title: [Pyrophosphate-99mTc scintigraphy in stenocardia patients].
abstract: The authors examined 166 patients with ischemic heart disease and attacks of angina pectoris and 21 healthy individuals. Scintigraphy, electrocardiography and tests for the activity of creatine phosphokinase and its MB fraction were carried out at rest, during physical exercise and 1--3 days after it. It was found that pyrophosphate-99mTc may accumulate in the myocardium both during the attack of angina pectoris and after its cessation. Angina pectoris may occur both with diffuse and with focal pyrophosphate-99mTc accumulation in the myocardium. Positive results of scintigraphy were encountered considerably more often in patients examined during physical exercise than in those examined at rest. Scintigraphic signs of angina pectoris which occurs under the effect of physical exertion develop less frequently, but persisted for a longer time than its electrocardiographic signs.
