BACKGROUND AND PURPOSE Early postoperative stroke is a serious adverse event after coronary artery bypass grafting (CABG). This study sought to investigate risk factors, prevalence, and prognostic implications of postoperative stroke in patients undergoing CABG. METHODS We investigated the predictors of postoperative stroke (n=333, 2%) in 16 528(More)
BACKGROUND Intercessory prayer is widely believed to influence recovery from illness, but claims of benefits are not supported by well-controlled clinical trials. Prior studies have not addressed whether prayer itself or knowledge/certainty that prayer is being provided may influence outcome. We evaluated whether (1) receiving intercessory prayer or (2)(More)
AIMS Thrombotic complications after percutaneous coronary intervention procedures have decreased in past years mainly due to the use of clopidogrel antiplatelet therapy. However, the risk of bleeding due to enhanced and irreversible platelet inhibition in patients who will require surgical coronary revascularization instead has not been adequately addressed(More)
Postoperative vasoplegic syndrome (PVS) is a frequent complication and can affect the early postoperative course. Our study investigated the incidence and risk factors of PVS after on-pump isolated coronary artery grafting bypass (CABG) and on-pump open-heart surgery. A total of 629 patients underwent on-pump cardiac surgery from November 21, 2005, to June(More)
BACKGROUND Postoperative stroke is a serious complication after coronary artery bypass grafting with cardiopulmonary bypass (on-pump), and portends higher morbidity and mortality. It is unknown whether an off-pump cardiopulmonary bypass (OPCAB) approach may yield a lower stroke rate over conventional on-pump coronary artery bypass grafting. METHODS From(More)
OBJECTIVE Postoperative vasoplegic syndrome (PVS) is a potentially lethal condition with increased mortality and other postoperative morbidities. Many previous studies have examined the outcomes associated with on-pump coronary artery bypass grafting (CABG) surgery, little is known about the incidence of PVS after off-pump CABG. METHODS From November 21,(More)
OBJECTIVE For patients who undergo off-pump coronary artery bypass (OPCAB) surgery, pulmonary artery catheterization (PAC) has been proposed as a useful intraoperative monitoring tool. This study was designed to determine if the choice of PAC versus central venous pressure monitoring (CVP) had any effect on outcome after OPCAB. This study compared these 2(More)
The appearance of cognitive dysfunction after cardiac surgery in the absence of focal neurologic signs, a poorly understood but potentially devastating complication, almost certainly results from procedure-related brain injury. Confirmation of the occurrence of perioperative silent brain injury has been developed through advances in magnetic resonance(More)
BACKGROUND Advances in coronary artery bypass grafting (CABG) surgery and percutaneous coronary intervention (PCI) with drug-eluting stents have dramatically improved results of these procedures. The optimal treatment for patients with multivessel coronary artery disease is uncertain given the lack of prospective, randomized data reflecting current(More)
BACKGROUND Cerebral embolization of atherosclerotic plaque debris caused by aortic manipulation during conventional coronary artery bypass grafting (CABG) is a major mechanism of postoperative cerebrovascular accidents (CVA). Off-pump CABG (OPCABG) reduces stroke rates by minimizing aortic manipulation. Consequently, the effect of different levels of aortic(More)
