Could a simple blood test predict lung danger in heart defect patients?
NCT ID NCT02691689
First seen Jun 24, 2026 · Last updated Jun 24, 2026
Summary
This study is looking for genes that might explain why some people born with holes in their heart develop a serious lung condition called pulmonary arterial hypertension (PAH). Researchers will take blood samples from 21 patients with both a heart defect and PAH to search for known and new gene mutations. The goal is to find genetic clues that could help identify at-risk patients earlier, potentially leading to better prevention or treatment.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
genetic testing
What this could lead to
If successful, this could lead to a genetic screening test to identify heart defect patients at risk for pulmonary hypertension, enabling earlier monitoring or preventive care.
What could go wrong
This is a small pilot study with only 21 participants, so findings may not apply to everyone. It is exploratory and may not identify clear genetic links.
