Surgical versus percutaneous revascularization of coronary artery disease in diabetic patients

Morbidity and mortality related to coronary artery disease (CAD) remain a great challenge in patients with diabetes mellitus. Revascularization of CAD is an important therapeutic intervention owing to its impact on both symptoms and prognosis. The optimal revascularization strategy continues to evolve due to the advent of new technologies and improved peri-procedural outcome with both percutaneous coronary interventions and coronary artery bypass grafting. Although clinical outcome following coronary artery bypass is worse in diabetic as opposed to non-diabetic patients, Surgical revascularization tends to be associated with better Outcome ill stable patients with multivessel disease and reduced left ventricular function. The advent of drug-eluting stents has challenged the supremacy of coronary artery bypass grafting and has become a valuable alternative to Surgery. The safety and efficacy of drug-eluting stents in the treatment of patients with diabetes and multivessel disease is currently under investigation in several ongoing randomized controlled trials. Percutaneous coronary intervention is the therapy of choice in patients with acute coronary syndromes, particularly ST-elevation myocardial infarction. The focus of this review is to present the current evidence, define the role of percutaneous and surgical revascularization in the treatment of diabetic patients with CAD, and propose a tailored approach for clinical decision-making.
