BACKGROUND Cryptogenic stroke is a stroke for which no cause is identified after st and ard diagnostic tests .
Long-term implantable cardiac monitors may be better at diagnosing atrial fibrillation and provide an opportunity to reduce the risk of stroke recurrence with anticoagulants .
OBJECTIVES The objectives were to assess the diagnostic test accuracy , clinical effectiveness and cost-effectiveness of three implantable monitors [ BioMonitor 2-AF ™ ( Biotronik SE & Co. KG , Berlin , Germany ) , Confirm Rx ™ ( Abbott Laboratories , Lake Bluff , IL , USA ) and Reveal LINQ ™ ( Medtronic plc , Minneapolis , MN , USA ) ] in patients who have had a cryptogenic stroke and for whom no atrial fibrillation is detected after 24 hours of external electrocardiographic monitoring .
Detection of atrial fibrillation in patients with embolic stroke of undetermined source by prolonged monitoring with implantable loop recorders.
Recently , the clinical entity embolic stroke of undetermined source ( ESUS ) has been defined for patients with ischemic strokes , where neither a cardioembolic nor a non-cardiac source can be detected . These patients may suffer from asymptomatic atrial fibrillation ( AF ) , terminating spontaneously and thus eluding detection . Implantable loop recorders ( ILR ) with automatic AF detection algorithms can detect short-lasting , sub clinical AF . The aim of this study was to prospect ively assess and predict AF detection in patients with ESUS using ILR with daily remote interrogation . Patients with acute ESUS received an ILR , were seen every 6 months and additionally interrogated their ILR daily using remote monitoring . The incidence of AF detection was assessed and parameters which might predict AF detection ( clinical and from magnetic resonance tomography ) were analysed . ILR implantation was performed in 123 patients on average 20 days after stroke . During a mean follow-up of 12.7±5.5 months , AF was documented and manually confirmed in 29 of 123 patients ( 23.6 % ) . First AF detection occurred on average after 3.6±3.4 months of monitoring . Patients with AF were on average older , had a higher CHA2DS2-VASc score and more often cerebral microangiopathy . In conclusion , AF can be documented in approximately 25 % of patients with the diagnosis of ESUS after careful work-up within a year of monitoring by an ILR and daily remote interrogation . This had important therapeutic consequences ( initiation of anticoagulation for secondary stroke prevention ) in these patients
