Abstract:
Objective To investigate correlation between cystatin C (Cys C) and target organ damage (TOD) in elderly hypertension and its clinical significance.Methods One hundred patients with TOD in elderly hypertension were selected as an observation group.One hundred patients without TOD in elderly hypertension were recruited as the controll group.And sixty healthy aged persons were recruited as healthy group.Serum concentration of Cys C in all cases was measured by the particle enhanced nephelometric immunoassay.At the same time,serum creatinine (Scr),urine albumin (mALB) and left ventricle mass index (LVMI) via ultrasonography were also detected.Correlation of Cys C with the above measurements were analyzed.Results The Cys C concentration was significantly higher in observation group [(1.84±0.32) mg/L] than in contrast [(0.92±0.36) mg/L] and healtbygroups [(0.85±0.34) mg/L],F=88.43,P=0.000.However,the difference in level of Cys C was not statistically significantly different between controll group and healthy group (P ＞0.05).In observation group,serum concentration of Cys C was positively correlated with Scr,mALBand LVMI (r=0.420,0.526,0.470,P=0.021,0.019,0.034) after adjusting age.Conclusions Serum level of Cys C is markedly elevated and is positively correlated with Scr,mALB and LVMI in patients with TOD in elderly hypertension.It can be considered as one of the useful factors for evaluating TOD in elderly hypertension.
