heart attack
"Dad has been on warfarin/Coumadin for over 10 years. He started taking it after he had a triple bypass. He has since had two stents, one at a time. He is 83 years old, and has been getting along great. He recently got sick, went to hospital. All of his symptoms could have been side affects from the warfarin. The doctors would not put down a reason for his getting ill. I would give warfarin a good rating. By the way, if you start interacting with cartoon characters on TV, or can watch a movie, just by closing your eyes, don't be alarmed. You're not alone. Just try to have fun with it. That's what dad does."
