Abstract:
We used two‐sample Mendelian randomization (MR) to examine the effects of blood lipids and lipid‐modifying drugs on intracranial aneurysm (IA). Methods Genetic variants for the effects of high‐density lipoprotein cholesterol (HDL‐C), apolipoprotein A1, low‐density lipoprotein cholesterol (LDL‐C), apolipoprotein B, and triglycerides and targets for lipid‐modifying drugs were selected from the genome‐wide discovery analyses of the UK Biobank. Summary‐level data on IAs were obtained from the International Stroke Genetics Consortium. Univariate and multivariate MR analyses were performed. Results Univariate MR analyses showed that the HDL‐C was negatively correlated with IA (odds ratio [OR] = 0.816, 95% confidence interval [CI] = 0.715–0.932, p = 0.003) and ruptured IA (rIA; OR = 0.775, 95% CI = 0.663–0.906, p = 0.001). The multivariate MR–inverse variance weighted analysis showed that the HDL‐C was negatively correlated with IA (OR = 0.655, 95% CI = 0.434–0.988, p = 0.043) and rIA (OR = 0.563, 95% CI = 0.347–0.913, p = 0.02), and the LDL‐C was negatively correlated with IA (OR = 0.402, 95% CI = 0.191–0.848, p = 0.017) and rIA (OR = 0.376, 95% CI = 0.160–0.883, p = 0.025). Using genetic proxies of known lipid‐modifying drugs, we found that the increased HDL‐C with cholesterol ester transfer protein proxies was associated with a decreased risk of rIA (OR = 0.852, 95% CI = 0.747–0.973, p = 0.018), and the decreased LDL‐C with 3‐hydroxy‐3‐methylglutaryl‐coenzyme A reductase proxies was associated with increased risk of IA (OR = 1.772, 95% CI = 1.080–2.908, p = 0.024) and rIA (OR = 1.856, 95% CI = 1.022–3.371, p = 0.042). Conclusions Genetically determined HDL‐C and LDL‐C reduce the risk of IA and rIA. The effects of different lipid‐modifying drugs on IA need to be further investigated.
