Hi there- Yes this lady definitely needs to follow up with her family physician about the most appropriate tests. However I do think you should recommend a Cardiology consult. The fact that she has known valve issues coupled with a concerning family history evidences this. Available tests include a stress test(MPI), coronary angiogram or utilizing a cMRI- choices are there...plus more based on symptomology. Your job is to advocate for her, and sounds like she is asking for some education- Good luck.
