First seen Jul 15, 2026 · Last updated Jul 21, 2026 · Updated 3 times

Summary

This trial tests whether a dietary supplement called Tertinat, containing epigallocatechin-3-gallate, can reduce major heart problems in people with atherosclerosis who have recently had bypass or stent surgery. Over two years, participants take either the supplement or a placebo alongside standard care. The study measures heart attacks, strokes, unstable angina, heart failure, and the need for repeat procedures.

What this could mean

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

Active substance
a dietary supplement called Tertinat, which contains epigallocatechin-3-gallate
What this could lead to
If it works, this could point toward a simple dietary supplement that lowers the risk of heart attacks, strokes, and repeat surgeries in people with hardened arteries.
What could go wrong
This is a Phase 2 trial, so it is still early. The supplement may not reduce heart events as hoped, and results may not apply to everyone with atherosclerosis.
