The purpose of this study is determine whether point of care coagulation testing is able to map the anticoagulatory effects of new oral anticoagulants dabigatran and rivaroxaban. Used as devices are thrombelastometry/-graphy (ROTEM, TEG)and multiple platelet function analyzer (Multiplate).
Clot Formation and Platelet Aggregation in Point of Care Testing
||Observational Model: Case Control
Time Perspective: Prospective
||Monitoring The Anticoagulatory Effects of Dabigatran and Rivaroxaban On Plasmatic and Cellular Coagulation by Rotational Thrombelastometry/-Graphy and Multiple Platelet Function Analyzer

| Primary Completion Date:
||March 2014 (Final data collection date for primary outcome measure)
Patients receiving dabigatran or rivaroxaban in therapeutic doses are recruited. Blood will be taken twice in correlation to the time of drug intake (before and 3 hours after drug intake). The results of thrombelastometry/-graphy and multiple platelet function analyzer will be compared directly with the concentrations determined by plasma concentration assays.
|Ages Eligible for Study:
||18 Years and older
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
Primary Care Clinic. Patients with non-valvular atrial fibrillation who receive Dabigatran or Rivaroxaban for prevention of stroke and systemic embolism.
- Patients receiving Dabigatran or Rivaroxaban
- Adults > 18 years
- Patients receiving concomittantly inhibitors of platelet function
- Renal insufficiency (Creatinine > 1,5 mg/dl), Urea > 80 mg/dl)
- Hepatic Dysfunction (AST > 30 U/l, ALT > 30 U/l)
