Two studies found that isometric hand-grip (IHG) exercise significantly lowered systolic blood pressure in participants with hypertension. Additionally, IHG improved carotid artery distensibility, while having no effect on peripheral arteries. The researchers suggest that these improvements may be due to enhanced endothelial function.
A 20-year study found that high blood pressure is associated with a decline in cognitive function in both younger and older adults. The research emphasizes the importance of reducing blood pressure levels in younger individuals to prevent cognitive decline.

The molecule binds to receptors in the brain, leading to elevated blood pressure, which can also impair insulin release.
A recent study published in the Journal of Dental Education found that nearly half of patients with high blood pressure at a dental clinic had never been diagnosed. The researchers advocate for regular blood pressure screening in dental offices, which could help identify hypertension early and prevent related health issues.
Yale researchers found strong clinical evidence to support treating systolic blood pressure of at least 160 mm Hg in older adults. Treatment decisions should prioritize patient preferences and tolerance of therapy due to limited evidence on benefits.
Studies found strong evidence supporting treatment of systolic hypertension in older persons with SBP of at least 160 mm Hg. Treatment guidelines recommend thiazide diuretics and long-acting calcium channel blockers as first-line therapy for SH. Despite effectiveness, poor control of SH among patients is increasing.

The study has already made significant discoveries, including identifying key chemical signals that change stem cells into heart cells.
According to a recent study, approximately 65 million US adults now have hypertension, a 30% increase from the previous decade. The rise is largely due to the growing prevalence of obesity and an aging population.
A study of 154 hospitalized stroke patients found that antihypertensive therapy was used more frequently than recommended by clinical guidelines. The majority of patients experienced relative hypotension, and one in 20 developed frank hypotension.
