Abstract

Purpose of Review: To systematically examine the association between low-density lipoprotein cholesterol (LDL-C) and risk of hemorrhagic stroke. Recent Findings: A previous meta-analysis of prospective studies published in 2013 showed that higher concentrations of LDL-C were associated with lower risk of hemorrhagic stroke. Recently, seven large cohort studies were published examining LDL-C and risk of hemorrhagic stroke in different populations. Summary: Twelve prospective studies with 476,173 participants and 7587 hemorrhagic stroke cases were included in the current meta-analysis. The results showed that a 10 mg/dL increase in LDL-C was associated with 3% lower risk of hemorrhagic stroke (pooled relative risk [RR] 0.97, 95% confidence interval [CI] 0.95–0.98). The association appeared to be more pronounced in Asians (pooled RR 0.95, 95% CI 0.92–0.98), relative to Caucasians (pooled RR 0.98, 95% CI 0.97–1.00), with a p heterogeneity of 0.05 between two ethnic groups. Further genetic studies and clinical trials with a stricter safety monitoring strategy are warranted to understand the underlying pathogenesis and determine the treatment target of LDL-C range with the lowest risk of hemorrhagic stroke in different population groups.
