Abstract It is well known that the seriousness of the hemodynamic sequelae of myocardial infarction is related directly to the amount of myocardium that is lost due to infarction Proximal LAD occlusion has been documented as an independent predictor of poor outcome related to higher mortality and recurrent MI and distal LAD occlusion is considered to have a better outcome The outcome of patients with AMI in the inferior wall depends in large part on the occluded artery (RCA or LCX).Patients with AMI due to occlusion in the RCA (80% of cases) usually have a poorer outcome than do those with occlusion of the LCX, mainly due to associated complications (hemodynamic changes due to right ventricular involvement and conduction disturbances The aim of this study was to assess the accuracy of previously defined ECG criteria determined from ECG angiographic correlative studies in predicting not only the infarct-related artery (IRA) but also the site of the culprit lesion within that artery in patients presenting with signs and symptoms of an acute coronary event. |
