Abstract:
Objective To study the risk factors of aortic arch calcification (AoAC) in maintenance hemodialysis (MHD) patients.Methods Retrospective analysis was performed in patients who accepted MHD ≥ 5 years.The clinical data were collected.The images of plan chest radiograph detected during followup period were reviewed by certain imaging physicians,and the AoAC score was calculated.Logistic regression model analysis was proceeded to study the risk factors of AoAC.The patients were divided into AoAC positive group (29 cases) and AoAC negative group (37 cases) respectively.The clinical parameters were compared between the 2 groups.Results Sixty-six patients (21 male,45 female) were selected.The year AoAC scores from the zeroth to fifth year were (0.013 40 ± 0.074 96),(0.018 90 ± 0.078 55),(0.118 50 ± 0.170 06),(0.157 00 ± 0.207 55),(0.166 00 ± 0.205 37),(0.175 50 ± 0.222 29) scores,progressively.There were significant differences in AoAC score from the third year compared with that of the zeroth year (Z =-3.984,-4.021,-4.017;P ＜ 0.01).Logistic regression model analysis result showed that only the age of dialysis beginning was the risk factor for AoAC (relative risk 1.177,regression coefficient 0.163,P =0.002).The age of dialysis beginning,rate of diabetic nephropathy,serum calcium-phosphate product were significantly higher in AoAC positive group than that in AoAC negative group [(59.5 ± 12.6) years vs.(52.9 ± 13.2) years,27.6％(8/29) vs.2.7％(1/37),(5.81 ± 1.63) mmol2/L2 vs.(4.13 ± 0.86) mmol2/L2].Conclusions The AoAC will aggravate with the increased duration of dialysis in MHD patients.The age of dialysis beginning is the risk factor of AoAC.
