What is hypertensive crisis

What is hypertensive crisis
sharp rise in blood pressure - the most common cause of ischemic stroke and cerebral hemorrhage.We will understand that such a hypertensive crisis.

Typically, hypertensive crisis develops at sharp discontinuation of antihypertensive agents, and may be the first manifestation of hypertensive disease or symptomatic hypertension in patients who do not receive adequate treatment.Since hypertensive crisis related to the vast majority of stroke.

any of the three stages of primary hypertension or hypertension, can be considered a risk factor for hypertensive crisis - a sudden sharp short-term exacerbation of hypertension.Hypertensive crisis without reason considered to be urgent conditions: it is dangerous and its complications can result, for example, stroke.

Hypertensive crisis: as it happens?

Against stress caused by any provoking factor - fear, nervous or physical stress, the body is adrenaline or noradrenaline - depending on the stage of hypertension.This hormone causes a narrowing of the small blo

od vessels, allowing the body's blood pressure rises, sometimes - very sharply.If you are already exposed to hypertension, then such "jumps" can only aggravate the condition of the vascular system.

When blood pressure rises sharply, in all systems and organs of blood circulation, especially it is dangerous for the brain, cardiovascular and nervous system, lungs and kidneys."High blood pressure - is how much?" - A question of individual . sensitivity to increased pressure from everyone, for one will be high 250/140 mm Hg.Art, for another -. 130/90 already.

Hypertensive crisis: causes

In the early stages of the disease cause hypertension crisis is often the stress and its results - the release of adrenaline in the blood.It lasts a crisis can from several minutes to several hours.Tremors in the limbs or the entire body, palpitations, headache - symptoms of adrenal crisis, and the blood pressure rises slightly, and the consequences can not occur.

In the later stages of the disease hypertensive crisis may occur as a result of the release into the blood related to adrenaline noradrenaline.The main function of this hormone - the adaptation of the organism to stress due to change of weather, overeating, physical overexertion.As a result, release of noradrenaline prishodit vasoconstriction, while blood pressure rises and crisis symptoms appear.

Varieties and symptoms of hypertensive (hypertensive) crisis

Uniform classification of hypertensive crises is not there yet, because this state has a lot of symptoms and complications.There are uncomplicated and complicated hypertensive crisis;cardiac, brain without local disturbances of the nervous system and brain with local disorders of the nervous system, a generalized crisis in which the spasm of blood vessels captures several areas.

In uncomplicated hypertensive crisis we are talking about a sudden significant increase in blood pressure, which is accompanied by obstructed blood flow and cerebral neuro-vascular disorders.At the same time there are hormonal disorders.Uncomplicated hypertensive crisis usually passes rapidly usually not more than two or three hours, stopped by using antihypertensive drugs.

When hypertension II and III stages of developing complicated hypertensive crisis, which is the main danger - the defeat of the cardiovascular system, and as a complication of hypertensive encephalopathy, caused by violation of the blood supply to the brain due to the narrowing of his arteries.Hypertensive encephalopathy is fraught with stroke and Parkinson's disease, leading to permanent disability of the patient.

sharp narrowing of blood vessels that occurs when the blood pressure increase leads to the fact that the fluid in the bloodstream becomes cramped, and it starts to leak through the vessels in the brain and lung tissue.For this reason, cerebral edema and pulmonary edema - a frequent consequence of hypertensive crisis, as well as ischemic stroke, myocardial infarction and acute renal failure.

When hypertensive crisis generalized spasm of blood vessels captures several areas: brain, retina, kidney and heart.Symptoms of this condition are usually nausea, vomiting, headache, various disorders of the nervous system, visual disturbances, heart pain, heart rhythm disorders.

brain Hypertensive crises may extend to disorders of the nervous system and those without.Crease with nervous system has the symptoms: the patient has an increased emotionality, energy, which is then followed by irritability and tearfulness.In addition, there are violations:

  • sight (front sight in the eyes, double vision),
  • speech (deteriorating articulation, speech becomes slurred),
  • sensitivity (numbness of the fingers, chills),
  • gait (swinging, swaying from side to side).

With such Stroke occurs growing headache (first in the back of his head, and then in the eye sockets), nausea, vomiting, lethargy.

Emergency care for hypertensive crisis

If you are informed that suffer hypertension (some may not know!), Then you already know that the risk for hypertensive crisis.It is important to know exactly harbingers of crisis (if you are), and not to be afraid of an impending state of fear because everything only aggravate (funk - stress - adrenaline and so on).Take a soothing and all that you appointed doctor - this will help prevent the onset of crisis.

What do you do if it did happen?First of all - call "ambulance."Necessary before arrival "fast" action should discuss in advance with your doctor.In anticipation of the brigade "first aid" take the semi-sitting position, warm feet (it diverts part of the blood from the heart and brain), remove tight clothing, let fresh air into the room.If the doctor can not be arrived to arrest the crisis in place, the patient is hospitalized.
