographic complications and to determine the relationship of angiographically evident complications to elevations of creatine kinase-MB (CK-MB) enzyme levels during percutaneous coronary intervention. In the Enhanced Suppression of the Platelet IIb/IIIa Receptor with Integrilin Therapy (ESPRIT) trial, eptifibatide during coronary intervention was associated with decreased ischemic complications at 48 h and 30 days. Patients (n = 2,064) were randomized to placebo versus eptifibatide (two 180 microg/kg boluses 10 min apart and as a continuous infusion of 2 microg/kg per min) during percutaneous coronary stenting. Angiographic complications including major dissection, distal embolization, residual thrombus, abrupt closure, residual stenosis >50% and side-branch occlusion were prospectively recorded by the operator. Creatine kinase-MB levels were measured after the procedure and every 6 h thereafter. The incidence of angiographic complications and CK-MB elevation was determined for eptifibatide versus placebo groups. Eptifibatide-treated patients demonstrated nonsignificant trends toward fewer angiographic complications (10 vs. 12% for placebo patients, p = 0.13) and, for patients with angiographic complications, fewer subsequent CK-MB elevations (43 vs. 50% for placebo patients, p = 0.31). In patients without any angiographic complications, the incidence of CK-MB elevation >3 times the normal was 7% with placebo and 4% with eptifibatide (p = 0.003). Eptifibatide during nonurgent coronary stent intervention only minimally (and insignificantly) reduces the incidence of angiographic complications and subsequent CK-MB elevations in patients developing an angiographic complication. The greater effect is to reduce myocardial infarction in patients undergoing otherwise uneventful coronary stent implantation as well as in the overall study population.

    The aim of this study is to investigate the association between fractional flow reserve (FFR) values and change in coronary physiological indices after elective percutaneous coronary intervention (PCI). Decision making for revascularization when FFR is 0.75-0.80 is controversial. A retrospective analysis was performed of 296 patients with stable angina pectoris who underwent physiological examinations before and after PCI. To investigate the differences of coronary flow improvement between territories with low-FFR (zone FFR (0.75-0.80), serial changes in physiological indices including mean transit time (Tmn), coronary flow reserve (CFR), and index of microcirculatory resistance (IMR) were compared between these two groups. Compared to low-FFR territories, grey-zone FFR territories showed significantly lower prevalence of Tmn shortening, CFR improvement, and decrease in IMR (Tmn shorting, 63.9% vs. 87.0%, P 51.3% vs. 63.3%, P = .040) and lower extent of their absolute changes (Tmn shorting, 0.06 (-0.03 to 0.16) vs. 0.22 (0.07-0.45), P zone FFR. Physiological assessment combining FFR and IMR may help identify patients who may benefit by PCI, particularly those in the grey zone. © 2018 Wiley Periodicals, Inc.

    Contrast induced nephropathy (CIN) is the third lead cause of hospital acquired renal failure and was associated with significant morbidity and mortality. We hypothesized that hypertension is an independent risk factor for the development of CIN in patients undergoing elective percutaneous coronary intervention (PCI). The case-control method was used, 138 patients scheduled for elective PCI. We measured serum creatinine at baseline and after 24 hours of the procedure. CIN was defined as arising in serum creatinine of at least 44 μmol/l (0,5 mg/dl) or 25% rise from baseline. All patients received low osmolality nonionic contrast during PCI. Hypertension was defined as self-reported a history of treated or untreated diagnosed high blood pressure. One hundred thirty-eight patients (74,6%) were male, and 35 patients (25,4%) were female. Among the 138 patients, 86 (62,3%) were hypertensive patients whereas 52 (37,7%) were nonhypertensive patients. There was no difference in baseline serum creatinine levels and the amount of contrast media in patient with and without CIN. CIN developed in 42 patients, 39 patients (92,9%) were hypertensive compared to 3 patients (7,1%) without hypertension with p value < 0,05. (Odds ratio 16,8, 95% CI 4.542 - 62,412). This study showed that hypertension was a risk factor for the development of CIN

    Objective: To determine the outcomes of primary percutaneous coronary intervention for ST elevation myocardial infarction complicated by cardiogenic shock. Methods: The retrospective study was conducted at the Tabba Heart Institute, a private-sector facility in Karachi. It reviewed the medical records of 56 consecutive patients between January 2009 and June 2011 with acute ST elevation myocardial infarction complicated by cardiogenic shock and subjected to primary percutaneous coronary intervention. The primary end point was in-hospital mortality and its predictors. SPSS 14 was used for statistical analysis. Results: The mean age of the study patients was 63+-11.7 years; 38 (68%) were male; 32 (57%) were hypertensive; and 39 (69%) were diabetic. Most infarcts were anterior in location (n=36; 64%). Besides, 33 (59%) required ventilatory support. Intra-aortic balloon pump was placed in 30 (54%), and 33 (59%) patients had multivessel coronary artery disease. In-hospital mortality occurred in 26 (46%). Multivariate logistic regression analysis showed that age >60 years (p= 0.05), diabetes (p <0.01) and left ventricular ejection fraction <40% (p= 0.01) were independent predictors of in-hospital mortality. Conclusions: Results emphasise the need of aggressive management of patients with cardiogenic shock utilising primary percutaneous coronary intervention as a reperfusion strategy to improve clinical outcomes.

    Conclusion: On applying the 2012 updated AUC, about 5 % of overall elective PCI were deemed as ‘inappropriate’. About four in every five elective PCI in the non-ACS setting were of ‘uncertain’ appropriateness. The implementation of the GHIS not only significantly reduced the gender bias and delay in seeking interventional coronary care but also led to a significant rise in the proportion of PCI performed in the ACS setting. However, there was also a rise in ‘inappropriate’ PCI in the ACS setting and a significant fall in ‘appropriate’ PCI in the non-ACS setting after introduction of the GHIS..

    Prediabetes is an independent risk factor for cardiovascular disease. However, data on the long term adverse clinical outcomes of prediabetic patients undergoing percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) are scarce. The study population comprised 674 consecutive non-diabetic patients who underwent elective PCI between April 2007 and November 2010. Prediabetes was defined as hemoglobin A1c (HbA1c) of 5.7% to 6.4%. Two-year cumulative clinical outcomes of prediabetic patients (HbA1c of 5.7% to 6.4%, n=242) were compared with those of a normoglycemic group (prediabetes group. There was no significant difference between the two groups in coronary angiographic parameters, except for a higher incidence of diffuse long lesion in the prediabetes group. For prediabetic patients, trends toward higher incidences of binary restenosis (15.6% vs. 9.8 %, p=0.066) and late loss (0.71±0.70 mm vs. 0.59±0.62 mm, p=0.076) were noted. During the 24 months of follow up, the incidence of mortality in prediabetic patients was higher than that in normoglycemic patients (5.5% vs. 1.5%, p=0.007). In our study, a higher death rate and a trend toward a higher incidence of restenosis in patients with prediabetes up to 2 years, compared to those in normoglycemic patients, undergoing elective PCI with contemporary DESs. © Copyright: Yonsei University College of Medicine 2018.

    Full Text Available The optimal treatment approach for coronary intramural hematomas has not been well defined, and discussion is limited to scarce data. In addition, the impact of prior thrombolytic therapy in the setting of coronary artery dissections with possible development and/or extension of an intramural hematoma is not well understood. We describe a case of iatrogenic periprocedural dissection of the left anterior descending artery (LAD with development of an intramural hematoma and the extension of this hematoma to the left main (LM and left circumflex (LCX arteries in a middle-aged female, where prior recent thrombolytic therapy may have played a role in its triggering or facilitation of its extension. This case highlights the importance of facilitation of bleeding complications by prior use of thrombolytic therapy not only peripherally but intracoronary too and the use of intravascular ultrasound for both diagnosis, followup, and percutaneous coronary intervention (PCI guidance.

    The long-term prognosis of patients with Kawasaki disease (KD) complicated by coronary artery aneurysm (CAA) is unclear. The aim of this study was to evaluate the complications of KD with CAAs. We retrospectively analyzed the clinical data and complications of 38 KD patients with CAAs who were treated and underwent regular follow-up with echocardiography between January 1989 and May 2013. During a period of 29 days to 19 years after disease onset, complications seen included coronary stenosis and occlusion (six patients), thrombosis (17 patients), myocardial infarction (six patients), and calcification of CAAs (seven patients). Rupture of giant CAAs occurred in two patients and caused sudden death in one of these patients at 29 days and in the other patient at 5 months after disease onset. A total of seven deaths occurred, with five deaths caused by myocardial infarction. Three of these had undiagnosed incomplete KD or had not received regular treatment, while two experienced sudden death after several asymptomatic myocardial infarctions. Cardiac complications of KD with CAAs include thrombosis, coronary stenosis, myocardial infarction, sudden death, and calcification. Although rare, rupture of giant CAAs is fatal and might occur earlier after the onset of disease. Mortality occurred primarily in the earlier cases when anticoagulant therapy was insufficient and in patients who did not receive regular treatment. Echocardiography can provide reliable information for assessing the progression and prognosis of this condition. © 2015, Wiley Periodicals, Inc.

    Contrast-induced nephropathy (CIN) is an important complication following percutaneous coronary intervention (PCI). The clinical importance of a minimum contrast media volume (CMV) for PCI to prevent CIN has not been well evaluated. The purpose of this study was to evaluate the impact of minimum CMV to prevent CIN after PCI. In this study, 2052 consecutive patients who underwent elective PCI in our institute were analyzed. We divided patients into two groups according to CMV: a minimum CMV PCI group [CMV ≤50 ml (n = 94)] and a non-minimum CMV PCI group [CMV >50 ml (n = 1958)]. CIN occurred in 160 (7.8 %) patients. The incidence of CIN was significantly lower in the minimum CMV PCI group than in the non-minimum CMV PCI group (2.1 vs. 8.1 %; P = 0.03). According to multivariate analysis, elderly patients and diabetes mellitus patients were at high risk of developing CIN in this study population. When analyzing only high-risk patients, the incidence of CIN was also significantly lower in the minimum CMV group than in the non-minimum CMV group (2.6 vs. 10.3 %; P = 0.03). Minimum CMV PCI could reduce the incidence of CIN, particularly in high-risk patients; as such, defining the minimum CMV clinical cut-off values may be useful for the prevention of CIN.

    Many people believe that the moon has an influence on daily life, and some even request elective surgery dates depending on the moon calendar. The aim of this study was to assess the influence of 'unfavorable' lunar or zodiac constellations on perioperative complications and outcome in elective surgery for degenerative disc disease. Retrospective database analysis including 924 patients. Using uni- and multivariate logistic regression, the likelihood for intraoperative complications and re-do surgeries as well as the clinical outcomes at 4 weeks was analyzed for surgeries performed during the waxing moon, full moon, and dates when the moon passed through the zodiac sign 'Leo.' In multivariate analysis, patients operated on during the waxing moon were 1.54 times as likely as patients who were operated on during the waning moon to suffer from an intraoperative complication (OR 1.54, 95 % CI 1.07-2.21, p = 0.019). In contrast, there was a trend toward fewer re-do surgeries for surgery during the waxing moon (OR 0.51, 95 % CI 0.23-1.16, p = 0.109), while the 4-week responder status was similar (OR 0.73, 95 % CI 0.47-1.14, p = 0.169). A full moon and the zodiac sign Leo did not increase the likelihood for complications, re-do surgeries or unfavorable outcomes. We found no influence of 'unfavorable' lunar or zodiac constellations on the 4-week responder status or the revision rate that would justify a moon calendar-based selection approach to elective spine surgery dates. However, the fact that patients undergoing surgery during the waxing moon were more likely to suffer from an intraoperative complication is a surprising curiosity and defies our ability to find a rational explanation.

    Blunt chest trauma can cause a wide variety of injuries including acute myocardial infarction (AMI). Although AMI due to coronary artery dissection caused by blunt chest trauma is very rare, it is associated with high morbidity and mortality. In the vast majority of patients with AMI, primary percutaneous coronary interventions (PCI) are performed to recanalize obstructed arteries, but PCI carries a substantial risk of hemorrhagic complications in the acute phase of trauma. We report a case of AMI due to right coronary artery (RCA) dissection caused by blunt chest trauma. The totally obstructed RCA was spontaneously recanalized with medical therapy. We could avoid primary PCI in the acute phase of blunt chest trauma because electrocardiogram showed early reperfusion signs. We performed an elective PCI in the subacute phase when the risk of bleeding subsided. Since the risk of severe hemorrhagic complications is greater in the acute phase of blunt chest trauma as compared with the late phase, deferring emergency PCI is reasonable if signs of recanalization are observed.

    Cardiovascular complications are important causes of morbidity and mortality in patients undergoing elective non-cardiac surgery, with adverse cardiac outcomes estimated to occur in approximately 4% of all patients. Anti-platelet therapy withdrawal may precede up to 10% of acute cardiovascular syndromes, with withdrawal in the peri-operative setting incompletely appraised. The aims of our study were to determine the proportion of patients undergoing elective non-cardiac surgery currently prescribed anti-platelet therapy, and identify current practice in peri-operative management. In addition, the relationship between management of anti-platelet therapy and peri-operative cardiac risk was assessed. We evaluated consecutive patients attending elective non-cardiac surgery at a major tertiary referral centre. Clinical and biochemical data were collected and analysed on patients currently prescribed anti-platelet therapy. Peri-operative management of anti-platelet therapy was compared with estimated peri-operative cardiac risk. Included were 2950 consecutive patients, with 516 (17%) prescribed anti-platelet therapy, primarily for ischaemic heart disease. Two hundred and eighty nine (56%) patients had all anti-platelet therapy ceased in the peri-operative period, including 49% of patients with ischaemic heart disease and 46% of patients with previous coronary stenting. Peri-operative cardiac risk score did not influence anti-platelet therapy management. Approximately 17% of patients undergoing elective non-cardiac surgery are prescribed anti-platelet therapy, the predominant indication being for ischaemic heart disease. Almost half of all patients with previous coronary stenting had no anti-platelet therapy during the peri-operative period. The decision to cease anti-platelet therapy, which occurred commonly, did not appear to be guided by peri-operative cardiac risk stratification. Copyright © 2012 Elsevier Ireland Ltd.

    We determined the timing of ischemic complications within 30 days after percutaneous coronary intervention (PCI) in patients enrolled in the Enhanced Suppression of the Platelet IIb/IIIa Receptor with Integrilin Therapy (ESPRIT) trial. Complications (death, myocardial infarction [MI], target vessel revascularization) occurred in 178 of 2064 patients (8.6%) within 30 days. More than 85% of complications occurred within the 24 hours following randomization, with the greatest risk hazard at 12-18 hours. Unexpectedly, 31% of patients who ultimately met criteria for an endpoint MI within 24 hours of PCI had completely normal CK-MB concentrations at the first 6-hour measurement. There was no rebound increase in events after cessation of eptifibatide. Treatment benefit persisted to 30 days. Post-procedural MI is often not detected until greater than or equal to 12 hours after PCI. Treatment with a glycoprotein IIb/IIIa inhibitor is the only modifiable parameter that reduces the risk for early ischemic complications.

    Full Text Available Objective: Postoperative atrial fibrillation is a common complication after cardiac surgery, with an incidence as high as 20-50%. Increased age is associated with a significant increase in postoperative atrial fibrillation risk. This common complication is associated with higher morbidity and mortality rates. The aim of this study was to assess the efficacy of nebivolol in preventing atrial fibrillation following coronary artery bypass surgery in patients over 60 years of age. Methods: In this prospective randomized study, 200 patients who were candidates for elective coronary artery bypass surgery were divided into two groups. The first group was administered with nebivolol and the second group was administered with metoprolol. Treatment was initiated four days prior to surgery, and patients were monitored for atrial fibrillation until discharge. Forty-one patients recieved 50 mg metoprolol succinate daily, which was initiated minimum 4 days before surgery. Results: Demographic data were similar in both groups. The incidence of postoperative atrial fibrillation in both groups was similar, with no significant difference being identified [n=20 (20%; n=18 (18%, P=0.718; respectively]. There were not any mortality at both groups during study. Inotropic agent requirement at ICU was similar for both groups [n=12 (12%, n=18 (18%, P=0.32]. Conclusion: We compared the effectiveness of nebivolol and metoprolol in decreasing the incidence of postoperative atrial fibrillation, and determined that nebivolol was as effective as metoprolol in preventing postoperative atrial fibrillation at patients. Nebivolol may be the drug of choice due to its effects, especially after elective coronary artery bypass surgery.

    Pheochromocytoma is a rare neuroendocrine tumor with a highly variable clinical presentation. The serious and potentially lethal cardiovascular complications of these tumors are related to the effects of secreted catecholamines. We describe a case of a 50-year-old woman urgently admitted to our hospital because of symptoms and clinical and instrumental findings consistent with an acute coronary syndrome complicated by acute heart failure. Urgent coronary angiography showed normal coronary arteries. During her hospital stay, the recurrence of episodes characterized by a sudden increase in blood pressure, cold sweating, and nausea allowed us to hypothesize a pheochromocytoma. The diagnosis was confirmed by elevated levels of urinary catecholamines and by the finding of a left adrenal mass on magnetic resonance imaging. The patient underwent left adrenalectomy. Therefore, the initial diagnosis was critically reappraised and reviewed as a cardiac manifestation of a pheochromocytoma during catecholaminergic crisis.

    Antibiotic prophylaxis has been recommended to reduce post-operative infectious complications. Discontinuation of post-operative antibiotic administration within 24 hours of operation is currently recommended. Many surgeons, however, conventionally tend to extend the duration of prophylactic antibiotic use. In this study, we performed a retrospective analysis to assess the efficacy of extended post-operative antibiotic use in patients who underwent elective liver resection. A total of 208 consecutive patients who underwent liver resection without biliary reconstruction were investigated. Patients were divided into two groups according to the duration of post-operative antibiotic use: Only once after the operation (the post-operative day [POD] 0 group) and until three days after the operation (the POD 3 group). Post-operative complications in the two groups were analyzed and compared. Incisional surgical site infections (SSIs) were observed in 5% of the POD 0 group and 3% of the POD 3 group (p = 0.517). Organ/space SSIs were observed in 2% of the POD 0 group and 3% of the POD 3 group (p = 0.694). Overall infectious complications including SSIs and remote site infections were observed in 12% of the POD 0 group and 11% of the POD 3 group. Multi-variable analyses revealed that the short-term post-operative antibiotic regimen did not confer additional risk for infectious complications. In elective liver resection, the administration of prophylactic antibiotics on the operative day alone appears to be sufficient, because no additional benefit in the incidence of post-operative infectious complications was conferred on patients given antibiotic agents for three days.

    During recent 10-15 years, percutaneous coronary interventions (PCI) have reached a new level of efficacy and safety. Rate of serious coronary complications has decreased. That to a greater degree exposes the problem of peripheral complications at the site of arterial approach. At the same time portion of patients older than 75 years in the total pool of PCI constantly increases. Number of patients with pronounced obesity also grows each year. Radial approach for PCI allows to substantially decrease rate of peripheral complications at the account of lowered rate of bleedings, and to shorten duration of hospitalization. In this literature review we present results of a number of relevant clinical studies including those which contained groups of elderly patients and of patients with obesity. We also have summarized main advantages and disadvantages of radial approach as compared with femoral approach for coronary angiography and PCI.

    Managing haemostasis in patients undergoing cardiopulmonary bypass (CPB) surgery remains a challenge. There is no established laboratory test to predict transfusion requirements in cardiac surgery. We investigated whether preoperative Thromboelastography (TEG) with Platelet Mapping Assay (PMA......) or Multiple Electrode Aggrometry (MEA) could predict transfusion requirements in patients undergoing elective coronary artery bypass grafting (CABG) or combined CABG with aortic or mitral valve replacement. We prospectively investigated 199 patients undergoing elective CABG or combined procedures. PMA and MEA...

    Periprocedural myocardial injury (PMI) following percutaneous coronary intervention (PCI) has received great attention due to its significant association with mortality and morbidity. Accordingly, cardioprotection during PCI is one of the important therapeutic concerns. Regarding the potential cardiovascular benefits of pentoxifylline this study was performed to evaluate whether the pretreatment pentoxifylline could reduce PMI in patients who are undergoing elective PCI. A randomized clinical trial on 85 patients undergoing elective PCI was performed. The intervention group (n = 41) received 1200 mg pentoxifylline in divided doses plus the standard treatment before PCI, while the control group (n = 44) received the standard treatment. For assessing myocardial damage during PCI, the levels of CK-MB and troponin-I were measured at baseline, 8, and 24 h after the procedure. Then, patients were followed up for a 1-month period regarding the major adverse cardiac effect. Comparing with the control group, no significant change of CK-MB at 8 (p = 0.315) and 24 h (p = 0.896) after PCI was documented in pentoxifylline group. Similarly, no significant change was found in troponin-I at 8 (p = 0.141) and 24 h (p = 0.256) after PCI. This study could not support the pretreatment with pentoxifylline in the prevention of PMI in patients undergoing elective PCI. However, the trend was toward the potential benefit of pentoxifylline.

    Single coronary artery arising from aortic root, is a rare congenital anomaly. A 30-year-old male presented with acute myocardial infarction (MI) complaining of chest pain and raised troponin levels. Emergency angiography showed no coronary lesions but both left and right coronary arteries arising from single ostium. Patient was operated electively and perioperative findings confirmed the diagnosis of single coronary artery, as left coronary artery after taking origin from right sinus of valsalva runs through the septum, before dividing into left anterior descending and circumflex branches. The single coronary ostium opened with a slit like incision over the course of left main coronary, making the size of ostium three to four times bigger than the native one. In addition left internal mammary artery was harvested and grafted to the left anterior descending branch distally. Patient made successful recovery. Four months follow up dobutamine stress echo showed no inducible ischemia.

    Objective: The purpose of the present study was to assess the feasibility, success, and safety of the transradial approach (TRA) for diagnostic coronary angiography. Study Design: Descriptive study. Place and Duration of Study: The study was carried out in Armed Forces Institute of Cardiology- National Institute of Heart Diseases (AFIC-NIHD) over a period of ten months from June 2009 to March 2010. Patients and Methods: We collected data of 500 consecutive patients who underwent coronary catheterization by the transradial approach. Transradial access was performed only if the Allen's test was normal (positive). Patients with previous CABG or requiring right heart catheterization were excluded from this study. Study endpoints included procedure success rate, vascular complications at access site, and major adverse cardiac and cerebrovascular events during hospitalization. Results: Mean age of the patients was 52 years (range 33-77 yrs) and 72.8% (n= 364) were men and 27.2% (n=136) were females. The vast majority of cases (98.4%) were elective. The right radial artery was used in 98% of cases. Procedural success was achieved in 90.6% cases (453/500). No case of vascular complications such as major access site bleeding, vascular perforation, radial artery occlusion, forearm ischemia, compartment syndrome or MACE was observed. Conclusion: Transradial access for coronary angiography is a safe, effective and elegant alternative to trans femoral access. (author)

    Few cases of Churg-Strauss syndrome (CSS) complicated by giant coronary aneurysms (CAs)have been reported thus far. We report a case of CSS in a 60-year-old man who underwent surgery for giant CAs, and was managed with anesthetics. The patient developed acute myocardial infarction, and was diagnosed with giant CAs in the right coronary artery (RCA, 11 cm) and circumflex artery (3 cm). The CA in RCA was communicating with the right ventricle. He had a history of pericardiectomy for pericarditis caused by the CSS and developed thrombocytopenia due to consumptive coagulopathy within the CAs. An operation, including ligation and excision of the CAs, and coronary artery bypass grafting was performed under general anesthesia and cardiopulmonary bypass. There was massive hemorrhage followed by hemodynamic instability while detaching the tight pericardial adhesion and fragile surface of the CAs. Massive transfusion was required along with inotropes administration and intraaortic balloon support. In this case, determination of the appropriate surgical timing was difficult because symptoms of the CSS became worse followed by rapid enlargement of the CAs, myocardial infarction, and thrombocytopenia. Steroids were administered for treating CSS, and the blood transfusion was sufficient. However, it was difficult to control the hemorrhage and maintain hemodynamic stability.

    Full Text Available Multivessel coronary spasm resulting to cardiogenic shock and malignant ventricular arrhythmias though rare has been reported in the literature. The disease seems to be more prevalent in Asians. There have been isolated reports of coronary spasm in patients with reactive airway disease. We report the first case of spontaneous multivessel spasm in a male patient with bronchial asthma of Arab ethnicity resulting in acute myocardial infarction complicated by cardiogenic shock, recurrent ventricular arrhythmias, and transient complete heart block. Literature review of similar cases suggests a strong association with bronchial asthma and a more malignant course in patients with reactive airway disease. The role of intracoronary nitroglycerin in proving the diagnosis even in patients in shock on maximal inotropic supports and intra-aortic balloon pump is highlighted and the importance of considering multivessel coronary spasm as a cause for acute coronary syndrome even in patients with conventional risk factors for atherosclerotic coronary artery disease is reinforced in the discussion of this case.

  14. Clinical review: Bleeding - a notable complication of treatment in patients with acute coronary syndromes: incidence, predictors, classification, impact on prognosis, and management

    2013-01-01

    This article focuses on the incidence, predictors, classification, impact on prognosis, and management of bleeding associated with the treatment of acute coronary syndrome. The issue of bleeding complications is related to the continual improvement of ischemic heart disease treatment, which involves mainly (a) the widespread use of coronary angiography, (b) developments in percutaneous coronary interventions, and (c) the introduction of new antithrombotics. Bleeding has become an important health and economic problem and has an incidence of 2.0% to 17%. Bleeding significantly influences both the short- and long-term prognoses. If a group of patients at higher risk of bleeding complications can be identified according to known risk factors and a risk scoring system can be developed, we may focus more on preventive measures that should help us to reduce the incidence of bleeding.

    Cocaine is a frequently used recreational drug which imposes important health problems with even life-threatening cardiotoxicity. The therapeutic use of cocaine is nowadays restricted to topical anesthesia in ophthalmological and nasal surgery but the possible hazards of this local anesthesia are not always fully appreciated. A 51-year old male patient with moderate cardiovascular risk profile underwent elective nasal surgery and cocaine was used as a local anesthetic. During surgery, ventricular arrhythmias and cardiogenic shock occurred, mimicking an ST-segment elevation myocardial infarction (STEMI) in sinus rhythm. Coronary angiography showed diffuse spasm of the right coronary artery (RCA) which disappeared with intracoronary nitrates. Urine analysis was positive for cocaine. The patient recovered completely with a normal echocardiography and ECG at discharge. Cocaine cardiotoxicity is not uncommon in the community but a particular situation arises when used in medicine as a topical anesthetic. This is the first case report, to our knowledge, of a cardiogenic shock mimicking a STEMI with documentation of diffuse coronary spasm after cocaine use in nasal surgery. One must be aware of the potential life-threatening complications in this low-risk surgery, moreover when safer alternatives are available.

    Full Text Available Introduction: The recently introduced technique of warm heart surgery may be a very effective method of myocardial protection. Although the systemic effects of hypothermic cardiopulmonary bypass are well known, the effects of warm heart surgery are not. Methods: In a prospective trial, 60 patients undergoing an elective coronary artery bypass grafting were randomly allocated to normothermic(30 patients and hypothermic(30 patients group and assessments regarding renal, respiratory and neurologic complications and bleeding volume was done. Resulst: Eighty percent of hypothermic group and 86% of normothermic group were males (p=0/36. Mean age was 56.4 and 56.1 years in hypothermic and normothermic groups, respectively. Groups had similar central temperature, shivering, nipride usage, intake and output, bleeding volume, neurologic complications and ICU staying(p>0/05 but inotrop usage and incidence of phrenic nerve palsy were higher in hypothermic group(p<0/05. Conclusion: Hypothermic procedure leads to a lower rate of respiratory complications, therefore we recommend replacing hypothermic procedure by normothermic one.

    Full Text Available Background: Coronary angiography can cause complications of arterial and subcutaneous bleeding (hematoma and back pain. Changing the position of the patient (positioning in bed can reduce the pain post-diagnostic catheterization complications. Objective: This study was to examine the effect of positioning on bleeding complication and low back pain after diagnostic coronary angiography in patients with coronary heart disease patient in the Integrated Heart Care Center in Indonesia. Methods: This study was a true-experimental study with randomized posttest-only control group design. Thirty respondents were randomly selected using simple random sampling, which 15 respondents were randomly assigned in the experiment group and control group. The experiment group was given a positioning with 150, 300, 450 head-of-bed elevation in left and right lateral position. An arc tool was used to measure the height of head of bed elevation, a measuring cup to measure arterial bleeding using, a perforated transparent plastic with 5 cm diameter to measure subcutaneous bleeding (hematoma, and Numeric Pain Rating Scale to measure low back pain. Data were analyzed using Kolmogorov- Smirnov and Repeated Measured ANOVA. Results: Findings showed that positioning had no effect on arterial hemorrhage (ρ=1.000 and subcutaneous bleeding (hematoma (ρ=0.999. Repeated ANOVA test results revealed that positioning had a significant effect on low back pain (ρ=0.017. Conclusion: There was no significant effect of positioning on the occurrence of arterial and subcutaneous bleeding (hematoma, but there was a significant effect in reducing low back pain.

    To compare the incidence of femoral access puncture site complications in the control group, who underwent 6 hr of bed rest, with patients in the case group, who underwent 4 hr of bed rest. The ideal bed rest length after percutaneous coronary intervention with a 7-French arterial sheath has been investigated by nursing practice. However, in this larger-sheath-size group, best practices have not been determined, and bed rest time continues to vary markedly among institutions. Retrospective study. Data were retrieved from the National Cardiovascular Data Registry and electronic health records in this retrospective study. Sample size was 401 patients: 152 case patients with 4-hr bed rest and 249 controls with 6-hr bed rest. Case group data were obtained from 20 May 2013-31 December 2014; and control group data, 15 June 2011-20 May 2013. National Cardiovascular Data Registry event rates were generally low in both groups: Only three patients in each group had a bleeding event within 72 hr (2% vs. 1%) and no patient and only two controls had arteriovenous fistula (0% vs. 1%). Complications documented in the electronic health records with institutional femoral access puncture site complication definitions identified bleeding at the access site in eight case patients (5%) and nine controls (4%). Haematoma at the access site occurred in 21 case patients (14%) and 25 controls (10%). The practice change of decreasing bed rest from 6-4 hr for patients with 7-French arterial sheaths post-percutaneous coronary intervention was associated with no significant change in femoral access puncture site complications in either National Cardiovascular Data Registry data or institutional electronic health records data. This introduces expanded evidence of safety in decreasing bed rest length in larger (7-French) arterial sheaths post-percutaneous coronary intervention. © 2017 John Wiley & Sons Ltd.

    Patient-reported outcomes (PROs) are valuable for effectiveness evaluation, but it is unknown whether the patient views obtained represent the actual case mix. We studied the representativeness of the responses obtained to a routinely administered health-related quality of life (HRQoL) questionnaire in a cardiology unit. Elective coronary artery bypass grafting (CABG; n = 404) and percutaneous coronary intervention (PCI; n = 738) patients operated during June 2012 to August 2014 in the Heart Center, Kuopio University Hospital. The characteristics of the patients with a baseline (n = 260 and 290 for CABG and PCI, respectively) or both baseline and follow-up HRQoL measurements (n = 203 and 189 for CABG and PCI, respectively) were compared with those who did not respond (n = 144 and 448 for CABG and PCI). Baseline questionnaires were less likely obtained from older CABG patients (odds ratio 0.51, 95% confidence interval 0.28-0.91) and those with more severe disease (0.20, 0.05-0.79). Among PCI patients, women (0.64, 0.45-0.91), smokers (0.74, 0.53-1.04), and those with more severe disease (0.26, 0.13-0.52) or more hospital days were underrepresented. Routinely collected PROs in cardiac patients may be biased towards younger and healthier patients. This needs to be recognized when evaluating the representativeness of such data. The routine collection of these data should be adequately resourced.

    Full Text Available Coronary computed tomography angiography (CCTA has evolved notably over the last decade, gaining an increased amount of temporo-spatial resolution in combination with decreased radiation exposure. The importance of CCTA is emerging especially in vulnerable and young patients who might not have developed a viable collateral vascular network to sustain the circulation to an infarction area during a major adverse coronary event. There are a few well-known markers by which a vulnerable plaque can be assessed and that can predict the subsequent events of sudden myocardial ischemia, such as an increased positive remodeling index (cut-off >1.4, low-attenuation plaque (cut-off 0.7, and napkin-ring sign (NRS. This manuscript presents a series of 3 clinical cases of young patients experiencing symptoms and signs of myocardial ischemia who underwent CCTA in order to assess the composition and functional characteristics of atherosclerotic plaques and their repercussion in developing an acute coronary syndrome.

    Kounis syndrome is an acute coronary syndrome in the context of a hypersensitivity reaction. The main pathophysiological mechanism appears to be coronary vasospasm. We report the case of a patient with a history of allergy to quinolones, who was given ciprofloxacin before an elective surgical procedure and during drug administration developed symptoms and electrocardiographic changes suggestive of ST-segment elevation acute coronary syndrome. The drug was suspended and coronary angiography excluded epicardial coronary disease. Two hours after withdrawal of the drug the symptoms and ST elevation had resolved completely.

    Patients with body integrity identity disorder (BIID) experience a strong desire for amputation from very early on. BIID patients are often dismissed when they share their wish for amputation with surgeons. Consequently, patients resort to self-amputation, including complications and sometimes death. BIID patients are not psychotic and are mentally competent to oversee the consequences of an elective amputation. The authors offer arguments in favor of elective amputation.

    Limitations in the quality and access of cost data from low-income and middle-income countries constrain the implementation of economic evaluations. With the increasing prevalence of coronary artery disease in Malaysia, cost information is vital for cardiac service expansion. We aim to calculate the hospitalisation cost of percutaneous coronary intervention (PCI), using a data collection method customised to local setting of limited data availability. This is a cross-sectional costing study from the perspective of healthcare providers, using top-down approach, from January to June 2014. Cost items under each unit of analysis involved in the provision of PCI service were identified, valuated and calculated to produce unit cost estimates. Five public cardiac centres participated. All the centres provide full-fledged cardiology services. They are also the tertiary referral centres of their respective regions. The cost was calculated for elective PCI procedure in each centre. PCI conducted for urgent/emergent indication or for patients with shock and haemodynamic instability were excluded. The outcome measures of interest were the unit costs at the two units of analysis, namely cardiac ward admission and cardiac catheterisation utilisation, which made up the total hospitalisation cost. The average hospitalisation cost ranged between RM11 471 (US$3186) and RM14 465 (US$4018). PCI consumables were the dominant cost item at all centres. The centre with daycare establishment recorded the lowest admission cost and total hospitalisation cost. Comprehensive results from all centres enable comparison at the levels of cost items, unit of analysis and total costs. This generates important information on cost variations between centres, thus providing valuable guidance for service planning. Alternative procurement practices for PCI consumables may deliver cost reduction. For countries with limited data availability, costing method tailored based on country setting can be used for

    Contrast medium-induced acute kidney injury (CIAKI) is a leading cause of acquired renal impairment. The effects of antioxidants have been conflicting regarding the prevention of CIAKI. We performed a study of vitamin E use to decrease CIAKI in patients undergoing elective coronary angiography. In a placebo-controlled randomized trial at 2 centers in Iran, 300 patients with chronic kidney disease-defined as estimated glomerular filtration rate vitamin E 12 hours before plus 400 mg vitamin E 2 hours before coronary angiography or to receive placebo. The primary end point was the development of CIAKI, defined as an increase ≥0.5 mg/dL or ≥25% in serum creatinine that peaked within 72 hours. Based on an intention-to-treat analysis, CIAKI developed in 10 (6.7%) and 21 (14.1%) patients in the vitamin E and placebo groups, respectively (P=0.037). Change in white blood cell count from baseline to peak value was greater in the vitamin E group compared with the placebo group (-500 [-1500 to 200] versus 100 [-900 to 600]×10(3)/mL, P=0.001). In multivariate analysis, vitamin E (odds ratio 0.408, 95% CI 0.170-0.982, P=0.045) and baseline Mehran score (odds ratio 1.257, 95% CI 1.007-1.569; P=0.043) predicted CIAKI. Prophylactic short-term high-dose vitamin E combined with 0.9% saline infusion is superior to placebo for prevention of CIAKI in patients undergoing elective coronary angiography.

    To determine the frequency of myocardial damage in elective, successful, single vessel percutaneous coronary angioplasty by assessing myocardial band (MB), creatinine kinase levels and to find out the association of common modifiable risk factors with myocardial damage in patients undergoing single vessel coronary angioplasty. Fifty patients undergoing elective and successful single vessel percutaneous coronary angioplasty were evaluated with creatinine kinase and creatinine kinase MB levels before and after 8 hours and 1st day following coronary angioplasty. Studied variables included the length of stent deployed, maximum deployment pressure and total balloon inflation time, apart from hypertension, cholesterol level, smoking and diabetes mellitus. Out of 50 patients, 9 had raised creatinine kinase at 8 hours (18%) and 10 had raised creatinine kinase (20%) on 1st day following coronary angioplasty, 7 (14%) patients and 8 (16%) patients had raised creatinine kinase MB levels at 8 hours and 1st day following coronary angioplasty respectively. The rise of either was equal to or more than 3 times the normal limits. Modifiable risk factors, significantly associated with myocardial damage, were diabetes mellitus (p=0.006) and LDL levels (p=0.009) in patients undergoing single vessel coronary angioplasty. Successful elective, uncomplicated, single vessel coronary angioplasty resulted in some myocardial damage evident by mild rise in cardiac enzymes but rise of creatinine kinase MB above 3 times of normal, which signifies percutaneous coronary angioplasty-related myocardial infarction, was not seen. There was a significant association between diabetes mellitus, LDL levels and myocardial damage in patients undergoing coronary angioplasty but no significant association was found between hypertension, smoking and myocardial damage.

    Objective: To explore the relationship between homocysteine (HCY) and C-reactive protein (CRP) in obstructive sleep apnea/hypopnea syndrome (OSAHS) patients and OSAHS patients complicated with coronary heart disease by detecting the scrum level of HCY and CRP on the mechanism of OSAHS complicated with coronary heart disease. Methods: Ninety-one patients were divided into three groups, 30 patients as control group, 36 patients as OSAHS group, and 25 patients as OSAHS complicated with CHD group. Serum HCY level was detected through chemiluminescence. Serum CRP level was detected through radioimmunity. The serum level of HCY and CRP was compared among these groups. OSAHS patients were divided into mild OSAHS subgroup, moderate OSAHS subgroup and severe OSAHS subgroup. The morbidity rate of CHD and the serum level of HCY and CRP were compared among these subgroups. Meanwhile the parameters of polysomnogram such as activity apnea-hypopnea index (AHI) and blood oxygen saturation (SaO 2 ) were compared between OSAHS group and OSAHS complicated with coronary heart disease group. Results: (1) There was significant difference among the serum level of HCY and CRP of control group, OSAHS group and OSAHS complicated with CHD group (F HCY =15.80, F CRP =19.21, P all HCY =4.74, t CRP =5.14, P all HCY =7.31, t CRP =8.17, P all 2 =6.96, χ 2 =4.18, P HCY =16.38, F CRP =12.97, P all 2 of OSAHS group and OSAHS complicated with CHD group (t AHI =5.46, percentage of SaO 2 2 : t=4.68, average lowest SaO 2 : t=3.65, longest duration of disordered breathing events: t=4.73, P all<0.01 ). Conclusion: The serum level of HCY and CRP rose because of hypoxia in OSAHS patients,and might play an important role in the mechanism of OSAHS complicated with CHD. (authors)

    Full Text Available Abstract Background Many health care systems now use priority wait lists for scheduling elective coronary artery bypass grafting (CABG surgery, but there have not yet been any direct estimates of reductions in in-hospital mortality rate afforded by ensuring that the operation is performed within recommended time periods. Methods We used a population-based registry to identify patients with established coronary artery disease who underwent isolated CABG in British Columbia, Canada. We studied whether postoperative survival during hospital admission for CABG differed significantly among patients who waited for surgery longer than the recommended time, 6 weeks for patients needing semi-urgent surgery and 12 weeks for those needing non-urgent surgery. Results Among 7316 patients who underwent CABG, 97 died during the same hospital admission, for a province-wide death rate at discharge of 1.3%. The observed proportion of patients who died during the same admission was 1.0% (27 deaths among 2675 patients for patients treated within the recommended time and 1.5% (70 among 4641 for whom CABG was delayed. After adjustment for age, sex, anatomy, comorbidity, calendar period, hospital, and mode of admission, patients with early CABG were only 2/3 as likely as those for whom CABG was delayed to experience in-hospital death (odds ratio 0.61; 95% confidence interval [CI] 0.39 to 0.96. There was a linear trend of 5% increase in the odds of in-hospital death for every additional month of delay before surgery, adjusted OR = 1.05 (95% CI 1.00 to 1.11. Conclusion We found a significant survival benefit from performing surgical revascularization within the time deemed acceptable to consultant surgeons for patients requiring the treatment on a semi-urgent or non-urgent basis.

Current standard antithrombotic therapy after coronary stent implantation consists of lifelong aspirin and clopidogrel for a variable period depending in part on the stent type. Despite its well-established efficacy in reducing cardiac-related death, myocardial infarction, and stroke, dual antiplatelet therapy with aspirin and clopidogrel is not without shortcomings. While clopidogrel may be of little beneficial effect if administered immediately prior to PCI and may even increase major bleeding risk if coronary artery bypass grafting is anticipated, early discontinuation of the drug may result in insufficient antiplatelet coverage with thrombotic complications. Optimal and rapid inhibition of platelet activity to suppress ischemic and thrombotic events while minimizing bleeding complications is an important therapeutic goal in the management of patients undergoing percutaneous coronary intervention. In this article we present an overview of the literature on clinical trials evaluating the different aspects of antithrombotic therapy in patients

    Full Text Available Coronary artery perforation is an uncommon complication in patients with coronary heart disease undergoing percutaneous coronary intervention. However, pericardial tamponade following coronary artery perforation may be lethal, and prompt treatment is crucial in managing such patients. Balloon occlusion and the reversal of anticoagulant activity are the common methods used to prevent cardiac tamponade by reducing the amount of bleeding. Herein, we discuss the pros and cons of currently used occlusion types for coronary perforation. Optimal balloon occlusion methods should reduce the amount of bleeding and ameliorate subsequent myocardial ischemia injury, even during cardiac surgery.

    To investigate the incidence of contrast media-induced nephropathy (CIN) in patients with stable coronary artery disease (CAD) referred for elective coronary intervention following hydration routines. The reversibility of CIN was followed in a 6 month-period. A total of 447 patients referred for elective coronary intervention due to suspected CAD were included. Blood samples were collected before and 24 h after intervention and medical records were obtained. Patients had no drinking fluid restrictions and were routinely treated with a 1000 ml saline infusion. All patients were invited to a 6-month examination and collection of blood samples. A total of 19 patients (4.3%) developed CIN. CIN patients had a pre-investigation higher estimated glomerular filtration rate (eGRF), lower level of kidney failure and lower creatinine level than non-CIN patients. Kidney function was not normalized in CIN patients 6 months after the intervention. Two patients still met the definition of CIN. With no restriction in fluid intake and supplementary infusion of saline, only a few patients with stable CAD developed early indications of CIN during elective coronary interventions. Kidney function and the amount of contrast media used was not a predictor of CIN development. The induced CIN was not completely normalized in a 6-month follow-up period.

