The idea was told to me by a (non-cardiologist) doctor who knows one of the top cardiologists in NYC. His description to me was fuzzy and non-specific and like you I haven't been able to really find anything online that would fit with it. So who knows. This doctor also got me an appointment with this cardiologist later this week to consult on the situation. Given his credentials and particular expertise in imaging and risk stratification, I'm hopeful it will be a valuable session.

Also tomorrow morning I am going in to have a CT Angiogram.

I really do appreciate the back and forth on here. This has been very difficult for me to deal with, as I'm sure it is for many here.
