Prayer request

At noon today my 81 year old father will have a heart cath. Around 20 years ago he had a triple by-pass. A few years ago he began having problems with his heart and had a cath performed and did not get real good news, but the doctors did not try to do anything about it. Lately, he has been having problems again and recently ended up in the ER one night with chest pains. He is having another cath today to find out exactly what he is dealing with and possible options. Please keep him in your prayers today. Thank you.
