Melinda,
I'm sorry to hear that your husband had problems with his bypass surgery and heparin induced thrombocytopenia. It really hit home. My husband had HIT after bypass surgery earlier in the summer. He was home 3 days and returned to the hospital with a pulmonary embolism. Fortunately the drop in platelets - heparin connection was picked up quickly, but it was a very scary time. Thats an understatement... He is now doing well - has an ivc filter, and is on coumadin.....
A Dr.JohnFrancis PHD. at Florida Hospital in Orlando has done a lot of research and education in this area. Echelon.ed.com has a course based on his research that is easyish to understand and it is offered free. It helped me to understand what was going on, the treatment etc. It seems that this complication is not as rare as once thought...
Feel free to e-mail, my best, Lyn
