What tests are used to diagnose pulmonary arterial hypertension?

ANSWER

Your doctor may order tests, including:

Your doctor may also do blood tests to check for HIV and conditions like rheumatoid arthritis or lupus.

  • Echocardiogram: This ultrasound picture of the beating heart can check blood pressure in the pulmonary arteries.
  • CT scan: This can show enlarged pulmonary arteries. A CT scan can also spot other problems in the lungs that could cause shortness of breath.
  • Ventilation-perfusion scan (V/Q scan): This test can help find blood clots that can cause high blood pressure in the lungs.
  • Electrocardiogram (EKG or ECG): An EKG traces the heart's activity and can show whether the right side of the heart is under strain. That's a warning sign of pulmonary hypertension.
  • Chest X-ray: An X-ray can show if your arteries or heart are enlarged. Chest X-rays can help find other lung or heart conditions that may be causing the problems.
  • Exercise testing: Your doctor may want you to run on a treadmill or ride a stationary bike while you are hooked up to a monitor, so he or she can see any changes in your oxygen levels, heart function, lung pressure, or other things.
