For example, a patient with cerebrovascular disease comes to acupuncture treatment with the smell of cigarette smoke, although the immediate treatment of the disease is very positive, but do not know that smoking itself is an important risk factor for cerebrovascular disease, do not quit smoking, then how many times the acupuncture can not prevent the recurrence of stroke, and the hard work is wasted. The hard work is also in vain. So, what are the common risk factors for stroke? First, we need to clarify the risk factors into two types of modifiable and non-modifiable: Non-modifiable risk factors: (a) Age: 1.4-1.6 times higher in the 75+ group than in the 65-74 group (b) Sex: male > female, 1.3:1-1.7:1 (c) Race and Ethnicity: black > white, Han Chinese > other ethnic groups These risk factors, such as age, cannot be interfered with by humans, and as age increases, the chance of stroke just increases. (a) Hypertension: The risk of stroke is proportional to the increase in blood pressure. The incidence of stroke is much lower in those with stable blood pressure than in those with fluctuating diurnal blood pressure. Systolic hypertension alone is also a risk factor and deserves attention. (b) Heart disease: There is a clear relationship between the occurrence of ischemic stroke, such as atrial fibrillation: 7-30% of strokes over 60 years of age are caused by atrial fibrillation, and coronary heart disease: 0.7-3.2% of patients have a stroke within two weeks after an acute heart attack. This should be noted. (ii) Left ventricular hypertrophy: 4-fold increase in stroke risk in men and 6-fold increase in women. (iii) Diabetes mellitus: 1.8 times more prevalent in men and 2.2 times more prevalent in women who are non-diabetic. Even if clinical diabetes cannot be diagnosed, maintaining blood glucose in the high boundary of the normal range is an important factor in stroke. (iv) Smoking: For both men and women of all ages, smoking is a significant independent factor in the incidence of stroke, and the risk of stroke increases with the amount of smoking per day. (v) Alcohol: Alcohol consumption is an important potential risk for elevated blood pressure and increased prevalence of hypertension. (vi) Other factors: homocysteine levels, obesity, migraine, oral contraceptives, snoring. With the above risk factors in hand, you have the signposts to avoid stroke. For example, active blood pressure control, smoking and alcohol cessation, blood sugar control, etc., so to speak, none of them should be missing.
