Exams and Tests

Doctors can usually diagnose a heart attack based on a combination of:

  • Your signs and symptoms
  • Your medical history
  • Electrocardiogram (EKG) that can detect and record the heart's electrical activity and show signs of heart damage
  • Blood tests that check the levels of certain proteins released into the bloodstream as heart muscle cells die; troponin tests, CK or CK–MB tests are commonly used and may be repeated over a period of time.
