Patients with grade 1 hypertension with no amount of comorbidities do not need medication, and patients with more risk factors can take antihypertensive drugs such as valsartan. 1.Grade 1 hypertension refers to the systolic blood pressure of 140-159mmHg and/or diastolic blood pressure of 90-99mmHg without taking antihypertensive drugs. If there is no combination of cardiovascular, cerebral vascular, hyperglycemia, hyperlipidemia and other diseases, there is no need to intervene with medicines for the time being, and blood pressure can be lowered by reducing body weight, sodium salt intake, fat intake, and increasing exercise. 2. If grade 1 hypertension is combined with cardiovascular, cerebrovascular, hyperglycemia, hyperlipidemia and other diseases, or if there is already damage to target organs such as the heart, brain, kidney, etc., in order to avoid the emergence of serious complications, medication can be used, and the first-line antihypertensive drugs commonly used in clinical practice are valsartan, nifedipine, captopril and so on. Grade 1 hypertensive patients should pay close attention to blood pressure changes and take timely interventions to prevent deterioration of the condition. If blood pressure rises, they should go to the hospital in time and take antihypertensive drugs as prescribed by the doctor, do not take drugs and change drugs without authorization.
