One of the important complications which causes the increase of mortality and economic burden on patient is the ischemic MR. Its main pathophysiology is the remodeling of the LV after MI which causes the hemodynamic load and heart failure. However, the data on relationship between ischemic MR and duration of heart failure is very few. We prospectively studied 300 patients who admitted for acute myocardial infarction in our hospital. All patients were assessed by echocardiography and graded MR as mild, moderate, and severe according to regurgitant jet area which is less than 20%, 20 – 40%, and more than 40% of the left atrial area, respectively. The median duration of follow up was 1 year (range 6-12 months). Mild and moderate or severe ischemic MR was present in 40.2 and 6.4% of patients respectively. The hazard ratios for HF were 2.9 (95% condence interval (CI), 1.9–4.3; P |
