摘要(Abstract)：
目的 探讨急性心肌梗死 (AMI)患者行急诊经皮冠状动脉介入术 (PCI)后ST段回落与血糖的关系。方法 入选AMI患者 80例 ,急诊入院后 90min内行冠状动脉造影示梗死相关血管前向血流TIMI 0到 1级 ,PCI后梗死相关血管前向血流TIMI恢复到 3级。术前常规心电图、生化与cTnI检查及抗栓治疗。术后 0 5h行心电图检查 ,1周后复查心电图。按血糖水平分为两组 :血糖 <8 8mmol/L(16 0mg/dl)为Ⅰ组 (41例 ) ,血糖≥ 8 8mmol/L(16 0mg/dl)为Ⅱ组 (39例 )。比较两组术前、术后及 1周时各导联ST段抬高的平均值及术前、术后ST段回落程度 ,并对其进行统计学分析。结果 Ⅱ组与Ⅰ组相比 ,术后及 1周时各导联抬高的ST段平均值及术前、术后ST段回落程度差异有显著性 ,患者既往是否有糖尿病其差异也有显著性。结论 急性心肌梗死再灌注治疗后心电图抬高的ST段回落程度受高血糖的影响。高血糖可能通过激活炎症及凝血系统 ,影响心肌的微循环灌注。
