Cerebrovascular disease (cerebralvasculardiseases), broadly refers to various diseases of the blood vessels of the brain, including cerebral artery atherosclerosis, thrombosis, stenosis, occlusion, cerebral arteritis, cerebral artery injury, cerebral aneurysm, intracranial vascular malformation, cerebral arteriovenous fistula, etc. The common feature is to cause ischemic or hemorrhagic accidents of brain tissue, leading to disability or death of patients, and the incidence accounts for The incidence accounts for 1/4 to 1/2 of total neurological hospitalizations. What are the triggering factors of cerebrovascular disease? 1, anger, exertion, excessive force, mental factors, climate change, cervical spondylosis and discontinuation of antihypertensive drugs, the above triggering factors are closely related to the patient’s age, the nature of work, especially fluctuations in blood pressure or changes in the blood supply to the brain. 2, age: middle-aged and old people are prone to cerebrovascular disease. 3, exertion and mental factors: emotional excitement and excessive fatigue can increase blood pressure, changes in blood viscosity, resulting in the rupture or injury of the weak point of the blood vessels and even cause cerebral hemorrhage or cerebral thrombosis. 4, seasonal changes: the stimulation of the external environment such as cold or heat makes the patient’s blood viscosity change. Therefore, elderly people who suffer from cerebral atherosclerosis, hypertension, cervical spondylosis and heart disease should pay attention to eliminate and avoid the above factors in time. The effect of hypertension on cerebrovascular disease? 1, long-term sustained elevation of blood pressure will not only increase the pressure in the blood vessels, but also cause the formation of a kind of chestnut-sized aneurysm in the small arteries of cerebral atherosclerosis, so when some reason induces an increase in blood pressure in the body, the aneurysm may rupture and cause cerebral hemorrhage. 2. Hypertension can also cause spasm of small arteries in the brain and hypoxic necrosis of brain tissue causing punctate hemorrhage and cerebral edema. 3. Hypertension can also cause changes in the endothelial structure of cerebral blood vessels, resulting in changes in the permeability of the vessel wall, impairment of the coagulation mechanism, thickening of the intima, and narrowing of the vessel wall leading to insufficient blood supply. What are the effects of smoking on cerebrovascular disease? Smoking excites sympathetic nerves, increases the release of epinephrine and norepinephrine, leads to increased blood pressure, acts directly on the arterial wall, causing steatosis, increases platelet aggregation and adhesion, reduces the barrier function of vascular endothelial cells, causes platelet aggregation and leads to arterial thromboembolism, increases dense lipoprotein cholesterol and lowers high-density lipoprotein cholesterol.
