The "Cardiovascular-Kidney-Metabolic" Era in CKD Management: Integrated Risk Factor Control and Prognostic Benefits

Area of Science:

• Nephrology
• Cardiology
• Metabolic Syndrome Research

Background:

• The Cardiovascular-Kidney-Metabolic (CKM) syndrome highlights interconnected risks.
• The impact of integrated metabolic risk factor management on cardiorenal outcomes in chronic kidney disease (CKD) patients remains incompletely understood.

Purpose of the Study:

• To quantify the association between integrated management of metabolic risk factors and cardiorenal outcomes in CKD patients.
• To identify specific combinations of risk factors that offer the most significant protection.

Main Methods:

• Retrospective cohort study of 42,763 CKD patients from the China Renal Data System (CRDS).
• Assessment of joint risk factor management based on blood pressure, glucose, low-density lipoprotein cholesterol, and BMI.
• Cox proportional hazards models used to analyze associations with cardiorenal outcomes over 64,699.25 person-years.

Main Results:

• A dose-dependent association was observed between the degree of risk factor management and reduced risks of cardiovascular disease (CVD) events and CKD progression.
• Patients managing all four risk factors showed significantly reduced hazard ratios (HR) for CVD (0.69) and CKD progression (0.79) compared to those with no management.
• Simultaneous management of blood pressure, glucose, and BMI was most protective, with HRs of 0.66 for CVD events and 0.78 for CKD progression.

Conclusions:

• Integrated management of metabolic risk factors, particularly blood pressure, glucose, and BMI, is associated with substantial reductions in cardiovascular and kidney outcomes in CKD patients.
• Findings support the CKM syndrome framework and advocate for integrated multi-target management strategies in CKD care.
