1. What is the SCORE Risk Equation?

The SCORE (Systematic COronary Risk Evaluation) system estimates 10-year risk of fatal cardiovascular disease in apparently healthy individuals. It's based on data from European cohort studies.

2. How Does the Calculator Work?

The calculator uses the SCORE equation:

\[ Risk (\%) = 1 - S0(age)^{exp(LPI)} \] \[ LPI = \beta_{chol} \times cholesterol + \beta_{smoke} \times smoke + \beta_{sbp} \times (SBP - 120) \]

Where:

\( S0 \) — Baseline survival function
\( age \) — Age in years (40-65)
\( \beta_{chol} \) — Cholesterol coefficient
\( cholesterol \) — Total cholesterol (mmol/L)
\( \beta_{smoke} \) — Smoking coefficient
\( smoke \) — Current smoker (0=no, 1=yes)
\( \beta_{sbp} \) — Systolic BP coefficient
\( SBP \) — Systolic blood pressure (mmHg)

Explanation: The equation calculates risk based on individual risk factors compared to a baseline population.

3. Importance of CVD Risk Calculation

Details: The SCORE risk assessment helps identify high-risk individuals who may benefit from preventive interventions like lifestyle changes or medication.

4. Using the Calculator

Tips: Enter accurate values for all parameters. Age range is 40-65 years. Use fasting cholesterol values when possible.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between low and high risk regions?
A: Low risk regions have lower baseline CVD mortality (e.g., Belgium, France). High risk regions have higher baseline mortality (e.g., Eastern Europe).

Q2: Why is age limited to 40-65?
A: The SCORE system was validated for this age range. For younger individuals, lifetime risk may be more relevant.

Q3: What risk level requires intervention?
A: Generally ≥5% 10-year risk is considered high and may warrant intervention, but thresholds vary by country.

Q4: Does SCORE account for family history?
A: No, family history is not in the basic SCORE model but should be considered in clinical decision making.

Q5: Can SCORE be used for diabetics?
A: Diabetics are automatically considered high risk regardless of SCORE result, as diabetes is a CVD risk equivalent.
