CVD Risk Calculator (SCORE2 & ASCVD Estimator)
Estimate 10-year risk of cardiovascular disease (CVD) based on age, cholesterol, smoking, and blood pressure. Dual-mode calculator for high and low risk regions.
About
Cardiovascular disease (CVD) remains the leading cause of mortality globally. Early detection and risk stratification are paramount for prevention. This CVD Risk Calculator is a screening tool inspired by algorithms like SCORE2 (Europe) and ASCVD (USA). It estimates the 10-year probability of a fatal or non-fatal cardiovascular event (such as stroke or myocardial infarction).
This tool is distinct because it adjusts for regional risk baselines—users can toggle between 'Low Risk' regions (e.g., France, Spain) and 'High Risk' regions (e.g., Eastern Europe). The results are presented not just as a number, but as an actionable zone (Low, Moderate, High, Very High) with corresponding lifestyle recommendations tailored to the specific risk factors input by the user.
Formulas
Risk estimation is based on a multivariate regression model considering:
- Age & Gender: Risk doubles roughly every decade.
- Systolic BP: Each 20mmHg increase doubles CV mortality risk.
- Cholesterol: Non-HDL cholesterol is the primary lipid driver in this model.
- Smoking: Multiplies risk by a factor of 1.5x to 2.5x.
The simplified logic for this estimator uses weighted coefficients:
Reference Data
| Risk Category | 10-Year Risk Score | Clinical Recommendation |
|---|---|---|
| Low Risk | < 2.5% | Maintain healthy lifestyle. Re-assess in 5 years. |
| Moderate Risk | 2.5% to 7.5% | Dietary changes, increase physical activity, consider lipid management. |
| High Risk | 7.5% to 15% | Intensive lifestyle intervention, BP control, likely statin therapy. |
| Very High Risk | > 15% | Immediate medical intervention, strict target controls for LDL-C and BP. |
