ABSTRACT
Objective:
To investigate the association between ambulatory arterial stiffness index (AASI) and renal poor prognosis in patients with chronic kidney disease (CKD).Methods:
A prospective study was conducted to enroll 117 non-dialysis patients with CKD who volunteered for receiving ambulatory blood pressure monitoring test from December 2017 to December 2018 in the Department of Nephropathy of the First Medical Center of Chinese PLA General Hospital. According to the AASI tertiles, patients were divided into low AASI group (≤0.414, n=38), medium AASI group (0.414-0.517, n=40), and high AASI group (≥0.517, n=39). The differences of clinical baseline information among the three groups were compared. The follow-up time was until August 2020. Kaplan-Meier curve and Cox proportional hazard regression model were used to explore the effect of AASI on renal poor prognosis.Results:
The median age of 117 patients was 61(49, 65) years old. There were 80 males (68.4%) and patients with hypertension accounted for 77.8%(91 cases). After a median follow-up of 27 months, 34 cases had composite endpoint events [renal replacement therapy (dialysis or kidney transplantation), 40% estimated glomerular filtration rate (eGFR) decline, and death], of which 10 patients were on dialysis, 19 patients had 40% eGFR decline, and 5 patients died. There were significant differences in age, hemoglobin, body mass index, eGFR, 24 h systolic blood pressure (SBP), daytime SBP, nighttime SBP, morning SBP, 24 h mean arterial pressure and 24 h pulse pressure among the three groups (all P<0.05). Kaplan-Meier survival analysis indicated that higher AASI was associated with lower cumulative survival rate in patients (Log-rank test χ2=13.111, P=0.001). Univariate Cox regression analysis showed that high AASI was an influencing factor for renal endpoint events ( P<0.05), and after adjusting for age, gender, mean arterial pressure, eGFR, 24 h urine protein, diabetes and body mass index, high AASI was an independent influencing factor for renal poor prognosis in classification and continuous variable analysis models ( HR=2.88, 95% CI 1.00-8.26, P=0.050; HR=1.50, 95% CI 1.02-2.21, P=0.039).Conclusion:
High AASI is an independent influencing factor for renal poor prognosis in CKD patients.
