I've just seen this thread, and there are some, in fact one, post that got my goat, so please forgive me for the following rant.
This case illustrates what's wrong with modern medicine. If you don't know what is wrong on history, you are very unlikely to ever make a diagnosis. We no longer listen to our patients, and rely far to heavily on investigations. The art of taking a history has been lost as we spend less and less time in consultation. Over reliance on CT...., a CT chest increases the life long risk of breast cancer by 15%, so you better have a very good reason for doing one in a female, especially a young one, and an even better reason for doing a repeat CT. Don't even get me started on the rip off "heart scans".
If you ask the village policeman, what is the cause of chest pain brought on by exercise and relieved by rest, he will know. However the original physicians seem to have been thrown off track by a negative exercise test. All goes to show every test has a false negative and a false positive rate, and every test is open to interpretation. Moral of the story, make a clinical diagnosis and then use investigations to prove it, not do a million test to CYA and pray one of them comes up positive.
I suspect this is litigation driven, the legal system probably respects a typed report from an investigation, as fact, but can't weight gut feel, experience, intuition etc.
The other problem is sub-specialsation, every one seems to be quite comfortable saying it's not cardiac, not respiratory, not gastro, but very few are capable of saying what it is. A physician consultation should last the best part of an hour with at least 30 minutes on history. With due respect "cruising home", the only true generalists left seem to be ED physicians. No one else ever seems to see hot undifferentiated cases fresh off the street. Every one else sees selected syndromes filtered through the system.
Who would I take advice from? the clinician at the coal face, in daily contact with patients, or the PhD academic researcher, with a narrow field of interest/expertise?
Rant over, phew!
Pleased this eventually got sorted, but what a run around. RetNav only a few months left before you'll be in the water, enjoy!