    Worsening renal function, indicated by increased serum creatinine (SCr), is a common complication of percutaneous coronary procedures. Risk factors for increased SCr overlap with coronary risk factors involved in endothelial dysfunction. We hypothesized that endothelial dysfunction, measured using the reactive hyperemia peripheral arterial tonometry index (RHI), can predict periprocedure-increased SCr. RHI was assessed before elective coronary procedures in 316 consecutive stable patients with a preserved estimated glomerular filtration rate (eGFR, >60mL/min/1.73m 2 ). SCr was measured before and 2 days after procedures. There was no significant correlation between natural logarithmic transformations of RHI (Ln-RHI) and basal Ln-eGFR. Periprocedure increase in SCr was observed in 148 (47%) patients. The increased SCr group had significantly lower Ln-RHI [0.48 (0.36, 0.62) vs. 0.59 (0.49, 0.76), pfunction by RHI is an effective strategy to assess the patient's risk conditions for worsening renal function after percutaneous coronary procedures.

    Background Evidence suggests that high-dose statin pretreatment may reduce the risk of periprocedural myocardial infarction (PMI) and major adverse cardiac events (MACE) for certain patients; however, previous analyses have not considered patients with a history of statin maintenance treatment. In this meta-analysis of randomized controlled trials (RCTs), we reevaluated the efficacy of short-term high-dose statin pretreatment to prevent PMI and MACE in an expanded set of patients undergoing elective percutaneous coronary intervention. Methods We searched the PubMed/Medline database for RCTs that compared high-dose statin pretreatment with no statin or low-dose statin pretreatment as a prevention of PMI and MACE. We evaluated the incidence of PMI and MACE, including death, spontaneous myocardial infarction, and target vessel revascularization at the longest follow-up for each study for subgroups stratified by disease classification and prior low-dose statin treatment. Results Twenty-four RCTs with a total of 5,526 patients were identified. High-dose statin pretreatment was associated with 59% relative reduction in PMI (odds ratio [OR]: 0.41; 95% confidence interval [CI]: 0.34–0.49; Pstatin pretreatment on MACE was significant for statin-naive patients (OR: 0.69; 95% CI: 0.50–0.95; P = 0.02) and prior low dose statin-treated patients (OR: 0.28; 95% CI: 0.12–0.65; P = 0.003); and for patients with acute coronary syndrome (OR: 0.52; 95% CI: 0.34–0.79; P = 0.003), but not for patients with stable angina (OR: 0.71; 95% CI 0.45–1.10; P = 0.12). Long-term effects on survival were less obvious. Conclusions High-dose statin pretreatment can result in a significant reduction in PMI and MACE for patients undergoing elective PCI. The positive effect of high-dose statin pretreatment on PMI and MACE is significant for statin-naïve patients and patients with prior treatment. The positive effect of high-dose statin pretreatment on MACE is significant for

    Introduction Perinatal mortality rates have come down in cesarean sections, but fetal morbidity is still high in comparison to vaginal delivery and the complications are more commonly seen in emergency than in elective cesarean sections. The objective of the study was to compare the fetal outcome and the indications in elective versus emergency cesarean section performed in a tertiary maternity hospital. Methods This comparative cross-sectional prospective study of all the cases undergoing elective and emergency cesarean section for any indication at Souissi maternity hospital of Rabat, Morocco, was carried from January 1, to February 28, 2014. Data were analyzed with emphasis on fetal outcome and cesarean sections indications. Mothers who had definite antenatal complications that would adversely affect fetal outcome were excluded from the study. Results There was 588 (17.83%) cesarean sections among 3297 births of which emergency cesarean section accounted for 446 (75.85%) and elective cesarean section for 142 cases (24.15%). Of the various factors analyzed in relation to the two types of cesarean sections, statistically significant associations were found between emergency cesarean section and younger mothers (P cesarean section performed under general anesthesia (P cesarean section was fetal distress (30.49%), while the most frequent indication in elective cesarean section was previous cesarean delivery (47.18%). Conclusion The overall fetal complications rate was higher in emergency cesarean section than in elective cesarean section. Early recognition and referral of mothers who are likely to undergo cesarean section may reduce the incidence of emergency cesarean sections and thus decrease fetal complications. PMID:27347286

    Introduction of the modified Bentall procedure with the button technique has reduced but not eliminated anastomotic complications in patients receiving a composite aortic conduit. Particularly the true incidence of coronary ostial complications such as stenosis, kinking or pseudoaneurysm formation needs to be assessed. We reviewed 71 patients receiving a composite aortic conduit from November 1993 to November 1999 for chronic aneurysms (n = 51) or aortic dissection (n = 20), 12 of whom had Marfan syndrome. Patients were divided into two groups according to variations in the surgical technique. In group 1 (30 patients; 42%) the classic modified Bentall operation with the button technique was employed whereas in group 2 (41 patients; 58%) some technical modifications were added mainly consisting of a reinforcement suture joining the cut edge of the aortic wall and the prosthetic sewing ring and suture of the coronary buttons with an "endo-button" technique. To detect potential procedure-related complications particularly at the coronary ostia anastomoses follow-up included transthoracic two-dimensional echocardiography every 6 months and computerized tomographic angiography at 12 months or whenever indicated; in 20 patients a magnetic resonance imaging angiography and standard aortography with selective coronary angiography were also added. At a mean follow-up of 49 +/- 19 months anastomotic complications occurred in 4 patients (6%): in 2 a pseudoaneurysm developed at the distal aortic suture line and in 1 a pseudoaneurysm developed at the right coronary ostium after repair of acute aortic dissection; in 1 Marfan patient an aneurysm of the left coronary ostium developed. Such complications were unrelated to the two surgical techniques used in this series for reimplantaion of the coronary ostia. The modified Bentall operation is associated with an extremely low incidence of anastomotic complications particularly at the coronary ostia. More extensive use of new imaging

    Pre-operative assessment is required prior to the majority of elective surgical procedures, primarily to ensure that the patient is fit to undergo surgery, whilst identifying issues that may need to be dealt with by the surgical or anaesthetic teams. The post-operative management of elective surgical patients begins during the peri-operative period and involves several health professionals. Appropriate monitoring and repeated clinical assessments are required in order for the signs of surgical complications to be recognised swiftly and adequately. This article examines the literature regarding pre-operative assessment in elective orthopaedic surgery and shoulder surgery, whilst also reviewing the essentials of peri- and post-operative care. The need to recognise common post-operative complications early and promptly is also evaluated, along with discussing thromboprophylaxis and post-operative analgesia following shoulder surgery.

A retrospective study for a period of 5 years in general surgery department, Habib Bourguiba hospital, Sfax, including all patients operated with confection of a colostomy. Were then studied patients reoperated for stoma complication. Among the 268 patients who have had a colostomy, 19 patients (7%) developed surgical stoma complications. They had a mean age of 59 years, a sex ratio of 5.3 and a 1-ASA score in 42% of cases. It was a prolapse in 9 cases (reconfection of the colostomy: 6 cases, restoration of digestive continuity: 3 cases), a necrosis in 5 cases (reconfection of the colostomy), a plicature in 2 cases (reconfection of the colostomy) a peristomal abscess in 2 cases (reconfection of the colostomy: 1 case, restoration of digestive continuity: 1 case) and a strangulated parastomal hernia in 1 case (herniorrhaphy). The elective incision and the perineal disease were risk factors for the occurrence of prolapse stomial. Surgical complications of colostomies remain a rare event. Prolapse is the most common complication, and it is mainly related to elective approach. Reoperation is often required especially in cases of early complications, with usually uneventful postoperative course.

    After coronary angiography to prevent potential complications, patients are restricted to 4-24 hours bed rest in the supine position due to the complications. This study was designed to assess the effect of changing position and early ambulation on low back pain, urinary retention, bleeding and hematoma after cardiac catheterization. In this clinical trial, 140 patients by using a convenience sampling randomly divided into four 35-individual groups. The patients in the control group were in the supine position for 6 hours without a movement. Change position was applied to the second group (based on a specific protocol), early ambulation was applied to the third group and both early ambulation and change position were applied to the fourth group. Then, severity of bleeding, hematoma, back pain and urinary retention were measured at zero, 1, 2, 4, 6, and 24 hours after angiography. The data was collected through an individual data questionnaire, Numerical Rating Scale (NRS) of pain and Kristin Swain's check list was applied to evaluate the severity of bleeding and hematoma. None of patients developed vascular complications. Incidence of urinary retention was higher in the control group, although this difference was not significant. The mean of pain intensity in the fourth and sixth hours showed a significant difference. Based on the findings of this study, changing patients' position can be safe and they can be ambulated early after angiography.

    Full Text Available Background/Aim. Despite recent advances in coronary artery bypass grafting (CABG, cardioplegic cardiac arrest and cardiopulmonary bypass (CPB are still associated with myocardial injury. Accordingly, the efforts have been made lately to improve the outcome of CPB by glucose-insulinpotassium, adenosine, Ca2+-channel antagonists, L-arginine, N-acetylcysteine, coenzyme Q10, diazoxide, Na+/H+ exchange inhibitors, but with an unequal results. Since omega-3 polyunsatutated fatty acids (PUFAs have shown remarkable cardioprotection in preclinical researches, the aim of our study was to check their effects in prevention of ischemia reperfusion injury in patients with CPB. Methods. This prospective, randomized, placebo-controlled study was performed with parallel groups. The patients undergoing elective CABG were randomized to receive preoperative intravenous omega-3 PUFAs infusion (n = 20 or the same volume of 0.9% saline solution infusion (n = 20. Blood samples were collected simultaneously from the radial artery and the coronary sinus before starting CPB and at 10, 20 and 30 min after the release of the aortic cross clamp. Lactate extraction/excretion and myocardial oxygen extraction were calculated and compared between the two groups. The levels of troponin I (TnT and creatine kinase-myocardial band (CK-MB were determined before starting CPB and 4 and 24 h postoperatively. Results. Demographic and operative characteristics, including CPB and aortic cross-clamp time, were similar between the two groups of patients. The level of lactate extraction 10 and 20 min after aortic cross-clamp time has shown negative values in the control group, but positive values in the PUFAs group with statistically significant differences (-19.6% vs 7.9%; p < 0.0001 and -19.9% vs 8.2%; p < 0.0008, respectively. The level of lactate extraction 30 minutes after reperfusion was not statistically different between the two groups (6.9% vs 4.2%; p < 0.54. Oxygen extraction in the

    The aim of our study was to investigate the association between history of depressive episode and anxiety and complications in patients after 6 months of coronary artery angioplasty. The research was conducted on 70 patients, the grade of coronary occlusion that would not respond to therapeutic treatment and need coronary angioplasty had been established. Complications were estimated in 60 patients after 6 months of coronary angioplasty. To evaluate depression we used Beck depression scale Anxiety was assessed by Spilberger State-trait anxiety scale. Statistic analysis of the data was made by means of the methods of variation statistics using Students' criterion and program of STATISTICA w 5.0. Complications were discovered in 36 (60%) patients; 24 (40%) patients had not complications. There was not revealed significant statistical differences in depression and anxiety degree in coronary angioplasty period and after 6 months of coronary angioplasty. There was not revealed significant statistical differences in depression and anxiety degree in coronary angioplasty period and after 6 months of coronary angioplasty. Our study demonstrated that complications were revealed in patients who had high degree of depression and anxiety.

  10. Prevention of cardiac complications in peripheral vascular surgery

    The prevalence of severe coronary artery disease in peripheral vascular patients exceeds 50 per cent. Complications of coronary artery disease are the most common causes of mortality following peripheral vascular operations. To reduce the incidence of cardiac complications, it is first necessary to identify patients at risk through screening tests. Screening methods in current use include risk factor analysis, exercise testing, routine coronary angiography, and dipyridamole thallium-201 scintigraphy. The risk factor approach has the advantage of being widely applicable since it makes use of historical, physical, and electrocardiographic findings that are already familiar to surgeons and anesthesiologists. It is also inexpensive. However, it may overlook the patient who has no symptoms of coronary artery disease, possibly as a result of the sedentary lifestyle imposed by complications of peripheral vascular disease. The electrocardiographically monitored stress test will identify the asymptomatic patient with occult coronary disease and is helpful in predicting operative risk. However, a meaningful test is dependent on the patient's ability to exercise--an activity that is frequently limited by claudication, amputation, or arthritis. Exercise testing also suffers from a lack of sensitivity and specificity when compared with coronary arteriography. Routine preoperative coronary angiography overcomes the exercise limitation of treadmill testing but is not widely applicable as a screening test for reasons of cost and inherent risk. Dipyridamole thallium-201 scanning, on the other hand, is safe and of relatively low cost and does not require exercise

    Full Text Available Introduction: After coronary angiography to prevent potential complications, patients are restricted to 4-24 hours bed rest in the supine position due to the complications. This study was designed to assess the effect of changing position and early ambulation on low back pain, urinary retention, bleeding and hematoma after cardiac catheterization. Methods: In this clinical trial, 140 patients by using a convenience sampling randomly divided into four 35-individual groups. The patients in the control group were in the supine position for 6 hours without a movement. Change position was applied to the second group (based on a specific protocol, early ambulation was applied to the third group and both early ambulation and change position were applied to the fourth group. Then, severity of bleeding, hematoma, back pain and urinary retention were measured at zero, 1, 2, 4, 6, and 24 hours after angiography. The data was collected through an individual data questionnaire, Numerical Rating Scale (NRS of pain and Kristin Swain’s check list was applied to evaluate the severity of bleeding and hematoma. Results: None of patients developed vascular complications. Incidence of urinary retention was higher in the control group, although this difference was not significant. The mean of pain intensity in the fourth and sixth hours showed a significant difference.Conclusion: Based on the findings of this study, changing patients’ position can be safe and they can be ambulated early after angiography.

    Objective: To evaluate the practicability and safety of the percutaneous transbrachial approach (TBA) for diagnostic coronary angiography and therapeutic percutaneous coronary interventions. Study Design: Quasi experimental study. Place and Duration of Study: The study was carried out in Armed Forces Institute of Cardiology- National Institute of Heart Diseases (AFIC-NIHD) from March 2009 to May 2011. Patients and Methods: We collected data of 100 consecutive patients who underwent coronary catheterization by the percutaneous transbrachial approach. Transbrachial catheterization was performed only if the radial access failed or radial pulse was feeble. Study endpoints included successful brachial artery catheterization, vascular and neurological complications at access site and procedure success rate. Results: Mean age of the patients was 54 years (range 33-79 yrs) and 65(65%) were males and 35 (35%) were females. The right brachial artery was used in all of the cases. Procedural success was achieved in 100% of the patients. Coronary angiography was performed in 70 patients and percutaneous coronary interventions were done in 30 cases. Out of these 30 cases, PCI to left coronary arteries (LAD and LCX) were performed in 19 patients while 11 patients had PCI to right coronary artery (RCA). No case of vascular complications such as major access site bleeding, vascular perforation, brachial artery occlusion causing forearm ischemia, compartment syndrome, vascular spasm or failure to catheterize coronary arteries requiring alternate vascular access were observed. Conclusion: Brachial artery is a safe and easily accessible approach for coronary angiography and percutaneous coronary interventions. (author)

    OBJECTIVE: To quantify the effects of fenoldopam, 0.1 microg\\/kg\\/min, on left internal mammary artery (LIMA) and saphenous vein blood flow after coronary anastomosis. DESIGN: Prospective, randomized, double-blind, placebo-controlled trial. SETTING: University teaching hospital, single institution. PARTICIPANTS: Thirty-one American Society of Anesthesiologists III patients undergoing elective coronary revascularization. INTERVENTIONS: A perivascular ultrasonic flow probe (Linton Instrumentation, Norfolk, UK) was placed around the LIMA and saphenous vein graft after coronary anastomosis. MEASUREMENTS AND MAIN RESULTS: Immediately before and at 5-minute intervals for 15 minutes after starting the infusion, blood flow was measured in the LIMA and one saphenous vein graft using a transit time ultrasonic flow probe. Heart rate, blood pressure, and central venous pressure were documented at these time points. Administration of fenoldopam, 0.1 microg\\/kg\\/min, did not alter heart rate or blood pressure. A small, nonsignificant increase in LIMA blood flow occurred during the 15-minute study period (30 +\\/- 12 to 35 +\\/- 10 mL\\/min) in patients who received fenoldopam. No significant changes occurred in the placebo group. CONCLUSIONS: The findings indicate that fenoldopam, 0.1 microg\\/kg\\/min, did not influence coronary conduit blood flow to a clinically significant extent. The small increase in LIMA blood flow may be of greater importance in high-risk patients or in the prevention of coronary arterial spasm.

    The role of laparoscopic surgery in the management of patients with diverticular disease is still not universally accepted. The aim of our study was to evaluate the results of laparoscopic surgery for diverticular disease in a centre with a specialist interest in minimally invasive surgery. All diverticular resections carried out between 2006 and 2010 were reviewed. Data recorded included baseline demographics, indication for surgery, operative details, length of hospital stay and complications. Complicated diverticular disease was defined as diverticulitis with associated abscess, phlegmon, fistula, stricture, obstruction, bleeding or perforation. One hundred and two patients (58 men) who had surgery for diverticular disease were identified (median age 59 years, range 49-70 years). Sixty-four patients (64%) had surgery for complicated diverticular disease. The indications were recurrent acute diverticulitis (37%), colovesical fistula (21%), stricture formation (17%) and colonic perforation (16%). Sixty-nine cases (88%) were completed by elective laparoscopy. Postoperative mortality was 0%. For elective cases there was no difference in morbidity rates between patients with complicated and uncomplicated diverticular disease. The overall anastomotic leakage rate was 1% and the wound infection rate 7%. There was a nonsignificant trend to higher conversion to open surgery in the elective group in complicated (11.4%) compared with uncomplicated patients (5.2%) (P=0.67). Electively, the rate of stoma formation was higher in the complicated (31.6%) than the uncomplicated group (5.2%) (Pdiverticular disease is associated with low rates of postoperative morbidity and relatively low conversion rates.

    Acute heart failure and/or cardiogenic shock are frequently triggered by ischemic coronary events. Yet, there is a paucity of randomized data on the management of patients with heart failure complicating acute coronary syndrome, as acute coronary syndrome and cardiogenic shock have frequently been defined as exclusion criteria in trials and registries. As a consequence, guideline recommendations are mostly driven by observational studies, even though these patients have a particularly poor prognosis compared to heart failure patients without signs of coronary artery disease. In acute heart failure, and especially in cardiogenic shock related to ischemic conditions, vasopressors and inotropes are used. However, both pathophysiological considerations and available clinical data suggest that these treatments may have disadvantageous effects. The inodilator levosimendan offers potential benefits due to a range of distinct effects including positive inotropy, restoration of ventriculo-arterial coupling, increases in tissue perfusion, and anti-stunning and anti-inflammatory effects. In clinical trials levosimendan improves symptoms, cardiac function, hemodynamics, and end-organ function. Adverse effects are generally less common than with other inotropic and vasoactive therapies, with the notable exception of hypotension. The decision to use levosimendan, in terms of timing and dosing, is influenced by the presence of pulmonary congestion, and blood pressure measurements. Levosimendan should be preferred over adrenergic inotropes as a first line therapy for all ACS-AHF patients who are under beta-blockade and/or when urinary output is insufficient after diuretics. Levosimendan can be used alone or in combination with other inotropic or vasopressor agents, but requires monitoring due to the risk of hypotension. Copyright © 2016 The Authors.

    Full Text Available Tranexamic acid is now used on a routine basis for on-pump coronary artery bypass grafting (CABG. We assessed the hemostatic effects of tranexamic acid to decrease bleeding tendency and transfusion requirements in patients undergoing off-pump coronary artery bypass surgery (OPCAB. A total of 66 patients were enrolled to elective OPCAB in a double-blind, prospective randomized study. Of these, 33 patients received tranexamic acid (15 mg/kg before the infusion of heparin and 15 mg/kg after protamin infusion, and 33 patients received only saline. Preoperative hematologic variables, postoperative bleeding and allogeneic transfusions were considered. D-dimer plasma levels were also evaluated to monitor the activation of fibrinolysis. Postoperative bleeding was significantly lower in the tranexamic acid group compared with the control group (320 ± 38 mL vs. 480 ± 75 mL at 12 hour, P < 0.001. The tranexamic acid group had significantly lesser need for allogeneic blood products (0.46 units/patients vs. 0.94 units/patients, P < 0.001. They had also lower post-operative D-dimer plasma levels. No postoperative thrombotic complications were observed in either group. The defective hemostasis occurs even in the OPCABG. Tranexamic acid effectively reduces postoperative blood loss and the need for allogeneic blood products after OPCAB is decreased.

    In the 2008 U.S. presidential election, social network sites such as Facebook allowed users to share their political beliefs, support specific candidates, and interact with others on political issues. But do political activities on Facebook affect political participation among young voters, a group traditionally perceived as apathetic in regard to civic engagement? Or do these activities represent another example of feel-good participation that has little real-world impact, a concept often referred to as "slacktivism"? Results from a survey of undergraduate students (N = 683) at a large public university in the Midwestern United States conducted in the month prior to the election found that students tend to engage in lightweight political participation both on Facebook and in other venues. Furthermore, two OLS regressions found that political activity on Facebook (e.g., posting a politically oriented status update, becoming a "fan" of a candidate) is a significant predictor of other forms of political participation (e.g., volunteering for an organizing, signing a paper or online petition), and that a number of factors--including intensity of Facebook use and the political activity users see their friends performing on the site--predict political activity on Facebook. Students' perceptions regarding the appropriateness of political activity on Facebook, as well as the specific kinds of political activities they engaged in and witnessed within the site, were also explored.

    Full Text Available BackgroundThe early warning scores may increase the safety of perioperative period. The objective of this study was to assess the diagnostic and predictive role of Integrated Pulmonary Index (IPI after off-pump coronary artery bypass grafting (OPCAB.Materials and MethodsForty adult patients undergoing elective OPCAB were enrolled into a single-center prospective observational study. We assessed respiratory function using IPI that includes oxygen saturation, end-tidal CO2, respiratory rate, and pulse rate. In addition, we evaluated blood gas analyses and hemodynamics, including ECG, invasive arterial pressure, and cardiac index. The measurements were performed after transfer to the intensive care unit, after spontaneous breathing trial and at 2, 6, 12, and 18 h after extubation.Results and DiscussionThe value of IPI registered during respiratory support correlated weakly with cardiac index (rho = 0.4; p = 0.04 and ScvO2 (rho = 0.4, p = 0.02. After extubation, IPI values decreased significantly, achieving a minimum by 18 h. The IPI value ≤9 at 6 h after extubation was a predictor of complicated early postoperative period (AUC = 0.71; p = 0.04 observed in 13 patients.ConclusionIn off-pump coronary surgery, the IPI decreases significantly after tracheal extubation and may predict postoperative complications.

    Clopidogrel has become standard treatment after urgent percutaneous coronary revascularization. Due to its enhanced and irreversible platelet inhibition, patients undergoing urgent surgical revascularization have a higher risk of bleeding complications and transfusions. Therefore, the effect of preoperative continuous administration of clopidogrel on the incidence of hemorrhagic complications in patients undergoing off-pump coronary artery bypass surgery with acute coronary syndrome was evaluated. From March 2004 to September 2006, 172 patients with acute coronary syndrome underwent isolated off-pump coronary artery bypass surgery; 70 (40.7%) and 102 (59.3%) of these patients did or did not take clopidogrel before surgery respectively. Seventy patients in each group were matched using propensity scores and associations between preoperative continuous administration of clopidogrel and postoperative bleeding, hemostatic reoperation, blood products received, the need for multiple transfusions and early graft patency by coronary computed tomography were assessed. Univariate analysis showed the continuous clopidogrel group had similar levels of postoperative bleeding for 24 h (601.4±312.6 ml vs 637.2±452.4 ml, p=0.616) and rates of reexploration (1.4% vs 1.4%), perioperative blood transfusion (33.3% vs 34.3%, p>0.05) and platelet transfusion (2.9% vs 7.1%, p=0.44) compared with the non-continuous group. Preoperative continuous administration of clopidogrel did not increase the risk of hemorrhagic complications in patients with acute coronary syndrome undergoing isolated off-pump coronary artery bypass surgery. These findings indicate that surgery after clopidogrel treatment in patients with acute coronary syndrome should not be delayed until platelet function returns to normal because they may have a higher risk of recurrent myocardial ischemic events.

    Full Text Available Background: Long-term adverse cardiovascular effects of smokeless tobacco are well established, however, the effect of chewing tobacco on coronary microcirculation and hemodynamic have not been studied. We intended to analyze the acute effect of chewing tobacco on coronary microcirculation and hemodynamics in habitual tobacco chewers with stable coronary artery disease undergoing elective percutaneous coronary intervention (PCI. Materials and Methods: We prospectively enrolled seven habitual tobacco chewers with stable coronary artery disease with single vessel disease or double vessel disease satisfying the criteria for elective PCI. Patients were instructed to keep 1 g of crushed dried tobacco leaves in the mouth after a successful PCI. Lesion in last stented vessels was evaluated for fractional flow reserve (FFR, coronary flow reserve (CFR, and index of microcirculatory resistance (IMR post-PCI, after 15 min and 30 min of tobacco chewing along with the measurement of serum cotinine levels. Results: Oral tobacco led to high levels of cotinine in the majority of patients. There was an insignificant rise in heart rate, systolic and diastolic blood pressure following tobacco consumption. Baseline CFR (median 1.6, range 1.1–5.5 was low in tobacco chewers after PCI even after optimum FFR (0.9 ± 0.05 in the majority of patients suggesting abnormal microvascular hemodynamics (high IMR in 3 patients, overall median 14.2, range 7–36.2. However, there was no significant change in the estimated CFR or IMR values following tobacco chewing. One patient had bradycardia and hypotension which may be related to vagal reaction or acute nicotine poisoning. Conclusion: Tobacco chewers have abnormal coronary microcirculation hemodynamics even following a successful PCI. However, the coronary micocirculation and hemodynamics do not change acutely following tobacco chewing despite high serum cotinine concentrations.

    Full Text Available Cardiopulmonary bypass is known to elicit systemic inflammatory response syndrome and organ dysfunction. This can result in pulmonary dysfunction and deterioration of oxygenation after cardiac surgery and cardiopulmonary bypass. Previous studies have reported varying results on anti-inflammatory strategies and oxygenation after cardiopulmonary bypass. Ketamine administered as a single dose at induction has been shown to reduce the pro-inflammatory serum markers in patients undergoing cardiopulmonary bypass. Therefore we investigated if ketamine can result in better oxygenation in these patients. This was a prospective randomized blinded study. Eighty consecutive adult patients undergoing elective coronary artery bypass grafting under cardiopulmonary bypass were included in the study. Patients were divided into two groups. Patients in ketamine group received 1mg/kg of ketamine intravenously at induction of anesthesia. Control group patients received an equal volume of saline. All patients received standard anesthesia, operative and postoperative care.Paired t test and independent sample t test were used to compare the inter-group and between group oxygenation indices respectively. Oxygenation index and duration of ventilation were analyzed. Deterioration of oxygenation index was noted in both the groups after cardiopulmonary bypass. However, there was no significant difference in the oxygenation index at various time points after cardiopulmonary bypass or the duration of ventilation between the two groups. This study shows that the administered as a single dose at induction does not result in better oxygenation after cardiopulmonary bypass.

    Introduction Defunctioning loop ileostomy (LI) and loop colostomy (LC) are used widely to protect/treat anastomotic leakage after colorectal surgery. However, it is not known which surgical approach has a lower prevalence of surgical complications after low anterior resection for rectal carcinoma (LARRC). Methods We conducted a literature search of PubMed, MEDLINE, Ovid, Embase and Cochrane databases to identify studies published between 1966 and 2013 focusing on elective surgical complications related to defunctioning LI and LC undertaken to protect a distal rectal anastomosis after LARRC. Results Five studies (two randomized controlled trials, one prospective non-randomized trial, and two retrospective trials) satisfied the inclusion criteria. Outcomes of 1,025 patients (652 LI and 373 LC) were analyzed. After the construction of a LI or LC, there was a significantly lower prevalence of sepsis (p=0.04), prolapse (p=0.03), and parastomal hernia (p=0.02) in LI patients than in LC patients. Also, the prevalence of overall complications was significantly lower in those who received LIs compared with those who received LCs (p<0.0001). After closure of defunctioning loops, there were significantly fewer wound infections (p=0.006) and incisional hernias (p=0.007) in LI patients than in LC patients, but there was no significant difference between the two groups in terms of overall complications. Conclusions The results of this meta-analysis show that a defunctioning LI may be superior to LC with respect to a lower prevalence of surgical complications after LARRC.

    Transarterial chemoembolization has been widely used to treat unresectable hepatocellular carcinoma. Various complications have been reported, but they have not included acute myocardial infarction. Acute myocardial infarction results mainly from coronary artery occlusion by plaques that are vulnerable to rupture or from coronary spasm, embolization, or dissection of the coronary artery. It is associated with significant morbidity and mortality. We present a case report that describes a patient with hepatocellular carcinoma who underwent transarterial chemoembolization and died subsequently of acute myocardial infarction. To our knowledge, there has been no previous report of this complication induced by transarterial chemoembolization for hepatocellular carcinoma. This case illustrates the need to be aware of acute myocardial infarction when transarterial chemoembolization is planned for the treatment of hepatocellular carcinoma, especially in patients with underlying coronary artery disease.

    Malnutrition is known to independently affect patient outcomes. The aim of this study was to investigate the prevalence of patients at risk for malnutrition in an elective surgery patient cohort and to analyze the effects of malnutrition on morbidity, mortality, and hospital length of hospital (LOS). Furthermore, we aimed to evaluate the economic effect of a diligent coding of malnutrition, as a side diagnosis, in a simulation of the German Diagnosis-Related Group system. The nutritional status of 1244 patients undergoing elective surgery was standardized on the day of admission by the Nutritional Risk Screening (NRS) 2002. To quantify the influence of malnutrition on revenue, the real DRGs of all patients were grouped. In simulation, an appropriate International Classification of Diseases code was used as a secondary diagnosis for all malnourished patients based on the NRS rating. A multivariate logistic regression analysis and a Cox regression were performed to identify potential confounders and to determine the adjusted effect of nutritional status on the occurrence of complications and hospital LOS. The prevalence of patients at risk for malnutrition (NRS ≥3) was 24.1% (300 of 1244). These patients showed a significant increase in hospital LOS (13 versus 7 d). Additionally, postoperative complications were significantly higher in this group (7.23% versus 6.91%). Including malnutrition in the Diagnosis-Related Group coding system resulted in a reimbursement of €1979.67 per patient at risk for malnutrition and a total reimbursement of €79,186.73 for all patients at risk for malnutrition in the present study. Establishment of a structured, comprehensive assessment of the nutritional status of hospitalized patients can repetitiously identify patients at risk for malnutrition. Additionally, the diligent codification of malnutrition can lead to cost compensation in the German Diagnosis-Related Group system. Copyright © 2016 Elsevier Inc. All rights reserved.

    Bupivacaine is a long-acting local anesthetic (LA) used for cutaneous infiltration, peripheral nerve blocks, epidural and spinal anesthesia. However, its application may result in cardiovascular complications such as: hypotension, bradycardia, cardiac arrest and toxic myocardial injury. The authors describe a 53-year-old male with a history of cigarette smoking, admitted for an elective inguinal hernia surgery. Before surgery, the patient received subarachnoid injection of bupivacaine (20 mg). After the operation, he developed transient hypotension. Blood pressure returned to normal after gelofusine infusion; no sympathomimetics were administered. The male denied chest pain; however, ECG showed ST segment elevation coexisting with left ventricular anterolateral hypokinesia and decreased longitudinal strain in echocardiography. A significant increase in troponin I level was suggestive rather of myocardial infarction than of takotsubo cardiomyopathy. Urgent coronary angiography revealed left anterior descending artery spasm, which remitted after intracoronary nitroglycerin injection. Normalization of ECG and echocardiography was observed within a few days. The authors indicate that the presented atypical adverse effect of bupivacaine manifested itself with delay and that coronary spasm proceeded without angina. A close observation of the patient after anesthetic procedure with LA should be extended over the postoperative period.

    The lack of a specific counteragent to bivalirudin may complicate the management of patients with coronary artery (CA) perforation during percutaneous coronary intervention (PCI). Assess outcomes of patients with CA perforation from three PCI trials comparing intravenous bivalirudin with provisional glycoprotein (GP) IIb/IIIa inhibition versus unfractionated heparin (UFH) plus GP IIb/IIIa. A pooled analysis of patients treated with PCI in three randomized trials including REPLACE-2, ACUITY, and HORIZONS-AMI. Among a total of 12,921 patients, CA perforation occurred in 35 patients (0.27%). By multivariable analysis, baseline creatinine clearance was the only independent predictor of CA perforation (per 10 mL/min decrease, odds ratio [95% confidence interval]= 1.28 [1.11, 1.47], P = 0.0007). At 30 days, patients with versus without CA perforation had significantly (all P values therapy of bivalirudin monotherapy was not associated with worse outcomes compared to treatment with UFH plus GP IIb/IIIa inhibitors.

    To establish the associations and prognostic utility of angiographic, clinical and HRV parameters in a large cohort of patients undergoing diagnostic cardiac catheterisation (CC). Patients undergoing CC as elective day cases were enrolled at a single tertiary center from September 2001 to January 2003. Patient data, serum biochemistry, current drug therapy, catheter reports and five minute high resolution electrocardiograph (ECG) recordings were prospectively recorded and validated in an electronic archive. ECG recordings were used to generate time domain (SDNN (standard deviation of NN intervals)) and spectral HRV parameters (low frequency (LF) and high frequency (HF) power). Significant associations between dichotomized HRV variables and covariates were investigated using binary logistic regression. The independent prognostic ability of clinical markers was evaluated using the Cox proportional hazard model. 841 consecutive consenting patients of mean age 61+/-10 years were recruited into the study with a mean follow-up period of 690+/-436 days. In multivariate analysis decreasing LF spectral power was independently associated with proximal right coronary stenosis OR (odds ratio)=1.65 (95% CI=1.16-2.36), P=0.006 and to all cause mortality OR=5.01 (95% CI=1.47-17.01), P=0.010. Increasing LF power was also independently associated with normal coronary angiograms in patients investigated suspected coronary disease without a confirmed prior history of a coronary ischaemic event OR=2.16 (95% CI=1.26-3.73), P=0.002. Reduced LF power independently predicts all cause mortality in a large cohort of patients receiving medical therapy after elective CC. LF power was also independently associated with >75% proximal RCA stenosis.

    The aim of this study is to evaluate the difference in perioperative complication rate in total hip, bipolar hemiarthroplasties and total knee arthroplasty in patients with Parkinson disease in trauma and elective surgery in our Musculoskeletal Center during a period of 10 years. Between 2006 and 2016, 45 bipolar hemiarthroplasties in trauma surgery, 15 total knee and 19 total hip arthroplasties in patients with Parkinson's disease were performed. We divided the patients in two groups. Group I included trauma cases (45) and group II elective surgery cases (34). Complications were documented and divided into local minor and major complications and general minor and major complications. Fisher's exact test was used for statistical evaluation. In both groups, there was one local major complication (p > 0.05): In group I, there was one case of loosening of a K-wire which was removed operatively. In group II, there was one severe intraarticular bleeding requiring puncture of the hematoma. In group I, there were 38 general complications; in group II, there were 17 general complications. There was no statistical difference in complication rate (p > 0.05). Total hip arthroplasty, bipolar hemiarthroplasties and knee arthroplasty in patients with Parkinson disease is possible in elective and trauma surgery. Complication rate is higher in comparison with patients not suffering from Parkinson disease, but there is no difference in complication rate in elective and trauma surgery. Nevertheless, early perioperative neurological consultation in patients with Parkinson disease is recommended to minimize complications and improve early outcomes after arthroplasty.

    2013-06-01

    A coronary artery anomaly characterized by the presence of a single left coronary ostium with absence of the right coronary ostium and an anomalous prepulmonic right coronary artery course was observed in two dogs with concurrent congenital pulmonary valve stenosis. This unique coronary artery anatomy is similar to the previously described single right coronary ostium with anomalous prepulmonic left coronary artery, the so-called type R2A anomaly, in that an anomalous coronary artery encircles the pulmonary valve annulus. Both dogs of this report, a boxer and an English bulldog, were of breeds known to be at risk for the type R2A anomaly. As such, veterinarians should be aware that the echocardiographic presence of a left coronary ostium in a dog with pulmonary valve stenosis does not exclude the possibility of a prepulmonic coronary artery anomaly that may enhance the risk of complications during balloon pulmonary valvuloplasty. A descriptive naming convention for coronary artery anomalies in dogs is also presented, which may be preferable to the older coding classification scheme. Copyright © 2013 Elsevier B.V.

    Full Text Available JCMSBackground and Objectives: Tracheostomy is electively performed in critically ill patients requiring prolonged respiratory support. The risk of transporting, the increasing associated cost and operative room schedule are some of the obstacles for wider acceptance of this procedure. The use of rigid selection criteria exclude many patients who would benefit of this approach. The present study was designed to determine the safety of open bedside tracheostomy (OBT as a routine intensive care units (ICU procedure without any selection criteria, considering its peri and postoperative complications.Materials & Methods: Retrospective medical chart review of all patients that underwent elective tracheostomy between June 2014 and January 2015.Results: The study group comprised 52 patients with a mean age of 40.4±15.1 years. The incidence of intra-procedure complications was 5.7% and post-procedure complications was 3.8%.Conclusions: Open bedside tracheostomy seems to be a safe and simple procedure, even when performed by a trained resident under controlled circumstances, and should be considered as an option for ICU patients.JCMS Nepal. 2015;11(1: 9-11

    Full Text Available The study focuses on the tactics of transfusion therapy during coronary artery bypass surgery with cardiopulmonary bypass in patients with left ventricular ejection fraction higher or lower than 40%. To predict the tactics of intraoperative transfusion therapy, hypoxic tests were preoperatively conducted in the main group of patients. A traditional approach to blood transfusion was applied in the control group of patients. The analysis of clinical and laboratory data, hemodynamics and oxygen balance, as well as follow-up data allowed to prove the possibility of decreasing allogenic blood use by 48.8% (p = 0,02. Based on the hypoxic test data, criteria for lowering the intraoperative trigger hemoglobin level down to 70 g/l, including the patients with a low left ventricular ejection fraction. It was shown that our tactics of trigger hemoglobin level calculation allows for reducing artificial lung ventilation time, frequency of gastrointestinal complications, multiple organ failure, as well as duration of stay at ICU.

    Objective: To investigate the significance of changes of serum IL-6, TNF-α, hs-CRP levels in development of coronary heart disease in patients with type 2 diabetes mellitus. Methods: Serum IL-6, TNF-α (with RIA). hs-CRP (with CLIA) and FPG, TG, cholesterol (with biochemistry) contents were measured in (1) DM2 patients complicated with CHD, n=40 and (2) DlVI2 patients without CHD, n=48. Results: The BMI and FPG, TG levels were significantly higher in patients complicated with heart disease than those in patients without CHD (P<0.05) with the exception of cholesterol. The levels of IL-6, TNF-α and hs-CRP were also significantly higher in patients with heart disease than those in patients without heart disease (P<0.05). Conclusion: The high levels of IL-6, TNF-α and hs-CRP played important role in the development of coronary heart disease. Monitoring those levels might be helpful in assessment of treatment efficacy and outcome prediction. (authors)

    Full Text Available A patient developed hemopericardium shortly after left brachial arterial embolectomy using an embolectomy catheter. Evaluation disclosed evolving pseudoaneurysm of the right coronary artery that was successfully managed by stenting. Misplacement of the embolectomy catheter within the coronary vessel was facilitated by an anomalous origin of the right coronary artery. This complication highlights the importance of correct insertion of the embolectomy catheter using the markers to avoid maladvancement and damage to central vessels.

  5. Nigerian Election Management Bodies and their Associated Election Challenges

    2018-01-01

    Full Text Available The paper examined the challenges that confront Election Management Bodies (EMBs in conducting free and fair elections in Nigeria. It aligns with the position of extant literature on the subject that elections in Nigeria have been anything but free and fair, and argues that all the EMBs that have so far conducted elections in Nigeria are complicit in perpetrating electoral malpractices. In other words, though there are external factors that undermine the conduct of free, fair and credible elections in Nigeria, EMBs in Nigeria also present themselves as willing tools in the hands of politicians to compromise the integrity of the electoral process. The number of litigations and level of both international and local denunciations that attend every election in Nigeria underscores the magnitude of electoral malfeasance inherent in the elections conducted by successive EMBs in Nigeria. The paper analysed the major challenges that inhibit the conduct of free and fair elections in Nigeria and proffered solutions to them. Relying heavily on the documentary methods of data collection, the paper concludes that until all these challenges confronting EMBs in Nigeria in the conduct of free and fair elections are comprehensively addressed, credible elections will continue to be a mirage in the country.

    Full Text Available Abstract Coexistence of coronary artery disease and cancer with both requiring surgical treatment at the same time is rare. A 52 year male undergoing elective coronary artery bypass grafting was incidentally discovered to have a large soft tissue mass of variable consistency with cartilaginous elements arising from the right costal margin and adjoining ribs by a broad attachment and protruding into right pleural cavity. Frozen section suggested it to be either a chondrosarcoma or a teratoma. A wide excision of the mass with the adjoining muscle and periosteum along with quadruple coronary artery bypass grafting was done. This report is unusual on account of a being the first reported case in world literature of concomitant excision of chondrosarcoma and coronary artery bypass grafting and b the conservative management of the incidentally discovered chondrosarcoma by wide excision rather than chest wall resection with no local recurrence to date. Pathology of chondrosarcoma, in particular, and various management strategies when coronary artery disease and cancer coexist, in general, is discussed.

    To compare the results of isobaric bupivacaine (0.5%) with hyperbaric bupivacaine (0.75%) in cases of elective Caesarean Section, in respect of time to sensory analgesia, highest level of sensory block, haemodynamic effects, and complications. Sixty pregnant patients scheduled for elective Caesarean Section. The patients were randomly assigned to receive either 0.5% isobaric bupivacaine (Group-1B) or 0.75% hyperbaric bupivacaine (Group-HB) via intrathecal route. The time of onset of block, highest level of sensory block, cardio-respiratory data, duration of analgesia and complications were recorded during surgery. The time taken to reach T4 sensory analgesia in Group-1B was 6+-6.43 minutes as compared to 6.93+-7.8 minutes in Group-HB, while the highest sensory level achieved in Group-1B was T1 and in Group-HB T2. The lowest systolic blood pressure recorded in Group-1B was 83.27+-12.69 mmHg and in Group-HB 114.33+-13.83 mm Hg, the difference being significant (p<0.05). There was a higher incidence of complications in Group-1B as compared to Group-HB like high spinal analgesia, vomiting and discomfort. Intrathecal block showed a greater reduction in the systolic blood pressure, and associated complications, with Isobaric Bupivacaine as compared to Hyperbaric Bupivacaine. (author)

    Full Text Available Abstract Introduction: Cost management has been identified as an essential tool for the general control and evaluation of health organizations. Objectives: To identify the coverage percentage of transferred funds from the Unified Health System for coronary artery bypass grafts in a philanthropic hospital having a consolidated costing system in the municipality of São Paulo. Methods: A quantitative, descriptive and cross-sectional research with information provided from a database composed of 1913 patients undergoing coronary artery bypass graft from March 13 to September 30, 2012, including isolated elective coronary artery bypass graft with the use of extracorporeal circulation. It excluded 551 (28.8% patients, among them 76 (4.0% deaths and 8 hospitalized patients, since the cost was compared according to the length of hospital stay. Therefore, the sample consisted of 1362 patients. Results: The average total cost per patient was $7,992.55. The average fund transfer by the Unified Health System was $3,450.73 (48.66%, resulting in a deficit of $4,541.82 (51.34%. Conclusion: The Unified Health System transfers covered 48.66% of the average total cost of hospitalization. Although the amount transferred increased with increasing costs, it was not proportional to the total cost, resulting in a percentage difference in revenue that was increasingly negative for each increase in cost and hospital stay. Those hospitalized for longer than seven days presented higher costs, older age, higher percentage of diabetics and chronic kidney disease patients and more postoperative complications.

