Skin blood flow test may predict heart danger in tough-to-treat high blood pressure
NCT ID NCT05464849
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study looked at 111 people to see if measuring blood flow in the skin can help assess cardiovascular risk in those with resistant hypertension (high blood pressure that doesn't respond to multiple drugs). Researchers used a laser device to check how well tiny blood vessels in the skin expand and contract. The goal was to see if these skin measurements could reveal hidden damage to organs and offer a non-invasive way to predict heart problems.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to a simple, non-invasive skin test to better predict heart risks in people with hard-to-treat high blood pressure.
- What could go wrong
- This is an observational study, not a treatment trial. It only measures blood flow, so it cannot directly improve health. Results may not apply to all patients.
