New stent design tested in thousands with complex heart blockages

NCT ID NCT05705973

First seen Jul 10, 2026 · Last updated Jul 10, 2026

Summary

This study follows about 3000 people with complex coronary artery disease who receive the Ultimaster Nagomi stent, a device that slowly releases a drug to keep arteries open. The goal is to see how often the stent fails—meaning heart-related death, heart attack, or need for another procedure—in real-world, challenging cases. Researchers are tracking success rates and complications to better understand the stent's performance outside of controlled trials.

What this could mean

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

Active substance
sirolimus-eluting coronary stent
What this could lead to
If successful, this could confirm that the Ultimaster Nagomi stent is safe and effective for people with complex coronary artery blockages.
What could go wrong
This is an observational follow-up, not a randomized trial, so results may be less definitive. Stents carry risks like blood clots or re-narrowing of the artery.
