Genetics of hypertension-related sex differences and hypertensive disorders of pregnancy.

Hypertension and hypertensive disorders of pregnancy (HDP) cause a significant burden of disease on societies and individuals by increasing cardiovascular disease risk. Environmental risk factors alone do not explain the observed sexual dimorphism in lifetime blood pressure (BP) trajectories nor inter-individual variation in HDP risk. In this short review, we focus on the genetics of hypertension-related sex differences and HDP and discuss the importance of genetics utilization for sex-specific hypertension risk prediction.

Sex-specific genetic risks for adverse outcomes after coronary revascularization procedures.

Men and women have differing risks of adverse events after revascularization procedures and these differences could be partially driven by genetics. We studied the sex-specific differences in associations of polygenic risk scores (PRSs) with atrial fibrillation (AF), ischaemic stroke (STR), intracranial haemorrhage (ICH), myocardial infarction (MI) and gastrointestinal haemorrhage (GIH) in coronary revascularization patients. The study cohort comprised 5561 and 17 578 revascularized women and men.

Associations of polygenic risk scores for preeclampsia and blood pressure with hypertensive disorders of pregnancy.

Background: Preexisting hypertension increases risk for preeclampsia. We examined whether a generic blood pressure polygenic risk score (BP-PRS), compared with a preeclampsia-specific polygenic risk score (PE-PRS), could better predict hypertensive disorders of pregnancy.

Methods: Our study sample included 141 298 genotyped FinnGen study participants with at least one childbirth and followed from 1969 to 2021.

Sex differences in coronary artery bypass grafting-related morbidity and mortality.

Background: Coronary artery bypass grafting (CABG) is associated with both cardiovascular disease (CVD) and non-CVD traits. In addition, women's prognosis after coronary events and revascularizations is worse than in men. As the course of CVD in women differs from that of men, we performed a phenome-wide analysis on the sex differences in CABG -related morbidity and mortality.

Motor potentials evoked by navigated transcranial magnetic stimulation in healthy subjects.

Navigated transcranial magnetic stimulation (TMS) is a tool for targeted, noninvasive stimulation of cerebral cortex. Transcranial stimuli can depolarize neurons and evoke measurable effects which are unique in two ways: the effects are caused directly and without a consciousness of the subject, and, the responses from peripheral muscles provide a direct measure for the integrity of the whole motor pathway. The clinical relevance of the method has not always been fully exposed because localizing the optimal stimulation site and determining the optimal stimulation strength have been dependent on time-consuming experimentation and skill.

Navigated transcranial magnetic stimulation and computed electric field strength reduce stimulator-dependent differences in the motor threshold.

The motor threshold (MT) is a fundamental parameter for evaluating cortical excitability in transcranial magnetic stimulation (TMS) despite remarkable variation, both within, and between subjects. We intended to test whether the variation could be reduced by targeting the stimulation on-line and modeling the TMS-induced electric field on individual MR images. Navigated TMS was used to map the primary motor cortex for the representation area of the thenar muscles (abductor pollicis brevis) and to determine the MT.
