NCT00796692

Brief Summary

Low-molecular-weight heparin (LWMH) appears to be at least as effective and safe as standard, unfractionated heparin (UFH)for the treatment of patients with deep vein thrombosis(DVT) and may also be so in patients with pulmonary thromboembolism (PTE). Only limited data are available on the evaluation of body weight adjusted LWMH and standard UFH for the initial treatment of PTE in Chinese population. The aim of this study is to determine whether body weight-adjusted, subcutaneous Nadroparin is as effective and safe as UFH for treatment of patients with objectively documented PTE.

Outcome Measures

Primary Outcomes (1)

  • Clinical and image(including V/Q scan and CTPA) improvement

    Time Frame: 14days

Secondary Outcomes (1)

  • Recurrent venous thromboembolism(VTE), major bleeding death Heparin-induced thrombocytopenia

    3 months

Study Arms (2)

Group 2

EXPERIMENTAL

Low molecular weight heparin

Drug: Nadroparin

Group 1

ACTIVE COMPARATOR

Unfractionated heparin(UFH)

Drug: Unfractionated heparin(UFH)

Interventions

LMWH is given with a weight adjusted dose of 86 international anti-factor Xa units of nadroparin (Fraxiparine) per kilogram of body weight(86 anti-factor Xa IU/kg) subcutaneously every 12 hours,which will be used at least 5-7 days.

Also known as: Low moleculor weight hepatin
Group 2

UFH is received with an initial bolus dose of 80 IU per kilogram, followed by a continuous intravenous infusion at an initial rate of 18 IU per kilogram per hour. The dose is subsequently adjusted so that the activated partial thromboplastin time (APTT) would be 1.5 to 2.5 times the control value in normal subjects. The tests are performed 4 hours after the start of treatment, whenever a sub-therapeutic APTT had been measured after a dose adjustment, and otherwise daily.UFH will be used at least 5-7 days.

Also known as: Standard Unfractionated heparin
Group 1

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • to 75 years of age

You may not qualify if:

  • Unfractioned heparin anticoagulation for more than 36 hours prior enrollment,

  • Pregnant status;a life expectancy of less than 3 months;
  • Previous thrombocytopenia induced by heparin
  • Thrombocytopenia \< 100000/mm3,
