Antithrombotic therapy and body mass: an expert position paper of the ESC Working Group on Thrombosis

Abstract
The success of trials that have shown net clinical benefits of antithrombotic drugs as well as the increasing prevalence of cardiovascular diseases in an ageing population have led to more widespread use of antiplatelet and anticoagulant drugs. At the same time, extremely low and high body weight (BW) are becoming more common due to a higher prevalence of frailty, associated with greater life expectancy, and the global epidemic of obesity, ‘globesity’, respectively.1–3 These extreme BWs may affect cardiovascular risk as well as the pharmacokinetics of antithrombotic drugs, some of which have relatively narrow therapeutic windows.
