I received a letter from my hospital. The letter states "there have no reports [presumably from my hospital] of patients who have developed this infection to date". Coincidentally, I am working with my doctors to understand the cause of a recent bout of arrhythmia and chest pain (among other symptoms). I've experienced three similar events since my OHS, where each event was more serious than the last. When an ESR test indicated the potential of infection, I floated the idea of an infection from the contaminated equipment. That idea didn't get much traction; though I got the impression my doctor wasn't too familiar with the case, but knowing her, I'm confident my query caused her to do some research.
I seriously doubt my situation has anything to do with contaminated heater cooler, but it is on my radar as we try to get to the bottom of whatever it is that is going on.
