Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Pulmonary hypertension (PH) is a condition in which high blood pressure develops in the lungs and right side of the heart. People with PH suffer from shortness of breath, chest pain, heart failure, heart rhythm problems, and fainting. PH is diagnosed using a test called a cardiac catheterization where blood pressure is measured directly using a tube placed in the right side of the heart and lung arteries. Because a cardiac catheterization is invasive, researchers are investigating ways to diagnose PH using imaging tests that are not invasive. The study will evaluate whether or not a magnetic resonance image (MRI) of the heart, and blood tests can detect PH.
