The article is professionally consulted by Dr. Nguyen Van Duong - Interventional Cardiologist, Vinmec Central Park International General Hospital.

Malignant hypertension or malignant hypertension has dangerous symptoms such as blurred vision, inability to concentrate, anxiety, weakness in limbs. If not treated in time, there may be strokes, angina (acute myocardial infarction) or worse, heart failure - acute pulmonary edema. That is why it is called the "silent killer".

You will be diagnosed with hypertension if one or both of the following occur (according to the World Health Organization):
The systolic blood pressure reading (SBP) is greater than or equal to 140 mmHg; The diastolic blood pressure (DBP) reading is greater than or equal to 90 mmHg. Malignant hypertension is a hypertensive emergency with end-organ damage, accounting for 1% of hypertensive patients; Common in young people, Africans, people with a history of kidney failure or renal artery stenosis... The disease will affect organs sensitive to high blood pressure such as: brain, heart, kidneys, eyes.
A malignant hypertensive crisis requires immediate treatment as symptoms are manifested by severe internal organ damage. If not treated promptly, you are likely to face serious health-related consequences such as heart failure, acute myocardial infarction, stroke, blindness, kidney failure... The fact is Malignant hypertension can be directly life-threatening if not treated promptly.

Malignant hypertension occurs mainly in people with a history of hypertension. It is also common in men and smokers. On the other hand, people with blood pressure readings above 140/90 mmHg have a very high risk of facing malignant hypertension. According to a 2012 clinical review, about 1-2% of people with hypertension develop malignant hypertension.
Besides, some specific health conditions can also cause malignant hypertension such as:
Renal dysfunction or kidney failure; Use of drugs such as cocaine, amphetamines, birth control pills, or monoamine oxidase inhibitors; Preeclampsia is common in 20 weeks pregnant, but can sometimes occur earlier in pregnancy or even after delivery; Spinal cord injury; Renal artery stenosis; Aortic valve stenosis ; Do not take medication for high blood pressure. If you are suffering from high blood pressure and have any unusual symptoms, immediately go to the nearest medical facility for timely treatment and emergency care.

Many people like to say that high blood pressure is a "silent killer", because it does not have any obvious signs or symptoms but has serious health consequences. However, unlike normal hypertension, malignant hypertension has obvious symptoms including:
Vision is changed, and the eyes are often blurred; Chest tightness, feeling of pressure or pressure in the chest; Forgetfulness, decreased ability to concentrate; Nausea and vomiting; Numbness of facial muscles and extremities; Shortness of breath; Headache; Difficulty urinating and urinating less. Malignant hypertension may also result from a case of hypertensive encephalopathy. This condition directly affects your brain, including symptoms such as:
Severe headache; Blurred vision; Dementia; Indifference to everything; Convulsions. Numbness or weakness, hemiplegia. Cases of hypertension and hypokalemia:
This is a fairly common clinical form with special attention. Patients with this condition will find it very difficult to control their blood pressure and are prone to dangerous events such as:
Events due to hard-to-control blood pressure such as stroke; Events due to hypokalemia such as arrhythmias, sudden paralysis of the lower extremities...; Doctors may not initially appreciate the magnitude of the problem, thinking of hypokalemia due to simpler causes such as laboratory tests, diuretics, not eating enough, etc.).
Therefore, it is necessary to have a right, quick and comprehensive view of this condition, avoiding ignoring cases that can be completely cured; avoid complications, unfortunate events that could have been prevented for the patient.

Malignant hypertension can cause many serious complications to the three main organs of the heart, kidneys and brain. Many patients only develop hypertension when there is a complication in one of these organs, but by then it is quite late.
In the heart, hypertension can cause left ventricular hypertrophy, heart failure, coronary artery disease, aortic aneurysm, arrhythmia, sudden death; In the kidneys, high blood pressure can cause kidney failure; In the brain, high blood pressure can cause a stroke (usually cerebral infarction, in addition to cerebral hemorrhage, subarachnoid hemorrhage). And yet, high blood pressure is also a cause of metabolic syndrome (a syndrome including abnormalities in the body's metabolism, which is a risk of diabetes, coronary heart disease, stroke), damage eyesight, dementia... The higher the blood pressure, the greater the risk of complications.

Malignant hypertension can be directly life-threatening and requires medical attention as soon as possible to safely lower blood pressure to ideal levels and avoid potentially dangerous complications. out.
