The well-known Russian cardiologist Zaur Shugushev believes that the fear of death may be a manifestation of a heart attack. Moreover, what proceeds without other symptoms and is the most dangerous.
The classic signs of a heart attack include severe pain and tightness in the chest, shortness of breath, and other changes in well-being that are quite difficult to ignore. When they appear, a person usually seeks the help of a doctor or calls an ambulance, and in the hospital he is already being given the necessary therapy. But sometimes a heart attack can proceed, as they say, painlessly, becoming a silent heart attack. In this case, a person does not feel anything, and his heart is deprived of access to oxygen and goes through a process of scarring.

Silent heart attacks represent the greatest danger, since they can end in the death of the patient. That is why it is so important to listen to all the sensations of your body. But how do you recognize a painless heart attack? According to cardiologist Tugushev, expressed in an interview with Radio Sputnik, one of the most striking manifestations of such an asymptomatic heart attack is the sudden fear of death. Of course, we all experience horror before this phenomenon, which no one can escape. But attacks of fear are more characteristic of children, and in adulthood they, as a rule, do not appear for no reason. And if suddenly a person has a wave of real fear before passing away, then this may be a consequence of the death of myocardial cells.

Another manifestation of such a quiet heart attack, the cardiologist called a breakdown, which also occurs for no reason. (READ MORE)
