摘要 目的:了解冠心病患者冠状动脉病变程度及范围与动态动脉僵硬指(AASI)的关系。方法:选取110例患者冠状动脉造影及24小时动态血压检查资料,根据CAG冠状动脉病变的程度分为3组:正常组(n=40):冠状动脉造影完全正常、内膜光滑。狭窄组(n=47):至少有1支冠状动脉有病变、腔径狭窄达50%以上,但未完全阻塞。闭塞组(n=23):至少有1支冠状动脉完全堵塞。根据CAG冠状动脉病变的血管支数分为4组:正常组(n=40),1支病变组(n=35),2支病变组(n=20),3支病变组(n=15)。通过24小时动态血压计算AASI:(AASI)=1-收缩压与舒张压直线回归的斜率。结果:1、冠脉狭窄组与冠脉闭塞组AASI均显著高于正常组;冠脉闭塞组AASI显著高于冠脉狭窄组。2、冠脉2、3支病变组AASI均显著高于正常组与冠脉1支病变组;冠脉2支病变组与冠脉3支病变组AASI比较无显著差异。结论:冠心病患者AASI显著升高提示冠状动脉狭窄程度重、病变范围广。
