A newer medical term is drawing attention to a health problem that is familiar to many Americans, even if the name is not: cardiovascular-kidney-metabolic syndrome.
Known as CKM syndrome, the condition is not a single disease. It is a framework for understanding how heart disease, kidney disease and metabolic disorders such as Type 2 diabetes and obesity frequently overlap and worsen one another. Recent reports have highlighted research suggesting that a large majority of U.S. adults fall somewhere on the CKM spectrum, from early risk factors to advanced disease.
The American Heart Association introduced the term to encourage doctors and patients to look at these conditions together rather than as separate problems. High blood pressure can strain the heart and kidneys. Kidney dysfunction can increase cardiovascular risk. Insulin resistance, excess weight and abnormal cholesterol can accelerate both. Over time, the combination can raise the risk of heart attack, stroke, heart failure and chronic kidney disease.
What the CKM label is meant to do
Clinicians say the point of CKM syndrome is not to create a frightening new diagnosis, but to improve prevention. The framework groups patients by stages, beginning with people who have no apparent risk factors and moving through early metabolic risk, kidney disease or cardiovascular disease, and then to more advanced illness.
For many patients, the earliest warning signs may be common findings from a routine checkup: elevated blood pressure, higher blood sugar, excess abdominal weight, abnormal cholesterol or early changes in kidney function. Those measurements can help clinicians identify people who may benefit from earlier intervention.
The approach also reflects a shift in how major chronic diseases are treated. A patient with diabetes may need kidney monitoring and cardiovascular risk assessment. A patient with kidney disease may need careful blood pressure control and screening for heart problems. A patient with obesity may need support that includes nutrition, physical activity, medication when appropriate and evaluation for related complications.
Why many people may not recognize the risk
Part of the challenge is that early CKM risk often develops silently. High blood pressure and early kidney disease may have no noticeable symptoms. Prediabetes can go undetected for years. Some people do not learn they have overlapping risk until they experience chest pain, shortness of breath, swelling, fatigue or an abnormal lab result.
Public health experts say the broad reach of CKM syndrome reflects long-running trends in the United States, including high rates of obesity, sedentary behavior, diabetes and hypertension. Age, family history, access to health care, diet, smoking and socioeconomic factors also influence risk.
Doctors generally recommend that adults discuss blood pressure, cholesterol, blood sugar and kidney function testing with a health professional, especially if they have a family history of heart disease, diabetes or kidney disease. Lifestyle steps such as regular physical activity, a heart-healthy diet, not smoking and maintaining a healthy weight can reduce risk. Some patients may also benefit from medications that lower blood pressure, cholesterol or blood sugar and protect the heart or kidneys.
The growing use of the CKM term may help patients understand why a primary care doctor, cardiologist, endocrinologist or nephrologist may focus on the same set of numbers. The message is straightforward: the heart, kidneys and metabolism are closely connected, and preventing damage in one system may help protect the others.
Key questions
- What is cardiovascular-kidney-metabolic syndrome?
- Cardiovascular-kidney-metabolic syndrome, or CKM syndrome, is a term for the overlapping relationship among heart disease, kidney disease and metabolic conditions such as obesity, insulin resistance and Type 2 diabetes.
- How can people lower their CKM-related risk?
- Risk reduction often starts with routine screening for blood pressure, cholesterol, blood sugar and kidney function, along with regular physical activity, a balanced diet, not smoking and medical treatment when recommended by a clinician.
