摘要 目的 探讨血管紧张素转换酶抑制剂 (ACEI)培哚普利干预慢性心衰对心肌肌浆网 (SR)Ca2 +泵活性和Ca2 +释放通道 (RyR2 )密度的影响及意义。方法 通过结扎大鼠左冠脉建立慢性心衰模型 ,以培哚普利进行干预 ,对照观察血流动力学、左室心肌SRCa2 +泵活性、[3H] ryanodine与RyR2 最大结合量 (Bmax)Kd值。结果 与对照组 (C组 )相比 ,心衰组 (F组 )LVEDP显著升高 (P <0 .0 1) ,+dp/dtmax、-dp/dtmax显著降低 (P <0 .0 1) ,培哚普利组 (P组 )LVEDP显著低于F组 (P <0 .0 1) ,+dp/dtmax、-dp/dtmax显著高于F组 (P <0 .0 1)。F组心肌SRCa2 +泵活性、[3H] ryanodine与RyR2 最大结合量Bmax显著低于C组 (P <0 .0 1) ,P组显著高于F组(P <0 .0 1) ,3组Kd值差异不显著 (P >0 .0 5 )。心肌SRCa2 +泵活性与 +dp/dtmax、-dp/dtmax显著正相关 (r =0 .5 16 1、r =0 .6 172 ,P <0 .0 1)。结论 培哚普利长期干预慢性心衰 ,能够改善心肌SRCa2 +泵活性 ,增加RyR2密度 。
