高原红细胞增多症是常见的慢性高原病,尽管本症临床上以血液学变化为特征,但心血管和呼吸方面的改变也常较突出,并可能为本病的重要病理生理环节。自1980～1984年,我们对在海拔3,681～4,179米地区确诊的34例高原红细胞增多症病人进行了系统的心血管变化的观测及血液气体分析,并与当地高原健康人相对照,以探讨与发病机理的联系。 High altitude polycythemia is a common chronic disease, although the disease is clinically characterized by hematological changes, but cardiovascular and respiratory changes are often more prominent, and may be an important pathophysiology of the disease. From 1980 to 1984, we conducted systematic cardiovascular changes and blood gas analysis of 34 patients with high altitude polycythemia diagnosed in the area of ​​3,681-4,179 meters above sea level, and compared them with healthy people in the local plateau to explore the relationship between Pathogenesis of the link.
