ARC-HBR高出血リスク基準
用途適応: before/at PCI when choosing stent strategy and DAPT duration.
層別Binary HBR definition (~≥4% 1-year BARC 3/5 or ≥1% ICH). More criteria → higher risk.
限界非適応: to withhold indicated PCI for ACS. · 落とし穴: scoring both major and minor CKD/anemia bands for the same pati… · Pair with ischemic risk (e.g. PRECISE-DAPT context).

計算方法と公式
HBR if ≥1 major OR ≥2 minor consensus criteria (Urban 2019 table).
Check mutually exclusive CKD/Hb/bleed/stroke pairs carefully so major and minor are not double-counted inappropriately.

結果の判読と層別
Binary HBR definition (~≥4% 1-year BARC 3/5 or ≥1% ICH). More criteria → higher risk.
