Stroke:骨桥蛋白、新蝶呤和髓过氧化物酶与卒中复发的风险独立相关!

由此可见,骨桥蛋白、新蝶呤和髓过氧化物酶与卒中复发的风险独立相关,当将这些标志物加入到临床风险预测工具中可以提高个体的风险分类。

已知的危险因素不能完全识别有复发性卒中危险的患者。SPARCL试验(通过降低胆固醇水平预防卒中试验)评估了最近发生卒中或短暂性脑缺血发作以及未知的冠心病患者采用阿托伐他汀治疗后的卒中风险。近日,卒中领域权威杂志Stroke上发表了一篇研究文章,这项研究探讨了13种血浆生物标志物与卒中结局之间的关系。

研究人员对2176名参与者进行了一项病例队列研究,其中562人患有卒中,1614人为随机选择的无卒中患者。研究人员采用Cox比例风险模型评估了发生卒中的时间。

研究人员发现发生卒中的时间与脂蛋白相关磷脂酶A2、单核细胞趋化蛋白-1、抵抗素、基质金属蛋白酶-9、脑钠肽前体N端、可溶性血管细胞粘附分子-1、可溶性细胞间粘附分子-1或可溶性CD40配体无关。在调整后的分析中,骨桥蛋白(每变化一个SD的风险比为1.362;P<0.0001)、新蝶呤(风险比为1.137;P=0.0107)、髓过氧化物酶(风险比为1.177;P=0.0022)以及脂联素(风险比为1.207;P=0.0013)与卒中结局独立相关。在对脑卒中预后预测工具II和治疗、骨桥蛋白、新蝶呤和髓过氧化物酶进行调整后,其与卒中结局仍然存在独立相关。将这3种生物标志物加入到卒中预测工具II中使其受试者操作特征曲线下面积增加了0.023(P=0.015),得到了一个连续的净重新分类改善(29.1%;P<0.0001)和一个综合判别的改善(42.3%;P<0.0001)。

由此可见,骨桥蛋白、新蝶呤和髓过氧化物酶与卒中复发的风险独立相关,当将这些标志物加入到临床风险预测工具中可以提高个体的风险分类。
