维持性血液透析患者血清胱抑素C浓度与左心室肥厚的相关分析

比较64例维持性血液透析（MHD）患者和20例健康对照者一般临床资料和临床常用血生化指标；采用乳胶颗粒增强免疫透射比浊法检测血清胱抑素C浓度，超声心动图测定心脏腔径及心功能参数。结果示MHD患者随透析时间延长，血清胱抑素C浓度逐渐增加，且左心室肥厚发生率显著增高。左心室肥厚者收缩压、左心室重量指数和血胱抑素C浓度明显高于无左心室肥厚者。胱抑素C与左心室重量指数、收缩压相关（r=0．633，0．397，均P〈0.01）。提示MHD患者血清胱抑素C变化可能与左心室肥厚密切相关，并可能是透析患者远期心血管并发症的影响因素。

Correlation of serum cystatin C with left ventricular hypertrophy in maintenance hemodialysis patients

The clinical data and routine biochemical parameters of 64 maintenance hemodialysis (MHD)patients and 20 controls were analyzed in the study.Serum cystatin C levels were detected by latex particle enhalice inununo-turbidimetry:and the cardial structure and function were assessed by echocardiography.As MHD time extended,the levels of semm cystatin C increased gradually,accompanied with high incidence of left ventricular hypertrophy(LVH).The LVH-positive patients had higher systolic blood pressure and left veHtricular mass index,and had higher serum cystatin C than tllose in LVH-negative patients.The serum cystatin C levels were positively correlated with left yentricular mass index(r=0.633,P<0.01)and systolic blood pressure(r:0.397,P<0.01).The results suggest that serum cystatin levels may be an influencing factor for long-term cardiacvascular complication in MHD patients.
