New Blood Test Spots Hidden Heart Risks up to 15 Years Early
Summary
Researchers at The University of Hong Kong created an AI-powered blood test called CardiOmicScore that can predict a person's risk of six major heart and blood vessel diseases up to 15 years before symptoms appear. The test analyzes proteins and small molecules in the blood to provide a current picture of health, rather than relying on fixed genetic information.Key Facts
- CardiOmicScore predicts risks for coronary artery disease, stroke, heart failure, atrial fibrillation, peripheral artery disease, and venous thromboembolism.
- It uses data from one blood sample, analyzing thousands of proteins and metabolites.
- The test detects warning signs long before traditional methods that focus on age, blood pressure, or smoking history.
- CardiOmicScore was developed using data from the U.K. Biobank with advanced AI techniques called deep learning and multiomics.
- Unlike genetic tests, which only show inherited risk, this tool reflects changes caused by lifestyle, aging, and illness.
- The test’s predictions are more accurate than conventional polygenic risk scores and improve with clinical information like age and gender.
- Cardiovascular disease caused about 19.8 million deaths worldwide in 2022.
- Early detection allows patients and doctors to take preventive steps much sooner.
