1. What is the Cardiac Health Risk Calculator?

The Cardiac Health Risk Calculator estimates 10-year cardiovascular disease (CVD) risk using the Framingham/AusCVDRisk equation. It assesses the probability of developing heart disease, stroke, or other cardiovascular events based on key risk factors.

2. How Does the Calculator Work?

The calculator uses the Framingham risk equation:

\[ Risk \% = logistic(Age, Sex, Chol, SBP, Smoking, Diabetes) \]

Where:

\( Age \) — Age in years
\( Sex \) — Male or Female
\( Chol \) — Total cholesterol (mg/dL)
\( SBP \) — Systolic blood pressure (mmHg)
\( Smoking \) — Smoking status (Yes/No)
\( Diabetes \) — Diabetes status (Yes/No)

Explanation: The logistic function combines these risk factors to estimate the 10-year probability of cardiovascular events.

3. Importance of CVD Risk Assessment

Details: Early identification of cardiovascular risk helps in implementing preventive measures, lifestyle modifications, and appropriate medical interventions to reduce the likelihood of heart attacks, strokes, and other cardiovascular events.

4. Using the Calculator

Tips: Enter age in years, select sex, provide cholesterol in mg/dL, systolic blood pressure in mmHg, and indicate smoking and diabetes status. All values must be valid for accurate risk assessment.

5. Frequently Asked Questions (FAQ)

Q1: What is considered a high CVD risk?
A: Generally, risk ≥20% is considered high, 10-19% intermediate, and <10% low risk for 10-year cardiovascular events.

Q2: How accurate is this risk assessment?
A: The Framingham risk score is well-validated but provides population-level estimates. Individual risk may vary based on additional factors.

Q3: Can this calculator be used for all age groups?
A: It's typically validated for adults aged 30-74 years. Results outside this range should be interpreted with caution.

Q4: What other factors affect CVD risk?
A: Family history, physical activity, diet, stress levels, and other medical conditions can also influence cardiovascular risk.

Q5: How often should CVD risk be assessed?
A: Every 4-6 years for adults with low risk, more frequently for those with risk factors or previous assessments showing elevated risk.
