Glad to hear that something worked!
As far as other medical problems, don’t go there. I am sure your vet will bring it up if additional tests are needed. Once a year for an annual checkup and labs, heartworm check is more than enough.
There is concern for over diagnosis http://skeptvet.com/Blog/?s=overdiagnosis
or even worse “Munchausen Syndrome by Proxy” it can occur with pets, veterinarians keep their eyes open for it.
Focus on getting her well nourished and settled in her new home so she can tolerate the heartworm treatment. That is enough to worry about for now.
