目的:探讨进驻海拔4 300m工作人群超声心动图右心动态检查指标变化及其临床意义。方法:利用美国GE-VIVID7型超声诊断仪,对进驻海拔4 300m 247例健康工作人群行超声心动图检查,随访3年,每6个月复查一次,主要参数为肺动脉收缩压、右房压、主肺动脉内径、左肺动脉内径、右肺动脉内径、右室前后径、右室左右径、右房左右径、右室流出道、右室前壁厚度。结果:随着进驻海拔4 300m高海拔环境时间的延长,进驻高海拔环境工作人群的肺动脉收缩压、右房压逐渐升高,右室前后径逐渐增大,左、右肺动脉内径逐渐变小,此变化在高年龄段人群更明显,有统计学差异(P<0.05)。结论:长期进驻高海拔地区工作人群,随着进驻时间的延长,右心系统逐渐出现形态、结构、功能的改变,随着年龄的增长,高原缺氧等因素对人体右心结构及功能的不良影响更趋明显。对高海拔工作人群进行定期超声心动图检查可及时发现高原性心脏病的高危人群,对于临床给予及时预防和干预措施具有重要意义。
Objective: To investigate the changes of echocardiographic right heart dynamic indexes and their clinical significance in working population of 4 300m stationed in the sea. Methods: The American GE-VIVID7 ultrasonic diagnostic apparatus was used to perform echocardiography on 247 healthy working population at an altitude of 4 300m. The patients were followed up for 3 years and reviewed every 6 months. The main parameters were pulmonary artery systolic pressure, right atrial pressure, Diameter of the main pulmonary artery, diameter of the left pulmonary artery, diameter of the right pulmonary artery, anteroposterior diameter of the right ventricle, right and left ventricular diameter of the right ventricle, right and left anteroposterior diameter of the right atrium, right ventricular outflow tract and anterior wall thickness of the right ventricle. Results: The pulmonary artery systolic pressure, right atrial pressure and the right ventricular diameter gradually increased with the increase of the time of entering the high altitude environment of 4 300m above sea level. The diameter of left and right pulmonary artery gradually became smaller, This change in the higher age groups more obvious, statistically significant difference (P <0.05). CONCLUSION: The long-term resident population in high altitude areas, with the extension of residence time, gradually changes in the shape, structure and function of the right ventricular system. As the age increases, hypoxia and other factors on the body’s right ventricular structure and function of the poor The impact is more obvious. Periodic echocardiography in high-altitude working population can detect high-risk population of heart disease in time, which is of great significance for clinical prevention and intervention.
