摘要 目的对比单纯左室起搏与双室起搏分别治疗HF伴CLBBB的短期疗效。方法选择2004年2月~2009年3月于我院住院HF伴CLBBB患者25例,男17例,年龄(61.28±9.271)岁,所有患者均符合2008 ACC/AHA/HRS公布的心脏节律异常器械治疗指南CRT的Ⅰ类适应症;将25例患者随机分为LV组(12例)与BV组(13例),于术前和术后3、6个月对其进行自身交叉配对研究。研究内容包括:明尼苏达心力衰竭生活质量评分、纽约心脏病学会(NYHA)心功能分级、6分钟步行试验(6-MWT)、超声心动图检查指标。结果 6个月随访结束时,两组术后临床及超声指标较术前均有明显改善(P<0.001);两组间比较,LVEF、6-MWT改善幅度BV组大于LV组,分别为(60%Vs 49%,P=0.043)、(85%vs 69%,P=0.027),而生活质量评分(56%vs 50%)、NYHA分级(59%vs 57%)、LAEDD(14%vs 15%)、LVEDD(13%mm vs 14%),两组间均无统计学差异(P>0.05)。结论心力衰竭伴完全性左束支传导阻滞患者经单纯左室起搏或双室起搏治疗后均能改善患者心功能和活动耐量,但双室起搏LVEF、6-MWT短期治疗效果优于单纯左室起搏。
