NCT00999089

Last verified: October 2009
  Purpose
The individual contribution of the specific injuring mechanisms surgical trauma, extracorporeal circulation, and ischemia/reperfusion to clinical outcome in coronary revascularisation remains to be elucidated. The effect of these factors is analyzed in this randomized clinical trial by comparing the 3 surgical approaches: Conventional Coronary Artery Bypass Grafting (CCAB), with extracorporeal circulation and cardioplegic arrest; Off-Pump Coronary Artery Bypass Grafting (OPCAB), avoids extracorporeal circulation and global myocardial ischemia; and Pump-Assisted Coronary Artery Bypass Grafting (PACAB), with an unloaded and beating heart. The hypothesis addressed by the study is that the surgical invasiveness increases in the order: OPCAB, PACAB, CCAB.
