I just got off the phone with Carolyn (my mother-in-law; my mother is also named Carolyn; the poor kids are going to think "Carolyn" and "Grandma" are interchangeable) for an update on Allan. He got home from the hospital on Monday, and is on a slow, steady program to get his strength back. The stent he has in is apparently coated in a medicine that helps dissolve the plaque directly at the site. Nurses are visiting about twice a week to check in on him and work on his rehabilitation, and treadmill tests are scheduled about two weeks out.
Hurrah, he's home!
