1. What is the Cardiovascular Risk Score?

The Cardiovascular Risk Score estimates the probability of developing cardiovascular disease within a specific time period (usually 10 years) based on individual risk factors. It helps identify high-risk individuals who may benefit from preventive interventions.

2. How Does the Calculator Work?

The calculator uses the risk equation:

\[ \text{Risk (\%)} = 1 - S0(\text{age})^{\exp(\text{LPI})}; \quad \text{LPI} = \sum (\beta_i \times x_i) \]

Where:

\( S0 \) — Baseline survival function at given age
\( \text{LPI} \) — Linear predictor index (sum of coefficients × variables)
\( \beta_i \) — Coefficients for each risk factor
\( x_i \) — Risk factor values (age, cholesterol, etc.)

Explanation: The equation combines multiple risk factors with different weights to estimate individual risk.

3. Importance of Risk Calculation

Details: Accurate risk assessment helps guide preventive strategies, lifestyle modifications, and potential pharmacological interventions to reduce cardiovascular events.

4. Using the Calculator

Tips: Enter accurate values for all risk factors. Use fasting lipid values when possible. Blood pressure should be an average of multiple measurements.

5. Frequently Asked Questions (FAQ)

Q1: What risk factors are included?
A: Typically includes age, sex, smoking status, blood pressure, and cholesterol levels. Some models include diabetes and other factors.

Q2: What is considered high risk?
A: Generally ≥7.5% 10-year risk is considered elevated, though thresholds vary by guidelines.

Q3: How often should risk be assessed?
A: Every 4-6 years in adults 40-75 years without known CVD, or more frequently if risk factors change.

Q4: Are there population limitations?
A: Risk equations are population-specific. This calculator uses European coefficients - adjust for other populations.

Q5: Can risk be reduced?
A: Yes, through lifestyle changes (diet, exercise, smoking cessation) and medications (statins, antihypertensives) when appropriate.
