 Low molecular weight heparin LMWH provides a safe and effective alternative to UFH for hemodialysis anticoagulation. While unfractionated UF heparin has been implicated in hyper-lipidemia, the effect of LMWHs on the lipid profile in non-diabetic patients on chronic hemodialysis remains controversial. The effect of LMWH in diabetic patients, a high risk group for developing hyper-lipidemia and cardio-vascular disease, has not been studied.
