Stroke is a condition that occurs when cerebral blood vessels are blocked or ruptured. Once it occurs, cells in the brain will die quickly, and the body parts controlled by this part of the brain tissue will not work properly and may be disabled. If the scope is wide Will cause death.
A stroke is important. Every second is important , The faster brain cell death is reduced, the more likely it is to get a good knotfruit.
There are 5 signs of stroke, and people will be unable to complete 3 simple actions.
Symptoms of stroke may include:
- Sudden numbness or weakness , Especially on one side of the body;
- Sudden changes in vision or difficulty swallowing;
- Suddenly have a severe headache of unknown origin;
- Suddenly dizzy and difficult to walk , Or balance disorder;
- Suddenly confused thinking, unable to speak or understand others.
Give instructions to smile, raise arms, or ask questions to see if the following symptoms occur:
- Face: When smiling, does one side of the face droop?
- Arm: When the arm is raised, is one side lower than the other side?
- Language: Don’t repeat a simple sentence.obstacle?
If so, don’t delay a second, call 120 for first aid! ! !
How much time is left for rescue after stroke?
Stroke treatment needs to race against time. Once the brain cells are deprived of oxygen, they will die immediately.
About 90% of strokes are ischemic, that is, the cerebrovascular is blocked by thrombus. Thrombolytic drugs can prevent stroke from harming the brain, but it takes 3 hours after stroke symptoms appear (Some people can extend to 4.5 hours) use immediately.
There are two main types of stroke. Thrombus and blood pressure are the culprits.
There are two main types of stroke: ischemic and hemorrhagic. The treatment methods are different. After the signs of stroke appear, brain CT and related examinations can determine whether the stroke is caused by a clogged blood vessel or a ruptured blood vessel.
1. Ischemic stroke
Ischemic stroke is the most common type of stroke, and nearly 9/10 strokes belong to this type. The direct cause is that blood clots block blood vessels in the brain.
The deep-seated reason is mostly atherosclerosis. There is fat in the arterial wallPlaques, these plaques fall off and enter the blood circulation to form thrombus.
Thrombus blocking the cerebrovascular vessels will lead to stroke and thrombosis It may originally be in the brain, or it may circulate through blood vessels in other parts of the brain to reach the cerebral vessels.
Treatment mainly uses drugs to promote blood circulation, such as thrombolytic drugs.
2. Hemorrhagic stroke
Also called cerebral hemorrhage or cerebral hemorrhage. This type of stroke is rare, but it is extremely fatal. The direct cause is the rupture of blood vessels in the brain. As a result, bleeding inside the brain is difficult to stop.
The deep-seated reason is that hypertension is not controlled, causing fragile arteries to rupture.
Treatments usually include control of hypertension, bleeding and brain swelling.
Three types of people are prone to stroke, and there are 4 ways to prevent stroke
1. People with stroke-related chronic diseases
Certain chronic diseases increase the risk of stroke, including high blood pressure, high cholesterol, diabetes and obesity.
2. Many bad behaviors
Some behaviors increase the risk of stroke, such as smoking, lack of exercise and alcoholism.
3. High-fat, high-salt and high-calorie diet
Eating too much fat and cholesterol can cause arterial narrowing. Too much salt can cause high blood pressure. Excessive calories can lead to obesity. Contain a lot of fruits, vegetables, whole Cereal and fish dietCan reduce the risk of stroke.
Prevention of stroke 1: Improve lifestyle
The following measures can prevent stroke: (1) Quit smoking; (2) Exercise regularly and maintain a healthy weight; (3) Limit alcohol and salt intake Amount; (4) Eat a healthy diet, moreEat vegetables, fruits, and whole grains.
Prevention of stroke two: use of drugs
Doctors usually recommend drugs to reduce the risk of stroke patients.
- Antiplatelet drugs (including aspirin) prevent platelet aggregation in the blood and prevent blood clots.
- Antithrombotic drugs are effective for some patients.
- If you have high blood pressure, your doctor will prescribe some drugs to lower your blood pressure.
Prevention of stroke 3: Surgery
In some cases, stroke is caused by carotid artery stenosis. Carotid endarterectomy can treat small strokes caused by carotid artery stenosis. Surgery removes the plaque on the carotid artery and helps prevent stroke.
Prevention of Stroke IV: Stents
Patients with carotid artery obstruction can use angioplasty (temporarily placed in the carotid blood vessel A stent uses a miniature balloon to expand the space of the blood vessel), and the stent is placed to ensure that the artery opens.