    Opium is an overwhelming public health problem in some countries. Different studies have suggested this drug as a risk factor for cardiovascular disease. Although the effect of opium on immune system, lung disease, nephropathy, stroke, and cardiac arrhythmia has been found in different studies, its effect on postoperation complications is not clear yet. The authors conducted this study to assess the effect of opium on post operation in hospital complications among patients who underwent coronary artery bypass graft. The authors retrospectively analyzed the data in this study. This study has been done at Tehran Heart Center. A total of 4,398 patients who had undergone isolated CABG were studied. Patients who fulfilled the DSM-IV-TR criteria for opium dependence (by smoking) were enrolled as Opium Dependent Patients. Also outcome variables were: Perioperative MI, septicemia, UTI, TIA, continuous coma, prolonged ventilation, pulmonary embolism, renal failure, acute limb ischemia, heart block, AF, mortality. The prevalence of opium dependence was 15.6percent among patients. The authors used a propensity matched model to analyze the relationship between opium and post operation complications. The authors adjusted opium and non-opium dependent patients in all of the baseline preoperative risk factors, so all of the matched patients were same and there was no bias in assessment. Opium dependent patients had significantly longer resource utilization. However, no significant relationship was found between opium dependence and other cardiac and non cardiac in hospital complications.

    Increased levels of visfatin, a novel adipocytokine, are reported in atherosclerosis, obesity, and type 2 diabetes. The aim of the present study was to investigate the relationship between coronary slow flow (CSF) and visfatin in patients undergoing elective coronary angiography for suspected coronary artery disease. A total of 140 recruited participants (90 patients with CSF and 50 controls) were divided into two groups according to their coronary flow rates. Coronary flow was quantified by thrombolysis in myocardial infarction (TIMI) frame count (TFC). Serum visfatin levels were higher in the CSF group than in the control group (3.29 ± 1.11 vs. 2.70 ± 1.08 ng/ml, p = 0.003). A significant correlation was found between TFC and visfatin (r = 0.535, p < 0.001). The area under the receiver operating characteristic curve was 0.720 (95 % confidence interval, 0.622-0.817, p < 0.001) for visfatin in the diagnosis of CSF. If a cut-off value of 2.59 ng/ml was used, higher levels of visfatin could predict the presence of CSF with 78.9 % sensitivity and 64.0 % specificity. Visfatin levels might be a useful biomarker for predicting CSF in patients undergoing diagnostic coronary angiography.

    Results: The incidence of cesarean section was 254 (22.30% out of which emergency cesarean section accounted for 167 (65.7% and elective cesarean section for 87 (34.3%. The usual indications of emergency cesarean section were fetal distress, previous cesarean section in labour, non progress of labour and prolonged second stage of labour. The usual indications of elective cesarean section were previous cesarean section, breech, cephalopelvic disproportion and cesarean section on demand. There was found to be no significant difference in age, period of gestation, blood loss and blood transfusion in emergency vs. elective cesarean section. There was significant difference seen in the length of hospital stay, fever, urinary tract infection, wound infection and low APGAR in five minutes indicating that these were more common in emergency cesarean section. Significant difference was also seen in the incidence of postpartum haemorrhage indicating that it was seen more in elective cesarean section. Conclusions: The incidence of cesarean section in Nepal Medical College Teaching Hospital is high and the overall complication rate is higher in emergency cesarean section than in elective cesarean section. Keywords: cesarean section; fetal and maternal outcome.

    Few data are so far available on the relation between increased glucose values and insulin resistance and mortality at short-term in patients with acute heart failure (AHF). The present investigation, performed in 409 consecutive patients with AHF complicating acute coronary syndrome (ACS), was aimed at assessing the prognostic role of admission glycaemia and acute insulin resistance (as indicated by the Homeostatic Model Assessment - HOMA index) for death during Intensive Cardiac Care (ICCU) stay. Admission glucose tertiles were considered. In our series, diabetic patients accounted for the 33%. Patients in the third glucose tertiles exhibited the lowest LVEF (both on admission and at discharge), a higher use of mechanical ventilation, intra-aortic balloon pump and inotropic drugs and the highest in-ICCU mortality rate. In the overall population, hyperglycaemic patients (both diabetic and non diabetic) were 227 (227/409, 55.5%). Admission glycaemia was an independent predictor of in-ICCU mortality, together with admission LVEF and eGFR, while acute insulin resistance (as indicated by HOMA-index) was not associated with early death. The presence of admission hyperglycaemia in non-diabetic patients was independently associated with in-ICCU death while hyperglycaemia in diabetic patients was not. According to our results, hyperglycaemia is a common finding in patients with ACS complicated by AHF and it is an independent predictor of early death. Non-diabetic patients with hyperglycaemia are the subgroup with the highest risk of early death.

    High complication rates have been cited following olfactory groove meningioma (OGM) resection but data are lacking on attendant risk factors. We aimed to review the complications following OGM resection and identify prognostic factors. A retrospective review was performed on 34 consecutive patients who underwent primary OGM resection at a single London institution between March 2008 and February 2013. Collected data included patient comorbidities, pre-operative corticosteroid use, tumour characteristics, imaging features, operative details, extent of resection, histology, use of elective post-operative ventilation, complications, recurrence and mortality. Complication rate was 39%. 58% of complications required intensive care or re-operation. Higher complication rates occurred with OGM > 40 mm diameter versus ≤ 40 mm (53 vs. 28%; p = 0.16); OGM with versus without severe perilesional oedema (59 vs. 19%; p = 0.26), more evident when corrected for tumour size; and patients receiving 1-2 days versus 3-5 days of pre-operative dexamethasone (75 vs. 19%; p = 0.016). Patients who were electively ventilated post-operatively versus those who were not had higher risk tumours but a lower complication rate (17 vs. 44%; p = 0.36) and a higher proportion making a good recovery (83 vs. 55%; p = 0.20). Complete versus incomplete resection had a higher complication rate (50 vs. 23%; p = 0.16) but no recurrence (0 vs. 25%; p = 0.07). Risk of morbidity with OGM resection is high. Higher complication risk is associated with larger tumours and greater perilesional oedema. Pre-operative dexamethasone for 3-5 days versus shorter periods may reduce the risk of complications. We describe a characteristic pattern of perilesional oedema termed 'sabre-tooth' sign, whose presence is associated with a higher complication rate and may represent an important radiological prognostic sign. Elective post-operative ventilation for patients with high-risk tumours may reduce the risk of complications.

    To assess the cost effectiveness of drug eluting stents (DES) compared with conventional stents for treatment of symptomatic coronary artery disease in the UK. Cost-utility analysis of audit based patient subgroups by means of a simple economic model. Tertiary care. 12 month audit data for 2884 patients receiving percutaneous coronary intervention with stenting at the Cardiothoracic Centre Liverpool between January 2000 and December 2002. Risk of repeat revascularisation within 12 months of index procedure and reduction in risk from use of DES. Economic modelling was used to estimate the cost-utility ratio and threshold price premium. Four factors were identified for patients undergoing elective surgery (n = 1951) and two for non-elective surgery (n = 933) to predict risk of repeat revascularisation within 12 months. Most patients fell within the subgroup with lowest risk (57% of the elective surgery group with 5.6% risk and 91% of the non-elective surgery group with 9.9% risk). Modelled cost-utility ratios were acceptable for only one group of high risk patients undergoing non-elective surgery (only one patient in audit data). Restricting the number of DES for each patient improved results marginally: 4% of stents could then be drug eluting on economic grounds. The threshold price premium justifying 90% substitution of conventional stents was estimated to be 112 pound sterling (212 USD, 162 pound sterling) (sirolimus stents) or 89 pound sterling (167 USD, 130 pound sterling) (paclitaxel stents). At current UK prices, DES are not cost effective compared with conventional stents except for a small minority of patients. Although the technology is clearly effective, general substitution is not justified unless the price premium falls substantially.

    Full Text Available The purpose of this study is to show how a tertiary care center in Turkey operating mainly in cardiology initiated Six Sigma principles to reduce the number of complications occuring during coronary stent insertion process. A Six Sigma’s Define-Measure-Analyze-Improve-Control (DMAIC model for coronary stent insertion is suggested. Data were collected for 24-months. Twenty-two Critical-to-Quality (CTQ factors were identified for successful coronary stent insertion. The most frequent causes of complications in the process were found to be patients with previous bypass surgery or PCI, inexperience of staff members, highly damaged vessel structure, thin and/or long vessel diameter, inappropriate selection of stent type, inappropriate selection of balloon type and poor image quality.

    Silent embolic cerebral infarction (SECI) is a major complication of coronary angiography (CAG) and percutaneous coronary intervention (PCI). Patients with stable coronary artery disease (CAD) who underwent CAG with or without PCI were recruited. Cerebral diffusion-weighted magnetic resonance imaging was performed for SECI within 24 hours. Clinical and angiographic characteristics were compared between patients with and without SECI. Silent embolic cerebral infarction occurred in 12 (12%) of the 101 patients. Age, total cholesterol, SYNTAX score (SS), and coronary artery bypass history were greater in the SECI(+) group (65 ± 10 vs 58 ± 11 years,P= .037; 223 ± 85 vs 173 ± 80 mg/dL,P= .048; 30.1 ± 2 vs 15 ± 3,PSECI was more common in the PCI group (8/24 vs 4/77,P= .01). On subanalysis, the SS was significantly higher in the SECI(+) patients in both the CAG and the PCI groups (29.3 ± 1.9 vs 15 ± 3,PSECI after CAG and PCI increases with the complexity of CAD (represented by the SS). The SS is a predictor of the risk of SECI, a complication that should be considered more often after CAG. © The Author(s) 2015.

    Aim: An innovative xenon–chlorine (excimer) pulsed laser catheter (ELCA X80) has been recently used for the treatment of complex coronary lesions, as calcified stenosis, chronic total occlusions and non-compliant plaques. Such complex lesions are difficult to adequately treat with balloon angioplasty and/or intracoronary stenting. The aim of this study was to examine the acute outcome of this approach on a cohort of patients with coronary lesions. Methods and Results: Eighty patients with 100 lesions were enrolled through four centers, and excimer laser coronary angioplasty was performed on 96 lesions (96%). Safety and effectiveness data were compared between patients treated with standard laser therapy and those treated with increased laser therapy. Laser success was obtained in 90 lesions (93.7%), procedural success was reached in 88 lesions (91.7%), and clinical success in was obtained in 87 lesions (90.6%). There was no perforation, major side branch occlusion, spasm, no-reflow phenomenon, dissection nor acute vessel closure. Increased laser parameters were used successfully for 49 resistant lesions without complications. Conclusions: This study suggests that laser-facilitated coronary angioplasty is a simple, safe and effective device for the management of complex coronary lesions. Furthermore, higher laser energy levels delivered by this catheter improved the device performance without increasing complications. - Highlights: • We planned this multicenter study to examine the acute outcome of an innovative xenon–chlorine (excimer) pulsed laser catheter (ELCA X80) for treatment of complex coronary lesions. • We enrolled 80 patients with 100 lesions and performed excimer laser coronary angioplasty in 96 lesions (96%). • Laser success was obtained in 90 lesions (93.7%), procedural success was reached in 88 lesions (91.7%), and clinical success was obtained in 87 lesions (90.6%). • Increased laser parameters were used successfully for 49 resistant

    Full Text Available Background: Despite recent improvement in coronary intervention, there are many controversies about it’s results in diabetic patients. The goal of this study is comparison of in hospital outcome of diabetics after coronary intervention with nondiabetics. Methods: In this study 115 diabetic and 115non diabetic patients who admitted for coronary intervention in our center during 1383&84 were entered in an analytic study of Cohort type. Datas about clinical, aniographic, procedural and post procedural (24hours characteristics were entered in each patient’s form. Independent T test,chi-square and Fisher’s exact test were used for analyzing datas. Results: The Diabetic Patients were most often older men, and they had higher angina class, more co-risk factors and lower ejection fractions. Diabetic’s lesions were longer and more located in proximal portion of vessels. But success rate, major complication (death, revascularization, Q Wave MI and CVA, and minor complications (coronary/peripheral arteries complication, pulmonary edema, ischemic ECG had no significant differences between two groups. Conclusion: Diabetes mellitus does not affect short outcomes of coronary intervention as an independent factor. So intervention could be done in these patients with considering favorable outcomes.

    To evaluate the potential benefit of systematic preoperative coronary-artery angiography followed by selective coronary-artery revascularization on the incidence of myocardial infarction (MI) in patients undergoing carotid endarterectomy (CEA) without a previous history of coronary artery disease (CAD). We randomised 426 patients who were candidates for CEA, with no history of CAD, a normal electrocardiogram (ECG), and a normal cardiac ultrasound. In group A (n = 216) all patients underwent coronary angiography before CEA. In group B (n = 210) CEA was performed without coronary angiography. Patients were not blinded for relevant assessments during follow-up. Primary end-point was the occurrence of MI at 3.5 years. The secondary end-point was the overall survival rate. Median length of follow-up was 6.2 years. In group A, coronary angiography revealed significant coronary artery stenosis in 68 patients (31.5%). Among them, 66 underwent percutaneous Intervention (PCI) prior to CEA and 2 received combined CEA and coronary-artery bypass grafting (CABG). Postoperatively, no MI was observed in group A, whereas 6 MI occurred in group B, one of which was fatal (p = .01). During the study period, 3 MI occurred in group A (1.4%) and 33 were observed in group B (15.7%), 6 of which were fatal. The Cox model demonstrated a reduced risk of MI for patients in group A receiving coronary angiography (HR,.078; 95% CI, 0.024-0.256; p < .001). In addition, patients with diabetes and patients <70 years presented with an increased risk of MI. Survival analysis at 6 years by Kaplan-Meier estimates was 95.6 ± 3.2% in Group A and 89.7 ± 3.7% in group B (Log Rank = 6.54, p = .01). In asymptomatic coronary-artery patients, systematic coronary angiography prior to CEA followed by selective PCI or CABG significantly reduces the incidence of late MI and increases long-term survival.

    Full Text Available Objective: To study the effect of telmisartan combined with lipid-lowering drug therapy on serum lipid metabolism index and cytokine levels in patients with type 2 diabetes mellitus complicated by coronary heart disease. Methods: A total of 106 patients with type 2 diabetes mellitus complicated by coronary heart disease who were treated in our hospital between September 2013 and October 2016 were collected and then divided into the control group (n=55 who received conventional treatment + lipid-lowering drug treatment and the observation group (n=51 who received conventional treatment + lipid-lowering drug + telmisartan treatment after the therapies were reviewed. Before and after treatment, serum levels of lipid metabolism indexes, inflammatory mediators and oxidative stress indexes were compared between two groups of patients. Results: Before treatment, the differences in serum levels of lipid metabolism indexes, inflammatory mediators and oxidative stress indexes were not statistically significant between two groups of patients. After treatment, serum TG and LDL-C levels in observation group were lower than those in control group while HDL-C level was higher than that in control group; serum inflammatory mediators IL-6, IL-8, HMGB1 and TNF-α levels were lower than those in control group; serum oxidative stress indexes MDA and ROS levels were lower than those in control group while GSH-Px level was higher than that in control group. Conclusion: Telmisartan combined with lipid-lowering drug therapy can effectively optimize the lipid metabolism and reduce the systemic inflammatory response and oxidative stress response in patients with type 2 diabetes mellitus complicated by coronary heart disease.

    During percutaneous transluminal coronary angioplasty, the appearance of persistent staining in the vessel by contrast media suggests coronary dissection. We report seven patients in whom a false image of severe coronary dissection was observed during angioplasty performed with the new Monorail balloon catheter. This image emerges at the moment of balloon inflation, is distally located to the balloon, and disappears with balloon catheter deflation. No complications were associated with the appearance of this image.

    Iatrogenic coronary dissection is a rare but potentially serious complication of coronary angiography and angioplasty. Treatment with angioplasty guided only by angiography is often difficult. Optical coherence tomography imaging seems to be an interesting technique to lead the management of iatrogenic coronary dissection. Diagnosis can be made by optical coherence tomography; it can also eliminate differential diagnosis. Furthermore, this technique can guide safely the endovascular treatment. - Highlights: • Iatrogenic coronary dissection remains a challenging problem in angiography. • Endocoronary imaging is helpful for the diagnosis of iatrogenic coronary dissection. • OCT is a safe option to manage the endovascular treatment of coronary dissection.

    OBJECTIVES: This study sought to evaluate and compare in vivo acute stent recoil of a novel bioabsorbable stent and a metallic stent. BACKGROUND: The bioabsorbable everolimus-eluting coronary stent (BVS) is composed of a poly-L-lactic acid backbone, coated with a bioabsorbable polymer containing...... the antiproliferative drug, everolimus, and expected to be totally metabolized and absorbed in the human body. Because the BVS is made from polymer, it may have more acute recoil than metallic stents in vivo. METHODS: A total of 54 patients, who underwent elective stent implantation for single de novo native coronary...... artery lesions, were enrolled: 27 patients treated with the BVS and 27 patients treated with the everolimus-eluting cobalt chromium stent (EES). Acute absolute recoil, assessed by quantitative coronary angiography, was defined as the difference between mean diameter of the last inflated balloon...

    The Monorail system (Schneider) consists of a balloon catheter in which the guidewire passes through the balloon itself, exits the catheter proximal to the balloon, and runs alongside its small shaft (3 French) through the length of the guiding catheter. It offers distinct advantages over conventional systems of coronary angioplasty. It facilitates contrast injections and permits rapid balloon exchanges. This system was used for coronary angioplasty in 273 unselected consecutive patients (age 59 +/- 10, mean 35 to 73 years). There were 216 patients (84%) undergoing single-vessel and 57 patients (16%) with multi-vessel coronary angioplasty. A total of 335 coronary stenoses were dilated, which included 35 total occlusions. The size of balloon used ranged from 2.0 to 4.25 mm (3.0 +/- 0.5 mm) and the severity of stenosis was 85 +/- 11%. Technical success was defined as a residual stenosis of less than 50% as determined angiographically. Clinical success was defined as technical success, and absence of a major inhospital complication defined as absence of myocardial infarction, lack of need for coronary arterial bypass surgery, and survival. The Monorail system was technically successful in 294/300 stenotic lesions (98%). It was clinically successful for 281 lesions (94%). Of the 35 total occlusions, technical success was obtained in 25 (71%). The residual stenosis of successful cases was 26 +/- 21%. The Monorail system was also successful in 5 patients with stenosis of more than 90% in whom conventional systems failed. The complications included acute occlusion causing acute myocardial infarction in 13 cases (5%), emergency coronary arterial bypass surgery in 1 patient (0.4%), and death in 4 patients (1.5%).(ABSTRACT TRUNCATED AT 250 WORDS)

    We explored the prevalence and pattern of abnormal myocardial perfusion in patients with isolated coronary artery ectasia (CAE), as demonstrated by (99m)Tc-sestamibi scintigraphy. Prospectively, we enrolled 35 patients with angiographically documented CAE and no significant coronary obstruction, who underwent elective coronary angiography. Patients underwent Stress-rest (99m)Tc-sestamibi scintigraphy within 4 days of coronary angiography. They were divided into 2 groups: group I: with normal perfusion scan; and group II: with reversible perfusion defects. The mean age was 49.6 ± 6.9 years; 34 (97.1 %) were males. Seventy-nine (75.2 %) arteries were affected by CAE. Among 79 arteries affected by CAE, affection was diffuse in 37 (46.8 %). Thirteen (37.1 %) patients had normal perfusion scan (group I), whereas 22 (62.9 %) had reversible perfusion defects (group II). Among 22 patients with reversible perfusion defects, 20 (90.9 %) had mild and 2 (9.1 %) had moderate ischemia. Among 49 myocardial segments with reversible perfusion defects, 22 (44.9 %) were basal, 18 (36.7 %) mid-, and 9 (18.4 %) apical segments. Diffuse CAE was significantly more prevalent in group II versus group I, in all 3 major coronary arteries (p < 0.05 for all). In patients with isolated CAE who underwent elective coronary angiography, reversible perfusion defects demonstrated by (99m)Tc-sestamibi scintigraphy were rather prevalent, mostly mild, more likely to affect the basal and mid-segments of the myocardium, and more frequently associated with diffuse ectasia.

    Full Text Available Postmyocardial infarction ventricular septal defect is an increasingly rare mechanical complication of acute myocardial infarction. We present a case of acute myocardial infarction from right coronary artery occlusion that developed hypotension and systolic murmur 12 hours after successful percutaneous coronary intervention. Although preoperative imaging suggested a large ventricular septal defect and a pseudoaneurysm, intraoperative findings concluded a serpiginous dissection of the ventricular septum. The imaging technicalities are discussed.

    Objective: To compare the relative safety and efficacy of Cypher and Taxus stent in coronary heart disease complicated with diabetes. Methods: A retrospective study of our hospital's Cardiology database containing one hundred and twenty-two CHD complicated with diabetes undergone selective or urgent implantation of DES stent between June 2002 and February 2004 were divided into Cypher stent group (n=31) and Taxus stent group (n=91). The endpoints included cardiac death ,myocardial infarction (MI) and TLR at 6-month. Results: 122 patients with majority of males (80%) and mean age of 56 ± 11 years. The baseline characteristics were similar in both groups. Majority lesions treated were consisted of AHA/ACC Type B2/C (75%). Compared to the Taxus group, the Cypher group had a smaller mean reference diameter (2.4±0.6 mm versus 2.6±0.7 mm, P TM and (Taxus) TM coronary stents are proved to be equally safe and effective with low rate of clinical restenosis, TLR and MACE at 6-month in coronary heart disease complicated with diabetes patients.

    Data comparing the clinical benefits of medical treatment with those of percutaneous coronary intervention (PCI) in an elderly population with angina pectoris are limited. Therefore, we evaluated the efficacy of elective PCI versus optimal medical treatment (OMT) in elderly patients (between 75 and 84 years old) with angina pectoris. One hundred seventy-seven patients with significant coronary artery stenosis were randomly assigned to either the PCI group (n=90) or the OMT group (n=87). The primary outcome was a composite of major adverse events in the 1-year follow-up period that included cardiovascular death, non-fatal myocardial infarction, coronary revascularization, and stroke. Major adverse events occurred in 5 patients (5.6%) of the PCI group and in 17 patents (19.5%) of the OMT group (p=0.015). There were no significant differences between the PCI group and the OMT group in cardiac death [hazard ratio (HR) for the PCI group 0.454; 95% confidence interval (CI) 0.041-5.019, p=0.520], myocardial infarction (HR 0.399; 95% CI 0.039-4.050, p=0.437), or stroke (HR 0.919; 95% CI 0.057-14.709, p=0.952). However, the PCI group showed a significant preventive effect of the composite of major adverse events (HR 0.288; 95% CI 0.106-0.785, p=0.015) and against the need for coronary revascularization (HR 0.157; 95% CI 0.035-0.703, p=0.016). Elective PCI reduced major adverse events and was found to be an effective treatment modality in elderly patients with angina pectoris and significant coronary artery stenosis, compared to OMT.

    The aim of this study is to assess the value of early elective cesarean delivery for patients with gastroschisis in comparison with late spontaneous delivery. Analysis of infants with gastroschisis admitted between 1986 and 2006 at a tertiary care center was performed. The findings were analyzed statistically. Eighty-six patients were involved in the study. This included 15 patients who underwent emergency cesarean delivery (EM CD group) because of fetal distress and/or bowel ischemia. The remaining 71 patients born electively were stratified into 4 groups. The early elective cesarean delivery (ECD) group included 23 patients born by ECD before 36 weeks; late vaginal delivery (LVD) group included 23 patients who had LVD after 36 weeks; 24 patients had LCD after 36 weeks because of delayed diagnosis that resulted in late referral; and 1 patient had early spontaneous vaginal delivery (EVD group) before 36 weeks. The mean time to start oral feeding, incidence of complications, and primary closure were significantly better in the ECD group than in the LVD group. The duration of ventilation and the length of stay were shorter in ECD group, but the difference was not statistically significant. Elective cesarean delivery before 36 weeks allows earlier enteral feeding and is associated with less complications and higher incidence of primary closure (statistically significant).

    Background: In the past 30 years the rate of caesarean section (C/S) has steadily increased from 5% to more than 20% for many avoidable and unavoidable indications. The objective of this study was to compare maternal morbidity and determine its cause in elective and emergency caesarean section. Method: It was a cross-sectional comparative study conducted in Civil Hospital Karachi at Obs/Gyn Unit III. All mothers admitted through OPD or emergency during the study period, of any age or parity undergoing C/S were recruited in the study. Patients having previous myomectomy, hysterotomy or classical C/S were excluded from the study. Patients undergoing emergency C/S were placed in group A, and those delivered by elective C/S were included in group B. Study variables were general and obstetric parameters and complications observed intra-operatively. Any postoperative complications were recorded from recovery room till patient was discharged from the ward. Results: There were 50 patients in each group. In group A, 11 (22%) were booked and 33 (66%) were referred cases. In group B, 48 (96%) were booked. The mean age in both groups was 28 years. In both groups, multigravida compared to primigravida were 78% vs 22% in group A, and 92% vs 8% in group B. Indication for C/S was previous C/S in 10 (20%) patients in group A, and 39 (78%) patients in group B, placenta previa, chorioamionitis, obstructed labour (6, 12% each); pregnancy induced hypertension and eclampsia in 5 (10%) cases in group A only. Intra-operative complications in group A were 48 (96%) vs 15 (30%) in group B (p=0.000). Postoperative morbidity in group A was 50 (100%) and 26 (52%) in group B (p=0.000). Intra-operative complication was haemorrhage in 46 (92%) cases in group A and 11 (22%) in group B. Anaesthetic complications were 40 (80%); prolonged intubation 25 (50%), aspiration of gastric contents 8 (16%), and difficult intubation 7 (14%) in group A. Ten (20%) cases had anaesthetic complications in group B

    To determine whether the perioperative use of hydroxyethyl starch 6% and albumin 5% in elective joint arthroplasties are associated with an increased risk for perioperative complications. Retrospective cohort study of population based data between 2006 and 2013. Data from 510 different hospitals across the United States participating in the Premier Perspective database. 1,051,441 patients undergoing elective total hip and knee arthroplasties. Perioperative fluid resuscitation with hydroxyethyl starch 6% or albumin 5%, or neither. Acute renal failure and thromboembolic, cardiac, and pulmonary complications. Compared with patients who received neither colloid, perioperative fluid resuscitation with hydroxyethyl starch 6% or albumin 5% was associated with an increased risk of acute renal failure (odds ratios 1.23 (95% confidence interval 1.13 to 1.34) and 1.56 (1.36 to 1.78), respectively) and most other complications. A recent decrease in hydroxyethyl starch 6% use was noted, whereas that of albumin 5% increased. Similar to studies in critically ill patients, we showed that use of hydroxyethyl starch 6% was associated with an increased risk of acute renal failure and other complications in the elective perioperative orthopedic setting. This increased risk also applied to albumin 5%. These findings raise questions regarding the widespread use of these colloids in elective joint arthroplasty procedures. © Opperer et al 2015.

    Full Text Available Background: Different approaches are available to irrigate the arterial catheter, such as continuous and intermittent techniques. However, there is a disagreement regarding the most appropriate method. Aim: this study aimed to compare the effect of two continuous and intermittent irrigation methods on complications of arterial catheter and partial thromboplastin time (PTT in patients with coronary artery bypass (CABG surgery. Method: This randomized clinical trial was conducted on 60 participants undergoing coronary artery bypass grafting surgery in open-heart surgery ICU at Imam Reza hospital in Mashhad, Iran, in 2016. In continuous group, the arterial catheter was continuously irrigated with heparin solution at the rate of 2cc/h, and in the intermittent group with a syringe containing 5cc heparin solution every 3 hours. In both groups, catheter was monitored and recorded every 3 hours (until 48 hours and 3 times from enrollment in terms of complications of partial thromboplastin time. Data were analyzed using SPSS version 16. Results: The findingsof independent t-test showed that the two groups are homogeneous in age (P =0.48. The result of Fisher's exact test revealed no significant difference between the two groups in terms of average incidence of complications during the first 24 hours (P=0.55 and second 24 hours (P=0.55 after catheterization. Also during the 48 hours after surgery, independent t-test results showed no statistically significant difference in partial thromboplastin time (P=0.53 between the two groups. Implications for Practice: According to the results of the research based on the lack of difference between continuous and intermittent irrigation methods up to 48 hours after catheter replacement in terms of arterial catheter complications, further long-term follow-up researches are recommended.

  9. Coronary plaque morphology on multi-modality imagining and periprocedural myocardial infarction after percutaneous coronary intervention

    2016-06-01

    Full Text Available Percutaneous coronary intervention (PCI may be complicated by periprocedural myocardial infarction (PMI as manifested by elevated cardiac biomarkers such as creatine kinase (CK-MB or troponin T. The occurrence of PMI has been shown to be associated with worse short- and long-term clinical outcome. However, recent studies suggest that PMI defined by biomarker levels alone is a marker of atherosclerosis burden and procedural complexity but in most cases does not have independent prognostic significance. Diagnostic multi-modality imaging such as intravascular ultrasound, optical coherence tomography, coronary angioscopy, near-infrared spectroscopy, multidetector computed tomography, and magnetic resonance imaging can be used to closely investigate the atherosclerotic lesion in order to detect morphological markers of unstable and vulnerable plaques in the patients undergoing PCI. With the improvement of technical aspects of multimodality coronary imaging, clinical practice and research are increasingly shifting toward defining the clinical implication of plaque morphology and patients outcomes. There were numerous published data regarding the relationship between pre-PCI lesion subsets on multi-modality imaging and post-PCI biomarker levels. In this review, we discuss the relationship between coronary plaque morphology estimated by invasive or noninvasive coronary imaging and the occurrence of PMI. Furthermore, this review underlies that the value of the multimodality coronary imaging approach will become the gold standard for invasive or noninvasive prediction of PMI in clinical practice.

    Contemporary real-world data on clinical outcomes after utilization of coronary atherectomy are sparse. The study cohort was derived from Healthcare Cost and Utilization Project Nationwide Inpatient Sample database from year 2012. Percutaneous coronary interventions including atherectomy were identified using appropriate International Classification of Diseases, 9th Revision diagnostic and procedural codes. Two-level hierarchical multivariate mixed models were created. The primary outcome was a composite of in-hospital mortality and periprocedural complications; the secondary outcome was in-hospital mortality. Hospitalization costs were also assessed. A total of 107,131 procedures were identified in 2012. Multivariate analysis revealed that atherectomy utilization was independently predictive of greater primary composite outcome of in-hospital mortality and complications (odds ratio 1.34, 95% confidence interval 1.22 to 1.47, p atherectomy utilization was again associated with a higher rate of complications (12.88% vs 10.99%, p = 0.001), in-hospital mortality +a ny complication (13.69% vs 11.91%, p = 0.003) with a nonsignificant difference in terms of in-hospital mortality alone (3.45% vs 2.88%, p = 0.063) and higher hospitalization costs ($25,341 ± 353 vs $21,984 ± 87, p Atherectomy utilization during percutaneous coronary intervention is associated with a higher rate of postprocedural complications without any significant impact on in-hospital mortality.

    To evaluate the usefulness of systematic coronary angiography followed, if needed, by coronary artery angioplasty (percutaneous coronary intervention (PCI)) on the incidence of cardiac ischaemic events after carotid endarterectomy (CEA) in patients without evidence of coronary artery disease (CAD). From January 2005 to December 2008, 426 patients, candidates for CEA, with no history of CAD and with normal cardiac ultrasound and electrocardiography (ECG), were randomised into two groups. In group A (n=216) all the patients had coronary angiography performed before CEA. In group B, all the patients had CEA without previous coronary angiography. In group A, 66 patients presenting significant coronary artery lesions at angiography received PCI before CEA. They subsequently underwent surgery under aspirin (100 mg day(-1)) and clopidogrel (75 mg day(-1)). CEA was performed within a median delay of 4 days after PCI (range: 1-8 days). Risk factors, indications for CEA and surgical techniques were comparable in both groups (p>0.05). The primary combined endpoint of the study was the incidence of postoperative myocardial ischaemic events combined with the incidence of complications of coronary angiography. Secondary endpoints were death and stroke rates after CEA and incidence of cervical haematoma. Postoperative mortality was 0% in group A and 0.9% in group B (p=0.24). One postoperative stroke (0.5%) occurred in group A, and two (0.9%) in group B (p=0.62). No postoperative myocardial event was observed in group A, whereas nine ischaemic events were observed in group B, including one fatal myocardial infarction (p=0.01). Binary logistic regression analysis demonstrated that preoperative coronary angiography was the only independent variable that predicted the occurrence of postoperative coronary ischaemia after CEA. The odds ratio for coronary angiography (group A) indicated that when holding all other variables constant, a patient having preoperative coronary angiography

    To examine differences between Queensland and Victorian coding of hospital-acquired conditions and suggest ways to improve the usefulness of these data in the monitoring of patient safety events. Secondary analysis of admitted patient episode data collected in Queensland and Victoria. Comparison of depth of coding, and patterns in the coding of ten commonly coded complications of five elective procedures. Comparison of the mean complication codes assigned per episode revealed Victoria assigns more valid codes than Queensland for all procedures, with the difference between the states being significantly different in all cases. The proportion of the codes flagged as complications was consistently lower for Queensland when comparing 10 common complications for each of the five selected elective procedures. The estimated complication rates for the five procedures showed Victoria to have an apparently higher complication rate than Queensland for 35 of the 50 complications examined. Our findings demonstrate that the coding of complications is more comprehensive in Victoria than in Queensland. It is known that inconsistencies exist between states in routine hospital data quality. Comparative use of patient safety indicators should be viewed with caution until standards are improved across Australia. More exploration of data quality issues is needed to identify areas for improvement.

    To assess the relationship of parameters of obesity in relationship to coronary angiography findings with correlation of epicardial fat (EF) thickness in uppermentioned context. There were 80 patients examined (43 males, 37 postmenopausal females) undergoing elective coronary angiography. We examined the regular obesity parameters - BMI, waist circumference (WC), neck circumference (NC), total body fat (TBF), and visceral fat (VF) using bioimpedance. We assessed the echocardiographically measured EF thickness. We added examination of lipidogram, glycaemia, HOMA-IR (insulin resistance index) and AIP (aterogenic index of plasma). The set was divided into group with coronarographically proved stenosis or stenoses (withCS), and a group without finding of quantifiable stenosis or stenoses (withoutCS). The average thickness of EF in withCS group was 6.3 vs 5.6 mm in group withoutCS (p obesity parameters in assessment of pre-clinical stages of coronary atherosclerosis and prediction of risk of coronary heart disease. In adipose parameters, EF thickness was correlated the most by WC. Risk stratification of coronary artery disease is supplemented by increased HOMA-IR and AIP.

    Lengthy waiting lists for coronary angiography have been described in many health care systems worldwide. The extent to which formal queue management systems may improve the prioritization and survival of patients in the angiography queue is unknown. To prospectively evaluate the performance of a formal queue management system for patients awaiting coronary angiography in Ontario. The coronary angiography urgency scale, a formal queue management system developed in 1993 using a modified Delphi panel, allocates recommended maximum waiting times (RMWTs) in accordance with clinical necessity. By using a provincial clinical registry, 35,617 consecutive patients referred into the coronary angiography queue between April 1, 2001, and March 31, 2002, were prospectively tracked. Cox proportional hazards models were used to examined mortality risk across urgency after adjusting for additional clinical and comorbid factors. Good agreement was determined in urgency ratings between scores from the coronary angiography urgency scale and implicit physician judgement, which was obtained independently at the time of the index referral (weighted kappa = 0.49). The overall mortality in the queue was 0.3% (0.47%, 0.26% and 0.13% for urgent, semiurgent and elective patients, respectively). Urgency, as specified by the coronary angiography urgency scale, was the strongest predictor of death in the queue (Pqueue management system may decrease mortality in the coronary angiography queue. The authors recommend its implementation in health care systems where patients experience excessive waiting time delays for coronary angiography.

    Infective endocarditis complicated by abscess formation and coronary artery compression is a rare clinical event with a high mortality rate, and diagnosis requires a heightened degree of suspicion. We present the clinical, angiographic, and echocardiographic features of a 73-year-old woman who presented with dyspnea and was found to have right coronary artery compression that was secondary to abscess formation resulting from diffuse infectious endocarditis. We discuss the patient's case and briefly review the relevant medical literature. To our knowledge, this is the first reported case of abscess formation involving a native aortic valve and the right coronary artery.

    Coronary artery disease (CAD) is multifactorial disease, in which thrombotic occlusion and calcification occur usually. New strategies have been made for diagnosis and treatment of CAD, such as transradial catheterization. Hemostasis could be done in two approaches: traditional and patent. Our aim is to find the best approach with lowest complication. In a comparative study, 120 patients were recruited and divided randomly into two subgroups, including traditional group (60 patients; 24 females, 36 males; mean age: 64.35 ± 10.56 years) and patent group (60 patients; 28 females, 32 males; mean age: 60.15 ± 8.92 years). All demographic data including age, gender, body mass index, and CAD-related risk factors (smoking, diabetes, hypertension) and technical data including the number of catheters, procedure duration, and hemostatic compression time and clinical outcomes (radial artery occlusion [RAO], hematoma, bleeding) were collected. Data were analyzed by SPSS version 16. Our findings revealed that the incidence of RAO was significantly lower in patent groups compared with traditional group ( P = 0.041). Furthermore, the difference incidence of RAO was higher in early occlusion compare with late one ( P = 0.041). Moreover, there were significant relationship between some factors in patients of traditional group with occlusion (gender [ P = 0.038], age [ P = 0.031], diabetes mellitus [ P = 0.043], hemostatic compression time [ P = 0.036]) as well as in patent group (age [ P = 0.009], hypertension [ P = 0.035]). Our findings showed that RAO, especially type early is significantly lower in patent method compared classic method; and patent hemostasis is the safest method and good alternative for classical method.

    identified. The first addressed ethical aspects regarding the principles of beneficence, autonomy and justice, and the second addressed those regarding radiation exposition, especially when used within studies.Discussion: The discriminatory power of CT coronary angiography to identify patients with obstructive (above 50 % coronary stenoses should be regarded as “high diagnostic evidence”, to identify patients without coronary stenoses as “persuasive diagnostic evidence”. The discriminatory power of both types of coronary angiography to identify patients with or without functionally relevant coronary stenoses should be regarded as “weak diagnostic evidence”. It can be assumed that patients with a high pretest probability of CHD will need invasive coronary angiography and patients with a low pretest probability of CHD will not need subsequent revascularisation. Therefore, CT coronary angiography may be used before performing invasive coronary angiography in patients with an intermediate pretest probability of CHD. For identifying or excluding of obstructive coronary stenosis, CT coronary angiography was shown to be more cost-saving at a pretest probability of CHD of 50 % or lower, and invasive coronary angiography at a pretest probability of CHD of 70 % or higher. The use of both types of coronary angiography to identify or to exclude functionally relevant coronary stenoses should be regarded as highly cost-consuming. With regard to ethical, social or legal aspects, the following possible implications were identified: under-provision or over-provision of health care, unnecessary complications, anxiety, social stigmatisation, restriction of self-determination, unequal access to health care, unfair resource distribution and legal disputes.Conclusion: From a medical point of view, CT coronary angiography using scanners with at least 64 slices should be recommended as a test to rule out obstructive coronary stenoses in order to avoid inappropriate invasive coronary

    Coronary artery calcifications are well seen on CT scans because of high contrast resolution. Individual vessels were scored 0-3+ based on degree of calcification in over 40 patients who also underwent cardiac catheterization. Though relatively insensitive, the presence of dense calcifications had a specificity of roughly 60% to 70% for the presence of severe stenosis. In addition, 30 patients with calcification on CT scans and 30 age-matched controls, all of whom underwent thoracotomy, were compared with respect to prior cardiac history, estimated anesthetic risk, and postoperative cardiac complications. Patients with calcifications were more likely to have evidence of coronary disease and/or encounter postoperative cardiac complications

    Full Text Available Modern surgery is faced with the emergence of newer “risk factors” and the challenges associated with identifying and managing these risks in the perioperative period. Obstructive sleep apnea and obesity hypoventilation syndrome pose unique challenges in the perioperative setting. Recent studies have identified some of the specific risks arising from caring for such patients in the surgical setting. While all possible postoperative complications are not yet fully established or understood, the prevention and management of these complications pose even greater challenges. Pulmonary hypertension with its changing epidemiology and novel management strategies is another new disease for the surgeon and the anesthesiologist in the noncardiac surgical setting. Traditionally most such patients were not considered surgical candidates for any required elective surgery. Our review discusses these disease entities which are often undiagnosed before elective noncardiac surgery.

    There is little published data reporting outcomes for those found to have a chronic total coronary occlusion (CTO) that is electively treated medically versus those treated by percutaneous coronary intervention (PCI). We sought to compare long-term clinical outcomes between patients treated by PCI and elective medical therapy in a consecutive cohort of patients with an identified CTO. Patients found to have a CTO on angiography between January 2002 and December 2007 in a single tertiary centre were identified using a dedicated database. Those undergoing CTO PCI and elective medical therapy to the CTO were propensity matched to adjust for baseline clinical and angiographic differences. In total, 1957 patients were identified, a CTO was treated by PCI in 405 (20.7%) and medical therapy in 667 (34.1%), 885 (45.2%) patients underwent coronary artery bypass graft surgery. Of those treated by PCI or medical therapy, propensity score matching identified 294 pairs of patients, PCI was successful in 177 patients (60.2%). All-cause mortality at 5 years was 11.6% for CTO PCI and 16.7% for medical therapy HR 0.63 (0.40 to 1.00, p=0.052). The composite of 5-year death or myocardial infarction occurred in 13.9% of the CTO PCI group and 19.6% in the medical therapy group, HR 0.64 (0.42 to 0.99, p=0.043). Among the CTO PCI group, if the CTO was revascularised by any means during the study period, 5-year mortality was 10.6% compared with 18.3% in those not revascularised in the medical therapy group, HR 0.50 (0.28-0.88, p=0.016). Revascularisation, but not necessarily PCI of a CTO, is associated with improved long-term survival relative to medical therapy alone. Published by the BMJ Publishing Group Limited.

