Among ischemic strokes, 25 % to 40 % are classified as cryptogenic, with patent foramen ovale (PFO) identified as a potential underlying cause. PFO is found in 25 % of the general population. Despite the significant occurrence of PFO-associated strokes, the associated costs remain largely unexplored.</div></div><div><h3>Aim</h3><div>This study aimed to evaluate the annual economic burden of PFO-associated stroke in the US.</div></div><div><h3>Methods</h3><div>A cost-of-illness study was performed, encompassing the direct and indirect costs of PFO-associated stroke on both society and the healthcare system. The model adopted a top-down approach and a one-year, US societal perspective. A payer perspective and bottom-up costing approach were included as scenario analyses. Data was obtained by a targeted literature review.</div></div><div><h3>Results</h3><div>The societal model, assuming 32.5 % cryptogenic strokes, incurs an annual cost of over $1.3 billion in the US, with over $1.0 billion coming from new strokes and over $300 million from recurrent strokes. The majority of the costs are indirect—50 % from productivity losses due to premature death and 27 % from other productivity losses. Direct costs constitute 23 % of the total. From the payer perspective, the annual costs for PFO-associated strokes in the US were estimated at $302 million, with hospitalization costs comprising 44 %, followed by prescriptions and outpatient care at 19 % and 16 %, respectively.</div></div><div><h3>Conclusion</h3><div>The economic burden of PFO-associated strokes in the US is substantial, exceeding $1.3 billion per year. Different types of medical management or surgical treatments for PFO-associated stroke could lead to gains in both costs and health outcomes.</div></div>","PeriodicalId":54368,"journal":{"name":"Journal of Stroke & Cerebrovascular Diseases","volume":"34 6","pages":"Article 108319"},"PeriodicalIF":2.0,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143863717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
