I did get a suggestion from another doctor (at church) and wrote my cardiologist that I wanted a nuclear stress test instead of a catheterization. He said "we can do that."
The cardiologist called me on my cell phone as I was on the way to a lecture by a visiting speaker. After the lecture I had to hurry to Greenville to pick my husband's aunt up at the hospital, where she was ready to come home after recovering from surgery. Home after 9 pm.
