ATVB:同型半胱氨酸与静脉血栓栓塞相关

2021-06-02 MedSci原创 MedSci原创

血浆同型半胱氨酸水平升高与中老年妇女静脉血栓栓塞事件相关。在VTE亚型中,同型半胱氨酸与无诱因性事件相关。这些数据表明同型半胱氨酸在VTE的发展中可能发挥生物学效应。

病例对照研究已经明确血浆同型半胱氨酸是静脉血栓栓塞(VTE)的危险标志。但是,前瞻性数据十分少见,尤其是女性患者的数据。

近日,血管领域权威杂志Arteriosclerosis, Thrombosis, and Vascular Biology上发表了一篇研究文章,研究人员分析了2个大型前瞻性队列的女性血浆同型半胱氨酸是否与静脉血栓栓塞事件相关。

妇女健康研究(WHS)是一项前瞻性队列研究,纳入了27555名45岁以上且无心血管疾病和静脉血栓栓塞的妇女,研究人员评估了基线同型半胱氨酸浓度以及其他血栓生物标志物与未来静脉血栓栓塞(n=743)、肺栓塞(n=363)和深静脉血栓形成(n=545)之间的相关性。在妇女抗氧化和叶酸心血管研究(WAFACS)中,研究人员使用了2672名妇女(n=102例VTE事件)作为第二个队列,以证实该研究的结果。

同型半胱氨酸与VTE的相关性

在年龄校正分析中,同型半胱氨酸、hsCRP(高敏c反应蛋白)、纤维蛋白原和sICAM-1(可溶性细胞间黏附分子1)水平升高与VTE事件相关(极端四分位数比较P<0.05)。在调整了体重指数和其他传统VTE危险因素的多变量模型中,只有同型半胱氨酸与VTE的相关性持续存在(HRQ4为1.31 [95%CI为1.06-1.63])。高同型半胱氨酸水平与无诱因性肺栓塞(HRQ4为2.13 [95%CI为1.30-3.51])和深静脉血栓形成(HRQ4为1.59 [95%CI为1.05-2.40])相关,但与诱因性事件无关。在WAFACS研究中,高同型半胱氨酸水平也与VTE事件相关(趋势p=0.023)。

由此可见,血浆同型半胱氨酸水平升高与中老年妇女静脉血栓栓塞事件相关。在VTE亚型中,同型半胱氨酸与无诱因性事件相关。这些数据表明同型半胱氨酸在VTE的发展中可能发挥生物学效应
