BACKGROUND In patients with Acute Coronary Syndrome, correlation of ischemic ECG abnormalities with the affected coronary territory has not been well-established. We sought to investigate the correlation of electrocardiographic abnormalities with the location of obstructive coronary artery disease (CAD) confirmed by CAG, in patients with Acute Coronary Syndrome. MATERIALS AND METHODS In this study, 50 patients of Acute Coronary Syndrome were included. ECGs were interpreted by cardiologist. Patients were subjected to tread-mill test and Troponin T analysis whenever required. All patients underwent Coronary angiogram. The results of Coronary Angiogram were correlated with electrocardiographic findings, in terms of identifying the culprit vessel and severity of MI. RESULTS We noticed that there was significant correlation between coronary anatomy and electrocardiographic finding in STEMI involving anterolateral wall and inferior wall. In rest of the Acute Coronary Syndromes like NSTEMI and LBBB, there was no significant correlation. Normal electrocardiograms were also found to be associated with significant coronary artery disease. CONCLUSION Coronary angiogram is the gold standard to study the complete coronary anatomy. It helps in initiating appropriate management for CAD if any. Electrocardiogram acts just like an initial tool in guiding the management. For further appropriate management it has to be followed by coronary angiogram.
