Why Pulmonary Hypertension Treatment Is Important
Left untreated, pulmonary hypertension (in some cases called pulmonary arterial hypertension) can cause significant damage to your heart and lungs that can only be improved with a lung transplant or heart-lung transplant. While there is no cure for most forms of pulmonary hypertension, early diagnosis and treatment can greatly improve your ability to live with the disease. One type of pulmonary hypertension -- chronic thromboembolic pulmonary hypertension (CTEPH), which is caused by old blood clots that have scarred the blood vessels leading to your lungs -- is potentially curable with surgery.
At Duke, our pulmonologists and cardiologists will review your health history and use sophisticated tools to confirm your diagnosis, identify what type of pulmonary hypertension you have, and help you determine what treatment will be most effective for you.
Tests for Pulmonary Hypertension
Blood tests that measure your blood oxygen levels, liver and kidney function, and other important indicators help us determine whether you have pulmonary hypertension and what treatments might be helpful if you do.
Chest Radiograph (X-ray)
Images of your lungs can reveal signs of pulmonary hypertension, including enlarged arteries and scarring.
An ultrasound probe is moved over the surface of your chest to capture moving images of your heart. This allows us to determine your heart’s chamber dimensions, shape, valve structures, and overall function. It also allows us to estimate the pressures inside the right chamber of your heart.
Small electrodes are placed on your skin to record your heart’s electrical impulses. This information helps us identify any abnormal rhythms, evaluate your heart function, and identify your risk for or prior heart muscle damage.
A narrow, flexible tube called a catheter is threaded through a blood vessel to your heart to diagnose pulmonary hypertension and determine whether it has caused damage to your heart muscle.
Lung Function Tests
These tests measure how much air your lungs can hold, how much air moves in and out of your lungs, and your lungs’ ability to exchange oxygen and carbon dioxide.
Nuclear Lung Scan
A nuclear lung scan creates an image of air and blood flow in your lungs. This can be used to identify blood clots in your lungs that may contribute to your condition.
Six-Minute Walk Test
This test evaluates how well your body tolerates exercise and can help determine how severe your pulmonary hypertension is.
