Overview

Pulmonary hypertension (PH) occurs when pressure in the pulmonary arteries—the vessels that carry blood from the heart to the lungs—becomes abnormally high. That elevated pressure forces the right side of the heart to work harder and makes the lungs less efficient at exchanging oxygen. People with PH commonly experience shortness of breath, reduced exercise capacity, fatigue, chest discomfort, and swelling in the legs or abdomen. Management aims to relieve symptoms, preserve function, and slow disease progression through individualized treatment plans that may combine medicines, lifestyle changes, and specialized procedures.

How PH affects the lungs

The disease process in PH centers on the pulmonary vasculature. When arterial walls thicken, stiffen, constrict, or become blocked by clots, blood flow through the lungs is impeded and pressure builds. Increased pulmonary vascular resistance hinders oxygen uptake, so routine activities can feel more strenuous and breathing becomes more difficult. Underlying conditions—such as chronic lung disease, blood-clotting disorders, or connective tissue diseases—can trigger vessel remodeling. Identifying and treating these root causes is central to protecting lung function and guiding targeted therapies.

How the heart is involved

The right ventricle pumps blood into the pulmonary arteries and is therefore directly affected by rising pulmonary pressures. To overcome higher resistance it may thicken (hypertrophy), but over time this compensatory mechanism can fail, leading to right-sided heart dysfunction and symptoms like lightheadedness, chest pressure, and fluid retention. Monitoring heart size and performance is a key part of PH care. Cardiologists and pulmonologists work together to assess cardiac impact, adjust therapies that reduce pressure on the heart, and manage complications such as right heart failure.

Medical therapies for pulmonary hypertension

Treatment choices depend on the PH type, severity, and individual patient factors. Several drug classes are commonly used:

• Endothelin receptor antagonists: reduce vessel constriction and remodeling.
• Phosphodiesterase type 5 inhibitors: improve vasodilation and blood flow.
• Prostacyclin analogs and prostacyclin receptor agonists: potent vasodilators that also inhibit platelet aggregation.
• Soluble guanylate cyclase stimulators: enhance signaling pathways that relax pulmonary vessels.

Supportive measures often include diuretics to manage fluid buildup, supplemental oxygen for low blood oxygen levels, and anticoagulants in selected patients with clotting-related disease. Providers frequently balance benefits and side effects and may combine agents when a single medicine does not control symptoms adequately. Choice, dosing, and monitoring should be overseen by clinicians experienced in PH management.

When to see a doctor

Seek medical attention for persistent or worsening symptoms such as unexplained breathlessness, progressive fatigue, chest pain, fainting spells, or persistent swelling of the legs or abdomen. Your primary care clinician can perform initial evaluations and refer you to pulmonary or cardiac specialists. Diagnostic testing typically starts with echocardiography to estimate pulmonary pressures and assess right-heart function; definitive diagnosis and accurate hemodynamic measurements are obtained with right heart catheterization. If symptoms change or therapies need adjustment, timely consultation with a PH specialist or a center experienced in pulmonary hypertension is important.

Hospital and procedural treatments

Advanced or complex PH cases may require hospital-based interventions. Intravenous or inhaled prostacyclin therapies are often initiated and titrated inpatient to ensure safe dosing and monitor side effects. For chronic thromboembolic pulmonary hypertension (CTEPH), surgical pulmonary thromboendarterectomy can remove obstructive clots and dramatically reduce pulmonary pressures; where surgery is not feasible, balloon pulmonary angioplasty is another interventional option. In end-stage or refractory disease, lung transplantation or combined heart–lung transplant may be considered after careful evaluation.

Coordinated care and lifestyle measures

Optimal outcomes are most often achieved by a multidisciplinary team that includes your primary care clinician, pulmonologist, cardiologist, pharmacists, and rehabilitation professionals. Regular follow-up enables medication adjustments, monitoring of heart and lung function, and timely management of complications. Lifestyle actions that support treatment goals include smoking cessation, maintaining a heart-healthy diet, following supervised exercise or pulmonary rehabilitation programs, and controlling comorbid conditions like sleep apnea, thyroid disease, or connective tissue disorders.

Decisions about intensifying therapy or pursuing invasive procedures are individualized, weighing expected benefits, risks, and patient preferences. Early evaluation and referral to centers with PH expertise improve access to advanced treatments and clinical trials when appropriate. If you suspect symptoms or have a diagnosis of pulmonary hypertension, seek evaluation from experienced clinicians and ask about local specialized services and support resources.
