Blood markers may reveal hidden stroke risk in heart patients

NCT ID NCT02840201

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looked at 321 people with pacemakers or heart monitors who had short, symptomless episodes of atrial fibrillation (silent AF). Researchers measured certain proteins in the blood to see if they could predict who might later have a stroke or other heart problems. The goal is to better identify who needs blood-thinning medication.

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 help doctors identify which patients with silent atrial fibrillation are at highest risk for stroke and might benefit from blood thinners.

What could go wrong

This is a small, completed sub-study analyzing existing data, not a treatment trial. The findings may not change current practice without larger confirmatory studies.
