摘　　要：本文观察了三个不同海拔高度（６２０ｍ、２２６０ｍ、３３００ｍ）肺心病Ｘ线形态学有关指标的改变，可望为分析肺心病的发病机理，提高防治水平提供一定的资料依据。方法：根据全国第二批肺心病专业会议（１９７７年）修订的诊断标准确立诊断。肺心病患者１５６例，男性，平均年龄６３岁。本文Ｘ线胸片皆系同类Ｘ线机拍摄，常规测量心血管经线。观察肺纹理改变情况。结果：右肺下动脉横径、肺动脉段突度、降支与气管横径比值三项参数有随海拔高度增高而依次递增，差异显著（Ｐ＜０．０１）。三个不同海拔高度肺心病的肺纹理Ｘ线特征表现分类（模糊型、网状纤维型、瘀血型）初步揭示，随海拔高度增加肺纹理瘀血型改变人数增加。结论：本文揭示，肺纹理类型改变对评估肺心病的发作程度和监督指导疗效都有着较高的临床实用价值。o studythe effects of high altitude on corpulmonale.156 male cases with cor pulmonale at620m,2260m and 3300m altitudes underwent chest X-rav exam.The X-ray films were anal-ysed and some parameters were measured.The diameter of right inferior pulmonary artery,themain pulmonary artery segment.and the ratio of right inferior pumonary artery and trachea in-creased with the altitude going up.The difference was stignificant(P<0.01).According to thefeatures of lung marking.the patients could be divided into three types,indistinct,wed-like fi- brous and congesive types.The congesive type increased with altitude going up.The change oflung marking type showed Clinical significance toestimate the degree of cor pulmonale,
