BACKGROUND Myocardial contractile reserve has been shown to provide important prognostic information in patients with heart failure. We hypothesized that myocardial contractile reserve would predict left ventricular (LV) reverse remodeling after cardiac resynchronization therapy (CRT). METHODS Thirty-one consecutive patients with heart failure (LV ejection fraction [LVEF] 26% +/- 7%, 35% nonischemic cardiomyopathy) underwent echocardiography during low-dose dobutamine infusion before CRT… CONTINUE READING
