Abstract

88 Patients admitted to a coronary care unit with chest pain of varying etiology, but without ECG evidence of an acute transmural myocardial infarction, had myocardial scintigrams using technetium 99m stannous pyrophosphate. (99(m)Tc PYP). 17 Of these patients had ECG and enzymatic evidence suggestive of acute subendocardial myocardial infarction. In each of these, the scintigrams were positive demonstrating increased 99(m)Tc PYP uptake either in a faintly but diffusely positive pattern, or in a well localized strongly positive one. The remaining 71 patients did not evolve ECG or enzymatic evidence of acute myocardial infarction. In each of these patients, the myocardial scintigram was negative. Thus 99(m)Tc PYP myocardial scintigrams are capable of identifying the presence of acute subendocardial myocardial infarction in patients. The absolute frequency with which subendocardial myocardial infarction can be recognized utilizing this technique will have to be established in a larger number of patients in the future.
