A new study found that consuming just one cup of blueberries per day can significantly lower blood pressure and arterial stiffness in postmenopausal women with pre- and stage 1 hypertension. The findings suggest that blueberries may mitigate the negative cardiovascular effects of menopause, reducing the risk of cardiovascular disease.
Researchers found daily blueberry consumption resulted in significant reductions of both systolic and diastolic blood pressure in postmenopausal women with pre- and stage 1-HTN. The study suggests that blueberries may prevent the progression to full-blown hypertension, potentially through enhanced nitric oxide-mediated vasodilation.

A recent study by the American Heart Association found that following a healthy diet can lower blood pressure measurements. The research, which included over 12,000 volunteers, suggested that eating a balanced diet rich in fruits, vegetables, and whole grains may be an effective way to maintain healthy blood pressure levels.
The study found that more than half of US adults with high blood pressure now have readings below 140/90 mmHg. Despite progress, nearly half of those with hypertension remain uncontrolled, highlighting the need for increased efforts to prioritize blood pressure management at every medical visit.
Researchers found that using two drugs was no more effective than a single drug in slowing disease progression in people with autosomal dominant polycystic kidney disease (ADPKD). However, rigorous blood pressure treatment did slow the growth of kidney cysts and preserve kidney function.

A broad review of blood pressure medications found that mild control at 150 or less is sufficient for adults over 60, while more work is needed on older populations. The study's findings support a shift away from stricter guidelines, which prioritize younger adults.
A recent study found that home blood pressure monitors can be inaccurate, with systolic readings off by as much as 5mm Hg and diastolic readings off by as much as 10mm Hg in up to 30% of patients. The American Society of Nephrology recommends that all patients with home monitors get them validated with their healthcare providers.
Chronic mental stress, obesity, and inflammation contribute to excessive sodium retention in blacks, increasing the risk of heart damage. Researchers aim to develop effective therapeutic strategies to treat this condition by testing angiotensin receptor blockers and other treatments.
