目的:探讨经皮腔内冠状动脉介入治疗急性冠状动脉综合征前后动态心电图微伏级T波电交替的变化,分析其临床意义。方法选择急性冠状动脉综合征患者42例为研究对象,其中不稳定性心绞痛27例,为A组,急性ST段抬高型心肌梗死15例,为B组。另选择冠状动脉造影正常或者狭窄<50%的患者40例为对照组。检测三组24h动态心电图,比较微伏级T波电交替(MTWA)。结果 B组治疗前LVEF显著低于对照组(P<0.01)。治疗前,A组和B组MTWA均显著高于对照组(P<0.01或<0.05),B组显著高于A组(P<0.05)。B组术后TWA显著高于A组术后和对照组(P<0.01)。B组治疗后TWAmax较治疗前显著升高(P<0.05),余项目较治疗前显著下降(P<0.05或P<0.01)。结论 MTWA可用于急性冠状动脉综合征患者的危险分层,急性ST段抬高型心肌梗死患者在PCI治疗后,TWAmax不稳定。

Objective To discuss clinical significance of MTWA in patients with acute coronary syndrome treated by PCI. Methods Selected 42 cases with ACS were divided into group A(unstable angina, 27 cases), and group B(STEMI, 15 cases). Forty cases of normal coronary angiography or stenosis < 50% were selected as control group. 24 h Holter were detected and results of MTWA were compared. Results LVEF of B group was lower than control group before PCI(P< 0.01). Before treatment of PCI, MTWA of A and B groups were higher than control group(P<0.01 or <0.05),and that of B group were higher than A group(P<0.05). After treatment of PCI, MTWA parameters of B group were higher than control group and group A(JP<0.01). Level of TWAmax of group B after PCI was higher than that of group B before PCI (P<0.05), and other index were lower than before treatment(P<0.05 or <0.01). Conclusion MTWA can be used for risk stratification of ACS. After PCI treatment, TWAmax of patients with STEMI shows instability.
