摘要 目的 探讨原发性高血压患者左心室质量指数与肱动脉内皮功能的关系。方法 入选 46例为原发性高血压患者和 2 9例健康志愿者。检测体重、身高、血压、血浆内皮素、心脏超声测量左心室后壁厚度、室间隔厚度、左室舒张末径及左室收缩末径 ,采用无创性血管多普勒超声技术测量肱动脉基础内径 ,反应性充血后血管内径 ,含服硝酸甘油后血管内径及反应性充血后血流量变化。结果 高血压组的血浆内皮素水平及左心室质量指数均高于对照组 [( 81 0 0±14 0 2 )vs( 4 7 2 7± 13 2 0 )pg/ml ,( 12 8 0 6± 15 0 5 )vs( 10 0 66± 17 99) ;P <0 0 5 ] ,肱动脉基础内径 ,含服硝酸甘油后的血管内径变化及反应性充血后的血流量增长百分率两者差异无显著性 [( 3 68± 0 417)vs( 3 5 4± 0 40 6)mm ,( 13 41± 5 44 ) %vs( 14 41± 7 94) % ,( 684± 14 5 ) %vs( 682± 12 9) % ;P >0 0 5 ] ,反应性充血后血管内径变化之间差异有显著性 [( 5 0 6±0 3 5 4) %vs( 8 0 6± 0 43 ) % ,P <0 0 1]。在高血压组、左室肥厚组和非左室肥厚组之间血浆内皮素水平 [( 83 0 8± 12 2 1)vs( 68 2 4± 11 2 0 )pg/ml,P <0 0 1]和反应性充血后血管内径变化 [( 4 0 7± 0 415 ) %vs( 5 12± 0 44 2 ) % ,P <0
