Tiny particles in blood may reveal heart transplant rejection without a biopsy

NCT ID NCT07673536

First seen Jun 29, 2026 · Last updated Jul 02, 2026 · Updated 3 times

Summary

This study looks at whether proteins carried by tiny particles called extracellular vesicles in the blood can signal when a heart transplant is being rejected. Researchers will track 30 heart transplant patients over 15 months, comparing protein patterns in those with and without rejection. The goal is to find a reliable, non-invasive way to diagnose rejection earlier than current methods allow.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

extracellular vesicle protein profiling (diagnostic test)

What this could lead to

If successful, this could lead to a simple blood test to detect heart transplant rejection early, reducing the need for invasive heart biopsies.

What could go wrong

This is a small, early-stage study (30 participants) focused on finding protein patterns, not yet proving the test works in practice. The identified markers may not be reliable enough for routine use.
