Update on my dad

My dad is doing better. He is off most of the machines and they allowed him to eat and get up and shower today. All of that raised his spirits a lot. They got the results from the tests they've run so far and they think it is a blockage in one of his arteries. Because he has responded so well with the blood thinners and other medicines they have given him, they feel they may be able to treat the blockage with medicine,  instead of surgery. They will know more after they do the catheter tomorrow morning. I am not sure why they didn't do it today, like they had said they were going to originally, but dad is glad that they said they probably would release him tomorrow afternoon. Thank you for your prayers for him.
