We hypothesise a transient drug-related prothrombotic state with paradoxical embolisation via an atrial septal defect which was later found on bubble echocardiogram. We highlight a rare but important cause of stroke in younger patients which is relevant given the increasing use of AAS misuse among casual fitness enthusiasts. We explore the various possible mechanisms by which AAS use can increase ischaemic stroke risk in such patients.<\/jats:p>","DOI":"10.1136\/bcr-2020-234241","type":"journal-article","created":{"date-parts":[[2021,2,4]],"date-time":"2021-02-04T16:05:20Z","timestamp":1612454720000},"page":"e234241","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Anabolic steroid use and ischaemic stroke in a young fitness enthusiast"],"prefix":"10.1136","volume":"14","author":[{"given":"James","family":"Choulerton","sequence":"first","affiliation":[{"name":"Stroke Unit, Royal United Hospital Bath NHS Trust, Bath, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nishan","family":"Guha","sequence":"additional","affiliation":[{"name":"Clinical Biochemistry, John Radcliffe Hospital, Oxford, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rebecca","family":"Squires","sequence":"additional","affiliation":[{"name":"Stroke Unit, Royal United Hospital Bath NHS Trust, Bath, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,2,4]]},"reference":[{"key":"2025082709090864000_14.2.e234241.1","doi-asserted-by":"publisher","DOI":"10.1210\/er.2013-1058"},{"key":"2025082709090864000_14.2.e234241.2","unstructured":"World Anti Doping Agency .
