摘 要:目的探讨高通量血液透析(HFD)对维持血液透析(MHD)患者的左心室结构及功能的影响及作用机制。方法选择1998年4月至2010年8月大连市中心医院血液透析中心维持性血液透析的尿毒症33例患者,于高通量透析治疗前及6个月后用超声心动图分别测定心脏结构和功能指标,包括左心房内径(LAD)、左心室舒张末期内径(LVDd)、左心室后壁厚度(LVPwT)、室间隔厚度(IVST)、舒张早期及晚期最大血流比(E/A)及等容舒张时间(IRT),并相应推算射血分数(EF),根据Devereux和Reichek公式计算左心室心肌重量指数(LVMI);同时检测甲状旁腺素(PTH)、B2微球蛋白(132一MG)、糖基化终末产物(AGEs)、白细胞介素6(IL一6)、高敏c反应蛋白(hsCRP)水平,应用SPSSl6.0统计软件比较HFD治疗前后上述指标的变化。计量资料均以z±S表示,两组间的计量资料比较采用t检验,相关性分析采用Pearson相关分析,P〈0.05为有统计学意义。结果与治疗前相比,HDF治疗6个月后IRT显著降低(118.78±16.06msVS107.5-4-13.56ms,P〈0.05),E/A升高显著升高(0.84±0.27VS0.91±0.30,P〈0.05);治疗前和HDF治疗6个月后LAD、LVDd、LVPWT、IVsT、LVEF、LVMI无统计学差异(P〉0.05)。与治疗前相比,HDF治疗6个月后132一MG、AGEs、IL一6水平显著下降,有统计学意义(P〈0.05)。结论高通量血液透析可改善MHD患者左心室的舒张功能,其机制可能与HFD清除中大分子毒素、改善MHD患者炎症状态有关。Objectives To investigate the influence of high - flux hemodialysis (HFD) on left ventricular structure and function of maintenance hemodialysis(MHD) patients and possible mechanism. Methods 33 cases with maintenance of low - flux hemodialysis in Dalian central hospital were selected, accepted HFD 6 months of treatment. Cardiac structure and function were determined by ultrasound heartbeat graph before treatment and 6 months of HFD respectively, including left atrial diameter ( LAD ), left ventricular end diastolic diameter ( LVDd ), left ventricular posterior wall thickness ( LVPWT ), interventricular septal thickness ( IVST ), early and late diastolic peak blood flow ratio ( E / A ) and isovolumic relaxation time ( IRT ), the corresponding calculation of e- jection fraction ( EF ) and the calculation of left ventricular mass index ( LVMI ) according to Devereux and Reichek formula. Parathyroid hormone ( PTH ), beta 2 microglobulin ( beta2 - MG ), advanced glycation end products ( AGEs ), interleukin 6( IL -6) and high sensitivity C reactive protein ( hsCRP ) level were measured at the same time. Further the index of left ventricular structure and function and the clinical detection of indicators were analyzed. Results After 6 months'treatment of HFD, IRT was significantly lower ( IRTll8.78 + 16.06ms vsl07.5 + 13.56ms, P 〈 0.05) ,E/A were increased significantly (0.84 + 0.27 vs0.91 + O. 30, P 〈 O. 05) , LVPWT LAD, IVST, LVEF, LVMI were no statistical difference ( P 〉 0.05 ). And beta2 - MG, AGEs, IL - 6 were significantly decreased ( P 〈 O. 05 ). Conclusions High flux hemodialysis can improve left ventricular diastolic function of patients with MHD, and its mechanism may be the effective removal of inflammatory mediators, and plas- ma middle molecule and macromolecule toxin.
