What is the risk of ischemic stroke associated with a 1-h threshold of AHRE burden?
The risk of ischemic stroke associated with a 1-h threshold of AHRE burden was found to be 2.11 (95% CI, 1.22-3.64; P .008) according to a re-analysis of the ASSERT study and the Stroke Prevention Strategies Based on Atrial Fibrillation Information From Implanted Devices [SOS AF] project. This risk was part of an analysis which found that 43% of an unselected cohort of patients with implanted devices experienced at least one day with at least 5 minutes of AHRE burden during a median follow-up of 24 months.
