Background: Myocardial infarction is diagnosed when cardiac biomarkers rise, together with supporting evidence such as usual symptoms, suggestive electrocardiographic changes, or imaging evidence of new loss of viable myocardium or new regional wall motion abnormality. While an electrocardiogram is normal, echocardiography is not used in the emergency room. In Ethiopia, data on electrocardiogram and echocardiogram findings, as well as their impact on mortality, is still scarce. This research can be a reference for next researches.
