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). It helps identify individuals who may benefit from preventive interventions.

2. How Does the Calculator Work?

The calculator uses the risk equation:

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

Where:

\( S0(age) \) — Baseline survival function at given age
\( LPI \) — Linear predictor index
\( beta_i \) — Coefficient for each risk factor
\( x_i \) — Individual risk factors (age, gender, smoking status, etc.)

Explanation: The equation combines multiple risk factors using specific coefficients to estimate absolute risk.

3. Importance of Risk Assessment

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

4. Using the Calculator

Tips: Enter all required information accurately. The calculator requires age, gender, smoking status, cholesterol values, and blood pressure. All values must be valid.

5. Frequently Asked Questions (FAQ)

Q1: What risk thresholds are clinically significant?
A: Generally, <5% is low risk, 5-10% intermediate, and >10% high risk, though thresholds may vary by guideline.

Q2: How often should risk be reassessed?
A: Every 4-6 years in adults, or more frequently if risk factors change substantially.

Q3: What are the main limitations of risk scores?
A: They estimate population-level risk and may not capture individual variations or all risk factors.

Q4: Should this be used for everyone?
A: Most validated for ages 40-79 without existing CVD. Use clinical judgment for others.

Q5: How can I reduce my cardiovascular risk?
A: Lifestyle changes (diet, exercise, smoking cessation) and, when appropriate, medications like statins or antihypertensives.
