There are certain criteria for when to apply medication to patients with hypertension. If the blood pressure is measured for the first time and is above grade 2 hypertension, that is, blood pressure greater than 160/100 mmHg, then prompt oral antihypertensive medication is required. Some patients with hypertension are found to have hypertension for the first time, but it is obviously caused by metabolic syndrome. In this case, therapeutic lifestyle intervention can be appropriate, and if the blood pressure cannot be effectively controlled after therapeutic lifestyle intervention, timely antihypertensive medication is also required. Therapeutic lifestyle interventions include strict weight control, control of sodium and fat intake, as well as increasing exercise and reducing mental stress. Some patients with hypertension may have combined diabetes or coronary artery disease, cerebral infarction, or renal insufficiency. In this case, regardless of the blood pressure value, it is necessary to apply antihypertensive drugs in a timely manner for control.
