[摘要] 目的 缺血后適应对急性ST段抬高型心肌梗死(STEMI)早期心肌保护作用及预后的影响。 方法 方便选择2012年1月—2016年12月就诊于新疆生产建设兵团第四师医院并接受急症PCI治疗的急性STEMI患者60例作为该次研究对象,经随机数字表法将其分为实验组、对照组(每组30例)。对两组的再灌注心律失常(RA)、术后TIMI血流积分、无复流、急性支架内血栓、室壁运动积分、主要心血管不良事件(MACE)积分等观察指标进行统计分析。 结果 实验组RA发生率(10.00%)显著低于对照组(40.00%)(P<0.05);对照组MACE积分均值明显高于实验组(P<0.05);实验组梗死后心绞痛(13.33%)、恶性心律失常(16.67%)、心力衰竭(13.33%)等单项MACE发生率与对照组(分别为16.67%、26.67%、20.00%)对比差异无统计学意义(P>0.05)。结论 缺血后适应可降低STEMI急症介入治疗患者RA的发生率、减轻再灌注损伤,可减少心肌梗死面积及改善患者心功能,对早期心肌具有保护作用,能改善早期预后。

[Abstract] Objective This paper tries to explore the effect of postischemic adaptation on early myocardial protection and prognosis in patients with acute ST elevation myocardial infarction(STEMI). Methods 60 cases of acute STEMI patients who visited the Fourth Hospital of Xinjiang Production and Construction Corps from January 2012 to December 2016 were convenient selected as the object of this study and were divided into experimental group and control group by random number table method, with 30 for each group. Statistical analysis was performed on the reperfusion arrhythmia (RA), postoperative TIMI flow score, no-reflow, acute stent thrombosis, wall motion score and MACE score. Results The incidence of RA in experimental group (10.00%) was significantly lower than the control group (40.00%)(P<0.05); mean MACE score of the control group was significantly higher than the experimental group (P<0.05); the experimental group post infarction angina (13.33%),malignant arrhythmia (16.67%), heart failure (13.33%) single incidence rate of MACE and the control group (respectively 16.67%, 26.67%, 20.00%) had no significant difference(P>0.05). Conclusion Ischemic postconditioning can reduce the STEMI emergency interventional therapy in patients with the incidence of RA, reduce reperfusion injury, reduce infarct size and improve cardiac function in patients with myocardial, has a protective effect on early myocardial, can improve the early prognosis.

心肌持續缺血后,在长时间的再灌注之前,进行一次或数次短暂重复的心肌缺血/再灌注,即缺血后适应,能够提高心肌对缺血的耐受性,减轻缺血再灌注损伤,保护心功能[3]。该文将选择2012年1月—2016年12月就诊于新疆生产建设兵团第四师医院并接受急症PCI治疗的急性急性ST段抬高型心肌梗死(STEMI)患者60例作为该次研究对象,探讨缺血后适应对急性ST段抬高型心肌梗死急症介入治疗患者早期心肌保护及预后影响,为临床提高此类患者疗效及预后提供可靠依据,现报道如下。

1 资料与方法

1.1 一般资料

经随机数字表法将方便选取的就诊于新疆生产建设兵团第四师医院并接受急症PCI治疗的急性STEMI患者60例平均分为实验组、对照组(每组30例)。……