    Objective: To compare the severity of carotid artery disease in diabetic and non-diabetic patients undergoing coronary artery bypass grafting. Methods: From January to June 2008, 379 patients undergoing elective coronary artery bypass surgery were preoperatively evaluated for the presence of carotid stenoses by duplex scanning. Patients were divided into two groups, Group I, 156 (41.2%) diabetic patients and Group II, 223 (58.8%) non-diabetic patients. Results: There were 314 (82.8%) males and 65 (17.2%) females with a mean age of 57.2+-9.1 years. In diabetic group there were 125 (80.1%) males and 31 (19.9%) females with a mean age of 56.3+-8.9 years. Left main stem stenosis was present in 59 (37.8%) diabetics and 45 (20.2%) non-diabetics (p 70% stenosis was present in 20 (5.3%) with 13 (8.3%) diabetics and 7 (3.1%) non-diabetics (p<0.025). Stenosis of 50-70% was observed in 30 (7.9%) of which 17 (10.9%) were diabetics and 13 (5.8%) were non-diabetics. Conclusion: Presence of diabetes mellitus is associated with diffuse coronary artery disease and significant carotid artery disease in patients undergoing coronary artery bypass grafting. (author)

  11. An overview of the health economic implications of elective caesarean section.

    2013-12-01

    The caesarean section rate has continued to increase in most industrialised countries, which raises a number of economic concerns. This review provides an overview of the health economic implications of elective caesarean section. It provides a succinct summary of the health consequences associated with elective caesarean section for both the infant and the mother over the perinatal period and beyond. It highlights factors that complicate our understanding of the health consequences of elective caesarean section, including inconsistencies in definitions and coding of the procedure, failure to adopt an intention-to-treat principle when drawing comparisons, and the widespread reliance on observational data. The paper then summarises the economic costs associated with elective caesarean section. Evidence is presented to suggest that planned caesarean section may be less costly than planned vaginal birth in some clinical contexts, for example where the singleton fetus lies in a breech position at term. In contrast, elective caesarean section (or caesarean section as a whole) appears to be more costly than vaginal delivery (either spontaneous or instrumented) in low-risk or unselected populations. The paper proceeds with an overview of economic evaluations associated with elective caesarean section. All are currently based on decision-analytic models. Evidence is presented to suggest that planned trial of labour (attempted vaginal birth) following a previous caesarean section appears to be a more cost-effective option than elective caesarean section, although its cost effectiveness is dependent upon the probability of successful vaginal delivery. There is conflicting evidence on the cost effectiveness of maternal request caesareans when compared with trial of labour. The paucity of evidence on the value pregnant women, clinicians and other groups in society place on the option of elective caesarean section is highlighted. Techniques that might be used to elicit

    Both malnutrition and obesity are related to worsened post-operative outcomes after colorectal surgery. Obese cancer patients may be malnourished as a result of short-term weight loss. The present study aimed to evaluate preoperative nutritional status, body composition and dietary intake related to post-operative complications (POC) and post-operative hospital days (POHD) in elective colorectal cancer (CRC) patients. Anthropometry, body composition measured by bioelectric spectroscopy and dietary habits assessed by a validated food-frequency questionnaire were examined in 100 newly-diagnosed CRC patients. Data from 30-day POC and POHD were collected from medical records. Nonparametric and chi-squared tests and logistic regression were used to analyse associations between body and dietary variables and post-operative outcome. Twenty-nine patients had at least one POC. The median POHD was six. Body size and composition measures and short-term weight loss were no different between patients with and without POC, or between patients with POHD body size, body composition and short-term weight loss were not related to 30-day post-operative outcomes in CRC patients. A high content of marine n-3 PUFA in preoperative habitual diets may protect against POC after CRC surgery. © 2012 The Authors Journal of Human Nutrition and Dietetics © 2012 The British Dietetic Association Ltd.

    SAGER, Hendrik B.; NAHRENDORF, Matthias

    2016-01-01

    Atherosclerosis is a chronic inflammatory disease of the vessel wall and a major cause of death worldwide. One of atherosclerosis’ most dreadful complications are acute coronary syndromes that comprise ST-segment elevation myocardial infarction, non-ST-segment elevation myocardial infarction, and unstable angina. We now understand that inflammation substantially contributes to the initiation, progression, and destabilization of atherosclerosis. In this review, we will focus on the role of inflammatory leukocytes, which are the cellular protagonists of vascular inflammation, in triggering disease progression and, ultimately, the destabilization that causes acute coronary syndromes.

    Aim: To assess the accuracy of clinical coronary computed tomography angiography (CTA) data compared to invasive coronary angiography, and to determine the prognostic value of a negative coronary CTA examination in symptomatic, intermediate-risk patients. Methods: Thirty-seven months of coronary CTA data were audited. Seventy-eight patients were identified who had undergone coronary CTA followed by invasive coronary angiography (ICA) to determine the accuracy of CTA versus ICA. One hundred and seventy-eight patients were identified who had a 'negative' coronary CTA to enable evaluation of the prognostic value of a negative CTA examination. Results: Of the 78 patients in the accuracy analysis group there were 43 true-negative, two false-negative, 26 true-positive, and seven false-positive results producing a sensitivity of 92.9%, specificity of 86%, negative predictive value of 95.6%, and positive predictive value of 78.8%. The 178 patients who had a negative coronary CTA examination were followed up for a mean of 366 days and were all alive (0% mortality) with no episodes of myocardial infarction or unstable angina; two patients underwent elective revascularization procedures (1.1%). Conclusion: According to medium-term analysis, the accuracy of the clinical coronary CTA programme is in line with published trial data, producing excellent sensitivity and negative predictive values. The finding of a negative coronary CTA in symptomatic, intermediate-risk patients appears to confer a good prognosis, at mean follow-up of 1 year, with no deaths or episodes of myocardial infarction or unstable angina. This suggests that the prognostic value of a negative coronary CTA may be similar to that conferred by negative myocardial perfusion scintigraphy or stress echocardiography.

  19. Technical Considerations of Giant Right Coronary Artery Aneurysm Exclusion

    Full Text Available Giant coronary artery aneurysms are rare clinical entities. We report the case of a 49-year-old man who presented with dyspnoea and exertional chest pain. Investigations confirmed an aneurysmal right coronary artery measuring 4 cm with a fistulous communication to the right atrium. Following right atriotomy, the fistula was oversewn and the aneurysmal right coronary artery ligated at its origin and at several points along its course. A saphenous vein graft was anastomosed to the posterior descending artery. Persistent ventricular fibrillation occurred upon chest closure, attributed to ischaemia following ligation of the aneurysmal coronary artery. Emergent resternotomy and internal defibrillation were successfully performed. The sternum was stented open to reduce right ventricular strain and closed the following day. The patient made an unremarkable recovery. We here address the technical challenges associated with surgical repair of right coronary aneurysms and the physiology and management of potential complications.

    We investigated zinc and copper levels in angiographically defined obstructive coronary artery disease (CAD) in patients undergoing elective coronary angiography in El-Shaab Hospital, Sudan. We performed a cross-sectional study. One hundred forty-two patients were enrolled. Sociodemographic and medical characteristics were collected using a questionnaire. Glucose, lipid, zinc, and copper levels were measured. Out of 142 patients, 102 (71.8%) had CAD and 40 (28.2%) had patent coronary arteries. There were no significant differences in median (interquartile range) zinc [118.5 (97.2-151.0) vs. 130.0 (106.0-174.0) μg/ml, P = 0.120] and copper [150.6 (125.0-183.0) vs. 158 (132.0-180.0) μg/mL, P = 0.478] levels between patients with CAD and those with patent coronary arteries. In linear regression analysis, there were no associations between CAD and zinc and copper levels. The current study failed to show any significant association between CAD and zinc and copper levels.

    Colonic diverticula in reality are herniations of the mucosa through a thickened musculature of the bowel wall where it is penetrated by the vasa recta. Their prevalence increases with western food and with age. Low-residue diet and increased intraluminal pressure are considered to be etiologic factors. Diverticular disease is characterised by inflammatory and bleeding complications. Diverticulitis may lead to peridiverticulitis and pericolitis with frank peritonitis. Uncomplicated diverticulosis warrants observation only under dietary guidance. Repeated complications indicate elective operation by one-stage-resection. Perforation, abscess and massive bleeding necessitate immediate operative treatment aimed at elimination of the involved segment.

Diverticular disease is characterised by inflammatory and bleeding complications. Diverticulitis may lead to peridiverticulitis and pericolitis with frank peritonitis. Uncomplicated diverticulosis warrants observation only under dietary guidance. Repeated complications indicate elective operation by one-stage-resection. Perforation, abscess and massive bleeding necessitate immediate operative treatment aimed at elimination of the involved segment. (orig.)

    A prospective cohort study with 100% follow-up. To assess incidence and risk factors for development of post-traumatic stress disorder (PTSD) symptoms after elective lumbar arthrodesis. Invasive medical care results in substantial physical and psychological stress to patients. The reported incidence of PTSD after medical care delivery in patients treated for trauma, cancer, and organ transplantation ranges from 5% to 51%. Similar data after elective lumbar spinal arthrodesis have not been reported. A consecutive series of 73 elective lumbar spine arthrodesis patients were evaluated prospectively, using the PTSD checklist-civilian version at 6 weeks, 3 months, 6 months, 9 months, and 12 months after surgery. Patient's sex, age, education level, job status, marital status, psychiatric history, prior surgery with general anesthetic, surgical approach, blood loss, postoperative intubation, length of intensive care unit and hospital stay, and occurrence of perioperative complications were analyzed as predictors of PTSD symptoms, using χ analyses. The overall incidence of symptoms of PTSD identified at at least 1 time point was 19.2% (14 of 73). At each time point, the percentage of the population that was positive was 7.5% (6 wk), 11.6% (3 mo), 7.8%, (6 mo), 13.6% (9 mo), and 11.0% (12 mo). The presence of a prior psychiatric diagnosis proved to be the strongest predictor of postarthrodesis symptoms of PTSD (odds ratio [OR] = 7.05, P = 0.002). Occurrence of a complication also proved to be significantly correlated with the development of PTSD symptoms (OR = 4.33, P = 0.04). Age less than 50 years, blood loss of more than 1 L, hospital stay of more than 10 days, and diagnosis trended toward but failed to reach statistical significance. None of the remaining variables approached statistical significance. Positive PTSD symptoms occurred at least once in 19.2% of patients after elective lumbar arthrodesis, with 7.5% to 13.6% of patients experiencing these symptoms at any 1

    Bronchial artery embolization is now a common treatment for massive pulmonary hemoptysis if flexible bronchoscopy at the bedside failed to control the bleeding. Complications of this technique range from benign chest pain to devastating neurological impairments. We report the case of a 41-year-old man who developed an ST elevation myocardial infarction during bronchial artery embolization, presumably because of coronary embolism by injected particles. In this patient who had no previously known coronary artery disease, we retrospectively found a communication between the left bronchial artery and the circumflex coronary artery. This fistula was not visible on the initial angiographic view and likely opened because of the hemodynamic changes resulting from the embolization. This case advocates for careful search for bronchial-to-coronary arterial fistulas and the need for repeated angiographic views during embolization procedures.

    The most common and serious complications of haemorrhoids include perianal thrombosis and incarcerated prolapsed internal haemorrhoids with subsequent thrombosis. They are characterised by severe pain in the perianal region possibly with bleeding. In a short history of the perianal thrombosis, acute surgical incision or excision is indicated, which can result in rapid relief of the painful symptoms. In incarcerated prolapsed internal haemorrhoids, emergency haemorrhoidectomy may also be indicated. Segmental haemorrhoidectomy in the most affected quadrants followed by further elective surgery for haemorrhoids in the next stage is preferred.

    Purpose: To evaluate left ventricular (LV) myocardial function in ten patients with coronary artery disease (CAD) preoperatively and 6 months after coronary bypass grafting (CABG) by cardiac MRI. Material and methods: Ten patients (mean 65.2±5.9 years) with angiographically proven CAD and an indication for elective CABG underwent prospective evaluation of global LV function and regional wall motion by Cine-MRI at rest using a multiphase FLASH-2D sequence following regions of interest (ROI)-defined diagnostics of regional myocardial wall motion by means of levocardiography. Within the ROIs a total of 613 LV myocardial segments were analyzed preceding and following surgical revascularization. Results were compared with the data of 10 healthy volunteers. Results: Preoperatively, patients showed reduced stroke volume and ejection fraction compared with volunteers (p [de

    Full Text Available Coronary arterial fistulas are rare communications between vessels or chambers of the heart. Although cardiac symptoms associated with fistulas are well described, fistulas are seldom considered in the differential diagnosis of acute myocardial ischemia. We describe the case of a 64-year-old man who presented with left shoulder pain, signs of heart failure, and a new left bundle branch block (LBBB. Cardiac catheterization revealed a small left anterior descending (LAD-to-pulmonary artery (PA fistula. Diuresis led to subjective improvement of the patient's symptoms and within several days the LBBB resolved. We hypothesize that the coronary fistula in this patient contributed to transient ischemia of the LAD territory through a coronary steal mechanism. We elected to observe rather than repair the fistula, as his symptoms and ECG changes resolved with treatment of his heart failure.

  9. A Rare and Serious Unforeseen Complication of Cutting Balloon Angioplasty

    2014-01-01

    Full Text Available Cutting balloon angioplasty (CBA is one of the adept ways of treating “in-stent restenosis.” Various complications related to cutting balloon angioplasty have been reported including arterial rupture, delayed perforation and fracture of microsurgical blades. Here we report a very unusual and inadvertent extraction of a stent previously deployed in the ramus intermedius coronary branch by a cutting balloon catheter. This required repeat stenting of the same site for an underlying dissection. Even though stent extraction is a rare complication it can be serious due to dissection, perforation, and closure of the artery. Physicians performing coronary artery interventions would need to be aware of this rare and serious complication especially if any difficulty is encountered while withdrawing the cutting balloon. Therefore, after removal, cutting balloon should be examined thoroughly for possible stent dislodgment or extraction when used for “in-stent restenosis.”

  10. Factors associated with mortality in patients undergoing coronary artery bypass grafting

    Full Text Available ABSTRACT Objective: to investigate the factors associated with mortality in patients undergoing coronary artery bypass grafting in a cardiovascular referral hospital in Santa Catarina. Method: quantitative, exploratory, descriptive and retrospective study. The medical records of 1447 patients, from 2005 to 2013, were analyzed for statistically related variables, these being: profile, hospitalization diagnosis, risk factors for coronary artery disease, complications recorded during the hospitalization, length of hospitalization and cause of death. Results: the mortality rate was 5.3% during the study period. Death was more common in females and those of black skin color, with a mean age of 65 years. Acute myocardial infarction was the most common hospitalization diagnosis. The majority of the complications recorded during hospitalization were characterized by changes in the cardiovascular system, with longer hospitalization periods being directly related to death from septic shock. Conclusion: the data provide subsidies for nursing work with preventive measures and early detection of complications associated with coronary artery bypass grafting. This reinforces the importance of using the data as quality indicators, aiming to guarantee care guided by reliable information to guide managers in planning patient care and high complexity health services.

Yet, of all elections that have taken place since the introduction of the multiparty system in 1990, the elections held on April 24 2016, were the most confusing. They were held early, but were neither a product of political, nor economic crisis. So why were they necessary?

    Percutaneous transluminal coronary angioplasty has grown exponentially since its introduction. Currently, selection criteria include single-vessel and multivessel disease, stable and unstable angina, and acute infarction. The outcome depends on specific patient and antiographic characteristics. In ideal lesions, success rates should be greater than 90%, with low morbidity and mortality. With more severe and diffuse multivessel disease, success rates are lower and complication rates are higher. In these cases, percutaneous transluminal coronary angioplasty still offers a reasonable option, provided complete revascularization can be achieved or the angina-producing lesion dilated. Numerous issues remain unresolved, including (1) the role of percutaneous transluminal coronary angioplasty vs coronary surgery (currently being tested), (2) restenosis, which occurs in approximately 30% of treated lesions, and (3) organizational adjustments such as training and certification to maintain high standards of care

    How competent a politician looks, as assessed in the laboratory, is correlated with whether the politician wins in real elections. This finding has led many to investigate whether the association between candidate appearances and election outcomes transcends cultures. However, these studies have largely focused on European countries and Caucasian candidates. To the best of our knowledge, there are only four cross-cultural studies that have directly investigated how face-based trait inferences correlate with election outcomes across Caucasian and Asian cultures. These prior studies have provided some initial evidence regarding cultural differences, but methodological problems and inconsistent findings have complicated our understanding of how culture mediates the effects of candidate appearances on election outcomes. Additionally, these four past studies have focused on positive traits, with a relative neglect of negative traits, resulting in an incomplete picture of how culture may impact a broader range of trait inferences. To study Caucasian-Asian cultural effects with a more balanced experimental design, and to explore a more complete profile of traits, here we compared how Caucasian and Korean participants’ inferences of positive and negative traits correlated with U.S. and Korean election outcomes. Contrary to previous reports, we found that inferences of competence (made by participants from both cultures) correlated with both U.S. and Korean election outcomes. Inferences of open-mindedness and threat, two traits neglected in previous cross-cultural studies, were correlated with Korean but not U.S. election outcomes. This differential effect was found in trait judgments made by both Caucasian and Korean participants. Interestingly, the faster the participants made face-based trait inferences, the more strongly those inferences were correlated with real election outcomes. These findings provide new insights into cultural effects and the difficult question of

    Complications of retained or entrapped equipment in the coronary system are still encountered during angioplasty procedures. Although these complications are rare, it is extremely difficult to retrieve such equipments. We report on two cases that a retained IVUS catheter or an entrapped filter wire were retrieved from the coronary system using more simplified technique that does not involve in the usage of snare or any other retrieval tool. After placing an additional guidewire and balloon alongside an equipment, it was easily retrieved from the coronary system just after the proximal balloon deflation. Copyright © 2012.

    Introduction Patients and their families are understandably anxious about the risk of complications and unfamiliar experiences following cardiac surgery. Providing information about postoperative care in the intensive care unit (ICU) to patients and families may lead to lower anxiety levels, and increased satisfaction with healthcare. The objectives of this study are to evaluate the effectiveness of preoperative patient education provided for patients undergoing elective cardiac surgery. Methods and analysis 100 patients undergoing elective coronary artery bypass graft, with or without valve replacement surgery, will be recruited into a 2-group, parallel, superiority, double-blinded randomised controlled trial. Participants will be randomised to either preoperative patient education comprising of a video and ICU tour with standard care (intervention) or standard education (control). The primary outcome measures are the satisfaction levels of patients and family members with ICU care and decision-making in the ICU. The secondary outcome measures are patient anxiety and depression levels before and after surgery. Ethics and dissemination Ethical approval has been obtained from the Joint Chinese University of Hong Kong—New Territories East Cluster Clinical Research Ethics Committee (reference number CREC 2015.308). The findings will be presented at conferences and published in peer-reviewed journals. Study participants will receive a 1-page plain language summary of results.

    The monorail technique allows monitoring of all steps of the coronary angioplasty procedure by high quality coronary angiography; easy, rapid, and safe recrossing and redilatation of the lesion if necessary; and stepwise dilatation of a stenosis with sequential increase of size of balloons. Transstenotic pressure differences cannot, however, be measured through the narrow shaft of the standard monorail balloon catheter. The monorail technique was used in 1014 patients (820 men, 194 women; mean age 57.8 years (range 24 to 84]. The indication for coronary angioplasty was stable angina in 52%, unstable angina in 40%, and acute myocardial infarction in 8%. Single vessel coronary angioplasty was attempted in 78%, multilesion coronary angioplasty in 11%, and multivessel coronary angioplasty in 11%. Angiographic success (reduction of stenosis to less than 50% of the luminal diameter) of all attempted lesions was achieved in 93%. The technique was clinically successful--that is, angiographic success of all attempted lesions, no occurrence of a major complication (death, myocardial infarction, acute bypass surgery), and improvement of symptoms--in 92% and partially successful in 1.3%. The clinical success rates were similar for stable angina (91%) and unstable angina (94%), but were somewhat lower for acute myocardial infarction (88%). Failure without major complication occurred in 3.4% of the patients. Failure with a major complication occurred in 3.3% (death 0.3%, myocardial infarction 2.4%, and acute bypass surgery 2.3%). The total major complication rate was higher in unstable angina (4.2%) than in stable angina (3.0%). These results indicate that the monorail technique can be applied safely and effectively for coronary angioplasty of patients with stable angina, unstable angina, and acute myocardial infarction.

  18. Role of depression in secondary prevention of Chinese coronary heart disease patients receiving percutaneous coronary intervention.

    Full Text Available Coronary heart disease (CHD patients who have undergone percutaneous coronary intervention (PCI have higher rates of depression than the general population. However, few researchers have assessed the impact of depression on the secondary prevention of CHD in China.The main purpose of this investigation was to explore the relationship between depression and secondary prevention of CHD in Chinese patients after PCI.This descriptive, cross-sectional one-site study recruited both elective and emergency PCI patients one year after discharge. Data from 1934 patients were collected in the clinic using questionnaires and medical history records between August 2013 and September 2015. Depression was evaluated by the 9-item Patient Health Questionnaire. Secondary prevention of CHD was compared between depression and non-depression groups.We found that depression affected secondary prevention of CHD in the following aspects: lipid levels, blood glucose levels, smoking status, physical activity, BMI, and rates of medication use.Depressive patients with CHD are at increased risk of not achieving the lifestyle and risk factor control goals recommended in the 2006 AHA guidelines. Screening should focus on patients after PCI because treating depression can improve outcomes by improving secondary prevention of CHD.

    Full Text Available Background. Tube thoracostomy is widely used throughout the medical, surgical, and critical care specialities. It is generally used to drain pleural collections either as elective or emergency. Complications resulting from tube thoracostomy can occasionally be life threatening. Aim. To present an update on the complications and management of complications of tube thoracostomy. Methods. A review of the publications obtained from Medline search, medical libraries, and Google on tube thoracostomy and its complications was done. Results. Tube thoracostomy is a common surgical procedure which can be performed by either the blunt dissection technique or the trocar technique. Complication rates are increased by the trocar technique. These complications have been broadly classified as either technical or infective. Technical causes include tube malposition, blocked drain, chest drain dislodgement, reexpansion pulmonary edema, subcutaneous emphysema, nerve injuries, cardiac and vascular injuries, oesophageal injuries, residual/postextubation pneumothorax, fistulae, tumor recurrence at insertion site, herniation through the site of thoracostomy, chylothorax, and cardiac dysrhythmias. Infective complications include empyema and surgical site infection. Conclusion. Tube thoracostomy, though commonly performed is not without risk. Blunt dissection technique has lower risk of complications and is hence recommended.

Material and methods. The study included 294 patients with coronary heart disease and its complications. The patients were divided into two groups. Group I included 89 patients with acute Q-myocardial infarction, which was placed in the presence of at least 2 of the following criteria identified on the basis of a comprehensive clinical and instrumental examination: clinical, laboratory confirmation (CK-MB, electrocardiographic signs of damage or myocardial necrosis. The following statistical methods were used: multi-variate and univariate analysis of variance, non-parametric tests, crosstabulation, chi-square test, Fisher»s exact test. As a measure of variability of the normal distribution standard deviation was used. Results. It is noted that in patients with myocardial infarction more likely than in patients without coronary heart attack in history severe generalized periodontitis, dentofacial anomalies and multiple dental caries have appeared. In patients with acute myocardial infarction, severe periodontal disease has been associated with increased fibrinogen levels in the blood and an increase in the dispersion of the interval QT, which are known to be indicators of poor prognosis in acute coronary disease.

    Summary: Spontaneous coronary artery dissection (SCAD) is an uncommon but important cause of acute coronary syndrome. The diagnosis of SCAD by an angiogram alone can be challenging and the increasing use of intracoronary imaging has proven an invaluable diagnostic adjunct in this regard. The appropriate initial management of SCAD has been a matter of significant debate. Owing to frequent spontaneous healing of coronary dissection and a higher risk of complications with percutaneous coronary intervention (PCI) in the setting of SCAD, a default approach of mechanical revascularization is not recommended. However in the presence of vessel occlusion and on-going myocardial infarction PCI is mandated. Bioresorbable vascular scaffolds (BVS) offer potential advantages over the conventional stents in the setting of SCAD. We describe a state-of-the-art approach to the acute treatment of SCAD causing STEMI, utilizing intravascular ultrasound (IVUS), optical coherence tomography (OCT) and BVS and discuss management strategies for the modern era. - Highlights: • SCAD is an infrequent but important cause of acute coronary syndrome. • Intracoronary imaging is a useful adjunct in the diagnosis of SCAD. • Revascularization is recommended in the presence on-going myocardial infarction. • BVS may be considered preferable to conventional stents in the setting of SCAD.

    The conventional treatment for isolated stenosis of the left main coronary artery is bypass surgery (myocardial revascularization). However, the process of atherosclerosis is not arrested by myocardial revascularization and it will lead to the occlusion of the left main coronary artery. Revascularization will establish retrograde perfusion for 50-70% of the myocardium of the left ventricle. Direct surgical angioplasty of the left main coronary artery enables normal physiological perfusion of the whole myocardium and better myocardial function. The aim of our study is to point out a new surgical approach of treating left main coronary artery stenosis. Between October 2002 and October 2003, direct surgical angioplasty of the main left coronary artery was performed on three patients with isolated stenosis of the left main coronary artery using the anterior approach and the pericardium as a patch. The procedure was performed under total endotracheal anaesthesia and standard cardiopulmonary circulation, moderate hypothermia, anterograde St. Tomas cardioplegia and local cooling. Patients were followed clinically, echocardiographically and by load-tests. All three patients were without complications. In postoperative follow-up (54-68 months) neither angina pectoris nor electrocardiographically registered ischaemic changes were found. Load-tests performed every six months on all three patients were negative. Surgical angioplasty of isolated stenosis of the left main coronary artery is a preferred method for treating this type of coronary disease. Contraindications for this type of treatment are stenosis of the left main coronary artery with bifurcation and advanced calcification of the left main coronary artery.

    Introduction Cardiopulmonary bypass (CPB) induces hemodilutional anemia, which frequently requires the transfusion of blood products. The objective of this study was to evaluate oxygen delivery and consumption and clinical outcome in low risk patients who were allocated to an hematocrit (Hct) of 20% versus 25% during normothermic CPB for elective coronary artery bypass graft (CABG) surgery. Methods This study was a prospective, randomized and controlled trial. Patients were subjected to normothermic CPB (35 to 36°C) and were observed until discharge from the intensive care unit (ICU). Outcome measures were calculated whole body oxygen delivery, oxygen consumption and clinical outcome. A nonparametric multivariate analysis of variance for repeated measurements and small sample sizes was performed. Results In a total of 54 patients (25% Hct, n = 28; 20% Hct, n = 26), calculated oxygen delivery (p = 0.11), oxygen consumption (p = 0.06) and blood lactate (p = 0.60) were not significantly different between groups. Clinical outcomes were not different between groups. Conclusion These data indicate that an Hct of 20% during normothermic CPB maintained calculated whole body oxygen delivery above a critical level after elective CABG surgery in low risk patients. The question of whether a transfusion trigger in excess of 20% Hct during normothermic CPB is still supported requires a larger prospective and randomized trial. PMID:16606474

    The advent of potent antiplatelet and antithrombotic agents over the past decade has resulted in significant improvement in reducing ischemic events in acute coronary syndrome (ACS). However, the use of antiplatelet and antithrombotic combination therapy, often in the settings of percutaneous coronary intervention (PCI), has led to an increase in the risk of bleeding. In patients with non-ST elevation myocardial infarction treated with antithrombotic agents, bleeding has been reported to occur in 0.4%–10% of patients, whereas in patients undergoing PCI, periprocedural bleeding occurs in 2.2%–14% of cases. Until recently, bleeding was considered an intrinsic risk of antithrombotic therapy, and efforts to reduce bleeding have received little attention. There have been increasing data demonstrating that bleeding is associated with adverse outcomes, including myocardial infarction, stroke, and death. Therefore, it is imperative to optimize patient outcomes by adopting pharmacological and nonpharmacological strategies to minimize bleeding while maximizing treatment efficacy. In this paper, we present a review of the bleeding classifications used in large-scale clinical trials in patients with ACS and those undergoing PCI treated with antiplatelets and antithrombotic agents, adverse outcomes, particularly mortality associated with bleeding complications, and suggested predictive risk factors. Potential mechanisms of the association between bleeding and mortality and strategies to reduce bleeding complications are also discussed. PMID:21915172

    2014-01-01

    Full Text Available Introduction. Entrapment and fracture of diagnostic or therapeutic devices within the coronary circulatory system are a rare, but increasing problem. Case report. A 70-yearold man was admitted in our clinic for coronary angiography before the planned aortic valve replacement. An arterial sheath was inserted in the right common femoral artery. After introducing a J-tip diagnostic coronary guidewire into the aorta and advancing a left Judkins diagnostic catheter over it, suddenly occured peeling off of the wire´s hydrophilic coating at the aortic arch level. Very soon, this outer coating of guidewire carried by the blood stream was entered into the left femoral artery, then into the left popliteal artery. This stripped part of guidewire was successfully caught and extracted out by using a goose-neck snare catheter. Conclusion. A sudden stripping of outer coating of a J-tip diagnostic hydrophilic coronary guidewire during coronary angiography is possible to manage quickly and successfully by the use of a simple cathether.

  10. Heart and coronary artery damage related to Kawasaki syndrome

    2014-01-01

    Full Text Available Kawasaki syndrome is an acute systemic vasculitis of unknown etiology, which mainly affects children within the first 5 years of fife. At the present time, Kawasaki syndrome is recognized to be a leading cause of acquired organic heart diseases in children, which may result in coronary heart disease, myocardial infarction, and sudden death in children and young people. Most complications are associated with the cardiovascular system, with coronary artery changes in particular. Transthoracic echocardiography, which, besides coronary artery assessment, makes it possible to evaluate right and left ventricular systolic and diastolic functions and to study the cardiac valves and changes in pericardial effusion, is a major technique in Kawasaki syndrome. The paper outlines an update on the epidemiology, etiology, pathogenetic mechanisms, and pathomorphology of Kawasaki syndrome and considers possible coronary and noncoronary changes, outcomes, and clinical manifestations.

    Mental stress-induced ischemia approximately doubles the risk of cardiac events in patients with coronary artery disease, yet the mechanisms underlying changes in coronary blood flow in response to mental stress are poorly characterized. Neuronal nitric oxide synthase (nNOS) regulates basal coronary blood flow in healthy humans and mediates mental stress-induced vasodilation in the forearm. However, its possible role in mental stress-induced increases in coronary blood flow is unknown. We studied 11 patients (6 men and 5 women, mean age: 58 ± 14 yr) undergoing elective diagnostic cardiac catheterization and assessed the vasodilator response to mental stress elicited by the Stroop color-word test. Intracoronary substance P (20 pmol/min) and isosorbide dinitrate (1 mg) were used to assess endothelium-dependent and -independent vasodilation, respectively. Coronary blood flow was estimated using intracoronary Doppler recordings and quantitative coronary angiography to measure coronary artery diameter. Mental stress increased coronary flow by 34 ± 7.0% over the preceding baseline during saline infusion (P coronary artery diameter by 6.9 ± 3.7% (P = 0.02) and 0.5 ± 2.8% (P = 0.51) in the presence of S-methyl-l-thiocitrulline. The response to substance P did not predict the response to mental stress (r2 = −0.22, P = 0.83). nNOS mediates the human coronary vasodilator response to mental stress, predominantly through actions at the level of coronary resistance vessels. NEW & NOTEWORTHY Acute mental stress induces vasodilation of the coronary microvasculature. Here, we show that this response involves neuronal nitric oxide synthase in the human coronary circulation.

    1986-01-01

    In 368 consecutive percutaneous transluminal coronary angiography (PTCA) procedures, acute occlusion of the dilated artery developed within the first hour after the procedure in 24 cases (6.5%). Four patients underwent emergency bypass surgery. In 17 of the remaining 20 patients, repeat balloon dilation was immediately attempted, and was successful in 11 instances (65%). Five of the six cases in which repeat balloon dilation was not successful responded well to surgical or medical therapy. The author conclude that acute occlusions of dilated coronary arteries shortly after PTCA do not automatically necessitate emergency bypass. Approximately two thirds of such cases can be managed by repeat dilation, converting a potential complication into a successful outcome

    Multinodular goitre is one of the commonest thyroid diseases encountered in the practice of surgery. The most common surgery being performed for multinodular goitre is subtotal thyroidectomy. Total thyroidectomy is designed to remove all of the thyroid tissue. The objective of this study was to evaluate total thyroidectomy as a primary elective procedure for treatment of multinodular thyroid disease. This descriptive study was carried out at Combined Military Hospital Rawalpindi from June 2003 to September 2006. 88 patients of multinodular thyroid disease were included. Patients having evidence of recurrent laryngeal nerve damage, recurrent goitre, evidence of altered parathyroid functions or evidence of malignancy were excluded. All patients underwent total thyroidectomy by the same team of surgeons and the patients were closely followed up for postoperative complications especially in terms of recurrent laryngeal nerve damage and hypocalcaemic tetany. No major postoperative complication was noted. Only 1 patient (1.14%) developed unilateral recurrent laryngeal nerve damage and 2 patients (2.27%) developed transient hypocalcaemia that recovered quickly. Total thyroidectomy as a primary elective procedure in multinodular thyroid disease is a safe option and it removes the disease process completely, lowers local recurrence rates and avoids the substantial risks of re operative surgery.

  18. Coronary angiography after successful thrombolysis - Is the recommended time interval of 24h an important issue?

    Science.gov (United States)

    Costa, Cátia; Durão, David; Belo, Adriana; Domingues, Kevin; Santos, Beatriz; Leal, Margarida

    2016-11-01

    Percutaneous coronary intervention (PCI) is currently considered the gold-standard treatment of acute coronary syndromes with ST-segment elevation (STEMI). However, this is not the reality of many European centers, where thrombolysis is performed as primary therapy. To determine, in a STEMI population that performed successful fibrinolytic treatment, if the performance of coronary angiography after the first 24h was associated with more hospital complications, including higher mortality, compared with its performance in the recommended time. Retrospective study, including 1065 patients with STEMI, who performed successful thrombolysis. The population was divided in three groups: A, patients who didn't undergo coronary angiography after successful thrombolysis (n=278; 26.1%); B, patients who underwent coronary angiography in the first 24h after successful thrombolysis (n=127; 11.9%); and C, patients who underwent angiography after the first 24h (n=660; 62.0%). Groups were compared regarding their characteristics and in-hospital complications. Groups B and C had more male patients and had younger patients than group A. Group A presented higher Killip classes at admission, more severe left ventricle dysfunction and a higher number of complications during hospitalization. Logistic regression revealed that: 1) the non-performance of coronary angiography after thrombolysis was an independent predictor of in-hospital mortality; and 2) the performance of angiography after the recommended time wasn't associated with higher mortality. Coronary angiography after thrombolysis constitutes an important strategy, whose non-performance carries worse prognosis. The time interval currently recommended of 24h seems clinically acceptable; however, its realization outside the recommended time doesn't seem to lead to higher mortality.

    Rupture and perforation of coronary arteries complicate in average 0.5% of radiosurgical coronary interventions and often are accompanied by serious consequences and high mortality. According to-type of coronary perforation different methods of correction are used, ranging from conservative measures to urgent cardiosurgical interventions. Coronary stent-grafts with 'sandwich' type of construction ore composed from two metal stents and PTFE layer between them. Development of such stents enabled effective radioguided endovascular repair of coronary ruptures. The paper presents the first Russian experience of stout-graft implantation for coronary artery rupture occurred during direct stenting of proximal anterior descending artery and balloon angioplasty in distal segment. The rupture occurred probably because of wall fragility between affected segment and muscular bridge. Stent-graft JoStent 16 mm in length connected with 3-mm balloon was implanted with subsequent complete restitution of blood flow, resolution of pain syndrome and ECG normalization. Echocardiography in operative theatre and one day after surgery showed no intrapericardial fluid. Stent-graft devices for urgent implantation in cases of coronary rupture must be included into obligatory equipment of radiosurgical facilities.

    Impella is a microaxial rotary pump that is placed across the aortic valve to expel aspirated blood from the left ventricle into the ascending aorta; it can be used in cardiogenic shock. While previous studies have evaluated the efficacy and safety of the Impella device, more clinically relevant data are necessary, especially with regard to outcomes. We screened our database of Impella patients in our heart center and found 68 consecutive patients who underwent Impella implantation due to acute coronary syndrome (ACS) complicated by cardiogenic shock. Data were evaluated with regard to baseline and procedural characteristics and also included an assessment of the short-term and long-term outcomes. The majority of patients (74%) suffered from an ST-elevation myocardial infarction, and 59% of patients received the Impella device during the initial coronary angiography. In the remaining cases, Impella implantation was performed at a later time, most commonly after IABP implantation. Patient characteristics were not significantly different between both groups. The predominantly implanted device was an Impella 2.5. Mortality in the severely ill patient population remained high, but univariate/multivariate analyses identified significant risk factors. Interestingly, delayed initiation of Impella support was an independent predictor of higher long-term mortality (hazard ratio, 2.157; P=.04) within the Impella patient cohort. This large series of patients with ACS complicated by cardiogenic shock who underwent Impella implantation provides information on the relevant risk factors for mortality. Early (compared with delayed) initiation of Impella support was a predictor of improved survival in this population of patients.

    Full Text Available On September 15, 2011 a record-high turn-out of 88 percent of the approx. 4 million Danes eligible to vote for the Danish parliament, the Folketing, was reached. This paper gives a short descriptive summary of the 2011 Danish election campaign. Irrespective of which side would win the position as primeminister, one thing was given: an exceptional era in Danish politics was coming to an end. After ten years of a Right Liberal-Conservative minority government supported by the Danish People's Party, Danish poli-tics would return to its classic modus operandi of centrist parties determining the prime-minister. By a margin of a few thousand votes, the red block won the elections and the new prime minister of Denmark is the Social Democrat Helle Thorning-Schmidt. This article describes the political context prior to the election campaign, the course of the election campaign, furthermore it presents the election results in a historical perspective and shortly discusses the challenges the new government is facing.

    2013-01-01

    Vascular Ehlers-Danlos syndrome is a rare connective tissue disorder associated with arterial dissection or rupture. Percutaneous coronary intervention (PCI) is often critical in patients with this syndrome because their coronary arteries are prone to dissection, enhancing the risk of stent borders dissection when conventional stent deployment pressures are used. Coronary artery bypass graft (CABG) treatment for these patients may also raise concerns because the left internal mammary artery is probably friable. Therefore, coronary artery revascularization in vascular Ehlers-Danlos syndrome either using PCI or CABG is challenging due to the arteries friability. A small number of cases have been published describing the friability of the vessels and associated complications; nevertheless, the optimum treatment remains unclear. We report the case of a 54-year-old woman treated successfully with PCI and CABG in two different acute coronary syndrome episodes, in which specific technical issues related to both procedures were decisive.

    The monorail Guidezilla guide extension catheter was designed to provide additional backup and facilitate device delivery in percutaneous coronary intervention (PCI) for complex coronary anatomy such as chronic total occlusion (CTO), extreme vessel tortuosity, diseased bypass grafts, and anomalous coronary arteries, among others.The present retrospective, single-center study included 188 consecutive patients who underwent PCI using the Guidezilla catheter from March 2015 to August 2016. Study outcomes were rates of target lesion crossing success, procedural success, and complications.The Guidezilla catheter was used most commonly in PCI of CTOs (45%) and heavy proximal calcification (37%), followed by tortuosity (10%), previously deployed proximal stents (4%), and coronary artery anomaly (4%). The right coronary artery (48%) was most commonly intervened followed by the left ascending (35%) and left circumflex (17%) arteries. Rates of target lesion crossing success and procedural success were both 99%, with one device-related periprocedural complication, namely proximal vessel dissection secondary to deep insertion which was successfully treated with stent implantation. Ninety percent of PCI were performed and completed successfully by radial access.In a single center with experienced operators, the use of the Guidezilla guide extension catheter in PCI of complex coronary anatomy performed mostly via radial artery access appeared safe and efficacious, and greatly facilitated device delivery.

    Coronary arterial abnormalities are uncommon findings in children that have profound clinical implications. Although anomalies of the coronary origins are well described, there are many other disease processes that affect the coronary arteries. Immune system-mediated diseases (eg, Kawasaki disease, polyarteritis nodosa, and other vasculiditides) can result in coronary arterial aneurysms, strictures, and abnormal tapering of the vessels. Because findings at imaging are an important component of diagnosis in these diseases, the radiologist's understanding of them is essential. Congenital anomalies may present at varying ages, and findings in hemodynamically significant anomalies, such as fistulas, are key for both diagnosis and preoperative planning. Pediatric heart surgery can result in wide-ranging postoperative imaging appearances of the coronary arteries and also predisposes patients to a multitude of complications affecting the heart and coronary arteries. In addition, although rare, accidental trauma can lead to injury of the coronary arteries, and awareness and detection of these conditions are important for diagnosis in the acute setting. Patients with coronary arterial conditions at presentation may range from being asymptomatic to having findings of myocardial infarction. Recognition of the imaging findings is essential to direct appropriate treatment. © RSNA, 2017.

    Full Text Available OBJECTIVE: To assess coronary stent placement in patients with multivessel coronary disease and involvement of the proximal portion of the anterior descending coronary artery. METHODS: We retrospectively analyzed the in-hospital and late evolution of 189 patients with multivessel coronary disease, who underwent percutaneous coronary stent placement. These patients were divided into 2 groups as follows: group I (GI - 59 patients with involvement of the proximal segment of the anterior descending coronary artery; and group II (GII - 130 patients without involvement of the proximal segment of the anterior descending coronary artery. RESULTS: No significant difference was observed in the success rate of the procedure (91.5% versus 97.6%, p=0.86, nor in the occurrence of major adverse cardiac events (5.1% versus 1.5%, p=0.38, nor in the occurrence of major vascular complications (1.7% versus 0%, p=0.69 in the in-hospital phase. In the late follow-up, the incidence of major adverse cardiac events (15.4% versus 13.7%, p=0.73 and the need for new revascularization (13.5% versus 10.3%, p=0.71 were similar for both groups. CONCLUSION: The in-hospital and late evolution of patients with multivessel coronary disease with and without involvement of the proximal segment of the anterior descending coronary artery treated with coronary stent placement did not differ. This suggests that this revascularization method is an effective procedure and a valuable option for treating these types of patients.

  11. Cultural effects on the association between election outcomes and face-based trait inferences.

    Directory of Open Access Journals (Sweden)

    Chujun Lin

    Full Text Available How competent a politician looks, as assessed in the laboratory, is correlated with whether the politician wins in real elections. This finding has led many to investigate whether the association between candidate appearances and election outcomes transcends cultures. However, these studies have largely focused on European countries and Caucasian candidates. To the best of our knowledge, there are only four cross-cultural studies that have directly investigated how face-based trait inferences correlate with election outcomes across Caucasian and Asian cultures. These prior studies have provided some initial evidence regarding cultural differences, but methodological problems and inconsistent findings have complicated our understanding of how culture mediates the effects of candidate appearances on election outcomes. Additionally, these four past studies have focused on positive traits, with a relative neglect of negative traits, resulting in an incomplete picture of how culture may impact a broader range of trait inferences. To study Caucasian-Asian cultural effects with a more balanced experimental design, and to explore a more complete profile of traits, here we compared how Caucasian and Korean participants' inferences of positive and negative traits correlated with U.S. and Korean election outcomes. Contrary to previous reports, we found that inferences of competence (made by participants from both cultures correlated with both U.S. and Korean election outcomes. Inferences of open-mindedness and threat, two traits neglected in previous cross-cultural studies, were correlated with Korean but not U.S. election outcomes. This differential effect was found in trait judgments made by both Caucasian and Korean participants. Interestingly, the faster the participants made face-based trait inferences, the more strongly those inferences were correlated with real election outcomes. These findings provide new insights into cultural effects and the

The coronary disease is the main cause of death in patients with diabetes mellitus. The stress myocardial perfusion imaging help diagnose diabetic coronary disease and prognosis judgement and risk assessment. So it can improve the living standard of patients with diabetes mellitus, and decrease the mortality of diabetes mellitus. (authors)

    To identify socio-demographic factors, characteristics and pregnancy complications associated with elective cesarean section. Cross-sectional study. A total of 1,295 births in the first semester of 2012 in Botucatu, São Paulo, Brazil, were evaluated in a large epidemiological study of maternal and child morbidity and mortality. This article compares women who had normal births (n = 405) with 214 undergoing elective cesarean section, defined as scheduled and without reference in hospital records or prenatal card of absolute, relative indication or any medical reason for that. Data were obtained from hospital records, prenatal card and interview with women, soon after parturition. Univariate analysis was conducted and evaluated by Fisher's exact or χ2 tests. Variables with p education, paid work and living with a partner) were independently associated with increased odds of elective cesarean section. Regardless of these, there was an association between elective caesarean section and prenatal and place of birth, with a higher chance of birth by elective caesarean section when the woman was assisted by the supplementary health network. Taking as indicators of unfavorable socioeconomic conditions the low education, the payment of prenatal and childbirth by the Unified Health System, it can be said that there was an association between elective caesarean section and better socio-economic conditions. Actions in the supplementary health network are required to approach the cesarean delivery rate in the municipality to the international recommendations.

