摘 要:目的 探讨左卡尼汀对终末期肾病维持性血液透析患者心脏结构的影响.方法 选择2013年6月至2014年6月于北京军区总医院行规律性血液透析的终末期肾病合并慢性心功能不全患者60例.采用随机数字表法分为观察组和对照组,每组30例.对照组采用常规血液透析治疗,3次/周,4h/次,常规控制血压、纠正贫血、改善钙磷代谢紊乱、扩张冠状动脉、强心等治疗.观察组在对照组治疗方案的基础上,在每次透析结束前从患者内瘘静脉端注射稀释于20 ml 0.9%氯化钠注射液中的左卡尼汀1 g.2组患者疗程均为3个月,疗程结束后,重新评定心功能分级.结果 观察组总有效率明显高于对照组[90.0%(27/30)比63.3%(19/30)],差异有统计学意义(P<0.05).观察组治疗后左心室收缩末期内径(LVESD)、左心室舒张末期内径(LVEDD)、左心室射血分数(LVEF)、心脏指数及最大血流速度比(E/A)明显改善,差异有统计学意义[(46 ±6)mm比(50±6) mm,(50.9±7.2) mm比(58.9±8.8)mm,(43±3)%比(36±4)%,(2.1±0.6)L/(min ·m2)比(1.6±0.6)L/(min·m2),(0.98±0.18)比(0.69 ±0.13),均P<0.05];对照组治疗前后LEVDD、LVEF、心脏指数及E/A明显改善,差异有统计学意义[(57.2±2.1)mm比(60.3±2.4) mm,(42±3)%比(37±4)%,(2.0±0.8)L/(min·m2)比(1.4±0.6)L/(min· m2),(0.94 ±0.15)比(0.67 s0.12),均P<0.05].且观察组LVESD、LVEDD明显低于对照组,LVEF明显高于对照组,差异有统计学意义(P<0.05).结论 终末期肾病维持性血液透析合并心功能不全患者在常规治疗基础上联合左卡尼汀可以有效改善透析患者的心力衰竭情况,治疗效果增强,且安全有效.Objective To investigate the effect of levocarnitine on cardiac structures in hemodialysis patients of end-stage renal disease.Methods Totally 60 patients of end-stage renal disease complicated with cardiac insufficiency undergoing regular hemodialysis from June 2013 to June 2014 were enrolled and randomly divided into observation group and control group (30 cases in each group).Control group was given conventional hemodialysis (3 times/week,4 h/time) and conventional therapy including controlling blood pressure,correcting anemia,improving calcium and phosphorus metabolism,dilating coronary and cardiotonic treatment;observation group was given levocarnitine 1 g (diluted in 20 ml of 0.5% sodium chloride,injection from the arteriovenous internal fistula before the end of hemodialysis).The treatment lasted for 3 months.Before and after treatment,the heart function classification was assessed and compared between the two groups.Results The clinical effective rate in observation group was significantly higher than that in control group [90.0% (27/30) vs 63.3% (19/30)] (x2 =6.22,P 〈 0.05).The left ventricular end-systolic diameter (LVESD),left ventricular end-diastolic diameter (LVEDD),left ventricular ejection fraction (LVEF),cardiac index (CI) and mitral valve peak early diastolic blood flow velocity/mitral valve late diastolic flow velocity (E/A) ratio were all significantly improved after treatment compared with those before treatment in observation group [(46 ±6) mm vs (50 ±6) mm,(50.9 ± 7.2) mm vs (58.9 ±8.8) mm,(43 ±3)% vs (36 ± 4)%,(2.1 ±0.6) L/(min · m2) vs (1.6 ± 0.6) L/(min·m2),(0.98±0.18) vs (0.69±0.13)] and control group [(57.2±2.1) mm vs (60.3 ± 2.4) mm,(42±3)% vs (37±4)%,(2.0± 0.8) I/(min · m2) vs (1.4± 0.6) L/(min · m2),(0.94± 0.15) vs (0.67 ± 0.12)] (P 〈 0.05).The LVESD,LVEDD were significantly lower,the LVEF was significantly higher in observ
