The degree of international neuro-cardio pathway heterogeneity, specifically between the USA and the UK, has not been studied previously. Methods: We conducted a retrospective review of consecutive patients with cryptogenic, large-vessel disease (LVD) and small-vessel disease (SVD) ischaemic strokes at large, certified stroke centres in the USA and UK. Qualitative assessments included stroke aetiology determination and post-stroke cardiac monitoring frequency by methodology. Results: Between 2017 and 2020, we identified 881 stroke patients within the UK (189) and USA (692), respectively, with significant differences in aetiological classification for cryptogenic (50.8% vs. 33.1%, p &lt; 0.001) and LVD (16.9% vs. 37.0%, p &lt; 0.001), but not for SVD strokes (32.3% vs. 29.9%, p = 0.532). Insertable cardiac monitors were significantly less utilised for UK vs. US patients (5.9% vs. 10.6%, p = 0.049); however, external monitor utilisation (68.8% vs. 66.9%, p = 0.628) was similar. Correspondingly, AF was diagnosed significantly less in the UK (1.5% vs. 7.5%, p = 0.012). Conclusion: Among hospitalised ischaemic stroke patients at comprehensive stroke centres in the USA and UK, significant differences exist in aetiological classification, cardiac monitoring, and subsequent AF diagnosis. Larger Anglo-American studies may confirm this finding, identify disparities in care, and standardise neuro-cardio pathways internationally to improve outcomes.<\/jats:p>","DOI":"10.1159\/000548286","type":"journal-article","created":{"date-parts":[[2025,9,29]],"date-time":"2025-09-29T16:01:08Z","timestamp":1759161668000},"page":"564-570","source":"Crossref","is-referenced-by-count":0,"title":["Heterogeneity
