(Press-News.org) CLEVELAND—Researchers at Case Western Reserve University, University Hospitals and Houston Methodist will harness the power of artificial intelligence (AI) to more accurately predict risk of heart failure and other cardiovascular events, including estimating when an adverse event might occur, by developing an AI model that “learns” from patient scans.
Cardiovascular disease is the leading cause of death worldwide, claiming over 17 million lives every year, according to the American Heart Association. Accurately identifying individuals at high risk remains a crucial unmet need. This initiative bridges the gap by developing advanced AI tools to analyze images from calcium-scoring computed tomography (CT) scans, a widely used diagnostic tool. The scans, which indicate how much plaque is in a patient’s arteries, also contain information about the aorta, heart shape, lung, muscles and liver.
The National Institutes of Health awarded two grants, totaling $4 million, to the collaboration to develop the AI model.
“This project represents a significant leap forward in personalized healthcare,” said project leader Shuo Li, a Case Western Reserve professor of biomedical engineering and computer and data sciences. “It has the potential to set new standards for cardiovascular disease prevention and management, as well as advance the forefront of using AI to analyze images for transformational healthcare.”
Innovative approach to predicting heart failure
The project creates AI-driven predictive models capable of interpreting combined data from calcium-scoring CT scans, clinical risk factors and demographics. Led by Li and Sadeer Al-Kindi, an imaging cardiologist and associate professor of cardiology at Houston Methodist DeBakey Heart and Vascular Center, the team aims to uncover deeper insights into the interplay between heart health and body composition. This would allow clinicians to identify at-risk patients with unprecedented accuracy.
“Accurate risk prediction allows us to tailor preventative treatments, reducing the burden of cardiovascular diseases and improving patient outcomes,” Al-Kindi said. “By identifying risk of heart failure and other events early, this project can potentially redefine care protocols, save lives and lower healthcare costs.”
Seamlessly adding AI to a clinician’s toolkit
By leveraging existing screening CT data in two large health systems (Houston Methodist and University Hospitals), this research underscores the potential of AI to address longstanding clinical challenges in a cost-effective and scalable way.
“Our goal is to develop a non-invasive, accurate and personalized method for predicting cardiovascular disease risk,” Li said. “This innovation will seamlessly integrate into existing clinical workflows, enhancing decision-making while minimizing the need for invasive diagnostic procedures.”
Using low-cost, non-invasive screening
A calcium-scoring CT is a low-cost, non-invasive heart scan that identifies how much calcified plaque is in the coronary arteries. The plaque in heart’s arteries can narrow or block them and can predict someone's risk of heart attack.
The AI model will learn to extract novel insights from CT images and use these measurements to estimate risk of cardiovascular events in large cohorts. These measurements include coronary calcium, heart shape, body composition, bone density and visceral fat in addition to age and other factors. AI can correlate outcomes with these risk factors much faster and more comprehensively.
“A clearer understanding of how these novel imaging-based risk factors combine will advance the knowledge of cardiometabolic disease phenotypes and support doctors in making appropriate and timely therapeutic recommendations,” said Sanjay Rajagopalan, a professor and director of the Cardiovascular Research Institute at the Case Western Reserve University School of Medicine and chief of cardiovascular medicine at University Hospitals Harrington Heart & Vascular Institute.
The research team includes other key contributors from diverse disciplines at Case Western Reserve: David Wilson, the Robert Herbold Professor of biomedical engineering and radiology and Pingfu Fu, professor of biostatistics in the Department of Population and Quantitative Health Sciences at the medical school.

HKU ecologist highlights critical gaps in global wildlife trade monitoring
2025-01-14
Wildlife trade poses one of the greatest threats to the survival of numerous species. According to the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) at least 50,000 species are involved in trade. However, while this figure already seems huge, it risks overlooking less traditional sectors of wildlife trade, such as the pet or fashion trade. For instance, recent data shows that the number of butterflies traded exceeds the total number of terrestrial arthropods in the IPBES assessment. This raises a critical question: How many ...
Smoking may lead people to earn less
2025-01-14
A new paper in Nicotine & Tobacco Research, published by Oxford University Press, finds that smoking has a negative effect on earnings among younger workers. This is particularly true among the less well educated.
The adverse health effects of smoking are well known. Smoking increases the risk of various cancers, respiratory issues, and cardiovascular diseases, with approximately 14% of all deaths in 2019 attributed to smoking. Despite smoking rates declining since the 1990s, in 2019 18% of women and 27% of men in high income countries still smoked.
Tobacco smoking has ...
Hiroshima flooding: A case study of well usage and adaptive governance
2025-01-14
Society is often vulnerable to disasters, but how humans manage during and after can turn devastation into opportunities for improved resilience.
For instance, private wells are attracting attention as an alternative resource for securing water for daily use and consumption in the event the water supply is cut off after a disaster. However, there are few records on how wells are used in the confusion of disasters, so detailed research is needed to promote the use of emergency wells.
Professor Takahiro Endo of the Graduate School of Sustainable System Sciences at Osaka Metropolitan University conducted a survey on the use ...
New survey finds over half of Americans are unaware that bariatric surgery can improve fertility
2025-01-14
St. Petersburg, Fla - Welcoming a newborn is something many couples dream of doing, but it can get complicated when conceiving becomes a roadblock. Infertility affects one in six people, but obesity can also be a problem. When diet and exercise aren’t enough to lose weight, bariatric surgery can become an option. Yet a new national survey by Orlando Health finds that 56% of Americans do not know that bariatric surgery is an effective way to improve fertility.

Applications of ultrafast nano-spectroscopy and nano-imaging
2025-01-14
Optical microscopy has long been a fundamental tool for scientific discovery. Yet, traditional far-field techniques are limited by diffraction, restricting their resolution to hundreds of nanometers, which can be inadequate for capturing phenomena in quantum and solid-state materials. With the emergence of tip-based microscopy capable of achieving atomic-scale spatial resolution, near-field optical nano-spectroscopy and nano-imaging have evolved into versatile tools for characterizing the optical properties of materials at the nanoscale. When further combined with ultrafast pump-probe ...

2025-01-14
Communities exposed to drinking water contaminated with manufactured chemicals known as per- and polyfluoroalkyl substances (PFAS) experience up to a 33% higher incidence of certain cancers, according to new research from the Keck School of Medicine of USC.
The study, funded by the National Institutes of Health and just published in the Journal of Exposure Science and Environmental Epidemiology, is the first to examine cancer and PFAS contamination of drinking water in the U.S.
PFAS, which are used in consumer products such as furniture and food packaging, have been found in about 45% of drinking water supplies across the United States. ...
Scientists explain how a compound from sea sponge exerts its biological effects
2025-01-14
Girolline, a compound extracted from the sea sponge Pseudaxinyssa cantharella, has been investigated for possible antitumor effects and also found to have anti-malarial effects. Now, thanks to work by scientists from the RIKEN Center for Sustainable Resource Science, researchers have a better idea of how it works. In addition to its possible medicinal properties, the current findings suggest that the compound could also be useful as a chemical probe for research in areas such as aging and mitochondrial health.
GIrolline is one of a number of compounds with biological functions that were isolated from Pseudaxinyssa ...
