BACKGROUND: Arterial stiffness is a major predictor of cardiovascular-related mortality in chronic kidney disease (CKD). While acrolein-an endogenous reactive aldehyde that accumulates with declining renal function-may be linked to vascular injury, its association with high peripheral arterial stiffness (HPAS) remains unclear.
METHODS: This cross-sectional study used the cardio-ankle vascular index (CAVI) to examine the association between serum acrolein levels and HPAS (CAVI ≥ 9.0) in 204 adults with non-dialysis CKD stages 3-5.
RESULTS: HPAS was identified in 90 patients (44.1%) and was associated with a higher prevalence of diabetes (p = 0.047), older age (p = 0.023), higher spot urine protein-creatinine ratio (UPCR, p = 0.046), higher serum fasting glucose (p = 0.041), higher interleukin-6 (p = 0.025), and higher acrolein (p = 0.008). In multivariable logistic regression analysis, serum acrolein (odds ratio, 1.015; 95% confidence interval, 1.002-1.028; p = 0.025), age (p = 0.010), and UPCR (p = 0.046) remained independently associated with HPAS. Log-transformed acrolein was positively correlated with bilateral CAVI (all p < 0.001) and log-transformed UPCR (p < 0.001) but negatively correlated with the estimated glomerular filtration rate (p = 0.001).
CONCLUSIONS: Elevated serum acrolein is independently associated with HPAS in non-dialysis CKD stages 3-5.
