Cerebral infarction is a serious cerebrovascular disease, and its full name is "cerebral infarction", also known as ischemic stroke. It refers to the blockage of blood vessels in the brain, resulting in insufficient blood in the brain, causing necrosis of brain cells and atrophy of brain tissue, thereby triggering a series of neurological deficit symptoms.
The causes of cerebral infarction are varied, the most common of which is atherosclerosis, in which plaques break off and block blood vessels, causing cerebral infarction. In addition, cardiogenic emboli, Takayasu's arteritis, hematologic diseases, and moyamoya disease are also common causes of cerebral infarction.
The symptoms of cerebral infarction are also varied, depending on the location and extent of the infarction. Common symptoms include hemiplegia, aphasia, dizziness, nausea, vomiting, difficulty swallowing, impaired consciousness, etc. In the early stages of cerebral infarction, these symptoms are usually mild, but they gradually worsen as the disease progresses.
For cerebral infarction, drugs are generally included and drugs are mainly used to improve cerebral blood circulation and prevent thrombosis through thrombolysis, anticoagulation, antiplatelet aggregation and other drugs. **It is mainly through physical **, homework ** and other means to promote the recovery of patient function.
There is no direct causal relationship between blood pressure and the occurrence of cerebral infarction. However, long-term high blood pressure can increase the risk of cerebral infarction. When the blood pressure exceeds 140 90mmHg, it is considered hypertension.
High blood pressure can lead to cerebral vasospasm and reduced blood flow to the brain, which can lead to cerebral infarction. In addition, high blood pressure can also accelerate the process of atherosclerosis, narrowing or occluding cerebral blood vessels, further increasing the risk of cerebral infarction.
However, even if the blood pressure is high to a certain level, it does not necessarily cause an immediate cerebral infarction. The occurrence of cerebral infarction is also affected by other factors, such as age, gender, genetics, environment, etc. In addition, the presence of other risk factors, such as smoking, alcoholism, obesity, etc., will also affect the occurrence of cerebral infarction.
Therefore, there is no definitive answer to how high blood pressure can cause a cerebral infarction. However, in order to reduce the risk of cerebral infarction, we should actively control blood pressure. If the blood pressure exceeds 140 90mmHg, you should seek medical attention and receive **.
Blood pressure 145 95 in the case of cerebral infarction, this does not mean that a blood pressure of 160 100 is necessarily safe, in fact, blood pressure is only a factor in the occurrence of cerebral infarction, not a decisive factor.
The mechanism of cerebral infarction is usually due to the rupture of plaques in the walls of blood vessels, resulting in blockage of blood vessels, resulting in insufficient blood supply to the brain. High blood pressure, hyperlipidemia, diabetes, smoking, obesity, etc. are all risk factors for cerebral infarction. In addition, genetic factors, psychological stress, lack of exercise, etc. are also related to the occurrence of cerebral infarction.
For blood pressure 145 95 cerebral infarction, it may be due to individual differences, blood vessel quality, blood viscosity and other factors.
And 160 out of 100 people are fine, probably because their blood vessels are of better quality, or their blood is less viscous and is able to pump blood better.
In addition, individual differences are also important factors affecting the occurrence of cerebral infarction. Some people may be more sensitive to fluctuations in blood pressure, while others may be more tolerant. This also explains why, at the same blood pressure level, some people develop cerebral infarction, while others do not.
Dizziness: Before the onset of cerebral infarction, patients may experience persistent symptoms of dizziness. This type of dizziness is different from ordinary dizziness, and it may be accompanied by symptoms such as nausea, vomiting, and imbalance disorders. This can be caused by a lack of blood supply to the brain and requires prompt medical attention.
Blurred vision: Blurred vision is also one of the common signals that precede a cerebral infarction. Patients may experience decreased vision, narrowed visual fields, or black spots in front of their eyes. This can be caused by retinal ischemia and requires prompt medical examination.
Slurred speech: Before the onset of cerebral infarction, patients may experience symptoms such as slurred speech, aphasia or difficulty speaking. This may be caused by insufficient blood supply to the language center of the brain and requires prompt medical examination.
Limb numbness: Before a cerebral infarction, patients may experience symptoms such as numbness, weakness, or pain in the limbs. This can be caused by a lack of blood supply to the brain and requires prompt medical examination.
First of all, the prevention of cerebral infarction needs to start with daily life Xi. In terms of diet, you should maintain a low-salt, low-fat, and low-sugar diet Xi and eat more foods rich in dietary fiber, such as vegetables, fruits, whole grains, etc. At the same time, it is necessary to avoid excessive alcohol consumption and smoking, which can cause damage to blood vessels.
Secondly, maintaining appropriate exercise is also an important measure to prevent cerebral infarction. Moderate aerobic exercise can enhance cardiopulmonary function, improve blood circulation, and reduce the risk of cerebral infarction.
In addition, controlling blood pressure and blood sugar is also key to preventing cerebral infarction. Hypertension and hyperglycemia are important factors leading to cerebrovascular diseases, so it is necessary to monitor blood pressure and blood sugar regularly and take corresponding measures in time.
Finally, for patients who have already suffered from cerebral infarction, it is also very important to be timely and **. In the acute phase, patients need to undergo emergency measures such as thrombolysis and thrombectomy to restore blood to the brain**.
In the first stage, patients need to undergo targeted training, such as language, limb function training, etc., to restore their ability to take care of themselves.
