Cardiovascular Disease Risk Checker | WHO Risk Score 2026
Cardiovascular disease (CVD) is the leading cause of death globally, but many cases are preventable through early detection and lifestyle modifications. The WHO has developed validated risk prediction algorithms to estimate the 10-year risk of developing CVD based on key risk factors.
This calculator assesses your 10-year CVD risk by evaluating your age, gender, blood pressure, cholesterol levels, diabetes status, and smoking history. Understanding your risk can help you make informed decisions about your health.

Assessment Examples
Example 1 �?High Risk Male
Age = 60, Male, BP = 150/95, Cholesterol = 240 mg/dL
Smoker = Yes, Diabetes = Yes, BMI = 32
10-Year CVD Risk = 25-30%
Classification = High Risk
Recommendation = Immediate medical consultation
Smoker = Yes, Diabetes = Yes, BMI = 32
10-Year CVD Risk = 25-30%
Classification = High Risk
Recommendation = Immediate medical consultation
Example 2 �?Low Risk Female
Age = 45, Female, BP = 118/76, Cholesterol = 180 mg/dL
Smoker = No, Diabetes = No, BMI = 24
10-Year CVD Risk = <5%
Classification = Low Risk
Recommendation = Continue healthy lifestyle
Smoker = No, Diabetes = No, BMI = 24
10-Year CVD Risk = <5%
Classification = Low Risk
Recommendation = Continue healthy lifestyle

WHO Cardiovascular Disease Risk Categories
The WHO classifies 10-year CVD risk into four categories based on the probability of developing a cardiovascular event:
| Risk Category | 10-Year Risk | Intervention Level | Color Code |
|---|---|---|---|
| Low Risk | < 5% | Primary prevention only | Green |
| Low-Moderate | 5 - 10% | Lifestyle intervention | Yellow |
| Moderate-High | 10 - 20% | Lifestyle + medication consideration | Orange |
| High Risk | > 20% | Intensive intervention | Red |
Key Risk Factors and Their Impact
| Risk Factor | Increase in CVD Risk | Evidence Level |
|---|---|---|
| High Blood Pressure | 2-4x higher risk | Strong |
| High LDL Cholesterol | 1.5-2x higher risk per 30 mg/dL increase | Strong |
| Diabetes | 2-4x higher risk | Strong |
| Current Smoking | 2-4x higher risk | Strong |
| Obesity (BMI > 30) | 1.5-2x higher risk | Moderate |
| Physical Inactivity | 1.5x higher risk | Moderate |
| Age > 55 (men) / > 65 (women) | Increased risk with age | Strong |
Primary Prevention Strategies
For individuals at risk, the following strategies are recommended by WHO and AHA:
- Blood Pressure Control: Target < 130/80 mmHg
- Cholesterol Management: LDL < 70 mg/dL for high-risk individuals
- Smoking Cessation: Complete cessation reduces risk by 50% within 1 year
- Diabetes Control: HbA1c < 7%
- Physical Activity: 150 minutes/week moderate exercise
- Healthy Diet: Mediterranean or DASH diet pattern
- Weight Management: Maintain BMI 18.5-24.9

Frequently Asked Questions
-
Cardiovascular disease refers to a group of disorders of the heart and blood vessels, including coronary artery disease (heart attacks), cerebrovascular disease (strokes), peripheral artery disease, and heart failure. CVD is the leading cause of death globally, accounting for approximately 17.9 million deaths each year.
-
Major risk factors include: age (increasing risk with age), gender (men at higher risk until menopause), high blood pressure, high cholesterol (especially LDL), diabetes, smoking, obesity, physical inactivity, unhealthy diet, and family history of CVD.
-
This calculator uses WHO risk prediction algorithms validated in multiple populations. However, it provides only an estimate. Individual risk may vary based on unmeasured factors. Always consult with a healthcare provider for personalized risk assessment.
-
If your risk is high, consult a healthcare provider promptly. They may recommend: lifestyle modifications (diet, exercise, smoking cessation), medication for blood pressure or cholesterol, regular monitoring, and screening for other risk factors like diabetes.
