What does a pulmonary hypertension test measure?
There isn't just one test for pulmonary hypertension—your healthcare provider will likely use several tests to get a complete picture. Each test measures different aspects of your heart and lung function.
The gold standard test is right heart catheterization (RHC), which directly measures:
* Mean pulmonary arterial pressure (20 mm Hg or higher indicates PAH)
* Pulmonary artery systolic and diastolic pressure (heart contractions)
* Pulmonary vascular resistance (how blood flow is affected by artery diameter)
* Cardiac output (amount of blood pumping from the heart)
* Blood oxygen levels
Other common tests measure:
* Echocardiogram: Estimates pulmonary artery pressure and checks for heart enlargement or strain
* Electrocardiogram (ECG): Records your heart's electrical activity to detect abnormalities
* Six-minute walk test: Assesses how breathing and symptoms are affected during physical activity
* Blood tests: Look for risk factors like blood clotting disorders or anemia
* Chest X-ray: Shows heart size and pulmonary artery enlargement
* Lung function tests: Check for underlying lung diseases
These tests together help confirm PH, determine its severity, and identify what's causing it.
