A low blood pressure of 105 mmHg is mostly considered to be grade 2 hypertension, and if the systolic blood pressure is above 180 mmHg, it is grade 3 hypertension. Even if there are no symptoms, patients still need to follow the doctor’s instructions for medication and general measures according to their own conditions. 1. Medication: Usually, patients can use calcium antagonists such as nifedipine, levamlodipine, diltiazem and so on according to the doctor’s instruction. Angiotensin system inhibitors such as captopril and perindopril or angiotensin receptor antagonists such as irbesartan, candesartan and valsartan can also be used. Meanwhile, beta-blockers such as bisoprolol and metoprolol and diuretics such as furosemide and spironolactone also have antihypertensive effects. 2. General measures: patients usually need to develop good dietary habits, control potassium and sodium intake, and also need to ensure balanced nutritional intake. Patients also need to maintain good living habits, quit smoking and drinking in time, and pay more attention to emotional regulation, maintain an optimistic state of mind, which is helpful for the control of the disease. At the same time, patients also need to regularly monitor the blood pressure changes, if abnormal, but also need to consult a doctor.
