Abstract:
Objective:To explore the prevalence and risk factors of cardiac events in different ethnic groups in Xinjiang region.Methods:This retrospective cohort study was based on big data from the health checkup population. A total of 7 899 cases were included from the Physical Examination Center of Xinjiang Uygur Autonomous Region People′s Hospital form 2015 January 1 to December 31, 2017.The population were divided into Uyghur group (2 630 cases), Kazak group (2 636 cases), and the Han nationality group (2 633 cases). Telephone follow-up was conducted once a month after the health checkup, the preset follow-up time for all personnel was 2 years, with the occurrence of cardiac events as the end point. Once cardiac events occurred, the follow-up would be stopped. The risk factors of cardiac events in different ethnic groups were evaluated by statistical analysis.Results:The median follow-up time of the 7 899 included healthy examinees was 1.27 years, and 200 cases of cardiac events occurred, with an incidence rate of 2.53%. The values of body mass index (BMI), the levels of triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) of Uyghur and Kazak were higher than those of Han (all P<0.05). The cardiac events in Uyghur, Kazak and Han group were 75 cases (2.85%), 85 cases (3.22%) and 40 cases (1.52%). There was no significantly statistical difference between Uyghur group and Kazak group in the incidence of cardiac events, while it was significantly lower in the Han group than the other two groups (both P<0.05). Univariate analysis showed that BMI, TC, TG, HDL-C and LDL-C were the risk factors of cardiac events; multivariate Cox regression analysis showed that ethnic groups ( HR=4.34, 95% CI: 1.14―8.13); HDL-C ( HR=3.32, 95% CI: 1.89―5.74) and LDL-C ( HR=2.47, 95% CI: 1.21―7.45) were independent risk factors for cardiac events. Conclusions:Ethnic factor is one of the independent risk factors for the occurrence of cardiac events in Xinjiang, and Uyghur and Kazak have a higher incidence of cardiac events. HDL-C and LDL-C are also important risk factors for cardiac events.
