"Unveiling Right Ventricular Dysfunction in Inferior Wall Myocardial Infarction: Echocardiographic Insights and Angiographic Correlation with Right Coronary Artery Stenosis".

Acute coronary syndrome (ACS), including acute myocardial infarction (MI) and unstable angina, is characterized by ischemia due to plaque instability, thrombosis, and vasospasm. Right ventricular (RV) infarction, commonly seen in inferior wall MI (IWMI), worsens prognosis with increased risk of complications. While proximal right coronary artery (RCA) occlusion is the primary cause of RV infarction, some distal occlusions also result in RV dysfunction. This study evaluates if echocardiographic RV function parameters can predict proximal RCA stenosis in IWMI patients. In this prospective study, 60 IWMI patients were divided into two groups based on coronary angiography: Group A (35 with proximal RCA stenosis) and Group B (25 with distal RCA stenosis). Echocardiographic parameters, including TAPSE, RVFAC, MPI, and Sm, were measured within 24 hours of symptom onset. Results showed significantly lower RVFAC and TAPSE, and higher MPI, in the proximal RCA stenosis group. Echocardiography effectively identified proximal RCA stenosis, offering valuable insights for improved patient management and outcomes. [ABSTRACT FROM AUTHOR]
