Hypertension, whether hemorrhagic stroke or ischemic stroke, is the most important independent risk factor. Through antihypertensive drugs and low-salt diet, blood pressure gradually dropped below 140/90mmHg.

2, diabetes, by controlling diet and hypoglycemic drugs, the blood sugar is reduced to the normal range of 3.9-6.1mmol/L.

3, heart disease, such as rheumatic heart disease, coronary heart disease. In particular to prevent cerebral embolism caused by embolic shedding caused by atrial fibrillation.

4, dyslipidemia, very low density lipoprotein, low density lipoprotein is the most important lipoprotein that causes atherosclerosis, and high density lipoprotein is anti-atherosclerosis lipoprotein.

5, transient ischemic attack (TIA), TIA itself is a classification of ischemic stroke, can also be a precursor or precursor of cerebral infarction, should be treated in time.

6. Smoking and drinking;

7. When the hemorheology is disordered, especially when the whole blood viscosity is increased, the cerebral blood flow decreases, and the increase of hematocrit and fibrinogen level are the main risk factors of ischemic stroke;

8. Obesity, obesity and overweight are all risk factors of ischemic stroke, and have nothing to do with hemorrhagic stroke.

9. Age, sex and age are important risk factors for atherosclerosis, and the degree of atherosclerosis increases with age. Over 50 years old, the incidence of stroke also increases with age, but the author found that the incidence of stroke in young and middle-aged people has also increased, which can not be ignored. Generally speaking, the incidence of stroke in women is lower than that in men.
