摘要 目的研究冠心病(CHD)患者冠脉不同病变程度冠脉循环中肾上腺髓质素前体N端20肽(PAMP)浓度的变化。方法用放免法分别测定不同病变程度的CHD患者与对照组外周、冠状静脉窦与主动脉根部PAMP水平,利用冠状静脉窦-主动脉根部求出经冠脉循环后心脏局部分泌并释放的PAMP水平。结果 CHD不同病变程度的患者外周血浆中PAMP水平与对照组比较差异有统计学意义(P<0.01),CHD组冠状静脉窦PAMP水平较主动脉根部及外周高(P<0.01);CHD组心脏局部PAMP浓度较对照组高(P<0.01)。结论 CHD患者血浆PAMP浓度明显增高,经冠脉循环后心脏局部有PAMP的产生。提示PAMP参与了CHD的病理生理过程,可能是机体对维持内环境稳态的一种自我保护机制,在CHD的病程发展过程中有可能是一种较为重要的血管活性物质。
