1. What is the Absolute CV Risk Calculator Australia?

The Absolute CV Risk Calculator Australia uses the New Zealand/Australia cardiovascular disease risk equation to estimate the 5-year absolute risk of a cardiovascular event. This calculator is specifically validated for the Australian population.

2. How Does the Calculator Work?

The calculator uses the NZ/AUS CVD risk equation:

\[ Risk \% = f(Age, Sex, SBP, Cholesterol, Smoking, Diabetes) \]

Where:

\( Age \) — Age in years (20-79)
\( Sex \) — Male or Female
\( SBP \) — Systolic Blood Pressure (mmHg)
\( Cholesterol \) — Total and HDL cholesterol (mmol/L)
\( Smoking \) — Current smoking status
\( Diabetes \) — Diabetes mellitus diagnosis

Explanation: The equation calculates the probability of experiencing a cardiovascular event (heart attack, stroke) within the next 5 years based on multiple risk factors.

3. Importance of CVD Risk Assessment

Details: Cardiovascular risk assessment helps identify individuals who may benefit from preventive interventions, lifestyle modifications, and medical treatments to reduce their risk of heart disease and stroke.

4. Using the Calculator

Tips: Enter accurate values for all parameters. Use fasting lipid profiles for cholesterol measurements. Blood pressure should be measured in a clinical setting. Age range is typically 20-79 years for this calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is considered high cardiovascular risk?
A: Generally, ≥15% 5-year risk is considered high, 10-15% moderate, and <10% low risk according to Australian guidelines.

Q2: How often should CVD risk be assessed?
A: Every 2 years for people aged 45-74 years, or from age 35 for Aboriginal and Torres Strait Islander peoples.

Q3: Does this calculator apply to all ethnic groups?
A: The equation is specifically validated for Australian and New Zealand populations. Different equations may be needed for other ethnic groups.

Q4: What if I'm on blood pressure or cholesterol medication?
A: Use current values while on treatment. The calculator assesses current risk status regardless of medication use.

Q5: Can this calculator be used for people with existing heart disease?
A: No, this calculator is for primary prevention in people without known cardiovascular disease.
