(Press-News.org) WALNUT CREEK, Calif. (July 10, 2025) – Cardiovascular disease (CVD) risk prediction models have improved the ability to stratify adults across the CVD risk spectrum. Researchers at Sutter Health and colleagues at Stanford University tested the performance of the American Heart Association’s Predicting Risk of CVD Events (PREVENT) equations in the six largest Asian subgroups as well as in Mexican and Puerto Rican Hispanic subgroups.
The findings, published June 25 in JAMA Cardiology, showed the PREVENT equations accurately predicted CVD, atherosclerotic CVD (ASCVD) and heart failure events across broad, self-identified Asian and Hispanic patient populations.
The burden of heart disease, one of the biggest health problems in the U.S., is likely to grow as the population gets older. Making sure risk tools work for all our patients is key to giving the best care possible.
Advancing Cardiovascular Health for All
“We led this study to uncover findings that may inform better cardiovascular healthcare for all. In the original validation, PREVENT equations demonstrated good discernment and calibration among racial and ethnic groups, but the model performance among Asian and Hispanic subgroups had not been previously described,” said Xiaowei (Sherry) Yan, Ph.D., senior scientist at Sutter Health’s Center for Health Systems Research and first author of the study. “Our findings showed the PREVENT models performed well across multiple subgroups, with modest variation across individual Asian and Hispanic populations.”
Study Overview
Dr. Yan and colleagues conducted an electronic health record–based retrospective cohort study of 361,778 primary care patients aged 30 to 79 years across Sutter Health — a large integrated health system in Northern California caring for more than 3.5 million patients across urban, suburban and rural communities — from January 2010 to September 2023. Patients who had at least two primary care visits during the study period were eligible for the study. Among patients who met the inclusion criteria, the mean age was 54.6 years; 53% were female; 22% were non-Hispanic Asian and 11% were Hispanic.
Key Findings
Results showed the PREVENT equations appropriately predicted risk in contemporary diverse Asian and Hispanic subgroups with modest variation in performance across the subgroups studied.
Over a mean follow-up of 8.1 years, there were 22,648 (6.3%) CVD events among study subjects.
The predictive accuracy, as demonstrated through use of statistical measures such as the C-statistic and calibration slope, was high for the outcome of total CVD among the Asian and Hispanic populations.
When examined among the subgroups studied, predictive accuracy for total CVD remained high.
There were small differences in the performance of atherosclerotic CVD and heart failure PREVENT equations among racial and ethnic groups and subgroups.
The Path Forward
“The burden of CVD and its risk factors is projected to increase across the U.S. in the coming decades, so the ability to more accurately estimate CVD risk in all the communities we serve is more critical now than ever. Although best practices for clinical implementation of the PREVENT CVD risk prediction models should be further investigated, we believe they are an important step forward for communities that have been historically underrepresented in CVD research,” said Powell Jose, M.D., FACC, Sutter Medical Group cardiologist and section chief of general cardiology for Sutter’s heart and vascular service line.
Dr. Yan, Dr. Jose and colleagues shared study limitations: they were unable to fully examine all Asian and Hispanic subgroups. Moreover, comparisons of predictive utility of PREVENT and pooled cohort equations were limited by small sample sizes in the Mexican and Puerto Rican Hispanic subgroups.
To better inform clinical application of the study findings, future work may focus on providing clinically sensible cutoffs based on PREVENT ASCVD risk to guide treatment decisions.

Researchers present BioEmu – a new AI model that rapidly and accurately predicts the full range of shapes a protein can adopt, offering a faster, cheaper alternative to traditional molecular simulations. Proteins and their complexes are essential to nearly every biological process and are central to advances in medicine and biotechnology. While recent breakthroughs in sequencing and deep learning have made it easier to determine a protein’s sequence and structure, understanding how proteins function by shifting between different shapes in response to other molecules remains a central challenge. ...
Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) is a progressive neurological disease with an average age of onset of 43 years and an average life expectancy of only 3 to 5 years after symptoms begin. ALSP is caused by microglial mutation, the immune cells of the central nervous system (CNS). Currently, ALSP has no cure and treatments are limited.
All microglia rely on a kinase called colony-stimulating factor 1 receptor (CSF1R), which is only found in microglia and other myeloid cells. When CSF1R gene carries pathogenic ...

In the tropical rainforests of Fiji, a genus of unusual plants has developed a remarkably simple but highly effective way to prevent violence between rival ant colonies: architecture.
In a new study published in Science, an international team led by Professor Guillaume Chomicki at Durham University has revealed how some species of the epiphytic plant Squamellaria (part of the coffee family, Rubiaceae) form peaceful and productive partnerships with multiple aggressive ant species simply by physically ...
Odd plants from a remote Pacific island reveal new insights into an important ecological question: how unrelated and antagonistic partners can form long-term mutualistic relationships with the same host.
Scientists studying ant plants in Fiji have discovered one way that a host plant can keep the peace among residents that might otherwise kill each other. By providing separate chambers inside a gradually enlarging tuber -- each chamber with an entry hole from the outside but no connection to any adjacent chamber -- the Squamellaria plant prevents conflicts between the multiple ant species that ...
A new study suggests that, under realistic scenarios of high emissions and socioeconomic development, annual heat-related deaths in the U.K. could rise to about 50 times current rates by the 2070s, but that climate change mitigation and adaptation could significantly limit this rise. Rebecca Cole of the London School of Hygiene and Tropical Medicine, U.K., and colleagues present these findings in the open-access journal PLOS Climate.
Heatwaves are expected to become more frequent and more intense in coming decades in the U.K. ...

(Santa Barbara, Calif.) — Rivers are Earth’s arteries. Water, sediment and nutrients self-organize into diverse, dynamic channels as they journey from the mountains to the sea. Some rivers carve out a single pathway, while others divide into multiple interwoven threads. These channel patterns shape flood risks, erosion hazards and ecosystem services for more than 3 billion people who live along river corridors worldwide.
Understanding why some waterways form single channels, while others divide into many threads, has perplexed researchers for over a century. ...
