[Pathological perfusion scintigram of the myocardium in angina pectoris patients with normal coronary angiograms (author's transl)].

In patients aged 24 to 45 years with angina pectoris, pathological changes in the exercise electrocardiogram and a normal coronary angiogram, a disturbance of the pattern of myocardial perfusion could be demonstrated in addition by scintigraphy. The cause of this disturbance of myocardial perfusion is unknown. Myocardial scintigraphy is indicated (1) to demonstrate an otherwise undetectable disturbance in the blood flow of the myocardium with a morphologically normal coronary system, (2) in subtotal coronary stenosis before the decision to perform a coronary bypass operation is made, (3) in cases of anginal syndrome with normal coronary angiograms.
