and even worsened--despite all the usual symptomatic treatments. Damn. Your veterinarian would have performed or ordered radiographs- at a minimum- and seen at least some evidence to support the former and rule out the earlier assumptions. With those findings, her physicians would then have been expected to order that MRI, echo, and perhaps some other imaging studies. I strongly suspect had she been male they would NOT have ignored her continuing/worsening symptoms. As much as the literature has stressed the symptoms of cardiac insufficiency and MI in women, they still tend to be ignored--that "protective estrogen effect" ya know. 
Now with this administration and HHS (under RFK JR) determination not to include women, race, or any other variable long shown to present differently for many syndromes OR at greater risk in any targeted interventions or study, women like her will fall through the cracks even more.
No. I do not consider this a medical mystery. More like medical malpractice!
