1. What is CVD Risk Calculation?

Cardiovascular disease (CVD) risk calculation estimates the probability of developing heart disease or stroke over a specific period. This calculator uses validated models like QRISK3 to provide accurate risk assessment based on multiple clinical factors.

2. How Does the Calculator Work?

The calculator uses the CVD risk equation:

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

Where:

\( Age \) — Age in years
\( Sex \) — Male or Female
\( SBP \) — Systolic blood pressure (mmHg)
\( Cholesterol \) — Total cholesterol level (mmol/L)
\( Smoking \) — Current smoking status
\( Diabetes \) — Diabetes diagnosis status

Explanation: The equation combines multiple risk factors using weighted coefficients from large population studies to estimate 10-year cardiovascular risk.

3. Importance of CVD Risk Assessment

Details: Accurate CVD risk assessment helps identify individuals who may benefit from preventive interventions like statin therapy, blood pressure management, and lifestyle modifications to reduce future cardiovascular events.

4. Using the Calculator

Tips: Enter accurate clinical values including age, sex, systolic blood pressure, cholesterol level, smoking status, and diabetes status. Use fasting cholesterol values when possible for most accurate results.

5. Frequently Asked Questions (FAQ)

Q1: What is considered high CVD risk?
A: Generally, ≥10% 10-year risk is considered high, ≥7.5% is intermediate, and <7.5% is low risk, though thresholds may vary by guidelines.

Q2: How often should CVD risk be assessed?
A: Every 4-6 years in adults 40-75 years without known CVD, or more frequently if risk factors change significantly.

Q3: What are the limitations of this calculator?
A: May be less accurate in very young/old individuals, those with established CVD, or with extreme risk factor values.

Q4: Should family history be considered?
A: Yes, family history of premature CVD is an important additional risk factor not included in all calculators.

Q5: Can lifestyle changes affect my risk?
A: Absolutely. Smoking cessation, healthy diet, regular exercise, and weight management can significantly reduce CVD risk over time.
