摘要 目的研究选择性血管紧张素Ⅱ受体1拮抗剂(AR1B)、血管紧张素转化酶抑制剂(ACEI)对心肌梗死(MI)后心肌胶原重构的影响。方法新西兰大白兔心梗后随机分组用Valsartan治疗(V组)、Enalapril治疗(E组)或不治疗(C组),并设假手术组(S组)。治疗10周后测量血流动力学参数、胶原含量。结果MI后10周C组梗死区和非梗死区胶原含量明显高于S组。V,E组中上述指标显著下降,但仍高于S组。非梗死区胶原含量与左室舒张末压呈明显正相关。结论①在家兔心梗后早期应用Valsartan,Enalapril能改善血流动力学、抑制心肌纤维化;②非梗死区胶原沉积是降低心功能的主要因素之一。非梗死区胶原含量与左室舒张末压有明显相关性。
