Cerebral infarction, formerly known as cerebral infarction, also known as ischemic stroke (cerebral ischemic
stroke), refers to ischemic necrosis or softening of restricted brain tissue caused by impaired blood supply to the brain, ischemia and hypoxia. The common clinical types of cerebral infarction are cerebral thrombosis, lacunar infarction and cerebral embolism, and cerebral infarction accounts for 80% of all strokes. Diseases closely related to it include diabetes, obesity, hypertension, rheumatic heart disease, arrhythmia, dehydration of various causes, various arteritis, shock, and too rapid and too large a drop in blood pressure. Clinical manifestations are characterized by sudden fainting, unconsciousness, hemiplegia, speech impairment, and mental retardation. Cerebral infarction not only poses a great threat to human health and life, but also brings great pain and heavy burden to patients, families and society. What are the high-risk factors of cerebral infarction? 1.Smoking and alcohol consumption. According to the survey, more than half of the patients with cerebral infarction have a long-term history of smoking and alcohol consumption. Therefore, smoking and alcohol consumption are important causes of cerebral infarction in the elderly. Smoking can cause the lipid and fibrinogen content in the blood to rise, resulting in higher blood viscosity, and smoking and drinking can accelerate atherosclerosis. After drinking alcohol, the content of alcohol in the blood increases rapidly. Alcohol has the effect of constriction and spasm of cerebral blood vessels. Therefore, alcohol consumption can increase the incidence of cerebral infarction. Therefore, elderly people should quit smoking and alcohol or limit the intake of alcohol as soon as possible. 2. Hypertension. According to statistics, more than half of the elderly have different degrees of hypertension. The incidence of cerebral infarction is 7 times higher in hypertensive patients than in those with normal blood pressure. Controlling blood pressure at a normal level can effectively reduce the incidence of cerebral infarction. With the development of medical technology, it is possible to control blood pressure to a normal level by using a close combination of pharmacological and non-pharmacological treatments. Therefore, patients with hypertension should actively control their blood pressure to prevent the occurrence of cerebral infarction. 3. Diabetes. Diabetic patients have a significantly higher chance of developing atherosclerosis than normal people. Therefore, diabetes is also an important risk factor for the occurrence of cerebral infarction in the elderly. Therefore, elderly people should have at least two blood glucose checks each year in order to detect and treat diabetes early and reduce the incidence of cerebral infarction. 4.Higher blood lipids. Most of the obese elderly people have elevated blood lipids. Increased blood lipids are the main risk factor for atherosclerosis. Atherosclerosis is the direct cause of cerebral infarction in the elderly. Therefore, elderly people who are fat should actively reduce their body weight and regulate lipid metabolism through comprehensive measures such as diet, exercise and drug therapy to prevent cerebral infarction. 5.
