ABSTRACT

BACKGROUND: The Japanese high-bleeding-risk criteria (Japanese-HBR), modified criteria of the Academic Research Consortium (ARC) HBR, has been recently proposed. We aimed to investigate the prevalence of the ARC-HBR and the Japanese-HBR, and to assess their prognostic significance in patients with acute myocardial infarction (AMI).

METHODS AND RESULTS: We applied the ARC-HBR and the Japanese-HBR criteria to the OACIS prospective multicenter acute myocardial infarction registry (12,093 patients, 66 ± 12 years, 9,096 males). The primary endpoint was fatal bleeding (BARC-5). Median follow-up duration was 4.84 [inter-quartile range 1.35, 5.01] years. Prevalence of the ARC-HBR was 43.8%, while that of the Japanese-HBR was 61.8%. Cumulative incidence of fatal bleeding was higher in the ARC-HBR group than in the no ARC-HBR group at 1 year (1.3 vs. 0.6%) and at 5 years (2.0 vs. 0.7%). The Kaplan-Meier curves stratified by the Japanese-HBR criteria more prominently diverged (1.3 vs. 0.2% at 1 year; and 1.9 vs. 0.3% at 5 years). The Japanese-HBR criteria showed superior discriminative performance over the ARC-HBR criteria (C-statistics: 0.677 vs. 0.598, P < 0.001).

CONCLUSIONS: In the real-world Japanese AMI registry, nearly half of the patients fulfilled the criteria of ARC-HBR, and two-thirds met the Japanese-HBR. Our findings support the validity of both ARC- and Japanese-HBR criteria in AMI patients but encourage the future application of the Japanese-HBR criteria to the Japanese AMI cohort.
