[Prognostic importance of a positive test of myocardial 99mTc-Sn-pyrophosphate accumulation in patients with stable stenocardia].

The paper reports the results of a retrospective study of the frequency of complications of chronic coronary disease in 51 patients with stable angina subjected to myocardial 99mTc-Sn-pyrophosphate scintigraphy at rest at first screening. In the group with positive scintigraphic results, myocardial infarction and death from cardiac causes was five times as frequent within the next five years as it was in the group where myocardial incorporation of the drug was not observed. The frequency of complications was higher in cases where positive scintigraphic results were combined with cardiomegaly and electrocardiographic signs of transitory ischemia. Positive scintigraphic test with 99mTc-Sn-pyrophosphate can indicate future aggravation of the disease in patients with stable angina pectoris.
