Circulating lipoprotein lipids, apolipoproteins and ischemic stroke
Researchers assessed the comparative effects of lipids and apolipoproteins on ischemic stroke in this Mendelian randomization (MR) study. Instrumental variables were single‐nucleotide polymorphisms correlated with low‐ and high‐density lipoprotein (LDL and HDL) cholesterol, triglycerides, and apolipoprotein A‐I and B (apoA‐I and apoB) at the level of genomewide significance in the UK Biobank. In the main and sensitivity univariable MR analyses, an association of increased levels of apoB, LDL cholesterol, and triglycerides with a higher risk of any ischemic stroke, large artery stroke, and small vessel stroke was seen. This MR study shows that apoB is the predominant trait that accounts for the etiological basis of apoB, LDL cholesterol, and triglycerides in relation to ischemic stroke, especially large artery and small vessel stroke. Whether HDL cholesterol has a protective effect on ischemic stroke independent of apoA‐I requires further study.
