Advanced Heart, Kidney, Metabolic Disease Linked to 30% Higher Cancer Risk

New research published in the American Heart Association’s journal Circulation: Population Health and Outcomes reveals that people with advanced cardiovascular-kidney-metabolic (CKM) syndrome face a 25-30% higher risk of developing cancer. The study, led by Dr. Hidehiro Kaneko from the University of Tokyo, analyzed data from nearly 1.4 million adults using national insurance claims. CKM syndrome encompasses interconnected conditions like heart disease, stroke, kidney disease, obesity, and diabetes. The American Heart Association's CKM syndrome framework stages risk from 0 (no risk factors) to 4 (established cardiovascular disease). The study found that cancer risk increased significantly only in later stages: stage 3 (25% higher) and stage 4 (30% higher), while earlier stages showed minimal increased risk. According to the American Heart Association, nearly 9 in 10 adults have at least one component of CKM syndrome, highlighting the widespread relevance of these findings.

Dr. Tochukwu Okwuosa, director of cardio-oncology at Rush University Medical Center, emphasized the bidirectional relationship: not only can cancer therapies cause heart problems, but cardiovascular risk factors also increase cancer risk. This concept of "reverse cardio-oncology" underscores the importance of healthy lifestyle choices to combat both leading causes of death in the U.S. The CKM syndrome staging framework may help identify high-risk individuals for cancer screenings. The study's authors caution that results from a Japanese population may not be fully generalizable, but prior research supports the link between metabolic dysfunction and cancer risk across populations.

The research highlights a critical intersection between chronic disease management and cancer prevention. With CKM syndrome affecting nearly 90% of U.S. adults, these findings could reshape preventive care strategies. The American Heart Association continues to promote the CKM Health Initiative to address these interconnected health threats.
