title: Evaluation of radiopharmaceuticals for the detection of acute myocardial infarction in man.
abstract: The accuracy of the scintigraphic diagnosis of acute myocardial infarction with 99mTc-pyrophosphate, 99mTc-tetracycline and 99mTc-glucoheptonate was assessed in 63 patients, 43 of whom had clinical evidence of acute myocardial infarction. In 15, studies with both 99mTc-tetracycline and 99mTc-pyrophosphate were performed. Accuracy was greatest with 99mTc-pyrophosphate (17/17 true positives, 8/10 true negatives) contrasted with 99mTc-tetracycline (12/25 true positives, 6/11 true negatives) and 99mTc-glucoheptonate (3/13 true positives, 2/2 true negatives). 99mTc-pyrophosphate was the most sensitive tracer for the detection of acute myocardial infarction. The diagnostic accuracy with 99mTc-glucoheptonate was poor.
