Looking at the photo of him in the ambulance (linked in the story to here: http://twitter.com/mattgutmanABC/status/276778188116480002/p...), I'm somewhat skeptical either of the medical claim or of the ability of the EMTs who are treating him.

First, he's not on oxygen. Step 1 for a suspected heart attack patient.

Second, he's got a shirt, a sweater and a blanket on top of him. Step 2 for a potential MCI is to expose the chest and get him on a "monitor" (combination EKG/AED), which it appears is at his feet.

Third, unless he fell and injured his head, neck or back, there is no reason to have him in full spinal immobilization as they appear to have done.

This is not a question of not having training or equipment--from the look of the photo, they have both. I'm reading a lot into a single snapshot, but being transported via ambulance in the US would look nothing at all like this.
