摘要 目的应用超声心动图评价卡维地洛(达利全)对原发性高血压患者左心室肥厚和舒缩功能的影响。方法分别于卡维地洛(达利全)治疗前和治疗24周后,对60例原发性高血压患者进行超声心动图检查。M型超声心动图测量舒张末期左心室内径、室间隔和左心室后壁厚度,计算左心室质量指数;在心尖左心长轴切面上,用多普勒超声心动图测量二尖瓣口舒张早期峰值速度E、舒张晚期峰值速度A和E峰减速时间,并计算E/A比值,根据Teichholz公式及主动脉根部血流频谱自动计算心输出量(CO)和左室射血分数(LVEF)。结果卡维地洛治疗24周后,左心室质量指数从(123±22)g/m2减低为(101±23)g/m2(P<0.001);E/A(1.26±0.26)明显高于服用前(0.95±0.26),P<0.001;E峰减速时间从(220±33)ms下降到(181±26)ms(P<0.001)。心输出量及左心室射血分数治疗前后差异无统计学意义。结论卡维地洛治疗24周使原发性高血压患者左心室肥厚得到消退,并改善了其舒张功能。
