以超声诊断仪探测心脏结构与功能,发现在有高血压家族史的年轻(17.3±1.3岁)正常血压子女(50名),与无高血压家族史组(50名)相比,前者主动脉根部内径增宽;左房和收缩、舒张末期左室内径、室间隔厚度和左室后壁厚度、左室重量及其指数均增加;反映左室收缩力的喷血分数、平均左室周边纤维缩短速率则减低。其中异常率最高的为左室后壁厚度(62％)、室间隔厚度(42％)、左室重量(40％)、喷血分数(36％)。认为早期左心室肥大可能作为在儿童及少年检出高血压易患者的一项有用指标。
To detect the structure and function of the heart with an ultrasonic diagnostic apparatus, it was found that in the young (17.3 ± 1.3 years) children with normal blood pressure (50) who had a family history of hypertension, compared with the family history without hypertension (50) Left ventricular diameter and left ventricular diameter widened; left atrial and systolic, diastolic left ventricular diameter, ventricular septal thickness and left ventricular posterior wall thickness, left ventricular mass and index were increased; reflect left ventricular ejection fraction spurt, the average left ventricular peripheral fibers Shorten the rate is reduced. Among them, the abnormal rate was the posterior wall thickness (62%), the interventricular septum thickness (42%), the left ventricular weight (40%) and the spurt score (36%). Early LV hypertrophy may be considered as a useful marker of hypertension in children and adolescents.
