Pulmonary Hypertension
What is Pulmonary Hypertension?
Pulmonary Hypertension is a serious condition characterized by high blood pressure in the arteries of the lungs, which increases strain on the heart and makes it harder to pump blood efficiently.
Quick Facts About Pulmonary Hypertension
- Affects the blood vessels of the lungs and the functioning of the heart
- Can gradually worsen over time if left untreated
- Requires early diagnosis and specialized evaluation for effective management
Types of Pulmonary Hypertension (WHO Classification)
The World Health Organization classifies Pulmonary Hypertension (PH) into five major groups based on the underlying cause and treatment approach:
| PH Group | Common Cause | Key Feature |
|---|---|---|
| Group 1 – Pulmonary Arterial Hypertension (PAH) | Idiopathic, hereditary, autoimmune disorders | Narrowing of the pulmonary arteries |
| Group 2 | Left-sided heart disease | Increased pressure due to backflow from the heart |
| Group 3 | Chronic lung diseases or low oxygen levels | Commonly associated with COPD and ILD |
| Group 4 – CTEPH | Chronic blood clots in the lungs | May be treatable with surgery in selected cases |
| Group 5 | Multifactorial or unclear causes | Linked to systemic or complex medical conditions |
Symptoms of Pulmonary Hypertension
You should consult a pulmonary hypertension specialist if you experience any of the following symptoms:
- Shortness of breath, especially during physical activity
- Persistent fatigue and weakness
- Chest pain, tightness, or pressure
- Dizziness or episodes of fainting
- Swelling in the legs, ankles, or feet
Important: Early symptoms of pulmonary hypertension can be mild and easily overlooked. Timely diagnosis and specialist evaluation are essential to prevent disease progression and improve long-term outcomes.
Causes of Pulmonary Hypertension
Pulmonary Hypertension can develop due to a variety of underlying medical conditions, including:
- Chronic lung diseases such as COPD and Interstitial Lung Disease (ILD)
- Heart diseases affecting the left side of the heart
- Blood clots in the lungs, also known as pulmonary embolism
- Sleep apnea and other sleep-related breathing disorders
- Autoimmune conditions such as lupus, scleroderma, and rheumatoid arthritis
Diagnosis by Pulmonary Hypertension
| Test | Purpose |
|---|---|
| 2D Echocardiography | Helps estimate pulmonary artery pressure and evaluate the functioning of the right side of the heart |
| HRCT Chest | Identifies underlying lung conditions such as ILD, COPD, or emphysema |
| Pulmonary Function Tests (PFTs) | Measures lung function, airflow, and breathing capacity |
| Blood Tests | Checks for autoimmune markers, BNP levels, thyroid disorders, and liver function abnormalities |
| Right Heart Catheterisation | Considered the gold standard for confirming pulmonary hypertension and guiding treatment decisions |
| V/Q Scan | Detects chronic blood clots associated with CTEPH |
An accurate diagnosis is essential for creating an effective and personalised treatment plan.
Treatment
Medications
- Vasodilators to improve blood flow
- Anticoagulants to reduce clotting risk
- Diuretics to manage fluid retention
- Oxygen therapy to support breathing and oxygen levels
Advanced Management
- Targeted pulmonary hypertension therapies
- Continuous monitoring and long-term disease management
Lifestyle & Supportive Care
- Activity and energy management guidance
- Dietary counselling and pulmonary rehabilitation support
A structured treatment approach can help improve symptoms, enhance quality of life, and slow disease progression.
FAQs – Pulmonary Hypertension Treatment
Pulmonary hypertension may not always be completely curable, but early diagnosis and appropriate treatment can help control symptoms, improve quality of life, and slow disease progression.
Pulmonary hypertension is a serious condition that can become life-threatening if left untreated. Timely evaluation and specialist care significantly improve long-term outcomes and disease management.
You should consult a pulmonary hypertension specialist if you experience unexplained shortness of breath, fatigue, chest discomfort, dizziness, or reduced exercise tolerance lasting for several weeks. Early medical attention can help prevent complications.
