左房应变评估左室舒张功能在心血管疾病中的临床应用价值

    Clinical application value of left atrial strain assessment of left ventricular diastolic function in cardiovascular diseases

    • 摘要: 左房应变是一个新兴的左房功能指标,可以在整个心脏周期内对左房心肌力学进行分析测量,量化心脏的舒张功能,具有多种重要的临床应用。在心血管疾病中,左房功能改变要早于左房结构重构,通过斑点追踪测量左房应变发现左房功能异常,及早识别疾病恶性进展及不良事件增加的风险,并早期干预,对改善患者风险分层、预后具有重要意义。本文综述已发表的关于左房应变的最新临床证据,并讨论其临床意义、最新应用和前景。

       

      Abstract: Left atrial strain, an emerging indicator of left atrial function, allows for the analysis and measurement of left atrial myocardial mechanics throughout the entire cardiac cycle, quantifying the cardiac diastolic function with various significant clinical applications. In cardiovascular diseases, alterations in left atrial function precede structural remodeling of the left atrium. By identifying abnormal left atrial function through the measurement of left atrial strain, timely recognition of malignant disease progression and increased risk of adverse events can be achieved, enabling early intervention to improve risk stratification and prognosis for patients. This review summarizes the published clinical evidence regarding left atrial strain and discusses its clinical significance, latest applications and future prospects.
