【摘要】：目的:分析QRS波积分对ST段抬高型急性心肌梗死(STEMI)患者近期心功能不全及心源性猝死(SCD)的预测作用。方法:收集在心内科住院的STEMI患者80例,无束支传导阻滞及起搏器置入,随访6个月,记录其入院时及出院前标准12导联心电图,用Selvester积分系统方法分为QRS积分≤3组和QRS积分3组,比较两组临床特点,生化检查:血BNP,心脏超声检查,6个月内患者因心功能不全住院次数及SCD发生率,应用统计学软件进行分析。结果:QRS积分≤3组共52例,平均年龄(61.4±13.1)岁;QRS积分3组共28例,平均年龄(71.6±11.4)岁,两组比较差异有统计学意义(P0.05);与QRS积分≤3组比较,QRS积分3组患者心率显著增快[(78.96±15.06)次/min∶(72.0±12.5)次/min,P0.05],非下壁心肌梗死组显著增多(72.7%∶60.0%,P0.05);QRS积分≤3组在半年年内未发生SCD,QRS积分3组在半年内发生SCD/心力衰竭(心衰)者10例,占该组的35.7%,两组之间差异有统计学意义(P0.05),给予多变量分析后QRS波积分是急性心肌梗死患者心衰/SCD的独立危险因素(OR1.52,95%CI:1.03~2.10,P0.01)。结论:QRS积分是STEMI患者近期预后(心功能不全及SCD)独立的预测因子。
[Abstract]:Objective: to analyze the predictive effect of QRS wave integral on short term cardiac insufficiency and sudden cardiac death (SCD) in patients with St segment elevation acute myocardial infarction (STEMI). Methods: a total of 80 patients with STEMI in cardiology department without bundle branch block or pacemaker implantation were collected and followed up for 6 months to record the standard 12-lead electrocardiogram at admission and before discharge. Selvester integral system was used to divide the patients into three groups: QRS integral 鈮，
