Frequency and in-Hospital Mortality of Right Ventricular Infarction in Patients of Inferior ST-Segment Elevation Myocardial Infarction

Aim: To evaluate frequency and in-hospital mortality of right ventricular infarction in patients of inferior ST-segment elevation myocardial infarction. Methods: The study was descriptive case series. The study included 150 consecutive patients with inferior ST-segment elevation myocardial infarction (STEMI). Inferior STEMI was diagnosed by STsegment elevation in electrocardiographic leads II, III & aVF and RV infarction was diagnosed by clinical examination (low blood pressure, raised JVP and clear lung fields), further augmented by STsegment elevation in right precordial ECG leads especially V-4R. The numerical variables were presented as mean and standard deviation while qualitative variables were presented as frequency and percentage. Results: The mean age was 55 +/- 11.9 years and 80% patients were male. Of 150 patients, 36(24%) were having inferior STEMI with RVI. In-hospital mortality rate was 10(28%) in patient inferior MI with RVI. Conclusion: RVI frequently complicates inferior MI and results in increase in mortality.
