Abstract

To compare the results of coronary artery bypass in women and men, we reviewed our experience from January 1976 through June 1989. During this period, 170 women with coronary artery disease but with no other cardiac abnormalities underwent coronary artery bypass. We compared this group with a group of 150 men, matching them according to age, presence of angina, extent of disease, and surgical treatment. Preoperative clinical features, surgical data, and early and late results were analyzed. The operative mortality was similar between groups (2.9% for women vs 2.6% for men). The women, however, were more frequently overweight (54% vs 15%; p <0.001) and more often had the following: diabetes mellitus (34% vs 20%; p <0.01), a coronary artery diameter of <1.8 mm (64% vs 29%; p <0.001), poor saphenous vein quality (50% vs 16%; p <0.001), and incomplete revascularization (20% vs 4%; p <0.001). After a mean follow-up of 6 years, the women also had a higher incidence of recent-onset myocardial infarction (31% vs 12%; p <0.001) and a greater tendency to be symptomatic (48% vs 19%; p <0.001). The 12-year cumulative survival rates were similar in both groups (76.2% for women vs 77.1% for men). According to logistic regression analysis of the significantly different variables, the only independent determinants of postoperative asymptomatic status were satisfactory coronary artery caliber, good saphenous vein quality, and complete revascularization. We conclude that poorer functional results after coronary artery bypass surgery in women may be caused by a poorer quality of revascularization, which in turn is a result of smaller coronary artery diameter, worse distal runoff, and less satisfactory vein quality.
