Clinical Study Of Acute Inferior Wall Myocardial Infarction With Special Reference To Right Ventricular Infarction

Jemshad Alungal, Mansoor C. Abdulla

Abstract :

Background and Objectives: To study the clinical presentation of acute inferior wall myocardial infarction and also to study incidence, clinical features and prognosis of right ventricular infarction in inferior wall myocardial infarction. Methods : Fifty consecutive cases of inferior wall infarction was included after excluding patients with previous infarction, bundle anch block, clinical evidence of corpulmonale, pre–excitation syndrome and suspected pulmonary embolism. A detail history was taken in all the patients and through physical examination was done. A 16 lead ECG consisting 12 conventional leads and 4 right side chest leads was recorded at the time of admission and also as per need. Results: Incidence of right ventricular infarction is about 40% in inferior wall myocardial infarction. Most of the patients (98%) presented with retrosternal chest pain associated with sweating. Raised jugular venous pressure (32%), hypotension (28%) adycardia (28%) , Kussmaul’s sign (20%) and RV S3/S4 were more common in patients with right ventricular infarction. Clinical complications were common in patients with right ventricular infarction (60%). Interpretation and Conclusion: Incidence of right ventricular infarction in inferior wall infarction is fairly common. All cases of inferior wall infarction should have right sided chest leads recorded during ECG examination. If diagnosis of right ventricular infarction is correctly made and treated the prognosis is usually good.
