【摘要】：目的研究探讨三维斑点追踪技术于静息条件下在冠心病患者早期诊断中的价值和临床意义。方法对110例可疑冠心病的患者行三维斑点追踪技术(3D-STE)和冠脉造影术(CAG),依据造影结果将患者分为冠心病组和正常组。利用3D-STE技术,得到患者左室心肌各应变的峰值和达峰时间:即纵向、环形、径向、面积应变峰值(LS、CS、RS、AS);纵向、环形、径向、面积应变达峰时间(T-LS、T-CS、T-RS、T-AS)。运用Logistic二元回归分析将各应变峰值和达峰时间指标联合,本研究定义为纵向、环形、径向、面积应变复合指标(LS1、CS1、RS1、AS1)。对上述12项指标采用受试者工作特征曲线(ROC)分析。结果 ROC曲线分析结果示,纵向应变达峰时间(T-LS)和复合指标LS1、CS1、AS1在冠心病的早期诊断中有一定价值,且它们的曲线下面积(AUC)分别为0.667、0.692、0.621、0.672(P0.005)。其中复合指标LS1诊断价值最高,灵敏度及特异度分别为62%、76%。结论 3D-STE在患者静息条件下对早期冠心病的诊断具有一定的价值,其中纵向应变复合指标LS1灵敏度最高。
[Abstract]:Objective to study the value and clinical significance of three-dimensional speckle tracing technique in early diagnosis of coronary heart disease (CHD). Methods 110 patients with suspected coronary heart disease were divided into coronary heart disease group and normal group according to the results of angiography. The patients were divided into three dimensional speckle tracing technique (3D-STE) and coronary angiography (CAGG). By using 3D-STE technique, the peak and peak time of each strain of left ventricular myocardium were obtained: longitudinal, annular, radial, area strain peak and longitudinal, annular, radial, area strain peak time (T-LSN T-CSN T-RSN T-ASA), longitudinal, circular, radial, area strain peak time. The Logistic regression analysis was used to combine the peak strain and the peak time index. In this study, the composite index of longitudinal, annular, radial and area strain was defined as LS1 / CS1 / RS1 / AS1. The above 12 indexes were analyzed by the operating characteristic curve (ROC). Results the results of ROC curve analysis showed that the longitudinal strain peak time (T-LS1) and the composite index LS1 / CS1 AS1 were valuable in the early diagnosis of coronary heart disease, and the area under the curve was 0. 667 7 ~ 0. 692 ~ 0. 621 ~ 0. 672 卤0. 672% (P 0. 005), respectively. The diagnostic value of LS1 was the highest, the sensitivity and specificity were 622% and 76%, respectively. Conclusion 3D-STE has a certain value in the diagnosis of early coronary heart disease under resting condition, in which longitudinal strain compound index LS1 has the highest sensitivity.
