Pray for my dad

My dad had two stints put in his heart this last Monday and today he had a heart attack and they had to go in and put another stint in. He is doing well, just very tired. The doctor said he MUST start exercising and NO MORE SMOKING!! Please keep him in your prayers as well as my mom as this is very emotionally draining on her as well as me and my sisters but as a mom we are the stone of the family and have to be everything to everyone.
