This calculator is intended as a tool to assess cardiovascular risk and engage patients in managing their risk factors. It uses 4 different risk engines depending on the patients medical history i.e. if he/she has diabetes, vascular disease, chronic kidney disease or none of those conditions. In the case where more than 1 risk engine could be used (e.g., patient has diabetes and vascular disease), the system will default to using the risk engine generating the highest risk.
