New blood thinner could make heart bypass safer during surgery
NCT ID NCT07514962
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing whether giving the blood thinner cangrelor through a vein during minimally invasive heart bypass surgery is safe and practical. The goal is to prevent dangerous blood clots while the patient is on the operating table. Researchers will compare 30 patients receiving cangrelor during surgery to similar patients from the past who received standard care with aspirin. The main focus is on whether cangrelor increases the risk of serious bleeding.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- cangrelor (a fast-acting blood thinner given through a vein)
- What this could lead to
- If successful, this could make minimally invasive heart bypass surgery safer by preventing blood clots during the procedure without increasing bleeding complications.
- What could go wrong
- This is a small, early-phase study with only 30 participants, so results may not apply to all patients. There is still a risk of bleeding or other complications despite careful monitoring.

Who is studied
The study population includes adult patients scheduled for minimally invasive direct coronary artery bypass (MIDCAB) surgery at Cardiocentro Ticino Institute, Lugano, Switzerland. Patients will be selected for either prospective cangrelor-guided MIDCAB or retrospective historical control MIDCAB under aspirin therapy. The population includes individuals with multivessel coronary artery disease requiring LIMA-LAD bypass, regardless of sex or comorbidities, who meet all inclusion and no exclusion criteria. Patients with planned concomitant PCI are excluded. This population represents real-world candidates for MIDCAB surgery under antiplatelet management protocols.
