Third Heart Number Affects Brain Health
14 Jun
Summary
- Pulse pressure, a third vital sign, measures artery flexibility.
- High pulse pressure is linked to dementia and heart disease risk.
- Lowering blood pressure can also reduce pulse pressure.
A third vital sign, pulse pressure, is emerging as a significant indicator for both cardiovascular and brain health. This metric, representing the difference between systolic and diastolic blood pressure, reveals the elasticity of arteries. Elevated pulse pressure, often exceeding 40 mm Hg, signifies stiffened blood vessels and is linked to increased risks of heart disease, stroke, and cognitive decline.
New research published on June 3 in *Neurology* highlights a connection between high pulse pressure and a heightened risk of dementia-related death. While not always a focus for diagnosis, a pulse pressure above 40 mm Hg can be concerning, with some guidelines considering over 60 mm Hg a heart disease risk, particularly in older adults.
Fortunately, pulse pressure is modifiable. Strategies for managing high blood pressure, such as adhering to the DASH diet and regular exercise, can also help lower pulse pressure. Experts emphasize that controlling this metric is crucial for long-term protection of both heart and brain health.
