                关系。方法:研究对象为 2021 年在江苏省丹阳市车站社区招募的受试者。使用 GE Vivid E90 超声仪测量分析 cIMT;二维斑
                点追踪技术采集左心室整体纵向应变(left ventricular global longitudinal strain,LVGLS)作为评估亚临床收缩功能的指标,二
                尖瓣口血流频谱和组织多普勒成像采集 e’和 E/e’比值作为评估亚临床舒张功能的指标。结果:研究共计纳入 561 例,年龄
               (58.2±11.7)岁,其中女339例(60.4%)。首先使用三分位法将cIMT作为分类变量分析,在单因素分析中,除了左心室射血分数
                外,LVGLS,E/A和e’均随着cIMT三分位数从低到高下降,而E/e’比值随着cIMT三分位数从低到高增加(均Ptrend ≤ 0.002)。然
                而,进一步进行多因素校正分析后,只有LVGLS仍随着cIMT三分位数从低到高下降(P < 0.05)。进一步将cIMT自然对数转
                换后进行连续变量分析,结果与分类变量分析结果类似,仅有LVGLS与cIMT显著负相关(r=-0.087,P=0.041);并且在回归分
                析中也发现了类似的结果(β=-1.12,P=0.041)。结论:在江苏丹阳社区人群中,cIMT增厚与GLS减低独立相关。

               [Abstract] Objective: To explore the relationship between carotid intima⁃media thickness(cIMT)and subclinical left ventricular
                function in population of Danyang community. Methods: The study subjects were recruited in 2021 from the Station Community of
                Danyang City,Jiangsu Province. cIMT was measured and analyzed by GE Vivid E90 ultrasound instrument. Two⁃dimensional(2D)
                speckle tracking technology was used to collect left ventricular global longitudinal strain(LVGLS)of the left ventricle as an indicator
                for assessing subclinical systolic function. The e’and E/e’ratio were obtained from mitral valve blood flow spectra and tissue Doppler
                imaging,serving as indicators for evaluating subclinical diastolic function. Results: A total of 561 participants with an average age of
               (58.2 ± 11.7)years were enrolled,among whom 339(60.4% )were females. Using tertiles of cIMT as a categorical variable,in
                univariate analysis,LVGLS,E/A ratio,and e’decreased as cIMT tertiles increased,while the E/e’ratio increased(all Ptrend ≤ 0.002),
                except for left ventricular ejection fraction. However,after further multivariate adjustment,only LVGLS continued to decrease with
                increasing cIMT tertiles(P < 0.05). Continuous variable analysis after natural logarithm transformation of cIMT yielded results similar
                to categorical variable analysis,with only LVGLS showing a significant negative correlation with cIMT(r=- 0.087,P=0.041),and
