1. What is the New Australian CVD Risk Calculator?

The New Australian CVD Risk Calculator estimates 5-year cardiovascular disease risk for Australians using an adaptation of the NZ/Framingham risk equation. It incorporates age, lipid levels, blood pressure, and smoking status to provide personalized risk assessment.

2. How Does the Calculator Work?

The calculator uses the NZ/Framingham adaptation equation:

\[ Risk \% = NZ/Framingham \ adaptation: \ logistic \ on \ age, \ lipids, \ BP, \ etc. \]

Where:

\( Age \) — Age in years
\( Lipids \) — Lipid levels in mmol/L
\( BP \) — Blood pressure in mmHg (systolic and diastolic)
\( Smoking \) — Smoking status (yes/no)

Explanation: The equation uses logistic regression to estimate 5-year cardiovascular disease risk based on multiple risk factors, specifically adapted for the Australian population.

3. Importance of CVD Risk Assessment

Details: Accurate CVD risk assessment helps identify individuals who may benefit from preventive interventions, lifestyle modifications, and medical treatments to reduce cardiovascular event risk.

4. Using the Calculator

Tips: Enter age in years, lipid levels in mmol/L, blood pressure readings in mmHg, and smoking status. All values must be valid and within reasonable physiological ranges.

5. Frequently Asked Questions (FAQ)

Q1: What does the 5-year CVD risk percentage mean?
A: It represents the probability of experiencing a cardiovascular event (heart attack, stroke, etc.) within the next 5 years.

Q2: What is considered high risk?
A: Generally, risk ≥15% over 5 years is considered high and may warrant preventive treatment.

Q3: How often should CVD risk be assessed?
A: Every 2-5 years for adults over 45, or more frequently if risk factors change significantly.

Q4: Are there limitations to this calculator?
A: It may not accurately estimate risk for people with established CVD, diabetes, chronic kidney disease, or very high single risk factors.

Q5: Can lifestyle changes affect my risk?
A: Yes, quitting smoking, improving diet, increasing physical activity, and managing blood pressure can significantly reduce CVD risk.
