摘要
目的 采用无创性血管超声检查方法探讨各级高血压病患者血管内皮功能的变化。方法 原发性高血压(EH)患者88例,根据血压值级别分为三组,所有受检对象均用二维超声测量基础肱动脉内径(D),并用脉冲多谱勒测量基础平均血流速度(V)。阻断前臂血流5分钟后开放血流,再重复测定肱动脉反应性充血时的D及V,测算肱动脉内径变化、内径变化率及血流量变化、血流量变化率,并与正常组相比较。结果(1)基础状态下各组间血管内径及血流量差异无显著性;(2)反应性充血后上述四参数均为Ⅱ级组<Ⅱ级组<Ⅰ级组<正常组,且差异均有显著性(P<0.05~0.001);(3)高血压病人血流量变化率与平均血压值呈显著负相关(r=-0.60,P<0.001),内径变化率与平均血压值亦呈显著负相关(r=-0.62,P<0.001)。结论 原发性高血压病患者随血压值升高,血管内皮功能损害显著加重;无创性超声是检测血管内皮功能简便、实用、价廉的手段。
