The diagnostic criteria for hypertension are: systolic blood pressure greater than or equal to 140 mmHg or/and diastolic blood pressure greater than or equal to 90 mmHg obtained from three or more measurements in a quiet state, not on the same day, can be diagnosed as hypertension. The main aspects of treatment are as follows: 1. Dietary control, including low salt intake (less than 6 grams of total salt intake per day), and appropriate intake of foods and fruits rich in potassium and calcium ions, such as bananas and fresh vegetables, are recommended. Avoid greasy foods (containing too much saturated fatty acids). 2, weight control, for overweight or obese people, it is recommended to control weight within the normal range (BMI18-24) through aerobic exercise (it is recommended that aerobic exercise of moderate physical activity such as jogging, cycling, swimming, etc. at least 3 times a week, lasting more than 30 minutes each time). 3, reduce work pressure, regulate emotions. Because of long-term high stress state, the sympathetic nerves in the body overexcited, will cause vasoconstriction resulting in increased blood pressure. 4, quit smoking, limit alcohol. Tobacco contains excessive substances that contribute to the formation of atherosclerosis, such as nicotine, nitrogen oxides, etc. Excessive alcohol intake is harmful to cardiomyocytes and can even cause alcoholic cardiomyopathy in severe cases. 5, drug therapy: including calcium antagonists, ACEI/ARB, diuretics, beta-blockers, etc.. They are common blood pressure control drugs, each through a different mechanism to achieve the purpose of lowering blood pressure. For patients with combined diabetes, hyperlipidemia, coronary heart disease, etc., there are also differences in the selection. For example, in patients with hypertension combined with diabetes and normal renal function, ACEI/ARB drugs are preferred. 6, treatment of blood glucose, dyslipidemia, sleep apnea, etc. Patients with hypertension are often combined with other cardiovascular and cerebrovascular high-risk factors or diseases, so they need comprehensive treatment and cannot lose sight of each other. Pay attention to hypertension, scientific understanding of hypertension, reduce the occurrence of cardiovascular and cerebrovascular complications, and improve the quality of life.
