Hi Colleen - Thanks for checking. My husband is hanging in there, however, he seems to be losing his energy. I am taking him to the drs. tomorrow to see what she thinks about the issues he is having. I am going to ask her about getting him on oxygen to see if that helps him since he only has the main artery open. Since he was a smoker for 70+ yrs., I would think it might help? It may not be possible, however, it doesn't hurt to ask. I will know more hopefully tomorrow afternoon after we see the dr. And he has an appt. with his cardiologist at the end of July, so maybe there is something else he can suggest? Hope you have had a Happy 4th of July. Thanks again for checking with me. FYI - I am doing OK right now.
