FREQUENCY OF RIGHT VENTRICULAR INFARCTION IN PATIENTS WITH INFERIOR WALL MYOCARDIAL INFARCTION

Abstract

Objective: To determine frequency of Right ventricular infarction in patients of inferior wall myocardial Infarction at cardiology department of various hospitals in Karachi.

METHODS: This multicenter cross sectional study was conducted in cardiology department of different hospitals in Karachi from 01/01/2016 to 31/12/2017 for a period of 02 years.A total of 303 patients who suffered from inferior wall myocardial infarction admitted to the hospitals included Abbasi Shaheed Hospital, Karachi Institute of Heart Diseases, National Institute of Cardiovascular Diseases and Civil Hospital Karachi were enrolled. All the study patients were analyzed primarily for the frequency of right ventricular myocardial infarction (RVMI) and secondarily associated risk factors like age, gender, hypertension, diabetes, smoking, chest pain and family history. A predesigned questionnaire used to collect data and the data was analyzed statistically. RESULTS: The results of this study shows that the patients diagnosed with acute inferior wall myocardial infarction found to have n=94 (31.039o) frequency of developing right ventricular infarction, There were n=225 male patients (74.259c) and 78 female patients (25.759c). The mean age of the patients was 55.7 + 12.9 and within this age group 40-60 years (n=233, 76.89 to), had high frequency of developing Right ventricular infarction.

The other risk factors found were as hypertension (n= 152, 50.169c), followed by smoking (n=120, 39.609o),the patients with typical cardiac chest pain (n=285, 94.05'fo), The 709c of Right ventricular infarction patients were smokers, while 479c were diabetics and 49% had positive family history of coronary artery disease

CONCLUSION: Right ventricular infarction is present in near 1/3’^d of the patients with inferior wall myocardial infarction. Early detection, along with rapid reperfusion therapy, and knowledge of the potential complications can help to improve the outcome of patients with Right ventricular infarction.
