Abstract: Objective To analyze the prevalence of coronary heart disease （CHD） in high-risk population of cardiovascular disease in Tangshan area and its influencing factors, so as to provide reference for further prevention and treatment of cardiovascular disease. Methods From June 2020 to May 2021, the high-risk population of cardiovascular disease who completed the health examination in the physical examination center of a hospital in Tangshan City and screened according to the standard of high-risk population of cardiovascular disease were selected as the research objects to carry out the supplementary items related to CHD. The results were analyzed by descriptive analysis method, and the influencing factors of CHD in high-risk population of cardiovascular disease were analyzed by univariate and multivariate analysis methods. Results A total of 3 870 high-risk population of cardiovascular disease were included, of which 55.45% were males. Aged 40 - 78 years, with an average of （61.79 ± 8.10） years; body mass index （BMI） was 16.9 - 28.4 kg/m², with an average of （23.15 ± 2.36） kg/m²; 274 cases had a family history of CHD. Four hundred and six cases of CHD were detected, and the prevalence rate was 10.49%. Multivariate Logistic regression analysis showed that age （OR=2.079）, BMI （24.0-27.9 kg/m²： OR=1.754, ≥28.0 kg/m²： OR=2.675）, family history of CHD （OR=4.882）, hypertension （OR=2.812）, diabetes （OR=2.323）, drinking （OR=1.990）, shortage of physical activity （OR=1.245）, sleep time<6 h/d（OR=2.462）were the influencing factors of CHD in high-risk population of cardiovascular disease in Tangshan area. Conclusion The prevalence of CHD in high-risk population of cardiovascular disease in Tangshan is high. Based on the influential factors of CHD, the elderly, overweight or obese, family history of CHD, hypertension and diabetes should be emphasized, and the lifestyle intervention should be strengthened to reduce the prevalence of CHD.
