RESUMO
Objective The epidemiological characteristics of high-altitude pulmonary thromboembolism (PTE) were investigated, and to enhance people's cognitive level of high-altitude PTE. Methods A tatal of 286 patients with PTE admitted to our hospital from May 2017 to October 2019 were selected and divided into study group (n = 143) living at high altitude of 2500 ~ 4500 m and control group (n=143) living at low altitude of 1500~2450m according to altitude.The clinical data, D-D, FIB levels, and laboratory routine examinations were compared between the two groups, and the risk factors were analyzed using univariate analysis and the independent risk factors were analyzed by multivariate logistic regression. Results The levels of D-D and FIB in the control group were significantly increased (P 0.05). Conclusion Those were independent risk factors affecting the incidence of PTE at high altitude，including multivariate logistic regression analysis indicated that red blood cell level, HGB level, DVT, D-D, and FIB. The higher the plasma D-D and FIB levels, the recurrence interval, especially the related diseases of patients at high altitude need regular monitoring.
