  Purpose

Concentration determinations of anticoagulants require plasma instead of whole blood, and results are not immediately available to clinicians. Monitoring anticoagulants concentration along with bedside methods may provide an alternative guide for administration of the NOAC.

The purpose of this investigation is to compare bedside coagulation assays in whole blood with plasma concentrations of the new oral anticoagulants (NOAC) in patients treated with therapeutic dosis of NOAC.

Healthy volunteers without medication
Phenprocoumon
Patients receiving Marcumar having target INR 2-3
Dabigatran
Patients receiving therapeutic dosis of Pradaxa
Rivaroxaban
Patients receiving therapeutic dosis of Xarelto

Detailed Description:

This open-label study will be performed by ex vivo investigations. Patients receiving the NOAC as dabigatran or rivaroxaban in therapeutic doses are recruited and informed consent of two blood sampling times will be obtained in correlation to the time of drug intake (two and 24 hours after drug intake). The bedside measurements will be performed and compared directly with the concentrations determined by plasma concentration assays. These investigations will be performed at the department of Angiology at the university hospital Frankfurt.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Patients indicated for NOAC-therapy

Criteria

The indication for the use of NOAC is provided by the attending physician. The criteria for inclusion and exclusion criteria for the use of the new oral anticoagulants must meet appropriate eligibility criteria and the clinical guidelines that are described in the SOPs.

Patients treated with dabigatran 2x150mg / d for the prevention of stroke and systemic embolism in non-valvular atrial fibrillation are included.

Moreover, patients treated with rivaroxaban 20 mg / d for DVT prophylaxis and treatment of recurrent DVT or PE are included.
