摘要
目的探讨T2DM患者血清胱抑素C(Cys-C)与心率变异性(HRV)的相关性。方法选取T2DM患者222例,根据Cys-C分为高Cys-C(n=112)和低Cys-C组(n=110)。免疫比浊法检测Cys-C,24h动态心电图评估HRV。结果高Cys-C组5min心搏间期均值的标准差(SDANN)低于低Cys-C组[109(89,136)vs 132(105,187)m/s,P<0.05]。多元线性回归分析显示,Cys-C(log)与SDANN(log)(β=-0.395,P<0.01)、低频/高频(LF/HF)(log)(β=-0.141,P<0.01)、总功率TP(log)(β=-0.174,P<0.01)独立相关。结论 T2DM患者血Cys-C与HRV指标(SDANN、LF/HF、TP)呈负相关,提示高Cys-C与糖尿病心脏自主神经病变(DCAN)相关。
Objective To investigate the relationship between serum cystatin C(Cys-C)and heart rate variability(HRV)in patients with type 2diabetes mellitus(T2DM). Methods 222T2 DM patients were enrolled in this cross-sectional study.Patients were divided into two groups according to the levels of serum Cys-C:the higher group(n=112)and the lower group(n=110).Serum Cys-C was determined by immune-turbidimetric method.24-h Holter monitoring was performed for HRV analysis. Results The higher Cys-C group had less SDANN than the lower Cys-C group[109(89,136)vs 132(105,187)m/s,P〈0.05].In multiple linear regression,Cys-C(log)was independently associated with SDANN(log)(β=-0.395,P〈0.01),LF/HF(log)(β=-0.141,P〈0.01)and TP(log)(β=-0.174,P〈0.01).Conclusion Reduced HRV parameters(SDANN,LF/HF,TP),which reflect cardiovascular autonomic imbalance,are closely related to serum Cys-C in T2 DM.These findings means high level of Cys-C is associated with DCAN(diabetic cardiac autonomic neuropathy).
