Not a case study, just bad heart/blood pressure issues. She's already had one stroke and two stents. She has A-fib and damage to one of her ventricles from an "undiagnosed" heart attack. (It wasn't diagnosed as a heart attack and she didn't have any symptoms of a heart attack, but she has damage that's evidence of a heart attack.) So they're trying to keep her heart from over working itself, trying to keep her arteries from clogging any worse, while trying to keep the stents from throwing any more clots while also not overwhelming her kidneys and liver.

So she's on a low dose of three blood thinners for the time being to try and protect her heart and lungs and eyes from further damage without destroying her kidneys.
