Primary (idiopathic) pulmonary arterial hypertension is sustained elevated pulmonary-artery pressure (mean PA >25 mmHg at rest) due to pulmonary vascular remodeling, presenting with exertional dyspnea, fatigue, syncope, and right-heart failure. Treatment: risk stratification; supportive (diuretics, oxygen, anticoagulation); PAH-specific therapy (endothelin-receptor antagonists, PDE-5 inhibitors, prostanoids, prostacyclin analogs); lung transplantation for advanced; treat underlying cause if associated.
Exertional dyspnea; fatigue/syncope; right-heart failure; elevated PA pressure; young female predominance
Pulmonary-arterial remodeling raises PVR, causing RV pressure overload and failure.
Supportive (diuretics/oxygen/anticoag); PAH-specific therapy (ERA/PDE5i/prostanoids); transplant for advanced
Early diagnosis; PAH-specific therapy; avoid pregnancy/high altitude.
