Outcome Measures

Primary Outcomes (2)

  • Thrombotic events

    Stroke, DVT, PE, Peripheral arterial embolism, ACS etc.

    24 months

  • hemorrhagic events

    cerebral hemorrhage,Gastrointestinal bleeding etc.

    24 months

Secondary Outcomes (1)

  • all-cause deaths

    24 months

Study Arms (2)

DIAMOND group

EXPERIMENTAL

D-dimer and anti-Xa are mornitored. If D-dimer levels continue to rise (\>1.5 times previous result ), increase the dose of heparin to reach the upper limit of the treatment target; If the D-dimer levels is stable (\<1.5 times previous result ) or is decreasing, the anticoagulation dose is maintained at current level (no active bleeding) or decreased (active bleeding).

Diagnostic Test: D-dimer-guided adjustment stratege

Control group

ACTIVE COMPARATOR

Heparin dose adjusted according to anti-Xa activity or activated partial thromboplastin time (aPTT). The target range is aPTT 1.5 to 2.5 times the upper limit of normal or therapeutic anti-Xa levels (0.3 U/ml to 0.7 U/ml) for unfractionated heparin.

Diagnostic Test: Thepeautic-heparin therapy

Interventions

D-dimer-guided adjustment stratege

Also known as: Heparin
DIAMOND group

0.3-0.7U/ml of anti-Xa activity or APTT 1.5-2.5 times of control

Control group
