摘要
目的分析变异型心绞痛(VAP)患者心电图QT间期(QTc)改变对室性心律失常发生的预测价值。方法采取回顾性研究,收集2019年2月至2021年2月期间我院收治的120例VAP患者临床资料。统计VAP患者治疗期间室性心律失常发生情况,将发生室性心律失常患者纳入发生组,将未发生患者纳入未发生组。记录两组患者心电图参数[QTc、QT间期离散度(QTd)、ST段抬高度(STE)],并分析VAP患者QTc改变对室性心律失常发生的预测价值。结果变异型心绞痛患者共120例,其中发生31例室性心律失常,发生率25.83%(31/120);发生组QTc、QTd长于未发生组,STE低于未发生组,差异有统计学意义(p<0.05);绘制ROC曲线结果显示,QTc、QTd、STE及联合检测AUC均>0.7,其中联合检测诊断价值最高。结论变异型心绞痛患者QTc改变能够有效预测室性心律失常的发生,临床可通过VAP患者QTc水平变化,评估室性心律失常发生风险。
Objective To analyze the predictive value of QT interval(QTc) changes in patients with variant angina pectoris(VAP) for ventricular arrhythmia. Methods A retrospective study was conducted, the clinical data of120 VAP patients treated in our hospital from February 2019 to February 2021 were collected. The occurrence of ventricular arrhythmia in VAP patients during treatment was counted, patients with ventricular arrhythmia were included in the occurrence group, and patients without ventricular arrhythmia were included in the non occurrence group. Electrocardiogram parameters [QTc, QT interval dispersion(QTd), ST segment elevation(STE)] of patients in the two groups were recorded, the predictive value of electrocardiogram QTc changes in patients with AVP for ventricular arrhythmia was analyzed. Results Among 120 patients with VAP, 31 patients had ventricular arrhythmia,the incidence was 25.83%(31/120);QTc and QTd in the occurrence group were longer than those in the non-occurrence group, while STE in the occurrence group was lower than that in the non-occurrence group, the differences were statistically significant(p<0.05);the ROC curve was drawn, and the results showed that the AUC of QTc, QTd, STE and combined detection were all >0.7, of which the combined detection had the highest diagnostic value. Conclusions The change of QTc in VAP patients can effectively predict the occurrence of ventricular arrhythmia, the risk of ventricular arrhythmia can be evaluated by the change of QTc level in VAP patients.
