Mild hypertension, or hypertension grade 1, is diagnosed as a systolic blood pressure of 140 to 159 mmHg?and a diastolic blood pressure of 90 to 99 mmHg; how it is treated depends on whether there is clinical disease and risk factors. If there is no combination of clinical disease and risk factors, it is low risk and treatment is based on improving lifestyle. If there are risk factors or a combination of clinical disease, medication needs to be initiated. Lifestyle improvement includes regular rest, no late nights, relaxation, stress reduction, no smoking, no alcohol consumption, more exercise, and weight control. It is also important to pay attention to a proper diet, including consuming adequate amounts of fruits and vegetables and reducing salt intake. The Chinese Nutrition Society recommends that the daily sodium intake of healthy adults should not exceed 6 grams (6 grams of salt is only equivalent to the volume of a beer bottle cap), and no more than 3 grams for patients with hypertension. With the above lifestyle improvements, most patients can return to normal, and if they still cannot return to normal after six months, medication is required. If there are risk factors or combined clinical diseases, such as combined hyperlipidemia, diabetes, coronary heart disease, kidney disease, cerebrovascular disease, etc., or a history of smoking and family history of cardiovascular disease at the same time, drug therapy needs to be initiated along with improving poor lifestyle. Commonly used drugs include angiotensin-converting enzyme inhibitors, such as benazepril; angiotensin II receptor antagonists, such as valsartan; calcium channel blockers, such as amlodipine besylate and nifedipine controlled-release tablets; beta-adrenergic receptor antagonists, such as metoprolol succinate.
