Key Takeaways
- Pulmonary hypertension is a serious form of high blood pressure that affects the arteries in the lungs and the right side of the heart, often causing symptoms like shortness of breath and fatigue.
- Most patients need a combination of targeted medications, oxygen support when indicated, and ongoing monitoring to slow disease progression.
- Advanced therapies such as IV prostacyclins, balloon pulmonary angioplasty, or lung transplant evaluation may be considered for severe or treatment-resistant cases.
- Lifestyle adjustments, including a low-sodium diet, supervised activity, and vaccinations against respiratory infections, play a major role in long-term quality of life.
- Altoona Lung Specialists is a leading provider of pulmonary hypertension care in Central Pennsylvania, offering personalized treatment plans built around each patient. To get started, request an appointment today.
What Is Pulmonary Hypertension?
Pulmonary hypertension (PH) is a type of high blood pressure that affects the arteries running between the lungs and the right side of the heart. When the small vessels in the lungs become narrowed, stiff, or blocked, the heart has to work harder to push blood through them. Over time, that extra strain can damage the right ventricle and lead to heart failure.
According to the National Heart, Lung, and Blood Institute, about 1% of people globally have pulmonary hypertension, and in the United States, the most common form is linked to left-sided heart disease, such as left heart failure.
The Five Groups of Pulmonary Hypertension
Pulmonary hypertension is classified into five groups based on the underlying cause. Identifying the correct group is critical because treatment differs significantly between them.
| Group | Underlying Cause | Common Examples |
|---|---|---|
| Group 1 | Pulmonary Arterial Hypertension (PAH) | Idiopathic PAH, connective tissue disease, and congenital heart defects |
| Group 2 | Left-Sided Heart Disease | Left heart failure, valve disease |
| Group 3 | Lung Disease or Low Oxygen | COPD, pulmonary fibrosis, sleep apnea |
| Group 4 | Pulmonary Artery Obstructions | Chronic thromboembolic PH (CTEPH) |
| Group 5 | Unknown or Multiple Causes | Sarcoidosis, sickle cell disease, metabolic disorders |
Symptoms of Pulmonary Hypertension
Symptoms often appear gradually, which is one reason PH can be missed in its early stages. Common signs include:
- Shortness of breath during activity, and later at rest
- Persistent fatigue
- Dizziness or fainting
- Chest pressure or pain
- Swelling in the ankles, legs, or abdomen
- Heart palpitations or a rapid heartbeat
- Bluish color in the lips and skin
Many of these symptoms overlap with other heart and lung conditions, which is why patients experiencing ongoing shortness of breath should see a pulmonologist for a complete evaluation.
How Pulmonary Hypertension Diagnosis Works
A timely, accurate pulmonary hypertension diagnosis is the foundation of effective treatment. Altoona Lung Specialists uses a combination of tools to confirm PH, classify the type, and measure severity.
The diagnostic workup typically includes:
- Echocardiogram: A non-invasive ultrasound that screens for elevated pressures in the lungs and evaluates heart function.
- Pulmonary function tests: Used to check whether an underlying lung condition like COPD or pulmonary fibrosis is contributing to PH.
- Six-minute walk test: Measures functional capacity and helps track changes over time.
- CT or VQ scans: Used to look for blood clots, scarring, or structural abnormalities.
- Right heart catheterization: The gold-standard test that directly measures the pressure in the pulmonary arteries. According to the American Lung Association, this test is essential for confirming a PH diagnosis.
