background according to the previous studies, antihypertensive drugs should be withdrawn before surgery. nowadays it is accepted that some drugs effectively control systemic blood pressure (bp) to assure its desirable therapeutic control. objectives in this study, the effects of captopril, an angiotensin converting enzyme inhibitor (acei), on hemodynamic changes before, during and after the cor...

background: the incidence of coronary artery bypass grafting surgery (cabg) in elderly patients has been increasing. there are contradictory reports on the early outcome of elderly coronary artery patients as compared with their young counterparts. we designed this retrospective study to address this issue. methods: w e retrospectively analyzed the results of 1489 on–pump cabg cases performed a...

background: the incidence of stroke after coronary artery bypass grafting (cabg) is between 0.9% and 6.7%, which significantly increases in-hospital and out-hospital costs. this study was designed to evaluate the prevalence of significant carotid stenosis and its risk factors in cabg. methods: in total, 2044 consecutive patients undergoing elective cabg were investigated through a pre-operative...

background: age is one of the most important factors that have consistently emerged as the most potent predictors of mortality and morbidity after coronary artery bypass graft (cabg) surgery. however, early results of cabg in young patients in comparison with elderly ones have been different in previous surveys. the aim of this study was to compare short-term mortality and morbidity in young ve...

Clinical accuracy, defined as the ability to discriminate between states of health, is the fundamental property of any diagnostic test or system. It is readily expressed as clinical sensitivity and specificity, and elegantly represented by the receiver operating characteristic (ROC) curve. To demonstrate the use of ROC curves, we reexamine a study of the ability of serum lipid and apolipoprotei...

Background—The Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) trial assigned patients with type 2 diabetes mellitus to prompt coronary revascularization plus intensive medical therapy versus intensive medical therapy alone and reported no significant difference in mortality. Among patients selected for coronary artery bypass graft surgery, prompt coronary revascularizat...

BACKGROUND The applicability of international risk scores in heart surgery (HS) is not well defined in centers outside of North America and Europe. OBJECTIVE To evaluate the capacity of the Parsonnet Bernstein 2000 (BP) and EuroSCORE (ES) in predicting in-hospital mortality (IHM) in patients undergoing HS at a reference hospital in Brazil and to identify risk predictors (RP). METHODS Retros...

introduction: anxiety and depression are among major problems encountered by most patients after cardiac surgery. they can have serious consequences for patients’ quality of life, physical and psychological morbidity, and follow-up treatments. accordingly, the present study was conducted to determine the status of depression and the associated factors in coronary artery bypass grafting (cabg) p...

background following coronary artery bypass graft (cabg), patients are at high risk (3.2%-8.3%) for developing hospital-acquired pneumonia (hap) with mortality rate of 24% to 50%. some of routine features in patients undergoing cabg are similar to clinical criteria of center of disease control (cdc) for diagnosis of pneumonia. this may lead to over-diagnosis of pneumonia in these patients. obje...
