[Possibilities of the use of 99mTc pyrophospate myocardial scintigraphy in the early period of myocardial infarct in the evaluation of the effectiveness of thrombolytic therapy].

In early (mean time, 6.9 +/- 0.2 hours following the onset of an anginal episode), 99mTc pyrophosphate myocardial scintigraphy was performed in 28 patients who received thrombolytic therapy under angiographic monitoring. The sensitivity and specificity of an early administration of pyrophosphate into the myocardium as a noninvasive marker of successful coronary reperfusion was 95.7% and 100%, respectively.
