However, causality of these associations remains unclear. This study employed 2-sample univariate and multivariate Mendelian randomization (MR) to assess the causal connection between HDP and stroke.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Genetic variants for HDP and two subtypes were identified from recent large-scale genome-wide association studies and the FinnGen consortium. Stroke summary data were obtained from the MEGASTROKE consortium. The primary analytical approach for univariate MR was the inverse variance weighting method. Sensitivity analyses incorporated methods such as MR-Egger regression, weighted median, and maximum likelihood to ascertain the robustness of the results. Additionally, multivariable MR analyses were conducted to account for potential associative effects of hypertension and type 2 diabetes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Genetically predicted HDP was associated with a high risk of large artery atherosclerosis (odds ratio [OR]=1.50, 95% confidence interval [CI]: 1.17\u20131.91, <jats:italic>P<\/jats:italic>=1.13\u00d710<jats:sup>-3<\/jats:sup>) and small vessel stroke (OR=1.29, 95% CI: 1.20\u20131.50, <jats:italic>P<\/jats:italic>=1.52\u00d710<jats:sup>-3<\/jats:sup>).

An elevated risk of small vessel stroke (OR=1.20, 95% CI: 1.01\u20131.43, <jats:italic>P<\/jats:italic>=3.74\u00d710<jats:sup>-2<\/jats:sup>) and large artery atherosclerosis (OR=1.22, 95% CI: 1.01\u20131.47, P=4.07\u00d710<jats:sup>-2<\/jats:sup>) may be related with genetically predicted susceptibility to gestational hypertension. Genetically predicted susceptibility to preeclampsia or eclampsia may be associated with an increased risk of stroke (OR = 1.10, 95% CI: 1.02\u20131.19, <jats:italic>P<\/jats:italic> = 1.16\u00d710<jats:sup>-2<\/jats:sup>) and ischemic stroke (OR = 1.10, 95% CI: 1.02\u20131.20, <jats:italic>P<\/jats:italic> = 1.84\u00d710<jats:sup>-2<\/jats:sup>).
