Each day that your blood pressure is too high, your chances of having a stroke are increased. A stroke is a loss of brain function caused by a lack of blood to the brain. Stroke can result from the damage that ongoing high blood pressure causes in your vessels. If the affected vessel stops supplying blood to the brain, a stroke results.
High Blood Pressure Damages Blood Vessels
|
Vessels ThickenWhen blood presses against a vessel wall with too much force, muscles in the wall lose their stretch. This causes the wall to thicken, which narrows the vessel passage and reduces blood flow. |
Clots FormWhen blood pressure is too high, it can damage blood vessel walls. Fat and cholesterol (plaque) collect in the damaged spots. Blood cells stick to the plaque, forming a mass called a clot. A clot can block blood flow in the vessel. |
Vessels BreakSometimes blood flows with enough force to weaken a vessel wall. If the vessel is small or damaged, the wall can break. When this happens, blood leaks into nearby tissue and kills cells. Other cells may die because blood cannot reach them. |
