Abstract

Cardiovascular mortality and morbidity are higher in patients with chronic renal disease than in the general population. Patients with chronic renal disease are in the highest risk group for thromboembolic disease and many clinical trials have demonstrated the greater safety and efficacy of low-molecular-weight heparin (LMWH) versus unfractionated heparin (UFH). LMWH is cleared only by the kidneys while UFH is cleared by the renal and hepatic routes. Furthermore, LMWH has a significant accumulative effect in patients with impaired renal function (creatinine clearance <30 mL/min). The aim of this study was to evaluate the risk of bleeding when LMWH is used as an anticoagulant in hemodialysis or for treatment of acute thromboembolic disease in patients with renal failure. Twenty-one adult patients were enrolled, 13 with end-stage renal disease requiring chronic hemodialysis and 6 with acute thromboembolic disease and severe renal insufficiency (creatinine clearance <30 mL/min). ...
