Cardiac surgery in patients age 80 years or older.

Between February 1978 and August 1989, forty patients aged 80 years or older underwent cardiac surgery at this institution. Patient age varied from 80 to 87 years (mean, 82.4 years). Operative indications were angina pectoris or congestive heart failure. Twenty-eight patients underwent coronary artery bypass (CAB) alone and 12 underwent valve replacement(s) with or without CAB. The operative mortality rate was 10%. Postoperative hospitalization averaged 14 days. There were three late cardiac deaths at 13, 36, and 48 months after operation and one late noncardiac death. Thirty-two survivors have been followed from 1 to 86 months (mean, 20 months). All experienced sustained improvement in functional status and minimal late morbidity. All survivors remained in NYHA class 1 or 2. Cardiac surgical procedures in patients older than 80 years can be performed with increased but acceptable mortality and morbidity rates. Most patients achieve sustained symptomatic improvement and excellent long-term survival.