    Full Text Available Abstract Background In off-pump coronary artery bypass surgery, manipulations on the beating heart can lead to transient interruptions of myocardial oxygen supply, which can generate an accumulation of oxygen-dependent metabolites in coronary venous blood. The objective of this study was to evaluate the reliability of intravascular near-infrared spectroscopy as a monitoring method to detect possible ischemic events in off-pump coronary artery bypass procedures. Methods In 15 elective patients undergoing off-pump myocardial revascularization, intravascular near-infrared spectroscopic analysis of coronary venous blood was performed. NIR signals were transferred through a fiberoptic catheter for signal emission and collection. For data analysis and processing, a miniature spectrophotometer with multivariate statistical package was used. Signal acquisition and analysis were performed before and after revascularization. Spectroscopic data were compared with hemodynamic parameters, electrocardiogram, transesophageal echocardiography and laboratory findings. Results A conversion to extracorporeal circulation was not necessary. The mean number of grafts per patient was 3.1 ± 0.6. An intraoperative myocardial ischemia was not evident, as indicated by electrocardiogram and transesophageal echocardiography. Continuous spectroscopic analysis showed reproducible absorption spectra of coronary sinus blood. Due to uneventful intraoperative courses, clear ischemia-related changes could be detected in none of the patients. Conclusion Our initial results show that intravascular near-infrared spectroscopy can reliably be used for an online intraoperative ischemia monitoring in off-pump coronary artery bypass surgery. However, the method has to be further evaluated and standardized to determine the role of spectroscopy in off-pump coronary artery bypass surgery.

    Full Text Available Coronary chronic total occlusion (CTO intervention remains one of the most challenging domains in interventional cardiology. Due to the technical challenges involved and potential procedural complications, CTO percutaneous coronary intervention (PCI attempt and success rates remain less than standard PCI. However, the use of several adjunctive tools such as intravascular ultrasound, optical coherence tomography, rotational atherectomy, orbital atherectomy, excimer laser coronary atherectomy and percutaneous left ventricular assist device may contribute to improved CTO PCI success rates or provide better hemodynamic assessment of CTO lesion (i.e., using fractional flow reserve. In this review we present the current literature describing the utility and efficacy of these adjunctive modalities in CTO intervention.

    Opium abuse is a major type of drug abuse in Iran. This study was designed to find the possible relation between opium addiction and excessive bleeding after coronary artery bypass graft (CABG) surgery. In a historical cohort study during a 1.5-year period, consecutive patients scheduled for elective CABG surgery were assigned to two group on the basis of having or not having the criteria for inhalational opium addiction. Before and after operations, the complete blood count, bleeding time, prothrombin time, partial thromboplastin time, and platelet count were checked for all patients. The volumes of infused red blood cells during and after the operation were recorded. After operations, the volumes of bleeding through the patients' chest tubes were recorded. The recorded data were analyzed using SPSS software version 11.5. Independent t, chi-square and repeated measure tests were used; and P Opium-addicted patients received more packed red blood cells during and after the operations. Inhalational opium addiction might lead to more hemorrhage after CABG surgery. It is recommended that cardiac surgeons consider these patients at high risk for major complications after surgery.

    Patients and their families are understandably anxious about the risk of complications and unfamiliar experiences following cardiac surgery. Providing information about postoperative care in the intensive care unit (ICU) to patients and families may lead to lower anxiety levels, and increased satisfaction with healthcare. The objectives of this study are to evaluate the effectiveness of preoperative patient education provided for patients undergoing elective cardiac surgery. 100 patients undergoing elective coronary artery bypass graft, with or without valve replacement surgery, will be recruited into a 2-group, parallel, superiority, double-blinded randomised controlled trial. Participants will be randomised to either preoperative patient education comprising of a video and ICU tour with standard care (intervention) or standard education (control). The primary outcome measures are the satisfaction levels of patients and family members with ICU care and decision-making in the ICU. The secondary outcome measures are patient anxiety and depression levels before and after surgery. Ethical approval has been obtained from the Joint Chinese University of Hong Kong-New Territories East Cluster Clinical Research Ethics Committee (reference number CREC 2015.308). The findings will be presented at conferences and published in peer-reviewed journals. Study participants will receive a 1-page plain language summary of results. ChiCTR-IOR-15006971.

    To test the Theory of Adherence of People with Chronic Disease with regard to adherence to treatment among patients with coronary heart disease after a percutaneous coronary intervention. Increased knowledge of the concept of adherence is needed for the development of nursing interventions and nursing guidelines for patients with coronary heart disease. A cross-sectional, multi-centre study. This study was conducted from February-December 2013 with 416 patients with coronary heart disease 4 months after undergoing a percutaneous coronary intervention. A self-reported questionnaire was used to assess their adherence to treatment. Data were analysed using structural equation modelling. The theory explained 45% of the adherence to a healthy lifestyle and 7% of the adherence to medication. Structural equation modelling confirmed that motivation and results of care had the highest association with adherence to a healthy lifestyle. Responsibility was associated with adherence to medication. Support from next of kin, support from nurses and physicians, and motivation, co-operation, fear of complications and a sense of normality were associated with adherence. Patients who are motivated to perform self-care and consider the results of care to be important were more likely to adhere to a healthy lifestyle. Responsible patients were more likely to adhere to their medication. It is important to account for these elements as a part of secondary prevention strategies among patients with coronary heart disease after a percutaneous coronary intervention. © 2015 John Wiley & Sons Ltd.

    The phase analysis was examined in 14 cases of COPD complicated with early cor pulmonale, 10 cases of coronary heart disease and 19 cases of normal subjects by the radionuclide gated blood pool imaging. Right heart catheterization was also performed in COPD group. It was shown that RVW (right ventricular phase angle width) in the COPD were significantly increased than that in the coronary heart disease group and the normal group, while LVW (left ventricular phase angle width) in the coronary heart disease group were significantly increased. It was worthy to be pointed out that in 3 of 4 cases of COPD with normal pulmonary artery pressure the RVW definitely prolonged. Therefore, it was suggested that RVW may be taken as an index for diagnosis of COPD complicated with early cor pulmonale

    The postoperative outcome after elective sigmoidectomy for diverticulitis has not been compared to that for cancer. The study aimed to evaluate the differences in the postoperative outcome after sigmoidectomy for diverticular disease and cancer. The National Inpatient Sample Database was used to identify patients who underwent elective sigmoid resection for diverticular disease or cancer between 2004 and 2011. After excluding patients with metastatic cancer and preoperative weight loss, sigmoid cancer and diverticulitis patients were matched using propensity score, controlling for age, gender, race, type of operation (open vs laparoscopic) and comorbidities. The end-points of interest were infective complications, reoperation, anastomotic leakage, rebleeding, length of hospital stay and in-hospital mortality. After propensity score matching (diverticulitis 11 192 patients, sigmoid cancer 11 192 patients), the mean age was 65 ± 12.5 years, 53.8% were male and 61.5% were Caucasian. Only 18.0% of the operations were done by laparoscopy. The overall complication rate was 17.7% and the in-hospital mortality rate was 0.9%. The diverticulitis group had a higher rate of surgical site infection (3.2% vs 2.6%, P = 0.004), intra-abdominal abscess formation (1.2% vs 0.4%, P diverticular disease has a higher risk of infective complications, elective sigmoidectomy for cancer has a higher risk of anastomotic leakage.

    Despite advancements in the creation and care of stomas, ostomy and peristomal skin complications are common immediately following surgery as well as in the months and years thereafter. A prospective study to determine the prevalence of ostomy and peristomal skin complications and the influence of ostomy configuration on such complications was conducted 1 year after ostomy surgery among all patients at a university hospital in Sweden. All participants received regular (10 to 14 days post discharge, 6 weeks, 3 months, 6 months, and 1 year post surgery) ostomy follow-up care by a wound ostomy continence (WOC) nurse. All consecutive elective and emergency patients who had undergone surgery to create a colostomy (end colostomy), end ileostomy, or loop ileostomy were eligible to participate. Patients who were reoperated during their first year post-surgery, patients with a urostomy, and patients with double ostomies were excluded from the study. Patient data collected included age, gender, diagnosis, elective or emergency surgery, open or laparoscopic surgical procedure, presence of a colorectal surgeon specialist at surgery, type of ostomy (colostomy, end ileostomy, loop ileostomy), preoperative ostomy siting, counseling, body mass index, American Society of Anesthesiologists classification, and radiation and/or chemotherapy status. Ostomies were evaluated by 4 WOC nurses as to stoma configuration, convexity use, patient self-sufficiency in stoma care, and complications. All 207 patients (53% women) who were eligible agreed to participate in the study. Patient median age was 70 years (range 19-94); 74% underwent elective surgery. Main diagnoses were colorectal cancer (62%) and inflammatory bowel disease (19%). Ostomy types were: colostomy (71%), end ileostomy (26%), and loop ileostomy (3%). One or more complications occurred in 35% of the patients (27% ostomy complications, 11% peristomal skin complications). A colostomy hernia was the most common surgical complication

    Full Text Available The thrombus formation in the left ventricle (LV cavity is a frequent complication of myocardial infarction (MI as well as a risk factor for peripheral arterial embolism. Probability of intraventricular thrombus depends on MI location and its therapy. A case of coronary embolism in a patient with anterior MI and thrombus in the LV aneurysm is considered in details. Successful percutaneous coronary intervention (PCI in the first 90 minutes after admission was performed. Decision to appoint a three-component antithrombotic therapy (acetylsalicylic acid, clopidogrel, warfarin was made on the 4th day of disease onset taking into account the combination of MI, stent placement in the anterior interventricular artery and the presence of left ventricular aneurysm with parietal thrombus. Recurrence of MI developed on the 9th day of disease onset. Aspiration thromboembolectomy was performed taking into account thrombosis of two coronary arteries. Warfarin therapy was discontinued in connection with subsequent clot lysis and development of not intensive nosebleed. Subsequent MI course was uneventful. In conclusion, even in spite of the timely achievement of PCI and early reperfusion, MI course can be complicated by thrombosis of the left ventricle and subsequent development of thromboembolic complications.

    The obesity epidemic is associated with a rise in coronary surgeries because obesity is a risk factor for coronary artery disease. Bariatric surgery is linked to improvement in cardiovascular co-morbidities and left ventricular function. No studies have investigated survival advantage in postoperative bariatric patients after coronary surgery. To determine if there is a benefit after coronary surgery in patients who have previously undergone bariatric surgery. National Inpatient Sample. We performed a retrospective, cross-sectional analysis of the National Inpatient Sample database from 2003 to 2010. We selected bariatric surgical patients who later underwent coronary surgery (n = 257). A comparison of postoperative complications and mortality after coronary surgery were compared with controls (n = 1442) using χ 2 tests, linear regression analysis, and multivariate logistical regression models. A subset population was identified as having undergone coronary surgery (n = 1699); of this population, 257 patients had previously undergone bariatric surgery. They were compared with 1442 controls. The majority was male (67.2%), white (82.6%), and treated in an urban environment (96.8%). Patients with bariatric surgery assumed the risk of postoperative complications after coronary surgery that was associated with their new body mass index (BMI) (BMI999.9, 95% CI .18 to>999.9, P = .07). Length of stay was significantly longer in postbariatric patients (BMIbariatric patients have a return to baseline risk of morbidity and mortality after coronary surgery.

    2014-01-01

    Preoperative colostomy presents a significant risk of sternal wound complications, mediastinitis, and ostomy injury in patients requiring coronary artery bypass grafting. Less invasive procedures in coronary surgery have a potential to reduce the risk of sternal wound healing problems. Robotic totally endoscopic coronary artery bypass grafting in patients with a colostomy has not been reported. We describe a case of completely endoscopic coronary surgery using the da Vinci Si system in a patient with a transverse colostomy. Single left internal mammary artery grafting to the left anterior coronary artery was performed successfully on the beating heart. We regard this technique as the least invasive method of surgical coronary revascularization with a potential to reduce the risk of surgical site infection and mediastinitis in patients with a colostomy.

    Full Text Available Fractional flow reserve (FFR has been recognized as an effective tool to determine functional significance in intermediate coronary lesions and FFR-guided percutaneous coronary intervention (PCI improves clinical outcomes. However, hemodynamic interaction between serial stenoses within one coronary artery complicates the assessment of functional severity of each individual lesion. We present a case in which FFR measurement by intracoronary bolus injection of adenosine helps to make appropriate revascularization decision in serial stenoses when the procedures are performed systemically and properly.

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

    The aim of this study was to investigate the risk factors for access site-related complications after transradial coronary angiography (CAG) or percutaneous coronary intervention (PCI). Transradial PCI has been shown to reduce access site-related bleeding complications compared with procedures performed through a femoral approach. Although previous studies focused on risk factors for access site-related complications after a transfemoral approach or transfemoral and transradial approaches, it is uncertain which factors affect vascular complications after transradial catheterization. We enrolled 500 consecutive patients who underwent transradial CAG or PCI. We determined the incidence and risk factors for access site-related complications such as radial artery occlusion and bleeding complications. Age, sheath size, the dose of heparin and the frequency of PCI (vs. CAG) were significantly greater in patients with than without bleeding complications. However, body mass index (BMI) was significantly lower in patients with than without bleeding complications. Sheath size was significantly higher and the frequency of statin use was significantly lower in patients with than without radial artery occlusion. Multiple logistic analysis revealed that sheath size [odds ratio (OR) 5.5; P strategy that could prevent radial artery occlusion after transradial procedures.

    2012-01-01

    Full Text Available Finding an untreated or asymptomatic large ventricular septal defect (VSD in an elderly patient is uncommon. The present case was an 81-year-old man who suffered from acute myocardial infarction due to three-vessel coronary disease, mitral and tricuspid valve insufficiency, and high-flow perimembranous VSD (Qp/Qs 2.3. Although the patient was elderly and the VSD had been asymptomatic for a long time, we considered that high-flow VSD and valve diseases should be repaired simultaneously with coronary disease. Then, he underwent elective surgery, namely, VSD patch repair concomitant with coronary artery bypass grafting, and mitral and tricuspid annuloplasty. His postoperative course was uneventful. We conclude that, even for an octogenarian, surgical repair of VSD is recommendable, if surgical indications are appropriate.

The revascularization of the posterior coronary arteries had the following distribution: diagonalis artery (31 patients, 10%; marginal branches of the circumflex artery (243 patients, 78.7%; posterior ventricular artery (4 patients, 1.3%; and posterior descending artery (31 patients, 10%. RESULTS: Procedure-related complications without death occurred in 7 cases, giving a morbidity of 2.5%. There were 11 deaths in the early postoperative period (mortality of 3.9%. CONCLUSION: Similarly to the anterior coronary arteries, the posterior coronary arteries may benefit from myocardial revascularization without CPB.

    Full Text Available This paper analyses the concepts of brand equity and brand value as found in the professional scientific literature and proposes an innovative research approach of the brand value of uninominal candidates running in the local elections in Romania in 2012 or of any other candidates that run in similar elections in terms of voting procedures. The originality of the paper consists in the fact that we have created a formula that will be used to measure the brand equity of these candidates depending on the results obtained by the party whose candidate is running in the elections, as compared to the other candidates and the other parties. This paper presents the methodology used to validate these formulae for measuring the theoretical score that should have been reached by a party’s candidate whose brand equals zero. In order to identify the contribution of the candidate’s brand to the respective result in our future research, we will make the difference and calculate the ratio between the real score and this theoretical score for a null personal brand. The present research, conducted from a positive perspective, resorts to a behavioural approach that allowsfor the measurement of the personal brand of candidates running for elections in certain electoral systems. This research is valuable for professionals as well as one can identify the candidates that are unsuitable for future elections, since a negative brand equity, accompanied by increased awareness (reached during the most recent elections, at the latest can hardly be turned into a positive image. Moreover, this analysis can be used in the internal assessments conducted by each political party after elections.

    This systemic review evaluated the efficacy and safety of Chinese herbal medicines (CHMs) in patients with coronary heart disease (CHD) complicated with depression. All databases were retrieved till September 30, 2014. Randomized controlled trials (RCTs) comparing CHMs with placebo or conventional Western medicine were retrieved. Data extraction, analyses and quality assessment were performed according to the Cochrane standards. RevMan 5.3 was used to synthesize the results. Thirteen RCTs enrolling 1,095 patients were included. Subgroup analysis was used to assess data. In reducing the degree of depression, CHMs showed no statistic difference in the 4th week [mean difference (MD)=-1.06; 95% confidence interval (CI)-2.38 to 0.26; n=501; I(2)=73%], but it was associated with a statistically significant difference in the 8th week (MD=-1.00; 95% CI-1.64 to-0.36; n=436; I(2)=48%). Meanwhile, the combination therapy (CHMs together with antidepressants) showed significant statistic differences both in the 4th week (MD=-1.99; 95% CI-3.80 to-0.18; n=90) and in the 8th week (MD=-5.61; 95% CI-6.26 to-4.97; n=242; I(2)=87%). In CHD-related clinical evaluation, 3 trials reported the intervention group was superior to the control group. Four trials showed adverse events in the intervention group was less than that in the control group. CHMs showed potentially benefits on patients with CHD complicated with depression. Moreover, the effect of CHMs may be similar to or better than antidepressant in certain fields but with less side effects. However, because of small sample size and potential bias of most trials, this result should be interpreted with caution. More rigorous trials with larger sample size and higher quality are warranted to give high quality of evidence to support the use of CHMs for CHD complicated with depression.

    Objective: To evaluate the effects on postoperative pulmonary function of pleural integrity versus opened pleura, in patients who receive a left internal mammary artery graft. Study Design: Randomized control trial. Place and Duration of study: Armed Forces Institute of Cardiology and National Institute of Heart Diseases, Rawalpindi from June 2009 to Feb 2010. Patients and Methods: The study was conducted on 62 patients who underwent elective coronary artery bypass grafting. The patients were divided into 2 groups: Group A consisted of patients who underwent internal mammary artery harvesting with opened pleura (n=31) while Group B consisted of patients having internal mammary artery harvested with intact pleura (n=31). To monitor pleuro-pulmonary complications, chest radiography was performed routinely 1 day before operation and on the second, fourth and sixth postoperative days. The preoperative, after extubation, and first postoperative day values of partial oxygen pressure (PaO/sub 2/), partial carbon dioxide pressure (PaCO/sub 2/), oxygen (O/sub 2/) saturation and haematocrit were recorded for comparison. The effect of intact pleura on IMA traction was also recorded by serial cardiac enzymes measurement and electrocardiography in the immediate postoperative period. Results: Pleural effusion occurred more often in patients of Group A (35.5% versus 12.9%) which was statistically significant (P 0.038). However, no significant differences were recorded in postoperative respiratory complications. Reoperation for postoperative bleeding and tamponade was done in 6.5% and 3.2% of cases in Group B respectively but none Group A; however it was not statistically significant (P 0.076). The mean postoperative hospital stay was 7.84 days for Group A and 7.58 days for Group B. Conclusion: Pleural integrity during IMA harvesting decreases pleural effusion. Although, no significant differences were recorded in postoperative lung complications, intact pleural technique of IMA

    Full Text Available Abstract The Legal Institution of the General Election in Indonesia has an important role in the process of elections to realize the sovereignty of the people. The legal institution is independent as mandated of the Indonesian constitution The 1945 Constitution. In the Election organizers as a chapter of the 1945 Constitution stating that the Election Commission shall be independent and impartial toward participating in the election and political party. However in practice this task is not easy and can be run smoothly it is difficult to maintain a balanced relationship between the participant election commissions. This research is a descriptive analytic one using juridical normative approach to study the legal principles legal synchronization. The technique being used to gather data is librarian research supported by field research using interview and questionnaire technique. The data being gathered are analyzed qualitatively. The result of the research shows that the legal institution the general election in undertaking has not been independent as expected because for institutional and administrative for has not been independence and not impartiality and not professionalism. The rules in the process of elections is it not the election system and achievement of justice.

    Coronary artery fistulas represent the most common hemodynamically significant congenital defect of the coronary arteries and the clinical presentation is mainly dependent on the severity of the left-to-right shunt. We describe a case of a 55-year-old man with history of chest pain and without history of previous significant chest wall trauma or any invasive cardiac procedures. A coronary multislice computed tomography showed two large coronary fistulas arising from the left anterior descending coronary artery and ending in an angiomatous plexus draining into the common pulmonary trunk. Coronary angiography confirmed the CT finding and showed a third fistulous communication arising from the sinus node artery. Although coronary fistulas are infrequent, they are becoming increasingly important because their management and treatment could prevent serious complications. The latest guidelines of the American College of Cardiology/American Heart Association indicate as Class I recommendation the percutaneous or surgical closure for large fistulas regardless of symptoms. In this manuscript, we provide a detailed review of the literature on this topic, focusing on the clinical management of these patients.

    Metabolic syndrome (MS) is associated with increased incidence of diabetes and atherosclerotic complications. The new definition of the International Diabetes Federation (IDF) increases the population with this entity, compared to the NCEP ATP III definition. To study the prevalence of coronary artery disease (CAD) and carotid intima-media thickness (IMT) in patients with and without MS, according to the NCEP ATP III and IDF definitions, and the predictive ability of carotid IMT for CAD. We studied 270 consecutive patients admitted for elective coronary angiography due to suspicion of CAD. All patients underwent ultrasound study of the carotid arteries to measure IMT (the highest value between the right and left common carotid arteries was used in the analysis). Coronary stenosis of > or =70% (or 50% for the left main coronary artery) was considered significant. By the ATP III definition, 14% of the patients had MS, and these patients had a higher prevalence of CAD (87% vs. 63%, p = 0.004), but no significant difference was found for carotid IMT (1.03 +/- 0.36 mm vs. 0.95 +/- 0.35 mm, p=NS). With the IDF definition, 61% of the patients had MS; this group was slightly older and included more women. There were no differences in terms of CAD (68% vs. 63%) or carotid IMT (0.97 +/- 0.34 vs. 0.96 +/- 0.39 mm). On multivariate analysis, the ATP III definition of MS predicts CAD (OR 4.76, 95% CI 1.71-13.25, p = 0.003), but the IDF definition does not (OR 1.29, 95% CI 0.74-2.27, p = 0.37). On ROC curve analysis, an IMT of > or = 0.95 mm predicts CAD (AUC 0.66, p definition increases the population with MS, decreasing the capacity to predict the presence of CAD. In our population, neither the ATP III nor the IDF definition showed differences in terms of carotid IMT. Carotid IMT can predict CAD, but with only modest sensitivity.

    2010-12-01

    Full Text Available Elections to the European Parliament (EP are considered second-order national elections (SOE. The SOE model suggests that there is a qualitative difference between different types of elections depending on the perception of what is at stake. Compared to first order elections, in second order elections there is less at stake because they do not determine the composition of government. Given that voters behave differently in second-order elections, the question arises: do the media also consider second-order elections less interesting and therefore devote to them less coverage? The media play a crucial role in informing citizens about such events as elections; they function as intermediaries between the electorate and the political arena. However, little is known about how EU issues are covered in the media, particularly in the new EU member states. Conducting a content analysis and applying the second-order election model, this paper analyses TV news coverage of the 2004 and 2009 European elections in the Czech Republic and Slovakia in a comparative fashion. The findings are discussed in the light of existing research literature on the EU’s legitimacy as well as its alleged democratic and communication deficit, not least because the EU relies on the media in strengthening (albeit indirectly its legitimacy by increasing citizen awareness of its activities.

    Noncardiac surgery after percutaneous coronary intervention (PCI) has been reported to be carrying high risk for both ischemic and bleeding complications. However, there has been no report comparing the incidence and outcomes of surgical procedures after coronary artery bypass grafting (CABG) with those after PCI. Among 14 383 patients undergoing first coronary revascularization (PCI, n=12 207; CABG, n=2176) enrolled in the Coronary Revascularization Demonstrating Outcome Study in Kyoto (CREDO-Kyoto) PCI/CABG Registry Cohort-2, surgical procedures were performed more frequently after CABG (n=560) than after PCI (n=2398; cumulative 3-year incidence: 27% versus 22%; unadjusted PPCI groups (cumulative incidence: 3.1% versus 3.2%; unadjusted P=0.9; adjusted hazard ratio, 0.97; 95% confidence interval, 0.47-1.89; P=0.9). The risk for the primary bleeding outcome measure (moderate or severe bleeding by Global Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded Coronary Arteries classification) was lower in the CABG groups than in the PCI group (cumulative incidence: 1.3% versus 2.6%; unadjusted P=0.07; adjusted hazard ratio, 0.36; 95% confidence interval, 0.12-0.87; P=0.02). There were no interactions between the timing of surgery and the types of coronary revascularization (CABG/PCI) for both ischemic and bleeding outcomes. Surgical procedures were performed significantly more frequently after CABG than after PCI, particularly PCI were associated with similar risk for ischemic events and lower risk for bleeding events, regardless of the timing after coronary revascularization. © 2014 American Heart Association, Inc.

    The retrograde approach through collaterals has been applied in the treatment of chronic total occlusion (CTO) lesions during percutaneous recanalization of coronary arteries. This study was to investigate the success rate of recanalization and collateral related complications in patients when using the retrograde approach. Eighty-four cases subjected to retrograde approach identified from July 2005 to July 2012 were included in this study. Patient characteristics, procedural outcomes and in-hospital clinical events were evaluated. Mean age of the patient was (59.6 ± 11.2) years old and 91.7% were men. The target CTO lesions were distributed among the left anterior descending artery in 45 cases (53.5%), left circumflex artery in one case (1.2%), right coronary artery in 34 cases (40.5%), and left main in four cases (4.8%). The overall success rate of recanalization was 79.8%. The septal collateral was three times more frequently used for retrograde access than the epicardial collateral, 68/84 (81%) vs. 16/84 (19%). Successful wire passage through the collateral channel was achieved in 58 (72.6%) patients. The success rate of recanalization was 93.1% (54/58) in patients with and 50% (13/26) in patients without successful retrograde wire passage of the collateral channel (P collaterals was achieved in 49 of 68 septal collaterals (72.1%) and in 9 of 16 epicardial collaterals (56.3%) (P = NS). There was no significant difference between the septal collateral group and the epicardial group in the success rate of recanalization after retrograde wire crossing the collaterals (91.8% vs. 100%, P > 0.05). CART or reverse CART technique was used in 15 patients, and 14 patients (93.3%) were recanalized successfully. Collateral related perforation occurred in three (18.8%) cases with the epicardial collateral as the first choice (compared with the septal collateral group (0), P collaterals.

    Ventricular repolarization dynamics (VRD) is an important predictor of outcome in diabetes. We examined the potential impact of coronary artery disease (CAD) on VRD in type 2 diabetic patients. We recorded 5-min high-resolution resting electrocardiograms (ECG) in 38 diabetic patients undergoing elective coronary angiography, and in 38 age- and gender- matched apparently healthy subjects (Controls). Using leads I and II, time-domain indices of VRD were calculated. Coronary angiography was regarded as positive if a 350% stenosis was found. Angiography was positive in 21 diabetic patients (55%). Patients with CAD had a significantly higher degree of VRD than Controls (SDNN(QT): 15.81+/-7.22 ms vs. 8.94+/-6.04 ms; P <0.001, rMSSD(QT): 21.02k7.07 ms vs. 11.18k7.45 ms; P <0.001). VRD in diabetic patients with negative angiograms did not differ from VRD in Controls (SDNN(QT): 8.94+/-6.04 ms vs. 7.44+/-5.72 ms; P=0.67, rMSSD(QT): 11.18+/-7.45 ms vs. 10.22+/-5.35 ms; P=O. 82). CAD increases VRD in patients with type 2 diabetes. Therefore, changes in ventricular repolarization in diabetic patients may be due to silent CAD rather than to diabetes per se.

    Coronary artery aneurysm (CAA) is an uncommon clinical finding, with an incidence varying from 1.5%-4.9% in adults, and is usually considered a variant of coronary artery disease (CAD). CAA identified in the context of acute coronary syndrome (ACS) represents a unique management challenge, particularly if the morphology of the CAA is suspected to have provoked the acute clinical syndrome. CAA is associated with thrombus formation due to abnormal laminar flow, as well as abnormal platelet and endothelial-derived pathophysiologic factors within the CAA. Once formed, mural thrombus may potentiate the deposition of additional thrombus within aneurysmal segments. Percutaneous revascularization of CAA has been associated with complications including distal embolization of thrombus, no-reflow phenomenon, stent malapposition, dissection, and rupture. Presently, there are no formal guidelines to direct the management of CAA in patients presenting with ACS; controversies exist whether conservative, surgical, or catheter-based management should be pursued. In this manuscript, we present an extensive review of the existing literature and associated clinical guidelines, and propose a management algorithm for patients with this complex clinical scenario. Armed with this perspective, therapeutic decisions may be tailored to synthesize patient factors and preferences, individualized clinical assessment, and existing American Heart Association/American College of Cardiology guidelines for management of ACS.

    Purpose: This retrospective study was undertaken to evaluate the effectiveness of coronary stent placement in hepatic artery stenosis after orthotopic liver transplantation (OLT). Materials and methods: Of 430 consecutive adult orthotopic liver transplant recipients between November 2003 and September 2005, 17 had hepatic artery stenosis (HAS). Fourteen of them underwent coronary stent placement in the HAS. The technical results, complications, hepatic artery patency and clinical outcome were reviewed. Results: Technical and immediate success was 100%. After a mean follow-up of 159.4 days (range, 9-375 days), all patients obtained patent hepatic arteries except 2 patients occurred hepatic artery restenoses at 26 and 45 days after stent placement, respectively. Kaplan-Meier curve of patency showed cumulated stent patency at 3, 6, and 12 months of 78%, 58% and 45%, respectively. During the follow-up, 8 patients survived, 5 died of septic multiple-organ failure, 1 received retransplantation because of refractory biliary infection. Hepatic artery dissection induced by a guiding catheter occurred in one patient and was successfully treated with a coronary stent. Conclusion: Hepatic artery stenosis after OLT can be successfully treated with coronary stent placement with low complication rate and an acceptable 1-year hepatic artery patency rate

    Von Willebrand disease (vWD) results from quantitative or qualitative deficiency of von Willebrand factor (vWF). The occurrence of myocardial infarction is very rare in patients with vWD. A few case reports of acute coronary syndrome (ACS) in vWD patients are present in the literature, but no definite management recommendations are available for such patients. We report a case of successful percutaneous coronary intervention (PCI) with bare-metal stent (BMS) implantation in a 46-year-old woman with type 1 vWD and history of coronary artery disease (CAD). She received periprocedural dual-antiplatelet therapy for 2 weeks and then continued aspirin without any bleeding complications. The optimal management of patients with vWD and ACS is complex and presents a therapeutic challenge. We propose that dual-antiplatelet therapy can be used safely in most vWD patients presenting with ACS as most of them are type 1 vWD. PCI with BMS can be done safely. Long-term management of these patients requires a systemic approach including hematological consultation, ascertaining vWF levels, as well as patient education and close outpatient follow-up.

    Directory of Open Access Journals (Sweden)

    JM Greben

    2006-06-01

    Full Text Available A novel model has been developed to predict elections on the basis of early results. The electorate is clustered according to their behaviour in previous elections. Early results in the new elections can then be translated into voter behaviour per cluster and extrapolated over the whole electorate. This procedure is of particular value in the South African elections which tend to be highly biased, as early results do not give a proper representation of the overall electorate. In this paper we explain the methodology used to obtain the predictions. In particular, we look at the different clustering techniques that can be used, such as kmeans, fuzzy clustering and k-means in combination with discriminant analysis. We assess the performances of the different approaches by comparing their convergence towards the final results.

    Objective: To evaluate the role of angiocadiography (ACG) in the diagnosis and management of complex/complicated congenital heart disease (CHD). Methods: A retrospective study of ACG findings in 360 cases with complex/complicated CHD was performed with a comparision to that of echocardiography (Echo) and related clinical examination. Results: The present series of CHD cases included pulmonary atresia with ventricular septal defect in 75 cases, double outlet of right ventricle in 62 cases, Fallot's tetralogy in 60 cases, single ventricle in 52 cases, transposition of the great arteries in 42 cases, tricuspid valve atresia in 15 cases, coronary abnormality in 6 eases, total abnormal pulmonary venous connection in 5 cases, total endocardial cushion defect in 5 cases, persistent truncus arteriosus in 4 cases, pulmonary atresia with normal ventricular septum in 3 cases, other disorders in 7 eases, and postsurgical operation in 24 cases. ACG was superior to that of Echo in demonstrating the abnormalities of systemic, pulmonary, and coronary arteries and their branches of complex/complicated CHD as well as measuring the pressure of pulmonary artery, vein, and systemic-pulmonary collateral vessels. Conclusion: In the diagnosis and differential diagnosis of knotty cases with complex and complicated CHD, particularly in the demonstration of full view of systemic, pulmonary, and coronary arterial branches and accurate measurement of' pulmonary arterial pressure/resistance, and atrial, ventricular, and systemic arterial pressure, ACG (including DSA) still plays an important and irreplaceable role.

    Objective: To investigate the characteristic changes of myocardial perfusion imaging and coronary artery angiography in patients of acute myocardial infarction (AMI) with underlined type 2 diabetes mellitus. Methods: 25 type 2 diabetes mellitus patients were enrolled for having clinical manifestation of AMI. Ten inpatients with AMI of simple coronary heart disease origin were served as controls. All subjects underwent both myocardial perfusion imagings (resting and nitroglycerine invention) and coronary artery angiography. Results: Compared to controls (40%), type 2 diabetes mellitus + AMI group had higher rate of multivessel disease (60%). For type 2 diabetes mellitus + AMI patients, 129/400 segments (32.25%) showed fixed defect, 25/160 segments (15.62%) in controls. Conclusions: For type 2 diabetes mellitus + AMI group, myocardial perfusion defects are widely distributed and multivessel or severe stenosis is more often presented. Good correlation exists between abnormal segments and angiographic lesions in both the number of segments involved and the severity of the lesions. Radionuclide myocardial perfusion is therefore considered a useful screening test not inferior to angiography, especially for those who are not tolerant enough to undergoing angiography

    Electivity indices measure the utilization of food types (r) in relation to their abundance or availability in the environment (p). Foods that constitute a larger proportion of the diet than of the available foods are considered preferred; conversely those proportionately underrepresented in the diet are avoided. A food is eaten at random if its proportion in the diet equals its proportion in the environment. A family of electivity indices stemming from Ivlev's (1961) classic monograph exist and differ only in the particular algorithm used to calculate electivity from r and p.For each available index I graphed the values of electivity as contours for all combinations of r and p. These graphs are compared to illustrate the strengths and weaknesses of each index on the basis of the following criteria: 1) the value of the index when r=p for a food, 2) the symmetry of the electivity value as feeding deviates from random, 3) the possible range of index values, 4) the linearity of changes in electivity over the full range of r and p, 5) the sensitivity of the index to sampling errors, 6) the statistical testability of the electivity, and 7) the stability of the electivity value for a food type that changes relative abundance or occurs in combination with different food types. No one index ideally satisfies all the criteria.The host preferences of gypsy moth, Lymantria dispar, feeding on tree foliage in an undisturbed deciduous forest in southwestern Quebec, Canada were used to compare the available indices: Ivlev's electivity, E; Ivlev's forage ratio, E'; Jacob's modified electivity, D; Jacob's modified forage ratio, log Q; Chesson's alpha; Strauss' linear index, L; and Vanderploeg and Scavia's relativized electivity, E * . The electivity values calculated by each index differ one from another; host trees shown as preferred by one index will frequently appear avoided according to an alternative index. The rank order electivities for the 19 available host trees, however

    In some opinions, opium consumption has traditionally been considered to be a means to lower blood lipids and to put off heart diseases. In this study, the relationship between opium consumption and risk factors of coronary artery diseases, hemodynamic factors and cardiac related functions before and after surgery was evaluated. In a cross-sectional study 325 patient's candidate for elective coronary artery bypass grafting were enrolled in a period of 6 months. Opium addicted patients were recognized based on taking history from the patients by an anaesthesiologist. Serum lipid profile was determined at the beginning of the study. Frequency and distribution of coronary artery diseases were assessed according to the pre-operative coronary angiography. From 325 patients, 117 patients were opium abusers and 208 patients were not. Mean duration of opium abuse was 12.6 ± 7.7 years. Mean total serum cholesterol levels were not significantly different in abusers and non-users patients (185 ± 47 vs. 190 ± 49, P > 0.05). Mean level of low-density lipoprotein cholesterol was significantly higher in addicted group (121 ± 27 vs. 81 ± 22, P opium addicted cases. Mean body mass index was also lower in addicted patients significantly (25.3 ± 3.7 vs. 27.5 ± 4.1, P opium abuse and aggravating lipid profile and hypercholesterolemia and coronary artery disease.

    BACKGROUND: Conventional coronary artery bypass grafting performed with the use of cardiopulmonary bypass is a well-validated treatment for patients with ischemic heart disease. Off-pump coronary artery bypass grafting (OPCAB) has been suggested to reduce the number of perioperative complications......, especially in elderly patients. METHODS AND RESULTS: In a multicenter, randomized trial, we assigned 900 patients >70 years of age to conventional coronary artery bypass grafting or OPCAB surgery. After 30 days, a blinded end-point committee assessed whether a combined end point of death, stroke...... experiencing the combined end point within 30 days was 10.2% for conventional coronary artery bypass grafting and 10.7% for OPCAB. Implied risk difference of 0.4% (with a 95% confidence interval, -3.6 to 4.4) showed nonsignificance in a standard test for equality (P=0.83) and for noninferiority...

    Coronary artery and peripheral occlusive arterial disease frequently complicate diabetes mellitus, with death due to atherosclerotic coronary artery disease being three times more likely in diabetic compared to non-diabetic patients. The profile of 32 diabetic patients and 32 matched controls who underwent coronary artery bypass (CABG) is studied and their early and late postoperative outcomes are described. The mean age was 61 +\\/- 1 year in both groups. The diabetic group comprised 26 non-insulin dependent and 6 insulin dependent diabetics, who had a mean duration of diabetes of 8.5 years (range 2 months--35 years). The median number of grafts per patient performed in the diabetic group and the control group was 3.5 and 3 respectively. There was no mortality in the series, however considerably greater wound morbidity rates were encountered in the diabetic group when compared to matched controls. One renal transplant patient in the diabetic group suffered irreversible acute tubular necrosis and became dialysis dependent post-operatively. Longterm follow-up showed no longterm mortality in either group, with full relief of angina achieved in 75% of diabetic patients compared with 87.5% of matched controls. In addition diabetic patients suffered greater longterm cardiac morbidity than the control group (21.8% versus 12.5%). The results of this study suggest that CABG is a safe operation for the diabetic patient. Diabetic patients receive satisfactory symptomatic relief of angina, but suffer increased perioperative wound complications and greater incidence of longterm cardiac morbidity.

    Individuals with childhood-onset coronary artery anomalies are at increased risk of lifelong complications. Although pregnancy is thought to confer additional risk, a few data are available regarding outcomes in this group of women. We sought to define outcomes of pregnancy in this unique population. We performed a retrospective survey of women with paediatric-onset coronary anomalies and pregnancy in our institution, combined with a systematic review of published cases. We defined paediatric-onset coronary artery anomalies as congenital coronary anomalies and inflammatory arteriopathies of childhood that cause coronary aneurysms. Major cardiovascular events were defined as pulmonary oedema, sustained arrhythmia requiring treatment, stroke, myocardial infarction, cardiac arrest, or death. A total of 25 surveys were mailed, and 20 were returned (80% response rate). We included 46 articles from the literature, which described cardiovascular outcomes in 82 women (138 pregnancies). These data were amalgamated for a total of 102 women and 194 pregnancies; 59% of women were known to have paediatric-onset coronary artery anomalies before pregnancy. In 23%, the anomaly was unmasked during or shortly after pregnancy. The remainder, 18%, was diagnosed later in life. Major cardiovascular events occurred in 14 women (14%) and included heart failure (n=5, 5%), myocardial infarction (n=7, 7%), maternal death (n=2, 2%), cardiac arrest secondary to ventricular fibrillation (n=1, 1%), and stroke (n=1, 1%). The majority of maternal events (13/14, 93%) occurred in women with no previous diagnosis of coronary disease. Women with paediatric-onset coronary artery anomalies have a 14% risk of adverse cardiovascular events in pregnancy, indicating the need for careful assessment and close follow-up. Prospective, multicentre studies are required to better define risk and predictors of complications during pregnancy.

    Coronary heart disease and its management continue to be at the centre of Government health policy. The present political climate demands clinical effectiveness and best practice should be established, while maintaining the philosophy of cost-effectiveness and resource management. These directives have led practitioners to question the care of patients following coronary artery bypass surgery, in particular the role of mechanical ventilation and the subsequent act of extubation. A retrospective study of 89 patients who had coronary artery bypass grafts (emergency and elective) was undertaken, to establish if extubation had a significant effect on the haemodynamic status of patients with variable degrees of left ventricular function (19% with poor left ventricular function). The study found that extubation was achieved within a mean time of 4.97 hours following return from surgery. Extubation resulted in a significant increase in heart rate (P = 0.001), as well as a respiratory acidosis (pCO2: P = 0.000; pH: P = 0.000). However, the stability of the patient was not compromised, with neither mean arterial blood pressure (P = 0.825) nor oxygenation levels (P = 0.267) being significantly altered by extubation. On multivariate analysis, the act of extubation had no significant effect on any of the dependent variables. These results suggest that it is not extubation alone that has an impact on the haemodynamic stability of patients following coronary artery bypass grafts, but that this is indeed multifactorial. Therefore extubation is 'safe' practice for patients with varying degrees of left ventricular function following coronary artery bypass grafts. Limitations of the study are acknowledged.

