AIMS Presence of contractile reserve during low-dose dobutamine stress echo (DSE) appears predictive of cardiac resynchronization therapy (CRT) outcome. We hypothesize that changes in left bundle branch block (LBBB)-induced dyssynchronous motion during low-dose DSE could be related to the extent of reverse remodelling. METHODS AND RESULTS Fifty-two patients (69 +/- 2 years, EF: 24 +/- 7%, QRS > 120 ms) were studied pre- and post-CRT (7 +/- 1 months). Reduction in left ventricular end-systolic… CONTINUE READING
