Treatment of diabetic patients with multivessel coronary artery disease is controversial. This paper reviews pertinent literature on surgical revascularization with emphasis on which patients benefit from therapy. Recent studies of medical, percutaneous, and surgical therapies have added greatly to our understanding of the treatment of diabetic patients with coronary artery disease. Randomized trials show no advantage with prophylactic percutaneous coronary intervention over medical therapy. However, in patients with more severe three-vessel disease, coronary artery bypass graft surgery (CABG) improved outcomes with respect to reduced myocardial infarction events and cardiac death as compared with medical therapy. In addition, rates of late myocardial infarction and mortality were significantly lower in patients treated with CABG compared with those who received drug-eluting stents. Although the need for subsequent revascularization with drug-eluting stents is reduced compared with angioplasty and bare-metal stents, the rate is still higher than that associated with CABG. CABG reduces risks of myocardial infarction, cardiac death, and need for repeat revascularization in diabetic patients with severe, multivessel coronary artery disease.
