title: [Morbidity and mortality of coronary artery bypass surgery in patients 75 years of age or older].
abstract: A consecutive series of 30 patients 75 years of age and older who underwent isolated coronary artery bypass graftings during a 6 year period (from 1985 to 1990) was analyzed. This group was compared with a consecutive series of 512 patients under the age of 75 who underwent the same procedure during the same period. The elderly patients had a higher incidence of unstable angina pectoris, left main or triple vessel disease and depression of ejection fraction. There were no deaths in the hospital or within 30 days of operation (0%), but postoperative complication occurred in 26 cases (86.7%) in the elderly patients. Mean postoperative hospital stay was longer in the elderly patients than the younger ones (21.7 +/- 8.7 days, 18.9 +/- 5.9 days, respectively). The factors frequently noted in the elderly cases with major complications were emergency or urgent operation, history of congestive heart failure and diabetes. The factors associated with prolonged postoperative hospital stay in elderly cases were octogenarians, intraoperative blood transfusion, wound complications, perioperative myocardial infarction, pulmonary failure and low cardiac output state. It is concluded that CABG can be performed safely even in elderly patients by the proper postoperative management, in spite of having increased postoperative complications and resulting in a prolonged postoperative hospital stay.
