New PREVENT Equations Transform Cardiovascular Risk Assessment and Personalize Hypertension Treatment
The American Heart Association's PREVENT equations provide more accurate cardiovascular disease risk predictions, enabling personalized treatment decisions for adults with high blood pressure while addressing concerns about overtreatment.
The American Heart Association's PREVENT equations offer significant advancements in cardiovascular risk assessment, providing more accurate estimates and supporting personalized treatment approaches for adults with hypertension. According to a new scientific statement published in Circulation, Hypertension, and JACC, these equations represent a major improvement over previous risk models by incorporating broader clinical factors and modern data.
The PREVENT equations, developed in 2023, estimate 10- and 30-year risk for total cardiovascular disease, including atherosclerotic cardiovascular disease and heart failure in adults aged 30-79 without prior CVD history. Unlike the previous Pooled Cohort Equations, PREVENT utilizes clinical factors such as body mass index, blood pressure, diabetes status, and adverse social factors including a zip code-based social deprivation index. Built on data from over 6 million diverse U.S. adults, the calculator offers broader applicability and more comprehensive risk assessment.
The 2025 AHA/ACC High Blood Pressure Guideline newly recommends using the PREVENT equations to personalize care, establishing a specific risk threshold for treatment initiation. The guideline indicates that people with stage 1 hypertension and a PREVENT 10-year cardiovascular disease risk score of ≥7.5% should begin blood pressure medication alongside lifestyle changes. This approach addresses earlier concerns about potential overtreatment while ensuring those most likely to benefit receive appropriate intervention.
Population-level analysis demonstrates that the number of people recommended for antihypertensive therapy under the 2025 guideline remains similar to the 2017 recommendations. The greater accuracy of the PREVENT equations means healthcare providers can better identify individuals who will benefit most from treatment while avoiding unnecessary medication in lower-risk patients. The equations represent the first risk tool that combines cardiovascular, kidney, and metabolic health measurements to support primary prevention-focused treatment decisions.
Daniel W. Jones, M.D., FAHA, chair of the 2025 high blood pressure guideline writing committee, emphasized that the PREVENT equations are based on more contemporary datasets and include information about kidney disease and metabolic disease, both linked to blood pressure levels. The tool provides stronger and more accurate risk prediction, allowing for truly personalized care. Additional resources and implementation support are available through the Association's educational materials and professional guidelines.
