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".

Hypertension is a common clinical picture, and an important risk factor for coronary heart disease. Hypertensive episodes, also known as severe hypertension, a rapid rise in blood pressure from normal levels, may occur in 1% of patients with chronic hypertension. There are two clinical types: acute hypertensive crisis, often accompanied by target organ damage, and hypertensive urgency.
