Heart stent study reveals long-term narrowing risks after complex artery procedure
NCT ID NCT07473596
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study looked at 294 patients who had a procedure to open a completely blocked heart artery (CTO PCI) with a drug-coated stent. Researchers wanted to know how often the stents narrowed again over at least three years and what factors increased that risk. The study used CT scans and sometimes invasive angiography to check the stents.
