Abstract
In order to recognize and quantitate abnormalities in wall segment motior in 22 patients simultaneous measurements of isovolumic and ejection phase parameters were performed with the MILLAR-angiographic catheter at rest, after leg raising, and during bicycle exercise. Six patients had slight (stenosis less than 50%) or no coronary heart disease (CHD) (group I), 16 patients had severe CHD (group II, stenosis of more than 50% in 1–3 main branches). During volume load in all patients of group II, a decrease of peak measured velocity (Vpm) and the velocity of circumferential fiber shortening (Vcf from 1.4 to 1.1 circ/sec, p < 0,025) occurred. In group I, Vcf increased (p < 0,05) (Fig. 1).
