Blood pressure 170/100 if a clear diagnosis of hypertension can be made, any one or more of the five classes of antihypertensive drugs can be taken, but the exact medication depends on the patient’s condition. Patients with a blood pressure of 170/100mmHg should have their blood pressure levels monitored repeatedly, and a diagnosis of hypertension can be made if the blood pressure level exceeds 140/90mmHg three times on non-same days, and 170/100mmHg meets the criteria for hypertension II. Patients initially diagnosed with hypertension, if it is hypertension grade I or grade II, can temporarily control their blood pressure levels through lifestyle modifications, such as controlling salt, low-fat diet, maintaining a happy mood, ensuring adequate sleep, and also adhering to physical exercise. Hypertensive patients with ineffective lifestyle adjustments can take oral calcium antagonist amlodipine, angiotensin-converting enzyme inhibitor captopril, angiotensin II receptor antagonist valsartan, beta-blocker metoprolol, diuretic hydrochlorothiazide, and so on, and the appropriate medication should be selected according to the characteristics of the patient’s condition. Generally, one antihypertensive drug is chosen first, and if it is not effective, it can be used in combination. Hypertension level 2, if combined with cardiovascular and cerebrovascular diseases, belongs to high-risk patients, and should be immediately given antihypertensive treatment on the basis of lifestyle adjustment. Patients with hypertension should choose the appropriate medication under the guidance of a physician and monitor blood pressure levels.
