BACKGROUND/AIMS: Mitral regurgitation (MR) following myocardial infarction (MI) may be a (sub)acute complication which independently predicts reduced survival. We sought to evaluate the chronic development of MR as potential consequence of left-ventricular (LV) remodelling, the latter being a long-term process. METHODS AND RESULTS: Retrospectively, 103 post-MI patients were included according ...
