中文摘要: 目的 分析冠心病患者心电异常活动程度及超声测量参数与其病变程度关联性及预后评估价值。方法 回顾性选取2018年1月至2019年1月收治的老年冠心病患者109例,均接受心电图及超声检查。统计不同病变程度冠心病患者超声［左房内径(LAD)、左室舒张末期容积(LVDd)、E峰/A峰比值(E/A)］及心电图指标(QTc间期、QRS时限值),并给予对应治疗,比较不同疗效及不同预后老年冠心病患者上述指标水平,统计分析心电图指标及超声指标与病变程度的关联性。结果 (1)不同病变程度:中度患者LAD、LVDd及QTc间期、QRS时限值高于轻度患者,E/A低于轻度患者(P<0.05);重度患者LAD、LVDd及QTc间期、QRS时限值高于中度患者,E/A低于中度患者(P<0.05);(2)不同预后:预后良好者LAD、LVDd及QTc间期、QRS时限值低于预后不佳者,E/A高于预后不佳者(P<0.01);(3)关联性:LAD、LVDd及QTc间期、QRS时限值与病变程度呈正相关关系,E/A与病变程度呈负相关关系(P<0.01)。结论 LAD、LVDd及QTc间期、QRS时限值与冠心病老年患者病变程度呈正相关,E/A与冠心病老年患者病变程度呈负相关,临床通过检查心电异常活动程度及超声测量参数,可为评估病变程度、对症治疗、判定预后效果提供循证数据支持。
Abstract:ObjectiveTo analyze the associations of abnormal electrocardiographic (ECG) signals and ultrasonic parameters with the degree of pathological changes in patients with coronary heart disease (CHD) and their evaluation on prognosis.MethodsA total of 109 elderly patients with CHD from January 2018 to January 2019 were selected retrospectively,and all of them were examined by resting ECG and ultrasound.The ultrasonic parameters,including left atrial diameter (LAD),left ventricular diastolic dysfunction (LVDd),the ratio of peak E-wave velocity to peak A (E/A ratio) and ECG parameters,including the rate-corrected QT (QTc) interval,QRS time limit were observed.The corresponding treatments were given in CHD patients.The correlations of above indexes with pathological changes and different prognosis of the patients were studied.Results(1) LAD,LVDd,QTc interval and QRS time limit increased significantly,and E/A ratio decreased significantly with the increase of disease severity of patients (P<0.05).（2）LAD,LVDd,QTc interval and QRS time limit in patients with good prognosis were lower than those with poor prognosis,and E/A ratio was higher than that of patients with poor prognosis (P＜0.01）.(3）LAD,LVDd,QTc interval and QRS time limit were positively correlated with the disease severity,while E/A ratio was negatively correlated with the disease severity (P<0.01).ConclusionsAbnormal ECG signals and ultrasonic parameters can provide evidence-based data support for the evaluation of pathological changes,symptomatic treatment and prognosis in the elderly patients with CHD.
