This tool helps clinicians show patients estimates of the benefits and harms for them of taking aspirin. The tool informs and helps them decide on taking aspirin, as it is a decision only they can make.

It takes into account whether they are on medications and/or have any other health conditions that can influence bleeding and CVD events. It is based on a New Zealand cohort of 245,028 patients. The data may not be relevant to patients in countries outside New Zealand.

The calculator is NOT suitable for the following patients 
  • aged less than 30 years
  • aged 75 years or more
  • with established CVD
  • with heart failure
  • with atrial fibrillation
  • with familial hypercholesterolaemia
  • with chronic kidney disease (eGFR <30)
  • with diabetes with overt nephropathy OR diabetes with other renal disease (eGFR <45)
  • with an intracerebral bleed
  • who are currently receiving aspirin, other antiplatelet medication, or anticoagulant medication
