@marnie10- I had a stent placed in my lower decending artery back in 14 and was on Plavix for a year before the cardiologist decided that a 81 mg aspirin was adaquate. I think that most patients that have heart work done are often on a blood thining type of med to minimize possible clotting problems. I'm also on a beta blocker to slow down the heart. Sounds like your daughter has been through a lot already in her life! What a great asset she has like a mom like you!
God bless you both!
