Objective: In this study our main goal is to early detection of multivessel disease and prevention of short and long term complications. Methods: This was prospective and observational study conducted at National Institute of Cardiovascular Diseases, Shere-e-Bangla Nagar, Dhaka, Bangladesh from February 2012 to December 2012. We examined enlisted eighty four (n=84) consecutive patients with acute inferior myocardial infarction within 12 hours of onset of chest pain and underwent thrombolysis in coronary care unit. Consequently patients were classified in two groups on the basis of admission electrocardiogram. Group A patients with acute inferior myocardial infarction associated significant (≥ 0.1 mV) precordial ST segment depression in leads V1-V6 (n=44, 52.38%); whereas group B had no remarkable precordial ST segment change (n=40, 47.62%). Thereafter Echocardiography was recorded within 3rd day and catheterization with coronary angiography was done within 4 weeks of infarction. Result: Angiographic result was in patients with precordial ST depression had more prevalence to double vessel (77.3% vs. 22.5%) and triple vessels disease found to be higher in group A (15.9% vs. 2.5%). Though anterior descending artery involvement was higher than left circumflex, but independent left anterior descending lesion could not implicated. Conclusion: In overall outcome, patients with ST segment depression in acute inferior myocardial infarction liked with more wideness of ischemic area of infracted zone and more prevalence to multi vessel lesion (double or triple vessel) and index of worse prediction. In conclusion, the current study may give significant clinical benefit to prediction of coronary artery involve from admission ECG, concurrently
