Treatment of severe coronary artery disease with 5, 6, and 7 saphenous vein bypasses: review of 131 consecutive patients
GF Geisler, M Adam, BF Mitchel, CJ Lambert and JP Thiele
One hundred thirty-one consecutive patients who received 5, 6, and 7 bypass
grafts are analyzed. Ages ranged from 31 to 74 years. The male- to-female
ratio was 7:1. As an indication of severity of disease, 25% were classified
as having impending myocardial infarction and 46.6% were classified in New
York Heart Association Functional Class IV. Left ventricular function was
impaired in 37.4%, and 30% of the patients had left main coronary
obstruction. Nonfatal perioperative myocardial infarction occurred in 4.6%.
The hospital mortality was 3%. One hundred percent follow-up (5 to 55
months) revealed 4 late deaths, 3 presumably of cardiac origin. Only 7
patients in the postoperative follow-up group have complained of angina; 1
has since undergone successful reoperation.
