目的:比较分析阻塞性和非阻塞性冠状动脉疾病(CA)合并心肌梗死(MI)患者的内皮功能(FE)、血管壁弹性及其对年预后的影响。
材料与方法。第一阶段,选择206例诊断为心肌梗死的患者,其中103例非阻塞性冠状动脉疾病(IMBOCA)患者和103例心肌梗死合并阻塞性冠状动脉疾病(IMOCA)患者。通过随机方法选择59例患者(第一组34例,第二组25例),评估了动脉壁的FE和弹性。基线检查时,两组患者在年龄、性别、临床记忆特征以及影响预后的主要药物组的使用频率方面具有可比性。对这两类患者的年度预测进行了研究,这取决于血管壁无功能和形态变化。
结果。MBOCA患者中,在评估FE时,34例IMBOCA患者中有22例(64.7%)振幅闭塞指数(IRA)低于阈值,25例IMBOCA患者中有22例(88.0%,p<0.05)。平均IRA值分别为1.7(1.5;2.3)和1.4(1.2;1.8)(p<0.05)。两组经络间的相移值低于正常值的频率相同(88.2%和88.0%,p>0.05),该指标的平均值比较也未发现有统计学意义的差异。研究组中,计算出的增大指数(AIp75)分别为12.5(9.9;17.9)和18.8(12.9;20.8)(p>0.05)。IMBOCA组82.4%的患者血管壁弹性降低,IMBOCA组100%的患者血管壁弹性降低(p<0.05)。两组患者年内心血管事件发生率差异无统计学意义(p>0.05)。
结果。IMBOCA患者的血管壁功能变化(内皮功能障碍和血管壁弹性降低)在近2/3的病例中得到记录,但是使用IMBOCA的患者其发生频率更高(88.0%)。IMBOCA和IMOKA研究组的年预后没有差异。
