ACS患者血清25(OH)D、TSH、CRP/ALB比值和PCT水平及其临床意义

目的 探讨急性冠状动脉综合征(acute coronary syndrome,ACS)患者血清25羟基维生素D[25 OH Vitamin D,25(OH)D]、促甲状腺激素(thyroid stimulating hormone,TSH)、C反应蛋白/白蛋白(C- reactive protein/Albmin,CRP/ALB)比值和降钙素原(procalcitonin,PCT)水平相关性的临床分析。方法 生化法等测定了126例ACS患者,其中67例不稳定性心绞痛(unstable angina pectoris,UAP)和59例急性心肌梗死(acute myocardial infarction,AMI),106例SAP患者和100例正常对照组(normal controls,NC)血清25(OH)D、TSH、CRP/ALB和PCT水平并进行对比性分析。受试者工作特征曲线(receiver operating characteristic curve,ROC curve)评估了ACS患者早期诊断的价值。结果 126例患者较之100例NC、106例SAP患者,血清25(OH)D水平明显降低( P <0.01),血清TSH、CRP/ALB和PCT水平明显增高( P 均<0.01)。ROC曲线显示:血清25(OH)D、TSH、CRP/ALB和PCT的临界值分别为15.36ng/mL、7.64mIU/L、4.36和0.45ng/mL,曲线下面积(area under the curve,AUC)分别为0.853、0.608、0.887和0.918,灵敏度83.0%~88.5%,特异性87.4%~ 92.4%。结论 血清25(OH)D、TSH、CRP/ALB和PCT水平具有早期诊断和鉴别诊断ACS的临床价值。
