Background
Cardiac arrhythmias are common in CKD and may accelerate renal function decline via heart–kidney crosstalk. Premature ventricular complexes (PVCs), prevalent in CKD, may worsen renal function by reducing cardiac output and impairing renal perfusion. CKD promotes PVCs through electrolyte imbalance, fibrosis, and uremia, while high PVC burden is linked to ventricular dysfunction. Despite known cardiovascular risks, the impact of PVCs on CKD progression remains underexplored.
Methods
We conducted a multicenter retrospective cohort study of 1,804 CKD 3b–4 patients from Taiwan's pre-ESRD program (2009–2021) who underwent 24-hour Holter monitoring. High PVC burden was defined as >30 PVCs/hour. The primary outcome was a kidney-specific composite of (1) ≥40% decline in eGFR from baseline (2) progression to ESRD, defined as sustained eGFR <10 mL/min/1.73 m2 or initiation of maintenance dialysis. The secondary outcome was the kidney-specific composite plus all-cause mortality. Annual eGFR decline was analyzed using linear mixed-effects models.
Results
Mean age was 68.2±11.3 years; baseline eGFR was 34.8±12.1. High PVC burden was associated with increased risk of the primary outcome (HR 1.349; 95%CI 1.094–1.662; p=0.005), consistent in competing risk analysis (HR: 1.269; p=0.026). Annual eGFR decline was greater in high-burden patients (−0.85mL/min/1.73 m2/year; p<0.001).
Conclusion
High PVC burden independently predicts accelerated renal function decline and adverse renal outcomes in advanced CKD. It may guide early renal risk stratification and prompt PVC-targeted intervention.
