Coronary flow reserve was assessed by using a computer-assisted method in 26 normal controls and 45 patients with significant coronary artery stenosis ( > or = 50% luminal narrowing) and 16 patients with syndrome X. After intracoronary administration of papaverine, the diameter, cross sectional area, blood velocity, flow volume and reserve capacity of both left anterior descending (LAD) and right coronary arteries (RCA) were lower in patients with significant coronary stenosis than in controls. Despite similar changes in the diameter and cross sectional area, the velocity, flow volume and reserve capacity of these two vessels were also lower in patients with syndrome X than in controls. We conclude that coronary flow reserve is reduced in patients with coronary artery stenosis or syndrome X due to different levels of coronary artery abnormalities.
采用计算机辅助方法对26名正常对照者、45名有显著冠状动脉狭窄（管腔狭窄≥50%）的患者和16名X综合征患者进行了冠状动脉血流储备评估。冠状动脉内注射罂粟碱后，冠状动脉显著狭窄患者的左前降支（LAD）和右冠状动脉（RCA）的直径、横截面积、血流速度、血流量和储备能力均低于对照组。尽管X综合征患者的直径和横截面积变化相似，但其这两支血管的血流速度、血流量和储备能力也低于对照组。我们得出结论，由于冠状动脉异常程度不同，冠状动脉狭窄或X综合征患者的冠状动脉血流储备降低。
