Stroke

Stroke is an acute cerebrovascular disease, a group of diseases that cause brain tissue damage due to sudden rupture of blood vessels in the brain or failure of blood flow to the brain due to vascular obstruction, including ischemic and hemorrhagic strokes. The incidence of ischemic stroke is higher than that of hemorrhagic stroke, accounting for 60% to 70% of all strokes. Occlusion and stenosis of the internal carotid artery and vertebral artery can cause ischemic stroke, which is more common in men than in women over the age of 40 and can cause death in severe cases. The mortality rate of hemorrhagic stroke is high. Surveys show that stroke has become the first cause of death in China in both urban and rural areas combined, and the leading cause of disability in Chinese adults. Stroke is characterized by high incidence, high mortality and high disability rates. Different types of stroke are treated in different ways. Because of the persistent lack of effective treatment, prevention is currently considered the best measure, with hypertension being an important controllable risk factor for stroke, and therefore antihypertensive treatment is particularly important to prevent stroke onset and recurrence. Education on stroke risk factors and aura symptoms should be strengthened to popularize stroke in the whole population in order to truly prevent and treat stroke.
