High Blood Pressure Linked to Higher Stroke Risk, Study finds
Advertisement
High blood pressure is known to increase a person's chances of having a stroke. A study led by Michigan Medicine focuses on the cumulative effects of years of high systolic blood pressure, the top number on a blood pressure reading, which indicates how hard the heart pumps blood to the arteries. The study, published in the journal JAMA Network Open, found that higher average systolic blood pressure during adulthood is linked to a greater risk for the two most common types of stroke.
Elevated blood pressure, or hypertension, affects the body by exerting excessive force on the walls of blood vessels. Over time, this constant pressure can damage arteries, leading to the formation of clots or causing them to rupture. This damage increases the risk of stroke, heart attack, and other cardiovascular diseases. Specifically, hypertension can cause the narrowing and hardening of arteries, reducing blood flow to critical areas such as the brain and heart.
