Abstract: BACKGROUND: The Japanese version of the high bleeding risk (J-HBR) criteria was proposed to identify Japanese patients at HBR after percutaneous coronary intervention. However, the diagnostic ability of the J-HBR in patients with lower extremity peripheral arterial disease (LEAD) remains unclear. METHODS AND RESULTS: This multicenter registry included 818 LEAD patients undergoing endovascular treatment (EVT). Based on J-HBR major (1 point) and minor (0.5 points) criteria, patients were grouped into LEAD with (≥2.0 points) and without (1.0-1.5 points) additional J-HBR. LEAD itself is a major criterion. The primary endpoint was major bleeding events and major adverse cardiovascular and limb events (MACLE), a composite of cardiovascular death, myocardial infarction, ischemic stroke, acute limb ischemia, and major amputation. Of the 818 patients in the study, 683 (83.5%) had LEAD with additional J-HBR. During the median follow-up period of 729 days, the risk of major bleeding events did not differ significantly between the 2 groups, although the risk of MACLE was higher in the LEAD with than without additional J-HBR group (12.4% vs. 5.9%; P=0.03). The probability of major bleeding and MACLE increased progressively with an increase in the number of J-HBR major and minor criteria. CONCLUSIONS: Among patients with LEAD undergoing EVT, the J-HBR criteria successfully stratified ischemic and bleeding risks. This risk-predicting model may be useful in patients with LEAD.
