background according to the previous studies, antihypertensive drugs should be withdrawn before surgery.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...

A concept of bypass rewiring is introduced, and random bypass rewiring is analytically and numerically investigated with simulations. Our results show that bypass rewiring makes networks robust against removal of nodes including random failures and attacks. In particular, random bypass rewiring connects all nodes except the removed nodes on an even degree infinite network and makes the percolat...

Background : Quests for doing coronary artery bypass surgery by a technique with lower complications is going on, for this aim many studies compared patients undergoing CABG with or without cardiopulmonary bypass. This study was carried out to compare laboratory findings after coronary artery bypass in these two groups of patients. Materials and Methods: In a retrospective study, 167 patients ...
