Abstract

Background: Fragmented QRS (fQRS) on the ECG is a straightforward, affordable, and widely accessible indicator of myocardial fibrosis and scarring. Aim: This study aimed to assess the predictive value of (fQRS) in diagnosing myocardial ischemia. It evaluated its incremental prognostic significance in patients having single-photon emission computed tomography (SPECT) for exercise-induced myocardial ischemia. Methods: This observational case-control research was executed on 206 patients who underwent exercise myocardial perfusion SPECT for suspected stable chronic CAD. All patients were subjected to demographic, clinical, and laboratory data, electrocardiography, echocardiography, and SPECT myocardial perfusion imaging. The existence of fQRS was determined based on electrocardiographic criteria. Multivariate logistic regression analysis was applied to predict myocardial ischemia, and the incremental prognostic value of fQRS was determined utilizing hierarchical regression analysis. Results: The patients had a mean age of 53 ±10 years, and more than one-quarter (28.2%) had fQRS. Patients with myocardial ischemia (Group I) had a greater prevalence of fQRS than the control group fQRS (42.3% vs. 23.4%, P = 0.009). In multivariate analysis,

片断 QRS 波群在诊断心肌缺血中的预测价值

背景：心电图上的 QRS 波形片段（fQRS）是心肌纤维化和瘢痕形成的一个直接、经济且广泛使用的指标。目的：本研究旨在评估（fQRS）在诊断心肌缺血方面的预测价值。它还评估了单光子发射计算机断层扫描（SPECT）对运动诱发心肌缺血患者预后的增量意义。研究方法这项观察性病例对照研究的对象是206名因疑似稳定的慢性CAD而接受运动性心肌灌注SPECT检查的患者。所有患者均接受了人口统计学、临床和实验室数据、心电图、超声心动图和 SPECT 心肌灌注成像检查。根据心电图标准确定是否存在fQRS。应用多变量逻辑回归分析预测心肌缺血，并利用层次回归分析确定 fQRS 的增量预后价值。结果患者的平均年龄为 53 ± 10 岁，超过四分之一（28.2%）的患者有 fQRS。心肌缺血患者（I 组）的 fQRS 患病率高于对照组 fQRS 患病率（42.3% 对 23.4%，P = 0.009）。在多变量分析中
