  • Abstract
  • Look Inside

To evaluate coronary vasodilatory reserve in syn-drome X, left coronary arteriography and continuous measurement of coronary venous oxygen saturation (CSO2-Sat) were performed during intracoronary injec-tion of papaverine (PAP) and acetylcholine (ACh) in 11 patients of syndrome X and 13 control subjects. Coronary diameter after PAP increased 10.2 % in the control group and 9.8 % in the syndrome X group, but after ACh decreased 1.7 % in the control group and decreased 2.3 % in the syndrome X group. These changes in coronary diameter by PAP and ACh in the two groups were not significantly different.
