[Aortocoronary bypass surgery in patients older than 70 years].
From January 1981 to December 1990, 204 patients aged between 70 and 81 years underwent aortocoronary bypass surgery. Operative mortality (30-day mortality) was 6.8%. Actuarial survival rate at 1 and 5 years was 92% and 86% respectively. A higher incidence of postoperative complications was observed (arrhythmias in 19%, reoperation for bleeding in 5.4%, respiratory and neurological complications in 13% and 3% respectively, perioperative infarction in 4.4%). The mean follow-up was 25 months. Preoperatively most patients (71%) were in New York Heart Association (NYHA) functional class III and IV, and at the end of following-up in NYHA functional class I and II (95%) (p less than 0.001). A rapid rise in coronary artery surgery in the elderly is evident. It is associated with an increased but acceptable operative risk. Long-term results and postoperative improvement of functional status are very satisfactory.
