There is a small embolus on the inner wall of the blood supply vessel in the brain, which falls off and leads to arterial-arterial embolism, that is, ischemic stroke.
Caused by cerebrovascular or thrombotic bleeding, it is a hemorrhagic stroke.
The heart valve of patients with coronary heart disease and atrial fibrillation is prone to mural thrombus, which can block the cerebral vessels after the embolus falls off, leading to ischemic stroke.
Hypertension, diabetes, hyperlipidemia.
Smoking, unhealthy diet, obesity, lack of moderate exercise, excessive drinking and high homocysteine.
Stroke is also called stroke and cerebrovascular accident. It is an acute cerebrovascular disease, which is a group of diseases caused by the sudden rupture or blockage of blood vessels in the brain, which prevents blood from flowing into the brain.
Stroke includes ischemic stroke and hemorrhagic stroke. The incidence of ischemic stroke is higher than that of hemorrhagic stroke, accounting for 60% ~ 70% of the total number of strokes. Occlusion and stenosis of internal carotid artery and vertebral artery can cause ischemic stroke, mostly over 40 years old, more men than women, and even death in severe cases. Hemorrhagic stroke has a high mortality rate.
Stroke in urban and rural areas has become the first cause of death in China, and it is also the primary cause of disability for adults in China. Stroke has the characteristics of high incidence, high mortality and high disability rate.
Due to the lack of effective treatment, prevention is considered to be the best measure at present, and hypertension is an important controllable risk factor leading to stroke. Therefore, antihypertensive therapy is particularly important to prevent the onset and recurrence of stroke. We should strengthen the education of risk factors and premonitory symptoms of stroke, so as to truly prevent and treat stroke.
