急性心肌梗死时心电图对应导联ST段压低的临床价值分析

Study on clinical significance of acute myocardial infarction patients with or without depression of ST segment

目的探讨急性心肌梗死(AMI)伴或不伴ST段压低(STD)临床意义。方法纳入2009年9月到2012年9月AMI患者65例,其中AMI伴STD患者(STD组)29例,不伴STD患者(NSTD组)36例。分析两组患者冠脉受累支数、心肌损伤标志物水平及体内炎症水平差异。结果 STD组患者更多罹患冠脉多支病变;AMI伴STD患者心肌损伤标志物水平较NSTD患者高;同时,AMI伴STD患者红细胞沉降率(ESR)及C反应蛋白(CRP)水平均较NSTD患者为高。结论 AMI伴STD发生率高,可能提示更严重心肌病变及更强烈炎症反应。

Objective To explore clinical significance in patients with acute myocardial infarction with or without ST segment depression. Methods A total of 65 AMI patients were enrolled in this study. Among them, 29 patients were suffered from AMI with depression of ST seg ment, and 36 were AMI without depression of ST segment. The number of impaired branches of coronary artery in these two groups had been com pared. Levels of cardiac troponin I （cTnI） and creatine kinase MB （ CK MB）, erythrocyte sedimentation rate （ ESR）, and C reactive protein （CRP） were also compared. Results AMI patients with STD were displayed more severe in impairment of coronary artery and more stronger in flammatory reaction with higher serum levels of cTnI, CK MB, ESR and CRP than those of patients without depression of ST segment. Conclu sion AMI patients with STD were more likely to suffer from severe myocardium damage and more attention should be paid to this situation.
