【摘要】：目的:分析QRS波積分對(duì)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)的預(yù)測(cè)作用。方法:收集在心內(nèi)科住院的STEMI患者80例,無束支傳導(dǎo)阻滯及起搏器置入,隨訪6個(gè)月,記錄其入院時(shí)及出院前標(biāo)準(zhǔn)12導(dǎo)聯(lián)心電圖,用Selvester積分系統(tǒng)方法分為QRS積分≤3組和QRS積分3組,比較兩組臨床特點(diǎn),生化檢查:血BNP,心臟超聲檢查,6個(gè)月內(nèi)患者因心功能不全住院次數(shù)及SCD發(fā)生率,應(yīng)用統(tǒng)計(jì)學(xué)軟件進(jìn)行分析。結(jié)果:QRS積分≤3組共52例,平均年齡(61.4±13.1)歲;QRS積分3組共28例,平均年齡(71.6±11.4)歲,兩組比較差異有統(tǒng)計(jì)學(xué)意義(P0.05);與QRS積分≤3組比較,QRS積分3組患者心率顯著增快[(78.96±15.06)次/min∶(72.0±12.5)次/min,P0.05],非下壁心肌梗死組顯著增多(72.7%∶60.0%,P0.05);QRS積分≤3組在半年年內(nèi)未發(fā)生SCD,QRS積分3組在半年內(nèi)發(fā)生SCD/心力衰竭(心衰)者10例,占該組的35.7%,兩組之間差異有統(tǒng)計(jì)學(xué)意義(P0.05),給予多變量分析后QRS波積分是急性心肌梗死患者心衰/SCD的獨(dú)立危險(xiǎn)因素(OR1.52,95%CI:1.03~2.10,P0.01)。結(jié)論:QRS積分是STEMI患者近期預(yù)后(心功能不全及SCD)獨(dú)立的預(yù)測(cè)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，
