Stent showdown: which Drug-Coated device keeps heart arteries open longer?

NCT ID NCT00960648

Completed Disease control Sponsor: Seoul National University Hospital Source: ClinicalTrials.gov ↗

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This completed study looked at over 3000 people with coronary artery disease to compare two types of drug-eluting stents: everolimus-eluting (Xience/Promus) and sirolimus-eluting (Cypher). The goal was to see which one better prevents major heart problems like heart attacks or the need for repeat procedures. Researchers tracked patients for several years to measure safety and long-term effectiveness in real-world use.

What this could mean

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

Active substance: drug-eluting stents (everolimus-eluting stent and sirolimus-eluting stent)
What this could lead to: If successful, this could confirm that everolimus-eluting stents are as safe and effective as sirolimus-eluting stents for treating blocked heart arteries.
What could go wrong: This is a completed registry study, not a randomized trial, so results may be less definitive. Stents carry risks like blood clots or re-narrowing of the artery.
