Arms	Assigned Interventions
Active Comparator: B	Drug: Unfractionated heparin Unfractionated heparin 5000 IU thrice daily subcutaneously for 6-14 days.
Experimental: A	Drug: Dalteparin (Fragmin) Dalteparin 5000 IU once daily subcutaneously for 6-14 days.

Detailed Description:

The study was prematurely discontinued due to delay in overall study start-up and inability to meet pre-defined protocol recruitment milestones on June 30th, 2008. There were no safety concerns regarding the study in the decision to terminate the trial.
