摘　　要：目的：探讨青海高原正常人群冠状动脉形态学改变及左室功能指标的特点。方法选取50例青海高原健康成人行冠状动脉CTA检查，分别测量左冠状动脉主干及各段分支、右冠状动脉主干及分支处的管径，计算左室心功能指标每搏输出量（SV）、射血分数（EF）值和左室收缩末期心室游离壁中段的增厚率，选取平原大连组50例为对照组。结果右冠状动脉近段平均直径平原大连组（3．57±0．68）mm，青海高原组（2．99±0．68）mm，t＝3．510，P＝0．008，差异有统计学意义；余冠状动脉各测量点各组间差异无统计学意义；青海高原组和平原大连组心功能指标间差异无统计学意义。结论青海高原正常人群冠状动脉形态及左心室功能基本等同于平原大连组正常人群。Objective To explore the features of coronary artery morphological changes and left ventricular function indicators of resident population in plateau .Methods 50 plateau healthy adults and 50 plain‐and Dalian‐healthy volunteers completed coronary CTA examination .We measured the pipe diameter of left main coronary atery and right coronary artery and their branches ,respec‐tively .Furthermore ,SV and EF value of left ventricular cardiac function indexes and the wall thickening of free ventricular wall at left ventricular end systolic were measured .Results The average diameter of proximal right coronary of plain‐and Dalian‐healthy volun‐teers thicker than plateau group ,with statistical difference ;Other coronary artery branch did not exhibit any significant between‐group differences ;The two groups did not show significant between‐group differences with heart function indexes .Conclusion The body circulation system have adaptability and compensatory changes of resident population in plateau ,and their coronary artery mor‐phology and left ventricular function are as similar as plain people .
