Randomized Controlled Trial
Biocompatibility of heparin-coated cardiopulmonary bypass circuits in coronary patients with left ventricular dysfunction is superior to PMEA-coated circuits.
Several coating techniques for extracorporeal circulation have been developed to diminish the systemic inflammatory response during cardiopulmonary bypass (CPB). The aim of this study was to evaluate the clinical effectiveness and biocompatibility of heparin-coated and poly-2-methoxyethylacrylate (PMEA)-coated CPB circuits on coronary patients with left ventricular systolic dysfunction. ⋯ Heparin-coated circuit provided better suppression of perioperative inflammatory markers and exhibited more favorable effects on hematologic variables than PMEA-coated circuit.

Previous studies suggest that nonelective coronary artery bypass graft surgery (CABG) is more costly than elective CABG. The goal of this study was to examine why cost differences exist between patients undergoing nonelective and elective CABG. ⋯ Patients undergoing nonelective CABG have longer LOS and higher costs than patients undergoing elective CABG. The increased cost among nonelective patients is largely due to differences in rates of preoperative LOS, angiography, and PCI. This differential reflects increased nonsurgical costs among patients undergoing nonelective CABG rather than surgical costs.
