The normal value of blood pressure at the age of 48 is related to whether or not it is combined with other diseases. The normal value of blood pressure without combining other diseases is lower than 140/90mmHg, and the target value of blood pressure control for patients with combined diabetes mellitus, coronary artery disease, heart failure, and chronic kidney disease should be lower than 130/80mmHg. 1. Hypertension is related to genetic factors, environmental factors (e.g. diet, smoking, mental, etc.) and factors such as body weight, medication, respiratory sleep apnea, etc. Reducing body weight, decreasing sodium intake, supplementing potassium salt, decreasing fat intake, quitting smoking and limiting alcohol consumption, exercising appropriately, and decreasing mental stress play a positive role in controlling blood pressure. 2. Patients with hypertension grade 2 or above (systolic blood pressure ≥160mmHg and/or diastolic blood pressure ≥100mmH), patients with hypertension combined with diabetes mellitus or patients with complications, and patients with unsatisfactory effect of lifestyle improvement should be given drug treatment. 3. There are five major classes of drugs commonly used in the treatment of hypertension: diuretics (e.g. furosemide, spironolactone, hydrochlorothiazide, etc.), beta-blockers (e.g. bisoprolol, metoprolol, etc.), calcium channel blockers (e.g. nifedipine, verapamil, etc.), ACEIs (e.g. captopril, enalapril, etc.), and ARBs (e.g. valsartan, etc.). Hypertension is the most important risk factor for cardiovascular and cerebrovascular diseases, which can cause damage to the heart, brain, kidney, retina and other important organs. Early prevention and treatment of hypertension is of great significance, and the discovery of hypertension should be diagnosed and treated in regular hospitals as soon as possible to avoid delays.
