Gut bacteria tweak may boost heart drug power

This study looks at whether an antibiotic called rifaximin can help the blood thinner ticagrelor work better in people who have had a heart attack or unstable angina. The idea is that unhealthy gut bacteria might make the drug less effective. The study will involve 50 adults who are already taking ticagrelor and have high platelet reactivity, meaning their blood is still too sticky. Researchers will give them rifaximin and check if their blood thinning improves.