    Objective: To ascertain the current status of global health training and humanitarian relief opportunities in US and Canadian postgraduate neurology programs. Background: There is a growing interest among North American trainees to pursue medical electives in low- and middle-income countries. Such training opportunities provide many educational and humanitarian benefits but also pose several challenges related to organization, human resources, funding, and trainee and patient safety. The current support and engagement of neurology postgraduate training programs for trainees to pursue international rotations is unknown. Methods: A survey was distributed to all program directors in the United States and Canada (December 2012–February 2013) through the American Academy of Neurology to assess the training opportunities, institutional partnerships, and support available for international neurology electives. Results: Approximately half of responding programs (53%) allow residents to pursue global health–related electives, and 11% reported that at least 1 trainee participated in humanitarian relief during training (survey response rate 61%, 143/234 program directors). Canadian programs were more likely to allow residents to pursue international electives than US programs (10/11, 91% vs 65/129, 50%, p = 0.023). The number of trainees participating in international electives was low: 0%–9% of residents (55% of programs) and 10%–19% of residents (21% of programs). Lack of funding was the most commonly cited reason for residents not participating in global health electives. If funding was available, 93% of program directors stated there would be time for residents to participate. Most program directors (75%) were interested in further information on global health electives. Conclusions: In spite of high perceived interest, only half of US neurology training programs include international electives, mostly due to a reported lack of funding. By contrast, the majority

    To assess the influence of calcified plaque characteristics on the overestimation of coronary arterial stenosis on a coronary CT angiography (CCTA). The study included 271 coronary arteries with calcified plaques identified by CCTA, and based on 928 coronary arteries from 232 patients who underwent both CCTA and invasive coronary angiography (ICA). Individual coronary arteries were classified into two groups by agreement based on the degree of stenosis from each CCTA and ICA: 1) group A includes patients with concordant CCTA and ICA results and, 2) group B includes patients with an overestimation of CCTA compared to ICA. Parameters including total calcium score, calcium score of an individual coronary artery, calcium burden number of an individual coronary artery, and the density of each calcified plaque (calcium score / number of calcium burden) for each individual coronary artery were compared between the two groups. Of the 271 coronary arteries, 164 (60.5%) were overestimated on CCTA. The left anterior descending artery (LAD) had a significantly low rate of overestimation (47.1%) compared to the other coronary arteries (p=0.001). No significant differences for total calcium score, calcium score of individual coronary artery, and the density of each calcified plaque from individual coronary arteries between two groups was observed. However, a decreasing tendency for the rate of overestimation on CCTA was observed with an increase in calcium burden of individual coronary arteries (p<0.05). The evaluation of coronary arteries suggests that the degree of coronary arterial stenosis had a tendency to be overestimated by calcified plaques on CCTA. However, the rate of overestimation for the degree of coronary arterial stenosis by calcified plaques was not significantly influenced by total calcium score, calcium score of individual coronary artery, and density of each calcified plaque

    Full Text Available Abstract Introduction The potential of alcohol withdrawal to cause acute coronary events is an area that needs the urgent attention of clinicians and researchers. Case presentation We report the case of a 52-year-old heavy-alcohol-using Sri Lankan man who developed electocardiogram changes suggestive of an acute coronary event during alcohol withdrawal. Despite the patient being asymptomatic, subsequent echocardiogram showed evidence of ischemic myocardial dysfunction. We review the literature on precipitation of myocardial ischemia during alcohol withdrawal and propose possible mechanisms. Conclusions Alcohol withdrawal is a commonly observed phenomenon in hospitals. However, the number of cases reported in the literature of acute coronary events occurring during withdrawal is few. Many cases of acute ischemia or sudden cardiac deaths may be attributed to other well known complications of delirium tremens. This is an area needing the urgent attention of clinicians and epidemiologists.

  14. Acute Thrombosis after Elective Direct Intracoronary Stenting in Primary Antiphospholipid Syndrome: A Case Report

    2003-04-01

    Full Text Available Antiphospholipid syndrome (APS is an uncommon prothrombotic disorder that has been increasingly recognized in recent years. The diagnosis of APS must be associated with venous or arterial thrombosis or both. Patients with APS usually present with recurrent deep vein thrombosis, pulmonary thromboembolism, thromboembolic stroke, or myocardial infarction. Here, we report a case of a 61-year-old female who presented with a 3-month history of increasingly frequent retrosternal chest tightness. After treadmill test and thallium-201 myocardial perfusion scan, she was admitted and underwent elective coronary angiography but developed acute thrombosis after direct intracoronary stenting. She was successfully rescued with repeat percutaneous transluminal coronary angioplasty and prolonged heparin and glycoprotein IIb/IIIa antagonist use. Laboratory data showed prolongation of partial thromboplastin time and positive anti-cardiolipin antibody. These findings satisfied the criteria for APS; the patient was diagnosed with primary APS because she had neither typical symptoms nor signs of systemic lupus erythematosus or other immunologic disorders. Thereafter, long-term oral anticoagulant appeared to be effective. To our knowledge, this is the first report of acute stent thrombosis in a patient with primary APS.

    Traditionally, patients are kept nil-per-os/nil-by-mouth (NPO/NBM) prior to invasive cardiac procedures, yet there exists neither evidence nor clear guidance about the benefits of this practice. To demonstrate that percutaneous cardiac catheterisation does not require prior fasting. The data source is a retrospective analysis of data registry of consecutive patients who underwent percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) and stable angina at two district general hospitals in the UK with no on-site cardiac surgery services. A total of 1916 PCI procedures were performed over a 3-year period. None of the patients were kept NPO/NBM prior to their coronary procedures. The mean age was 67±16 years. 1349 (70%) were men; 38.5% (738/1916) had chronic stable angina, while the rest had ACS. 21% (398/1916) were diabetics while 53% (1017/1916) were hypertensive. PCI was technically successful in 95% (1821/1916) patients. 88.5% (1697/1916) had transradial approach. 77% (570/738) of elective PCI patients were discharged within 6 h postprocedure. No patients required emergency endotracheal intubation and there were no occurrences of intraprocedural or postprocedural aspiration pneumonia. Our observational study demonstrates that patients undergoing PCI do not need to be fasted prior to their procedures.

  16. Bayesian inference on proportional elections.

    Directory of Open Access Journals (Sweden)

    Gabriel Hideki Vatanabe Brunello

    Full Text Available Polls for majoritarian voting systems usually show estimates of the percentage of votes for each candidate. However, proportional vote systems do not necessarily guarantee the candidate with the most percentage of votes will be elected. Thus, traditional methods used in majoritarian elections cannot be applied on proportional elections. In this context, the purpose of this paper was to perform a Bayesian inference on proportional elections considering the Brazilian system of seats distribution. More specifically, a methodology to answer the probability that a given party will have representation on the chamber of deputies was developed. Inferences were made on a Bayesian scenario using the Monte Carlo simulation technique, and the developed methodology was applied on data from the Brazilian elections for Members of the Legislative Assembly and Federal Chamber of Deputies in 2010. A performance rate was also presented to evaluate the efficiency of the methodology. Calculations and simulations were carried out using the free R statistical software.

    2003-01-01

    Coronary artery disease (CAD) was evaluated by noninvasive examination in abdominal aortic aneurysm (AAA) patients. A simultaneous operation or a 2-staged operation was performed depending on the seriousness of the condition when both diseases were combined. A total of 36 patients underwent elective repair of AAA between 1996 and 2001. Coronary angiography (CAG) was performed only in patients with suspected CAD by dipyridamole myocardial scintigraphy. Significant CAD was found in 8 patients. Simultaneous operation was performed in 4 patients, and off-pump coronary artery bypass grafting (OPCAB) was performed in all cases of simultaneous operation. In 4 patients receiving 2-staged operations, 1 standard coronary artery bypass grafting (CABG), 1 OPCAB and 2 percutaneous transluminal coronary angioplasties (PTCA) were performed prior to AAA surgery. Twenty-eight patients underwent only AAA operation. Though there were no incidents of perioperative myocardial infarction or cardiac related deaths in this group, 2 patients died due to other causes (hemorrhage and duodenal perforation). In the 8 patients associated with CAD, 1 patient died of myonephrotic metabolic syndrome (MNMS) after simultaneous operation. The other 7 patients revived their social function soon of the discharge. Dipyridamole cardiac scintigraphy was considered to be an effective examination for evaluation of CAD in AAA patients. There was no need to perform CAG in all AAA patients. The policy of choosing simultaneous operation or 2-staged operation according to the seriousness of the 2 diseases seemed to be appropriate. (author)

    Gender differences among patients with the acute coronary syndrome is still being debated, no research has been done on gender inequality among coronary syndrome patients in Sudan. To study gender differences in presentation, management, and outcomes of acute coronary syndrome in Sudan. This cross-sectional descriptive longitudinal study was conducted in Omdurman Teaching Hospital between July 2014 and August 2015. Patients were invited to sign a written informed consent form, were interviewed and examined by a physician, and then followed during their hospital stay. Information collected includes coronary risk factors, vital signs, echocardiography findings, arrhythmias, heart failure, cardiogenic shock, and death. The Ethical Committee of Omdurman Teaching Hospital approved the research. A total of 197 consecutive acute coronary syndrome patients were included, 43.1% were females. A significant statistical difference was evident between males and females regarding the type of acute coronary syndrome, its presentation, and time of presentation to the hospital, smoking, and receipt of thrombolysis (P 0.05). Women were less likely to receive thrombolytic therapy, present with chest pain, and diagnosed with ST-segment elevation myocardial infarction. No gender differences were found in acute coronary syndrome risk factors apart from smoking, which was more common in males, and there were no differences between males and females as regards in-hospital complications.

    To test the hypothesis that the 3-hydroxy-3-methylglutaryl coenzyme-A reductase inhibitor pravastatin ameliorates endothelium mediated responses of dilated coronary segments: the PREFACE (pravastatin related effects following angioplasty on coronary endothelium) trial. A double blind, randomised, placebo controlled, multicentre study. Four hospitals in the Netherlands. 63 non-smoking, non-hypercholesterolaemic patients scheduled for elective balloon angioplasty (pravastatin 34, placebo 29). The effects of three months of pravastatin treatment (40 mg daily) on endothelium dependent vasomotor function were studied. Balloon angioplasty was undertaken one month after randomisation, and coronary vasomotor function tests using acetylcholine were performed two months after balloon angioplasty. The angiograms were analysed quantitatively. The efficacy measure was the acetylcholine induced change in mean arterial diameter, determined in the dilated segment and in an angiographically normal segment of an adjacent non-manipulated coronary artery. Increasing acetylcholine doses produced vasoconstriction in the dilated segments (p = 0.004) but not in the normal segments. Pravastatin did not affect the vascular response to acetylcholine in either the dilated segments (p = 0.09) or the non-dilated sites. Endothelium dependent vasomotion in normal segments was correlated with that in dilated segments (r = 0.47, p < 0.001). There were fewer procedure related events in the pravastatin group than in the placebo group (p < 0.05). Endothelium dependent vasomotion in normal segments is correlated with that in dilated segments. A significant beneficial effect of pravastatin on endothelial function could not be shown, but in the dilated segments there was a trend towards a beneficial treatment effect in the pravastatin group.

    To analyse the effect of mechanical bowel preparation vs no mechanical bowel preparation on outcome in patients undergoing elective colorectal surgery. Meta-analysis of randomised controlled trials and observational studies comparing adult patients receiving mechanical bowel preparation with those receiving no mechanical bowel preparation, subdivided into those receiving a single rectal enema and those who received no preparation at all prior to elective colorectal surgery. A total of 36 studies (23 randomised controlled trials and 13 observational studies) including 21568 patients undergoing elective colorectal surgery were included. When all studies were considered, mechanical bowel preparation was not associated with any significant difference in anastomotic leak rates (OR = 0.90, 95%CI: 0.74 to 1.10, P = 0.32), surgical site infection (OR = 0.99, 95%CI: 0.80 to 1.24, P = 0.96), intra-abdominal collection (OR = 0.86, 95%CI: 0.63 to 1.17, P = 0.34), mortality (OR = 0.85, 95%CI: 0.57 to 1.27, P = 0.43), reoperation (OR = 0.91, 95%CI: 0.75 to 1.12, P = 0.38) or hospital length of stay (overall mean difference 0.11 d, 95%CI: -0.51 to 0.73, P = 0.72), when compared with no mechanical bowel preparation, nor when evidence from just randomized controlled trials was analysed. A sub-analysis of mechanical bowel preparation vs absolutely no preparation or a single rectal enema similarly revealed no differences in clinical outcome measures. In the most comprehensive meta-analysis of mechanical bowel preparation in elective colorectal surgery to date, this study has suggested that the use of mechanical bowel preparation does not affect the incidence of postoperative complications when compared with no preparation. Hence, mechanical bowel preparation should not be administered routinely prior to elective colorectal surgery.

    Limited data describe risks and perioperative resource needs of total joint arthroplasty (TJA) in dialysis-dependent patients. Retrospective multiple cohort analysis of dialysis-dependent American College of Surgeons National Surgical Quality Improvement Program patients undergoing primary elective total hip and knee arthroplasty compared to non-dialysis-dependent controls from 2005 to 2015. Relative risks (RRs) of 30-day adverse events were determined by multivariate regression adjusting for baseline differences. Six hundred forty-five (0.2%) dialysis-dependent patients of 342,730 TJA patients were dialysis-dependent and more likely to be dependent, under weight, anemic, hypoalbuminemic, and have cardiopulmonary disease. In total hip arthroplasty patients, dialysis was associated with greater risk of any adverse event (RR = 1.1, P care unit (ICU) care (RR = 9.8, P total knee arthroplasty patients, dialysis conferred greater risk of any adverse event (RR = 1.1, P care (RR = 6.0, P care, longer admission, and rehabilitation needs in TJA patients. Thirty days is not sufficient to detect infectious complications among these patients. These findings inform shared decision-making, perioperative resource planning, and risk adjustment under alternative reimbursement models. Copyright © 2018 Elsevier Inc. All rights reserved.

    Full Text Available Coronary artery ectasia (CAE is characterized by inappropriate dilatation of the coronary vasculature. The mechanisms of CAE are not well known. Insulin-like growth factor-1 (IGF-1 may make endothelial cells and smooth muscle cells more sensitive to the effects of growth hormone. In the present study, we hypothesized that IGF-1 may have an impact on the formation of ectasia and aneurysm in arterial system, and aimed to investigate the associations between the presence of CAE and serum IGF-1 levels in patients undergoing coronary angiography. The study included 2.980 subjects undergoing elective diagnostic coronary angiography. We selected 40 patients diagnosed with CAE as CAE group and 44 subjects with absolutely normal coronary arteries were assigned as normal control group. IGF-1 levels were measured in both groups of patients. Groups were similar in terms of age, sex and coronary artery disease risk factors. The serum IGF-1 levels were significantly higher in CAE patients with 109.64±54.64 ng/mL than in controls with 84.76±34.01 ng/mL (p=0.016. HDL levels were lower in ectasia group with 41.5±10.7 mg/dL than controls with 47.7±10.4 mg/dL (p=0.018. By means of logistic regression analysis, high IGF-1 and low HDL levels were found to be independent risk factors for the presence of CAE (p<0.02, p<0.016, respectively. The study revealed that there was a positive correlation between serum IGF-1 levels and presence of CAE, and high IGF-1 levels and low HDL levels were independent risk factors for the presence of CAE. Future studies are needed to confirm these results.

    2012-06-01

    Full Text Available Due to the ageing population and raised life expectancy, elderly patients are increasingly referred for percutaneous coronary intervention (PCI during acute coronary syndromes (ACS. Bleeding complications are not infrequent during ACS, occurring in 2-5% of patients with prognostic and economic consequences. In particular, periprocedural bleeding and vascular complications are associated with worse clinical outcome, prolonged hospital stay and increased short- and long-term mortality, especially in elderly patients with acute coronary syndromes. We report the case of an 83-year old female referred to our hospital because of non-ST segment elevation myocardial infarction with high bleeding risk and unsuitable radial artery undergoing transulnar sheathless PCI during bivalirudin infusion. The clinical, technical, pharmacological and prognostic implications are discussed.

    2018-01-01

    BACKGROUND: Surgical site infection (SSI) and other postoperative complications are associated with high costs, morbidity, secondary surgery, and mortality. Many studies have identified factors that may prevent SSI and pulmonary complications, but it is important to know when they in fact occur....... The aim of this study was to investigate the diagnostic timing of surgical site infections and pulmonary complications after laparotomy. MATERIAL AND METHODS: This is a secondary analysis of the PROXI trial which was a randomized clinical trial conducted in 1400 patients undergoing elective or emergent...... laparotomy. Patients were randomly allocated to either 80% or 30% perioperative inspiratory oxygen fraction. RESULTS: SSI or pulmonary complications were diagnosed in 24.2% (95% CI: 22.0%-26.5%) of the patients at a median of 9 days [IQR: 5-15] after surgery. Most common was surgical site infection (19...

    2008-01-01

    Background: Coronary vasospasm is defined as a temporary, intense narrowing of the coronary conduit artery. It brings about ischemic chest pain and becomes one of the causes of myocardial infarction. Coronary spasms are divided into two categories. One is the coronary spasm of the conduit artery and the other is the coronary microvascular spasm. Although coronary spasms are diagnosed with the images of coronary angiography, microvascular spasms cannot be diagnosed because of the limitations of conventional angiographic systems. However, synchrotron radiation coronary angiography (SRCA) can identify coronary arteries down to 100 μm in diameter in the beating heart and 50 μm in arrested heart. Aim: The purpose of this study was to confirm whether microvascular spasms could be identified or not using SRCA, and then down that size identification was possible. Methods: The Langendorff perfusion system with isolated rat hearts was employed. Krebs-Henseleit solution (KH solution) was used as a perfusate. 10 mM of 4-aminopyridine (4-AP: a voltage-gated potassium channel blocker; spasm inducer) was added to the KH solution and maintained for 5 min. SRCA was performed at pre-, during and 10 min after cessation of the KH solution with 4-AP. Coronary spasms were defined as a temporal 75% reduction of coronary arterial diameter. Results and conclusion: Multiple sizes of coronary arteries showed coronary spasms. The minimum stenosed coronary artery size was 100 μm. Since coronary microvascular spasms are seen in the arterioles (50-400 μm), coronary microvascular spasms may be diagnosed with the use of synchrotron radiation coronary angiography

    Akinori Fujikake

    2016-01-01

    Full Text Available A 66-year-old man was admitted to our institute because of chest pain. He had undergone replacement of the ascending aorta due to aortic dissection 9 years previously. We made a diagnosis of acute coronary syndrome, and coronary artery angiography was performed. Although the right coronary artery was successfully cannulated, a severe bend of the artificial aorta made it very difficult to advance the catheter into the left coronary artery. Ultimately, a DIO thrombus aspiration catheter was used to enter the left coronary artery, and a stent was implanted successfully. The DIO catheter is very useful when the selection of a guiding catheter is complicated, such as in the case of severe vessel tortuosity or a bend of the ascending aorta.

  10. Comparison of Early Outcomes with Three Approaches for Combined Coronary Revascularization and Carotid Endarterectomy

    Directory of Open Access Journals (Sweden)

    Arzu Antal Dönmez

    Full Text Available Abstract Objective: This study aims to compare three different surgical approaches for combined coronary and carotid artery stenosis as a single stage procedure and to assess effect of operative strategy on mortality and neurological complications. Methods: This retrospective study involves 136 patients who had synchronous coronary artery revascularization and carotid endarterectomy in our institution, between January 2002 and December 2012. Patients were divided into 3 groups according to the surgical technique used. Group I included 70 patients who had carotid endarterectomy, followed by coronary revascularization with on-pump technique, group II included 29 patients who had carotid endarterectomy, followed by coronary revascularization with off-pump technique, group III included 37 patients who had coronary revascularization with on-pump technique followed by carotid endarterectomy under aortic cross-clamp and systemic hypothermia (22-27ºC. Postoperative outcomes were evaluated. Results: Overall early mortality and stroke rate was 5.1% for both. There were 3 (4.3% deaths in group I, 2 (6.9% deaths in group II and 2 (5.4% deaths in group III. Stroke was observed in 5 (7.1% patients in group I and 2 (6.9% in group II. Stroke was not observed in group III. No statistically significant difference was observed for mortality and stroke rates among the groups. Conclusion: We identified no significant difference in mortality or neurologic complications among three approaches for synchronous surgery for coronary and carotid disease. Therefore it is impossible to conclude that a single principle might be adapted into standard practice. Patient specific risk factors and clinical conditions might be important in determining the surgical tecnnique.

  11. Effect of pretreatment with omega-3 polyunsaturated fatty acids (PUFAs on hematological parameters and platelets aggregation in patients during elective coronary artery bypass grafting

    2013-01-01

    Full Text Available Bacground/Aim. Using omega-3 polyunsaturated fatty acids (PUFAs in coronary artery bypass graft surgery (CABG could provide protection against ischemicreperfusion damage, prevention of postoperative arrhythmia and attenuation of inflammatory response. However, omega-3 PUFAs inhibit cyclooxygenase (and thus decrease the synthesis of thromboxane A2 from arachidonic acid in platelets, which leads to decreased platelet aggregation. In cardiac surgery it is necessary to achieve a balance between inhibition and full platelets function. It is as well as important to closely follow hematological parameters, impaired by CABG itself. Therefore, the aim of the study was to establish the effects of pretreatment with omega- PUFAs on hematological parameters and plateletes aggregation in patients with elective CABG. Methods. This prospective, randomized, placebo-controlled, single-center trial was performed on parallel groups. The patients (n = 40 undergoing elective CABG were randomized receiving preoperative intravenous omega-3 PUFAs (Omegaven® 10% infusion (the PUFAs group or the same volume of 0.9% saline solution infusion (the control group. Infusion was given a day before surgery and repeated four hours before starting extracorporeal circulation (CPB via the peripheral vein at single doses of 100 mL (25 mL/h. Platelet function analysis was performed using multiple electrode aggregometry (MEA, multiplate-analyzer before starting CPB and 2 h postoperatively for the patients of both groups. Results. There were no clinically relevant differences in baseline characteristics between the groups. Hematological parameters were not significantly different between the groups pre-, intra- and postoperatively. During the first 24 h after surgery, the loss of blood was similar in the PUFAs and the control group (680 ± 274 mL and 608 ± 210 mL, respectively; p = 0.356. Postoperatively, platelet aggregation was not significantly different between the PUFAs and the

    2012-01-31

    BACKGROUND: Elective open infrarenal Abdominal Aortic Aneurysm (AAA) repair is major surgery performed on high-risk patients. Routine ICU admission postoperatively is the current accepted standard of care. Few of these patients actually require a level of care that cannot be provided just as effectively in a surgical high dependency unit (HDU). Our aim was to determine, \\'can high risk patients that will require ICU admission postoperatively be reliably identified preoperatively?\\'. METHODS: A retrospective analysis of all elective open infrarenal AAA repairs in our institution over a 3-year period was performed. The Estimation of Physiological Ability and Surgical Stress (E-PASS) model was used as our risk stratification tool for predicting post-operative morbidity. Renal function was also considered as a predictor of outcome, independent of the E-PASS. RESULTS: 80% (n = 16) were admitted to ICU. Only 30% (n = 6) of the total study population necessitated intensive care. There were 9 complications in 7 patients in our study. The E-PASS comprehensive risk score (CRS)\\/Surgical stress score (SSS) were found to be significantly associated with the presence of a complication (p = 0.009)\\/(p = 0.032) respectively. Serum creatinine (p = 0.013) was similarly significantly associated with the presence of a complication. CONCLUSIONS: The E-PASS model possessing increasing external validity is an effective risk stratification tool in safely deciding the appropriate level of post-operative care for elective infrarenal AAA repairs.

    Objective: The arterial spasm which often seen in the coronary angiography was considered as a result of the pathological spasm of the coronary artery or a complication of catheterization. The coronary arterial spasm is a considerable situation because it increases the danger of stenotic lesions in coronary artery, which should be managed immediately. Methods: In total 37 patients presented with coronary arterial spasm in the coronary angiography (Judkins method): 23 male and 14 female, aged 43-60 years (the 47 years in average). Spasms were relieved in all patients after the administration of glonoin. Results: Solitary spasm were the most common, the angiographic findings were long section (>10 mm) with stenosis of 50%-65% in left anterior descending artery (12 cases), or in the middle and near portion of the right coronary artery (5 cases), where the orifice of the branches were involved; severe stenosis of the orifice of the right coronary artery (3 cases); irregular, mild and local spasm in left anterior descending artery or circumflex (8 cases). And multiple spasm was observed in left anterior descending artery (4 cases) or in the right coronary artery (5 cases). In 19 cases, stenosis accompanying with spasm were revealed and local spasm were observed at the site of arterial sclerosis. Conclusion: The spasm owing to the catheterization doesn't result in chest discomfort and changes in EKG, while pathological spasm occurs in the population with high risk of coronary heart disease, which indicates the potential myocardial infraction. The angiographic findings helps differentiating the two situation

    Clostridium difficile infection is caused by the proliferation of a gram-positive anaerobic bacteria after medical or surgical intervention and can result in toxic complications, emergent surgery, and death. This analysis evaluates the incidence of C difficile infection in elective restoration of intestinal continuity compared with elective colon resection. This was a retrospective database review of the 2015 American College of Surgeons National Surgical Quality Improvement Project and targeted colectomy database. The intervention cohort was defined as the primary Current Procedural Terminology codes for ileostomy/colostomy reversal (44227, 44620, 44625, and 44626) and International Classification of Diseases codes for ileostomy/colostomy status (VV44.2, VV44.3, VV55.2, VV55.3, Z93.2, Z93.3, Z43.3, and Z43.2). A total of 2235 patients underwent elective stoma reversal compared with 10403 patients who underwent elective colon resection. Multivariate regression modeling of the impact of stoma reversal on postoperative C difficile infection risk was used as the study intervention. The incidence of C difficile infection in the 30 days after surgery was measured. The incidence of C difficile infection in the 30-day postoperative period was significantly higher (3.04% vs 1.25%; p difficile infection incidence in the 30-day postoperative period. The study was limited because it was a retrospective database review with observational bias. Patients who undergo elective stoma reversal have a higher incidence of postoperative C difficile infection compared with patients who undergo an elective colectomy. Given the impact of postoperative C difficile infection, a heightened sense of suspicion should be given to symptomatic patients after stoma reversal.

    Full Text Available We describe the unexpected case of a 70-year-old man, with medical history of ischemic heart disease and surgery for aneurysm of abdominal aorta, who comes to the emergency department complaining of low-back pain without other symptoms or signs of organic failure. After a few hours we see a deterioration of physical conditions with pulmonary oedema, increase of blood pressure, changing in the ECG pattern, and worsening of left ventricular function with progressive increase of biomarkers for myocardial necrosis. So this pain has revealed the premature symptom of an acute coronary syndrome (ACS. After a short time a subsequent cardiac arrest complicates the clinical situation. After resuscitation, the patient undergoes successfully to coronary angiography and performed a percutaneous transluminal coronary angioplasty (PTCA.

    To assess the mortality in patients with diabetes mellitus (DM) following percutaneous coronary intervention (PCI) according to their insulin requirement and PCI setting (elective, urgent, and emergency). DM is a major risk factor to develop coronary artery disease (CAD). It is unclear if meticulous glycemic control and aggressive risk factor management in patients with DM has improved outcomes following PCI. Retrospective analysis of prospectively collected data on 9,224 patients treated with PCI at a regional tertiary center between 2008 and 2011. About 7,652 patients were nondiabetics (non-DM), 1,116 had non-insulin treated diabetes mellitus (NITDM) and 456 had ITDM. Multi-vessel coronary artery disease, renal impairment and non-coronary vascular disease were more prevalent in DM patients. Overall 30-day mortality rate was 2.4%. In a logistic regression model, the adjusted odds ratios (95% confidence intervals [CI]) for 30-day mortality were 1.28 (0.81-2.03, P = 0.34) in NITDM and 2.82 (1.61-4.94, P diabetes, this study reveals higher mortality only in insulin-treated diabetic patients following PCI for stable coronary artery disease and acute coronary syndrome. Importantly, diabetic patients with good risk factor control and managed on diet or oral hypoglycemics have similar outcomes to the non-diabetic population. © 2016 The Authors Catheterization and Cardiovascular Interventions Published by Wiley Periodicals, Inc. © 2016 The Authors Catheterization and Cardiovascular Interventions Published by Wiley Periodicals, Inc.

    1978-01-01

    Thallium-201 myocardial imaging can detect abnormalities of myocardial perfusion. Visual interpretation of the images is complicated by some inhomogeneity of tracer uptake normally present. Using a quantitative approach we have established the regional variation of Thallium-201 uptake present in 23 normal controls and applied the same technique to 49 patients who had undergone selective coronary arteriography with left ventriculography because of chest pain. Half of the patients with significant coronary artery disease had abnormal rest Thallium-201 images, usually corresponding to areas of abnormal wall motion at ventriculography. Stress Thallium-201 images were abnormal in over 90% of patients with coronary artery disease. The stress image abnormalities and the arteriographic lesions correlated well in most patients with single and double vessel disease but in triple vessel disease the correspondence between the two studies was poor. Two of a group of patients with normal coronary arteriograms had abnormal Thallium-201 images due to other myocardial pathology. Our technique was highly sensitive in the non-invasive detection of significant coronary artery disease in a group of patients with chest pain. A small number of positive studies were also encountered due to other myocardial disorders. (author)

    1991-09-01

    With use of a nonpharmacological, simple, and inexpensive program for blood conservation, 500 consecutive patients underwent elective coronary artery bypass grafting without need of homologous red cell transfusions in 493 (98.6%). At least one internal mammary artery was grafted in all but 1 patient, with supplemental saphenous vein grafts. Intraoperatively, autologous heparinized blood was removed before bypass and retransfused at the conclusion of extracorporeal circulation. The volume remaining in the oxygenator and tubing set was returned without cell processing or hemofiltration. Using the hard-shell cardiotomy reservoir from the heart-lung machine, autotransfusion of the shed mediastinal blood was continued hourly up to 18 hours after operation. The mean postoperative mediastinal blood loss was 643 +/- 354 mL, whereas 624 +/- 296 mL was autotransfused. Thirteen patients (2.6%) needed reexploration for bleeding, of whom 7 (7/500, 1.4%) received homologous blood. No other patients required red cell transfusions. In addition, 9 patients were given a mean of 2.6 units of fresh frozen plasma because of suspected coagulopathy. No platelets were transfused, and no cryoprecipitate therapy was undertaken. Thus, in total, 484 patients (96.8%) were not exposed to any homologous blood products during the hospital stay. At discharge, the mean hemoglobin concentration was 121 +/- 14 g/L (12.1 +/- 1.4 g/dL) and the hematocrit, 0.36 +/- 0.04. Postoperative complications were few. There was one in-hospital death (0.2%).

    Full Text Available Vacuum-assisted closure (VAC has recently been adopted as an acceptable modality for management of sternotomy wound infections. Although generally efficacious, the use of negative pressure devices has been associated with complications such as bleeding, retention of sponge, and empyema. We report the first case of greater omental hernia as a rare complication of vacuum-assisted closure of sternal wound infection following coronary artery bypass grafting.

    To investigate the lipid-regulating effect and safety of combined statin and bezafibrate therapy in acute coronary syndrome(ACS) patients complicating with dyslipedemia. One hundred and four hospitalized patients with established ACS and increased serum triglycerides (TG) levels and/or low serum levels of high density lipoprotein cholesterol (HDL-C) were selected. Except for conventional therapy, the patients were randomly divided into 2 groups: control group (n = 52), treated with atorvastatin 20 mg qn or other statin equivalent to 20 mg atorvastatin; treatment group (n = 52), treated with the same dose statin plus bezafibrate 200 mg bid. The serum levels of total cholesterol (TC), TG, low-density lipoprotein cholesterol (LDL-C) and HDL-C were assessed before and after 6 and 12 weeks treatment, side effects and adverse events were recorded. After 6 weeks treatment, the serum levels of TC, TG and LDL-C in two groups were significantly reduced compared to baseline (all P 0.05). After 12 weeks, the rates reaching to target goals of LDL-C, TG, HDL-C, and non-HDL-C levels in the treatment group (69.2%, 88.5%, 92.3%, 46.2% and 65.4%, respectively) were significantly higher than those in the control group (34.6%, 65.4%, 46.2%, 7.7% and 42.3%, respectively, all P < 0.05). No serious side effects were observed in the two groups during the treatment period. The combined statin and bezafibrate treatment is safe and could increase the ratios of reaching target lipid levels in ACS patients complicating with increased TG and (or) decreased HDL-C.

    The Mathematics of Elections and Voting  takes an in-depth look at the mathematics in the context of voting and electoral systems, with focus on simple ballots, complex elections, fairness, approval voting, ties, fair and unfair voting, and manipulation techniques. The exposition opens with a sketch of the mathematics behind the various methods used in conducting elections. The reader is lead to a comprehensive picture of the theoretical background of mathematics and elections through an analysis of Condorcet’s Principle and Arrow’s Theorem of conditions in electoral fairness. Further detailed discussion of various related topics include: methods of manipulating the outcome of an election, amendments, and voting on small committees. In recent years, electoral theory has been introduced into lower-level mathematics courses, as a way to illustrate the role of mathematics in our everyday life.  Few books have studied voting and elections from a more formal mathematical viewpoint.  This text wi...

    Full Text Available The patient is a 54-year old man with a previous history of cerebral aqueduct stenosis and hydrocephalus resulting in malignant hypertension who had surgery for permanent ventriculo-peritoneal shunt. At age 41, he had coronary artery bypass graft (CABG surgery with the right internal mammary artery anastomosed to the posterior descending artery and a saphenous vein graft to the first obtuse marginal branch. The patient was recently admitted with pneumonia that rapidly deteriorated and he went in respiratory failure requiring mechanical ventilation. A thoracic CT investigation showed massive bilateral pulmonary infiltrates, pulmonary artery embolism and a large vein graft aneurysm with a maximal diameter of 40 mm (Figure 1 A-B. The management course was complicated with prolonged respiratory failure, persistent infection, despite negative cultures and extended hospital stay. After 50 days of slow recovery the patient was discharged with a need for home oxygen therapy. Ten days later, he was re-admitted with chest pain requiring admission to the coronary care unit where severe pulmonary hypertension was diagnosed with Doppler echocardiography. Troponin-T was mildly elevated, 1,3 ug/L (ref <0,01, CRP was 50 mg/L and chest X-ray showed bilateral lung infiltrates and wide pulmonary vessels. At this point a systo-diastolic murmur was heard at the left lower sternal edge. With a view of potential coronary reintervention and to evaluate the pulmonary hypertension, a coronary angiogram and a pulmonary artery cathetherisation were performed. This showed a new stenosis in the left anterior descending coronary artery and the pulmonary catheterisation showed a “step-up” in oxygen saturation in the pulmonary artery, suggesting a left-to-right shunt. The vein graft aneurysm did not contribute to the coronary circulation. A cardiovascular magnetic resonance scan revealed a communication between the vein graft aneurysm and the left branch pulmonary artery

    To assess long-term prognosis after low-dose 64-slice coronary computed tomography angiography (CCTA) using prospective electrocardiogram-triggering. We included 434 consecutive patients with suspected or known coronary artery disease referred for low-dose CCTA. Patients were classified as normal, with non-obstructive or obstructive lesions, or previously revascularized. Coronary artery calcium score (CACS) was assessed in 223 patients. Follow-up was obtained regarding major adverse cardiac events (MACE): cardiac death, myocardial infarction and elective revascularization. We performed Kaplan-Meier analysis and Cox regressions. Mean effective radiation dose was 1.7 ± 0.6 mSv. At baseline, 38% of patients had normal arteries, 21% non-obstructive lesions, 32% obstructive stenosis and 8% were revascularized. Twenty-nine patients (7%) were lost to follow-up. After a median follow-up of 6.1 ± 0.6 years, MACE occurred in 0% of patients with normal arteries, 6% with non-obstructive lesions, 30% with obstructive stenosis and 39% of those revascularized. MACE occurrence increased with increasing CACS (P < 0.001), but 4% of patients with CACS = 0 experienced MACE. Multivariate Cox regression identified obstructive stenosis, lesion burden in CCTA and CACS as independent MACE predictors (P ≤ 0.001). Low-dose CCTA with prospective electrocardiogram-triggering has an excellent long-term prognostic performance with a warranty period >6 years for patients with normal coronary arteries. (orig.)

    Abdominal obesity is an important cardiovascular risk factor. Therefore, identifying the best method for measuring waist circumference (WC) is a priority. To evaluate the eight methods of measuring WC in patients with acute coronary syndrome (ACS) as a predictor of cardiovascular complications during hospitalization. Prospective study of patients with ACS. The measurement of WC was performed by eight known methods: midpoint between the last rib and the iliac crest (1), point of minimum circumference (2); immediately above the iliac crest (3), umbilicus (4), one inch above the umbilicus (5), one centimeter above the umbilicus (6), smallest rib and (7) the point of greatest circumference around the waist (8). Complications included: angina, arrhythmia, heart failure, cardiogenic shock, hypotension, pericarditis and death. Logistic regression tests were used for predictive factors. A total of 55 patients were evaluated. During the hospitalization period, which corresponded on average to seven days, 37 (67%) patients had complications, with the exception of death, which was not observed in any of the cases. Of these complications, the only one that was associated with WC was angina, and with every cm of WC increase, the risk for angina increased from 7.5 to 9.9%, depending on the measurement site. It is noteworthy the fact that there was no difference between the different methods of measuring WC as a predictor of angina. The eight methods of measuring WC are also predictors of recurrent angina after acute coronary syndromes.

    Full Text Available Abstract Background Coronary artery disease is the leading cause of death in industrialized countries and most patients with diabetes die from complications of atherosclerosis. The objective of this study was to determine the presence of diabetes mellitus and other conventional coronary heart disease risk factors (cigarette smoking, hypertension and hyperlipidemia in patients with acute coronary events in an Iranian population. Methods The study included 514 patients with unstable angina or myocardial infarction (MI out of 720 patients admitted to CCU ward of a general hospital from March 2003 to March 2005. History of diabetes, hypertension and cigarette smoking, demographic indices, coronary heart disease and diabetes mellitus treatment, myocardial enzymes, serum triglycerides (TG and cholesterol and fasting and non fasting blood glucose levels and HbA1C of diabetics were recorded of admission sheets. The data were structured to appropriate one way ANOVA, T tests, and chi square test with SPSS 13 product for windows. Results Out of all patients 35.8% were female, 30% were diabetics (Duration 13.4 ± 8.7 years, 42% were smoker and 91% were hypertensive. Twenty four percent had MI and 76% had unstable angina. MI was significantly higher in diabetic patients (36.4% vs. 19.2%, P Conclusion In this study 19 out of 20 patients with acute coronary event have at least one of conventional cardiac risk factors. Diabetes and hypertension are leading risk factors, which may directly or indirectly interfere and predict more serious complications of coronary heart disease.

    Reduction of cognitive function is a possible side effect after cardiac surgery using cardiopulmonary bypass. We investigated the cerebroprotective effect of piracetam on cognitive performance in patients undergoing coronary artery bypass surgery under cardiopulmonary bypass. Patients scheduled for elective, primary and isolated coronary bypass surgery were randomised either to piracetam or placebo group. The study was performed in a double blind fashion. Patients received either 12 g piracetam or placebo at the beginning of the operation. Six neuropsychological subtests from the Syndrom Kurz Test and the Alzheimer's Disease Assessment Scale were performed preoperatively and on the third postoperative day. To assess the overall cognitive function and the degree of cognitive decline across all tests after surgery we combined the six test-scores by principal component analysis. A total number of 120 patients were enrolled into the study. Preoperative overall cognitive function were not significantly different between the groups. The postoperative combined score of the neuropsychological tests showed a deterioration of cognitive function in both groups (placebo-pre: -0.06+/-0.99 vs placebo-post: -1.38+/-1.11; ppiracetam-pre: 0.06+/-1.02 vs piracetam-post: -0.65+/-0.93; ppiracetam patients performed significantly better compared to the placebo patients after the operation and had a less decline of overall cognitive function (pPiracetam has a cerebroprotective effect in patients undergoing coronary artery bypass surgery with the use of cardiopulmonary bypass.

    To assess the diagnostic performance of angiography-derived fractional flow reserve (FFRangio) measurements in patients with stable coronary artery disease when used online in the catheterization laboratory during routine coronary angiography. FFR, an index of the hemodynamic severity of coronary stenosis, is derived from invasive measurements using a pressure-monitoring guidewire and hyperemic stimulus. While FFR is the gold standard, it remains under-utilized. FFRangio may have several advantages owing to the reduced operator time, no wire-related or procedural complications, and no need for administration of vasodilators. FFRangio is a novel technology that uses a patient's hemodynamic data and routine angiograms to generate FFR values at each point along the coronary tree. We present the online application of the system where FFRangio was successfully used in the catheterization laboratory during routine coronary angiography and compared to invasive FFR. Fifty-three patients (79% men) and 60 coronary lesions were analyzed. Values derived using FFRangio ranged from 0.58-0.96 and correlated closely (Pearson's correlation coefficient, r=0.91; Psystem. In this single-center experience, FFRangio values showed high correlation rates to invasive FFR.

    According to recent studies, multidetector-row CT (MDCT) with a retrospective electrocardiogram (ECG)-gating reconstruction algorithm shows a high correlation with coronary artery calcium score determined using electron-beam CT. Diabetes leads to many macrovascular complications, including coronary artery disease. The aim of this study was to evaluate risk factors for cardiac macroangiopathy in type 2 diabetes using MDCT. An observational cross-sectional study was performed in 90 patients with diabetes mellitus. Coronary calcium data was acquired by MDCT (SOMATOM Volume Zoom, Siemens AG, Medical Solutions, Germany). Physical examinations, laboratory data, glycemic control, and control of other risk factors were analyzed. The coronary artery calcium score increased with age. Multivariant analysis revealed that the coronary calcium score was closely correlated with electrocardiogram evaluation and control of hypertension. Coronary artery calcium score as determined by MDCT can be used as a screening radiological examination for cardiac macroangiopathy in diabetes patients with electrocardiogram abnormality and hypertension.

    Full Text Available Background: Gender differences among patients with the acute coronary syndrome is still being debated, no research has been done on gender inequality among coronary syndrome patients in Sudan. Objectives: To study gender differences in presentation, management, and outcomes of acute coronary syndrome in Sudan. Subjects and Methods: This cross-sectional descriptive longitudinal study was conducted in Omdurman Teaching Hospital between July 2014 and August 2015. Patients were invited to sign a written informed consent form, were interviewed and examined by a physician, and then followed during their hospital stay. Information collected includes coronary risk factors, vital signs, echocardiography findings, arrhythmias, heart failure, cardiogenic shock, and death. The Ethical Committee of Omdurman Teaching Hospital approved the research. Results: A total of 197 consecutive acute coronary syndrome patients were included, 43.1% were females. A significant statistical difference was evident between males and females regarding the type of acute coronary syndrome, its presentation, and time of presentation to the hospital, smoking, and receipt of thrombolysis (P 0.05. Conclusion: Women were less likely to receive thrombolytic therapy, present with chest pain, and diagnosed with ST-segment elevation myocardial infarction. No gender differences were found in acute coronary syndrome risk factors apart from smoking, which was more common in males, and there were no differences between males and females as regards in-hospital complications.

