biostudies-literatureUnknown56(6)Drescher C<h4>Introduction</h4>Ischemic stroke incidence appears to have decreased during the last decades, but most studies focus on the first-ever events and epidemiological data on recurrent stroke are scarce. The aim of our study was to investigate trends in incidence, risk factors, and medication in patients with first-ever and recurrent ischemic stroke between 2010 and 2019 in Sweden.<h4>Methods</h4>We included patients (≥18 years old) with ischemic stroke registered in the hospital-based Swedish Stroke Register (Riksstroke) 2010-2019. The coverage of Riksstroke was consistently high (about 90%) during this period. Data were stratified by first-ever and recurrent ischemic stroke in three different time periods (2010-2012, 2013-2016, and 2017-2019) and shown as crude and age-specific incidence Neuroepidemiology433-442https://www.ebi.ac.uk/biostudies/studies/S-EPMC9945185biostudies-literatureEpidemiology of First and Recurrent Ischemic Stroke in Sweden 2010-2019: A Riksstroke Study.PMC9945185Pihlsgard MNorrving BPetersson JDrescher CUllberg TBuchwald FfalseEpidemiology of First and Recurrent Ischemic Stroke in Sweden 2010-2019: A Riksstroke Study.<h4>Introduction</h4>Ischemic stroke incidence appears to have decreased during the last decades, but most studies focus on the first-ever events and epidemiological data on recurrent stroke are scarce.
