Introduction: The development of ischemic mitral regurgitation (IMR) after myocardial infarction (MI) may impose hemodynamic load during a period of active left ventricular remodeling and promote heart failure (HF). The aim of our study was to evaluate left ventricular (LV) long axis contraction assessed by both mitral annular plane systolic excursion (MAPSE) and peak systolic velocity (Sa) in patients with ischemic MR after acute MI. Methods: Thirty-eight patients with a first attack of acute MI were classified into two groups. Group I comprised 18 patients with MI and ischemic MR, and group II comprised 20 patients with MI without IMR. Twenty age-matched subjects were considered as the control group (group III). Measurement of MAPSE from M-mode tracing of the mitral annulus in apical 4- and 2-chamber view, and pulsed wave tissue Doppler imaging (PW-TDI) of the 4 sides of the mitral annulus for assessment of the Sa velocity were done. Results: A significant decrease of MAPSE was observed in 4 sides in patients with acute MI with IMR compared to MI without IMR and control group (P |
