Abstract:Objective To investigate the correlation between osteoporosis and the severity of coronary artery disease, and to provide a relevant scientific evidence for the screening of high-risk groups of CHD at early stage.Methods From January 2015 to January 2017, 300 patients with coronary heart disease were treated with coronary angiography for the first time in our hospital. The results of bone mineral density measurement were analyzed retrospectively and divided into osteoporosis group (n = 102) and non osteoporosis group (n = 198). The correlation between osteoporosis and the severity of coronary artery disease (the degree of coronary stenosis and the degree of coronary artery calcification) was analyzed. Results The degree of coronary stenosis in the osteoporotic group was significantly higher than that in the non osteoporosis group, and the difference was statistically significant (P < 0.05);proportion of osteoporosis in patients with single vessel coronary artery disease was lower than the non osteoporosis group, and that of multivessel coronary disease was higher in osteoporosis group (P < 0.05); osteoporosis group of patients with coronary artery calcification was significantly higher than non osteoporosis group, the difference was statistically significant (P < 0.05); proportion of osteoporosis group was less than the non osteoporosis patients for mild calcification osteoporosis while proportion of moderate and severe calcification were higher in osteoporosis group (P < 0.05); osteoporosis was positively correlated with the degree of coronary stenosis and coronary artery calcification (P < 0.05). Logistic regression analysis showed that osteoporosis was an independent risk factor for coronary heart disease. Conclusions Osteoporosis is related to the degree of coronary stenosis and coronary artery calcification, and is closely related to the severity of coronary artery disease.
