摘要 目的 采用无创性血管超声检查方法探讨高血压病患者内皮功能的变化。 方法 冠心病患者 2 0例 ,其中急性心肌梗死 11例 ,陈旧性心肌梗死 5例 ,不稳定型心绞痛 4例 ,年龄 5 4岁~ 6 5岁 ,平均年龄 6 2 5岁± 7 7岁 ;男性 13例 ,女性 7例。另设健康对照组 2 0例 ,其中男性 12例 ,女性 8例 ,平均年龄 5 9 5岁± 4 9岁 ,各组间年龄、性别构成比均无显著性差异 (P>0 0 5 )。所有受检对象均用二维超声心动图测量基础肱动脉内径 (D0 ) ,并用脉冲多普勒测量基础平均血流速度 (V0 )。阻断前臂血流 5分钟后开放血流 ,再重复测定肱动脉内径变化、内径变化率及血流量变化、血流量变化率。 结果 基础状态下各组血管内径及血流量无显著性差异 ;反应性充血后血管内径变化率、血流量变化率正常对照组明显高于冠心病组 (P <0 0 5 )。 结论 冠心病患者早期即存在血管内皮功能损害。无创性超声检测血管内皮功能为简便、实用、价廉的测试手段。
