Stent showdown: which device heals arteries better after a heart attack?

NCT ID NCT03440801

Completed Disease control Sponsor: Tokorozawa Heart Center Source: ClinicalTrials.gov ↗

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study compared two drug-coated stents (Synergy and Xience) in 240 people who had a heart attack. The goal was to see which stent leads to better artery healing over three years, focusing on plaque buildup inside the stent. Both stents release a drug to prevent scarring, but one has a coating that dissolves over time.

What this could mean

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

Active substance: everolimus-eluting stents (Synergy and Xience)
What this could lead to: If one stent shows better long-term healing, it could reduce the risk of future heart problems after a heart attack.
What could go wrong: This is a small, completed study with 240 participants, so results may not apply to everyone. Stents carry risks like blood clots or re-narrowing.
