Coronary artery bypass in patients over 70 years of age: indications and results.
With recent advances in all phases of coronary care and the increasing success of coronary arterial surgery, operative treatment of coronary artery disease is more readily recommended, even for patients over 70 years of age. In a series of 3,730 patients who underwent aortocoronary bypass from November 1969 through June 1974, there were 95 patients who were 70 years of age or older. The primary indication for surgery was severe angina, which was present in 88 patients. The mean coronary arterial score was 9.51. Associated valvular lesions were treated surgically in 21 patients, and a left ventricular aneurysm was resected in 7. Improvements in surgical technique and postoperative care are responsible for the hospital mortality rate of only 4.8 percent in the 21 patients operated upon during the first 6 months of 1974 compared with the overall mortality rate of 22.1 percent in all 95 patients. Long-term follow-up among the 95 patients includes data from 33 patients: 9 patients whose condition improved, 21 who were asymptomatic and 1 "coronary death".
