With the development of modern society and the improvement of living standards, the incidence of cerebrovascular disease has increased, cerebrovascular disease has brought great harm to patients’ bodies and families, what are the factors that can lead to cerebrovascular disease? The so-called high-risk factors of cerebrovascular disease, is a close causal relationship with the occurrence of cerebrovascular disease factors, common as follows: 1, hypertension hypertension is the most important risk factors for cerebral hemorrhage and cerebral infarction. A domestic study showed that for every 10 mmHg increase in systolic blood pressure, the relative risk of stroke increased by 49%, and for every 5 mmHg increase in diastolic blood pressure, the relative risk of stroke increased by 46% after controlling other risk factors. A randomized controlled clinical trial of systolic hypertension in elderly Chinese showed a 58% reduction in stroke mortality in the antihypertensive treatment group compared with the placebo control group after 4 years of follow-up. 2. Heart disease The risk of stroke is more than 2 times higher in people with heart disease than in those without heart disease. Patients with non-valvular atrial fibrillation have an annual risk of stroke of 3% to 5%, accounting for about 50% of thromboembolic strokes. 3. Diabetes is an important risk factor for cerebrovascular disease. Patients with type II diabetes have a 2-fold increased risk of stroke. 4, dyslipidemia A large number of studies have confirmed that elevated serum total cholesterol (TC), low-density lipoprotein (LDL) and reduced high-density lipoprotein (HDL) are closely related to cardiovascular disease. 5, smoking Regular smoking is a recognized risk factor for ischemic stroke. Its pathophysiological effect on the body is multifaceted, mainly affecting the systemic vascular and blood system such as: accelerating atherosclerosis, increasing the level of fibrinogen, promoting platelet aggregation, lowering HDL levels, etc.. Long-term passive smoking may also increase the risk of stroke. 6. Alcohol consumption Evidence from population studies has shown that alcohol intake has a direct dose-related effect on hemorrhagic stroke. However, the relevance for ischemic stroke is still controversial. 7, carotid artery stenosis Some foreign studies found that 7% to 10% of men and 5% to 7% of women aged 65 years or older had carotid artery stenosis greater than 50%. In recent years, several large studies have shown that abdominal obesity is more closely related to stroke than increased body mass index (BMI) or homogeneous obesity. 9. Other risk factors: hyperhomocysteinemia; metabolic syndrome; lack of physical activity; unreasonable diet and nutrition; oral contraceptives; procoagulant risk factors.
