摘要:

目的 研究25-(OH)D3与冠心病患者冠状动脉狭窄程度之间是否具有相关性。方法 接受了冠状动脉造影术(CAG)的216例患者,根据是否达到冠心病诊断标准与Gensini积分高低分为4组:对照组(43例)、轻度狭窄组(73例)、中度狭窄组(53例)、重度狭窄组(47例)。分别检测25-(OH)D3、总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、甘油三酯(TG)、肌酐(Cr)等指标。结果 4组在25-(OH)D3、男性、HDL-C、LDL-C、TC、TG的差异有统计学意义(P<0.05); 25-(OH)D3与Gensini积分存在负相关关系(r=-0.355, P<0.001);多元logistic回归提示:高水平的25-(OH)D3对于冠状动脉狭窄具有保护意义(B=-0.084, P<0.001);ROC曲线表明25-(OH)D3对于冠心病发生及冠状动脉严重狭窄具有较强的预测价值,前者曲线下面积(AUC)为0.74(95%CI:0.663~0.817), 最佳临界值为17.57 ng/ml, 敏感度为74.4%,特异度为72.3%;后者AUC为0.72(95%CI:0.636~0.804), 最佳临界值为11.42 ng/ml, 敏感度为63.8%,特异度为74.6%。结论 25-(OH)D3与冠状动脉狭窄程度之间呈负相关,较高水平的25-(OH)D3对冠状动脉狭窄具有一定的保护作用,对于重度狭窄的诊断能力明显强于轻度及中度狭窄。

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.
