Improving results for coronary artery bypass graft surgery in the elderly
B Yanagawa, KD Algarni, TM Yau... - ... Journal of Cardio- ..., 2012 - ... Trends in coronary artery bypass surgery results: a recent, 9-year study. ... Five-year outcomes after
coronary stenting versus bypass surgery for the treatment of multivessel disease: the final analysis
of the Arterial Revascularization Therapies Study (ARTS) randomized trial. ...
RESULTS Overall mortality declined from 6.0% (49/817) in the earliest era (1990–96) to 1.9% (22/1132) in the most recent era (2003–10; P < 0.001). Mortality in low-risk patients (elective, primary surgery with the ejection fraction >40%) was 5.9% (13/220), 0.8% (4/514) and 0% (0/411) in the first, second and third eras, respectively (P < 0.001). Despite the overall increase in comorbidities in our elderly patients, the prevalences of certain risk factors such as poor LV function, urgency of surgery and reoperation have all declined with time. The independent risk factors for mortality in our population were congestive heart failure, left main disease, earlier year of operation, reoperation, preoperative myocardial infarction, cardiopulmonary bypass time, emergent/urgent surgery and peripheral vascular disease. Of these, earlier year of operation (OR: 3.0; 95% CI: 1.8–5.2) was the most significant predictor. Also, age >80 did not predict mortality.
