1、・340・中国医师杂志2015年3月第17卷第3期JournalofChinesePhysician,March2015,Vol.17,No.3・论著・益心泰颗粒对慢性心力衰竭兔心肌重构的影响郭志华李雅吴刚强唐云毛湘屏王月爱孙涛【摘要】目的探讨益心泰颗粒对慢性心力衰竭(CHF)兔心肌重构的影响。方法用阿霉素建立CHF家兔模型,将造模成功的家兔分为模型组、益心泰低、中、高剂量组和氯沙坦钾组;另设正常对照组。灌胃4周后观察超声心动图指标、心肌重构指标。结果与模型组比较,各用药组左心室后壁(LVPW)厚度、左心室收缩末
2、期内径(LVIDs)、左心室舒张末期内径(LVIDd)、心脏指数(CI)及左心室重量指数(LVWI)明显降低,差异有统计学意义(P<0.05,P<0.01);与模型组比较,益心泰中、高剂量组室间隔厚度(IVS)显著降低,差异有统计学意义(P<0.01)。与益心泰低剂量组比较,益心泰中、高剂量组IVS、LVPW、CI、LVWI降低,差异有统计学意义(P<0.05,P<0.01);益心泰高剂量组LVIDs及LVIDd均明显降低,差异有统计学意义(P<0.05)。结论益心泰颗粒能改善CHF兔心肌重构,且益心泰中、高剂量
3、组疗效明显优于低剂量组。[关键词]心力衰竭/病理学/中药疗法;心室重构/药物作用;心血管药物(中药)/投药和剂量EffectofYixintaigranuleonmyocardialremodelinginrabbitswithchronicheartfailureGuo**Zhihua,LiYa,WuGangqiang,TangYun,MaoXiangping,WangYueai,SunTao.TheFirstAffiliatedHospitalofHunanUniversityofTraditionalChi
