急性ST段抬高心肌梗死介入治疗后体温升高对左室功能的影响

摘要

目的：探讨急性心肌梗死（AMI）后体温升高对左室功能的影响。方法：选择2011年1月至2013年3月因急性ST段抬高心肌梗死行急诊PCI治疗成功的患者176例，测量腋下体温，每6 h 1次，连续测量1周。按体温峰值分为体温正常组（A组，体温＜37.3℃）和体温升高组（B组体温≥37.3℃），比较两组间临床特征、心肌酶（肌酸激酶同工酶CK-MB）、炎症指标及心功能的差异。结果：A组心肌酶、hs-CRP水平、白细胞计数明显较高（P＜0.05），而左室射血分数低于B组（P＜0.05）。结论：AMI再灌注后发热仍然与坏死面积大小及心功能受损有关，提示预后不良。%[ABSTRACT]Objective:To investigate the effect of elevated temperature on left ventricular function in patients with acute myocardial infarction(AMI). Methods:176 patients with acute ST segment elevation myocardial infarction treated by PCI were selected from January 2011 to March 2013, 1/6h, 1 week, measured under the armpit temperature. According to the temperature peak points with elevated temperature normal group (group A, temperature<37.3℃) and body temperature group (group B temperature≥37.3℃), the differences were compared between the two groups clinical features, myocardial enzyme (creatine kinase isoenzyme,CK-MB), markers of inlfammation and cardiac function. Results:The levels of myocardial enzymes, hs-CRP and P<0.05 were signiifcantly higher in A group than in B group (P<0.05). Conclusion:Fever is still associated with the size of necrotic area and impaired cardiac function in AMI after reperfusion, suggesting a poor prognosis.
