Circulation:运动状态下的超声心动图在HFpEF诊断中的作用

2017-01-07 xing.T MedSci原创

目前提出的基于静息状态下数据的HFpEF诊断指南并不敏感。加入运动状态下E/e’的数据可以提高灵敏度和阴性预测值,但特异性有所下降,提示运动超声心动图检查可帮助排除HFpEF。这些结果对当前单纯基于静息状态下数据的HFpEF排除方法提出了质疑,加强使用运动状态下的有创和无创血流动力学评估可以明确地证实或排除HFpEF的诊断。

诊断射血分数正常的心力衰竭(HFpEF)是具有挑战性的,在很大程度上依赖于心室充盈压(肺毛细血管楔压,PCWP)增高来确诊。目前的指南推荐使用利尿钠肽(NT-proBNP)和休息/运动超声心动图(E/e’的比值)来确诊。支持这种做法的研究数据相互矛盾,近日,心血管领域权威杂志Circulation上专门针对这一问题发表了一篇研究文章。

研究者对经无创证实的HFpEF患者(n=50)和有呼吸困难但无确定心脏病(n=24)参与者分别在休息和运动状态下进行前瞻性的同步超声心动图导管研究。

研究者发现18%的HFpEF患者NT-proBNP水平低于HFpEF排除水平(≤125 pg/ml)。E/e’比值与在休息(r=0.63,P<0.0001)和运动(r=0.57,P<0.0001)状态下直接测量的PCWP有关。具体而言,目前的指南并不敏感,单纯的以静息状态下的超声心动图数据得到的无创确诊的HFpEF患者只有34-60%。增加运动状态下的超声心动图数据(E/e’比值>14)可以改善敏感性(90%)和阴性预测值,但特异性下降(71%)。

由此可见,目前提出的基于静息状态下数据的HFpEF诊断指南并不敏感。加入运动状态下E/e’的数据可以提高灵敏度和阴性预测值,但特异性有所下降,提示运动超声心动图检查可帮助排除HFpEF。这些结果对当前单纯基于静息状态下数据的HFpEF排除方法提出了质疑,加强使用运动状态下的有创和无创血流动力学评估可以明确地证实或排除HFpEF的诊断。
