P3348Prevention of stroke in intracerebral haemorrhage survivors with atrial fibrillation (PRESTIGE-AF): a retrospective cohort study

Abstract Background Atrial fibrillation (AF) patients surviving an intracerebral haemorrhage (ICH) present a clinical challenge. The PRESTIGE-AF trial is an ongoing trial designed to investigate the optimal stroke prevention strategy in AF patients who have suffered an ICH. Purpose To describe baseline clinical characteristics of a study population similar to the expected PRESTIGE-AF trial. Methods The patient population was identified from the Danish Stroke Registry, linked with additional registries to obtain information on comorbidities and medication. Specific incl/excl criteria from the PRESTIGE-AF trial were applied, including indication for OAC treatment due to AF and the ICH was not related to trauma. Results From 2003–2015 a total of 1405 patients with AF and ICH were included, mean age of 79.4 years [Table]. 40% had suffered a “mild” index ICH, and approximately 25% had a “moderate” or a “severe” index event based on the SSS score. Hypertension (75%) and prior thromboembolic events (33%) were common comorbidities. In the year before the index ICH, 27% recieved antiplatelet therapy, 34% OAC, and 22% receiving both treatments.
