Coronary artery bypass surgery in women.

Coronary bypass surgery is performed more frequently in men than in women. A selection bias in favor of men may exist in currently utilized evaluation precesses for patients with both chest pain syndromes and documented coronary artery disease. Surgery should be considered in women with significant left main coronary artery stenosis, "left main equivalent" coronary disease, severe three-vessel coronary disease with/without left ventricular dysfunction, two-vessel coronary disease (including a proximal left anterior descending artery stenosis), and unstable angina pectoris with decreased left ventricular function. Women and men undergoing coronary bypass surgery seem to benefit from internal mammary artery grafts used alone or in combination with saphenous vein grafts. Surgical mortality, incomplete revascularization, early and late graft occlusion, and recurrent angina are more prevalent in women who undergo surgery. However, long-term mortality following surgery is similar in men and women.
