Heart bypass patients: does a stronger blood thinner keep grafts working longer?

NCT ID NCT04783701

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looks at whether taking two blood thinners (ticagrelor plus aspirin) is better than aspirin alone for keeping bypass grafts open in people who had heart surgery after a heart attack. About 360 participants will be followed for 1 to 3 years, and their grafts will be checked with a special CT scan. The goal is to see if the stronger blood-thinning regimen reduces graft blockages.

What this could mean

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

Active substance

ticagrelor (antiplatelet drug) plus aspirin, compared to aspirin alone

What this could lead to

If it works, this could show that adding ticagrelor to aspirin helps keep bypass grafts open longer after heart surgery, potentially reducing the need for repeat procedures.

What could go wrong

This is a relatively small, early-phase study (360 participants) and results may not apply to all patients. The benefit of dual therapy must be weighed against a higher risk of bleeding.
