What is Pulmonary Hypertension?

Pulmonary Hypertension (PH) is a group of conditions in which blood pressure in the pulmonary arteries is abnormally high. This increases the workload on the right side of the heart and, if persistent, can lead to right-heart enlargement and failure.

PH is classified into five groups based on its underlying cause:

  • Group 1 - Pulmonary Arterial Hypertension (PAH): Affects the pulmonary arteries and may be idiopathic, inherited, drug-related, or associated with conditions such as connective tissue disease or congenital heart disease.
  • Group 2 - PH Due to Left Heart Disease: Caused by conditions such as heart failure or left-sided valve disease.
  • Group 3 - PH Due to Lung Disease or Hypoxia: Associated with conditions such as COPD, interstitial lung disease, or chronic low oxygen levels.
  • Group 4 - PH Due to Pulmonary Artery Obstructions: Includes chronic thromboembolic pulmonary hypertension (CTEPH).
  • Group 5 - PH With Unclear or Multifactorial Causes: Includes conditions with multiple or less clearly understood mechanisms.

What is the Importance of Timely Treatment?

Timely diagnosis allows clinicians to identify the underlying type of PH, assess disease severity and right-heart function, and select appropriate treatment. Severe or rapidly worsening breathlessness, chest pain, fainting, blue or grey lips, or sudden breathlessness with chest pain should receive urgent medical assessment.

What are the Common Symptoms of Pulmonary Hypertension?

  • Shortness of Breath: Breathlessness may start during exercise and become more frequent as the condition progresses.
  • Fatigue and Weakness: Reduced exercise capacity and impaired blood flow can cause persistent tiredness or weakness.
  • Chest Discomfort or Pain: Some patients experience chest pressure or pain, particularly during exertion.
  • Dizziness or Fainting: Reduced ability of the cardiovascular system to increase blood flow during activity may cause lightheadedness or syncope.
  • Swelling of the Legs and Feet: Right-sided heart strain can contribute to fluid accumulation in the lower limbs.
  • Abdominal or Facial Swelling: Fluid retention may sometimes cause abdominal swelling or other signs of congestion.
  • Rapid or Irregular Heartbeat: Some patients may have palpitations.
  • Cough or Wheezing: Coughing or wheezing may occur, particularly when PH is associated with underlying lung disease.
  • Coughing Up Blood: Hemoptysis can occur in some patients and requires medical evaluation.

Causes and Risk Factors of Pulmonary Hypertension

Causes

  • Pulmonary Arterial Disease: Abnormal narrowing or remodelling of the pulmonary arteries can cause Group 1 PAH.
  • Left-Sided Heart Disease: Heart failure, cardiomyopathy, and left-sided valvular disease can increase pressure in the pulmonary circulation.
  • Chronic Lung Disease: COPD, interstitial lung disease, emphysema, and other chronic respiratory disorders may contribute to PH.
  • Chronic Hypoxia: Long-term low oxygen levels can contribute to pulmonary vascular changes.
  • Chronic Blood Clots: Persistent obstruction of pulmonary arteries can cause CTEPH.
  • Congenital Heart Disease: Certain congenital heart defects can increase pulmonary blood flow or pressure.
  • Connective Tissue Diseases: Conditions such as systemic sclerosis and other connective tissue disorders may be associated with PAH.
  • Liver and Portal Circulation Disorders: Portal hypertension and certain liver diseases can be associated with PAH.
  • HIV Infection: HIV infection is associated with an increased risk of pulmonary arterial hypertension.
  • Blood and Metabolic Disorders: Certain haematological, metabolic, or systemic conditions can contribute to PH.
  • Genetic Factors: Some forms of PAH have an inherited component.

Risk Factors

  • Family history of pulmonary hypertension
  • Certain genetic disorders
  • Congenital heart disease
  • Connective tissue diseases
  • Chronic lung disease
  • Sleep-disordered breathing
  • Previous or recurrent pulmonary blood clots
  • Liver disease or portal hypertension
  • HIV infection
  • Certain medications or toxins
  • Smoking
  • Increasing age
  • Conditions associated with chronic low oxygen levels

Latest Research and Technologies in the Treatment of Pulmonary Hypertension in Turkey

  • Advances in pulmonary hypertension care include improved echocardiography, right-heart catheterisation, cardiac MRI, and ventilation/perfusion (V/Q) scanning for accurate diagnosis and assessment. Treatment increasingly uses targeted combination therapies for eligible patients with pulmonary arterial hypertension (PAH). For chronic thromboembolic pulmonary hypertension (CTEPH), pulmonary endarterectomy, balloon pulmonary angioplasty, and targeted medical therapy may be considered according to the patient's condition. Availability of these specialised services varies by hospital and centre.

