Atrial fibrillation is a common, yet considerably under-recognised cause of ischaemic stroke. Detecting atrial fibrillation is of paramount importance in secondary prevention after stroke, as it is a definitive indication for anticoagulation (blood-thinning treatment). However, there is a basic lack of evidence about how best to screen patients after a stroke for atrial fibrillation. I led a systematic review and meta-analysis of the medical literature https://www.ahajournals.org/doi/pdf/10.1161/STROKEAHA.113.003433
to provide a best-evidence starting point for consensus recommendations for patient care and to inform future research.
