Summary of the Article: New Cardiovascular Risk Assessment with PREVENT Equations
This article discusses the evolution of cardiovascular risk assessment, moving from the Pooled Cohort Equations (PCEs) to the newer Predicting Risk of Cardiovascular Disease Events (PREVENT) equations. Here’s a breakdown of the key points:
* Limitations of PCEs: The PCEs, while widely used, were criticized for both overestimating and underestimating risk in certain populations.
* Introducing PREVENT: The American Heart Association (AHA) released the PREVENT equations in 2023 to address these limitations. These equations aim for:
* More diverse and representative data.
* Inclusion of factors relevant to chronic kidney disease and heart failure.
* Assessment of risk in younger adults (starting at age 30) over a longer timeframe.
* Key Features of PREVENT:
* Larger Dataset: Derived from over 6.6 million adults.
* New inputs: Includes BMI and estimated glomerular filtration rate (eGFR) alongside traditional factors like age, cholesterol, and blood pressure.
* Social Determinants of health: Incorporates zip code via the Social Deprivation Index (SDI) to account for socioeconomic factors, replacing race as a direct input.
* Thorough Risk Assessment: Provides a composite cardiovascular disease risk, as well as individual risks for ASCVD and heart failure, for both 10- and 30-year periods.
* improved Calibration: PREVENT equations demonstrate better calibration (closer to 1.0) than PCEs, indicating more accurate risk prediction. A study showed PREVENT estimated a lower mean ASCVD risk (4.3%) compared to PCEs (8%).
* Adoption in Guidelines: The 2025 ACC/AHA High Blood Pressure Guideline now recommends using PREVENT for decision-making in Stage 1 hypertension, recommending treatment if the PREVENT composite score is 7.5% or higher. The 2025 ADA Standards of Diabetes Care recommend ASCVD risk assessment but do not specify a calculator.
* Future Outlook: PREVENT is expected to increasingly replace PCEs in clinical guidelines.
In essence, the article highlights PREVENT as a more modern, inclusive, and perhaps more accurate tool for assessing cardiovascular risk, leading to better-informed patient care.
