In order to determine the severity of contraction abnormalities in acute myocardial infarction and their response to sublingual nitroglycerin, 23 patients were studied by radionuclide angiography within 6-24 hours after the onset of chest pain. Radionuclide angiograms were obtained in the right anterior oblique projection before and after nitroglycerin and segmental shortening was determined us...
