For generations, medicine has measured the body's vulnerability to heart disease through the crude lens of weight and height, missing the quieter crisis unfolding within aging muscle. Researchers at Queen Mary, University of London have now trained an artificial intelligence to read chest scans already taken by the millions, detecting the simultaneous loss of muscle and gain of fat that traditional metrics cannot see. Their study of more than 55,000 patients found that those most affected carry a 37 percent greater risk of death and a 31 percent higher chance of heart failure — a finding that

Health Insurance and Risk Management
Older patients gain access to more accurate health risk assessment, enabling early intervention and potentially reducing catastrophic health events. May increase demand for preventive healthcare services, fitness programs, and nutritional interventions, though diagnostic costs could initially burden patients without comprehensive insurance coverage.
Healthcare systems may adopt this AI tool as standard screening for elderly populations, potentially influencing insurance reimbursement policies and preventive care guidelines. Regulatory bodies may need to establish standards for AI diagnostic accuracy. Public health initiatives could prioritize sarcopenia screening and muscle-loss prevention programs, particularly in aging societies.
