Myocardial Performance Index as a predictor of Angiographic Severity of Coronary Artery Disease in patients with Acute Myocardial Infarction.

CONCLUSION : The following conclusions were derived from our study Myocardial performance index is significantly higher in anterior infarcts than in Inferior infarct patients. Myocardial performance index has got a good correlation with systolic as well as diastolic function parameters. While Myocardial performance index was found to have a significant inverse relationship with Ejection fraction, it was also found to have significant relationship with abnormalities in diastolic function parameters like Deceleration time, Isovolumic relaxation time and E/E’ ratio. Myocardial performance index has got a significant positive correlation with Killip class. Myocardial performance index is significantly increased in patients with proximal LAD, proximal RCA lesions compared to distal lesions. Myocardial performance index is significantly elevated in Double Vessel Disease and Triple Vessel Disease compared to Single Vessel Disease
