D-dimer to Improve Anticoagulation Outcome During ECMO loNg-term supporteD (DIAMOND)

April 13, 2023 updated by: Litao Zhang, Wuhan Asia Heart Hospital

D-dimer to Improve Anticoagulation Management in Adult Patients Supported With Extracorporeal Membrane Oxygenation: a Prospective Cohort Study

This was a prospective, cohort study.

Study Overview

Detailed Description

Adult Patients receiving ECMO surpport in Wuhan Asia Heart Hospital were enrolled by cohort. Unfractionated heparin was used for Anticoagulation therapy, APTT or Anti-Xa activity is monitored for dose adjustment. Meanwhile, D-dimer is 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). All patients were followed up The occurrence of endpoints during in-hospital and 30 days after discharge, including bleeding events, thrombotic events and all-cause deaths were recorded.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: DIAMOND group
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).
D-dimer-guided adjustment stratege
Other Names:
  • Heparin
Active Comparator: Control group
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.
0.3-0.7U/ml of anti-Xa activity or APTT 1.5-2.5 times of control
