急性心肌梗死合并糖尿病患者急诊PTCA后ST段改变的临床意义

Clinical significance of resolution of ST segment elevation in acute myocardial infraction in diabetic patients after primary PTCA

目的探讨急性心肌梗死合并糖尿病患者急诊PTCA后体表心电图ST段改变的临床意义。方法回顾性总结42例急性心肌梗死合并糖尿病患者急诊PTCA术后2h心电图ST段的改变情况,分析其与PTCA效果、心肌损害程度、心功能及预后的关系。结果糖尿病并急性心肌梗死患者行急诊PTCA后体表心电图ST段回落>50%者PTCA效果好,心肌损害程度减轻,心功能较好。结论糖尿病并急性心肌梗死患者急诊PTCA后心电图ST段改变可作为判定PTCA疗效及心肌灌注情况,进而判定预后的指标之一。

Objective To investigate the clinical significance of resolution of ST segment elevation in acute myocardial infraction in diabetic patients after primary PTCA. Methods The electrocardiography of 42 diabetic patients with aeute myocardial infraction after primary PTCA were retrospectively studied, the assoeiation between resolution of ST segment elevation and efficacy of PTCA, degree of myocardial injury, myocardial function and prognosis were evaluated. Results The efficacy of PTCA was better in patients with resolution of ST segment elevation 〉 50%. Conclusion The change of ST segment elevation is important in the evaluation of PTCA efficacy and myocardial perfusion, it also could be a prognostic facto for diabetic patients with aeute myocardial infraction after primary PTCA.
