JAHA:高敏感性C反应蛋白预测心血管疾病的风险!

2017-10-25 xing.T MedSci原创

hs-CRP的累积暴露与随后增加的CVD和心肌梗死风险呈剂量依赖关系。

高敏C反应蛋白(hs-CRP)这一指标与心血管疾病(CVD)风险增加有关。近日,心血管疾病领域权威杂志JAHA上发表了一篇研究文章,这项研究的目的是描述累积暴露于升高的hs-CRP与心血管事件发生之间的相关性。

在2006年,2008年和2010年,研究人员共3次测量了53065名参与者的hs-CRP水平。hs-CRP的累积暴露通过每个时间间隔的平均hs-CRP水平加权和(水平×时间)来计算得到。参与者分为非暴露组(3次检查中hs-CRP<3.0mg/L),1次暴露组(3次检查中有1次hs-CRP≥3.0mg/L),2次暴露组(3次检查中的2次hs-CRP≥3.0mg/L),3次暴露组(3次检查中均有hs-CRP≥3.0mg/L)。研究人员采用Cox比例风险模型评估累积hs-CRP与CVD事件之间的关联。

研究显示随着hs-CRP暴露的年数增加,患有CVD和心肌梗死风险与其呈剂量反应关系。3次暴露组的参与者CVD风险明显增加,风险比(95%可信区间)为1.38(1.11-1.72),而2次暴露组参与者为2.13(1.07-1.52),而1次暴露组参与者为1.13(0.97-1.31)(P<0.05);同时,对于心肌梗死也观察到相似和显著的相关性,其风险比(95%可信区间)分别为2.13(1.42-3.18),1.60(1.12-2.27)和1.57(1.17-2.10)。脑卒中和累积hs-CRP之间的关联无统计学意义(P=0.360)。

由此可见,hs-CRP的累积暴露与随后增加的CVD和心肌梗死风险呈剂量依赖关系。
