[Myocardial 99mTc-pyrophosphate scintigraphy during bicycle ergometry as a method of evaluating the severity of chronic ischemic heart disease].
The time course of myocardial 99mTc-pyrophosphate accumulation 1 hour after a bicycle ergometric test versus the resting scintigraphic findings was correlated with the severity of chronic coronary heart disease (CHD) and long-term prognosis. A group of the patients who had higher radiotracer accumulation following the exercise showed the most severe disease and unfavorable prognosis (in this group 19.4% deaths were observed during a three-year follow-up). A single administration of 99mTc-pyrophosphate followed by scintigraphy 2 hours after bicycle ergometry and repeated scintigraphy 1 hour later allows one to assess the time course of myocardial radiotracer accumulation and to judge how the myocardium is supplied by blood.
