The classic definition of pulmonary arterial hypertension (PAH) is a mean pulmonary artery pressure (mPAP) of 20 mmHg. The gold standard for assessing pulmonary hemodynamics is right heart catheterization (RHC), which is necessary to confirm the diagnosis of PH. In some instances, RHC evaluates the degree of hemodynamic dysfunction and performs vasoreactivity tests. Measurement of the hepatic venous pressure gradient remains the gold standard diagnostic for identifying portal hypertension. This review aims to describe the procedure of RHC and the hemodynamic measurement in patients with PAH and Portopulmonary hypertension (PoPH). The RHC remains the gold standard for diagnosing PAH and PoPH.
肺动脉高压（PAH）的经典定义为平均肺动脉压（mPAP）为 20mmHg。评估肺血流动力学的金标准是右心导管检查（RHC），这对于确诊 PH 是必要的。在某些情况下，RHC 评估血流动力学功能障碍的程度并进行血管反应性测试。肝静脉压力梯度测量仍然是诊断门静脉高压的金标准。本篇综述旨在描述 RHC 程序以及 PAH 和门肺高压（PoPH）患者的血流动力学测量。RHC 仍然是诊断 PAH 和 PoPH 的金标准。
