THE PREVALENCE OF RIGHT VENTRICULAR INFARCT IN PATIENTS WITH INFERIOR WALL MI
Background: To study the prevalence of right ventricular infarct in patient with acute inferior wall MI presenting to CCU
unit, Hayatabad Medical Complex, Peshawar. An observational study was conducted from February 2015 to March 2015.
Methods: A cross sectional study, in which a total 60 patients with acute inferior wall MI, fulfilling the inclusion and
exclusion criteria were enrolled after taking an informed consent. A full history including age,sex,family history of
IHD,hypertension,diabetes mellitus,smoking, dietary risk factors, physical inactivity was taken along with complete
physical examination, ECG and cardiac enzymes.Data was analyzed using the analytical tool of Microsoft Excel 2007.
Quantitative variables were analyzed and represented as percentage.
Results: Out of 60 patients, 36(60%) were male and 24(40%) were female, 28(46.6%) hypertensive, 22(36.6%) dia-
betic, 8(13.3%) smokers, 32(53.3%) with positive family history of IHD and 15(25%) were physically inactive.Age was
grouped as 40 to 49 years 9(15%), 50 to60 years 31(51.6%), greater than 60 years 20(33.3%). Dietary risk factors were
included as saturated fats consumption 47(78.3%), Red meat consumptions was grouped as Less than 1 per week
17(28.3), once a week 20(33.3%), twice a week7(11.6%), greater than twice a week16(26.6%). Egg yolk consumption
was grouped as Less than 1 per week 42(70%), once a week 5(8.3%), twice a week 4(6.6%), greater than twice a week
9(15%). Patients with RV infarct were 13(21.6%).ECG was the diagnostic modality to diagnose acute RVMI. V4R was
the most sensitive lead for RVMI diagnosis with sensitivity of 80%.
