Understanding Pulmonary Arterial Hypertension (PAH)

• PAH is a condition characterized by high blood pressure in the arteries of the lungs, requiring careful management to prevent complications.

Medications Used in PAH Treatment

• Key drug classes include endothelin receptor antagonists (e.g., Bosentan), phosphodiesterase-5 inhibitors (e.g., Sildenafil), prostacyclin analogs (e.g., Epoprostenol), and soluble guanylate cyclase stimulators.

Supportive Therapies

• Oxygen therapy to improve oxygen levels.
• Diuretics for fluid retention management.
• Anticoagulants if there's a risk of blood clots.

Lifestyle and Monitoring

• Regular follow-up and monitoring are crucial.
• Lifestyle changes such as avoiding strenuous activities and managing diet are recommended.

Advanced Treatments

• Surgical options like atrial septostomy or lung transplantation may be considered in severe cases.

Relevant Medical Specialties

• Cardiologists and pulmonologists play key roles in managing PAH.
