Can a blood vessel drug beat aspirin at preventing heart attacks in diabetes?

NCT ID NCT07719894

First seen Jul 22, 2026 · Last updated Jul 23, 2026 · Updated 1 time

Summary

This trial compares two blood-thinning drugs—aspirin and cilostazol—to see which one better prevents major heart and blood vessel events in people with type 2 diabetes who are already at high risk. About 1,200 participants will be randomly assigned to take one of the two medications daily. The study tracks heart attacks, strokes, hospitalizations, and related deaths over time to determine which drug offers stronger protection.

What this could mean

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

Active substance
cilostazol or aspirin
What this could lead to
If cilostazol proves more effective than aspirin, it could offer a better option for preventing heart attacks and strokes in people with type 2 diabetes.
What could go wrong
This is a phase 4 trial, so both drugs are already approved, but cilostazol may cause side effects like headache or palpitations, and it is unclear if it will outperform aspirin.
