GARFIELD-AF Risk Calculator

Compare the effects of different anticoagulant treatment decisions in atrial fibrillation


The GARFIELD-AF risk calculator was designed to help clinicians assess the future risk of mortality, ischaemic stroke and major bleeding (including haemorrhagic stroke), as a guide to using anticoagulants in patients with a new diagnosis of atrial fibrillation (AF).

It simultaneously provides the risks for up to 24 months of:

  • Mortality
  • Ischaemic Stroke or Systemic Embolism
  • Major Bleeding Incl. Haemorrhagic Stroke

It allows clinicians to compare the effects of different anticoagulant treatment decisions – no oral anticoagulation (no OAC), vitamin K antagonist (VKA), non-vitamin K oral anticoagulant (NOAC) – based on the results from similar patients in the GARFIELD-AF Registry.

It uses routinely collected clinical data and includes a total of 16 questions.

It has been derived from the GARFIELD-AF population and externally validated.
