【摘要】:目的:探討行急診PCI治療的急性前壁心肌梗死患者入院心電圖aVR導(dǎo)聯(lián)T波方向與住院期間轉(zhuǎn)歸的關(guān)系。 方法:隨機(jī)選取我院2011年1月至2012年12月行急診PCI術(shù)的急性前壁心肌梗死患者75人(平均年齡59.5±11.6歲,男性59人)進(jìn)行回顧性分析。入選標(biāo)準(zhǔn):①癥狀發(fā)生12小時內(nèi)(典型的胸痛持續(xù)時間30分鐘,含服硝酸甘油無效)行急診PCI術(shù);②急性前壁心肌梗死心電圖特征或動態(tài)改變,ST段測量為J點后60ms,至少2個連續(xù)心電圖導(dǎo)聯(lián)ST段改變幅度≥2mm;③血清肌鈣蛋白I(cTnI)的動態(tài)演變。排除標(biāo)準(zhǔn):①無血管成形術(shù)指征及冠脈搭橋手術(shù)史;②嚴(yán)重瓣膜疾病、心室肥厚、其他部位心室壁心肌梗死、嚴(yán)重的電解質(zhì)紊亂、左或右束支傳導(dǎo)阻滯、室內(nèi)傳導(dǎo)阻滯、起搏心律、預(yù)激綜合征、心房撲動、心房纖顫致ST段不能準(zhǔn)確測量者。根據(jù)入院心電圖aVR導(dǎo)聯(lián)T波方向?qū)⒒颊叻譃門波直立組(≥0mm,N=24,A組)和T波倒置組(0mm,N=51,B組)。詳細(xì)記錄兩組患者的一般臨床資料、肌酸激酶同工酶、肌鈣蛋白I、aVR導(dǎo)聯(lián)ST段水平、左心室射血分?jǐn)?shù)、冠脈造影結(jié)果、非死亡患者住院時間和住院期間嚴(yán)重心血管事件(心肌再梗死、惡性心律失常、嚴(yán)重心力衰竭、心源性休克及心源性死亡)等資料。應(yīng)用SPSS21.0統(tǒng)計軟件進(jìn)行統(tǒng)計分析,以p0.05為差異具有統(tǒng)計學(xué)意義。 結(jié)果:行急診PCI術(shù)的急性前壁心肌梗死患者中,aVR導(dǎo)聯(lián)T波直立組左室射血分?jǐn)?shù)更低(A組45.04%±16.247%,B組:51.59%±10.566%,p0.05),排除死亡患者后A組的住院時間更長(A組9.68±2.709天,B組7.55±2.424天,p0.05)。多支病變患者共38例(A組17例、B組21例),A組多支病變患者比例明顯高于B組(A組70.8%、B組41.2%,p0.05),敏感性、特異性和準(zhǔn)確率分為44.7%、81.8%和62.6%。住院期間發(fā)生嚴(yán)重心血管事件的患者共38例(A組11例、B組5例,p0.05),A組較B組患者住院期間嚴(yán)重心血管事件發(fā)生率更高(A組45.8%、B組9.8%,p=0.000),敏感性、特異性和準(zhǔn)確率分為68.8%、78.0%和76.0%。住院期間死亡在A、B兩組間差異無統(tǒng)計學(xué)意義(p0.05)。經(jīng)過多因素分析后,aVR導(dǎo)聯(lián)T波直立(OR:6.710,95%CI:1.713-26.282,p0.05)是住院期間嚴(yán)重心血管事件發(fā)生的獨(dú)立危險因素。 結(jié)論: 1、行急診PCI術(shù)的急性前壁心肌梗死患者中,入院心電圖aVR導(dǎo)聯(lián)T波直立者左室射血分?jǐn)?shù)更低、非死亡患者住院時間更長。 2、行急診PCI術(shù)的急性前壁心肌梗死患者中,入院心電圖aVR導(dǎo)聯(lián)T波直立者冠狀動脈多支病變、住院期間嚴(yán)重心血管事件的發(fā)生率更高,,T波直立是患者住院期間嚴(yán)重心血管事件的獨(dú)立危險因素。 3、入院心電圖aVR導(dǎo)聯(lián)T波直立對行急診PCI術(shù)的急性前壁心肌梗死患者住院期間轉(zhuǎn)歸的預(yù)測評估具有一定臨床價值。

Standard 1: 1 symptom occurred within 12 hours (typical chest pain duration 30 minutes, including no effect of nitroglycerin) performed emergency PCI; 2electrocardiogram (ECG) characteristics or dynamic changes of St segment in acute anterior wall myocardial infarction (AMI) were measured to be 60 Ms after J point, and at least 2 ST segments of continuous electrocardiogram were more than 2 mm ~ (-3). The dynamic evolution of serum troponin I (cTnI) was found in patients with acute anterior wall myocardial infarction. No indication of angioplasty and coronary bypass graft history of severe valvular disease, ventricular hypertrophy, myocardial infarction in other parts of the ventricle, severe electrolyte disturbance, left or right bundle branch block, ventricular block, Pacing rhythm, preexcitation syndrome, atrial flutter, atrial fibrillation caused by ST segment can not be accurately measured.
