When a stroke occurs, blood circulation in the brain will be hindered, causing brain cells to be starved of oxygen or insufficient glucose supply, resulting in severe disability and disability. In severe cases, it may be life-threatening. High blood pressure is a high risk factor for stroke. It cannot be ignored. As for why high blood pressure can cause stroke? How to prevent stroke and high blood pressure?
What is high blood pressure?
According to the National Health Service of the Ministry of Health and Welfare, normal blood pressure is lower than 120/80mmHg, which means systolic blood pressure <120mmHg and diastolic blood pressure <80. If the blood pressure is between 120~139/80~89 mmHg, it is prehypertension ( Warning period), if blood pressure is not continued to be controlled, it will develop into hypertension. If the blood pressure is higher than 140/90mmHg, it is recommended to seek help from a doctor urgently.
Why does high blood pressure cause stroke?
Suffering from high blood pressure may compress the vascular system in any part of the body. In the long run, the blood vessels will become fragile, damaged and fragile. Once the blood vessels become inelastic, there will be a chance to form blockages and affect blood circulation, leading to ischemic stroke or hemorrhagic stroke. Stroke.
Some studies have shown that having high blood pressure increases the risk of stroke by 4 to 6 times. Sometimes high blood pressure may cause hardening of the large arteries, indirectly causing blockage of small blood vessels in the brain. The serious consequences are blood vessel swelling and even rupture. According to research, stroke is divided into the following two types:
- Ischemic stroke: Ischemic stroke is similar to heart disease, except that it occurs in the brain and is related to embolism in the brain or blood vessels leading to the brain. Because blood clots cause obstruction of blood circulation in the brain, most ischemic strokes It is caused by fat or cholesterol blocking blood vessels in the brain.
- Hemorrhagic stroke: High blood pressure and aneurysm are the most common causes of hemorrhagic stroke, which lead to rupture of cerebral blood vessels, damage to blood vessels, and ultimately damage to brain cells.
How to Treat a Stroke
Thrombus Terminator – Thrombust dissolving agent, tissue plasminogen kinase, is currently the only drug approved by the U.S. Food and Drug Administration (FDA) for the treatment of acute ischemic stroke. In addition, there are still many new drugs that can be used after a stroke to treat brain damage caused by a stroke.
It is often said that prevention is better than cure. By monitoring the risk factors for stroke, we can prevent the damage caused by stroke. Among them, atherosclerosis and hypertension are the ones that need to be strictly observed. In particular, the treatment of hypertension is to prevent stroke. The most efficient way.
