1、心衰超声指数评价左室射血分数正常心衰的应用价值李金芳1张志新2韩冰1(1山东省威海市立医院山东威海264200)(2中国人民解放军四零四医院心脏中心山东威海264000)【摘要】目的：采用综合超声心动图多项参数的心衰超声指数来评价左室射血分数正常心衰(HFNEF)患者的心功能。资料与方法：选取2014年6月至2015年10月山东省威海市立医院心内科HFNEF患者60例(HFNEF组)和正常门诊患者60例(对照组)，所有入选者均采用心衰超声指数进行评分，并将该评分与同期NT-BNP检测结果及纽约心功能分级进行比较。结果：心衰超声指数在HFN

2、EF组明显高于对照组(P<0.01),且随着纽约心功能分级的升高而升高，心功能II、III、IV级患者的心衰超声指数值分别为2.11±0.90、3.34±0.97、5.33±1.60o相关性分析表明心衰超声指数与NT-BNP高度相关(r=0.92)。结论:心袞超声指数能够准确判断心力衰竭分级，且与BNP具有良好相关性，是判断心力衰竭病情及预后的理想指标。【关键词】心力衰竭，心衰超声指数；氨基末端脑钠肽前体【中图分类号】R541【文献标识码】A【文章编号】1007-8231(2015)13-0115