Treatment options for Pulmonary Hypertension

PDA Closure : A catheter-based or surgical procedure may be considered when a persistent ductus arteriosus is causing clinically significant problems, and closure is appropriate. Specialist haemodynamic assessment is essential because closing a shunt can be harmful in some patients with advanced pulmonary vascular disease.


Cost Start From 5500Explore Options

Guideline-Directed Medical Therapy (GDMT): The prognostic "four-pillar" medication regimen consisting of an ARNI/ACE inhibitor, an evidence-based beta-blocker, an SGLT2 inhibitor, and a mineralocorticoid receptor antagonist to stop ventricular remodelling.

Loop Diuretic Therapy: Diuretics may be prescribed to reduce fluid retention, leg swelling, and abdominal congestion in patients with right-sided heart failure. Treatment requires monitoring of kidney function, blood pressure, and electrolytes.

Mechanical Circulatory Support (LVAD Implantation) : The surgical placement of an implantable mechanical heart pump to assist or completely take over the workload of a failing left ventricle in advanced disease stages.

Orthotopic Heart Transplantation : The definitive, terminal surgical option where the patient's severely damaged, failing heart is completely removed and replaced with a healthy donor heart.

  • Clinical assessment:
    • Medical History: Assessment includes breathlessness, exercise tolerance, chest pain, dizziness, fainting, swelling, previous blood clots, heart and lung diseases, connective tissue disorders, medications, family history, and relevant exposures.
    • Physical Examination: Clinicians may assess oxygen saturation, heart sounds, lung sounds, neck veins, peripheral swelling, liver enlargement, blood pressure, heart rate, and other signs of right-heart strain.
    • Electrocardiogram (ECG): May identify right-heart strain, rhythm abnormalities, or other cardiac findings.
    • Blood Tests: Tests may assess blood counts, kidney and liver function, thyroid function, iron status, biomarkers of cardiac stress, and possible associated diseases.
    • BNP or NT-proBNP: These biomarkers may help assess cardiac strain and are also useful for risk assessment and monitoring in appropriate patients.
    • Pulmonary Function Tests: Spirometry, lung volumes, and diffusion capacity can help identify underlying lung disease.
    • Oxygen Assessment: Pulse oximetry and, when indicated, arterial blood gas testing can evaluate oxygenation.
  • Imaging Tests:
    • Transthoracic Echocardiography: A key non-invasive test for assessing right-heart structure and function and estimating the probability of pulmonary hypertension.
    • Transesophageal Echocardiography: May provide additional cardiac and structural information in selected patients.
    • Chest X-Ray: Can help identify changes involving the heart, lungs, or pulmonary arteries and may support evaluation of other causes of symptoms.
    • Ventilation/Perfusion (V/Q) Scan: Particularly useful for evaluating chronic thromboembolic disease.
    • CT Pulmonary Angiography: Provides detailed images of pulmonary arteries and surrounding structures and may help identify thromboembolic or other causes.
    • High-Resolution CT: May be used to evaluate interstitial lung disease, emphysema, or other lung abnormalities.
    • Cardiac MRI: Provides detailed assessment of right- and left-heart structure and function and may be useful for selected patients.
    • Right-Heart Catheterisation: Directly measures pulmonary pressures and other haemodynamic parameters and is an important test to confirm and characterise PH when clinically indicated.

MediRehab (a chain of Rehab centres, part of MediGence) provides comprehensive tele-rehabilitation services designed to support Pulmonary Hypertension patients in Turkey. These services include:

  • Supervised Exercise Training: Selected stable patients may benefit from supervised, individually prescribed exercise programmes.
  • Pulmonary Rehabilitation: Rehabilitation can help improve exercise capacity, physical function, and confidence in appropriate patients.
  • Breathing and Energy-Conservation Techniques: Patients may learn techniques to manage breathlessness and conserve energy during daily activities.
  • Gradual Activity Progression: Increase exercise intensity according to symptoms, functional capacity, oxygen levels, and specialist guidance.
  • Oxygen Management: Patients requiring supplemental oxygen should use it as prescribed, particularly during activity or sleep when indicated.
  • Long-Term Follow-Up: Regular assessment of symptoms, exercise capacity, right-heart function, oxygenation, and treatment response is important.
  • Medication for Pulmonary Hypertension depends on its group, severity, and underlying cause. Group 1 PAH: antagonists, inhibitors, stimulators, analogues, receptor agonists, and calcium channel blockers in selected patients. Group 2: heart-failure medicines, diuretics, and valve-directed treatments. Group 3: oxygen therapy, inhaled therapies, and medicines for the underlying lung disease. Group 4: anticoagulants, pulmonary vasodilators, and selected targeted therapies. Group 5: treatment of the underlying condition, with supportive medicines when required.

