Death, mode of death, morbidity and requirement for rehospitalization during 2 years after coronary artery bypass grafting in relation to preoperative ejection fraction.
OBJECTIVE: To describe the impact of ejection fraction on the prognosis during 2 years after coronary artery bypass grafting (CABG). PATIENTS: All patients in western Sweden who underwent CABG without concomitant valve surgery between June 1988 and June 1991. RESULTS: In all, 2121 patients were operated upon and information on ejection fraction was available for 1961 patients (92%). Of these patients, 178 (9%) had an ejection fraction or = 60%. In these groups the mortalities during the first 30 days after CABG were 5.1, 4.3 and 2.2%, respectively (P
