Analysis on improvement of left ventricular end diastolic diameter after cardiac resynchronization therapy

摘要

摘要: 目的探讨对再同步化治疗(CRT)后左室舒张末期内径(LVEDd)改善有影响作用的因素.方法选取在鼓楼医院成功植入CRT的43例患者,搜集其术前、术后6个月随访的资料,通过相关性分析、t检验、方差分析、多元回归分析,筛选出最能影响术后LVEDd改善程度的因素.结果单因素分析显示,年龄、病程,基础心电图的QRS时限、是否患有高血压、糖尿病,性别,是否为缺血性心肌病,术前的LVEDd,术前心电图是否为左束支传导阻滞,左室电极的位置,二尖瓣返流程度均对LVEDd的改善程度无显著的影响.多元线性回归分析显示,术前LVEDd、性别、是否有糖尿病3个因素与LVEDd的改善程度线性相关,其回归系数分别为-0.17(P=0.026)、-0.23(P=0.052)和-0.18(P=0.084).结论术前的LVEDd、性别、糖尿病史与术后LVEDd改善程度线性负相关,相关程度较弱,但具有一定的预测作用.
