Cardiac resynchronization therapy (CRT) reduces functional mitral regurgitation (MR) at rest. This study assessed exercise-induced changes in MR in patients with heart failure who were helped by CRT. The determinants of these exercise-induced changes in MR were analyzed in asynchronous and resynchronized left ventricles.
Aims To assess the accuracy of positron emission tomogra-phy to predict recovery of global cardiac function after revascularization in patients with coronary artery disease. Methods and Results One hundred and seventy-eight patients (157 male, 5810 years) with coronary artery disease and left ventricular dysfunction (mean ejection fraction 3914%) were(More)
BACKGROUND Cardiac resynchronization therapy (CRT) provides benefit for congestive heart failure, but still 30% of patients failed to respond to such therapy. This lack of response may be due to the presence of significant amount of scar or fibrotic tissue at myocardial level. This study sought to investigate the potential impact of myocardial contractile(More)