Frequently Asked Questions

Pulmonary Hypertension is generally a chronic condition, so recovery depends on its underlying cause and whether the cause can be treated or reversed. Some patients experience improvement over weeks or months after starting appropriate treatment, while others require long-term disease management. Recovery after procedures such as pulmonary endarterectomy or balloon pulmonary angioplasty varies according to disease severity and overall health.

Many people with stable Pulmonary Hypertension can walk and participate in appropriately supervised physical activity. However, exercise tolerance varies significantly. A specialist may recommend an individualised exercise or pulmonary rehabilitation programme based on symptoms, oxygen levels, right-heart function, and disease severity. Severe breathlessness, chest pain, dizziness, or fainting during activity requires medical assessment.

Many advanced cardiac and respiratory centres in Turkey provide echocardiography, right-heart catheterisation, CT and MRI, V/Q scanning, pulmonary function testing, targeted PH medicines, and specialised procedures such as pulmonary endarterectomy or balloon pulmonary angioplasty where available.

Many major Turkish hospitals have international patient departments that assist overseas patients with medical records, appointments, treatment coordination, accommodation, interpretation where available, and follow-up arrangements.

Consider a centre with clinicians experienced in Pulmonary Hypertension, access to comprehensive haemodynamic and imaging evaluation, appropriate targeted medicines, and multidisciplinary cardiac and respiratory care. For suspected CTEPH, consider whether the centre can evaluate operability and provide or coordinate pulmonary endarterectomy and balloon pulmonary angioplasty when appropriate.

The success rate for Pulmonary Hypertension treatment varies because PH includes several different disease groups with different causes, severity levels, and treatment approaches. Outcomes depend on the PH type, haemodynamic severity, right-heart function, underlying disease, response to treatment, and whether a correctable cause such as chronic thromboembolic obstruction is present. A specialist can discuss expected outcomes based on the individual diagnosis.

Many specialised cardiac and respiratory centres in Turkey have cardiologists, pulmonologists, pulmonary vascular specialists, and cardiothoracic surgeons involved in the diagnosis and management of Pulmonary Hypertension. Experience varies between centres, so patients should review the team's specific expertise and available PH services.

Risks depend on the underlying PH group and treatment. Medicines can cause side effects such as low blood pressure, fluid retention, bleeding, liver-related effects, or other drug-specific complications. Catheter-based procedures can involve bleeding, vascular injury, infection, contrast-related complications, or rhythm disturbances. Pulmonary endarterectomy is major surgery with risks that include bleeding, infection, reperfusion-related complications, and other cardiopulmonary complications. The treating team should discuss procedure-specific risks before treatment.

Pulmonary Hypertension is a cardiovascular and pulmonary condition, not an injury. If you develop sudden or severe breathlessness, chest pain, fainting, coughing up significant amounts of blood, blue or grey lips, or sudden worsening of symptoms, seek emergency medical care. Sudden breathlessness with chest pain can also indicate a pulmonary embolism or another medical emergency.

Pulmonary Hypertension does not usually cause skeletal deformities. However, advanced disease can lead to persistent limitations in exercise capacity, right-sided heart failure, fluid retention, and reduced physical function. Treating the underlying cause and controlling pulmonary pressures can help reduce complications.

Yes. Breathlessness, fatigue, reduced exercise tolerance, chest discomfort, dizziness, medication requirements, and restrictions on daily activities can affect physical, emotional, and social well-being. Appropriate treatment, rehabilitation, symptom management, and regular specialist follow-up can help patients maintain functional ability and quality of life.

Untreated or inadequately controlled PH can progressively increase the workload on the right side of the heart and may lead to right-heart failure. Other complications can include arrhythmias, fluid accumulation, reduced oxygenation, blood clots, liver dysfunction, and other organ complications. The severity and progression depend on the underlying type and cause of PH.

Pulmonary Hypertension cannot always be prevented because some forms are inherited or associated with conditions that cannot be completely avoided. Risk may be reduced by avoiding smoking and harmful drug or toxin exposure, treating heart and lung diseases appropriately, preventing and managing blood clots when medically indicated, maintaining a healthy weight and activity level, and seeking evaluation for persistent breathlessness or other concerning symptoms. People with known risk conditions may require appropriate screening or monitoring.

Risk varies substantially by the type of Pulmonary Hypertension. It can occur at any age and may be associated with congenital heart disease, connective tissue disease, chronic lung disease, chronic blood clots, liver disease, HIV infection, genetic factors, and certain medications or toxins. Some forms, particularly certain types of PAH, are more common in women.
