摘要
目的了解终末期肾脏病（ESRD）腹膜透析患者的心血管疾病（CVD）发病率和有关高发危险因素，以及并发CVD的腹膜透析患者治疗时需关注的问题。方法研究对象为上海交通大学医学院附属仁济医院慢性。肾脏病（CKD）5期接受腹膜透析的患者，共254例入选，采用横断面回顾性调查分析方法。平均随访时间中位数为49个月。采集病史、血生化检测结果、腹膜透析充分性评估、颈动脉及心脏彩色多普勒超声检测结果。评估CVD事件的发生、发展和预后，以及进行相关囚素分析。结果CVD事件发生率为37％（93／254）。发生CVD的患者多伴有糖尿病、透析龄较长、血三酰甘油水平较高、血清白蛋白较低、前白蛋白较低。彩色多普勒超声显示，发生CVD组的左房内径（LAD）（mm）、室间隔厚度（LVST）（mm）、左室心肌质量指数（LVMI）（g／m^2）显著高于未发生CVD组（43．16±4．93比38．02±4．77、11．19±2．05比10．01±1．45、中位数192．03比150．28，均P〈0．05）；颈动脉内膜中层厚度（IMT）较厚（中位数0．80比0．65），颈动脉内径增宽；收缩期峰值流速（SPV）和舒张期峰值流速（DV）流速降低。既往无CVD的患者在随访过程中发生CVD时，其Ccr、Kt／V、D／Pr、理想体质量校正的蛋白分解率（nPCR）及血清白蛋白水平与无发生CVD组差异有统计学意义（P=0．045、0．015、0．051、0．029及0．005）。在随访过程中出现新发CVD或CVD病情恶化的原有CVD的患者，都是透析龄较长以及三酰甘油水平较高者。LAD、LVST、LVMI及IMT在新发CVD和未发CVD两组间差异有统计学意义（P=0．033、0．022、0．045及0．029）。Kaplan—Meier生存分析显示，既往CVD史和CVD症状是生存的独立危险因素。血清白蛋白〈330g／L、LAD〉39．6mm及曾患腹膜炎的患者生存率较低。结论ESRD腹膜透析患者是CVD的高发群体，需了解这些患者的病史和伴随症状；保持透析的充分性；同时要防止腹膜炎的发生。
Objective To elucidate the prevalence and risk factors of cardiovascular disease （CVD） in end-stage renal disease （ESRD） patients on peritoneal dialysis （PD）, and to investigate the associated problems in treatment. Methods A total of 254 PD patients in our division were enrolled in this study. CVD history, laboratory measurements, examinations of carotid atherosclerosis and left ventricular hypertrophy by uhrasonography were collected and associated factors were analyzed. The median follow-up time was 49 months. Results The overall prevalence of CVD was 37% （93/254）. Diabetes, longer dialysis duration, hypertriglyceridemia, hypoalbuminemia, hypoprealbuminemia were commonly found in the patients with new CVD event. The patients without pre-existing CVD had the higher Ccr, Kt/V, D/Pr, nPCR, serum albumin level. In those with pre-existing CVD, the hypertriglyceridemia and the duration of dialysis were independent predictors of progression of CVD. Differences of LAD, LVST, LVMI and IMT were significant between with and without pre-existing CVD groups. Kaplan-Meier curves showed that the presence of CVD was the independent risk factor of survival. Alb〈330 g/L, LAD〉39.6 mm and peritonitis were risk factors of CVD. Conclusion The prevalence of CVD in PD patients is quite high. CVD history should be realized, dialysis adequacy should be maintained, and peritonitis should be prevented.
