What Causes Severe Sweating, Chest Pain, Dizziness And Fainting Spells?

A few months ago while at a ball game I started sweating profusely, had chest pain, was dizzy, and blacked out for a few seconds. I had to go to the restroom and set for a while to gather myself. Since then I've had slight chest pain that comes and goes. I'm 32 and have neglected it thinking there's no way that it was a heart attack but lately I'm starting to think that maybe it was. Am I right to think this?
