PREVENTTM Online Calculator

Welcome to the American Heart Association Predicting Risk of cardiovascular disease EVENTs (PREVENTTM). This app should be used for primary prevention patients (those without atherosclerotic cardiovascular disease or heart failure) only.

Intended Use of PREVENT:
This calculator is intended for primary prevention patients (those without coronary heart disease, stroke, or heart failure) who are between the ages of 30-79 years. Estimating absolute risk may assist and guide clinicians and patients in shared decision-making for interventions targeting lifestyle behaviors and consideration of pharmacotherapies.

Description of the PREVENT models:

The calculator provides 10-year risk estimates for individuals 30-79 years of age and provides 30-year risk estimates for individuals 30-59 years of age. The PREVENTTM equations were developed by the American Heart Association Cardiovascular-Kidney-Metabolic Scientific Advisory Group. The risk equations were derived and validated in a large, diverse sample of over 6 million individuals.1,2 The current version of this online calculator estimates risk using the base model. Add-on models that incorporate Hemoglobin A1c, urine albumin-to-creatinine ratio, and social deprivation index) are currently under development. Of note, the risk for each outcome (CVD, ASCVD, HF) is calculated by separate models. Individuals may develop both ASCVD and HF. Therefore, the predicted risk of the components (ASCVD, HF) may be greater than the predicted risk of the composite outcome (CVD).

Interpretation of Risk Estimates:

10-year risk for CVD is categorized as:

  • Low risk (<5%)
  • Borderline risk (5% to 7.4%)
  • Intermediate risk (7.5% to 19.9%)
  • High risk (≥20%)

*Patients with risk factor values outside the validated ranges of this tool require individualized assessment and management
