Severe Pulmonary Hypertension: Recognizing the Key Symptoms and Diagnostic Approaches
Severe pulmonary hypertension presents with a range of symptoms that can significantly impact a person's quality of life. In the early stages, this condition may not produce noticeable symptoms, making it difficult to detect without proper medical evaluation.
Progression of Symptoms
As the condition progresses and pulmonary artery pressure continues to rise, patients may begin to experience more apparent symptoms. One of the most common signs is shortness of breath, particularly during physical activity. This occurs because the heart struggles to pump blood through the narrowed pulmonary arteries.
Critical Warning Signs
When pulmonary artery pressure exceeds 70mmHg, symptoms can become more severe. Individuals may experience episodes of dizziness or fainting, especially during exertion. These episodes are often caused by a temporary drop in blood pressure and reduced oxygen supply to the brain.
Additional Clinical Manifestations
Besides respiratory difficulties, patients might also suffer from:
- Chest pain or angina – due to reduced blood flow to the heart muscle
- Heart palpitations – caused by arrhythmias or irregular heartbeats
- Coughing up blood – a sign of pulmonary vascular congestion
- Peripheral edema – swelling in the legs and ankles indicating right heart failure
Associated Cardiac Changes
Chronic pressure overload can lead to structural changes in the heart, particularly affecting the right side. Right ventricular hypertrophy develops as the heart muscle thickens to cope with increased workload. This can eventually progress to right-sided heart failure, accompanied by complications such as tricuspid valve regurgitation.
Diagnostic Approaches
Accurate diagnosis is crucial for effective management. While echocardiography serves as a primary non-invasive screening tool, the gold standard for confirming pulmonary hypertension remains right heart catheterization. This procedure allows for direct measurement of pulmonary artery pressure and provides essential hemodynamic information for treatment planning.
