摘要目的 探讨基线血清高敏C反应蛋白(hs-CRP)水平对新发脑出血风险的预测价值.方法 采用回顾性巢式病例对照研究方法,选择观察队列中新发脑出血患者323例,对照组646例.比较两组组间基线hs-CRP水平,分析不同基线hs-CRP水平对新发脑出血的风险.结果 新发脑出血患者基线hs-CRP水平(1.10 mg/L)高于对照组(0.66 mg/L,P<0.01);hs-CRP四分位数水平较高者(>2.12 mg/L)新发脑出血的风险是较低者(≤0.30 mg/L)的2.58倍(95%CI 1.77～3.76,P<0.01);对hs-CRP以3 mg/L及以第八十百分位点为临界值分组后进行统计分析,hs-CRP与新发脑出血风险的相关性依然存在,OR值分别为2.26(95%CI 1.60～3.20,P<0.01)和2.24(95%CI 1.60～3.13,P<0.01).结论 基线hs-CRP水平对新发脑出血有预测价值,基线hs-CRP水平较高者新发脑出血风险增加.

abstractsObjective To study the risk prediction for new intracerebral hemorrhage (ICH) with high sensitivity C-reactive protein ( hs-CRP) level. Methods In a retrospective, nested, case-controlled study, 323 cases of ICH were identified and matched with 646 controls. The hs-CRP levels at baseline were compared between the two groups. The relevance of different hs-CRP levels and the risk of ICH were analyzed. Results The ICH group had a higher median hs-CRP levels (1.10 mg/L) as compared with the control group (0. 66 mg/L) with significant difference ( P<0.01 ). In addition, the increase of risk associated with hs-CRP levels was primarily observed in the individuals with the highest quartile of hs-CRP levels(>2.12 mg/L). These patients had an increased risk of ICH (OR 2. 58, 95% CI 1. 77 to 3. 76) as compared with those in the lowest quartile(≤=0.30 mg/L). Individuals with basiline hs-CRP levels above the specified cut point of 3 mg/L ormore and those in the 80th percentile were at a markedly increased risk of ICH (for specified cut point of 3 mg/L,0R2.26, 95% CI 1.60-3.20, P<0.01; for 80th percentile, OR 2.24,95% CI 1.60-3.13, P <0.01, respectively). Conclusions Risk of ICH might be predicted with the level of hs-CRP. With the increase of hs-CRP level at baseline, the risk of ICH was increased.
