A new clinical guideline from the American Heart Association and American College of Cardiology reveals that nearly 90% of U.S. adults have at least one component of cardiovascular-kidney-metabolic (CKM) syndrome, a condition that links heart disease, kidney disease, diabetes, and obesity together. The updated guidance offers healthcare providers a roadmap for identifying and managing this interconnected health threat before serious complications develop.

What Is Cardiovascular-Kidney-Metabolic Syndrome?

CKM syndrome is a health condition that simultaneously affects your heart, kidneys, and metabolism, which is how your body converts food and water into energy. Rather than treating these conditions in isolation, the new guideline emphasizes that they are deeply interconnected. This means that managing one condition effectively can help protect the others. The guideline was designed to help healthcare professionals identify CKM syndrome early and take appropriate action to manage and protect long-term heart, metabolic, and kidney health.

Why Should You Care About CKM Syndrome Screening?

The new guideline recommends that children, adolescents, and adults be screened for CKM syndrome risk. The goal is to classify people into CKM syndrome stages, which helps determine severity and identify the best treatment options. Early identification creates opportunities to prevent complications, stop CKM syndrome from progressing, protect kidney and heart health, and reduce the likelihood of serious cardiovascular events such as heart attack or stroke.

Adults should be routinely assessed for multiple CKM risk factors during regular healthcare visits. These assessments help catch problems before they become severe.

How to Get Screened for CKM Syndrome Risk Factors

• Kidney Function Tests: Estimated glomerular filtration rate (eGFR) and urine albumin-to-creatinine ratio (uACR) measure how well your kidneys filter waste from your blood
• Blood Sugar Assessment: Blood glucose levels or A1C tests screen for prediabetes or type 2 diabetes, which are major CKM risk factors
• Weight Measurements: Waist circumference and body mass index (BMI) checks identify obesity or being overweight as contributors to CKM syndrome
• Cholesterol and Triglycerides: A lipid panel measures abnormal cholesterol and triglycerides in your blood
• Blood Pressure Monitoring: Hypertension is a key CKM risk factor that requires regular measurement
• Liver Health Screening: FIB-4 index testing identifies fatty liver disease
• Sleep Disorder Screening: Sleep apnea and other sleep disorders increase CKM syndrome risk
• Inflammatory Condition Testing: Autoimmune or inflammatory conditions can worsen CKM syndrome

Beyond medical tests, the guideline also recommends screening for social and lifestyle factors that affect CKM syndrome risk. These include food insecurity (limited or uncertain access to quality, nutritious food), housing instability (not having a safe, reliable place to live or being at risk of losing housing), and financial difficulties. If any of these factors are identified, action should be taken to address them.

What Medications Can Help Protect Your Heart and Kidneys?

The new guideline highlights two classes of diabetes medications that offer heart and kidney protection beyond blood sugar control. Sodium-glucose cotransporter-2 inhibitors (SGLT2i) lower blood sugar by allowing the kidneys to remove excess glucose from the blood and eliminate it through urine. Glucagon-like peptide-1 (GLP-1) based therapies help the body use insulin better to lower blood sugar levels and can be effective in managing type 2 diabetes and obesity.

For people with chronic kidney disease (CKD) and diabetes or CKD with albuminuria (protein in the urine), SGLT2 inhibitors and renin-angiotensin system inhibitors (RASi) are recommended first. If albuminuria remains an issue for people with CKD and type 2 diabetes, GLP-1 based therapies or non-steroidal mineralocorticoid receptor antagonists (nsMRA) should be used for added heart and kidney protection.

Why Coordinated Care Matters for CKM Syndrome

People with more than one CKM-related condition, such as type 2 diabetes, CKD, and heart disease, need an interdisciplinary approach to their care. This means they should have a team of healthcare professionals from different specialties working together to coordinate their treatment. These specialists can include nephrologists (kidney doctors), endocrinologists (diabetes and hormone specialists), and cardiologists (heart specialists). Among this group, there should be a clear "point person" or main contact who is responsible for coordinating the patient's care.

The CKM syndrome treatment plan should be revisited at every appointment. It is important to discuss updates, understand medicines and dosages, and adjust the plan as health conditions improve or worsen. People can shift between CKM syndrome stages as their health conditions change, so regular monitoring and communication with your healthcare team are essential.

How to Address Weight and Lifestyle Factors

Obesity and excess abdominal fat are central concerns in CKM syndrome management. People should be monitored for weight-related health issues using BMI and waist size measurements, which help assess CKM syndrome risk. If a person has weight-related health issues, they should work with their clinicians to determine the best treatments and lifestyle modifications.

• Healthy Eating Pattern: Developing a nutritious diet tailored to your individual needs and health conditions
• Physical Activity and Exercise: Incorporating regular movement into your daily routine to improve metabolic health and reduce weight
• Appetite-Reducing Medications: Medicines that may decrease appetite or help with weight loss when lifestyle changes alone are insufficient
• Bariatric Surgery: Weight loss surgery when appropriate for people with significant obesity and multiple CKM-related conditions

The key takeaway from the new CKM syndrome guideline is that heart disease, kidney disease, diabetes, and obesity are not separate problems to be managed in isolation. Instead, they are interconnected components of a single syndrome that requires comprehensive, coordinated screening and treatment. By understanding your CKM syndrome risk and working with a coordinated healthcare team, you can take meaningful steps to protect your long-term health and prevent serious complications.
