Simple cheek swab could predict sudden cardiac death risk

NCT ID NCT04257994

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study explores whether a quick, painless cheek swab can spot protein changes linked to inherited heart conditions that cause sudden cardiac death in young people. Researchers will collect samples from 26 patients with arrhythmic disorders or family members at risk. If the test works, it could replace risky heart biopsies and help diagnose those at risk earlier.

Active substance
buccal smear sample
What this could lead to
If successful, this could provide a simple, painless cheek swab test to identify people at risk of sudden cardiac death without needing a heart biopsy.
What could go wrong
This is a small, early-stage study with only 26 participants, so results may not apply to everyone. The test is still experimental and not yet proven to reliably predict risk.
