Abstract: Patients at High Bleeding Risk (HBR) are a sizable part of the population undergoing
Percutaneous Coronary Intervention (PCI) and stent implantation. This population historically
lacks standardized definition, thus limiting trial design, data generalizability, and clinical decision--
making. To overcome this limitation, the Academic Research Consortium (ARC) has recently released
comprehensive guidelines defining HBR criteria for study design purposes and daily clinical
practices. Furthermore, several risk scores have been developed aiming to discriminate against
HBR patients and support physicians for clinical decision-making when faced with this complex
subset of patients. Accordingly, the first part of this review article will explore guideline-recommended
risk scoring as well as ARC-HBR criteria and their relative application for daily clinical
practice. The second part of this review article will explore the complex interplay between the risk
of bleeding and coronary thrombotic events in patients deemed at HBR. Indeed, several features
that identify these patients are also independent predictors of recurrent ischemic events, thus challenging
revascularization strategies and optimal antithrombotic therapy. Accordingly, several clinical
trials have been conducted to evaluate the safety and efficacy of the new generation of coronary
platforms and different antithrombotic strategies for HBR patients to minimize both ischemic and
bleeding events. Accordingly, in this part, we discuss current guidelines, trials, and observational
data evaluating antithrombotic strategies and stent technologies for patients at HBR.
