Dobutamine Stress Echocardiography Is Highly Accurate for the Prediction of Contractile Reserve in the Early Postoperative Period, but May Underestimate Late Recovery in Contractile Reserve After Revascularization of the Hibernating Myocardium

Dobutamine stress echocardiography can predict early recovery in CR postrevascularization with an excellent accuracy but may underestimate the degree of late recovery in CR.
