A high pressure of 160 and a low pressure of 120, i.e., a systolic pressure of 160 mmHg and a diastolic pressure of 120 mmHg, is classified as Grade III hypertension, which is very serious. Grade 3 hypertension is defined as systolic blood pressure greater than or equal to 180 mmHg, and/or diastolic blood pressure greater than or equal to 110 mmHg. systolic blood pressure of 160 mmHg and diastolic blood pressure of 120 mmHg, which belongs to grade 3 hypertension, is severe hypertension and is very serious. Symptoms such as severe headache, vomiting, palpitations, vertigo, and in severe cases, confusion and convulsions may occur. Lifestyle intervention and medication are the fundamental treatments for hypertensive patients. It is necessary to maintain a low-salt and low-fat diet, eat fresh vegetables and fruits every day, reduce weight, increase exercise, quit smoking and drinking, reduce mental stress, and keep a balanced mind. Currently commonly used antihypertensive drugs can be summarized into five major categories, namely diuretics such as hydrochlorothiazide, beta receptor antagonists such as metoprolol tartrate, calcium channel blockers such as nifedipine, angiotensin-converting enzyme inhibitors (ACEIs) such as captopril and angiotensin II receptor antagonists (ARBs) such as chlorthalidomide. For patients with tertiary hypertension who require a combination of medications, a combination of three or more antihypertensive drugs in the appropriate dosage (which should generally include a diuretic), such as a combination of nifedipine, valsartan, and hydrochlorothiazide, may be used as prescribed by a physician. It is recommended that patients seek timely medical treatment, standardized treatment under the guidance of doctors, and not blindly use drugs on their own.
