Abstract

Background: Approximately 30–50% of patients with inferior infarction have some involvement of the right ventricle. The right ventricular (RV) infarction almost invariably develops in association with a large infarction of the adjacent septum and inferior 0 walls, but isolated infarction of the right ventricle is seen in just 3–5% of autopsy-proven cases of MI. This study is designed to assess the right atrial (RA) functions in inferior wall acute myocardial infarction (AMI) (IWMI) echocardiographically and to compare it with patients who do not have history of ischemic heart disease (IHD) but having risk factors for IHD. 

Aims and Objectives: The aims of this study were to study the patients presenting with Inferior wall MI IWMI for RA function.

Materials and Methods: Patients admitted in the Cardiology ward of R G Kar Medical College and Hospital with IWMI from March 2020 to March 2022 were included in the study.

Results: Average Measurement of RA volume index (RAVI) and RA Pressure (RAP) was highest among patients with IWMI+RV myocardial infarction (RVMI). Out of 100 IWMI patients, 33 had high RAVI and RAP and out of 100 non-IHD patients none had high RAVI.

Conclusion: In our study, there was no statistically significant difference in average RAVI and RAP in patients presenting with IWMI and in patients with risk factors for myocardial infarction but without AMI. However, patients presented with IWMI+RVMI showed statistically significant increased RAVI and RAP as compared to inferior wall AMI only.
