Patients with hypertension need to adopt a comprehensive approach to reduce their blood pressure, primarily comprising two aspects: On one hand, they should regulate their lifestyle for treatment purposes, which includes maintaining a long-term low-salt and low-oil diet, consuming more vegetables and fruits, regularly engaging in physical exercises and labor, keeping a healthy weight level, avoiding fatigue, not staying up late at night, and maintaining a good emotional state. On the other hand, suitable antihypertensive medications should be chosen based on the specific conditions of the patients and used long-term. If necessary, a combination of antihypertensive drugs may be required. Effective control of blood pressure can only be achieved by combining lifestyle adjustments with medication.

How to monitor blood pressure in hypertensive crisis

If a patient experiences a hypertensive crisis, it is recommended that they use an electrocardiogram monitor. This can effectively monitor changes in the patient's heart rate, blood pressure, and pulse. If there is a rise in blood pressure, it can be immediately observed. The occurrence of a hypertensive crisis is very dangerous and can lead to complications, potentially causing damage to liver and kidney functions, and leading to cardiovascular and cerebrovascular events. In particular, it is prone to causing cerebral hemorrhage or coronary heart disease. In such cases, it is crucial to actively use antihypertensive drugs to control symptoms. Regarding diet, it is important to maintain a light diet, especially limiting sodium intake, in order to control the phenomenon of high blood pressure in patients.

Difference between hypertensive encephalopathy and malignant hypertension

The difference between hypertensive encephalopathy and malignant hypertension can be discerned from their names, indicating they are different conditions. Hypertensive encephalopathy refers to a condition where blood pressure rises sharply in a short period, with diastolic pressure exceeding 120 mmHg and systolic pressure exceeding 200 mmHg. This dramatic increase in blood pressure causes cerebral vasospasm and increased cerebral perfusion pressure, leading to various manifestations of cerebral edema, primarily severe headache, nausea, vomiting, seizures, and even brain herniation. The emphasis is on the rapid rise in blood pressure over a short term and its impact on the brain, specifically cerebral edema. Malignant hypertension also involves a rapid increase in blood pressure to extremely high levels over a short period. However, the focus of malignant hypertension is on the impact on multiple organs throughout the body, including the brain, but also severely affecting the heart, potentially causing acute left heart failure and pulmonary edema. In the kidneys, it can lead to acute renal failure, characterized by reduced urine output or anuria. Thus, malignant hypertension emphasizes the effects on multiple vital organs, whereas hypertensive encephalopathy focuses primarily on the impact on the brain and central nervous system. Hence, there are some distinctions between the two conditions.

How to Read a Blood Pressure Monitor for High Blood Pressure

As living standards improve, a blood pressure monitor has become an essential medical device in households. Electronic blood pressure monitors are very convenient for measuring blood pressure, especially for patients with hypertension. They allow patients to measure their blood pressure timely and adjust medication dosages accordingly. How to read a blood pressure monitor varies with different models. Typically, on an electronic blood pressure monitor, the first line displays the systolic pressure, also known as high blood pressure; the second line displays the diastolic pressure, also known as low blood pressure; and the third line displays the heart rate. These readings can help you know your systolic and diastolic pressures.

How to treat hypertensive encephalopathy

The treatment goal for hypertensive encephalopathy is mainly to rapidly reduce blood pressure to a reasonable range. Typically, intravenous antihypertensive drugs are administered to decrease blood pressure by 20%-25% within the first hour, followed by oral antihypertensives or continued intravenous treatment to further reduce it to a more reasonable level. Hypertensive encephalopathy often accompanies cerebral edema, and patients may experience increased intracranial pressure. At this point, it is necessary to administer dehydrating agents such as mannitol to treat the cerebral edema. If the patient experiences seizures, which can cause an increase in blood pressure or difficulty in reducing blood pressure, sedative anticonvulsant drugs must be administered to control the seizures. If the patient shows signs of heart failure, diuretic treatment should be initiated. Additionally, high concentration oxygen therapy under high pressure should be administered, which can be delivered through nasal cannula. If nasal oxygen therapy is ineffective, non-invasive ventilation or even intubation with invasive ventilation may be used to provide high concentration positive pressure oxygen therapy.

The difference between hypertensive crisis and hypertensive encephalopathy

Both hypertensive encephalopathy and hypertensive crisis involve a rapid increase in blood pressure, symptoms of headache, restlessness, nausea and vomiting, palpitations, shortness of breath, and blurred vision, with systolic pressure increasing to 200 mmHg and diastolic pressure to 120 mmHg, typically presenting similar clinical blood pressure readings. The main difference between the two is that hypertensive encephalopathy is based on excessively high blood pressure in patients with severe hypertension. Furthermore, hypertensive encephalopathy can lead to clinical signs of cerebral edema and increased intracranial pressure, whereas hypertensive crisis occurs when blood pressure suddenly rises over a short period, causing symptoms due to excessive secretion of catecholamines driven by increased sympathetic nervous excitement.
