AI study finds 42.9% of low-risk adults have hidden coronary inflammation
A U.S. study by Biograph and Caristo Diagnostics found that 42.9% of asymptomatic, low-risk adults exhibit coronary inflammation undetected by standard blood tests. The research, using AI-powered CT analysis, revealed that nearly half of participants with no visible plaque still had elevated inflammation. These findings suggest traditional cardiovascular screening may miss significant risk factors, prompting a reevaluation of preventive health protocols for apparently healthy individuals.
Key points
- Biograph, a preventive health clinic, completed a U.S. study using Caristo Diagnostics' CaRi-Heart AI technology to detect coronary inflammation in asymptomatic, low-risk adults.
- The study found that 42.9% of participants had elevated coronary inflammation, with 17.9% showing very high levels in at least one major heart artery.
- Approximately 47% of participants with no detectable coronary plaque still exhibited elevated inflammation, indicating a limitation in standard imaging and blood tests.
- The research combined high-resolution coronary computed tomography angiography with AI-enabled analysis to identify cardiovascular risk factors missed by traditional screening methods.
- The findings suggest that coronary inflammation is widespread among healthy-appearing adults, potentially altering how preventive clinics assess long-term heart disease risk.
Biograph, a preventive health and diagnostics clinic, has announced the completion of its first U.S. study utilizing Caristo Diagnostics’ CaRi-Heart technology to identify coronary inflammation in asymptomatic, low-risk individuals. The research aimed to determine the prevalence of hidden cardiovascular risk factors that standard blood tests and traditional screening methods often miss. By combining high-resolution coronary computed tomography angiography with AI-powered analysis, the study sought to provide a more comprehensive assessment of heart health in adults who appear healthy by conventional metrics.
The results indicate that coronary inflammation is far more common than previously assumed. Specifically, 42.9% of the study participants exhibited elevated inflammation levels, while 17.9% showed very high inflammation in at least one major heart artery. Notably, the study found that approximately 47% of participants with no detectable coronary plaque still had elevated inflammation, suggesting that the absence of visible blockages does not necessarily equate to a lack of underlying vascular stress. This finding challenges the reliance on plaque-based assessments for cardiovascular risk stratification.
The study, available to clinically eligible Biograph Black tier members, represents a shift toward AI-driven diagnostics in preventive medicine. By identifying inflammation in low-risk populations, the research highlights the potential for earlier intervention in heart disease prevention. While the findings are promising, they also raise questions about the clinical utility of detecting inflammation without corresponding plaque buildup, a topic likely to influence future guidelines in cardiovascular care.
