Eur Respir J:无诱因肺栓塞后复发性静脉血栓栓塞的危险因素分析!

2018-01-08 xing.T MedSci原创

在首次无诱因肺栓塞后,肺栓塞的诊断时的年龄、PVOI或抗凝治疗6个月以及抗磷脂抗体阳性被认为是VTE复发的独立预测因子。

近日,呼吸疾病领域权威杂志Eur Respir J上发表了一篇研究析文章,研究人员旨在明确无诱因肺栓塞后发生复发性静脉血栓栓塞(VTE)的危险因素。

该研究的分析是基于PADIS-PE随机双盲试验,其纳入了371例首次无诱因肺栓塞的患者,这些患者在开始6个月后随机接受华法林或安慰剂进行额外治疗18个月 ,并且在研究治疗停药后随访2年。所有患者接受了肺通气/灌注扫描(在抗凝治疗6 个月)。

中位随访41个月期间,371例患者中有67例患者发生VTE复发(6.8次事件每100人每年)。在多变量分析中,年龄为50-65岁的受试者,VTE复发的风险比为3.65(95%可信区间为1.33-9.99),年龄>65岁的受试者,VTE复发的风险比为4.70(95%可信区间为1.78-12.40),6个月时肺血管阻力指数(PVOI)≥5%的受试者,VTE复发的风险比为2.06(95%可信区间为1.14-3.72),抗磷脂抗体阳性受试者,VTE复发的风险比为2.38(95%可信区间为1.15-4.89)。当考虑到6个月时的PVOI在实践中不可用,在肺栓塞诊断时PVOI≥40%(40%的患者)也与复发风险增加2倍相关。

在首次无诱因肺栓塞后,肺栓塞的诊断时的年龄、PVOI或抗凝治疗6个月以及抗磷脂抗体阳性被认为是VTE复发的独立预测因子。
