Outcomes of cardiac surgery in senior aged patients with ventricular dysfunction: analysis of a large national database

摘要

In patients undergoing cardiac surgery, reduced preoperative ejection fraction (EF) and senior age are associated with a worse outcome. As most outcome data available for these patients are mainly from Western surgical populations involving specific surgery types, our aim is to evaluate the real-world characteristics and perioperative outcomes of surgery in senior-aged heart failure patients with reduced EF across a broad range cardiac surgeries.
