Pulmonary hypertension (PH) is a complex multiorgan system disease defined as mean pulmonary artery pressure (mPAP) > 20 mmHg. The etiologies related to pathological changes in pulmonary vasculature leading to PH are wide. Hemodynamic categorization considers precapillary PH, represented by pulmonary arterial hypertension (PAH), pulmonary vascular resistance (PVR) > 3 Woods units (WU), and pulmonary arterial wedge pressure < 15 mmHg. Postcapillary PH, represented by left heart disease, involves PVR > 3 WU and pulmonary arterial wedge pressure > 15 […]