Medications Commonly Used to Manage Pulmonary Hypertension
Medications for pulmonary hypertension target the narrowed vessels, the strain on the heart, or the underlying disease driving the condition. Many patients take more than one medication, and the right combination depends on the PH group, severity, and how a patient responds to therapy.
| Medication Class | How It Helps | Common Examples |
|---|---|---|
| Phosphodiesterase-5 (PDE-5) Inhibitors | Relax the pulmonary arteries to improve blood flow | Sildenafil, Tadalafil |
| Endothelin Receptor Antagonists (ERAs) | Block a vessel-narrowing protein in the lungs | Bosentan, Ambrisentan, Macitentan |
| Prostacyclin Analogs | Widen pulmonary arteries and reduce clotting | Epoprostenol, Treprostinil, Iloprost |
| Soluble Guanylate Cyclase (sGC) Stimulators | Boost natural vessel-relaxing signals | Riociguat |
| Calcium Channel Blockers | Lower pressure in select responsive patients | Diltiazem, Nifedipine |
| Diuretics | Reduce fluid buildup and swelling | Furosemide, Spironolactone |
| Anticoagulants | Lower clot risk in certain PH types, including CTEPH | Warfarin |
Drug therapy is most effective when paired with regular follow-up. The pulmonary team adjusts doses, monitors side effects, and watches closely for any change in how a patient feels day to day.
Advanced Therapies for Severe Pulmonary Hypertension
When medications alone are not enough, several advanced options can help patients with more severe disease.
Continuous IV or Subcutaneous Prostacyclins
For high-risk Group 1 PAH patients, continuous infusion of prostacyclin medications such as epoprostenol or treprostinil can dramatically improve symptoms and survival. These therapies require a small pump and careful patient education.
Oxygen Therapy
Supplemental oxygen helps patients whose blood oxygen levels drop with activity or at rest. Even modest oxygen use can ease the workload on the heart and reduce shortness of breath.
Balloon Pulmonary Angioplasty (BPA) and Pulmonary Thromboendarterectomy (PTE)
For patients with CTEPH (Group 4), BPA or surgical removal of blood clots in the pulmonary arteries can offer significant improvement and, in some cases, a potential cure.
Atrial Septostomy and Lung Transplant
In rare cases, patients with end-stage PH may be referred for atrial septostomy (a procedure that creates a small opening between the heart's upper chambers) or lung transplant evaluation. These options are typically reserved for select patients at expert centers.
Lifestyle Changes That Support Treatment
Treatment is most effective when paired with healthy day-to-day habits. Patients with pulmonary hypertension often benefit from:
- A heart-healthy, low-sodium diet to reduce fluid retention and ease the heart's workload
- Supervised, gentle exercise such as walking or cardiac rehab to improve stamina without overexertion
- Vaccinations against influenza, COVID-19, and pneumococcal pneumonia to prevent respiratory infections
- Avoiding high altitudes and unpressurized air travel without consulting a pulmonologist
- Stopping smoking and avoiding secondhand smoke
- Family planning conversations, since pregnancy carries significant risk for women with PAH
The team at Altoona Lung Specialists works with each patient to build a plan that respects their lifestyle and supports long-term lung and heart health.

Frequently Asked Questions
What is pulmonary hypertension in simple terms?
Pulmonary hypertension is high blood pressure in the arteries that connect the lungs and the heart. The narrowed vessels force the heart to work harder, which can lead to symptoms like breathlessness, fatigue, and swelling, and over time, heart strain.
How is pulmonary hypertension diagnosed?
A pulmonary hypertension diagnosis usually starts with an echocardiogram and pulmonary function testing. To confirm the condition and classify its type, doctors perform a right heart catheterization, which is the most accurate way to measure pressure in the pulmonary arteries.
What medications are used for pulmonary hypertension?
Common medications for pulmonary hypertension include PDE-5 inhibitors (such as sildenafil), endothelin receptor antagonists (such as macitentan), prostacyclin analogs, sGC stimulators, calcium channel blockers in select patients, diuretics, and, in some PH types, anticoagulants. The right combination depends on which group of PH a patient has.
Can pulmonary hypertension be cured?
There is no universal cure for pulmonary hypertension, but treatment can significantly improve symptoms, slow progression, and extend life. For patients with chronic thromboembolic PH (Group 4), surgical removal of clots in the pulmonary arteries can sometimes resolve the condition.
