Death due to sudden cardiac arrest is often associated with the so-called silent heart attacks that occur early in life and often go unnoticed by the patient, says JAMA Cardiology.
To such conclusion scientists have come, having analysed data about 5869 inhabitants of Northern Finland, who died of a heart attack between 1998 and 2017.
It turned out that the 1322, there were scars on the heart that indicate a heart attack, which occurred long before death. People have not noticed this and did not go to doctors, because they were confident that their health is all right.
According to scientists, the quiet symptoms of heart attack are nausea, excessive sweating, upset stomach, muscle pain, numbness of hands and feet, dizziness, sudden fatigue, and discomfort in the chest area.
