PURPOSE: Cardiac surgery and conventional extracorporeal circulation (CECC) impair the bioavailability of drugs administered by mouth. It is not known whether miniaturized ECC (MECC) or off-pump surgery (OPCAB) affect the bioavailability in similar manner. We evaluated the metoprolol bioavailability in patients undergoing CABG surgery with CECC, MECC, or having OPCAB. METHODS: Thirty patients, ten in each group, aged 44-79 years, scheduled for CABG surgery were administered 50 mg metoprolol by mouth on the preoperative day at 8-10 a...

Paraplegia is an exceedingly rare neurologic complication after off-pump coronary artery bypass graft (OPCAB) surgery commonly caused by spinal cord ischemia (SCI). SCI is not a well unknown clinical phenomenon in the postoperative course. SCI has been reported after noncardiac surgery in otherwise healthy subjects in whom only one risks factor i.e. severe hypotension has been documented. SCI has also been reported as a rare complication among the other neurologic sequels of cardiac surgery. We report a case of paraplegia in a patient with metabolic syndrome and multiples risk factors after an OPCAB...

Hyper-coagulation after off-pump coronary artery bypass grafting (OPCAB) is one of the main reasons for graft thrombosis. D-dimer is closely linked to the activation of coagulation. Few studies have reported the variation range and long-term abnormal coagulation after OPCAB in the Chinese population. Our study aimed to determine the characteristics and value of D-dimer after OPCAB.In this prospective study, 265 patients who underwent OPCAB for the first time were recruited from 2011 to 2012. The D-dimer level of the patients was tested before surgery and on the 1st, 4th, and 14th day, and 1st, 2nd, and 3rd month after surgery...

We aimed to evaluate the timing of preoperative intra-aortic balloon pump (IABP) placement and outcomes in patients undergoing off-pump coronary artery bypass grafting (OPCAB). Patients with prophylactic IABP placement before OPCAB presenting between January 1, 2010 and December 31, 2013 were included. Patients were categorized into two groups based on the timing of preoperative IABP placement: less than 2 h (Group A, n = 223) and more than 2 h (Group B, n = 94). According to the European System for Cardiac Operative Risk Evaluation (EuroSCORE), patients were divided into two subgroups: middle-low EuroSCORE (<6, Groups A1 and B1) and high EuroSCORE (≥6, Groups A2 and B2)...

BACKGROUND: Cardiac surgery often causes ischemia and development of a systemic inflammatory response syndrome, which impairs vascular barrier function, normally maintained by the endothelial cell line and the endothelial glycocalyx (EG). The EG normally covers and protects healthy endothelial cells throughout the vasculature. The aim of the present study was to assess the disruption of the cellular part of the microvascular barrier by determining parameters of endothelial cell activation known to influence and reflect cell-cell junctional integrity...
