My husabnd had his AVR 7 1/2 years ago and went for his semi-annual cardio visit. I went with him and everything was fine. They did a EKG and said it looked perfect. Before we left his cardio told him to add a 81 mg. aspirin every other day to his meds. I don't think he needs this and don't want to mess with his INR as he is almost always in range and even had his colonoscopy in Nov. while on coumadin with no problems. How many of you on coumadin take a low dose aspirin also? Thanks in advance.
