🆕 Revolutionary Risk Assessment
PREVENT replaces the Pooled Cohort Equations with contemporary data from more than 6.6 million participants across derivation and validation data sets, providing more accurate risk prediction for modern populations.
Use the official PREVENT calculator
This page explains PREVENT. Use the official American Heart Association calculator below to obtain a patient risk estimate from the validated equations.
Before interpreting a result
Use the calculator for primary prevention within its validated population. Enter the required clinical measurements, select the intended outcome and time horizon, and follow current guideline recommendations for interpretation.
The published equations are sex-specific and race-free. UACR, HbA1c and social deprivation index are optional additional predictors. A risk estimate supports a clinical discussion; it does not determine treatment by itself.
✨ PREVENT Advantages Over Legacy Equations
🕐 Contemporary Data
Developed and externally validated using multiple contemporary US data sets
🌍 Diverse Populations
3.28 million participants in derivation and 3.33 million in external validation
🏠 Social Determinants
Optional social deprivation index can add context to the clinical predictors
🫘 Kidney Function
Includes eGFR as independent predictor, enhancing accuracy in CKD patients
📊 PREVENT vs Pooled Cohort Equations Comparison
| Feature | PREVENT | Pooled Cohort Equations |
|---|---|---|
| Data Source | 25 derivation and 21 validation data sets | 4 historical cohorts (1987-2002) |
| Sample Size | 6.61 million across derivation and validation | 24,626 participants |
| Social Factors | Optional social deprivation index | Not included |
| Kidney Function | eGFR included as predictor | Not included |
| Modern Therapy | Reflects contemporary treatment patterns | Pre-statin era data |
| Validation | Validated in multiple external cohorts | Overestimated risk in some populations |
| Age Range | 30-79 years | 40-79 years |
🎯 Clinical Implementation
✅ When to Use PREVENT
- Stage 1 HTN treatment decisions
- Shared decision-making discussions
- Preventive therapy prioritization
- Patient risk communication
⚠️ Limitations
- Age restricted to 30-79 years
- Not validated in all ethnic groups
- Social Deprivation Index availability varies
- May not reflect local population characteristics
