Abstract
Unlabelled:
Perfusion scintigrams with Technetium-labeled microspheres were performed in 60 patients undergoing selective coronary angiography. The scintigrams were analyzed semiquantitatively with the aid of a computer. In addition, angiograms were quantitated with regard to proximal obstructions as well as regional wall changes of the left ventricle (VCF).
Results:
1. A reduction of scintigraphic activity was already seen in narrowings of lesser degrees (50%); 2. scintigraphic activity followed the degree of obstruction rather than the contraction abnormality. Perfusion scintigrams are helpful in selecting patients for revascularization.
