Abstract Aims Compliance with integrated care based on the Atrial fibrillation Better Care (ABC) pathway has been associated with improved clinical outcomes. The primary objective of this study was to compare clinical outcomes of AF patients according to the compliant status of each component of the ABC pathway in a hierarchical win ratio approach. Methods and results We studied AF patients in the COOL-AF registry. Each patient was followed every 6 months until 3 years. A win ratio analysis was performed, as not all clinical outcomes are equivalent. The hierarchical outcomes were (1) all-cause death, (2) intracranial haemorrhage (ICH), (3) ischaemic stroke/systemic embolism, (4) non-ICH major bleedings, and (5) acute myocardial infarction or heart failure. We also assessed win ratio and win proportion variance over the follow-up time, and the variations over time. A total of 3405 patients (mean age 67.8 ± 11.3; 41.8% female) were studied. Win ratio of ABC-compliant (all three components) vs. ABC-not-compliant was 1.57 (1.35–1.83), P < 0.001. When adding time in therapeutic range (TTR) data for compliant criteria for those who were on warfarin, the win ratio increased to 2.28 (1.89–2.75), P < 0.001. The A-compliant group (plus TTR data), B-compliant, and C-compliant had the win ratio of 1.81 (1.51–2.12), 1.82 (1.53–2.16), and 1.39 (1.18–1.62), all P < 0.001, compared to not compliant group. Conclusion Management of AF patients according to each component of the ABC pathway is associated with better clinical outcomes compared to those non-compliant to ABC pathway. This finding underscores the importance of a holistic management approach strategy for AF patients. Graphical Abstract Graphical Abstract
