[Vicissitudes of proportion and mortality of patients with pulmonary thromboembolism].

Objective: To investigate the vicissitudes of the proportion and the mortality of patients with pulmonary thromboembolism (PTE).
Methods: To analyze respectively the data of 442 patients with PTE admitted to the Fuwai Hospital during the period 1974-2002 were analyzed retrospectively.
Results: The numbers of PTE in-patients every year during the 1970s and 48-79 cases in the early 2000s. The hospitalization constituent ratio of PTE was 0.1152% in 1970s and was 0.5866% in early 2000s. The age of onset ranged from 30 to 60. The tide age was from 30 to 60 in the male patients and from 40 to 60 in the female patients. The in-hospital mortality of PTE patients was descending from 20.0% in 1970s to 5.8% in early 2000s. The in-hospital mortality was 12.5% before 1990 and was 4.5% after 1990 (P = 0. 005). The in-hospital mortality rates of the male and female patients were 4.6% and 8.6% respectively (P = 0.09). The in-hospital mortality rates of the patients younger than 70 and elder than 70 were 5.5% and 19.0% respectively (P < 0.05).
Conclusion: PTE The mortality of PTE, which attacks males more frequently than females, and the proportions of the number of PTE in-patients to the number of the whole in-patients increased and the in-hospital mortality increased during the past 3 decades.
