Pulmonary Arterial Hypertension (PAH)

Pulmonary arterial hypertension (PAH) is a type of high blood pressure that affects the arteries in the lungs and the right side of the heart. It leads to narrowing and stiffening of the pulmonary arteries, increasing the workload on the heart. Symptoms include shortness of breath, chest pain, and fatigue. Treatment options include medications, oxygen therapy, and sometimes lung transplantation.
