超声心动图在脓毒症心肌病中的应用进展

Advances in the application of echocardiography in septic cardiomyopathy

脓毒症心肌病(SCM)是由脓毒症引起的急性心功能障碍,文献报道其发病率为13.8%~60.0%,病死率高,可达70%~90%,目前尚无诊断的金标准,也无特异性指标以判断预后。超声心动图因其具有可视化、无创、可床旁操作、可重复再现等优势,被广泛应用于SCM的研究中。不同类别的超声,具有不同的特点,比如常规传统超声心动图硬件设备已很成熟,参数容易获取;经食道超声参数更加精确;斑点追踪超声心动图参数敏感度高等。本文对近年来超声心动图技术在SCM中的应用进行总结和综述,以期为临床医生对SCM的早期诊断及预后判断提供参考依据。

Septic cardiomyopathy(SCM)is an acute heart dysfunction caused by sepsis.Literature reports its incidence fluctuating between 13.8%and 60.0%,with a high mortality rate of 70%to 90%.Currently,there is no gold standard for diagnosis,nor specific indicators to assess prognosis.Echocardiography is widely used in SCM research due to its advantages of visualization,non-invasiveness,bedside operation,and reproducibility.Different types of ultrasounds have unique characteristics,for example,conventional echocardiography hardware is well-established with easily obtainable parameters,transesophageal echocardiography provides more accurate parameters,and speckle tracking echocardiography has high sensitivity.This article summarizes and reviews the application of echocardiographic techniques in SCM in recent years,aiming to provide clinical doctors with reference for early diagnosis and prognostic assessment of SCM.
