In June 2026, the American Heart Association and the American College of Cardiology, together with the American Diabetes Association and the American Society of Nephrology, released the first joint guideline on cardiovascular-kidney-metabolic (CKM) syndrome.
The core message is simple. Nearly 90% of US adults carry at least one CKM risk factor, yet the heart, kidneys and metabolism have long been treated as separate departments.
An NHANES analysis of 34,809 US adults found that only 13.2% sit at Stage 0, meaning fully healthy weight, normal blood sugar, normal blood pressure, normal lipids and normal kidney function. Everyone else has already slipped one or more steps up the ladder, often without knowing it.
Awareness is thin. In an August 2025 survey of about 4,000 adults, only 12% had heard of CKM health or CKM syndrome, and 68% still believed that heart, kidney and metabolic problems should be managed separately.

What CKM syndrome actually is
CKM syndrome describes the tight, two-way traffic between three systems. Excess or dysfunctional fat tissue drives insulin resistance. Insulin resistance raises blood sugar and blood pressure. High blood pressure and blood sugar damage the tiny filters in the kidneys. Failing kidneys, in turn, accelerate heart disease. A problem in one place quietly worsens the others.
That is why the 2026 guideline treats a single risk factor as a warning sign, not a footnote. Prediabetes, early kidney disease, elevated blood pressure, abnormal cholesterol or excess weight around the middle is enough to place a person inside the framework.
"Heart, kidney, and metabolic conditions don't occur in isolation," said Chiadi E. Ndumele, M.D., Ph.D., M.H.S., FAHA, of Johns Hopkins, who chaired the guideline writing committee. He called for earlier screening and a focus on prevention.
The five stages, from healthy to advanced disease
The AHA describes CKM health across five stages. Stage 0 is a clean baseline, with no risk factors. Stage 1 adds excess or dysfunctional body fat, insulin resistance or prediabetes. Stage 2 layers on metabolic risk factors such as high blood pressure, high triglycerides, type 2 diabetes or chronic kidney disease.

Stage 3 shows silent damage to the heart, kidneys or blood vessels on imaging or lab tests, but without symptoms. Stage 4 is diagnosed cardiovascular disease, sometimes together with kidney failure. People can move up or down the ladder. Early detection and treatment can slow, and in some cases reverse, damage.
What to do at each stage
The guideline places lifestyle at the center at every stage. It points to the AHA's Life's Essential 8: regular physical activity, a heart-healthy eating pattern, a healthy weight, controlled blood pressure, healthy cholesterol, healthy blood sugar, avoiding tobacco and adequate sleep. Those match the same everyday levers already shown to matter for metabolic risk.
For the first time, the guideline also recommends GLP-1 therapies for selected patients with obesity or type 2 diabetes who meet certain criteria, and formally includes metabolic and bariatric surgery as an option in advanced cases. Risk assessment moves to the PREVENT equations, which fold in kidney and metabolic markers alongside classic heart risk factors.
Screening at any stage should include blood pressure, a lipid panel, blood sugar and two kidney tests: urine albumin-to-creatinine ratio (UACR) and estimated glomerular filtration rate (eGFR). Anyone with a single risk factor, or a family history of heart, kidney or metabolic disease, should ask a clinician which of those numbers to check next.
