Abstract:
:A total of 1,275 elderly patients (70 years and older) underwent coronary artery bypass alone from 1970 to 1981. The percent of elderly patients who underwent coronary bypass surgery alone increased from 2.04% in 1971 to 8.2% in 1981. Most of the patients had severe, disabling or unstable angina pectoris. The overall early mortality rate was 5.8%. The early mortality rate was 13.9% in the first group (1970 to 1975) of 158 patients compared with 4.7% in the second group (1976 to 1981) of 1,117 patients. An average of 3.1 bypass grafts per patient were implanted. On follow-up examination, angina was relieved or decreased in 89% of the patients. The 5 year survival rate was 80.6% and the 10 year survival rate was 44.1%, with an average attrition of 3.9 and 5.6%/year, respectively. It is concluded that elderly patients are high risk surgical candidates, yet the risk has decreased progressively because of improved techniques of medical and surgical management and myocardial preservation. This decreasing operative mortality rate provides evidence that when medical management of the elderly patient with severe angina fails, coronary artery bypass becomes a successful alternative.
