BACKGROUND Collaterals limit infarct size, preserve viability, and reduce mortality in patients with acute myocardial infarction. In patients with stable coronary disease, collaterals are associated with less angina and ischemia during angioplasty and fewer ischemic events during follow-up. The role of collaterals has not been studied in patients undergoing off-pump or on-pump bypass surgery. ...

OBJECTIVE To study the prevalence and severity of hyperglycemia in nondiabetic patients undergoing cardiac operation. METHODS In an observational prospective study, 282 non-diabetic patients underwent elective off-pump (n=101) or on-pump (n=181) coronary artery bypass grafting (CABG) surgery from March 2006 to July 2007 in Madani Heart Hospital, Tabriz, Iran. Blood glucose (BG) levels were me...

BACKGROUND Due to advancement of non-surgical methods of coronary revascularization the patients referred for surgery have extensive and complex coronary anatomy. Patients with diffuse atheromatous coronary artery disease required coronary artery reconstruction or coronary endarterectomy (CE). Coronary endarterectomy on beating heart needs skill and better surgical technique. Coronary endartere...

 Abstract Background: Erectile dysfunction (ED) is common in cardiovascular disease (CVD) and indicates a complication of coronary artery bypass graft surgery (CABG). This study was designed to evaluate the status of erectile dysfunction in patients with CAD before and after CABG surgery. Methods: We designed a prospective cohort study on male patients candidates for elective on-pump CABG...

AIMS To assess EuroSCORE performance in predicting in-hospital mortality in on-pump coronary artery bypass grafting (CABG) and off-pump coronary artery bypass grafting (OPCAB). METHODS AND RESULTS Additive and logistic EuroSCORE were computed for consecutive patients undergoing CABG (n = 3440, 75%) or OPCAB (n = 1140, 25%) at our hospital from 1999 to September 2007. The areas under the recei...

INTRODUCTION Antiplatelet therapy after coronary artery bypass graft (CABG) has been used. Little is known about the predictors and efficacy of clopidogrel in this scenario. OBJECTIVE Identify predictors of clopidogrel following CABG. METHODS We evaluated 5404 patients who underwent CABG between 2000 and 2009 at Duke University Medical Center. We excluded patients undergoing concomitant val...

OBJECTIVE It is well known that the presence of carotid artery stenosis increases the risk of perioperative stroke in patients undergoing cardiac surgery with cardiopulmonary bypass. Although off-pump coronary artery bypass grafting (CABG) can avoid the adverse effects of cardiopulmonary bypass, the influence of carotid artery stenosis on the incidence of stroke in patients undergoing off-pump ...

background: sexual dysfunction is one of the most common problems in men after coronary artery bypass graft (cabg). etiology of sexual dysfunction in these patients may be psychological or organic due to hormonal changes. objective: the purpose was to evaluate the incidence and type of sexual dysfunction and changes in serum concentration of sex hormones in male patients undergoing on-pump cabg...

BACKGROUND Postoperative atrial fibrillation (AF) is one of the most common complications after cardiothoracic surgery and is associated with an increased risk of stroke, and longer hospital stay. The pathophysiology of postoperative AF is uncertain, and its prevention remains unsatisfactory. Many previous studies have examined the predictors of AF after on-pump coronary artery bypass graft sur...

BACKGROUND On-pump coronary artery bypass graft (CABG) surgery impairs gas exchange in the early postoperative period. The main object on this study was evaluation of changes in arterial blood gas values in patients underwent on pump CABG surgery receiving different dose of intravenous nitroglycerin (NTG). MATERIALS AND METHODS sixty-seven consecutive patients undergoing elective on-pump CABG...
