Two studies examined the effectiveness of CPAP treatment in reducing cardiovascular outcomes in adults with obstructive sleep apnea (OSA). Despite finding no significant reduction in hypertension or cardiovascular events, the studies suggest that OSA may be an independent risk factor for developing new-onset hypertension.
Researchers found that hunter-gatherers like the Tsimane people in Bolivia have lower age-related increases in blood pressure and less risks of atherosclerosis. The Tsimane diet is high in fruits, vegetables, and potassium, and low in calories, salt, and alcohol. This study challenges traditional views on modernization's impact on health.

Researchers have discovered a molecular pathway that can help reduce cardiac damage caused by an enlarged heart, a common result of hypertension or a heart attack. The pathway, activated by stretch of adult cardiac cells, promotes the release of VEGF, which protects cardiac function and keeps cells alive.

Researchers found that more than one-quarter of Canadian adults will be diagnosed with hypertension by 2012/13. Higher rates were observed in women older than 65 and in the Atlantic provinces.
A mid-pregnancy test can predict preeclampsia, a late-pregnancy disorder characterized by high blood pressure and excess protein in the urine. Women with high blood pressure during pregnancy are at increased risk of experiencing high blood pressure, kidney problems, and stroke later in life.
A study co-authored by University of Leicester expert identifies key genetic mechanisms controlling blood pressure, including two microRNAs that regulate renin hormone production. This breakthrough could lead to innovative new treatments for high blood pressure.
A new study published in Neurology found that a person's stroke risk profile can also predict their risk of developing memory and thinking problems later in life. The researchers followed 23,752 people with an average age of 64 and found that those with higher stroke risk profiles were more likely to develop cognitive problems.
A recent study by the National Institutes of Health has discovered a correlation between high blood pressure and stroke risk factors with cognitive impairment. The research, which followed over 30,000 participants, found that age, left ventricular hypertrophy, and high blood pressure were independent predictors of cognitive decline.
Research suggests a link between high blood pressure and reduced ability to recognize emotional faces and texts, potentially causing miscommunication and increased distress in social situations. This 'emotional dampening' can lead to distrust, risk-taking behavior, and worsened mental health conditions.
