Abstract
To investigate the effect of Amrinone (AMR) on left ventricular regional wall motion, we performed contrast ventriculography before and after administration of AMR in patients with myocardial infarction. Three patients had anterior myocardial infarction, one had inferior infarction, and one had posterior infarction. All patients had abnormal regional wall motions corresponding with the territory of electrocardiographic abnormal ities. In four of the five patients the regional wall motions of the infarct area were improved by administration of AMR (1mg/kg). The results suggest that the positive inotropic effect of AMR may influence not only normal myocardium but also stunned myocardium.
