JAHA:白细胞介素-6与急性冠脉综合征患者不良结局风险有关!

2017-10-25 xing.T MedSci原创

由此可见,在ACS患者中,IL-6浓度与不良心血管事件发生相关,并与已知的风险预测因子和生物标志物无关。这些发现支持IL-6作为不稳定性心脏病患者潜在的治疗靶点。

白细胞介素-6(IL-6)是涉及急性冠状动脉综合征(ACS)斑块不稳定性的炎性细胞因子。研究人员旨在评估IL-6在ACS后的预后意义,近日,心血管疾病领域权威杂志JAHA上针对这一问题发表了一篇研究文章。

研究人员测量了4939例参与SOLID-TIMI 52(使用达拉必利稳定斑块-心肌梗死溶栓治疗52)试验的受试者的基础IL-6浓度,SOLID-TIMI 52试验是一项在发生ACS小于30天的患者中采用达拉必利治疗的随机试验。患者被中位随访了2.5年;针对主要不良心血管事件(心血管死亡,心肌梗死或中风)和心血管死亡或心力衰竭住院治疗。首先对基线特征,ACS指数,ACS类型和随机治疗组的天数进行初步分析。

对于IL-6每增加一个SD,主要不良心血管事件的风险增高10%(调整后的风险比[adjHR]为1.10,95%可信区间[CI]为1.01-1.19)和心血管风险死亡或心力衰竭增加22%(adjHR为1.22,95%CI为1.11-1.34)。IL-6含量位于最高四分位数范围的患者发生主要不良心血管事件(Q4:Q1的adjHR为1.57,95%CI为1.22-2.03)和心血管死亡或心力衰竭(adjHR为2.29,95%CI为1.6-3.29)的风险较高 。在进一步调整生物标志物(高敏C反应蛋白,脂蛋白相关磷脂酶A2活性,高敏感性肌钙蛋白I和B型利尿钠肽)后,IL-6与主要不良心血管事件(Q4:Q1 的adjHR为1.43,95%CI 为1.09-1.88)和心血管死亡或心力衰竭(adjHR为1.79,95%CI为1.22-2.63)的风险显着相关。

由此可见,在ACS患者中,IL-6浓度与不良心血管事件发生相关,并与已知的风险预测因子和生物标志物无关。这些发现支持IL-6作为不稳定性心脏病患者潜在的治疗靶点。
