Cardio-Renal-Metabolic Syndrome: Risks, Symptoms & Prevention

Many health concerns—diabetes, kidney disease, and high blood pressure—are often treated as separate conditions. However, the American Heart Association’s (AHA) 2026 statistical report identifies these as interconnected components of a single syndrome known as cardio-renal-metabolic syndrome (CRM). This connection represents a significant public health issue, particularly as awareness remains low: nearly one in four American adults with diabetes are unaware of their condition, and up to nine in ten adults with chronic kidney disease are undiagnosed, according to the centres for Disease Control and Prevention (CDC).

How Conditions Interrelate

The heart, kidneys, and metabolism share common risk factors, including high blood pressure, high cholesterol, high blood sugar, being overweight, and decreased kidney function. The presence of one of these conditions increases the risk of developing others. The AHA report highlights a critical gap in care: two-thirds of patients with hypertension or diabetes are unaware they also have kidney damage, often due to a lack of uACR testing—a urine analysis evaluating kidney function.

For individuals with diabetes or hypertension, the AHA recommends two key tests: the uACR urine test and the eGFR blood test, both measuring different aspects of kidney health. Currently, approximately half of American adults have hypertension, a third have high cholesterol, more than half have prediabetes or diabetes, and nearly one in seven has kidney disease.

Did You Know? Nearly 80% of heart attacks and strokes are potentially preventable, according to the American Heart Association.

“We encourage everyone to be aware of the connections between these diseases in order to think about their overall health beyond each condition taken in isolation,” explains Dr. Stacey E. Rosen, volunteer president of the American Heart Association, in a recent statement. “Better understanding these connections could lead to better prevention of complications through lifestyle changes and appropriate treatments.”

The Importance of Early Detection

The primary threats posed by the syndrome CRM are disabilities and deaths related to cardiovascular disease and stroke. However, the AHA suggests that proactive measures could significantly reduce these risks.

Diagnosis involves simple tests: blood pressure, lipid panel (total cholesterol, LDL “bad” cholesterol, HDL “good” cholesterol, triglycerides), fasting blood glucose or hemoglobin A1C, body mass index, waist circumference, and kidney tests uACR and eGFR. These results can even be integrated into the AHA’s online PREVENT calculator to estimate 10- or 30-year cardiovascular risk.

Expert Insight: Recognizing the interconnectedness of diabetes, kidney disease, and cardiovascular health is a crucial step toward more holistic and preventative care. Addressing these conditions in isolation may overlook critical opportunities for intervention.

Experts currently recommend adopting healthy lifestyle habits to prevent many of these conditions, as outlined in “Life’s Essential 8”—eight indicators to follow for a healthy heart.
