title: [The accuracy of 201 thalium scintigraphy of the heart under conditions of stress (author's transl)].
abstract: The results of 201 thalliumszintigraphy under stress condition in patients with coronary heart disease with or without myocardial scars have not been uniform. We could show that pathologic stress szintigrams were only found in patients with a singular stenosis in one branch of the left coronary artery. In all those cases who had similar stenosis in both branches of the left coronary artery the stress szintigram appeared to be unchanged or normal. Therefore an unchanged stress szintigram allows no conclusion on the condition of the coronary arteries. A normal stress szintigram can be found as well in patients with normal coronary arteries as in patients with severe coronary heart disease. The examination of 201 thallium szintigrams under stress conditions therefore needs some critical evaluation.
