Heart attack patients may ditch aspirin sooner with new drug cocktail
NCT ID NCT06543082
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests if taking colchicine (an anti-inflammatory drug) along with a single blood thinner (ticagrelor) right after a heart attack stent is safe and works well. About 490 adults who had a heart attack and received a specific type of stent will participate. The goal is to see if this approach reduces heart-related problems and bleeding risks compared to standard longer-term dual therapy.