  7. Bioabsorbable coronary stents--are these the next big thing in coronary angioplasty?

    2010-06-01

    The role of percutaneous coronary intervention (PCI) in the treatment of coronary artery disease has grown at an astronomical pace. Drug eluting stents (DES) offer advantages over bare metal stents (BMS) such as reduction in early in-stent restenosis rates. However, they have disadvantages like from increased late stent thrombosis when compared with BMS. Furthermore, recent data suggest endothelial dysfunction in the DES stented segments of the arteries. Currently, bioabsorbable stents are under development to avert the complications of DES such as stent thrombosis via degradation of the stent over time. The hypothetical advantage of leaving behind a natural vessel and restoring vasoreactivity may be the almost normal physiology which can be achieved after an intervention with a stent. The ABSORB and the PROGRESS AMS are two of the recent clinical trials that have looked at the outcomes of using bioabsorbable stents. So far, data from these and other studies has yielded mixed results in terms of angiographic and clinical outcomes. Newer stents such as REVA and WHISPER are presently being tested in preclinical and clinical trials. The landscape for bioabsorbable stents is constantly evolving through continued improvisation on existing technology and emergence of new technology. Large scale randomized trials are still needed with adequate long term follow-up for safety and benefits to have mainstream application in coronary artery disease, bioabsorbable stents are a promising innovation in the field of PCI. We review some of the patents and the data that is emerging on bioabsorbable stents in addition to currently ongoing clinical trials.

    Full Text Available Background: Extraction in orthodontics are carried out in the cases where there is space deficiency to align the teeth. The elective extraction of first or second premolars has been discussed in the literature for more than 50 years. In the 1940s and 1950s Nance, Dewel and Carey reviewed this as a useful option, and in the 1970s Logan and other leading orthodontists favoured the extraction as choice. It is not always the elective extraction of premolar is a smooth drive for the surgeon as well as to patient. Sometimes the elective extraction of premolar result in complications, which might be due to both anatomical and surgical factors. Methodology: The study sample consisted of 100 patients referred for one or more orthodontic extractions to the department of oral and maxillofacial surgery were included in this retrospective study at the vivekanandha dental college for women tiruchengode between November 2014 and May 2016. All referrals were from the department of orthodontics. A survey was carried out to record the intraoperative risks and correlated with its morbidity as when occured. All intraoperative morbities were managed appropriately as required. Result and Conclusion: Between November 2014 and May 2016, 100 patients had one or more premolar teeth removed by the oral surgeons. The sample size was 100 patients who had a total of 334 premolars removed. The sample's mean age was 11.4+\\- 8.4 years, and 57.0% were male.

    Purpose: To assess the variation in and the three-dimensional dosimetric consequences of treatment portals for elective neck irradiation. Materials and methods: Radiation oncologists (n = 16) from all major Head and Neck Co-operative Groups in The Netherlands (n = 11) were asked to delineate treatment portals on a lateral and an anterior simulation film in case of elective neck irradiation for a T3N0 tumour of the supraglottic larynx and a T2N0 tumour of the mobile tongue. In addition, they had to define their target, i.e. which parts of the neck nodal regions they would choose to irradiate electively for these particular tumour sites. Subsequently, treatment portals were compared and evaluated using CT-data and a 3-dimensional (3D) treatment planning system. Results: Significant variations were found in the shapes and sizes of the applied treatment techniques and portals. Also, among radiation oncologists who elected to irradiate the same lymph node regions, a significant variation in the delineated treatment portals was observed. As a consequence, substantial variations in treated volumes and in calculated normal tissue complication probabilities (NTCPs) for the parotid- and submandibular glands were observed. Conclusion: For the tumour sites studied there appears to be a lack of standardisation in the areas of the neck to be irradiated electively. The observed differences may have consequences for the ultimate failure rate and particularly with regard to the side effects, e.g. the degree of xerostomia. It is argued that in the near future a more precise three-dimensional definition on CT of the lymph node regions in the neck might allow for a better standardisation of the treatment portals and, in addition, for the development and application of conformal radiotherapy techniques for optimal sparing of the critical normal tissues (e.g. parotid- and submandibular glands) with maximum tumour control probability

    Navigator echo-based respiratory-gated three dimensional coronary magnetic resonance angiography (3D-CMRA) was compared with echocardiography, to determine whether 3D-CMRA was useful for the evaluation of Kawasaki disease-associated coronary artery lesions. Sixteen consecutive patients (imaging was performed 17 times in total) who were given a diagnosis of Kawasaki's disease at the pediatric department of our hospital and examined for the precise examination of complicating coronary artery lesions on MRI using a navigator-echo technique because of their incapability of holding their breath during imaging were entered into the present study. A 1.5T MRI system was used. Gd-DOTA was given at a total volume of 0.1 mmol/kg. During imaging, CMRA visualized the left coronary arteries in all 17 cases and the right coronary arteries in 16 cases, but not in one case. The left main coronary trunk segment no.5 was demonstrated in all cases with CMRA, but not in 4 cases with echocardiography. The left anterior descending branch no.6 was visualized in 11 of the 17 cases with CMRA, but only in 5 cases with echocardiography. The left circumflex branch no.11 was observed in 6 cases with CMRA, but only in 2 cases with echocardiography. As for the right coronary arteries, branches no.1 and no.2 were observed in 16 and 9 cases with CMRA, respectively, and in 13 and 3 cases with echocardiography, respectively. Vascular diameters measured on CMRA were almost identical to those on echocardiography, within the range of arteries visualized. 3D-CMRA combined with a navigator echo technique appears to be a useful tool for the observation of coronary artery lesions associated with Kawasaki's disease because it is superior in lesion visualization to echocardiography.

    Full Text Available OBJECTIVE: To assess the in-hospital results and clinical follow-up of young patients (< 50 years with multivessel coronary artery disease undergoing stent implantation in native coronary arteries and to compare their results with those of patients with single-vessel coronary artery disease. METHODS: We retrospectively studied 462 patients undergoing coronary stent implantation. Patients were divided into 2 groups: group I (G-I - 388 (84% patients with single-vessel coronary artery disease; and group II (G-II - 74 (16% patients with multivessel coronary artery disease. RESULTS: The mean age of the patients was 45±4.9 years, and the clinical findings at presentation and demographic data were similar in both groups. The rate of clinical success was 95% in G-I and 95.8% in G-II (P=0.96, with no difference in regard to in-hospital evolution between the groups. Death, acute myocardial infarction, and the need for myocardial revascularization during clinical follow-up occurred in 10.1% and 11.2% (P=0.92 in G-I and G-II, respectively. By the end of 24 months, the actuarial analysis showed an event-free survival of 84.6 % in G-I and 81.1% in G-II (P=0.57. CONCLUSION: Percutaneous treatment with coronary stent implantation in young patients with multivessel disease may be safe with a high rate of clinical success, a low incidence of in-hospital complications, and a favorable evolution in clinical follow-up.

    Full Text Available Persons with aneurysm of the abdominal aorta have high prevalence of risk factors of cardiovascular disease. It cannot be stated with certainty whether these persons die in a large number due to the existence of risk factors or the genesis and complications of aneurysm itself. In patients with aneurysm of the abdominal aorta, there is a high correlation with the coronary artery disease; therefore, the aim of the study was to prove whether or not this is the case. The patients in preparation for the resection of the abdominal aorta aneurysm at the Institute of Cardiovascular Disease underwent the examination. The study included 377 examinees, of whom 341 males and 36 females, aged 45 to 83 years, during the three-year interval (from 2004 to 2006. The aim of the study was to determine the dominance of the coronary artery disease among the patients with aneurysm of the abdominal aorta. In the process of analyzing the data obtained from patients and medical evidence, it was found out that a large number of the abdominal aortic aneurysm patients were at the same time the coronary artery disease patients (55,2%; Hi=15,04; p80 kg was larger, as well as the percentage of patients with hypertension (89% and increased levels of cholesterol and triglycerides (67%. There was a great number of those with the inherited factor (40%. It has been proven that the risk factors for the development of coronary artery disease are in direct association with the risk factors for the abdominal aortic aneurysm. Also, there is a great predominance of the coronary artery disease among the patients with aneurysm of the abdominal aorta. The coronary artery disease is one of the main risk factors. If we managed to prevent the appearance of this disease or achieve the timely diagnosing of it and eventual curing, we would be able to decrease the development of the abdominal aortic aneurysm well as the consequences and further complications.

  15. Electing Not to Fight: Elections as a Mechanism of Deradicalisation after the Irish Civil War 1922–1938

    2012-05-01

    Full Text Available Much research into the relationship between democratisation and conflict argues that holding elections soon after civil war, when nationalist issues still resonate, is likely to see voters elect to fight. This paper explores a case where elections had the opposite effect. Examination of the relationship between election results and political developments, as well as geographical voting patterns, demonstrates that elections were the primary mechanism for the deradicalisation of Irish politics after the civil war of 1922–23. Elections served as a mechanism for arbitration, selection, and coordination between more and less radical elites and their bases of support. Once the new state had shown its strength it had to accommodate gradual change, while electoral losers had to show they could reconcile change with stability. Elections helped establish credibility in both respects without altering the state-society relationship, suggesting that deradicalisation was dependent on state performance, and thus on some shared conception of the state. This combination of credibility, electoral legitimacy, and state performance, enabled a revolutionary elite, schooled in both constitutional and revolutionary politics, to deradicalise Irish nationalism after independence.

    2008-04-01

    Full Text Available Abstract Background Plasma concentrations of sFlt-1, the soluble form of the vascular endothelial growth factor receptor (VEGF, markedly increase during coronary artery bypass graft (CABG surgery with extracorporeal circulation (ECC. We investigated if plasma sFlt-1 values might be related to the occurrence of surgical complications after CABG. Methods Plasma samples were collected from the radial artery catheter before vascular cannulation and after opening the chest, at the end of ECC just before clamp release, after cross release, after weaning from ECC, at the 6th and 24th post-operative hour. Thirty one patients were investigated. The presence of cardiovascular, haematological and respiratory dysfunctions was prospectively assessed. Plasma sFlt-1 levels were measured with commercially ELISA kits. Results Among the 31 investigated patients, 15 had uneventful surgery. Patients with and without complications had similar pre-operative plasma sFlt-1 levels. Lowered plasma sFlt-1 levels were observed at the end of ECC in patients with haematological (p = 0.001, ANOVA or cardiovascular (p = 0.006 impairments, but not with respiratory ones (p = 0.053, as compared to patients with uneventful surgery. Conclusion These results identify an association between specific post-CABG complication and the lower release of sFlt-1 during ECC. sFlt-1-induced VEGF neutralisation might, thus, be beneficial to reduce the development of post-operative adverse effects after CABG.

    2005-09-01

    Full Text Available Abstract Background Stress echocardiography is a cost-effective tool for the modern noninvasive diagnosis of coronary artery disease. Several physical and pharmacological stresses are used in combination with echocardiographic imaging, usually exercise, dobutamine and dipyridamole. The safety of a stress is (or should be a major determinant in the choice of testing. Although large scale single center experiences and multicenter trial information are available for both dobutamine and dipyridamole stress echo testing, complications or side effects still can occur even in the most experienced laboratories with the most skilled operators. Case presentation We decided to present a case collection of severe complications during pharmacological stress echo testing, including a ventricular tachycardia, cardiogenic shock, transient ischemic attack, torsade de pointe, fatal ventricular fibrillation, and free wall rupture. Conclusion We believe that, in this field, every past complication described is a future complication avoided; what happens in your lab is more true of what you read in journals; and Good Clinical Practice is not "not having complications", but to describe the complications you had.

    2005-10-01

    To investigate the influence of cardiopulmonary bypass on pulmonary hemodynamics and gas exchange. Low risk patients admitted for elective coronary artery bypass grafting were randomized to either on (n=25) or off pump (n=25) surgery. Central hemodynamics, gas exchange, and venous admixture were studied during and up to 20 h after surgery. There was no difference in pulmonary vascular resistance index (P=0.16), right ventricular stroke work index (P>0.2), mean pulmonary artery pressure (P>0.2) or pulmonary capillary wedge pressure (P>0.2) between groups. Soon after surgery there was a tendency towards higher cardiac index (P=0.07) in the off pump group. Arterial oxygen tension (P>0.2), hematocrit (P>0.2), venous admixture (P>0.2), and arterial-venous oxygen content difference (P=0.12) did not differ between groups. This prospective, randomized study showed no difference in pulmonary hemodynamics, pulmonary gas exchange, and venous admixture, in low risk patients undergoing off pump compared to on pump coronary artery bypass surgery.

    Ionizing radiation is an integral part of percutaneous coronary angiographies. Chronic exposure to low-dose radiation confers a risk for skin damage, eye lens opacities or cataracts, and malignant diseases to staff in the catheter laboratory. The RADPAD is a sterile surgical drape that reduces the effect of scatter radiation on the operator. We sought to assess the efficacy of RADPAD shields in reducing radiation dose experienced by operators during routine diagnostic coronary angiography. Sixty consecutive patients due to undergo elective coronary angiography were randomized in a 1:1 pattern to have their procedures performed with and without the RADPAD drape in situ. Dosimetry was performed on the left arm of the primary operator. There was no significant difference in the two main determents of radiation exposure in both groups: the screening times (102 ± 86 s for the RADPAD group vs. 105 ± 36 s for the control group, p = 0.9) and body mass index (BMI; 27.7 ± 4.2 kg/m 2 for the RADPAD group vs. 27.9 ± 5.5 kg/m 2 for the control group, p = 0.8). Moreover, there was no difference in the dose-area ratio (1337 ± 582 cGy/cm 2 for the RADPAD group vs. 1541 ± 804 cGy/cm 2 for the control group, p = 0.3) between the two patient groups. The primary operator radiation dose was significantly lower in the RADPAD group at 8.0 µSv (Q1: 3.2, Q3: 20.1) compared with 19.6 µSv (Q1: 7.1, Q3: 37.7) for the control group (p = 0.02). The RADPAD significantly reduces radiation exposure to primary operators during routine diagnostic coronary angiography in patients with a BMI > 25 kg/m 2 . It reduces total radiation exposure to primary operators by 59%, and the radiation exposure rate by 47%.

    Coronary artery bifurcation disease of saphenous venous graft (SVG) is extremely rare. SVG disease remains a challenging lesion to treat because of increased morbidity and mortality with repeated coronary artery bypass graft surgery (CABG), high rates of periprocedural complications, and in-stent restenosis or occlusion requiring repeat revascularization with percutaneous coronary intervention. Herein, we present the first reported case of using the "DK crush" technique to treat an inverted Y-shaped SVG bifurcation disease in a patient with a prior CABG and new-onset acute coronary syndrome. Arising from our treatment, favorable immediate and mid-term angiographic and clinical outcomes were obtained.

    The variation in treatment portals for elective radiotherapy of the neck, and the three-dimensional dosimetric consequences of this variation was assessed. Therefore, 16 experienced radiation oncologists from all major head and neck cooperative groups in the Netherlands (n=11) were asked to define RT-portals on a lateral and/or AP simulation film, for (routine) elective neck irradiation for a T2 tumor of the mobile tongue and a T3 tumor of the supraglottic larynx. Treatment portals were compared and evaluated using a three-dimensional treatment planning system and CT data with contoured critical structures and target volume. The CT-defined clinical target volume was mutually agreed upon by ENT-surgeons and radiation oncologists. Large differences were seen in treated volume (a factor of five). In addition, due to the variation in the cranial boundary of the RT-portals, the estimated NTCP varied considerably (0-50%). Moreover, several of the RT-portals did not adequately cover the CT-defined target volume. Even amongst experienced head and neck radiation oncologists, little agreement was observed with respect to treatment technique and size of the treatment portals in case of elective neck irradiation. This results in a considerable variation in treated volume. As a consequence, a large difference exists in the anticipated probability of normal tissue complication, and possibly in tumor control probability. Therefore, a definition of target volume and, consequently, a standardization of elective neck portals in mandatory. This is even more important if the primary tumor and clinically node-negative neck are to be treated by 3D conformal RT using multiple CT-slices for target delineation and positioning of BEV blocks in order to spare the normal tissue function with maximum tumor control probability.

    2017-01-01

    Full Text Available Introduction: While off pump coronary artery bypass surgery is practiced with an intention to reduce the morbidity associated with cardiopulmonary bypass, the resultant ′hypercoagulability′ needs to be addressed. Complications such as cavitary thrombus possibly due to the hyper coagulability after off pump coronary artery bypass surgery have been described. Many clinicians use higher doses of heparin - up to 5 mg/kg in order to thwart this fear. Overall, there appears to be no consensus on the dose of heparin in off pump coronary artery bypass surgeries. Aim of the Study: The aim of the study was understand the differences in outcome of such as transfusion requirement, myocardial ischemia, and morbidity when two different doses were used for systemic heparinization. Methods: Elective patients scheduled for off pump coronary artery bypass surgery were included. Ongoing anti platelet medication was not an exclusion criteria, however, anti platelet medications were ceased about a week prior to surgery when possible. Thoracic epidural anesthesia was administered as an adjunct in patients who qualified for it. By computer generated randomization chart, patients were chosen to receive either 2 or 3 mg/kg of intravenous unfractioned heparin to achieve systemic heparinization with activated clotting time targeted at >240 secs. Intraoperative blood loss, postoperative blood loss, myocardial ischemic episodes, requirement of intraaortic balloon counter pulsation and transfusion requirement were analyzed. Results: Sixty two patients participated in the study. There was one conversion to cardiopulmonary bypass. The groups had comparable ACT at baseline (138.8 vs. 146.64 seconds, P = 0.12; 3 mg/kg group had significantly higher values after heparin, as expected. But after reversal with protamine, ACT and need for additional protamine was similar among the groups. Intraoperative (685.56 ± 241.42 ml vs. 675.15 ± 251.86 ml, P = 0.82 and postoperative

    Full Text Available Introduction: It has been argued in current studies that anabolic androgenic steroids (AAS are misused by a great number of bodybuilders and athletes. However, there is diverse and often conflicting scientific data on the cardiac and metabolic complications caused by the misuse of AAS. There may be various reasons for myocardial infarction (MI with normal coronary arteries. However, for the majority of patients, the exact cause is still unknown. Case report: A 32 year-old male who was complaining about severe chest pain was admitted to our emergency department. He had been taking methenolone acetate 200 mg weekly for a period of three years for body building. His cardiac markers were significantly elevated and electrocardiogram (ECG showed peaked T waves in all derivations, which did not show ST elevation or depression. Both right and left coronary artery systems were found to be completely normal as a result of the angiogram. Conclusion: The purpose of this study is to show that AAS induced MI can be encountered with normal coronary arteries during acute coronary syndrome.

    Cosmetic procedures are common and utilize many techniques to obtain aesthetically good outcomes for patient satisfaction with acceptable safety standards. Cosmetic procedures that involve the gluteal region are becoming increasingly popular as various procedures can target the gluteal region such as liposuction, tumescent liposuction, cosmetic filler injections, autologous fat transfer, depot drug delivery, and implants. Complications of cosmetic gluteal procedures can be localized or systemic with systemic complications being responsible for most deaths. These reported systemic complications include sepsis, thromboembolism, fat embolism with or without fat embolism syndrome, macroscopic fat embolism, anesthesia-related and blood volume abnormalities. We herein report 10 deaths due to elective gluteal cosmetic procedures. Autologous fat transfer (fat grafting, lipoinjection) following liposuction resulted in 8 of 10 fatal outcomes of the gluteal aesthetic procedures. A comprehensive discussion of gluteal anatomy, gluteal contouring procedures, and the approach to such cases is presented along with the autopsy findings of the reported cases. © 2018 American Academy of Forensic Sciences.

    Objective: To evaluate the safety and efficacy of domestic biodegradable drug-eluting stent, EXCEL, in clinical treatment of coronary heart disease. Methods: During the period of Jan. 2008-Oct. 2008, 100 patients with coronary heart disease who consented to PCI and postoperative coronary angiography were selected and enrolled in the study. The patients were divided into EXCEL group (n = 58) and Cypher group (n = 42). The immediate successful rate of interventional therapy and the complications occurred during hospitalization were observed. Postoperative follow-up and checkup coronary angiography were conducted. Results: No significant difference in the relevant clinical data, in the number and type of diseased coronary branch and in the mean length of implanted stents existed between two groups. Also, no statistically significant difference in the occurrence of major adverse cardiac event (MACE), in-stent restenosis and thrombosis was present between two groups. Conclusion: Compared with Cypher stenting, EXCEL stenting carries similar, i.e. rather low, occurrence of MACE and in-stent restenosis. (authors)

Instead of flat out rejecting the technology as uncontrollably dangerous, we advocate in this paper a different technological angle that renders electronic elections trustworthy beyond...... the usual levels of doubt. We exploit the trust that voters currently have into the democratic process and model our techniques around that observation accordingly. In particular, we propose a technique of trace emitting computations to record the individual steps of an electronic voting machine...... for a posteriori validation on an acceptably small trusted computing base. Our technology enables us to prove that an electronic elections preserves the voter’s intent, assuming that the voting machine and the trace verifier are independent....

  14. Clinical Implications of Glucose Variability: Chronic Complications of Diabetes

    Full Text Available Glucose variability has been identified as a potential risk factor for diabetic complications; oxidative stress is widely regarded as the mechanism by which glycemic variability induces diabetic complications. However, there remains no generally accepted gold standard for assessing glucose variability. Representative indices for measuring intraday variability include calculation of the standard deviation along with the mean amplitude of glycemic excursions (MAGE. MAGE is used to measure major intraday excursions and is easily measured using continuous glucose monitoring systems. Despite a lack of randomized controlled trials, recent clinical data suggest that long-term glycemic variability, as determined by variability in hemoglobin A1c, may contribute to the development of microvascular complications. Intraday glycemic variability is also suggested to accelerate coronary artery disease in high-risk patients.

    The large conductance Ca(2+)-activated K(+) (BK) channels, abundantly expressed in coronary artery smooth muscle cells (SMCs), play a pivotal role in regulating coronary circulation. A large body of evidence indicates that coronary arterial BK channel function is diminished in both type 1 and type 2 diabetes. However, the consequence of coronary BK channel dysfunction in diabetes is not clear. We hypothesized that impaired coronary BK channel function exacerbates myocardial ischemia/reperfusion (I/R) injury in streptozotocin-induced diabetic mice. Combining patch-clamp techniques and cellular biological approaches, we found that diabetes facilitated the colocalization of angiotensin II (Ang II) type 1 receptors and BK channel α-subunits (BK-α), but not BK channel β1-subunits (BK-β1), in the caveolae of coronary SMCs. This caveolar compartmentation in vascular SMCs not only enhanced Ang II-mediated inhibition of BK-α but also produced a physical disassociation between BK-α and BK-β1, leading to increased infarct size in diabetic hearts. Most importantly, genetic ablation of caveolae integrity or pharmacological activation of coronary BK channels protected the cardiac function of diabetic mice from experimental I/R injury in both in vivo and ex vivo preparations. Our results demonstrate a vascular ionic mechanism underlying the poor outcome of myocardial injury in diabetes. Hence, activation of coronary BK channels may serve as a therapeutic target for cardiovascular complications of diabetes.

    Indications for removing orthopedic hardware on an elective basis varies widely. Although viewed as a relatively benign procedure, there is a lack of data regarding overall complication rates after fracture fixation. The purpose of this study is to determine the overall short-term complication rate for elective removal of orthopedic hardware after fracture fixation and to identify associated risk factors. Adult patients indicated for elective hardware removal after fracture fixation between July 2012 and July 2016 were screened for inclusion. Inclusion criteria included patients with hardware related pain and/or impaired cosmesis with complete medical and radiographic records and at least 3-month follow-up. Exclusion criteria were those patients indicated for hardware removal for a diagnosis of malunion, non-union, and/or infection. Data collected included patient age, gender, anatomic location of hardware removed, body mass index, ASA score, and comorbidities. Overall complications, as well as complications requiring revision surgery were recorded. Statistical analysis was performed with SPSS 20.0, and included univariate and multivariate regression analysis. 391 patients (418 procedures) were included for analysis. Overall complication rates were 8.4%, with a 3.6% revision surgery rate. Univariate regression analysis revealed that patients who had liver disease were at significant risk for complication (p=0.001) and revision surgery (p=0.036). Multivariate regression analysis showed that: 1) patients who had liver disease were at significant risk of overall complication (p=0.001) and revision surgery (p=0.039); 2) Removal of hardware following fixation for a pilon had significantly increased risk for complication (p=0.012), but not revision surgery (p=0.43); and 3) Removal of hardware for pelvic fixation had a significantly increased risk for revision surgery (p=0.017). Removal of hardware following fracture fixation is not a risk-free procedure. Patients with

    Our aim was to examine hospital outcomes of coronary artery bypass surgery in patients with and without left ventricular dysfunction, with regard to the surgical technique (off- or on-pump). Between March 2007 and March 2008, 689 consecutive patients underwent isolated first-time coronary artery bypass; 127 had ejection fractions fractions >30% (group 2). Data of preoperative risk profiles and hospital outcomes were collected prospectively. Off-pump operations were performed in 49 (38.6%) patients in group 1 and 196 (34.9%) in group 2. The incidences of infectious, neurologic, and cardiac complications postoperatively were significantly higher in group 1. In multivariate analysis, preoperative ejection fraction operations, but no significant difference in mortality was observed between those undergoing off-pump or conventional surgery in either group. Off-pump surgery helped to limit the increased morbidity rate after coronary bypass in patients with ventricular dysfunction.

  1. Modern antiplatelet agents in coronary artery disease.

    LENUS (Irish Health Repository)

    Power, Rachel F

    2012-10-01

    Dual antiplatelet therapy is well recognized in the prevention of thrombotic complications of acute coronary syndrome and percutaneous coronary interventions. Despite clinical benefits of aspirin and clopidogrel therapy, a number of limitations curtail their efficacy: slow onset of action, variability in platelet inhibitory response and potential drug-drug interactions. Furthermore, the single platelet-activation pathway targeted by these agents allows continued platelet activation via other pathways, ensuring incomplete protection against ischemic events, thus, underscoring the need for alternate antiplatelet treatment strategies. A number of novel antiplatelet agents are currently in advance development and many have established superior effects on platelet inhibition, clinical outcomes and safety profile than clopidogrel in high-risk patients. The aim of this review is to provide an overview of the current status of P2Y12 receptor inhibition and PAR-1 antagonists in determining a future strategy for individualized antiplatelet therapy.

  2. Anesthesia for off-pump coronary artery bypass surgery

    Thomas M Hemmerling

    2013-01-01

    Full Text Available The evolution of techniques and knowledge of beating heart surgery has led anesthesia toward the development of new procedures and innovations to promote patient safety and ensure high standards of care. Off-pump coronary artery bypass (OPCAB surgery has shown to have some advantages compared to on-pump cardiac surgery, particularly the reduction of postoperative complications including systemic inflammation, myocardial injury, and cerebral injury. Minimally invasive surgery for single vessel OPCAB through a limited thoracotomy incision can offer the advantage of further reduction of complications. The anesthesiologist has to deal with different issues, including hemodynamic instability and myocardial ischemia during aorto-coronary bypass grafting. The anesthesiologist and surgeon should collaborate and plan the best perioperative strategy to provide optimal care and ensure a rapid and complete recovery. The use of high thoracic epidural analgesia and fast-track anesthesia offers particular benefits in beating heart surgery. The excellent analgesia, the ability to reduce myocardial oxygen consumption, and the good hemodynamic stability make high thoracic epidural analgesia an interesting technique. New scenarios are entering in cardiac anesthesia: ultra-fast-track anesthesia with extubation in the operating room and awake surgery tend to be less invasive, but can only be performed on selected patients.

    To describe the clinical and procedural coronary chronic total occlusion (CTO) treatment results in a Nordic PCI centre during the implementation of a CTO treatment program. In a retrospective registry study, we assessed; (1) indication for the procedure, (2) Canadian Cardiovascular Society angina pectoris score (CCS)/New York Heart Association (NYHA) heart failure score, (3) lesion complexity and (4) adverse events during hospital stay and three months following the index procedure. The study cohort included 503 patients (594 lesions). From 2010 to 2013 96% of procedures were performed with antegrade wire-escalation technique and 4% performed using retrograde techniques, from 2013-2016 the corresponding numbers were 83% and 17.0%. The procedural success rate was 69%, increasing from 64% before to 72% (p = .06) after routinely using the retrograde approach. No individual patient characteristic, lesion variable or score was strongly associated with procedural success or failure. There were 4% serious procedure related complications. In patients with PCI of a CTO lesion only, 87% were in CCS or NYHA functional class ≥2 before the index procedure vs. 22% at follow-up. Routine use of retrograde techniques tended to increase the procedural success rate. Clinical results after three months were acceptable, but the complication rate was higher than for non-CTO PCI. Individual patient and lesion characteristics had a low predictability for procedural success. Therefore, clinical symptoms, objective signs of myocardial ischemia and procedural risk should be focus points in coronary chronic total occlusion treatment strategies.

    Full Text Available BACKGROUND There is a paucity of data among octogenarians undergoing coronary interventions in India. These patients have generally been excluded from randomised trials. As a result, there are no evidence-based guidelines regarding PCI in very elderly. The aim of this study is to describe the epidemiology, clinical characteristics, management and the outcomes of patients over the age of 80 years who were undergoing coronary interventions. MATERIALS AND METHODS We evaluated the outcomes of all patients over the age of 80 years admitted in KIMS, Hubli, during the year 2015-16 undergoing coronary interventions including coronary angiography and Percutaneous Coronary Interventions (PCI. RESULTS We identified 36 octogenarians (67% men, 33% women; Mean Age of 84.2 ± SD 3.6 years. 52.3 percent of patients presented with an acute coronary syndrome treated either with thrombolysis or medical stabilisation followed by coronary angiography. One patient in the study was taken for primary Percutaneous Coronary Interventions (PCI. Mean duration of hospitalisation was 6.69 ± 6.8 days. Overall, the frequency of in-hospital death was n=2 (5.5% and both the patients died while awaiting CABG. CONCLUSION Our study shows that coronary interventions are safe and effective and are not associated with any major complications, which are specific to this subset. Thus, advanced age should not be considered a contraindication for coronary interventions when clear indications are present.

    Intravascular imaging modalities, such as Optical Coherence Tomography (OCT) allow nowadays improving diagnosis, treatment, follow-up, and even prevention of coronary artery disease in the adult. OCT has been recently used in children following Kawasaki disease (KD), the most prevalent acquired coronary artery disease during childhood with devastating complications. The assessment of coronary artery layers with OCT and early detection of coronary sequelae secondary to KD is a promising tool for preventing myocardial infarction in this population. More importantly, OCT is promising for tissue quantification of the inner vessel wall, including neo intima luminal myofibroblast proliferation, calcification, and fibrous scar deposits. The goal of this study is to classify the coronary artery layers of OCT imaging obtained from a series of KD patients. Our approach is focused on developing a robust Random Forest classifier built on the idea of randomly selecting a subset of features at each node and based on second- and higher-order statistical texture analysis which estimates the gray-level spatial distribution of images by specifying the local features of each pixel and extracting the statistics from their distribution. The average classification accuracy for intima and media are 76.36% and 73.72% respectively. Random forest classifier with texture analysis promises for classification of coronary artery tissue.

    2016-01-01

    Coronary artery perforation is a highly feared complication of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) and can lead to pericardial effusion, tamponade, and, rarely, emergent cardiac surgery. Perforation of epicardial collaterals during retrograde CTO-PCI may be particularly challenging to treat, as embolization from both sides of the perforation may be required to control the bleeding. However, conservative measures can occasionally be effective. We present a case of epicardial collateral vessel perforation that was managed conservatively with anticoagulation reversal.

    Objective: To investigate the relationship between angiotensin-converting enzyme gene polymorphism and cardio-brain complications in patients with NIDDM. Methods: The angiotensin-converting enzyme (ACE) gene insertion/deletion polymorphism in 174 patients with NIDDM and 62 controls were examined with PCR. Results: ACE gene I/D polymorphism was closely related to coronary heart disease (angina, cardiac infarction) and cerebral infarction in diabetic patients but not with hypertension. Plasma renin activity and plasma angiotensin II levels in complicated diabetic patients with ACE D/D gene were significantly higher than those in the controls (p < 0.01). Their aldosterone and endothelin contents were not significantly different. Conclusion: Examination of ACE gene I/D polymorphism was useful for the primary prevention of cardio-brain complications in diabetic patients and helpful in the early diagnosis and therapy of coronary heart disease and cerebral infarction

  12. Early elective colostomy following spinal cord injury.

    Science.gov (United States)

    Boucher, Michelle

    Elective colostomy is an accepted method of bowel management for patients who have had a spinal cord injury (SCI). Approximately 2.4% of patients with SCI have a colostomy, and traditionally it is performed as a last resort several years after injury, and only if bowel complications persist when all other methods have failed. This is despite evidence that patients find a colostomy easier to manage and frequently report wishing it had been performed earlier. It was noticed in the author's spinal unit that increasing numbers of patients were requesting colostomy formation during inpatient rehabilitation following SCI. No supporting literature was found for this; it appears to be an emerging and untested practice. This article explores colostomy formation as a method of bowel management in patients with SCI, considers the optimal time for colostomy formation after injury and examines issues for health professionals.

    To assess whether an additional chest ultra-low-dose CT scan to the coronary CT angiography protocol can be used for lung cancer screening among patients with suspected coronary artery disease. 175 patients underwent coronary CT angiography for assessment of coronary artery disease, additionally undergoing ultra-low-dose CT screening to early diagnosis of lung cancer in the same scanner (80kVp and 15mAs). Patients presenting pulmonary nodules were followed-up for two years, repeating low-dose CTs in intervals of 3, 6, or 12 months based on nodule size and growth rate in accordance with National Comprehensive Cancer Network guidelines. Ultra-low-dose CT identified 71 patients with solitary pulmonary nodules (41%), with a mean diameter of 5.50±4.00mm. Twenty-eight were >6mm, and in 79% (n=22) of these cases they were false positive findings, further confirmed by follow-up (n=20), resection (n=1), or biopsy (n=1). Lung cancer was detected in six patients due to CT screening (diagnostic yield: 3%). Among these, four cases could not be detected in the cardiac field of view. Most patients were in early stages of the disease. Two patients diagnosed at advanced stages died due to cancer complications. The addition of the ultra-low-dose CT scan represented a radiation dose increment of 1.22±0.53% (effective dose, 0.11±0.03mSv). Lung cancer might be detected using additional ultra-low-dose protocols in coronary CT angiography scans among patients with suspected coronary artery disease. Copyright © 2017 Elsevier B.V.

    Qualitative distribution of coronary flow using thallium-201 perfusion scans immediately postintubation was studied in 22 patients scheduled for elective coronary artery bypass surgery. Ten patients received a thiopental (4 mg/kg) and halothane induction. Twelve patients received a fentanyl (100 micrograms/kg) induction. Baseline thallium-201 perfusion scans were performed 24 h prior to surgery. These scans were compared with the scans performed postintubation. A thallium-positive scan was accepted as evidence of relative hypoperfusion. Baseline hemodynamic and ECG data were obtained prior to induction of anesthesia. These data were compared with the data obtained postintubation. Ten patients developed postintubation thallium-perfusion scan defects (thallium-positive scan), even though there was no statistical difference between their baseline hemodynamics and hemodynamics at the time of intubation. There was no difference in the incidence of thallium-positive scans between those patients anesthetized by fentanyl and those patients anesthetized with thiopental-halothane. The authors conclude that relative hypoperfusion, and possibly ischemia, occurred in 45% of patients studied, despite stable hemodynamics, and that the incidence of these events was the same with two different anesthetic techniques.

    2018-01-01

    Full Text Available BACKGROUND Present study is an attempt to throw light upon the coronary arterial pattern, variations in arterial distribution and extent of intercoronary anastomosis and arterial preponderance in different age groups. MATERIALS AND METHODS Total of 115 hearts were made use for this study. Ninety hearts were dissected for the gross anatomical study of coronary arteries and 25 hearts including three fetal hearts were used for the coronary cast study. The right and left coronary arteries were traced from aortic sinus along the atrioventricular groove to the area of its termination. The atrial ventricular and septal branches were traced and looked for anastomosis. Coronary casts were prepared by injecting coloured liquid latex through the coronary ostia and the branching pattern and anastomosis were studied. The coronary arterial pattern, extent of distribution of its branches, arterial preponderance and variations were observed. RESULTS It was found that 73 % cases of SA nodal branch arise from right coronary artery and 27 % from circumflex branch of left coronary artery. SA node has dual blood supply from both coronary arteries in 4% cases. Right coronary preponderance was observed in 83% of cases and left coronary preponderance in 11 % cases, and balanced supply in 6% cases. Coronary cast was helpful to understand the branching pattern of vessels, and the anastomosis of small capillaries. It was also seen that all 11 % of left preponderance were seen in male hearts and all of the 31 female hearts dissected were right preponderant. CONCLUSION Coronary arteries are called end arteries functionally. Right coronary artery originates from anterior aortic sinus in all cases except one which takes origin from posterior left aortic sinus along with left coronary artery. Right coronary preponderance is observed in 83% cases. Left coronary artery branching pattern shows variability. Left coronary preponderance was observed in 11% and all cases are male

    Minimally invasive approaches to treat vascular disease have been accruing significant popularity over the last several decades. Due to progressive advances in technology, a variety of techniques are being now utilized in the field of cardiovascular surgery. The objectives of minimally invasive techniques are to curtail operative trauma and minimize perioperative morbidity without decreasing the quality of the treatment. The standard surgical approach for the treatment of coronary artery disease has traditionally been coronary artery bypass grafting surgery via median sternotomy. Off-pump coronary artery bypass grafting surgery offers a less invasive alternative and enables coronary revascularization to be performed without cardiopulmonary bypass. Hybrid coronary revascularization offers an even less invasive option in which minimally invasive direct coronary artery bypass can be combined with percutaneous coronary intervention. In this article, the authors review a recent publication comparing hybrid coronary revascularization and off-pump coronary artery bypass grafting surgery.

    Some authors state that elective laparoscopic recto-sigmoid resection is more difficult for diverticular disease as compared with malignancy. For this reason, starting laparoscopic surgeons might avoid diverticulitis, making the implementation phase unnecessary long. The aim of this study was to determine whether laparoscopic resection for diverticular disease should be included during the implementation phase. All consecutive patients who underwent an elective laparoscopic recto-sigmoid resection in our hospital for diverticulitis or cancer from 2003 to 2007 were analysed. A total of 256 consecutive patients were included in this prospective cohort study. One hundred and fifty-one patients were operated on for diverticulitis and 105 for cancer. There was no significant difference in operation time (168 vs. 172 min), blood loss (189 vs. 208 ml), conversion rates (9.9% vs. 11.4%), hospital stay (8 vs. 8 days), total number of peroperative (2.3% vs. 1.6%) or postoperative complications (21.9% vs. 26.9%). The occurrence of anastomotic leakages was associated with higher American Society of Anesthesiologists (ASA) classification, which differed between the groups (86.8% vs. 64.8% ASA I-II, p < 0.001). Since there are no differences in operation time, blood loss, conversion rate and total complications, there is no need to avoid laparoscopic recto-sigmoid resection for diverticular disease early in the learning curve.

    Full Text Available Abstract Background Apical ballooning syndrome (or Takotsubo cardiomyopathy is a syndrome of transient left ventricular apical ballooning. Although first described in Japanese patients, it is now well reported in the Caucasian population. The syndrome mimicks an acute myocardial infarction but is characterised by the absence of obstructive coronary disease. We describe a serious and poorly understood complication of Takotsubo cardiomyopathy. Case Presentation We present the case of a 65 year-old lady referred to us from a rural hospital where she was treated with thrombolytic therapy for a presumed acute anterior myocardial infarction. Four hours after thrombolysis she developed acute pulmonary oedema and a new systolic murmur. It was presumed she had acute mitral regurgitation secondary to a ruptured papillary muscle, ischaemic dysfunction or an acute ventricular septal defect. Echocardiogram revealed severe mitral regurgitation, left ventricular apical ballooning, and systolic anterior motion of the mitral valve with significant left ventricular outflow tract gradient (60–70 mmHg. Coronary angiography revealed no obstructive coronary lesions. She had an intra-aortic balloon pump inserted with no improvement in her parlous haemodynamic state. We elected to replace her mitral valve to correct the outflow tract gradient and mitral regurgitation. Intra-operatively the mitral valve was mildly myxomatous but there were no structural abnormalities. She had a mechanical mitral valve replacement with a 29 mm St Jude valve. Post-operatively, her left ventricular outflow obstruction resolved and ventricular function returned to normal over the subsequent 10 days. She recovered well. Conclusion This case represents a serious and poorly understood association of Takotsubo cardiomyopathy with acute pulmonary oedema, severe mitral regurgitaton and systolic anterior motion of the mitral valve with significant left ventricular outflow tract obstruction.

    Acute kidney injury (AKI) is a common complication after coronary angiography. Early biomarkers of this disease are needed since increase in serum creatinine levels is a late marker. To assess the usefulness of urinary kidney injury molecule-1 (uKIM-1), neutrophil gelatinase-associated lipocalin (uNGAL) and liver-type fatty acid-binding protein (uL-FABP) for early detection of AKI in these patients, comparing their performance with another group of cardiac surgery patients. Biomarkers were measured in 193 patients, 12 h after intervention. In the ROC analysis, AUC for KIM-1, NGAL and L-FABP was 0.713, 0.958 and 0.642, respectively, in the coronary angiography group, and 0.716, 0.916 and 0.743 in the cardiac surgery group. Urinary KIM-1 12 h after intervention is predictive of AKI in adult patients undergoing coronary angiography, but NGAL shows higher sensitivity and specificity. L-FABP provides inferior discrimination for AKI than KIM-1 or NGAL in contrast to its performance after cardiac surgery. This is the first study showing the predictive capacity of KIM-1 for AKI after coronary angiography. Further studies are still needed to answer relevant questions about the clinical utility of biomarkers for AKI in different clinical settings.

  8. Nigeria and Democratic Progress by Elections in Africa

    2016-01-01

    Full Text Available Elections do not always advance democratisation, yet they can. We outline a democratisation-by-elections model according to which the opportunities for political change opened up by each electoral round build on previous election-related democratic progress. We focus on Nigeria, interpret the recent executive turnover in light of previous elections, and set the country within the comparative context of Africa’s democratisation. Using a new Africa Leadership Change dataset, we use election-related events to examine the diverse routes that African regimes have taken since 1990. The analysis highlights two major syndromes: democratic stagnation and recession. In a sizeable group, however, the institutionalisation of democracy has been making gradual progress. While there is no predetermined way to advance democracy, the reiteration of elections can be instrumental in such advancement.

    The aim of this study was to establish whether smoking is associated with complicated diverticular disease and adverse outcomes of operative treatment of diverticular disease. Smoking has been associated with increased rate of perforations in acute appendicitis as well as failure of colonic anastomosis in patients resected for colonic tumours. It has also been suggested that smoking is a risk factor for complicated diverticular disease of the colon. Retrospective investigation of records of 261 patients electively operated for diverticular disease in Helsinki University Central Hospital during a period of five years. The smokers underwent sigmoidectomy at a younger age than the non-smokers (p = 0.001) and they had an increased rate of perforations (p = 0.040) and postoperative recurrent diverticulitis episodes (p = 0.019). We conclude that smoking increases the likelihood of complications in diverticulosis coli. The development of complicated disease also seems to proceed more rapidly in smokers.Key words: Sigmoid resection; laparoscopy; laparoscopic sigmoidectomy; smoking and diverticular disease; complicated diverticular disease; diverticulitis.

  11. Perioperative outcomes in minimally invasive direct coronary artery bypass versus off-pump coronary artery bypass with sternotomy.

