Nearly 9 in 10 Americans Have a Hidden Heart-Kidney-Metabolic Risk. Here's What the New Guidelines Say
A new clinical guideline from major medical organizations reveals that nearly 90% of U.S. adults have at least one risk factor for cardiovascular-kidney-metabolic (CKM) syndrome, an interconnected set of health conditions that significantly increase the risk of heart disease, stroke, and kidney failure. The first-ever guideline on CKM syndrome, published by the American Heart Association and the American College of Cardiology, emphasizes that these conditions don't occur in isolation and calls for earlier screening and coordinated care to prevent serious complications.
What Is Cardiovascular-Kidney-Metabolic Syndrome?
CKM syndrome represents a shift in how doctors understand heart disease. Rather than treating high blood pressure, high cholesterol, diabetes, and kidney disease as separate problems, the new guidelines recognize them as deeply connected conditions that amplify each other's risk. Common risk factors include excess weight, high blood pressure, abnormal lipids (cholesterol and triglycerides), high blood glucose, and reduced kidney function.
The scope of the problem is substantial. According to the guidelines, 40% of U.S. adults and 21% of children and adolescents have obesity, defined as excess body fat that presents a risk to health. Obesity is a major driver of high blood pressure, Type 2 diabetes, metabolic dysfunction, cardiovascular disease, and kidney disease.
"Heart, kidney, and metabolic conditions don't occur in isolation,they are deeply connected. This guideline calls for earlier screening and care, focusing on prevention and coordinated action to reduce the risk of cardiovascular disease before serious complications develop or a major cardiac event occurs," said Chiadi E. Ndumele, M.D., Ph.D., M.H.S., FAHA, chair of the guideline writing committee and the director of obesity and cardiometabolic research at Johns Hopkins School of Medicine.

How Are the Four Stages of CKM Syndrome Defined?
The guideline introduces a four-stage framework to help doctors identify risk early and tailor prevention strategies. This staging system allows clinicians to slow or even reverse the progression of CKM syndrome before serious complications develop.
- Stage 1: Individuals with overweight or obesity or prediabetes, but without other metabolic risk factors, kidney disease, or cardiovascular disease
- Stage 2: People with one or more metabolic risk factors such as high blood pressure, abnormal lipid levels, Type 2 diabetes, or metabolic syndrome, and/or kidney disease, but without cardiovascular disease
- Stage 3: People with subclinical (asymptomatic) cardiovascular disease and CKM risk factors, or those with very-high-risk chronic kidney disease or a high predicted 10-year risk of cardiovascular disease based on updated risk equations
- Stage 4: Individuals with diagnosed cardiovascular disease such as coronary heart disease, heart failure, stroke, peripheral artery disease, or atrial fibrillation, combined with overweight or obesity, other metabolic risk factors, or kidney disease
The guideline also introduces improved risk assessment using the Predicting Risk of cardiovascular disease EVENTs (PREVENT) equations, which estimate 10-year and 30-year risk for cardiovascular disease. Unlike previous tools, PREVENT includes kidney and metabolic health factors for a more comprehensive and precise estimation of risk.
How to Prevent and Manage CKM Syndrome
The guidelines emphasize that lifestyle modification can make a meaningful difference in overall health and that taking action early can help prevent a heart attack, heart failure, stroke, or kidney failure. The recommendations include:
- Lifestyle Behaviors: Regular physical activity, heart-healthy eating, maintaining a healthy weight, managing blood pressure, blood sugar, and cholesterol, avoiding tobacco, and getting enough quality sleep, all outlined in the American Heart Association's Life's Essential 8
- Screening for Social Factors: Assessment of food insecurity, housing instability, and financial strain, which can increase the risk of developing CKM syndrome
- Coordinated Interdisciplinary Care: Working with multiple healthcare providers to address heart, kidney, and metabolic health together rather than in isolation
- Medication and Surgical Options: In conjunction with lifestyle management, medications to manage blood pressure, cholesterol, blood sugar, and weight to protect the heart and kidneys; GLP-1-based therapies (medications originally developed for diabetes) are now recommended for select individuals with obesity and/or Type 2 diabetes and other risk factors for cardiovascular disease to reduce the risk of cardiac events; metabolic and bariatric surgery may also be used to treat CKM syndrome
"Life's Essential 8 focuses on regular physical activity, heart-healthy eating, maintaining a healthy weight, managing blood pressure, blood sugar and cholesterol, as well as avoiding tobacco and getting enough quality sleep. These are all powerful tools to improve cardiovascular-kidney-metabolic health. These actions reduce the risk of heart disease and also support kidney and metabolic health across the lifespan," explained Fátima Rodriguez, M.D., M.P.H., FAHA, FACC, vice chair of the writing committee and an associate professor of cardiovascular medicine at Stanford Medicine.

Why Does This New Guideline Matter?
The development of the first-ever CKM syndrome guideline represents a major shift in how the medical community approaches cardiovascular disease prevention. By recognizing the interconnected nature of heart, kidney, and metabolic health, doctors can now identify at-risk patients earlier and intervene before serious complications develop. The guideline was developed by the American Heart Association and the American College of Cardiology Joint Committee on Clinical Practice Guidelines in collaboration with the American Diabetes Association, the American Diabetes Association Obesity Association, and the American Society of Nephrology.
For patients, the message is clear: understanding your risk factors for CKM syndrome and taking action early through lifestyle changes and working with your healthcare team can significantly reduce your chances of experiencing a heart attack, stroke, or kidney failure. The guideline emphasizes that prevention and early intervention are far more effective than treating advanced disease.
