尽管Pemafibrate降低了残留胆固醇,但PROMINENT试验显示了对Pemafibrate的中性结果. 增加的LDL胆固醇和阿波利波蛋白B水平可能解释了这些心血管结局试验结果.
科学领域:
- 心脏病学 心脏病学
- 生物化学 生化学
- 临床试验 临床试验
背景情况:
- 在PROMINENT试验中,研究了一种降脂剂pemafibrate,该药物具有中性心血管结果.
- 尽管降低了甘油三和残留胆固醇,但pemafibrate并没有显著影响心血管事件.
研究的目的:
- 测试假设,残余胆固醇,LDL胆固醇和阿波利波蛋白B的绝对变化解释了PROMINENT试验的中性结果.
- 为了分析大量人群队列中的脂质和非脂蛋白变化,模仿PROMINENT试验设计.
主要方法:
- 来自哥本哈根一般人口研究 (CGPS) 的108,431个个体的分析,符合PROMINENT试验纳入标准.
- 模仿PROMINENT试验设计,以估计动脉样硬化心血管疾病 (ASCVD) 终点的危险比率.
- 计算与残余胆固醇,LDL胆固醇和阿波利波蛋白B的特定绝对变化相关的危险比率.
主要成果:
- 在PROMINENT中进行的血纤维化治疗: -7 mg/dL残留胆固醇, +10 mg/dL的LDL胆固醇, +5 mg/dL的阿波利波蛋白B.
- 在CGPS模拟中:ASCVD的危险比为0.97 (残留胆固醇),1.04 (LDL胆固醇) 和1.02 (阿波利波蛋白B).
- 脂质和阿波利波蛋白B的综合绝对变化在CGPS模拟中产生了1.05的估计ASCVD危险比率.
结论:
- 剩余胆固醇,LDL胆固醇和阿波利波蛋白B的绝对质量变化解释了PROMINENT试验的结果.
- 增加的全动脉质胆固醇和阿波利波蛋白B水平可能会解释 pemafibrate 臂中更多的ASCVD 的趋势.
