血清脂蛋白 (a) [Lp(a) ]升高是缺血性中风 (IS) 的独立危险因素. 较高的Lp (a) 水平显著增加了IS的风险,特别是大动脉动脉硬化亚型.
科学领域:
- 心血管研究研究心血管研究
- 神经科学是一个神经科学.
- 生物化学 生物化学
背景情况:
- 脂蛋白 (a) [Lp(a) ]涉及到动脉动脉发生,血栓形成和纤维素分解受损.
- 血Lp (a) 的升高是动脉样硬化疾病进展的已知的危险因素.
- 脂蛋白和缺血性中风 (IS) 风险之间的联系是复杂的和争论的.
研究的目的:
- 调查血清Lp (a) 度与IS风险之间的关联.
- 确定Lp(a) 是否是IS及其子类型的独立风险因素.
主要方法:
- 一项前性病例控制研究,涉及231名急性IS患者和163名对照.
- 收集的人口,临床和实验室数据,包括血清Lp (a) 水平.
- 通过四分位数和TOAST分类分析了Lp(a) 度和分层风险.
主要成果:
- 血清Lp (a) 在IS病例中 (81.81nmol/L) 与对照 (59.75nmol/L) 相比显著更高.
- 增加的Lp (a) 水平 (Q4与Q1) 与2.23倍更高的IS风险相关 (OR2.23;p=0.008).
- 血平率>75nmol/L与大动脉动脉样硬化中风风险增加2.4倍 (OR2.4;p=0.001),即使经过对其他风险因素进行调整.
结论:
- 血清Lp (a) 是缺血性中风的独立风险因素.
- Lp (a) 是一个重要的风险因素,特别是在大动脉动脉样硬化亚型的IS.
