Mid- and long-term prognosis of off- vs. on-pump coronary artery bypass graft in patients with multisite artery disease.

Abstract : Among patients with coronary artery disease (CAD), around 25% have multisite artery disease (MSAD). Patients with CAD and MSAD are at higher risk of peri-operative and long-term cardiovascular events. Whether off-pump coronary bypass grafting (CABG) can improve their prognosis is unknown.We aimed to assess the benefits of off- vs. on-pump cardiac surgery in patients undergoing CABG, according to coexistence of extra-cardiac artery disease.
