What causes cerebral infarction? What are the causes of cerebral infarction?

1. Vascular lesions:

Atherosclerosis of blood vessel wall lesions (about 70% of patients with cerebrovascular disease), arteritis (rheumatism, tuberculosis, etc.), congenital anomalies (aneurysms, vascular malformations, etc.), trauma, poisoning, tumors, etc.;

2. Blood lesions:

Increased blood viscosity. Such as hyperlipidemia, hyperglycemia, hyperproteinemia, dehydration, polycythemia, leukemia, thrombocythemia, etc.;

Abnormal coagulation mechanisms. Such as thrombocytopenic purpura, hemophilia, use of anticoagulants, diffuse intravascular coagulation, etc. In addition, pregnancy, postpartum, surgery, and taking contraceptive pills can cause coagulability;

3. Hemodynamic changes.

Such as hypertension (about 55%-75% of non-embolic cerebrovascular disease), hypotension, cardiac dysfunction (heart failure, coronary heart disease, atrial fibrillation, conduction block), etc.;

4. Miscellaneous. The influence of extravascular factors is mainly the compression of lesions adjacent to large blood vessels (such as cervical spondylosis, tumors, etc.), which affects the insufficiency of blood supply;

Various emboli formed outside the skull, etc.

It is mainly caused by cerebral atherosclerosis and narrowing of the lumen: 1. Endothelial cells of the blood vessel wall are damaged due to hypertension, increased catechol ammonia, hypercholesterolemia, etc.; 2. Arterial wall fibrosis, calcification, ulcer, etc.; 3. Blood pressure drops, slow blood flow and other reasons, such as: night sleep, cardiac insufficiency and low blood pressure.

There are many kinds of ** that can lead to cerebral infarction in patients, for example, if patients smoke and drink for a long time, it is easy to lead to damage to the vascular endothelium, and these patients will have atherosclerosis of the arteries, resulting in obstruction and stenosis of blood vessels in the skull.

If the patient has hypertension, diabetes, hyperlipidemia, hyperhomocysteinemia, it is also easy for the patient to develop atherosclerosis.

In addition, if the patient has congenital vascular stenosis, or if the patient has an immune system disease such as vasculitis, these patients are prone to sediment in the blood vessels in the skull, resulting in obstruction of the blood vessels, and the patient will also have cerebral infarction.

If the patient has atrial fibrillation, the embolus may also fall off and cause cerebral infarction.

The main causes of cerebral infarction are atherosclerosis and hypertension. Atherosclerosis and plaque detachment can cause cerebral infarction. It can be used orally to invigorate blood circulation, reduce lipids, stabilize spots, and improve microcirculation.

Drink plenty of water, eat plenty of vegetables and fruits, and actively participate in outdoor sports.
