Longer duration of electrocardiographic monitoring after cryptogenic stroke is associated with a greater detection of AF .
BACKGROUND Atrial fibrillation ( AF ) is a major cause of stroke .
Although st and ard investigations after an event include electrocardiographic monitoring , the optimal duration to detect AF is unclear .
We performed a systematic review and meta- analysis to determine whether the duration of electrocardiographic monitoring after an ischemic event is related to the detection of AF .
Detection of Paroxysmal Atrial Fibrillation by 30-Day Event Monitoring in Cryptogenic Ischemic Stroke: The Stroke and Monitoring for PAF in Real Time (SMART) Registry
Background and Purpose — Patients with cryptogenic ischemic stroke may have undetected paroxysmal atrial fibrillation ( PAF ) . We established the Stroke and Monitoring for PAF in Real Time ( SMART ) Registry to determine the yield of 30-day outpatient PAF monitoring in cryptogenic ischemic stroke . Methods — The SMART Registry was a 3-year , prospect i ve multicenter registry of 239 patients with cryptogenic ischemic stroke undergoing 30-day outpatient autotriggered PAF detection in Kaiser Permanente Northern California . Results — In intention-to-monitor analysis , PAF was detected in 29 of 239 patients ( 12.1 % ; 95 % CI , 8.6%–16.9 % ) . After retrospective chart review was performed , a new diagnosis of PAF was confirmed in 26 of 236 patients ( 11.0 % ; 95 % CI , 7.6%–15.7 % ) . The majority of detected PAF events were asymptomatic ; only 6 of 98 recorded PAF events ( 6.1 % ) were patient-triggered or associated with symptoms . Conclusions — -Approximately 1 in every 9 patients with cryptogenic ischemic stroke was found to have new PAF within 30 days . Routine monitoring in this population should be strongly considered
