Heart Attack Signs and Symptoms

The Centers for Disease Control and Prevention estimate that about 720,000 Americans have a heart attack each year.

Act Fast When A Heart Attack Is Suspected

When a heart attack strikes, the faster you are treated, the lower your risk is of heart muscle damage or death. It's important to know the signs and symptoms of a heart attack, and act immediately by calling 911, even if you are not sure you're having a heart attack. 

All of the following can be signs of a heart attack:

  • Chest discomfort, pressure, tightness
  • Fainting
  • Lightheadedness
  • Nausea, vomiting, belching
  • Pain or discomfort in the center of the chest (for women)
  • Palpitations
  • Shortness of breath
  • Squeezing that spreads through the chest and/or radiates to other areas of the body
  • Sweating
  • Unusual fatigue

For a cardiologist at St. John’s, call 877.753.6248, 24 hours a day, seven days a week. For emergency heart care, call 911.
