肺动脉高压(PAH)是一种致命的疾病,其特征表现为肺血管重构,肺血管阻力(PVR)逐渐升高,进一步导致右心衰和死亡。PAH主要被归为第I大类肺动脉高压,但仍有其他不同病因(第II、III、IV、V大类)继发的肺动脉高压(pulmonary hypertension, PH) 。混合性毛细血管后性肺高压(CpcPH)属于第II大类肺动脉高压。 2013年首次...

Pulmonary hypertensionMagnetic resonance imagingIntroduction:Combined pre- and post-capillary pulmonary hypertension (Cpc-PH) is the most severe form of PH-LHF. While the impact of elevated left atrial and consequently elevated pulmonary venous (PV) pressure on Cpc-PH progression is well studied, ...
