The role of lipoprotein-A [Lp (a)] as a risk factor for stroke is less well documented than for coronary heart disease. Hence, we conducted a systematic review and meta-analysis for the published observational studies in order to investigate the association of Lp (a) levels with the risk of stroke and its subtypes. In our meta-analysis, 41 studies involving 7874 ischemic stroke (IS) patients and 32,138 controls; 13 studies for the IS subtypes based on TOAST classification and 7 studies with 871 Intracerebral hemorrhage (ICH) cases and 2865 control subjects were included. A significant association between increased levels of Lp (a) and risk of IS as compared to control subjects was observed (standardized mean difference (SMD) 0.76; 95% confidence interval (CIs) 0.53-0.99). Lp (a) levels were also found to be significantly associated with the risk of large artery atherosclerosis (LAA) subtype of IS (SMD 0.68; 95% CI 0.01-1.34) as well as significantly associated with the risk of ICH (SMD 0.65; 95% CI 0.13-1.17) as compared to controls. Increased Lp (a) levels could be considered as a predictive marker for identifying individuals who are at risk of developing IS, LAA and ICH.
脂蛋白-A [Lp(a)] 作为中风风险因素的作用不如冠心病那么有充分的文献记载。因此,我们进行了系统评价和荟萃分析,以调查发表的观察性研究中 Lp(a) 水平与中风及其亚型风险之间的关联。在我们的荟萃分析中,纳入了 41 项研究,涉及 7874 例缺血性中风 (IS) 患者和 32138 名对照者;基于 TOAST 分类的 IS 亚型的 13 项研究和 871 例颅内出血 (ICH) 病例和 2865 名对照者的 7 项研究。与对照组相比,Lp(a) 水平升高与 IS 风险显著相关(标准化均数差 (SMD) 0.76;95%置信区间 [CI] 0.53-0.99)。还发现 Lp(a) 水平与 IS 的大动脉粥样硬化 (LAA) 亚型风险显著相关(SMD 0.68;95%CI 0.01-1.34),与对照组相比,Lp(a) 水平与 ICH 风险也显著相关(SMD 0.65;95%CI 0.13-1.17)。升高的 Lp(a) 水平可被视为识别易发生 IS、LAA 和 ICH 的个体的预测标志物。
