Generally divided into three levels:

First-level hypertension, systolic blood pressure is between 140mmHg and 159mmHg, and diastolic blood pressure is between 90mmHg and 99mmHg.

Secondary hypertension is between 160mmHg and 179mmHg. Diastolic blood pressure is between 100mmHg and 109mmHg.

Grade 3 or above hypertension means systolic blood pressure greater than 180mmHg and diastolic blood pressure greater than 110mmHg. Therefore, clinically, patients are expected to have an ideal blood pressure, which is around 120/80mmHg.

(1) Essential hypertension Treatment

1 , Treatment purposes and principles

The main goal of hypertension treatment is to reach the blood pressure standard, and the ultimate goal of antihypertensive treatment is to minimize the incidence and mortality of cardiovascular and cerebrovascular diseases in patients with hypertension. Antihypertensive treatment should establish blood pressure control target values. On the other hand, hypertension often coexists with other risk factors for cardiovascular and cerebrovascular diseases

(1) Improve life behaviors? ① Reduce and control weight. ②Reduce sodium intake. ③Supplement calcium and potassium salts. ④Reduce fat intake. ⑤ Increase exercise. ⑥Stop smoking and limit drinking. ⑦ Reduce mental stress and maintain psychological balance.

(2) Individualization of blood pressure control standards? Due to different causes and different pathogenesis of hypertension, clinical medications should be treated separately, and the most appropriate drugs and dosages should be selected to obtain the best curative effect.

(3) Collaborative control of multiple cardiovascular risk factors? Although blood pressure is controlled within the normal range after antihypertensive treatment, multiple risk factors other than elevated blood pressure still have an important impact on prognosis.

2. Antihypertensive drug treatment

For patients with detected hypertension, recommended antihypertensive drugs for initial and maintenance treatment should be used, especially once daily. Drugs that can control the disease for 24 hours and reach the target should follow four principles, namely starting with a small dose, giving priority to long-acting preparations, combined medication and individualization.

(1) Types of antihypertensive drugs? ① Diuretics. ②β-blockers. ③Calcium channel blockers. ④Angiotensin-converting enzyme inhibitors. ⑤Angiotensin II receptor blockers.

Single drug or combined drug should be selected based on the patient's risk factors, target organ damage and combined clinical diseases. The principles for selecting antihypertensive drugs are as follows:

1) Use blood pressure drugs with a half-life of 24 hours or more that can control blood pressure for 24 hours when taken once a day, such as amlodipine, to avoid complications caused by improper selection of treatment options. Iatrogenic early morning blood pressure is poorly controlled;

2) Use drugs that are safe, long-lasting and capable of controlling blood pressure every 24 hours to improve patients' treatment compliance;

3 ) Use drugs that have sufficient clinical trial evidence of cardio-cerebral benefits and can truly reduce long-term cardiovascular and cerebrovascular events to reduce cardiovascular and cerebrovascular events and improve the quality of life of patients with hypertension.

(2) Treatment options? Most patients without complications or comorbidities can use thiazide diuretics, β-blockers, etc. alone or in combination. Treatment should start with a low dose and gradually increase the dose.

In actual clinical use, the patient's cardiovascular risk factors, target organ damage, complications, comorbidities, antihypertensive efficacy, adverse reactions, etc. will all affect the choice of antihypertensive drugs.

(2) Treatment of secondary hypertension

It is mainly aimed at the treatment of the primary disease, such as hypertension caused by pheochromocytoma. After tumor resection, the blood pressure can be reduced to Normal; renovascular hypertension can be treated with interventional therapy to dilate the renal arteries. For those whose primary disease cannot be cured by surgery or whose blood pressure remains high after surgery, in addition to other treatments targeting the cause, appropriate antihypertensive drugs should be used for antihypertensive treatment.
