Screening for atrial fibrillation in high-risk populations could contribute to the prevention of cardioembolic stroke. Randomized trials of atrial fibrillation screening are directionally favourable but underpowered for stroke risk assessment; nevertheless, meta-analysis results are encouraging. Consumer-facing wearable devices can detect unknown atrial fibrillation at scale, although they are mostly used by individuals at low risk of stroke.
