How Pulmonary Arterial Hypertension Impacts Heart and Lung Health
Pulmonary Arterial Hypertension (PAH): A Serious Cardiopulmonary Condition
Pulmonary Arterial Hypertension (PAH) is a progressive, life-threatening disorder characterized by high blood pressure in the arteries that supply the lungs. This increased pressure forces the heart to work harder to pump blood, which can eventually lead to heart failure if left untreated.
Understanding Pulmonary Arterial Hypertension
PAH occurs when the small arteries in the lungs become narrowed or blocked, increasing the resistance to blood flow. Over time, this causes elevated pressure within the pulmonary arteries and places significant strain on the right side of the heart.
Causes and Risk Factors
While the exact cause of PAH is often unknown (idiopathic), several factors can contribute to its development:
Genetic mutations
Connective tissue diseases (such as scleroderma or lupus)
Congenital heart defects
Chronic liver disease
HIV infection
Use of certain drugs or toxins (including some appetite suppressants)
Symptoms of PAH
PAH symptoms are often non-specific in the early stages but worsen as the disease progresses:
Shortness of breath (dyspnea)
Fatigue
Chest pain
Dizziness or fainting (syncope)
Swelling in the ankles, legs, or abdomen (edema)
Rapid heartbeat (palpitations)
Diagnosis and Treatment
Diagnosis:PAH is typically diagnosed through a combination of physical examination, echocardiogram, right heart catheterization, pulmonary function tests, and other imaging techniques.
Treatment Options:While there is no cure, treatments can manage symptoms and slow disease progression:
Vasodilators (help relax blood vessels)
Endothelin receptor antagonists (reduce blood vessel constriction)
Phosphodiesterase-5 inhibitors (improve blood flow)
Prostacyclin analogs (dilate pulmonary arteries)
Oxygen therapy
Lifestyle modifications and supervised exercise
In severe cases, lung transplantation may be considered.
