Abstract :

Myocardial infarction is a clinical state occurring as a consequence of imbalance between myocardial oxygen supply versus demand; leading to ischemic necrosis of myocardium. To know the prognosis and clinical state, left ventricular function assessment is important. Past 3–4 decades has witnessed enormous growth in understanding the pathophysiology as well as recent laboratory facilities, both invasive and noninvasive, which yields, better data regarding mortality and morbidity in acute or long term prognosis. There are various invasive and noninvasive imaging techniques, out of which echocardiography of the heart is the gold standard in accurate prediction of left ventricular function, both global and regional Doppler is an another invaluable tool to measure flow rate, peak velocity of red blood cells resolution for regurgitation flow. This study was undertaken to highlight the echocardiographic evaluation of left ventricular function, mainly stroke volume and ejection fraction and estimation of troponin levels in patients with acute MI, studied at the time of discharge.
