目的探究高原地区世居居民与常住居民的心脏结构和功能的差异性。方法选择2022年6月—2023年8月在西藏林芝市人民医院体检的200例世居居民与常住居民作为研究对象,将世居居民和常住居民按照性别分为男女亚组,按照年龄段分为18~31岁、31~40、41~50岁亚组。比较各亚组心脏结构参数、左心功能参数、多普勒超声检测参数差异。结果与高原常住居民男性和女性比较,世居居民男性和女性的左房内径、右房内径、右室内径、肺动脉内径、升主动脉内径、主动脉根径、室间隔厚度、左室后壁厚度、左室舒张末内径、左室收缩末内径、左室射血分数、二尖瓣 A 峰流速指标比较差异均无统计学意义（P>0.05）;而主动脉瓣口流速、肺动脉瓣口流速、二尖瓣 E 峰流速增加,两组间比较差异具有统计学意义（P<0.05）。18~31岁、31~40、41~50岁组世居居民和常住居民左房内径、右房内径、右室内径、肺动脉内径、升主动脉内径、主动脉根径、室间隔厚度、左室后壁厚度、左室舒张末内径、左室收缩末内径、左室射血分数、二尖瓣 A 峰流速指标等指标比较差异均无统计学意义（P>0.05）,但世居居民主动脉瓣口流速、肺动脉瓣口流速、二尖瓣 E 峰流速均高于常住居民,差异具有统计学意义（P<0.05）。结论高原地区世居居民和常住居民心脏结构参数和左心功能参数无明显差异。但世居居民主动脉瓣口流速、肺动脉瓣口流速、二尖瓣 E 峰流速均高于常住居民。

Objective To explore the ethnic differences in heart structure and function between aborigines and long term residents in the plateau area. Methods A total of 200 aborigines and long term residents who underwent physical examination in our hospital from June 2022 to August 2023 were selected as the study subjects,and the aborigines and long term residents were divided into male and female subgroups,and subgroups aged 18-30 years,31-40 years and 41-50 years．The differences of cardiac structure parameters,left ventricular function parameters and Doppler parameters were compared among subgroups. Results The left atrial diameter,right atrial diameter,right ventricular diameter,pulmonary artery diameter,ascending aorta diameter,aortic root diameter,interventricular septal thickness,left ventricular posterior wall thickness,left ventricular end-diastolic diameter,left ventricular end-systolic diameter,left ventricular ejection fraction mitral valve A peak velocity were compared between Aborigines and plateau Long Term Residents,which were no significant difference（P>0.05）．However,the velocity of aortic valve orifice,pulmonary valve orifice and mitral valve E peak velocity increased,and the differences were statistically significant（P<0.05）．There were no significant differences in left atrial diameter,right atrial diameter,right ventricular diameter,pulmonary artery diameter,ascending aorta diameter,aortic root diameter,interventricular septal thickness,posterior left ventricular wall thickness,left ventricular end-diastolic diameter,left ventricular end-systolic diameter,left ventricular ejection fraction,left ventricular diameter,left ventricular diameter,and left ventricular ejection fraction mitral valve A peak velocity indexes in aborigines and long term residents between among aged 18-30 years,31-40 years,41-50 years（P>0.05）,but the differences of aortic valve orifice velocity,pulmonary valve orifice velocity and mitral valve E peak velocity were statistically significant（P<0.05）. Conclusions There were no significant difference in cardiac structure parameters and left heart function parameters between aborigines and long term residents in plateau area．However,the aortic orifice velocity,pulmonary orifice velocity and mitral E-peak velocity of aborigines were higher than those of long term residents．
