Summary
Many studies suggest a higher incidence of thromboembolic syndromes such as stroke,
peripheral arterial thrombosis and pulmonary embolism in patients with heart failure
(HF), particularly those with left ventricular systolic dysfunction. As a result,
some clinicians have chosen to treat patients with HF with anticoagulants as primary
prevention against thromboembolic events. However, this practice is not well-supported
by scientific data. Retrospective analyses of large HF trials have yielded contradictory
results and randomised trials designed to specifically address this question have
been under-populated and under-powered. As a result, there is no general consensus
among professional societies in either recommending or advising against anticoagulants
in HF. We hope that ongoing clinical trials, WARCEF in particular, will yield results
that will guide clinicians in deciding for or against routine use of anticoagulants
in HF.
