Had two stents in 2004, still holding up. I think they were made by Honda

My doc said that the only reason I didn't have an actual heart attack, with a
95 and 99% blockage, was that I worked out regularly. That has kept me
going to the health club.
The relief I felt after they put them in was amazing, only spent one night in the hospital.
I'm sure your Dad will do great!
Now, if they would only come up with a quick fix to the big "C". ???
