Frequency Of Mitral Regurgitation In Different Myocardial Infarction Patient Reported To Rmi Peshawar

Abstract

Background: Acute myocardial infarction (MI) has a significant impact on health-related quality of life and remains a leading cause of morbidity and mortality worldwide. It is a major contributor to the global burden of cardiovascular disease. Mitral regurgitation (MR) is a common mechanical complication of MI that adversely affects left ventricular function and contributes to the development of heart failure.

Objective: To determine the frequency of mitral regurgitation among patients with different types of myocardial infarction and to assess the severity of mitral regurgitation in these patients.

Methodology: Ethical approval was obtained from the Ethical Research Committee of Rehman College of Allied Health Sciences. An observational cross-sectional study was conducted involving 349 patients with myocardial infarction. Data were collected using a structured questionnaire, and the presence and severity of mitral regurgitation were assessed by echocardiography.

Results: A total of 349 patients were included in the study, comprising 240 (68.8%) males and 109 (31.2%) females. The frequency of mitral regurgitation was highest in patients with inferior myocardial infarction (58.16%), followed by anterior myocardial infarction (33.52%), posterior myocardial infarction (4.58%), and lateral myocardial infarction (3.72%). Mild mitral regurgitation was the most common grade observed across all types of myocardial infarction.

Conclusion: Mitral regurgitation was most frequently observed in patients with inferior myocardial infarction. Mild mitral regurgitation was the predominant grade among patients with all types of myocardial infarction, highlighting the importance of routine echocardiographic evaluation following acute myocardial infarction.
