ST段时限和ST/QT鉴别诊断肥厚型心肌病与高血压心室肥厚的价值
Value of ST-segment duration and ST/QT in differential diagnosis of hypertrophic cardiomyopathy and hypertensive ventricular hypertrophy
摘要
Abstract
Objective To evaluate the clinical utility of ST-segment duration and ST/QT ratio in differentiating between hypertrophic cardiomyopathy(HCM)and hypertensive ventricular hypertrophy(HVH).Methods A total of 98 subjects were enrolled,including 45 patients without cardiac disease(control group),22 patients with HCM(HCM group),and 31 patients with HVH(HVH group).All participants underwent electrocardiogram(ECG)examinations.The ST-segment duration,QT interval,and ST/QT ratio were compared among the groups,while the diagnostic sensitivity and specificity of ST-segment duration and ST/QT for distinguishing HCM from HVH were assessed.Results Statistically significant differences were observed in ST-segment duration and ST/QT among the three groups(both P＜0.01).Compared with the control group,both HCM and HVH groups exhibited significantly elevated ST-segment duration and ST/QT ratio(both P＜0.01),while no statistically significant difference was found in the QT interval.Diagnostic efficiency evaluation revealed that the sensitivity of ST-segment duration and ST/QT for diagnosing HCM was 77.27％and 86.36％,respectively,with specificity of 86.67％and 77.78％,and AUC values of 0.847(P＜0.01)and 0.859(P＜0.01).For diagnosing HVH,the sensitivity of ST-segment duration and ST/QT was 64.52％and 70.97％,respectively,with specificity of 97.78％and 93.33％,and AUC values of 0.833(P＜0.01)and 0.849(P＜0.01),respectively.Conclusion Both ST-segment duration and ST/QT could serve as diagnostic indicators for HCM and HVH,with high specificity.关键词
