Risk factors for cerebrovascular disease include: 1. Hypertension: It is recognized as the most important independent risk factor for cerebrovascular disease. The higher the blood pressure, the greater the risk of stroke. The risk of stroke in people with hypertension is three to six times higher than in normal people. 2, diabetes: diabetes is also the most common independent risk factor for cerebrovascular disease. The risk of ischemic cerebrovascular disease in diabetic patients is 2-3 times higher than that in the general population. Moderate exercise is important for the control of blood sugar. 3, hyperlipidemia: is an important risk factor for cerebrovascular disease. Hyperlipidemia leads to narrowing of the arterial lumen. 4, heart disease: all kinds of heart disease, such as atrial fibrillation, acute myocardial infarction, etc. can cause cerebrovascular disease. Timely treatment of heart disease can reduce the incidence of cerebrovascular disease. 5, transient ischemic attack (TIA): both a cerebrovascular disease and a risk factor. 30% of patients with cerebral infarction had a history of TIA before the onset, and 33% of TIA patients have to develop or reoccur complete stroke sooner or later. 6. Carotid stenosis: It is a potential risk factor for cerebrovascular disease. Ischemic cerebrovascular disease can occur when the degree of stenosis increases or when hemodynamic changes occur. 7. History of cerebrovascular disease: The recurrence rate of those who have had cerebrovascular disease is significantly higher. 8, smoking: smoking is the most preventable risk factor. Smoking can lead to cerebrovascular disease risk is proportional to the amount of smoking, up to 6 times greater than the non-smoking population. 9, alcohol abuse: also the most easily preventable risk factors. Long-term heavy drinking can cause cerebral atherosclerosis or carotid atherosclerosis, which can eventually lead to cerebrovascular disease. 10, obesity: obesity is also an important factor leading to the occurrence of cardiovascular and cerebrovascular disease, is also one of the important factors that significantly increase the death rate than the normal population.
