摘要
目的探讨QRS波时限对肺心病患者短期预后的影响。方法收集两家医院住院诊断慢性肺源性心脏病患者252例,分为QRS波时限正常组(192例,QRS波时限≤120ms)、QRS波时限延长组(60例,QRS波时限>120ms),收集所有患者临床血清生化、心脏超声等结果及临床事件资料,统计分析比较两组临床资料结果及心衰加重、致命性心律失常和心源性死亡等不良心血管事件的发生率。结果QRS波延长组患者心衰加重、致命性心律失常和心源性死亡比例、血浆N末端B型利钠肽原(NT-proBNP)水平、左室舒张末内径(LVEDd)值均较QRS波正常组显著升高(p<0.05)。结论心电图QRS波时限与肺心病患者心衰加重、致命性心律失常和心源性死亡的心血管不良事件相关,临床可将其作为肺心病患者评估短期预后的指标之一。
Objective To investigate the effect of QRS duration on short-term prognosis of patients with pulmonary heart disease.Methods Collected in two hospitals diagnosis of 252 cases of patients with chronic cor pulmonale,the duration of QRS wave normal group(192 cases,duration of QRS wave 120 ms or less),duration of QRS wave group(60 cases,QRS wave duration>120 ms),collect all of the patients serum biochemistry,clinical cardiac ultrasound results and clinical events,such as data,statistical analysis and comparison results of two groups of clinical data and add and fatal arrhythmia and heart failure source sex the incidence of adverse cardiovascular events such as death.Results The increase of heart failure,fatal arrhythmia and cardiogenic death rate,plasma N-terminal B-type natriuretic peptide(NT-probnp)level and left ventricular end-diastolic diameter(LVEDd)in the QRS extended group were significantly higher than those in the QRS normal group(p<0.05).Conclusions QRS duration of electrocardiogram is associated with the aggravation of heart failure,fatal arrhythmia and cardiovascular adverse events of cardiogenic death in patients with pulmonary heart disease,which can be used as one of the clinical indicators to evaluate the short-term prognosis of patients with pulmonary heart disease.
