【摘要】：目的探討急性心肌梗死(AMI)患者心電圖碎裂QRS(fQRS)波與冠脈病變程度及心臟事件的相關性。方法根據(jù)AMI患者心電圖有無fQRS波,分為fQRS組和nfQRS組。記錄病史資料、檢驗指標、心電圖、冠脈造影及隨訪結(jié)果,計算SYNTAX評分,評估冠脈病變情況,記錄心臟事件的發(fā)生情況。結(jié)果與nfQRS組相比,fQRS組肌鈣蛋白(c Tn)I、肌酸激酶同工酶(CK-MB)、肌酐(Cr)、尿酸(UA)、腦鈉肽(BNP)、D-二聚體(D-D)水平顯著升高,左室舒張末期內(nèi)徑(LVEDD)顯著加大,左室射血分數(shù)(LVEF)顯著降低(均P0.05)。fQRS組多支病變、SYNTAX評分顯著高于nfQRS組(均P0.01),單支病變顯著低于nfQRS組(均P0.01)。隨訪期間,fQRS組室性心動過速/室顫、心源性休克、心源性死亡、嚴重心力衰竭、再發(fā)心肌梗死、再次血運重建發(fā)生率均顯著高于nfQRS組(P0.05)。與fQRS導聯(lián)數(shù)3組患者相比較,fQRS導聯(lián)數(shù)≥3組患者室性心動過速/室顫、心源性休克、心源性死亡、嚴重心力衰竭的發(fā)生率均顯著升高(P0.05)。結(jié)論 fQRS可作為預測冠脈病變程度及心臟不良事件的指標,提高AMI高危患者的預警作用。
[Abstract]:Objective to investigate the correlation between electrocardiogram (ECG) fragmentation of QRSs f QRS and the severity of coronary artery disease and cardiac events in patients with acute myocardial infarction (AMI). Methods the patients with AMI were divided into fQRS group and nfQRS group according to whether there were fQRS waves in ECG. Record the history, test index, electrocardiogram, coronary angiography and follow-up results, calculate the SYNTAX score, assess the coronary lesions, record the occurrence of cardiac events. Results compared with nfQRS group, the levels of troponin I, creatine kinase isoenzyme (CK-MBN), creatinine (Cr), uric acid (UAA), brain natriuretic peptide (BNP), D-dimer (D-D) and left ventricular end-diastolic diameter (LVEDDD) were significantly increased in FQRS group. The left ventricular ejection fraction (LVEF) was significantly lower in P0.05).fQRS group than in nfQRS group (P 0.01), and that in single vessel lesion group was significantly lower than that in nfQRS group (P 0.01). During the follow-up period, the incidence of ventricular tachycardia / ventricular fibrillation, cardiogenic shock, cardiogenic death, severe heart failure, recurrent myocardial infarction and re-revascularization in fQRS group was significantly higher than that in nfQRS group (P 0.05). The incidence of ventricular tachycardia / ventricular fibrillation, cardiogenic shock, cardiogenic death and severe heart failure in patients with fQRS leads 鈮，
