Silent Killer: How CKM Syndrome Links Heart, Kidney and Metabolic Risks

A dangerous link between heart disease, kidney problems and metabolic disorders is putting millions at risk. Known as cardiovascular-kidney-metabolic (CKM) syndrome, this condition is now considered one of the biggest public health threats due to its role in disability and early death. Experts warn that many people remain unaware of the connection, despite the high prevalence of its risk factors.

The numbers reveal a widespread issue. Around half of all U.S. adults have high blood pressure, while one in three struggles with high cholesterol. More than half the population has prediabetes or diabetes, and over half carry excess weight around the waist. Kidney disease affects about one in seven adults, yet two-thirds of those with high blood pressure or diabetes do not know they also have kidney problems. This lack of awareness often stems from missing a simple urine test called uACR, which checks kidney function.

Screening for CKM syndrome involves straightforward tests: blood pressure checks, cholesterol and blood sugar measurements, weight and waist assessments, and kidney function tests using both uACR and eGFR. Early detection is crucial, as roughly 80% of heart attacks and strokes could be prevented with timely intervention. Healthcare providers can also use the PREVENT online tool to estimate a patient's 10- or 30-year risk of heart disease based on these results.

The American Heart Association's Cardiovascular-Kidney-Metabolic Health Initiative aims to tackle this problem head-on. By raising awareness and improving diagnosis rates, the campaign expects to reach over 250,000 patients. The condition is both preventable and treatable through healthy habits—such as those outlined in Life's Essential 8—and evidence-based treatments that address multiple health issues at once.

The American Heart Association is urging people to recognise the links between these conditions. Better awareness, regular screenings, and lifestyle changes can significantly reduce complications. With proper management, many cases of CKM syndrome can be controlled or even avoided.
