In the DaRe2THINK trial, we are testing if using blood thinning tablets earlier in patients with AF, before they develop other health conditions, can lower the risk of developing blood clots.

As part of the trial, your GP will have assigned you by random to one of two groups: either taking a blood thinning tablet now, or continuing your normal medications until you reach the age of 75 years (or 65 with other health conditions).

This extra study in 160 patients will help us to understand why some patients with AF develop dementia, and if blood thinners work by preventing damage to the brain or if they impact on blood vessels throughout the body. It is essential that we include patients in both groups in the trial, so we are asking all patients to join if they are within distance of the Queen Elizabeth Hospital in Birmingham where the scans will take place.
