Conclusion
Many people delay seeking medical attention because they are unaware that these symptoms can be associated with a heart attack; they believe that heart attack always hurts. The truth is that if you have any of these symptoms for 5 minutes or more you should see a doctor immediately. You should request an ambulance (by dialing 9-1-1) or ask someone to take you to the nearest hospital emergency room. You should not drive to the hospital, because if you have a heart attack, you could put yourself and others in danger. However, understand that these signs do not mean that you will have a heart attack immediately after experiencing great fatigue or any of the other signs listed below. They just indicate that there may be a problem with the heart and it is important to see a doctor.
