NCT ID NCT04471870
First seen Mar 10, 2026 · Last updated Jun 23, 2026 · Updated 16 times
Summary
This study followed over 1,000 people who had a heart attack and were given a quick-acting intravenous blood thinner called cangrelor during a procedure to open blocked arteries. Researchers wanted to see how often bleeding occurred when patients then switched to a different oral blood thinner. The goal was to gather real-world safety information, not to test a new treatment.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
cangrelor (intravenous blood thinner)
What this could lead to
If results are positive, it could confirm that switching from cangrelor to other blood thinners is safe in real-world practice.
What could go wrong
This is an observational study, not a controlled trial, so it cannot prove cause and effect. Bleeding risks may still vary by patient.
Conditions
