Abstract
Left ventricular dysfunction and coronary artery disease has been defined as ischemic cardiomyopathy with specifically left ventricular ejection fraction less than 35% and coronary artery disease defined as angiographically 70% narrowing of one or more coronary arteries. There are two main steps in the evaluation of patients with left ventricular dysfunction in terms of determining the contribution of coronary disease and the possible role of revascularization. The detection of viable myocardium is of importance because the restoration of blood flow with revascularization can reverse depressed LV contractility, improve LV function, and reduce long-term mortality. Revascularization by Coronary artery bypass graft or percutaneous coronary intervention with stenting. Patients who have ischemic cardiomyopathy and viable myocardium benefit from revascularization, revascularization should be considered in patients with ischemic cardiomyopathy, there are improvement in survival , left ventricular dysfunction, and symptoms.
