Symptoms of a heart attack vary. Some people have mild symptoms. Others have severe symptoms. Some people have no symptoms. Get help right away if you think you're having a heart attack. If someone is unconscious and you think they're having a heart attack, first call the emergency services, then check if the person is breathing and has a pulse. If the person isn't breathing or you don't find a pulse, only then should you begin CPR.
