Can you clarify -- if you're comfortable sharing additional details -- did you have an "occlusion MI" heart attack, involving balloons / stents in the cath lab?

Most people assume that "heart attack" is a distinct clinical entity, but the majority (~80%) of elevated troponin levels are not exactly what comes to mind when people say "heart attack," but will often be described to patients as a heart attack (sometimes out of ignorance and others out of convenience, as the actual explanation for what is going on takes a lot more time and effort).
