There are many types of risk factors for ischemic stroke, but the following are common: (1) family history of stroke; (2) hypertension; (3) over 55 years of age; (4) smoking; (5) hypertension + smoking in women over 55 years of age; (6) heart disease (atrial fibrillation, coronary artery disease); (7) hypercholesterolemia (≥200 mg/dl); (8) diabetes mellitus; (9) sleep apnea (11) carotid plaque; (12) erythrocytosis; (13) positive CRP; (14) previous stroke, depression, etc. In this paper, the results of 343 cases of ischemic stroke risk factors were generally consistent with the findings. Zhang Guozhu, Department of Neurology, Second People’s Hospital of Chizhou, China 2. Risk factors are important factors for ischemic stroke 40% to 90% of stroke patients have hypertension, and patients with atrial fibrillation are more than 6 times more likely to have stroke than those without atrial fibrillation. About 15% of stroke patients have atrial fibrillation, and the incidence increases with age, with the most common being over 65 years of age, 6.7% of all strokes occurring in people aged 50-59 years, and 36.2% of strokes occurring in people aged 80-89 years. The key to preventing stroke is to intervene in the treatment of risk factors. The role of hypertension as a cause of stroke is obvious, and it is the most important independent risk factor for stroke among the many risk factors for stroke. In this paper, 128 out of 210 cases (60.7%) in the intervention group and 68 cases (51%) in the control group had hypertension, accounting for the first of all risk factors, so that active treatment of hypertension should be given high priority. Studies such as this one found that the risk of stroke is closely related to the level of hypertension, and the higher the blood pressure, the greater the risk of stroke. The incidence of stroke increases by 17% for every 2 mmHg increase in diastolic blood pressure, while the incidence of stroke decreases by 38% for every 10-12 mmHg decrease in systolic blood pressure and 5-6 mmHg decrease in diastolic blood pressure, due to the presence of damaged vascular endothelial cells, activated endothelial cells, activated platelets, activated leukocytes, elevated coagulation factors, and impaired fibrinolytic activity associated with thrombosis in hypertensive patients. Weinborger et al. showed that diastolic blood pressure decreases after the age of 50 years and systolic, pulse and mean arterial pressures increase with age. If left untreated, the increased systolic pressure can cause arterial stiffness. Systolic and diastolic blood pressure are considered to be the main indicators for diagnosing hypertension and evaluating its efficacy and impact on the human body, while pulse pressure is considered to be an independent risk factor for cardiovascular accidents in middle-aged and elderly people, and increased mean arterial pressure is a major risk factor for stroke. After measuring blood pressure at least once a week, we recorded the four components of blood pressure: systolic blood pressure, diastolic blood pressure, pulse pressure and mean arterial pressure, and adjusted the medication according to their changes to achieve satisfactory results. For those with blood pressure ≥ 140/90 mmHg are given antihypertensive treatment, according to blood pressure level, risk factors, efficacy, compliance and side effects to give a single or combination of drugs with long-acting antihypertensive effect, and as far as possible to take a long-acting antihypertensive preparations given once a day. For elderly simple systolic hypertension is generally used diuretics + ACEI, for hypertension combined with myocardial infarction more β blockers and ACEI, for elderly hypertension combined with coronary heart disease, a common patient also choose β receptor blockers, ACEI and long-acting calcium antagonists, for hypertension combined with diabetes preferred ACEI, it can make the risk of cardiovascular complications It can reduce the risk of cardiovascular complications by 25% to 30%, but try not to use β blockers, because it may have adverse effects on glucose metabolism. ACEI and calcium antagonists are usually used in hypertensive patients with mild to moderate renal insufficiency because they can reduce glomerular proliferation and fibrosis in addition to lowering blood pressure, thereby protecting the kidneys. In the intervention group, our treatment of patients with and without hypertension but with other risk factors began with lifestyle changes, including increasing aerobic activity for at least 30 min per day and learning to find ways to relax mental tension, abstaining from full meals and reducing intake of saturated fatty acids and salt, reducing weight in overweight individuals, quitting smoking, and limiting alcohol intake (15 to 15 minutes for high alcohol). The intake of alcohol (less than 15-20 ml/d of high alcohol), while maintaining the intake of potassium, usually eat more fruits, fresh vegetables and whole grains. High salt intake is associated with left ventricular hypertrophy and stroke, so for those with salty diets we remind them to make their tastes lighter as appropriate, and for those with familial hyperlipidemia or total cholesterol ≥5 mmol/L, those with significant atherosclerosis or intimal thickening or plaque in the large carotid arteries, and those with chronic atrial fibrillation are routinely given statins and receive aspirin 75 mg/d The treatment is often switched to bimatoprost or clopidogrel if contraindicated, and is often used to activate blood circulation in patients with abnormal blood flow indicators. Some people have studied that erythrocyte deformability and erythrocyte volume size are significantly and positively correlated with blood pressure, and Smith et al. found that blood viscosity and blood cell volume are correlated with blood pressure.
