But in some cases, acute myocardial infarction may be masked by symptoms characteristic of very different diseases.

Unrecognized myocardial time makes it impossible to provide medical assistance during the so-called "therapeutic window". It is when this assistance is the most effective and can reduce the area of ​​myocardial necrosis.

Today I want to tell you about the most atypical forms of myocardial infarction, which can be confusing.

At the forefront in this situation leave signs of stagnation in the light against the background of an acute cardiovascular insufficiency. There is a cough with frothy sputum, dyspnea.


Extensive myocardial infarction leads to a drastic violation of the contractility of the left ventricle. Due to the fact that the heart is unable to pump blood properly, there is a drop in blood pressure.

Vascular collapse can lead to symptoms such as:

  • blackout,
  • clammy cold sweat,
  • palpitations,
  • loss of consciousness.

brain symptoms

These include:
