1. What is the Cardiovascular Score Risk Calculator?

The Cardiovascular Score Risk Calculator estimates the 10-year probability of developing cardiovascular disease using established risk algorithms like Framingham or QRISK3. It considers multiple risk factors including age, blood pressure, cholesterol levels, and lifestyle factors.

2. How Does the Calculator Work?

The calculator uses cardiovascular risk prediction equations:

\[ Risk \% = Framingham \text{ or } QRISK3: \text{ logistic regression on age, BP, cholesterol, etc.} \]

Where:

\( Age \) — Age in years
\( BP \) — Systolic blood pressure in mmHg
\( Cholesterol \) — Total cholesterol in mmol/L
Gender — Male or female
Smoking status — Current smoker or non-smoker
Diabetes status — Diabetic or non-diabetic

Explanation: The equation uses logistic regression to calculate the 10-year probability of cardiovascular events based on multiple risk factors.

3. Importance of Cardiovascular Risk Assessment

Details: Accurate cardiovascular risk assessment helps identify individuals at high risk for preventive interventions, guides treatment decisions for blood pressure and cholesterol management, and supports shared decision-making between patients and healthcare providers.

4. Using the Calculator

Tips: Enter age in years, systolic blood pressure in mmHg, cholesterol in mmol/L, and select appropriate options for gender, smoking status, and diabetes. All values must be valid and within reasonable ranges.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between Framingham and QRISK3?
A: Framingham was developed in the US population, while QRISK3 is UK-based and includes additional factors like ethnicity, deprivation, and chronic conditions.

Q2: What is considered high cardiovascular risk?
A: Generally, ≥10% 10-year risk is considered intermediate, ≥20% is high risk. However, thresholds may vary by guidelines.

Q3: How often should cardiovascular risk be assessed?
A: For adults without known CVD, assessment every 4-6 years is recommended, or more frequently if risk factors change.

Q4: Are there limitations to these risk scores?
A: Yes, they may underestimate risk in young people with multiple risk factors and overestimate in older adults. They don't account for all risk factors like family history or novel biomarkers.

Q5: Should treatment decisions be based solely on risk scores?
A: No, risk scores should inform but not replace clinical judgment. Individual patient factors, preferences, and additional testing should guide final decisions.
