Revascularization for coronary artery disease: stents versus bypass surgery.
Coronary artery disease (CAD) is one manifestation of ischemic heart disease, which is the leading cause of mortality in the world. In addition to preventive medical therapy and lifestyle changes, consideration of revascularization of obstructed arteries to reduce ischemia, alleviate angina, and improve quality of life is a mainstay of current practice. However, the benefits of different methods of revascularization in particular patient populations are debated. Percutaneous coronary intervention (PCI), which involves placement of intracoronary stents in most patients, is a less invasive procedure than coronary artery bypass graft (CABG) surgery. Although it is generally accepted that patients with single-vessel obstructive CAD are best treated with PCI, patients with multivessel CAD have a higher ischemia burden, a greater risk for developing recurrent ischemic events, and a higher mortality. It is in this patient population where the debate over revascularization with stents versus surgery continues.
