| 目的 应用彩色多普勒超声检查观察超重对心脏结构、功能及颈动脉内-中膜厚度(IMT)的影响。方法 根据体质量指数(BMI)将100名体检者分为正常对照组(BMI<25 kg/m2,47名)和超重组(BMI≥25 kg/m2,53名)。对两组均行彩色多普勒超声心动图及颈动脉超声检查,分析超重对心脏结构、功能及颈动脉IMT的影响。结果 与正常对照组相比,超重组左心室舒张末期内径(LVDD)、左心室舒张末期室间隔厚度(IVST)、左心室后壁舒张末期厚度(LVPWT)、左心室质量(LVM)、左心室质量指数(LVMI)、二尖瓣舒张晚期峰值血流速度(A峰)、颈动脉IMT增高,二尖瓣舒张早期峰值血流速度(E峰)和E／A降低,差异均有统计学意义(P均<0.05)。BMI与LVDD、IVST、LVPWT、LVM、LVMI、A峰、颈动脉IMT均呈显著正相关(P均<0.05),与E/A、E峰均呈负相关(P均<0.01)。结论 超声检查发现无任何临床症状的超重人群可发生左心室增大、舒张功能减退以及颈动脉IMT。 |

| Objective To investigate the influence of overweight on cardiovascular system with color Doppler ultrasonography. Methods Totally 100 people accepted health examination were included and classified into 2 groups according to body mass index (BMI): Overweight group (BMI≥25 kg/m2, n=53) and control group (BMI<25 kg/m2, n=47), both underwent color Doppler ultrasonography. The heart structure, heart function and carotid artery intima-media thickness(IMT) of them were compared. Results Compared with control group, left ventricular diameter in end diastole (LVDD), interventricular septum thickness (IVST), left ventricular posterior wall thickness (LVPWT), left ventricular mass (LVM), left ventricular mass index (LVMI), peak A velocity (A) and IMT of overweight group all increased, peak E velocity (E) and E/A both decreased (all P＜0.05). In all of 100 people, LVDD, IVST, LVPWT, LVM, LVMI, A and IMT were all positively correlated with BMI, E/A and E were both negatively correlated with BMI. Conclusion Ultrasound examination showed that injury of left ventricle structure, relaxing function and intima-media thickness can occur in overweight without clinical symptoms. |
