FREQUENCY AND IN-HOSPITAL MORTALITY OF RIGHT VENTRICULAR MYOCARDIAL INFARCTION IN PATIENTS WITH INFERIOR WALL MYOCARDIAL INFARCTION

Abstract

Objective: To determine the frequency and in-hospital mortality of right ventricular myocardial infarction, in patients with inferior wall myocardial infarction. Methods: This was a descriptive case series, conducted at Cardiology Department, Rehman Medical institute during time duration 18th Feb 2017 to 18th Aug 2017. The study was conducted after approval was obtained from the hospital ethical review committee. Sample selection was done through a non-probability consecutive sampling technique. Patients were included in the study based on inclusion and exclusion criteria. A detailed history was taken followed by a complete physical examination and ECG was done. Demographic and outcome data were noted on a predesigned Performa. Results: The mean age (SD) of patients in this study was 68±11.05 years. 94 (60.64%) patients were male while 61 (39.35%) patients were female. Among patients 142 (91.61%) were smokers, 136 (87.74%) patients were hypertensive and 123 (79.35%) patients were diabetic. A total of 155 patients were hospitalized with the diagnosis of acute inferior STEMI. Of the total 155 in-patients, 56(36.1%) were having right ventricular infarction. In-hospital mortality was recorded in 39/155(25.16%) patients during hospitalization having right ventricular myocardial infarction with inferior wall myocardial infarction. Conclusion: This study concluded that Right Ventricular Infarction can occur in patients with Inferior Wall Myocardial Infarction with certain adverse in-hospital outcomes such as mortality.
