Objective To explore the risk factors for coronary heart disease using correlation analysis. Methods In this study

90 patients who were admitted to a hospital in Chongqing from April 2015 to March 2020 and received coronary angiography were selected as the research subjects

among whom 67 were males and 23 were females. According to the results of coronary angiography

the patients were divided into the observation group（n=60; coronary artery stenosis ≥ 50%

clearly diagnosed with coronary heart disease） and the control group（n=30; coronary artery stenosis was not seen

and coronary heart disease was not diagnosed）. Relevant data of the two groups including age

gender

past medical history（diabetes

hypertension）

history of smoking and the levels of total cholesterol（TC）

triglycerides（TG）

low-density lipoprotein cholesterol（LDL-C）

high-density lipoprotein cholesterol（HDL-C）

monocyte count as well as left ventricular ejection fraction（LVEF） were collected

and the correlation between these factors and coronary heart disease was analyzed. Results Logistic regression analysis showed that diabetes

a history of smoking and elevated LDL-C level were independent risk factors for coronary heart disease（P<0.05）. Conclusion Diabetes

a history of smoking and elevated LDL-C level are high risk factors for coronary heart disease. Therefore

actively controlling blood sugar

effectively quitting smoking and reducing LDL-C level can prevent the occurrence and development of coronary heart disease and reduce the incidence of later complications.
