In the Justification for Use of statins in Prevention: an Intervention Trial Evaluating Rosuvastatin (JUPITER), random allocation of rosuvastatin compared to placebo among primary prevention patients with a low-density lipoprotein cholesterol level of <130 mg/dl and a high-sensitivity C-reactive protein (hs-CRP) level of > or =2 mg/L resulted in a highly significant 44% reduction in major vascular events. However, the relation of baseline hs-CRP levels to risk within JUPITER has not previously been described and has been an area of controversy for study interpretation. As reported in the present study for the first time, despite enrolling patients with a constrained range of values, increasing baseline hs-CRP levels within JUPITER were nonetheless associated with increasing vascular risk in analyses treating hs-CRP as a continuous variable, as an ordinal variable, and as a threshold variable. As anticipated, the relative risk reduction associated with rosuvastatin was similar in magnitude across the tertile and threshold levels of entry hs-CRP. In conclusion, as the absolute risk increased with increasing hs-CRP, the absolute risk reduction associated with rosuvastatin within JUPITER was also greatest among those with the greatest entry hs-CRP levels.
在《使用他汀类药物预防的理由:评估瑞舒伐他汀的干预试验》(JUPITER)中,与安慰剂相比,在 LDL 胆固醇水平<130mg/dl 和高敏 C 反应蛋白(hs-CRP)水平≥2mg/L 的一级预防患者中,随机分配瑞舒伐他汀可使主要血管事件显著减少 44%。然而,hs-CRP 基线水平与 JUPITER 内风险的关系以前没有描述过,一直是研究解释的争议领域。正如本研究首次报告的那样,尽管纳入了具有约束值范围的患者,但在将 hs-CRP 作为连续变量、有序变量和阈值变量进行分析时,JUPITER 中 hs-CRP 水平的升高仍与血管风险的增加相关。正如预期的那样,hs-CRP 三分位和阈值水平的瑞舒伐他汀相关相对风险降低幅度相似。总之,随着 hs-CRP 的增加,绝对风险增加,因此 JUPITER 中与瑞舒伐他汀相关的绝对风险降低幅度也在 hs-CRP 水平最高的人群中最大。
