theres a couple complicating factors. Including some prior heart conditions and being on BP medicine, and all this stuff is way over my head. But right now he is doing well. Waiting on the specialist to get a final word in. He had a couple stints(sp?) put in, and since then he hasn't had another attack. He had three the couple hours before the surgery. Hopefully no more surgery and they just need to monitor.
apparently they didn't put him fully out while putting in the stints. At first he was asking questions, and the doctor had to ask him to stop so he could focus. Then my grandfather starts cracking jokes which apparently delayed the surgery. So they had to ask him to not speak the rest of the time. he then starts humming Christmas hymns the rest of the time.
family has got in to see him throughout the day and he seems to be in good spirits and his old cantankerous self.
