Low-molecular-weight or Unfractionated Heparin in Venous Thromboembolism: The Influence of Renal Function

Abstract

Conclusions

In comparison with low-molecular-weight heparin, initial therapy with unfractionated heparin was associated with a higher mortality and higher rate of fatal pulmonary embolism in patients with creatinine clearance levels >60 mL/min or <30 mL/min, but not in those with levels between 30 and 60 mL/min.
