Abstract

Aim. To investigate the differences in prevalence of cardiovascular diseases between the plateau immigrants and inlanders in Chengdu and the distribution of cardiovascular diseases in the two kinds of people. Methods. 500 citizens of Chengdu, who were emigrated from Tibet, were employed in the study. Other 500 sex, age and living condition-matched people who were the native of Chengdu were used as controls. The diagnosis standard of cardiovascular diseases was based on Medicine Textbook. Chi-square test was used to analyze categorical variable. Results. The total prevalence rate of cardiovascular diseases, the prevalence rates of hypertension and rheumatic heart valve disease were 31.6%, 19.8% and 0% in the observational group respectively, significantly lower than those in the control group (42.0%, 26.4% and 2.4% respectively, X2=11.18, P < 0.005; X2=5.7645, P <0.01; X2=10.21, P <0.005). There was no difference between two groups in the prevalence of other cardiovascular disease (P > 0.05). The total prevalence rate of cardiovascular diseases in the male was 37.2% in the observational group, significantly lower than that in the control group (49.6%, X2=7.33, P <0.05). The incidence of cardiovascular diseases was increased with the age, which was most significant in the people aged 61-80 years old of the two groups. Conclusion. It is indicated that partial plateau hypertension falls to the normal degree after the patients left Tibet to Chengdu. The humid climate may be one of the independent factors inducing the episode of rheumatic heart valve disease. The prevalence rate of cardiovascular disease is related with the age.
