Who might be able to join this trial:
- People who have had a small heart monitor (called an implantable loop recorder with remote monitoring) surgically placed under their skin to track heart rhythms.
- People who have had a stroke within the last six months that doctors could not find a clear cause for, after a full medical workup — including brain scans, checks of the blood vessels, and heart monitoring over at least 24–72 hours — that ruled out common stroke causes such as blocked arteries, blood clots in the heart, irregular heart rhythms, and other specific conditions.
- People who have had a type of mini-stroke (called a TIA) within the last six months that caused specific symptoms such as difficulty speaking, ignoring one side of the body, or loss of vision on one side, and where no clear cause was found after a full standard evaluation.
- People aged 40 years or older.
- People who have at least one of the following risk factors: a heart risk score (called CHA2DS2VASc) of 4 or higher; short bursts of fast heart rhythm detected on monitoring; a left chamber of the heart measuring more than 45mm; or very slow blood flow out of a part of the heart called the left atrial appendage (confirm with trial site for exact measurements).
- People who have no medical reason preventing them from taking blood-thinning medication following the acute phase of their stroke.
- People who have given written consent to participate, either themselves or through an authorised caregiver.
