1. What is the PREVENT Equation?

The PREVENT equation is a cardiovascular disease (CVD) risk calculator developed under the 2023 AHA guidelines. It estimates 10-year and 30-year risk for atherosclerotic cardiovascular disease using modern risk factors and biomarkers.

2. How Does the Calculator Work?

The calculator uses the PREVENT equation:

\[ Risk = f(Age, SBP, Diabetes, Smoking, TC, HDL, eGFR, etc.) \]

Where:

\( Age \) — Age in years
\( SBP \) — Systolic blood pressure (mmHg)
\( Diabetes \) — Diabetes status (yes/no)
\( Smoking \) — Smoking status (yes/no)
\( TC \) — Total cholesterol (mg/dL)
\( HDL \) — HDL cholesterol (mg/dL)
\( eGFR \) — Estimated glomerular filtration rate (mL/min/1.73m²)

Explanation: The equation incorporates traditional and novel risk factors to provide a more personalized CVD risk assessment according to the latest guidelines.

3. Importance of CVD Risk Assessment

Details: Accurate CVD risk estimation is crucial for preventive care, guiding treatment decisions, and personalizing cardiovascular health management strategies.

4. Using the Calculator

Tips: Enter all required values accurately. Use recent laboratory results for cholesterol and eGFR values. Blood pressure should be an average of multiple readings.

5. Frequently Asked Questions (FAQ)

Q1: How does PREVENT differ from previous risk calculators?
A: PREVENT incorporates newer risk factors like kidney function (eGFR) and uses contemporary population data for more accurate predictions.

Q2: What is considered high CVD risk?
A: Generally, ≥7.5% 10-year risk is considered elevated, but treatment decisions should consider individual patient factors and clinician judgment.

Q3: How often should CVD risk be assessed?
A: For adults 40-75 years without known CVD, assessment every 4-6 years is recommended, or more frequently if risk factors change.

Q4: Are there limitations to this equation?
A: The equation may be less accurate in certain populations, including those with extremely high or low risk factors, and in non-US populations.

Q5: Should treatment decisions be based solely on this calculator?
A: No, this is a tool to inform clinical decision-making, which should also consider individual patient circumstances, preferences, and other risk factors.
