Your body can sometimes send warning signals when something is wrong with your heart or circulation. But there is an important distinction: a heart attack does not always give you a month of warning, and symptoms can appear suddenly or develop gradually. Some heart attacks begin with mild discomfort before becoming more serious.
Knowing the warning signs can help you recognize an emergency and seek treatment before precious time is lost.
- Unusual or Extreme Fatigue
Feeling unusually exhausted, weak, or lightheaded—especially when it is out of proportion to your activity—can accompany a heart attack. This may be more noticeable in some women and older adults, and it should not automatically be dismissed as ordinary tiredness. - Pressure, Pain, or Discomfort in the Chest
One of the most recognized warning signs is discomfort in the center of the chest. It may feel like pressure, squeezing, fullness, heaviness, or pain, and it can last for several minutes or disappear and return.
The discomfort may also spread to the arm, shoulder, back, neck, jaw, or upper stomach.
- Shortness of Breath
Suddenly struggling to breathe or becoming unusually breathless can be a warning sign of a heart attack—even when there is no obvious chest pain.
