1. What is the Australian Absolute CV Risk Calculator?

The Australian Absolute CV Risk Calculator estimates 5-year cardiovascular disease risk using Australian charts or PREDICT equation. It considers multiple risk factors to provide a comprehensive assessment of cardiovascular health.

2. How Does the Calculator Work?

The calculator uses the Australian CV risk equation:

\[ Risk \% = f(age, sex, smoking, SBP, TC:HDL, diabetes) \]

Where:

\( age \) — Age in years
\( sex \) — Male or female
\( smoking \) — Smoking status (yes/no)
\( SBP \) — Systolic blood pressure (mmHg)
\( TC:HDL \) — Total cholesterol to HDL ratio
\( diabetes \) — Diabetes status (yes/no)

Explanation: The equation combines multiple cardiovascular risk factors using validated Australian risk prediction models to estimate 5-year absolute risk.

3. Importance of CV Risk Assessment

Details: Cardiovascular risk assessment helps identify individuals at high risk for heart attacks, strokes, and other cardiovascular events, enabling early intervention and preventive measures.

4. Using the Calculator

Tips: Enter age in years, select sex and smoking status, provide systolic blood pressure in mmHg, TC:HDL ratio, and diabetes status. All values must be valid for accurate risk estimation.

5. Frequently Asked Questions (FAQ)

Q1: What is considered high cardiovascular risk?
A: Generally, ≥15% 5-year risk is considered high, though thresholds may vary based on guidelines and individual circumstances.

Q2: How accurate is this calculator?
A: The calculator uses validated Australian risk prediction models, but individual results should be interpreted in clinical context with healthcare professional guidance.

Q3: What age range is appropriate for this calculator?
A: Typically used for adults aged 40-74 years, though some models may have different age ranges.

Q4: Can this calculator be used for people with existing heart disease?
A: No, this calculator is for primary prevention in people without established cardiovascular disease.

Q5: How often should cardiovascular risk be assessed?
A: Recommended every 2-5 years for adults without known CVD, or more frequently if risk factors change significantly.
