Everlab’s Cardiac Risk Calculator
Most people don’t think about cardiovascular health until chest pain forces them to. By then, plaque may have been building in the arteries for some time.
Heart disease often develops quietly, frequently with no symptoms until a significant event occurs. That is why we created the Everlab cardiac risk calculator: to give you a clearer picture of your heart health before problems develop.
The earlier you know, the more time you have to change the trajectory.
The best part? It takes two minutes, uses information you already know, and costs nothing.
Why Your Risk Score Matters
- Heart disease remains the leading cause of death globally.
- 1 in 5 adults aged 45 to 75 has a moderate to high cardiovascular disease risk.
- 80% of cardiovascular disease is preventable with early intervention.
- By age 50, many individuals already have atherosclerotic cardiovascular disease (plaque buildup).
Early detection gives you time. Time to make lifestyle changes, start treatment when needed, and focus on prevention rather than recovery.
What is a Cardiac Risk Calculator?
A cardiac risk calculator is a screening tool that estimates your probability of having a heart attack, stroke, or other cardiovascular event in the next 5 years.
It uses personal health information, such as age, blood pressure, smoking status, and body mass index, to assess your future risk of cardiovascular disease.
It is not a diagnosis and not a guarantee. It is a probability based on how these factors combine in people similar to you.
What Everlab’s Cardiac Risk Calculator Measures
Who Should Use This Calculator?
Everlab’s cardiac risk calculator is designed for individuals who have not yet developed cardiovascular disease but want to understand their future risk.
You should use this calculator if you are:
- Aged 18 to 79 with no history of heart disease.
- Aboriginal or Torres Strait Islander aged 18 to 79 (these populations may develop atherosclerotic cardiovascular disease earlier, and early screening catches problems when intervention has a significant impact).
- Living with diabetes (diabetes can accelerate cardiovascular risk).
- Anyone curious about their heart health who wants a quick, evidence-based estimate.
Do NOT use this calculator if you have:
- Known CVD: If you have had a heart attack, stroke, or been diagnosed with atherosclerotic cardiovascular disease, you are already at high risk and require clinical management rather than screening.
- Familial hypercholesterolaemia: This genetic condition, causing extremely high cholesterol, requires a specialised assessment.
- Chronic kidney disease: These conditions change your cardiovascular risk in ways this general calculator cannot capture.
If any of these apply to you, skip the calculator and consult with a doctor for specialised testing.
How Your Cardiac Risk is Calculated
The calculator asks for basic information you either know or can estimate. Each factor influences cardiovascular disease risk in measurable ways.
- Your age: Risk increases naturally as you get older because arteries change and plaque can accumulate.
- Sex assigned at birth: Men tend to develop heart disease earlier. Women’s risk increases significantly after menopause as protective hormone levels drop.
- Smoking status: Smoking damages blood vessels and accelerates plaque formation. Even being a current smoker makes a significant difference in predicting risk. There is no safe level of smoking.
- Blood pressure range: Both systolic and diastolic blood pressure directly affect risk. High blood pressure often damages arteries without any noticeable symptoms.
- Body mass index (BMI): Calculated from height and weight. A higher BMI generally correlates with increased risk, though it does not tell the complete story of your body composition.
Understanding Your Results
After you complete the calculation, you get a score out of 10 and a category based on Australian clinical guidelines.

What Your Results Will Show
You will receive your score via email.
The results will show your risk score, risk level, BMI, risk explanation and personalized insights.
The personalized insights explain which factors are affecting your score.
For instance:
- Healthy blood pressure: The tool will confirm if this major risk factor is working in your favour or against.
- Elevated BMI: The calculator may show how reaching a healthy BMI range (18.5 to 24.9) could reduce your score.
- Smoking: The calculator flags this as a high-impact modifiable factor. For example, quitting smoking often provides a larger reduction in risk than any other single change.
Understanding Your Trajectory
The calculator shows you a potential path based on your current health data.
- Low Risk: Near-term risk looks low. Focus on maintenance and recheck in 1 to 2 years.
- Intermediate/Moderate Risk: Small changes to blood pressure, weight, or smoking status can often move you down to the low-risk category.
- High Risk: This suggests a need for a clinical consultation. Both lifestyle changes and medications are often discussed at this stage.
What the Calculator Cannot Tell You
This screening tool has important limitations:
- It does not measure actual disease: A risk score is an estimate. It does not show if you currently have plaque, heart valve problems, early heart damage, or any other actual medical conditions.
- It does not include all risk factors: It does not ask about other risk factors like cholesterol numbers (LDL/HDL), family history, or advanced markers like Apolipoprotein B.
This is why the calculator is a starting point. It identifies who should pursue a more comprehensive assessment.
Why is Comprehensive Testing Important?
In our experience testing over 1,000 Australians, we found that many biomarkers can fall outside the optimal range even when a person feels fine.
A comprehensive cardiovascular assessment goes beyond the calculator to include:
- Detailed lipid panels (ApoB, Lp(a), and triglycerides).
- Fasting glucose and HbA1c for diabetes screening.
- Kidney function and body composition analysis.
- Imaging, such as coronary artery calcium scoring, where appropriate.
How to Improve Your Heart Disease Risk Score
Because your score reflects your current status, changing the inputs can change your trajectory.
- Physical activity: Aim for 150 minutes of moderate activity weekly to strengthen the heart and improve blood pressure.
- Weight management: Even a 5 to 10% weight loss can improve multiple risk factors.
- Smoking cessation: Benefits are almost immediate. Within one year of quitting, the risk of coronary heart disease drops significantly.
- Dietary improvements: Favour whole foods, vegetables, and healthy fats.
When to Recheck Your Cardiac Risk
Your risk changes as you age or as your habits shift.
- Low Risk: Recheck every 1 to 2 years.
- Intermediate Risk: Recheck every 6 to 12 months to track lifestyle changes.
- High Risk: Monitor every 3 to 6 months in consultation with a doctor.
Bottom Line
Everlab’s risk calculator tells you where you stand today. Your choices help determine where you will be in five years. This information is the first step toward understanding your specific situation.
Frequently Asked Questions
1. What if I don’t know my blood pressure?
You can estimate using the ranges provided. For more accurate results, joining the Everlab program will make sure you get your real blood pressure measured as part of the larger bloods panel.
2. My score is low. Am I safe forever?
Low 5-year risk does not mean zero lifetime risk. Heart disease prevention is a lifelong effort. Use a low-risk result as motivation to maintain your healthy habits.
3. Can I improve my score quickly?
Yes. Your score reflects your current status. Lifestyle changes like quitting smoking can lower risk factors within weeks, while blood pressure and cholesterol changes usually take 1 to 6 months to stabilise.
