摘要(Abstract)：
目的观察冠心病(CHD)患者血浆Apelin水平的变化,探讨其与冠状动脉狭窄的关系及在冠状动脉粥样硬化中可能的作用。方法入选30例冠心病患者(CHD组);27例冠状动脉造影阴性为对照组(NC组)。两组在造影前、后及支架置入/造影后24h分别经肘静脉、股动脉途径采血;用放免法测定血浆Apelin水平。结果(1)CHD组造影后与支架置入/造影后24h血浆Apelin水平比较差异有统计学意义(动脉血浆78.11±2.84μg/L比87.83±3.43μg/L,静脉血浆77.43±2.38μg/L比85.03±2.64μg/L,P均<0.05);造影前与造影后比较差异无统计学意义。(2)CHD组动、静脉血浆Apelin水平比较差异无统计学意义。(3)NC组血浆Apelin水平在造影前、后及造影后24h差异均无统计学意义。(4)NC组与CHD组血浆Apelin水平造影前、后比较差异均有统计学意义(造影前动脉血浆90.25±2.96μg/L比77.04±3.89μg/L,静脉血浆87.83±3.34μg/L比75.14±3.16μg/L;造影后动脉血浆91.25±2.04μg/L比78.11±2.84μg/L,静脉血浆90.79±2.58μg/L比77.43±2.38μg/L;P均<0.05);支架置入/造影后24h比较差异无统计学意义。(5)CHD组血浆Apelin水平与冠状动脉狭窄的程度有负相关性(r=-0.366,P<0.05);与冠状动脉病变评分明显负相关(r=-0.467,P<0.01)。结论冠心病患者血浆Apelin水平低,介入治疗后升高;其变化与冠状动脉病变有关,提示Apelin可能参与冠状动脉粥样硬化病理生理过程。
