AI Links Muscle Density to Heart Health

Researchers led by the University of Edinburgh, with part-funding from the British Heart Foundation, used AI to analyze hospital scans of 1,722 patients, mostly in their 50s, who experienced chest pain. The study, published in the journal Radiology, found that individuals with greater muscle density in their chests and backs were significantly less likely to suffer a heart attack or die prematurely within a decade after their scan. This 'good-quality skeletal' muscle, characterized by higher density and lower fat content, is believed to be indicative of more physically active individuals. The AI-powered analysis, which took minutes compared to hours for a human radiologist, suggests that routine heart scans could eventually be used to identify high-risk individuals for targeted interventions like increased exercise or preventative medication. Professor Michelle Williams, a senior author, has personally adopted lifestyle changes based on the compelling results, while Professor Bryan Williams of the British Heart Foundation emphasized the power of exercise for cardiovascular health.
