摘　　要：目的以超声心动图测量为手段,就西藏地区健康人群与北京地区汉族健康人群进行比较,研究高原环境、不同民族心脏形态、功能的差异。方法以西藏地区常住人口为总体,采用分层4阶段随机抽样方法抽取调查对象,筛选高原藏汉健康人群,与平原汉族健康人群心脏测量数据进行比较。结果通过高原藏族健康人群与平原汉族健康人群匹配后心脏功能比较,发现高原藏族右心室测量指标要大于平原汉族人群。而大血管测量指标主动脉窦内径、升主动脉内径、主肺动脉内径,部分左心测量指标包括左房左右径、前后径、左室舒张末内径、左室射血分数方面,高原藏族要小于平原汉族;主肺动脉、升主动脉、三尖瓣环收缩期位移汉族健康人群高于藏族健康人群,其余指标两组之间差异无统计学意义(P>0.05)。结论高原环境与右心室扩大,左心室受抑制有关;民族因素对高原适应人群心脏影响有限。Objective The goal of the manuscript was to present the impact of difference region and ethnicity on echocardiographic measurements. Methods A representative sample of residents in Tibet was recruited using a multistage cluster random sampling method. Healthy Tibetans and healthy Han highlanders were drawn from the sample. We explore discrepancy of cardiac chamber diameters and function in healthy Han lowlanders versus healthy Tibetans,and healthy Han highlanders versus Tibetans. Results Healthy Tibetans have higher measurements of right ventricle,less diameters of aortic artery,pulmonary artery,left atrium and left ventricle in diastolic end,and lower left ventricular ejection fraction than healthy Han lowlanders after matching.Whereas,healthy Tibetans had similar cardiac chamber diameters and function with healthy Han highlanders,except main pulmonary artery,ascending aortic artery and tricuspid annular plane systolic excursion. Conclusion There is apparent difference in cardiac structure between Han lowlanders and Tibetans,little difference between healthy Han highlanders and Tibetans.
