目的：探讨急性心肌梗死(AMI)时患者心电图对应导联ST段压低（STD）的临床意义。方法82例AMI患者根据心电图是否合并STD分为STD组(n=39)及NSTD组(n=43)，分析两组患者冠脉受累支数、肌钙蛋白Ⅰ(cTnⅠ)、肌酸激酶同工酶(CK-MB)、血沉(ESR)、C反应蛋白(CRP)水平的差异。结果 STD组患者患冠脉支数显著多于NSTD组(P<0.05)；STD组cTnⅠ、CK-MB、ESR、CRP水平显著高于NSTD组(P<0.05)。结论 AMI伴有STD可提示患者受累血管范围更加广泛、心肌受损程度更加严重、炎症反应更加剧烈，因此对于伴有STD的AMI患者应给予足够重视，选择合适的治疗方案，降低病死率。

Objective To discuss the clinical significance of reciprocal ST segment depression (STD) in elec-trocardiogram (ECG) in patients with acute myocardial infarction (AMI). Methods Eighty-two patients with AMI were divided into the STD group (n=39) and the NSTD group (n=43) according to with or without STD. Then the number of coronary artery involvement, cTnⅠ, CK-MB, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) were compared between the two groups. Results The number of coronary artery involvement in the STD group was significantly more than that in the NSTD group (P<0.05). Levels of cTnⅠ, CK-MB, ESR, and CRP in the STD group was significantly higher than those in the NSTD group (P<0.01). Conclusion AMI patients with STD in-dicates wider vascular involvement range, severer myocardial injury, and more intense inflammatory reaction, which should be paid more attention to. Appropriate treatment should be applied to reduce the mortality rate.
