Hypertension:白细胞介素-1β抑制对血压、高血压发生和残余炎症风险的影响

2019-12-31 xing.T MedSci原创

这些结果表明,这种益处的潜在机制与血压变化或高血压无关。

尽管高血压和炎症在生理上是相互关联的,但针对炎症的治疗对血压的影响尚不确定。

近日,心血管权威杂志Hypertension上发表了一篇研究文章,最新的卡那单抗消炎性血栓形成结局研究(CANTOS)提供了机会,以检测白介素(IL)-1β抑制是否会降低血压,预防高血压,以及改变高血压与心血管事件之间的关系。 

CANTOS将10061例既往有心肌梗死且hsCRP(高敏C反应蛋白)≥2 mg/L的患者随机分配至卡那单抗 50 mg、150 mg、300 mg或安慰剂组。共有9549名试验参与者在随访过程中有血压记录。其中,80%曾诊断为高血压。在基线时没有高血压的患者中,hsCRP基线水平从最低到最高三分位数,每100人每年高血压发生率分别为23.4、26.6和28.1(P>0.2)。在所有参与者中,随访期间随机分配卡那单抗并没有降低血压(P>0.2)或发生高血压(风险比为0.96 [0.85-1.08],P>0.2)。卡那单抗抑制IL-1β可降低主要不良心血管事件发生率。

这些结果表明,这种益处的潜在机制与血压变化或高血压无关。
