JAHA:静脉血栓栓塞后肺动脉高压的发生率和危险因素

2022-07-17 MedSci原创 MedSci原创

在这一项大型的真实世界的VTE人群中,3.5%的患者在最初的VTE事件发生后的2年内发生PH。随着年龄的增长,在发生静脉血栓栓塞事件时有其他合并症的女性中,风险较高。

肺动脉高压(PH)是肺栓塞一种致命性的潜在并发症,表现为静脉血栓栓塞(VTE)。既往有静脉血栓栓塞者PH的发生率和危险因素尚未明确。

近日,心血管疾病领域权威杂志JAHA上发表了一篇研究文章,研究人员采用来自MarketScan管理数据库2011-2018年期间住院和门诊医疗索赔的国际疾病分类(ICD)代码识别静脉血栓栓塞的病例、静脉血栓栓塞事件前的合并症以及静脉血栓栓塞事件后发生的PH。研究人员计算了累积发生率和风险比(HR)及其95%CI。

纳入分析的170021例VTE患者平均(±SD)年龄为57.5±15.8岁,其中50.5%为女性。在平均1.94年的随访期间,累计共有5943例PH病例。发生VTE后2年,PH的累积总体发生率(95%CI)为3.5%(3.4%-3.7%)。老年患者(3.9%[3.8%-4.1%])高于男性(3.2%[3.0%-3.3%]),肺栓塞(6.2%[6.0%-6.5%])高于仅存在深静脉血栓的患者(1.1%[1.0%-1.2%])。调整年龄和性别后,伴有潜在合并症的静脉血栓栓塞患者发生PH的风险更高。使用Charlson合并症指数可观察到剂量-反应关系,评分越高,PH风险越高(评分≥5 vs. 0:HR(2.50[2.30-2.71]))。在评估单一合并症时,其与心衰(HR为2.17[2.04-2.31])、慢性肺部疾病(HR为2.01[1.90-2.14])和酗酒(HR为1.66[1.29-2.13])的相关性最强。

由此可见,在这一项大型的真实世界的VTE人群中,3.5%的患者在最初的VTE事件发生后的2年内发生PH。随着年龄的增长,在发生静脉血栓栓塞事件时有其他合并症的女性中,风险较高。这些数据为了解静脉血栓栓塞患者的PH负担和PH的危险因素提供了深入的见解。
