Could a simple blood test predict lung danger in heart defect patients?
NCT ID NCT02691689
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study aims to find genes that make some people with congenital heart defects develop a serious lung condition called pulmonary arterial hypertension (PAH). Researchers will analyze DNA from blood samples of 21 patients with heart defects who also have PAH. The goal is to identify genetic mutations that could help predict and prevent PAH in the future.
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 (DNA sequencing on blood samples)
- What this could lead to
- If successful, this could lead to a genetic screening tool to identify heart defect patients at risk for pulmonary hypertension, enabling earlier monitoring or prevention.
- 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.
