摘要:

目的 观察D⁃二聚体对肠道外抗凝药预防静脉血栓栓塞症(VTE)后发生肺血栓栓塞症(PTE 的预测价值。方法 选取 2020 5 月至 2021 6 月年在成都医学院第二附属医院呼吸与危重症医学科 的住院患者,对有 VTE 高风险或有抗凝指征且出血风险低的 94 例患者予肠道外预防性抗凝共 7 ~ 12 d 根据患者抗凝后 6 月内是否发生 PTE 分为 PTE 组和非 PTE 组,分析两组患者年龄、性别构成、Padua 评分及 抗凝前后血小板、肝功能、肾功能变化以及D二聚体的预测价值。结果 PTE组患者年龄(79.09 ± 6.78)岁高 于非 PTE 组(74.49 ± 10.45)岁(P < 0.05),PTE 组抗凝后 D 二聚体水平[2159.5(1252.25,4497.75)μg/L]明 显高于非 PTE 组[683.5(516,1 172.75)μg/L](P < 0.001),抗凝前 Padua 评分和 D 二聚体、抗凝前后血小 板、肝功能、肾功能指标在两组中无明显变化(P > 0.05)。非 PTE 组抗凝前后上述各项指标差异均无统计 学意义(P > 0.05),但非 PTE 组血小板、D 二聚体、谷草转氨酶及肌酐有下降或增高(P < 0.05)。年龄与抗 凝后的 D 二聚体呈正相关(rs = 0.266,P = 0.010);Padua 评分与抗凝前后的 D 二聚体均呈正相关(rs = 0.520 P < 0.001;rs = 0.236,P = 0.022)。抗凝后的 D 二聚体水平与是否发生 PTE 呈正相关(rs = 0.512,P < 0.001), ROC 曲线下面积为 0.849(95%CI:0.760 ~ 0.938,P < 0.001),最佳截断值为 1 026.5 μg/L,灵敏度 90.9%,特 异度 72.2%。结论 肠道外抗凝药预防 VTE D⁃二聚体水平在发生 PTE 组下降不明显,且较非 PTE 组显 著升高,高D⁃二聚体水平对半年内发生PTE 有较高的预测价值。

Abstract:

Objective To observe the predictive value of D⁃dimer in the prevention of pulmonary thrombo⁃ embolism(PTE)after venous thromboembolism(VTE)by parenteral anticoagulants. Methods Ninety⁃four patients with high risk of VTE or other conditions with anticoagulant indicators and low risk of bleeding were given parenteral prophylactic anticoagulation for 7 ~ 12 days from May 2020 to June 2021. According to whether with PTE within 6 months after anticoagulation,the patients were divided into PTE group and non⁃PTE group. Age,sex,Padua score changes of platelet,liver function,renal function and the predictive value of D ⁃ dimer were analyzed. Results Greater age in PTE group(79.09 ± 6.78)was found when compared with that in non⁃PTE group(74.49 ± 10.45 P < 0.05). The level of D⁃dimer in PTE group[2 159.5(1 252.25,4 497.75)(μg/L)]was significantly higher than that of non ⁃PTE group[683.5(516,1 172.75)(μg/L)](P < 0.001). There were no significant changes in Padua score before anticoagulation,and D⁃dimer,platelet,liver function and renal function before and after anti⁃ coagulation. There was no statistical difference in the above indexes before and after anticoagulation in the non⁃PTE group,but there were changes in platelet,D⁃dimer,aspartate transaminase and creatinine in the non⁃PTE group (P < 0.01 or P < 0.05). Age was positively correlated with D⁃dimer after anticoagulation(rs = 0.266,P = 0.010); Padua score was positively correlated with D⁃dimer before and after anticoagulation(rs = 0.520,P < 0.001;rs = 0.236 P = 0.022),and D ⁃ dimer level after anticoagulation was positively correlated with whether with PTE or not(rs = 0.512,P < 0.001). The area under ROC curve was 0.849(95%CI:0.760 ~ 0.938,P < 0.001);best cut off value1 026.5 μg/L,with sensitivity and specificity of 90.9%,and 72.2% respectively. Conclusion The level of D⁃dimer after the prevention of VTE by parenteral anticoagulantsin the PTE group does not decrease significantly but is significant higher than that in the non⁃PTE group.High D⁃dimer level has high predictive value for the occurrence of PTEwithin half a year.
