Research on hypertension in special populations has revealed critical insights into genetic factors and treatment efficacy. Shi et al. investigated the impact of plateletcrit and MTHFR genotypes on the efficacy of folic acid in stroke prevention, finding that specific genetic profiles significantly influenced treatment outcomes, with a notable 66% reduction in first stroke risk among certain subgroups (ref: Shi doi.org/10.1038/s41392-024-01817-0/). In a secondary analysis of the ADAMPA trial, Martínez-Ibáñez et al. assessed the long-term effects of home blood pressure self-monitoring combined with medication self-titration, concluding that this approach effectively reduced blood pressure without increasing healthcare utilization or adverse events, highlighting its potential for managing hypertension in diverse populations (ref: Martínez-Ibáñez doi.org/10.1001/jamanetworkopen.2024.10063/). Additionally, the study by Ronksley et al. on emergency department use among dialysis patients identified clinical and sociodemographic factors contributing to potentially preventable visits, emphasizing the need for tailored interventions in this vulnerable group (ref: Ronksley doi.org/10.1001/jamanetworkopen.2024.13754/). These findings collectively underscore the importance of personalized approaches in hypertension management, particularly in populations with unique genetic and health profiles.

The interplay between kidney health and hypertension has been a significant focus of recent studies, particularly regarding the effects of various treatments on kidney function. Perkovic et al. demonstrated that semaglutide significantly slowed the decline of kidney function in patients with type 2 diabetes and chronic kidney disease, highlighting its potential to reduce cardiovascular risks associated with renal impairment (ref: Perkovic doi.org/10.1056/NEJMoa2403347/). Colhoun et al. further supported this notion in the SELECT trial, where semaglutide was shown to positively impact kidney outcomes, reinforcing its dual role in managing both obesity and cardiovascular disease (ref: Colhoun doi.org/10.1038/s41591-024-03015-5/). Garg et al. conducted a cohort study comparing living kidney donors and nondonors, finding that while both groups had similar hypertension rates, donors exhibited a slower decline in eGFR, suggesting that living donation may have long-term renal benefits despite initial eGFR drops (ref: Garg doi.org/10.1001/jama.2024.8523/). Additionally, Wang et al. explored the effects of heat exposure on maternal hypertension and its implications for preterm birth, indicating that environmental factors can significantly influence both maternal and fetal health outcomes (ref: Wang doi.org/10.1038/s41591-024-03002-w/).
