Abstract:

Objective To study the correlation between 25-(OH)D3 and the degree of coronary artery stenosis in patients with coronary heart disease(CHD).Methods Totally 216 patients who underwent coronary angiography(CAG) were divided into control group (43 cases), mild stenosis group (73 cases), moderate stenosis group (53 cases), and severe stenosis group (47 cases) on the basis of the diagnostic criteria for CHD and the Gensini score. The key observations were 25-(OH)D3, total cholesterol(TC), high density lipoprotein-cholesterol (HDL-C), low-density lipoprotein cholesterol(LDL-C), triglyceride(TG), creatinine(Cr) and other indicators. Results Among the four groups, the differences were statistical significance in 25-(OH)D3, male, HDL-C, LDL-C, TC and TG (P<0.05). 25-(OH)D3 was negatively correlated with Gensini score (r=-0.355, P<0.001). Multiple logistic regression showed that high 25-(OH)D3 was protective against coronary stenosis (B=-0.084, P<0.001). Receiver operating characteristic(ROC) curve showed that 25-(OH)D3 had strong predictive value for the occurrence of CHD and severe coronary stenosis. Area under curve(AUC) of the former and the latter was respectively 0.74(95%CI: 0.663-0.817) and 0.72 (95%CI: 0.636-0.804),respectively; the optimal cut-off value was 17.57 ng/ml and 11.42 ng/ml, the sensitivity was 74.4% and 63.8%, and the specificity was 72.3% and 74.6%.Conclusion 25-(OH)D3 had negative correlation with the degree of coronary stenosis. Higher 25-(OH)D3 had a certain protective effect on coronary stenosis. The diagnosis for severe stenosis is significantly higher than for mild and moderate.
