Abstract

BACKGROUND: Myocardial Infarction was described as acute onset chest pain attributed to the event of Coronary Thrombosis. A subset of it is Right ventricular Myocardial Infarction (RVMI) which is underdiagnosed in most instances despite its close association with Inferior wall Myocardial Infarction (IWMI). This study aims to assess any specific risk factors, ECG changes and variation in biomarkers for RVMI in a case of IWMI. METHODS: An observational cross-sectional prospective study wherein 104 IWMI patients being admitted to MGMGH, Trichy were taken up and the prevalence of RVMI, risk factors, occurrence of arrhythmias and changes in biomarker levels have been studied. RESULTS: 25% of the 104 patients studied had RVMI coexisting with IWMI. Smoking and Alcoholism were not found to be statistically significant risk factors for RVMI in IWMI with a chi square statistic of 1.93 and 2.97 respectively (both p values 0.164 more than 0.05). The incidence of arrhythmias in RVMI with IWMI is statistically significantly different from that of isolated IWMI with Fischer exact statistic test value 0.00001(p<0.05). The change in biomarker CK-MB level in RVMI with IWMI is statistically significantly different from that in isolated IWMI with an unpaired student t-test value p < 0.05. CONCLUSION: One in every fourth patient presenting with acute IWMI had right ventricular Involvement. The mean serum CK-MB level and the incidence of arrhythmias are Significantly higher in the subset of population with RV involvement than those without RV involvement in a case of inferior wall MI.
