Comparative evaluation of methods of myocardial scintigraphy using 99mTc-Sn-glucohepatonate and 99mTc-Sn-pyrophosphate in the diagnosis of acute myocardial infarction and unstable stenocardia

Scintigraphy with 99mTc -Sn-glucoheptonate permits the determination of the focus of transmural myocardial infarction at the earliest stages of the disease (from three hours to the fifth day of the disease) whereas scintigraphy with 99mTc -Sn-pyrophosphate makes it possible to follow-up the zone of...

Summary:Scintigraphy with 99mTc -Sn-glucoheptonate permits the determination of the focus of transmural myocardial infarction at the earliest stages of the disease (from three hours to the fifth day of the disease) whereas scintigraphy with 99mTc -Sn-pyrophosphate makes it possible to follow-up the zone of transmural infarction from Day 2 through Day 7-10. Both methods fail to provide enough information to diagnose non-transmural myocardial infarction. A comparative evaluation of the nature of glucohepatonate and pyrophosphate incorporation in the myocardium of patients with unstable angina is suggestive of the severity of ischemic changes in the myocardium.
