Pulmonary hypertension

What is pulmonary hypertension?
Pulmonary hypertension (PH) is a progressive and potentially life-threatening condition characterised by high blood pressure in the arteries of the lungs. In PH, the walls of the pulmonary arteries become narrowed, thickened, or stiff, leading to increased resistance to blood flow through the lungs.

This elevated pressure strains the right side of the heart, which may eventually result in heart failure if left untreated.

 

WHAT ARE THE SIGNS?

The signs and symptoms of pulmonary hypertension vary depending on the severity of the condition. Patients may experience:

  1. Shortness of breath, especially during physical activity.
  2. Fatigue or weakness.
  3. Chest pain or pressure.
  4. Swelling in the ankles, legs, or abdomen.
  5. Bluish lips or skin (cyanosis).
  6. Rapid heartbeat (palpitations).
  7. Dizziness or fainting spells.

These symptoms may significantly impact a patient's quality of life and may worsen over time without appropriate management.

HOW IS PULMONARY HYPERTENSION DIAGNOSED?

Dr Muhammed Zaid Hoosen employs a comprehensive approach to diagnose pulmonary hypertension accurately. The diagnostic process may involve:

  1. Medical history and physical examination: Dr Hoosen meticulously reviews the patient's medical history and conducts a comprehensive physical examination to evaluate symptoms and signs indicative of pulmonary hypertension (PH).
  2. Diagnostic procedures: Various tests are utilised to confirm the diagnosis and gauge the severity of PH, including:
    • Echocardiogram: This non-invasive examination employs sound waves to generate images of the heart, assessing its structure and function.
    • Right heart catheterisation: In this procedure, a catheter is inserted into the pulmonary artery to measure blood pressure and evaluate pulmonary circulation resistance.
    • Pulmonary function tests: These assessments analyse lung function, aiding in the exclusion of other lung conditions that may mimic PH.
    • Blood tests: Biomarkers such as brain natriuretic peptide (BNP) or N-terminal pro-B-type natriuretic peptide (NT-proBNP) may be measured to evaluate heart function.
  2. Imaging studies: Chest X-rays, CT scans, or MRI scans may be conducted to scrutinise the structure and function of the heart and lungs, identifying any underlying causes of PH.

HOW DO YOU TREAT PULMONARY HYPERTENSION?

Dr Hoosen develops individualised treatment plans based on the severity of PH, its underlying cause, and the patient's overall health. Treatment strategies may include:

  1. Medications: Several classes of medications are used to manage PH and improve symptoms, including vasodilators, endothelin receptor antagonists, phosphodiesterase-5 inhibitors, prostacyclin analogs and diuretics
  2. Oxygen Therapy: Additional oxygen may be recommended to enhance blood oxygen levels and relieve symptoms of hypoxemia (low oxygen levels).
  3. Lifestyle Adjustments: Dr Hoosen underscores the significance of lifestyle alterations, including maintaining a healthy weight, engaging in physical activity within recommended guidelines, abstaining from smoking and exposure to second-hand smoke, and effectively managing underlying health issues such as sleep apnea or heart disease.
  4. Surgical Options: In certain instances, surgical interventions like atrial septostomy or lung transplantation may be contemplated for patients with severe PH unresponsive to medical treatment.

FAQ

1How often should patients with pulmonary hypertension see their healthcare provider?
Patients with pulmonary hypertension should follow up regularly with their healthcare provider, as directed. The frequency of follow-up visits varies depending on the severity of the condition and the treatment plan. It is essential to adhere to the recommended schedule to monitor the effectiveness of treatment and address any changes in symptoms.
2What complications can arise from untreated pulmonary hypertension?
Untreated pulmonary hypertension can lead to severe complications, including right-sided heart failure, arrhythmias, blood clots in the lungs (pulmonary embolism), and even death.
3Is pulmonary hypertension hereditary?
While certain types of pulmonary hypertension may have a genetic basis, not all instances are hereditary. It's crucial to communicate one's family medical history with a healthcare professional to ascertain potential risk factors associated with developing pulmonary hypertension.
