摘要
目的了解超声检测首次脑梗死患者血管内皮依赖性舒张功能中的价值。方法用多普勒超声对97例高血压病合并首次脑梗死患者(高血压病组)及46例无高血压病、糖尿病和心脑血管疾病的患者(对照组)检查血管内皮依赖性舒张功能,测定两组患者肱动脉内皮依赖性舒张功能并进行对照分析。结果高血压病合并首次脑梗死患者反应性充血诱发的肱动脉内径百分变化率明显低于对照组(p<0.01),硝酸甘油诱发的肱动脉内径百分变化率与对照组无明显差别(p>0.05)。结论高血压病合并首次脑梗死患者存在血管内皮依赖性舒张功能障碍,超声检查对评价血管内皮依赖性舒张功能有重要价值。
Objective To investigate the value of uhrasonography in the examination of vascular endothelium-dependent vasodilation function in patients with first cerebral infarction. Methods Totally 97 cases of hypertension with first cerebral infarction （hypertension group） and 46 cases of control without hypertension, diabetes or cardiovascular and cerebrovascular diseases were examined with color Doppler uhrasonography. The vascular endothelium-dependent relaxation of brachial artery in two groups was examined and compared. Results The change percent of brachial artery diameter induced by reactive hyperemia was significantly lower in hypertension group than that in the control group （p〈0.01）. There was no statistical difference of the change percent of brachial artery diameter induced by nitroglycerin between the hypertension group and control group （p〉0.05）. Conclusion There is vascular endothelium-dependent vasodilation dysfunction in patients of hypertension with first cerebral infarction. It is important to evaluate the vascular endothelium-dependent relaxation with uhrasonography.
