On one photo where she wasn’t wearing hose, her ankles appeared to have darkened patches. That goes with a type of edema that accompanies heart disease. For comparison, one of Nancy Reagan’s last photos, where she’s in a wheelchair, shoes the same sort of discoloration on the ankles. It isn’t exactly blue, more of a bronze.
I’m pretty sure the cankles are structural and have been there forever.
Those hands look swollen.