    Surgical treatment of isolated left anterior descending coronary artery disease can be performed with either minimally invasive direct coronary artery bypass via a left anterior thoracotomy (MIDCAB) or off-pump coronary artery bypass via a median sternotomy (OPCAB). To compare the perioperative outcomes of patients undergoing MIDCAB or OPCAB surgery. Patients who underwent either MIDCAB or OPCAB for isolated left anterior descending (LAD) coronary artery disease between October 2013 and December 2015 were retrospectively evaluated. Operations were carried out by the same surgical team. Preoperative, intraoperative and postoperative data of the patients were recorded for analyses. Twenty-three patients (7 females, 16 males) underwent MIDCAB surgery, and 24 patients (4 female, 20 males) underwent OPCAB surgery. The two groups were comparable regarding preoperative patient characteristics. Duration of mechanical ventilation (5.1 ±0.7 h vs. 6.6 ±0.9 h), intensive care unit stay (19.4 ±2.5 h vs. 45.8 ±5.4 h) and hospital stay (4.3 ±0.4 days vs. 5.6 ±0.8 days) were significantly shorter in the MIDCAB group (p < 0.01). Patients in the OPCAB group required significantly more blood transfusions (1.83 ±0.38 units vs. 0.17 ±0.38 units) and fresh frozen plasma use (2.33 ±0.96 units vs. 0.69 ±0.76 units) (p < 0.01). Conversion to sternotomy was not required in the MIDCAB group. There was no mortality, conversion to cardiopulmonary bypass or serious complication in either group. We believe that the MIDCAB technique is more advantageous than the OPCAB technique in the treatment of patients with a critical LAD lesion.

    Diabetic nephropathy is found to be significantly associated withdiabetic retinopathy and coronary artery disease. Few studies have also shownan association between diabetic nephropathy and neuropathy and peripheralvascular disease. A cross sectional study was done among consecutive type 2diabetics presenting to Christian Medical College and Hospital, Ludhiana fromJune 2004 to may 2005. Patients were subjected to the clinical and laboratoryinvestigations 174 patients were studied over a period of one year. Diabeticnephropathy was found to be associated with proliferative diabeticretinopathy, neuropathy and cardiovascular disease by univariate analysis. Inmultivariate analysis, diabetic nephropathy was again sufficiently associatedwith proliferative diabetic retinopathy and coronary artery disease. Weconclude that close association between diabetic nephropathy and other microand macrovascular complications exists in our Indian patients also. (author)

    The last elections, on 9 March 2008, were the first Spanish general elections where the Internet played a major role in the electoral campaign. It entered in the campaign in a way different from how it had done up until then, not just in general elections, but in any election in Spain.

    Even though political parties continued to have their web pages, with news, biographies of the candidates, planned events, electoral programme, etc., five clear changes were observed in how the campaigns were run online, changes which have also been observed in other countries.

    Full Text Available In the following article the author covers the process of counting the votes and the disclosure rules of establishment the election results in the Swiss Confederation. Switzerland along with other EU member states pays special attention to the determination of the election results. According to Art. 149 para. 2 Federal Constitution of the Swiss Confederation the elections to the National Council, which is one of two chambers of the Federal Assembly, are held according to proportional representation system. The Hagenbach-Bischoff system is used for allocating seats in National Council of the Swiss Con federation. However the above mentioned system for determining the quota of votes per each mandate creates ambiguous opinions among Swiss scientists and legal experts, which frequently comes up in discussions whether to modify it or not. In this article, the author also gives a brief description of the main political parties in Switzerland and statistics of seats allocation in 49 legislature of National Council following the elections of October 23, 2011. As a result, the author provides the full information on the process of votes counting and establishment of election results in the Swiss Confederation. The material presented in this article is particularly interesting and relevant in terms of improving the electoral legislation in the Russian Federation. The information presented by the author will be useful to all parties interested in electoral law.

    2003-01-01

    The aim of the study is the assessment of the methodology for the C-TIMI frame count by Gibson for easy and fast determination of the coronary blood flow during a selective coronary angiography. 75 patient have been studied with one-branch affection of the coronary arteries. The criteria for exclusion are: myocardial hypertrophy, valve lesions, myocardial infarction and dyslipidemia. Depending of the characteristics of the coronary stenotic changes, the patients have been divided into two groups: 1) Patients with 'ordinary' stenosis of the coronary artery and 2) Patients with 'complex' stenosis. The severity of the stenotic changes in percents is the same for the two groups - 78%±13% vs 81±12%, respectively. In the first group a pronounced correlation is observed between the severity of the coronary stenosis and the slowing of the coronary blood flow. The 'threshold' stenotic level is 89%. In the second group the lowest value of the coronary stenosis is 73% (p>0.01 vs group 1). No correlation is observed between the severity of the coronary stenosis and the slowing of the coronary blood flow. A conclusion is made that the Gibson method for the assessment of the blood flow is convenient for the daily practice not only for the assessment of the significance of the coronary changes, but also for fast analysis of the achieved reconstruction of the coronary arteries after angioplasty. Additional studies of the significance of the different signs of 'complexity' of the coronary stenosis for the slowing of the blood flow are necessary

    2005-01-01

    Purpose. To Evaluate the MELD score as a predictor of 30-day mortality in patients undergoing elective TIPS procedures. Methods. This was a retrospective, IRB-approved study. The medical records of all patients who underwent a TIPS procedure between May 1, 1999 and June 1, 2003 in a single institution were reviewed. Patients who underwent elective TIPS were selected. Elective TIPS was performed in 119 patients with a mean age of 55.1 (± 9.6) years. The MELD and Child-Pugh scores before TIPS, etiology of cirrhosis, portosystemic gradients before and after TIPS, procedure time, and procedural complications were obtained from the medical records. The MELD and Child-Pugh scores before TIPS were compared between the survivor group (SG) and the early death (EDG) group. The early death rate was calculated for MELD score subgroups (1-10, 11-17, 18-24, and >24). Data were analyzed using the Fisher exact test, chi-square test and independent-sample t-test. A p value of less than 0.05 was considered significant. Results. Technical success rate was 100%. The early death rate was 10.9% (13/119). The mean MELD scores before TIPS were 19.4 (± 5.9) (EDG) and 14 (± 4.2) (SG) (p = 0.025). The early death rate was highest in the pre-TIPS MELD > 24 subgroup. The Child-Pugh scores were 9.0 (± 1.6) (SG) and 9.8 ± 1.06 (EDG) (p 0.08). The mean portosystemic gradients before TIPS were 20.5 (± 7.7) mmHg (EDG) and 22.7 (± 7.3) (SG) (p > 1) and the mean portosystemic gradients after TIPS were 6.5 (± 3.5) (EDG) and 6.9 (± 2.4) (SG) (p > 1). The mean procedural times were 95.6 (± 8.4) min (EDG) and 89.2 (± 7.5) min (SG) (p > 1). No early death was attributed to a fatal complication during TIPS. Conclusion. The MELD score is useful in identifying patients at a higher risk of early death after an elective TIPS. On the basis of our results, we do not endorse elective TIPS in patients with MELD scores > 24

  2. Carotid and coronary disease management prior to open and endovascular aortic surgery. What are the current guidelines?

    Thompson, J P

    2014-04-01

    Several bodies produce broadly concurring and updated guidelines for the evaluation and treatment of cardiovascular disease in both surgical and non-surgical patients. Recent developments include revised recommendations on preoperative stress testing, referral for possible coronary revascularization and medical management. It is recognized that non-invasive cardiac tests are relatively poor at predicting perioperative risk, and "prophylactic" coronary revascularization has a limited role. The planned aortic intervention (open or endovascular repair) also influences preoperative management. Patients presenting for elective abdominal aortic aneurysm (AAA) repair should only be referred for cardiological testing if they have active symptoms of coronary artery disease (CAD), known CAD and poor functional exercise capacity, or multiple risk factors for CAD. Coronary revascularization before AAA surgery should be limited to patients with established indications, so cardiac stress testing should only be performed if it would change management i.e. the patient is a candidate for and would benefit from coronary revascularization. When endovascular aortic repair is planned, it is reasonable to proceed to surgery without further cardiac stress testing or evaluation unless otherwise indicated. All non-emergency patients require medical optimization, but perioperative beta blockade benefits only certain patients. Some of the data informing recent guidelines have been questioned and some guidelines are being revised. Current guidelines do not specifically address the management of patients with known or suspected carotid artery disease who may require aortic surgery. For these patients, an individualized approach is required. This review considers recent guidelines. Algorithms for investigation and management based on their recommendations are included.

    Directory of Open Access Journals (Sweden)

    Gianluca Pontone

    2015-01-01

    Full Text Available Coronary artery disease (CAD is one of the leading causes of morbidity and mortality and it is responsible for an increasing resource burden. The identification of patients at high risk for adverse events is crucial to select those who will receive the greatest benefit from revascularization. To this aim, several non-invasive functional imaging modalities are usually used as gatekeeper to invasive coronary angiography, but the diagnostic yield of elective invasive coronary angiography remains unfortunately low. Stress myocardial perfusion imaging by cardiac magnetic resonance (stress-CMR has emerged as an accurate technique for diagnosis and prognostic stratification of the patients with known or suspected CAD thanks to high spatial and temporal resolution, absence of ionizing radiation, and the multiparametric value including the assessment of cardiac anatomy, function, and viability. On the other side, cardiac computed tomography (CCT has emerged as unique technique providing coronary arteries anatomy and more recently, due to the introduction of stress-CCT and noninvasive fractional flow reserve (FFR-CT, functional relevance of CAD in a single shot scan. The current review evaluates the technical aspects and clinical experience of stress-CMR and CCT in the evaluation of functional relevance of CAD discussing the strength and weakness of each approach.

    2000-01-01

    Full Text Available The author argues that the conjugation of certain democratic, socioeconomic and political factors has led to the "nationalization" of presidential elections in Brazil since 1960. The expansion of the electoral market resulting from urbanization and the growth of the electorate, together with the progressive removal of the obstacles to voting - due to income, gender, age, and education - has democratized the electoral process by diversifying the social structure of the electorate. Since then, the president's election has ceased to depend solely upon rural political forces and now involves multiple combinations of rural and urban political forces. Candidates can no longer count on specific social groups in order to guarantee their election, and need to widen their appeal. Based on the results of the direct presidential elections of 1960, 1989, 1994 and 1998, the author contends that the "nationalization" of the vote is part of the political integration of Brazilian society and that this, together with the social complexity of the electorate, means that the candidate's appeal and political stance need to be more wide-ranging in order to prevent potential conflicts from arising during the election campaign.

    2014-01-01

    In The Netherlands, more than 30.000 patients undergo a percutaneous coronary intervention every year, during which a coronary stent implantation will be performed in 90% of the cases. It is estimated that more than 5 million coronary stent implantations will be performed worldwide this year. While these numbers are impressive, however, coronary stents still have as a limitation the possibility of stent thrombosis. This has been and is an important stimulus for the development of both coronary stents, from a bare metal stent via a drug eluting stent to the present-day development of bio-absorbable stents, and anti-platelet drugs,from acenocoumarol to thieropyridines. The possibility of shortening the period of use of this powerful medication by developing new kinds of non-thrombogenic stents would, for example, make it possible to achieve significant reductions in subsequent bleeding during (dental) procedures.

    Full Text Available One of the three clinical examples of hospital thrombolysis using Russian thrombolytic agent recombinant protein comprising an amino acid sequence of staphylokinase is described. The trial was held in Chelyabinsk Regional Vascular Centre of specialized medical care for patients with acute coronary syndromes. Each of the three patients had similar reasons for systemic intravenous thrombolysis: hospitalization with ST-segment elevation myocardial infarction, unavailability of coronary interventions due to the X-ray operating room occupancy, high need for the reperfusion therapy in the setting of significant acute myocardial ischemia. In all the cases the pharmacologic reperfusion with recombinant protein comprising an amino acid sequence of staphylokinase was successful, hereafter percutaneous coronary interventions were performed. There were no complications registered.

    Myocardial infarction (MI) secondary to coronary artery disease remains the leading cause of death in the western world. The advent of early reperfusion therapy has substantially decreased in-hospital mortality and has improved the outcome in survivors of the acute phase of MI. Complications of MI include ischaemic, mechanical, arrhythmic, embolic and inflammatory disturbances. Although some of these complications may be infrequent, their importance is underscored because of the potential ability to correct them with early diagnosis and appropriate treatment. The majority of these complications will be detected on clinical examination and confirmed by echocardiography. Some patients may undergo non-electrocardiogram (ECG)-gated thoracic multidetector-row computed tomography (MDCT) due to non-specific presentation. In this group, it is imperative for the radiologist to be aware of and be confident in diagnosing the complications secondary to MI. This review illustrates the spectrum and imaging features of acute and chronic complications of MI that can be visualized on both ECG-gated cardiac and non-ECG-gated thoracic MDCT.

    BACKGROUND: Coronary Artery Bypass Graft operation for ischemic heart disease provides improved quality of life and, in some patients, prolonged survival. Concern has, however, been raised about complications that may be related to the use of cardiopulmonary by-pass (CPB) and aortic cross......-clamping. It has been hypothesized that when coronary artery by-pass grafting is performed without the use of CPB, the rate of serious complications is reduced. METHODS/DESIGN: The trial is designed as an open, randomized, controlled, clinical trial with blinded assessment of end-points. Patients at or above 70...... years of age, referred for surgical myocardial revascularisation, are included and randomised to receive coronary artery by-pass grafting either with or without the use of CPB and aortic cross-clamping. Follow-up is performed by clinical, biochemical, electrocardiographic, and angiographic data...

    Anomalous aortic origin of the coronary arteries is uncommon but clinically significant. Manifestations vary from asymptomatic patients to those who present with angina pectoris, myocardial infarction, heart failure, syncope, arrhythmias, and sudden death. We describe 4 patients, aged 34 to 59 years, who were diagnosed with right coronary artery arising from the left sinus of Valsalva, confirmed by coronary angiography, which was surgically repaired. Three patients presented dyspnea and angina, and one with acute myocardial infarction. At operation, the right coronary artery was dissected at the take-off from the intramural course, and reimplanted into the right sinus of Valsalva. There was no mortality. One patient had associated coronary artery disease that required stent placement postoperatively. This reimplantation technique provides a good physiological and anatomical repair, eliminates a slit-like ostium, avoids compression of the coronary artery between the aorta and the pulmonary artery, and gives superior results to coronary artery bypass grafting or the unroofing technique.

    The arterial ligation during elective laparoscopic sigmoidectomy for diverticular disease can affect genito-urinary function injuring the superior hypogastric plexus, and can weaken the distal colonic stump arterial perfusion. Ligation of the inferior mesenteric artery distal to the left colic artery or the complete preservation of the inferior mesenteric artery can therefore be compared in terms of preservation of the descending sympathetic fibres running along the aorta to the rectum resulting in a different post operative genito urinary function. From January 2015 to March 2016, 66 patients underwent elective laparoscopic sigmoidectomy for diverticular disease among two enrolling hospitals. In one centre 35 patients underwent laparoscopic sigmoidectomy with the ligation of the inferior mesenteric artery distal to the left colic artery (low ligation). In the other centre 31 patient were operated on the same procedure with complete inferior mesenteric artery preservation (IMA preservation). There was no difference in terms of major complication occurred, first passage of stool and length of hospital stay between the two groups. Time of surgery was significantly shorter in LL group compared to IMA preserving group and intra operative blood loss was significantly lower in the LL group. There were no differences in the genito urinary function between the two group pre operatively, at 1 and 9 months post operatively. Genito urinary function did not significantly change across surgery in each groups. The low ligation and the IMA preserving vascular approach are safe end feasible techniques in elective laparoscopic sigmoidectomy for diverticular disease. They both prevent from genito-urinary post-operative disfunction and allow good post operative quality of life. The low ligation approach is related to shorter operative time and slower intra operative blood loss. Celsius.

    Pulmonary complications, especially postoperative pulmonary complications, are an important cause of morbidity and mortality in neurosurgical patients. Hypoxemia due to mucus plug causing lung collapse is a rare event. We report a case of a 40-year-old female with right cerebellopontine angle space occupying lesion, scheduled for elective craniotomy and tumor excision. The patient underwent surgery uneventfully and was shifted to Intensive Care Unit (ICU) for monitoring. Eight hours after extubation, she developed hypoxemia due to mucus plug resulting in left lung collapse. She was intubated, and mucus plug was aspirated through sterile endobronchial tube suction which resulted in reexpansion of the collapsed lung. The patient was managed with postural drainage, chest physiotherapy, and antibiotics and extubated after 24 h. This type of pulmonary complication may have a catastrophic course, especially in neurosurgical patients, if not diagnosed and managed in time.

  20. Impact of pacing modality and biventricular pacing on cardiac output and coronary conduit flow in the post-cardiotomy patient.

    We have previously demonstrated the role of univentricular pacing modalities in influencing coronary conduit flow in the immediate post-operative period in the cardiac surgery patient. We wanted to determine the mechanism of this improved coronary conduit and, in addition, to explore the possible benefits with biventricular pacing. Sixteen patients undergoing first time elective coronary artery bypass grafting who required pacing following surgery were recruited. Comparison of cardiac output and coronary conduit flow was performed between VVI and DDD pacing with a single right ventricular lead and biventricular pacing lead placement. Cardiac output was measured using arterial pulse waveform analysis while conduit flow was measured using ultrasonic transit time methodology. Cardiac output was greatest with DDD pacing using right ventricular lead placement only [DDD-univentricular 5.42 l (0.7), DDD-biventricular 5.33 l (0.8), VVI-univentricular 4.71 l (0.8), VVI-biventricular 4.68 l (0.6)]. DDD-univentricular pacing was significantly better than VVI-univentricular (P=0.023) and VVI-biventricular pacing (P=0.001) but there was no significant advantage to DDD-biventricular pacing (P=0.45). In relation to coronary conduit flow, DDD pacing again had the highest flow [DDD-univentricular 55 ml\\/min (24), DDD-biventricular 52 ml\\/min (25), VVI-univentricular 47 ml\\/min (23), VVI-biventricular 50 ml\\/min (26)]. DDD-univentricular pacing was significantly better than VVI-univentricular (P=0.006) pacing but not significantly different to VVI-biventricular pacing (P=0.109) or DDD-biventricular pacing (P=0.171). Pacing with a DDD modality offers the optimal coronary conduit flow by maximising cardiac output. Biventricular lead placement offered no significant benefit to coronary conduit flow or cardiac output.

    Homocystein is at the crossroads of the metabolic pathways of sulphuric amino acids. Homocystinuria is a congenital autosomal recessive disease, usually related to cystathionine beta-synthetase deficiency. Children with homozygotic forms of the disease have early vascular complications which represent the main cause of death. Moderately elevated serum homocystein levels are related to two major genetic factors (heterozygotic cystathionine beta-synthetase deficiency and mutation of the 5-10 methylene tetrahydrofolate reductase) and several minor, genetic and non-genetic factors (folic acid, vitamins B6 and B12 and betain deficiencies). Previous studies have suggested that hyperhomocysteinaemia could be a cardiovascular risk factor. This study was based on 222 subjects including 102 consecutive patients with angiographically documented coronary artery disease and 120 control subjects without vascular disease. No relationship was observed between serum homocystein concentrations and the classical cardiovascular risk factors. Coronary patients had higher average homocystein concentrations than control subjects (11.27 +/- 0.52 vs 8.77 +/- 0.31 mumol/l); p 15.67 mumol/l) was higher in the coronary group (15.7%) than in the controls (2.5%). A significant relationship was also observed between homocystein concentrations and the severity of the coronary disease (defined by a coronary score) and the number of diseased vascular territories. These results underline the relationship between homocystein and vascular risk, especially that of coronary artery disease. The treatment of hyperhomocysteinaemia by folic acid supplements is effective in correcting plasma levels, without side effects and at a relatively low cost.

    The study aims to determine the direct costs and comparative cost-effectiveness of latest-generation dual-source computed tomography (DSCT) and invasive coronary angiography for diagnosing coronary artery disease (CAD) in patients suspected of having this disease. The study was based on a previously elaborated cohort with an intermediate pretest likelihood for CAD and on complementary clinical data. Cost calculations were based on a detailed analysis of direct costs, and generally accepted accounting principles were applied. Based on Bayes' theorem, a mathematical model was used to compare the cost-effectiveness of both diagnostic approaches. Total costs included direct costs, induced costs and costs of complications. Effectiveness was defined as the ability of a diagnostic test to accurately identify a patient with CAD. Direct costs amounted to €98.60 for DSCT and to €317.75 for invasive coronary angiography. Analysis of model calculations indicated that cost-effectiveness grew hyperbolically with increasing prevalence of CAD. Given the prevalence of CAD in the study cohort (24%), DSCT was found to be more cost-effective than invasive coronary angiography (€970 vs €1354 for one patient correctly diagnosed as having CAD). At a disease prevalence of 49%, DSCT and invasive angiography were equally effective with costs of €633. Above a threshold value of disease prevalence of 55%, proceeding directly to invasive coronary angiography was more cost-effective than DSCT. With proper patient selection and consideration of disease prevalence, DSCT coronary angiography is cost-effective for diagnosing CAD in patients with an intermediate pretest likelihood for it. However, the range of eligible patients may be smaller than previously reported.

    Full text: This review will present the current and future role of cardiac computer tomography (CCT), and particular multidetector CCT, for imaging of atherosclerotic pathologic changes of the coronary arteries. Atherosclerosis and its cardio-vascular complications represent one of the major issues of public health in industrial countries. Different imaging modalities, including invasive coronarography, have been aimed to the diagnosis of the disease, when it provokes symptomatic decrease of the blood flow. In spite of development of surgical and percutaneous methods for coronary revascularization, coronary artery disease remains the major cause of death in North America and Europe. This demonstrates the need of novel, complementary diagnostic strategies, aimed to identify asymptomatic stages as the basis of pharmacological interventions. Noninvasive coronary angiography with multidetector CT allows both assessment of luminal stenosis and subclinical disease of arterial wall. Large trails are missing now to understand and present what will be the role of this technology in the comprehensive assessment of patients, suspected of having CAD. Based on experience and current potentials we will describe how tomographic coronary imaging may eventually supplement traditional angiographic techniques in understanding the patterns of atherosclerotic CAD development

    Coronary magnetic resonance angiography (MRA) has been recently brought into clinical use, however, there has not been reports on the comparison with MRA and conventional contrast coronary angiography (CAG) in the detection of the localization and characteristics of coronary restenosis after percutaneous transluminal coronary angioplasty (PTCA). To assess the restenosis of coronary artery after PTCA, this study compared three-dimensional (3D) coronary MRA and CAG. One hundred three patients (76 males and 27 females, average age of 64.6±9.3 years old) were performed coronary MRA at 3-6 months after PTCA. The right coronary artery (RCA) group consist of 21 patients, the left anterior descending branch (LAD) 63 patients and the left circumflex branch (LCX) 19 patients. Coronary MRA was performed with the patients in supine position on a 1.5 T whole body scanner (MAGNETOM VISION, Siemens AG, Germany) using body array coil. The imaging technique used a 3-D gradient echo sequence with respiratory gating and fat suppression. The slice thickness was 2 mm, slab thickness 32 mm, a field of view of 300 mm and a matrix of 128 x 256. Other parameters were an echo time of 2.7 ms and a repetition time of 600 to 1100 msec. The measurement time of 1 imaging slab took 15 to 20 minutes depending on the patient's heart rate. The coronary arteries were reconstructed from the 3-D data set using a multiplanar reconstruction (MPR) technique. According to previous coronary MRA studies, a significant stenosis with a luminal reduction of ≥50% was assumed if a marked signal reduction or signal loss of a vessel segment was visible. In CAG, 57 of 103 patients showed restenosis. In coronary MRA, 37 of 103 patients demonstrated restenosis. The sensitivity, specificity, positive and negative predictive values were 64.9%, 100%, 100% and 69.6%, respectively. Predictive accuracy was 79.6%. Three-dimensional coronary MRA is useful in a noninvasive diagnostic method to evaluate the coronary

    2014-01-01

    Full Text Available Coronary computed tomography angiography (CCTA has been recently evaluated for its ability to assess coronary plaque characteristics, including plaque composition. Identification of the relationship between plaque composition by CCTA and patient clinical presentations may provide insight into the pathophysiology of coronary artery plaque, thus assisting identification of vulnerable plaques which are associated with the development of acute coronary syndrome. CCTA-generated 3D visualizations allow evaluation of both coronary lesions and lumen changes, which are considered to enhance the diagnostic performance of CCTA. The purpose of this review is to discuss the recent developments that have occurred in the field of CCTA with regard to its diagnostic accuracy in the quantitative assessment of coronary plaques, with a focus on the characterization of plaque components and identification of vulnerable plaques.

    The angiographical findings of 24 patients with coronary artery disease were compared with qualitative and quantitative detection of coronary calcification by ultrafast CT. Doubts concerning the capabilities of the ultrafast CT for a screening of coronary artery disease arise when the results of one third false positive and fase negative findings are considered. Variations in the quantification of coronary calcification were too great to allow a realistic assessment of the degree of stenosis of the coronary arteries. (orig.) [de

    This study sought to investigate the optimal percutaneous coronary intervention (PCI) strategy for true unprotected left main coronary artery (ULMCA) bifurcations. The FAILS-2 was a retrospective multi-center study including patients with ULMCA disease treated with second-generation drug-eluting stents. Of these, we compared clinical outcomes of a provisional strategy (PS; n=216) versus an elective two-stent strategy (E2S; n=161) for true ULMCA bifurcations. The primary endpoint was the incidence of major adverse cardiac events (MACEs) at 3-years. We further performed propensity-score adjustment for clinical outcomes. There were no significant differences between the groups in terms of patient and lesion characteristics. 9.7% of patients in the PS group crossed over to a provisional two-stent strategy. MACEs were not significantly different between groups (MACE at 3-year; PS 28.1% vs. E2S 28.9%, adjusted p=0.99). The rates of target lesion revascularization (TLR) on the circumflex artery (LCX) were numerically high in the E2S group (LCX-TLR at 3-years; PS 11.8% vs. E2S 16.6%, adjusted p=0.51). E2S was associated with a comparable MACE rate to PS for true ULMCA bifurcations. The rates of LCX-TLR tended to be higher in the E2S group although there was no statistical significance. This study sought to compare the clinical outcomes of a provisional strategy (PS) with an elective two-stent strategy (E2S) for the treatment of true unprotected left main coronary artery bifurcations. 377 Patients (PS 216 vs. E2S 161 patients) were evaluated, and 9.7% in the PS group crossed over to a two-stent strategy. E2S was associated with a similar major adverse cardiac event rate at 3-years when compared to the PS strategy (PS 28.1% vs. E2S 28.9%, p=0.99). However, the left circumflex artery TLR rate at 3-year tended to be higher in the E2S group (PS 11.8% vs. E2S 16.6%, p=0.51). Copyright © 2017 Elsevier B.V. All rights reserved.

    Although perioperative myocardial ischaemia (PMI) is a well-known complication following coronary artery bypass grafting (CABG), standard strategies for its diagnosis and treatment are so far not defined. In this study, we sought to evaluate the impact on survival of postoperative coronary angiogram for management of patients with PMI after CABG. Overall, 4028 patients underwent isolated CABG in a single-centre institution between January 2006 and September 2013. A total of 168 (4.2%) patients received postoperative coronary angiogram because of diagnosis of PMI. These patients were matched on the basis of gender, age at surgery and date of surgery, with 336 (1:2 ratio) CABG patients without PMI to determine the impact of the PMI management. A total of 476 grafts were examined (263 venous grafts, 196 internal mammary artery grafts and 17 radial artery grafts). Almost three-quarters of the 168 PMI (74.4%) patients underwent postoperative coronary angiogram within 24 h of surgery. Normal postoperative coronary angiogram, graft failure and new native vessels occlusion were observed in 23.2%, 52.4% and 24.4% of patients, respectively. A total of 30 (17.9%) patients underwent surgical revision of grafts, whereas 60 (35.7%) patients were treated with percutaneous coronary intervention. Eighteen (10.7%) PMI patients died during the hospital stay compared with 6 (1.8%) patients in the non-PMI group. Survival rates at 7 years were 62.5% in the PMI group and 81.1% in non-PMI group (P PMI (P 24 h after surgery) was an independent predictor of poorer mid-term survival (P = 0.008; hazard ratio 3.62, 95% confidence interval 1.41-9.33). PMI after CABG is associated with a significantly poorer survival. A prompt postoperative management must always be considered. Further prospective studies are required to confirm our results. © The Author 2017. Published by Oxford University Press on behalf of the European Association for Cardio-Thoracic Surgery. All rights

    In a democracy, elections are the way in which the collective thought processes of the voters arrive at a decision to direct their government. The author explores how the individual voter assesses and resolves many conflicting internal and external forces to arrive at a vote. The midterm elections of 2010 illustrate the parallel between individual resolution of conflicting forces and the process of a campaign leading to the outcome of an election. The psychodynamic concepts of conflict and compromise, affects, aggression, unconscious forces, mechanisms of defense, superego, and the ego's integrative functions are evident in both the individual voter and the collective electoral process. The author expresses concern about the historical vulnerability of democracies and the unbalancing effect of allowing limitless infusion of anonymous corporate money to pour into campaigns.

    Coronary angiography (CAG) is an invasive diagnostic procedure, which could lead to procedure related complications. One of the well known post-procedural complications is cerebral embolic infarction with or without symptoms. Silent embolic cerebral infarction (SECI) has clinical significance because it can progress to a decline in cognitive function and increase the risk of dementia in the long term. The aim of this study was to detect the incidence and predictors of SECI after diagnostic CAG using diffusion-weighted magnetic resonance imaging (DW-MRI). A total of 197 patients with coronary artery disease who underwent DW-MRI for evaluation of intracranial vasculopathy before coronary artery bypass graft surgery were retrospectively enrolled in the present study. DW-MRI was performed within 48 h after diagnostic CAG. SECI was diagnosed as presence of focal bright high signal intensity in DW-MRI. Patients were divided into groups according to presence/absence of SECI (+ SECI vs. - SECI, respectively). The clinical and angiographic characteristics were analyzed and independent predictors were evaluated. Of the 197 patients, SECI occurred in 20 patients (10.2%) after diagnostic CAG. Age, female gender, frequency of underlying atrial fibrillation, extent of coronary disease, and fluoroscopic time during diagnostic CAG were not different between the + SECI and - SECI groups. Left ventricular ejection fraction was significantly lower in the + SECI group than in the - SECI group (45.9 ± 8.5% vs. 51.4 ± 13.1%, p=0.014) and performance rate of internal mammary artery (IMA) angiography was significantly higher in the + SECI group compared with the - SECI group (85% vs. 37.2%, pSECI (OR=14.642; 95% CI=3.201 to 66.980, p=0.001). The incidence of SECI after diagnostic CAG was not infrequent. Diagnostic CAG with IMA angiography may increase the risk of SECI. Copyright © 2009 Elsevier Ireland Ltd. All rights reserved.

  15. Successful Rotational Atherectomy for an Angulated Calcified Lesion in an Anomalous Right Coronary Artery Using the “Mother-and-Child” Technique

    Full Text Available Percutaneous coronary intervention (PCI involving the anomalous coronary artery is challenging with respect to difficulty in achieving stable catheterization. Rotational atherectomy (RA can facilitate severely calcified lesions to improve stent delivery and stent expansion; however, its utility in tortuous and angulated coronary arteries is limited with difficulty in delivery of the RA burr. The mother-and-child technique is effective for complex PCIs with increased backup force for device delivery in such complicated cases. We report a case of successful rotational atherectomy using the “mother-and-child” technique with a Dio thrombus aspiration catheter for an angulated calcified lesion in an anomalous origin of the right coronary artery.

    2018-04-01

    Background: Coronary heart disease (CHD) constitutes one of the most frequent causes of death for individuals > 60 years. Lifestyle dependent risk factors are key. Hence, cardiac rehabilitation is essential for optimal CHD treatment. However, individuals rarely comprehend their illness. Motivational interviewing promotes illness perception. Aim/Methods: A randomised-controlled study was conducted to determine the effect of motivational interviewing on illness perception. Patients with stable coronary heart disease were consecutively recruited after elective percutaneous transluminal coronary angioplasty (PTCA). The intervention group received a short motivational interview (MI) about the disease and related risk factors as an intervention. The control group had usual treatment. Illness perception was assessed (Illness Perception Questionnaire-Revised) prior to the intervention and six months afterwards. Results: A total of 312 patients (intervention group: n = 148, control group: n = 164) were recruited into the study (mean age: 66.2 years). After the intervention, a significant change was observed in the domain of emotional reactions regarding the disease. Conclusion: To improve illness perception in patients with stable CHD, one short intervention with MI may have an effect. Whether intensifying the MI-intervention is more effective, requires further research.

    Full Text Available The European Parliament (EP elections have registered high rates of abstention and Portugal is no different from all the other EU countries. From a relational marketing paradigm, we have tried to define the concept of local proximity-based political communication, the grounds for a research program based on a quasi-experimental plan aimed at verifying a set of assumptions on the effects of local proximity-based political communication on the mobilization of Portuguese voters for the EP elections of 2004 and 2009. The results are clear: the proximity-based political communication generated significant electoral mobilization in those two elections.

    Full Text Available Cyclooxygenase (COX catalyzes formation of prostaglandins that contribute to the inflammation in atherosclerosis. Our objective was to study whether the functional C variant of the −765G→C polymorphism in the human COX-2 gene associates with the severity of coronary atherosclerosis measured at the coronary artery level. The Helsinki sudden death study autopsy material (n = 300 comprised of Finnish men who died suddenly. The area of atherosclerotic lesions in the coronary arteries was quantitated, and coronary narrowing was measured. The occurrence of myocardial infarction (MI was assessed. Genotyping was by restriction endonuclease analysis. Men carrying the minor C allele had larger areas of complicated lesions (P = .024 and a higher number of coronary arteries that had over 50% stenosis (P = .036 compared to men representing the common GG genotype. The COX-2 polymorphism was not associated with MI. Our data suggest that COX-2 may be involved in plaque growth.

    We propose a methodology for identifying and analysing 'elective' preterm births (PTBs) using administrative data, and apply this methodology to California data with the objective of providing a framework to further explore the potential rationales for early delivery. Using the California linked birth cohorts for 1999, 2002 and 2005, singleton PTBs were identified using birth certificate gestational age ≥ 24 and PTBs increased 27.7% over the 6-year study period, with nearly all cases confined to the late PTB stratum; elective late PTB rates rose from 10.5% to 13.5% of all late PTBs (P PTBs that is 'elective'. This method can be used to explore and monitor potential strategies for the prevention of elective PTB. © 2012 Blackwell Publishing Ltd.

    Full Text Available The aim of this paper is to take a radiograph of Romania presidential elections of 2014, starting from a general framework in which these elections were held, continuing with issues and debates that characterized this context and ending with international reactions regarding the new elected-president in the foreign press and from the officials. This radiograph brings a series of questions: was the final result of these elections an accident? Was it an express of confidence for the successful candidate or the result of discontent with the current political system, a vote of hope? In this regard, I consider absolutely necessary to understand how the president was elected, the reasons behind this choice and especially if the hopes of voters will be reflected in the work of Klaus Iohannis during his term.

    2016-05-01

    In Turner syndrome, cardiovascular complications are the most important causes of early mortality. Congenital cardiovascular abnormalities are found in approximately one third of Turner syndrome patients. Developments in diagnosis and treatment have decreased the rate of mortality related to these abnormalities. In recent years, many papers have mentioned that coronary artery disease developing at early ages in patients with Turner syndrome causes sudden deaths. The patient, a 27-year-old female was admitted to the emergency room with chest pain at rest. She was diagnosed with Turner Syndrome in her teenage years due to amenorrhea. Patients with ECG changes and cardiac enzyme elevations were treated with acute coronary syndrome. The young woman with Turner Syndrome have several risk factors for early Coronary Artery Disease development. In such cases, dramatic results like sudden death or heart attack at an early age may occur in cases of insufficient follow-up and treatment.

    Patients with diabetes mellitus have reduced longevity after acute coronary syndromes and revascularization. However, knowledge of the long-term complication rates and patterns from an everyday life setting is lacking. Consecutive patients undergoing percutaneous coronary intervention included in the Swedish Coronary Angiography Angioplasty Registry (SCAAR) between 2006 and 2010 and with no previous revascularization were prospectively followed up for combined cardiovascular events (first of all-cause mortality, myocardial infarction, stroke, and heart failure) until December 31, 2010. The mean follow-up period was 920 days (SD, 530 days). Differences in background and procedural characteristics were adjusted for in a multivariate Cox regression model. Of 58 891 patients, mean age 67 years, 19% had diabetes mellitus; 27% of them were on diet treatment, 33% on oral glucose lowering, and 40% on insulin treatment. At admission, cardiovascular risk factors, multiple coronary vessel, and left main stem disease were more frequent in patients with diabetes mellitus and their revascularization was less often complete. The adjusted risk for combined cardiovascular events was higher in patients on insulin (hazard ratio [95% confidence interval], 1.63 [1.55-1.72]), on oral treatment (1.23 [1.15-1.31]), and on diet alone (1.21 [1.12-1.29]) compared with patients without diabetes mellitus. Insulin-treated patients ran an increased risk of restenosis (1.54 [1.39-1.71]) and stent thrombosis (1.56 [1.25-1.96]). The prognosis after a first percutaneous coronary intervention is more severe in patients with diabetes mellitus, in particular, in patients treated with insulin, with higher rates of mortality, cardiovascular events, and stent thrombosis over the following 5 years. © 2015 American Heart Association, Inc.

    This study was designed to investigate the efficacy of cilostazol on the prevention of in-stent neointimal hyperplasia as measured by both quantitative coronary angiography (CAG) and volumetric intravascular ultrasound (IVUS). Fifty-nine patients (39 men, age 62 years) undergoing elective coronary stenting were randomly assigned to receive aspirin plus clopidogrel or ticlopidine (Group I, n=28, 30 lesions) or aspirin plus clopidogrel or ticlopidine plus cilostazol (Group II, n=31, 35 lesions). CAG and IVUS were performed and repeated at 6 months to assess the primary endpoints of minimal luminal diameter (MLD) and in-stent neointimal hyperplasia volume. Follow-up CAG was performed on all patients and follow-up IVUS study was available for 50 lesions in 48 patients (24 lesions in Group I, 26 in Group II). There were no significant differences in the baseline angiographic data between the 2 groups. At 6 months follow-up, in-stent MLD was 1.90±0.76 mm in Group I and 2.41±0.85 mm in Group II (p=0.006). Volumetric IVUS at 6 months demonstrated that in-stent intimal hyperplasia volume per stent length was 2.2±1.4 mm 3 /mm in Group I and 1.0±0.5 mm 3 /mm in Group II (p=0.001). Triple antiplatelet therapy including cilostazol seems to be more effective at preventing in-stent neointimal hyperplasia than a dual antiplatelet regimen. (author)

  14. The effect of two different glycemic management protocols on postoperative cognitive dysfunction in coronary artery bypass surgery

    Directory of Open Access Journals (Sweden)

    Pinar Kurnaz

    Full Text Available Abstract Introduction: Postoperative cognitive dysfunction (POCD is an adverse outcome of surgery that is more common after open heart procedures. The aim of this study is to investigate the role of tightly controlled blood glucose levels during coronary artery surgery on early and late cognitive decline. Methods: 40 patients older than 50 years undergoing elective coronary surgery were randomized into two groups. In the "Tight Control" group (GI, the glycemia was maintained between 80 and 120 mg dL-1 while in the "Liberal" group (GII, it ranged between 80-180 mg dL-1. A neuropsychological test battery was performed three times: baseline before surgery and follow-up first and 12th weeks, postoperatively. POCD was defined as a drop of one standard deviation from baseline on two or more tests. Results: At the postoperative first week, neurocognitive tests showed that 10 patients in the GI and 11 patients in GII had POCD. The incidence of early POCD was similar between groups. However the late assessment revealed that cognitive dysfunction persisted in five patients in the GII whereas none was rated as cognitively impaired in GI (p = 0.047. Conclusion: We suggest that tight perioperative glycemic control in coronary surgery may play a role in preventing persistent cognitive impairment.

    Stent implantation is an effective therapy for aortic coarctation and recoarctation. However, in adolescents and adults, aortic wall rupture and dissection can occur, as well as aneurysms during follow-up. In order to reduce these complications, we electively implant covered stents. Since 2005, we have performed the procedure using femoral access in 17 patients (2 adolescents and 15 adults), 16 electively and 1 as a rescue procedure. We used the Mullins technique in all cases, implanting a NuMED(®) covered stent. Good stent apposition was achieved in all 17 procedures; 8 patients required a distal flare. Gradient was reduced from 40 (16) mmHg to 2 (2) mmHg (P<.001) and lumen diameter increased from 4 (2) mm to 19 (3) mm (P<.001). Two exceptional cases are discussed: one patient with aortic wall rupture who underwent a rescue procedure using a stent within a covered stent and another patient with total obstruction and intercostal aneurysm in whom the outcome was fatal at 48 h postprocedure (autopsy is shown). Four-year clinical follow-up included Doppler echocardiography; an additional imaging technique was required in 13 patients. All patients recovered well and there were no complications. Covered stents are effective in treating coarctation and recoarctation in adolescents and adults, are the treatment of choice in patients with complex anatomy, and must be available in the operating room as a rescue device when implanting a conventional stent.

    Christoph Langer

    Full Text Available Transradial coronary angiography (TRC can be performed with a one-catheter approach for the right and left coronary ostium (R/LCO. We investigated the performance of a special diagnostic catheter widely used for the one-catheter-approach, the Tiger (Tiger II, TerumoTM.In a dual center registry we analyzed 1412 TRC-procedures exclusively performed by experienced TRC-operators. We compared the performance of the Tiger with Judkins catheters by retrospectively judging ostial catheter stability during contrast injection, and by measuring contrast use, fluoroscopy time (FT and complication rate.Poor or failed ostial engagement was found in 40.5% in the Tiger group, compared to 46.6% with the use of Judkins catheters (p<0.183. Ostial instability of the Tiger was found more often during engagement of the LCO than the RCO (34.4% vs. 10.8%, p<0.001, whereas it was similar in the LCO and RCO for Judkins catheters (27.4% vs. 26.7%, p = 0.840. TRC-procedures performed with Tiger catheters were associated with less contrast volume (63.48 ± 29.83mL vs. 82.51 ± 56.58mL, p<0.004 and shorter FT than with Judkins catheters. (198.27 ± 194.8sec vs. 326.85 ± 329.70sec. Forearm hematomas occurred less often with the Tiger (1.2% vs. 6.6%, p< 0.02.The Tiger employed as a single catheter in TRC is an effective tool to achieve lower contrast volume and fluoroscopy time at a low complication rate. Unstable engagement affects predominantly the left coronary artery, but its overall frequency is similar for both, the Tiger and Judkins catheters.

    Purpose: visualization of coronary blood flow by means of a slice-selective inversion pre-pulse in concert with bright-blood coronary MRA. Materials and methods: coronary magnetic resonance angiography (MRA) of the right coronary artery (RCA) was performed in eight healthy adult subjects on a 1.5 Tesla MR system (Gyroscan ACS-NT, Philips Medical Systems, Best, NL) using a free-breathing navigator-gated and cardiac-triggered 3D steady-state free-precession (SSFP) sequence with radial k-space sampling. Imaging was performed with and without a slice-selective inversion pre-pulse, which was positioned along the main axis of the coronary artery but perpendicular to the imaging volume. Objective image quality parameters such as SNR, CNR, maximal visible vessel length, and vessel border definition were analyzed. Results: in contrast to conventional bright-blood 3D coronary MRA, the selective inversion pre-pulse provided a direct measure of coronary blood flow. In addition, CNR between the RCA and right ventricular blood pool was increased and the vessels had a tendency towards better delineation. Blood SNR and CNR between right coronary blood and epicardial fat were comparable in both sequences. (orig.)
