Summary

This study compares two ways to treat narrowed heart arteries: a drug-coated balloon (DCB) and a drug-eluting stent (DES). Researchers will measure how much the artery narrows again over time using ultrasound. About 256 adults with significant blockages will take part to see which method works better.

What this could mean

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

Active substance: Drug-coated balloon (DCB) and drug-eluting stent (DES)
What this could lead to: If successful, this could show that balloon angioplasty is as effective as stents for keeping heart arteries open, potentially offering a stent-free option.
What could go wrong: This is a small, early-phase study (256 participants) comparing two established treatments, so it may not lead to major changes in practice. Risks include artery re-narrowing or complications from the procedure.
