RESUMEN
Objectives: to find out the frequency of right ventricular infarction [RVI] in patients with acute inferior wall myocardial infarction and also to see its clinical correlation and prognostic value
Methods: 198 consecutive patients with acute inferior wall myocardial infarction [MI] were enrolled. Elevated ST segments in V4R or V3R to V6R were used to diagnose RVI. We assessed the incidence of ST-segment elevation in these leads and their correlation on clinical ground
Result: in 96 patients [48.5%], RVI was present. Clinical correlation showed that raised JVP was present in 58.5% and raised JVP with hypotension in 34.5% of patients. Normal JVP was present in 41.5% of patients in which 22% of patients were with hypotension and 20% of patients were without clinical findings. Hypotension observed in 53% of patients. Complications were higher in patients with elevated ST segments in V4R [51%] in contrast to those without RVI [21%]. In-hospital mortality was more than double in RVI Group
Conclusion: RVI in acute inferior MI is common. Elevated ST segments in V4R or V3R to V6R can be used to diagnose RVI. Clinical correlation can help but may not be diagnostic and it has higher mortality compared to inferior MI alone
