1. What is the QRISK3 Algorithm?

The QRISK3 algorithm estimates an individual's 10-year risk of developing cardiovascular disease (CVD) using multiple risk factors including age, cholesterol ratio, blood pressure, BMI, diabetes status, and smoking history. It provides a comprehensive assessment of cardiovascular risk.

2. How Does the Calculator Work?

The calculator uses the QRISK3 algorithm:

\[ Risk = QRISK3(Age, TC/HDL, SBP, BMI, Diabetes, Smoking, etc.) \]

Where:

\( Age \) — Age in years
\( TC/HDL \) — Total cholesterol to HDL cholesterol ratio
\( SBP \) — Systolic blood pressure (mmHg)
\( BMI \) — Body mass index (kg/m²)
\( Diabetes \) — Presence of diabetes (yes/no)
\( Smoking \) — Smoking status (yes/no)

Explanation: The algorithm incorporates multiple risk factors to provide a personalized 10-year cardiovascular disease risk assessment.

3. Importance of CVD Risk Assessment

Details: Accurate cardiovascular risk assessment is crucial for preventive care, guiding treatment decisions, and implementing lifestyle modifications to reduce future cardiovascular events.

4. Using the Calculator

Tips: Enter age in years, TC/HDL ratio, systolic blood pressure in mmHg, BMI in kg/m², and select diabetes and smoking status. All values must be valid and within reasonable ranges.

5. Frequently Asked Questions (FAQ)

Q1: What is considered a high QRISK3 score?
A: Generally, a score ≥10% indicates high risk, ≥20% indicates very high risk for cardiovascular events within 10 years.

Q2: How often should CVD risk be assessed?
A: For adults without known CVD, assessment every 4-6 years is recommended, or more frequently if risk factors change.

Q3: Can QRISK3 be used for all populations?
A: QRISK3 is validated for use in the UK population aged 25-84 years. Caution should be exercised when applying to other populations.

Q4: What factors does QRISK3 consider beyond basic parameters?
A: The full algorithm also considers ethnicity, family history, chronic conditions, and social deprivation factors.

Q5: How can I reduce my CVD risk?
A: Lifestyle modifications including healthy diet, regular exercise, smoking cessation, and managing blood pressure/cholesterol can significantly reduce risk.
