Comparison of Myocardial Contrast Echocardiography and Low-Dose Dobutamine Stress Echocardiography in Predicting Recovery of Left Ventricular Function After Coronary Revascularization in Chronic Ischemic Heart Disease

Abstract

Both contractile reserve by DSE and perfusion by MCE are predictive of functional recovery in hypokinetic segments after coronary revascularization in patients with chronic coronary revascularization in patients with chronic coronary artery disease. In akinetic segments, myocardial perfusion by MCE may exist in segments that do not recover contractile function after revascularization. Thus, contractile reserve during low-dose dobutamine infusion is a better predictor of functional recovery after revascularization in akinetic segments than perfusion.
