OBJECTIVES This study evaluates the effect of pre-operative angiotensin-converting enzyme inhibitor (ACEI) therapy on early clinical outcomes after coronary artery bypass grafting (CABG). BACKGROUND Therapy with ACEIs has been shown to reduce the rate of mortality and prevent cardiovascular events in patients with coronary artery disease. However, their(More)
BACKGROUND Patients presenting with severe left ventricular (LV) dysfunction undergoing coronary artery surgery are at increased risk of perioperative morbidity and mortality. The present study investigated early and midterm outcomes in a consecutive series of patients with severe LV dysfunction undergoing coronary surgery at our institution. METHODS Data(More)
BACKGROUND Postoperative atrial fibrillation is still a common complication in patients undergoing coronary artery bypass grafting. The aim of this study was to evaluate the effect of preoperative statin therapy on new onset of postoperative atrial fibrillation in patients undergoing coronary artery bypass grafting. METHODS Of 8,946 patients undergoing(More)
BACKGROUND Although there is growing evidence to suggest that the administration of magnesium (Mg2+) to patients undergoing coronary artery bypass grafting (CABG) and to patients after myocardial infarction is beneficial, the addition of Mg2+ to cardioplegic solutions remains controversial. The aim of this study was to compare the effects of intermittent(More)
OBJECTIVE To assess the safety and efficacy of on-pump beating heart coronary surgery on organ function, and early and late health outcome as compared with conventional technique. METHODS A total of 81 patients were randomised to (1) coronary surgery with cardiopulmonary bypass (CPB) and cardioplegic arrest (CA) (on-pump with CA, n=41) or to (2) CPB(More)
AIM A variety of chest radiograph abnormalities are recognized after coronary artery bypass grafting (CABG). This study analyzes the appearance of preoperative and postoperative chest radiographs in two groups of patients undergoing myocardial revascularization with or without the use of cardiopulmonary bypass (CPB). METHODS Chest radiographs(More)
Penetrating trauma to the chest leading to coronary artery injury is associated with a high mortality rate, especially in the case of injury to the left anterior descending (LAD) coronary artery. The mortality rate remains high whether they are managed with primary ligation or with coronary artery bypass grafting using conventional cardiopulmonary bypass(More)
Malignant degeneration of neurogenic tumors has been reported to occur in 1-25% of patients with neurofibromatosis-I, and is the leading cause of cancer-related death in these patients. We report a case of multidisciplinary management of a giant malignant endothoracic nerve sheath tumor leading to histologically proven remission.
BACKGROUND This study investigated the hemodynamic changes in patients undergoing multiple vessel beating heart coronary revascularization in the presence or absence of an intracoronary shunt. METHODS Forty patients were randomized to off-pump with a shunt (n = 20) or with the proximal coronary artery occluded by a soft snare (n = 20). Hemodynamic(More)
