Abstract

Purpose of review: In this review, we provide an overview of the echocardiographic evaluation of the pulmonary circulation - right ventricular functional unit during exercise and its clinical value.

Recent findings: An increased understanding on the physiological response of pulmonary hemodynamics during exercise and evidence of the impact of an abnormal mean pulmonary arterial pressure (mPAP)/cardiac output (CO) slope on survival led to the reintroduction of exercise pulmonary hypertension (EPH), defined as a mPAP/CO slope >3 mmHg/l/min, in the current European Society of Cardiology/European Respiratory Society (ESC/ERS) guidelines for pulmonary hypertension. Additionally, noninvasive exercise echocardiography may enable easy and readily available assessment of pulmonary exercise hemodynamics.

Summary: Impaired pulmonary exercise hemodynamics are considered early hemodynamic signs of cardiopulmonary disease. In order to diagnose EPH, exercise right heart catheterization (RHC) is needed, which is invasive, highly cost- and staff intensive and reserved to expert centers. Noninvasive surrogates derived from exercise echocardiography might be an appropriate alternative to invasive RHC.

运动时肺循环和右心室功能单位的超声心动图评价及其临床价值。

综述目的：本文就运动时肺循环-右心室功能单元的超声心动图评价及其临床价值作一综述。最近的研究发现：在当前的欧洲心脏病学会/欧洲呼吸学会（ESC/ERS）肺动脉高压指南中，对运动期间肺血流动力学生理反应的了解增加以及异常平均肺动脉压(mPAP)/心输出量（CO）斜率对生存影响的证据导致运动性肺动脉高压（EPH）的重新引入，定义为mPAP/CO斜率bbb30 mmHg/l/min。此外，无创运动超声心动图可以方便和容易地评估肺运动血流动力学。摘要：肺运动血流动力学受损被认为是心肺疾病的早期血流动力学征象。为了诊断EPH，需要进行运动右心导管（RHC），这是一种有创的、高成本和人员密集的、保留在专家中心的方法。由运动超声心动图获得的非侵入性替代物可能是侵入性RHC的合适替代品。
