Clinical Outcomes Based on High Bleeding Risk in Patients With Lower Extremity Peripheral Artery Disease Who Have Undergone Endovascular Therapy.

Endovascular therapies (EVTs) for symptomatic lower extremity peripheral artery disease (PAD) are efficient and minimally invasive. However, patients with PAD tend to have high bleeding risk (HBR), and there are limited data regarding the HBR for patients with PAD after EVT. Post EVT, most of the patients with PAD were classified as having HBR using the Academic Research Consortium for HBR (ARC-HBR) criteria and the rate of bleeding events as well as mortality and ischemic events within 2 years increased as the ARC-HBR score increased in this retrospective study of 732 participants. HBR patients with PAD can be at high risk of not only bleeding events but also mortality and ischemic events in the mid-term. The ARC-HBR criteria and its associated scores can successfully stratify HBR patients and assess the bleeding risk in patients with PAD who underwent EVT.
