"Stroke" everyone should have heard of in daily life, it does not mean that it is simply blown by the wind so simple, its clinical name is actually "stroke", which is an acute cerebrovascular disease, but also one of the biggest factors in the death of mainland residents due to disease!
In mainland clinical practice, stroke is mainly divided into two main types:
The first is the hemorrhagic stroke caused by the sudden rupture of cerebral blood vessels and hemorrhage, which is commonly known as cerebral hemorrhage.
The second category is the cerebral tissue blood supply due to excessive narrowing and blockage of cerebral blood vessels, and injury diseases, which are called ischemic stroke in the clinic, which is commonly known as cerebral infarction!
According to the current data, the incidence of cerebral infarction in mainland China is significantly higher than that of cerebral hemorrhage, which accounts for about 60 to 70% of all stroke patients.
However, no matter which kind of stroke disease, it has the characteristics of acute onset, extremely high disability, certain fatality rate, and certain recurrence rate.
Moreover, due to the lack of effective clinical treatment, even if patients save their lives, they will leave certain sequelae, so it is currently believed that prevention is the best measure.
Although the onset of stroke is unexpected, in fact, the cause of stroke has long existed. Controlling the risk factors for stroke is the best way to prevent stroke.
So the question is, what are the reasons related to the onset of stroke?
1. Hyperlipidemia: its full name in the clinic is hyperlipoproteinemia, that is, the patient's blood lipid level exceeds the normal standard, which is the most common form of dyslipidemia.
Hyperlipidemia seems to have no symptoms, but its damage to the body is insidious, gradual, progressive and systemic, and its direct damage is to accelerate the formation of atherosclerosis throughout the body;
Once the arteries that supply blood to the brain tissue gradually harden and there is a blockage of atherosite plaques, it may lead to the occurrence of stroke;
2. Hypertension: Hypertension seems to be only characterized by an increase in arterial blood pressure, and patients may not have any symptoms, but this does not mean that it is not damaged.
Hypertension that cannot be effectively controlled will not only cause spasm of fine arterioles throughout the body, but also gradually harden the fine arteries, and the lipid deposition of the lining of the mediated and large arteries will form atherosclerosis and thrombosis.
Not only that, but high blood pressure can also cause aneurysms, which are a high-risk factor for cerebral hemorrhage. Because of this, hypertension is seen as the most important independent risk factor for stroke;
3, diabetes: although diabetes is characterized by elevated blood sugar, it is more worrying, in fact, it is a variety of complications caused by the development of high blood sugar.
Studies have shown that 20 to 40% of patients with type 2 diabetes will have cerebrovascular disease.
Because diabetes can cause intracranial large blood vessels and microangiopathy, patients will develop atherosclerosis in the initial stage, and then may be complicated by cerebral hemorrhage, cerebral infarction, brain atrophy and other problems on this basis, which is the most important factor in the death of diabetic patients;
4. Atherosclerosis: In addition to the three factors mentioned above, atherosclerosis can be caused, genetic genes, smoking and alcoholism, obesity, etc., will also accelerate the formation of atherosclerosis through a variety of mechanisms.
Atherosclerosis starts from the intima, generally first there are lipids, complex sugar aggregation, bleeding and thrombosis, and then gradually develop into fibrous tissue hyperplasia and calcium sedimentation, thickening of arterial walls, narrowing of vascular lumen, and eventually causing the onset of cerebral infarction;
5, the blood viscosity is too high: the pace of modern people's life is very fast, family and work pressure is relatively large, and the mood is becoming more and more unstable.
Affected by the increase in diet level, the reduction in exercise and other aspects, it will lead to a decrease in the rate of metabolism in the human body, a slowdown in blood circulation, and an increase in blood viscosity, laying the foundation for atherosclerosis, and then increasing the prevalence of later stages.
In a word, from healthy blood vessels to atherosclerosis, from blood vessel stenosis to stroke attacks, it takes quite a long time, even years, decades.
Therefore, although the onset of stroke is sudden, it has already laid the foundation for it before. In the future, if you don't want to find a stroke, it is necessary to stay away from bad habits and control the development of the primary disease from now on.
