The results of cinecoronarography (cine-CG) and computerized subtraction angiography (CSA) in 60 CHD patients were analyzed. The percentage of narrowing of the coronary arterial diameter, the percentage of a stenosed area, the minimum diameter of a stenosed part and the extent of lesion were determined. Insignificant correlation was noted in important categories of lesions of medium extent and expression resulting from lesser spatial resolution of CSA.
