Does myocardial contrast echocardiography compare favorably to low-dose dobutamine stress echocardiography in predicting recovery of left ventricular function after coronary revascularization in patients with chronic ischemic heart disease?
Low-dose dobutamine stress echocardiography is a better predictor of functional recovery after revascularization in akinetic segments than myocardial contrast echocardiography due to higher specificity and positive predictive value.
