Women with hypertension achieve target blood pressures more easily than men, while older patients exhibit improved blood pressure control and lower risk of adverse events.
A new NIH clinical advisory statement recommends using systolic blood pressure as the primary criterion for diagnosing and treating hypertension in middle-aged and older Americans. This shift aims to improve outcomes by targeting systolic pressure, which is associated with a higher risk of heart disease.
The NHLBI has released a clinical advisory emphasizing the importance of systolic blood pressure in diagnosing and treating hypertension in middle-aged and older adults. The guideline recommends reducing systolic blood pressure to less than 140 mm Hg to reduce heart attack, heart failure, and stroke risk.
A new study finds that men with high blood pressure, weight and cholesterol levels in their 50s are more likely to develop vascular dementia in their late 70s. The research suggests that reducing these risk factors may help delay the onset of dementia, but more large-scale studies are needed to confirm the findings.
