A heart attack is not usually a sudden event without warning. In most cases, the body begins to send clear signals several days before a severe heart attack occurs. The problem is that many people ignore these warnings because they mistake them for tiredness, stress, or common problems.
Recognizing these symptoms early can make the difference between life and death.
Why does the body warn before a heart attack?
Before a heart attack, the arteries that carry blood to the heart begin to become progressively blocked. This reduces the flow of oxygen to the heart muscle, causing small alterations in the body that manifest as physical symptoms.
These signs can appear up to seven days before the main event.
1. Extreme and unexplained fatigue
This is the most silent and dangerous symptom.
It is not normal tiredness. It is a deep feeling of exhaustion that appears even after sleeping well or without physical exertion. Many people describe it as a sudden weakness that prevents them from doing simple activities, such as walking, showering, or getting up from a chair.
This symptom occurs because the heart can no longer pump enough oxygen-rich blood to the body.
2. Shortness of breath
