Coronary artery bypass

In medicine, coronary artery bypass is a form of myocardial revascularization that is a "surgical therapy of ischemic coronary artery disease achieved by grafting a section of saphenous vein, internal mammary artery, or other substitute between the aorta and the obstructed coronary artery distal to the obstructive lesion.'

Patient who have a left ventricular ejection fraction between 35 and 49 percent benefit from coronary artery bypass surgery if they have disease of three coronary arteries. .

Coronary artery bypass is more effective than angioplasty for myocardial revascularization of coronary heart disease, especially for patients with diabetes who have stenosis of three coronary arteries. Angioplasty did not include stents in this study.
