Cardiogenic shock

In heart failure, which worsens the course of myocardial infarction, there can be a sharp decrease in blood pressure, impaired blood supply to the organs, increased heart rate and loss of consciousness. This condition is called cardiogenic shock. It occurs at a critical time of myocardial infarction and in 60% of cases leads to death.

Cardiogenic shock - causes

The main factors affecting the development of this phenomenon, necrosis of the wall, covering the left ventricle, the gradual destruction of the myocardium, the rhythm failure and acute aneurysm. Cardiogenic shock is detected with a small myocardial infarction, if:

Cardiogenic shock - classification

There are several types of this state:

  1. Reflex shock, which is the least dangerous variety that does not result from the destruction of the myocardium, but is caused by a pain shock accompanying a heart attack. With the timely cupping, the pressure rises, otherwise the shock can develop into a true stage.
  2. A true shock that manifests itself in a vast heart attack. It occurs because of left ventricular dysfunction.
  3. AREA with its characteristics is practically not distinguished from the true form of shock, however they are more pronounced and last longer. Such shock does not respond to treatment and in 100% of cases leads to death.
  4. Arrhythmic shock appears due to the paroxysm of tachycardia, which occurs in conditions of atrioventicular blockade.

Cardiogenic shock - symptoms

The general condition of the patient is assessed as severe. Thus there are such signs:

At external survey the following are revealed:

Cardiogenic shock is the first medical aid

First aid includes ensuring patient's rest and prompt delivery to the hospital. Doctors can provide the patient with a series of activities on the way to a medical institution. This can be the following:

  1. Rid of pain with nitrous oxide.
  2. The introduction of mezaton (1%) intravenously and cordiamine (10%) intramuscularly.
  3. The first aid for cardiogenic shock is also based on kilo-radiotherapy.
  4. Drip drop of norepinephrine (2%).
  5. Carrying out a defibrillation of the heart, if the shock is caused by paroxysmal tachycardia.

Treatment of cardiogenic shock

Therapy is aimed at preserving the functions of the myocardium. Prevention is the main method of struggle.

If there is a rapid drop in pressure, the patient is injected with norepinephrine until the pressure reaches 90 mm Hg. Then they switch to dopamine, which positively affects the condition, expanding the cerebral vessels, vessels of the kidneys and other organs located in the abdominal cavity. If the pressure was stabilized, then dobutamine is added to the treatment.

Take preventive measures should be in the pre-infarcted state:

  1. Anesthesia with nitrous oxide, neiroletoanlagezii, electroanalgesia.
  2. Prevention of arrhythmia by the introduction of lidocaine, etatsizina and ornid.
  3. Carrying out fibrinological therapy.
  4. Getting rid of heart failure by using lasix, oxygen and strophanthin.
  5. The need for early hospitalization and providing the ward with equipment for intravenous administration of drugs.
