ReviewOral anticoagulation challenges and therapeutic dilemmas in the very elderly: to treat and how to treat octogenarians and nonagenarians?
The proportion of very elderly patients, namely octogenarians and nonagenarians, is expected to rise substantially over the next decades. This population is more prone to age‑dependent diseases associated with higher thromboembolic and bleeding risks. The very elderly are under‑represented in oral anticoagulation (OAC) clinical trials. ⋯ When prescribing OAC in this population, an individualized, yet holistic, approach accounting for comorbidities, comedications, altered physiological function, pharmacovigilance, frailty, compliance, and risk of falls is useful. However, given the limited randomized‑level evidence on OAC treatment in the very elderly, there are still pending questions. This review will discuss recent evidence, important practical aspects, and future directions for anticoagulation treatment in atrial fibrillation, venous thromboembolism, and peripheral artery disease in octogenarians and nonagenarians.
