ObjectiveTo explore and discuss the risk factors of early onset coronary heart disease in Tibetan residents. MethodsWe selected Tibetan residents with coronary heart disease who were hospitalized in the Hospital of Chengdu Office of People's Government of Tibetan Autonomous Region between January 2011 and May 2013, and then divided them into two groups by age (early onset and late onset coronary heart disease groups). Univariate analysis was performed between two groups by gender, family history, smoking, drinking, hypertension, diabetes, levels of blood lipid, respectively. The factors with significant differences were extracted for logistic regression. Data analysis was performed using SPSS 16.0 software. ResultsA total of 64 Tibetan residents with coronary heart disease were included, of which, 22 cases were in the early onset groups and 42 cases the late onset group. The results of univariate analysis showed that, significant differences were found in gender, family history, and levels of HDL-C and LDL-C (all P < 0.05). Besides, the results of logistic regression showed that, family history (OR=3.374, P < 0.05), high triglycerides level (OR=2.369, P < 0.05), low HDL-C level (OR=0.014, P < 0.05) and high level of LDL-C (OR=3.008, P < 0.05) were independent risk factors of early onset coronary heart disease in Tibetan residents. ConclusionPositive family history, high triglycerides level, low HDL-C level and high level of LDL-C are independent risk factors of early onset coronary heart disease in Tibetan residents.
