Pulmonary arterial hypertension (PAH) is a progressive and a life-threatening condition characterized by high pulmonary blood pressure, remodeling of small pulmonary blood vessels and increased vascular resistance leading to right heart failure. According to the 6th World Symposium on Pulmonary Hypertension, PAH is defined by concomitant elevation of three parameters: mean pulmonary arterial pressure (mPAP) > 20 mmHg; pulmonary arterial wedge pressure (PAWP) ≤15 mm Hg; pulmonary vascular resistance (PVR) ≥ 3 Wood Units. The right heart failure is due […]
