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