Background: According to recent research, examining the ST-segment shift in lead aVR provides valuable information on coronary angiographic anatomy and risk categorization. In acute anterior wall myocardial infarction (MI), lead aVR has diagnostic and prognostic relevance. The purpose of this study is to look at the relationship between presenting clinical status and coronary artery disease risk factors and ST-segment deviation in lead aVR. Methods: This prospective observational hospital-based study was carried out in the Department of Cardiology at Batra Hospital and Medical Research Centre in New Delhi. Patients with acute anterior wall ST-elevation MI who presented within 24 h of symptoms were included in the study. Continuous data were expressed as mean standard deviation and categorical variables as the number or percentage of patients. Results: The study involved 73 individuals who met the inclusion and exclusion criteria and had acute anterior wall ST-elevation MI. Thirty of the 73 patients (41%) had ST-segment elevation in lead aVR larger than 0.5 mm. In two groups, the distribution of various cardiovascular risk factors was examined. In all of the cases, the left anterior descending artery was affected. Patients with double- and triple-vessel disease were seen in more significant numbers in Group A than in Group B. Cardiogenic shock occurred in 6 of 30 patients in Group A and 3 of 43 patients in Group B. Conclusions: ST-elevation in lead aVR has predictive value. Patients with higher ST-segment elevation in aVR are more likely to suffer angina, CHF, and cardiogenic shock complications. Providing these patients with percutaneous or surgical revascularization therapy as soon as possible can reduce mortality.
