2D Echocardiography with color Doppler assessment:~It will be done within 24 h after PPCI. Measurements will be as following:~Pulsed wave (PW) Doppler will be performed in the apical 4chamber view within a 3 mm sample volume at the tip of the mitral leaflets to obtain mitral inflow velocities to assess LV filling.~E (early diastolic)/A (late diastolic) - Using PW Doppler, the peak E and A velocities were recorded, then the ratio of E/A will be calculated.~IVRT (isovolumic relaxation time) - derived by placing the cursor of Continuous wave (CW) Doppler in the LV outflow tract to simultaneously display the end of aortic ejection and the onset of mitral inflow.~Deceleration time (DT) - from the peak of E wave to baseline.~E/e'- PW tissue Doppler imaging (TDI) was performed in the apical views to acquire mitral annular velocities. The sample volume will be positioned at or 1 cm within the mitral leaflet's septal and lateral insertion sites.~Left atrial volume and left atrial volume index (LAVI) - The maximal left atrial (LA) volume measured from the apical four-chamber view using the modified Simpson method in end-systole before mitral valve opening. The LAVI obtained for all patients by dividing the LA volume by the body surface area.~Biochemical measurements:~Peripheral blood samples were obtained within 48 hours after acute MI, and the serum will be frozen at -70°C until tested for Galactin-3 level.~Follow up 2D Doppler echocardiography:~All previous echocardiographic measurements will be repeated at 40 days of the event.
