摘要: 目的 分析血管性血友病因子(vWF)对老年慢性心力衰竭(CHF)患者发生下肢静脉血栓的预测价值。方法 选取96例老年CHF患者,以其中37例合并下肢静脉血栓的患者为疾病研究组,59例未合并下肢静脉血栓的患者为疾病对照组,另选取50名>60岁的体检健康者为正常对照组。收集96例老年CHF患者一般临床资料,检测所有研究对象vWF活性、D-二聚体、凝血功能等指标。采用Logistic回归分析评价CHF并发下肢静脉血栓的影响因素。采用受试者工作特征(ROC)曲线评估血浆vWF活性诊断老年CHF患者发生下肢静脉血栓的效能。结果 与疾病对照组比较,疾病研究组vWF活性显著升高(P<0.05)。Logistic回归分析结果显示,vWF活性是CHF患者并发下肢静脉血栓的风险因素。以231.5%为最佳临界值,血浆vWF活性诊断老年CHF并发下肢静脉血栓的敏感性为78.6%,特异性为82.6%。结论 血浆vWF活性对评估老年CHF患者并发下肢静脉血栓风险有一定的临床价值。

Abstract: Objective To analyze the predictive value of von Willebrand factor(vWF) for venous thrombosis in elderly patients with chronic heart failure(CHF). Methods A total of 96 elderly patients with CHF were enrolled. Among them,59 patients with CHF without lower extremity venous thrombosis were enrolled in disease control group,and 37 patients with chronic heart failure complicated with lower extremity venous thrombosis were enrolled in disease study group. Totally,50 healthy subjects over 60 years old during the same period were enrolled in healthy control group. The general clinical data were collected,and vWF activity,D-dimer and coagulation function related indexes were determined. Logistic regression analysis of influencing factors for venous thrombosis in patients with CHF was performed. The efficiency of plasma vWF activity on lower extremity venous thrombosis in elderly patients with CHF was evaluated by receiver operating characteristic(ROC) curve. Results The vWF activity was higher in disease research group than that in disease control group(P<0.05). Logistic regression analysis showed that vWF activity was an independent risk factor for lower extremity venous thrombosis in patients with CHF. The diagnostic cut-off value of plasma vWF activity for CHF complicated with lower extremity venous thrombosis was 231.5%,the sensitivity was 78.6%,and the specificity was 82.6%. Conclusions Plasma vWF activity level has clinical value in assessing the risk of lower extremity venous thrombosis in elderly patients with CHF.
