摘　　要：目的:探讨分析超声心动图对于高原性肺动脉高压的诊断价值。方法:选取74例高原性肺动脉高压患者纳入观察组;以同期60名健康体检者纳入对照组。所有入组者均进行超声心动图检查,观测心脏和大血管结构改变,测定收缩期肺动脉压(SPAP)等指标。结果:观察组74例患者肺动脉收缩压最小值34.0 mm Hg,最大值62.0 mm Hg,平均(43.8±9.2)mm Hg。高原性肺动脉高压患者典型的心脏超声表现包括右心和肺动脉改变,三尖瓣、肺动脉瓣返流及右室功能降低,观察组患者各项超声指标与对照组比较差异有统计学意义(t=9.518,t=11.308,t=7.945,t=10.623,t=4.582,t=9.683,t=4.371,t=8.472;P<0.05);而观察组患者左心功能正常,左室射血分数(LVEF)和Tei指数均正常,与对照组比较差异无统计学意义(t=0.289,t=1.052;P>0.05)。结论:超声心动图在高原性肺动脉高压的诊断中具有重要的临床价值,是该疾病首选的重要检查手段。Objective To evaluate the diagnostic value of echocardiography used in highaltitude pulmonary hypertension. Methods：74 cases of patients with high altitude pulmonaryhypertension into the observation group, to 60 healthy subjects were included in the controlgroup. All patients underwent echocardiography, cardiac and macrovascular structural changeswere observed to determine pulmonary artery pressure （SPAP）, etc. Results： Minimum SPAP of 74 patients is 34.0mmHg, the maximum value of 62.0 mmHg, mean 43.8±9.2mmHg. The typical echocardiography findings of highaltitude pulmonary hypertension include right heart and pulmonary changes, tricuspid, pulmonary valve regurgitation,right ventricular function decreased, There were significant differences between the observation group and the controlgroup （t=9.518, t=11.308, t=7.945, t=10.623, t=4.582, t=9.683, t=4.371, t=8.472; P〉0.05）. The left ventricularejection fraction （LVEF） and Tei index were normal in the observation group, and there was no significant differencecompared with the control group（t=0.289, t=1.052; P〉0.05）. Conclusion： Echocardiography is the preferred highaltitude pulmonary hypertension and an important means of examination, has important clinical value in the diagnosisof the disease.
