If a stress test was not done and he had an MI, then you have a leg to stand on. If you do a test and then not address the positive test and a bad outcome happens, then you are on shaky ground.
I think the past this either
1. Do not do stress test, deem it emergent, and then if he had an MI then it was an unknown issue before procedure. Happens all the time in medicine
2. Do a stress test and if you deem a cath would delay a very imp procedure, then talk to the family/document their wishes. If they want the heart evaluated before Colectomy or colectomy knowing risks of positive stress test, then document their understanding/wishes
Doc took the worse path IMO by doing a test, having a positive result, then not following up (atleast I assume it was not documented). Now you have a sad/pissed off family who was not able to help direct their family's medical care
For any trainees reading this thread, I want to stress that this is exactly correct in my opinion. I also work in a preop clinic seeing the very high risk patients in an effort to optimize them, as best as possible, for surgery.
Cancer surgeries fall often into an ugly gray zone. Wait too long and it might progress to the point of resection no longer being an option. But, ignore symptoms and bad things can happen even if the procedure is technically perfect.
True shared decision making with the patient is the key. Sometimes patients will surprise you with the route they choose and why. Just give them the known facts and potential outcomes, in simple terms, and talk them through what it can mean.
Case in point: Years ago I saw an older patient who was scheduled for cervical spine surgery due to critical stenosis causing progressive loss of motor function. Patient had a prior history of NSTEMI many years prior. NSQUIP & DASI scores said consider further cardiac workup.
Obviously, given that the patient was loosing ability to use their hands tilted the scales toward just proceeding to surgery. After discussion with the patient, they chose to do the cardiac testing because they never wanted another heart attack again - “worst time of my life”. Surprisingly, they were ok with loosing use of hands if it meant no MI.
Fast forward - ended up having single vessel critical stenosis, got stented, waited a few months, then spine surgery. Patient was thankfully to everyone for all of their care. They kept / regained some motor function after the surgery compared to when initially saw them in clinic.
You just never know…
