| 目的 探讨三维超声斑点追踪技术(3D-STE)对老年冠心病合并高血压患者左心功能的评估价值。方法 选取2021年3月~2022年3月在湖北医药学院附属国药东风总医院-湖北省高血压临床医学研究中心收治的60例老年冠心病合并高血压患者为合并CHD组,随机选取同期60例高血压患者为单纯EH组。两组均进行3D-STE检测左心功能。比较两组左房容积参数、射血分数、左心室整体应变峰值、左房峰值纵向应变(PALS)、左房收缩峰值应变(PACS)、颈动脉硬化的内膜中层厚度(IMT)、狭窄程度和颈动脉斑块(Crouse)积分。采用多因素Logistic 回归分析老年CHD合并EH患者左心功能改变的独立危险因素。结果 经三维超声心动图检测,合并CHD组左房容积参数和LAAEF均高于单纯EH组,LATEF、LVEF均低于单纯EH组(P<0.05)。经3D-STE检测,合并CHD组和单纯EH组的左心室整体应变峰值(左室整体面积、圆周、径向、纵向收缩期峰值应变)差异有统计学意义(P<0.05)。经3D-STE检测,合并CHD组整体、四腔、两腔的PALS值、PACS值均低于单纯EH组(P<0.05)。经3D-STE检测,合并CHD组和单纯EH组的IMT厚度、狭窄程度和Crouse积分差异有统计学意义(P<0.05)。Logistic 回归分析结果显示,LAAEF、GAS、IMT厚度、狭窄程度、Crouse积分均为老年CHD合并EH患者左心功能改变的危险因素(P<0.05)。结论 3D-STE可较好评价左室局部及整体的收缩功能,对诊断老年冠心病合并高血压患者左心功能具有一定的评估价值。 |

| Abstract: |
| Objective To explore the evaluation value of three-dimensional ultrasonic speckle tracking echocardiography (3D-STE) for left ventricular function in elderly patients with coronary heart disease (CHD) and hypertension (EH). Methods A total of 60 elderly patients with CHD and EH admitted to Sinopharm Dongfeng General Hospital Affiliated to Hubei Medical College-Hubei Provincial Clinical Medical Research Center for Hypertension were enrolled as combined CHD group between March 2021 and March 2022, while 60 patients only with EH during the same period were randomly enrolled as simple EH group. All underwent 3D-STE to detect left ventricular function. The left atrial volume parameters, ejection fraction, global strain peak of left ventricle, carotid intima-media thickness (IMT), peak atrial longitudinal strain (PALS), peak atrial contraction strain (PACS), stenosis degree and score of carotid plaques (Crouse) were compared between the two groups. The independent risk factors of left ventricular function changes in elderly patients with CHD and EH was analyzed by multivariate Logistic regression analysis. Results 3D-STE showed that left atrial volume parameters and LAAEF in combined CHD group were higher than those in simple EH group, while LATEF and LVEF were lower than those in simple EH group (P<0.05). 3D-STE showed that there were significant differences in global strain peak of left ventricle (left ventricular overall area, circumference, radial and longitudinal peak systolic strain) between the two groups (P<0.05). 3D-STE showed that PALS and PACS of entirety, four-chamber and two-chamber in combined CHD group were lower than those in simple EH group (P<0.05). 3D-STE showed that there were significant differences in IMT, stenosis degree and Crouse score between the two groups (P<0.05). The results of Logistic regression analysis showed that LAAEF, GAS, IMT, stenosis degree and Crouse score were all risk factors of left ventricular function changes in elderly patients with CHD and EH (P<0.05). Conclusion 3D-STE can better evaluate local and global systolic function of left ventricle, which has certain evaluation value for left ventricular function in elderly patients with coronary heart disease and hypertension. |
