摘要 目的研究急性冠状动脉综合征(ACS)患者血浆血管生成素家族(Angs)谱序列演变及其与相关影响因子之间的关系。方法对140例ACS患者用双抗夹心酶免法和化学发光法分别测试7个时间点〔入院时(基线)、发病24 h、发病48 h、发病1 w、发病2 w和出院后发病6 w、发病18 w〕的血浆血管生成素家族(Ang-1、Ang-2、Ang-4、Tie-2)和4种相关因子基质金属蛋白酶-2(MMP-2)、B型脑钠肽(BNP)、血管内皮生长因子(VEGF)和缺氧诱导因子(HIF)-1α水平,分析ACS患者血浆Angs谱的时间-活力曲线演变关系和Angs家族与4种相关因子之间的关系。结果急性心肌梗死(AMI)血浆Ang-1和Ang-4出现初降后升演变,18 w升至AMI始点的3倍;Ang-2则先升后降变化,18 w降至正常水平;Tie-2自始至终点持续上升保持高水平。AMI发病24 h时间点Ang-1与MMP-2呈负相关(r=-0.58,P<0.001),与VEGF成微弱正相关(r=0.23,P<0.05);Ang-2和Tie-2分别与VEGF、MMP-2、HIF-1α、BNP、TNI呈正相关(P<0.05,P<0.001)。结论在ACS过程中存在着Angs谱序列演变,且与心肌坏死、炎症标志物、血管新生和心功能状态相关联。
