摘要 回顾性分析2014年3月至2015年4月,北京大学首钢医院经冠脉造影确诊为冠心病的患者70例,其中分低龄组36例,高龄组34例,均予双联抗血小板治疗。采用血栓弹力图测定血小板抑制率,记录糖化血红蛋白(HbA1c),心肌梗死发生率等疗效及其预后。应用SPSS 15.0软件,计量资料比较采用t检验,计数资料比较采用χ~2检验,以Pearson法检验相关性,logistic回归分析行多因素分析,P<0.05为差异有统计学意义。结果显示,高龄组花生四烯酸(arachidonic acid,AA)抑制率(44.41±3.43)%,低龄组AA抑制率(43.86±3.60)%,差异无统计学意义(χ~2=-0.065,P=0.948)。高龄组二磷酸腺苷(adenosine diphosphate,ADP)抑制率(39.53±16.97)%,低于低龄组ADP抑制率(59.92±21.20)%,差异有统计学意义(χ~2=4.425,P<0.01)。两组间HbA1c差异有统计学意义(χ~2=-7.101,P=0.001),且与ADP抑制率呈负相关(r2=0.333,P<0.05)。高龄组心肌梗死11例(32.35%),低龄组4例(11.11%),差异有统计学意义(χ~2=4.686,P=0.042)。随访期间,两组首发心肌梗死时间差异有统计学意义(χ~2=5.534,P=0.011)。Logistic回归分析显示,HbA1c是老年患者氯吡格雷抵抗的独立危险因素。高龄患者氯吡格雷抵抗的发生率较高,与高龄患者血糖控制不佳相关,不良心血管事件再次发生风险较高。
