摘　　要：目的 :对比观察活血、益气方药对心肌梗死 (心梗 )后左心衰大鼠左心室重构的影响。方法 :采用心梗后左心衰大鼠动物模型 ,比较观察由丹参、川芎、红花组成的活血注射液和由党参、黄芪组成的益气注射液对心梗后左心衰大鼠心脏形态学结构及胶原成分、心脏湿重 /体重、左心腔面积、心梗区左室壁变薄比、单位面积内心肌细胞核数等指标的影响。结果 :活血、益气注射液组较模型组心梗健存区心肌细胞周围胶原组织明显减少 ,心脏湿重 /体重比值变小 (P <0 0 5 ) ,单位面积内心肌细胞核数明显增多 (P <0 0 5 ) ,左心腔面积明显缩小 (P <0 0 5 )。结论 :无正性肌力作用的活血注射液与益气注射液对心梗后心衰大鼠左心室重构均有一定的抑制作用。Objective: Comparative study to the effect of Chinese herbal medicine on left ventricular remodeling in rats with left heart failure after myocardial infarction (MI). Methods: Rat′s model of left heart failure after myocardial infarction was treated with injection for activating blood circulation (ABCI, consisted of R. Salviae miltiorrhizea; Rh. Ligusticum wallichii and F1. Carthamus tinctorius) and injection for replenishing Qi (RQI, consisted of R. Codonopsis Pilosulae and R. Astragalus membranaceus) respectively. The effect of treatment were evaluated by observing and comparing the changes of heart morphological structure, collagen element, heart weight/body weight ratio (HW/BW), left intraventricular area (LVA), ratio of ventricular wall thinning in MI area and myocardial nuclei number (MNN) per square area. Results: In comparison with the model group, the reduction of collagen tissue around myocardial cells in living area of MI, HW/BW and LVA of ABCI and RQI group were lower, and MNN per square area was higher significantly (all P<0 05). Conclusion: Both ABCI and RQI, though without positive myodynamia, showed certain inhibitory effect of left ventricular remodeling in rats with left heart failure after MI.
