摘要 目的探索促红细胞生成素(EPO)对慢性心力衰竭(CHF)合并贫血患者的临床治疗作用。方法入选382例CHF合并有贫血的患者,随机分为治疗组(n=192)和对照组(n=190),对照组患者使用慢性心力衰竭常规治疗和铁剂治疗贫血。治疗组在对照组治疗方案的基础上,增加使用EPO进行治疗,治疗初期EPO的剂量为100 IU/kg,每周2次,之后再根据红细胞压积和Hb的改善情况调整剂量和注射次数。贫血指标改善后,两组患者都降低铁剂用量,而治疗组患者同时降低EPO注射次数为每月一次,剂量减为50IU/kg,持续使用半年后停用。所有患者使用铁剂的疗程不超过3个月。随访期一年,记录患者治疗前、治疗3个月后、随访期末的6min步行试验(6MWD)、EF值、Hb、随访期内不良心血管事件(CV,仅记录随访期末时数据)。结果与治疗前相比,两组患者治疗3个月后临床症状好转、各项指标均有改善,均有P<0.05。与对照组相比,治疗组患者在治疗3个月后,在6MWD、EF值、Hb三项指标上均有差异,P<0.05;在随访期末,两组患者在这三项指标上与治疗3个月时无差异,均有P>0.05,组间存在差异,P<0.05。在随访期末两组在心血管事件发生率上存在显著差异,P<0.05(对照组9.5%vs治疗组2.1%),同时在事件类型上也存在差异,P<0.05,对照组事件主要集中在"由心衰引起的住院"和"心衰加重"这两项上。结论促红细胞生成素可以改善慢性心力衰竭合并贫血患者的心功能,降低心衰复发和加重的风险,改善预后,提高生活质量,且不增加风险,安全可靠。
