Rivaroxaban - Percutaneous Coronary Intervention

We investigated in-vitro the management of intraprocedural anticoagulation in patients requiring immediate percutaneous coronary intervention(PCI) while using regular direct oral anticoagulants(DOACs). Twenty-five patients taking 20mg of rivaroxaban once daily comprised the study group, while five healthy volunteers included the control group. In study group, a beginning(24-hours after the last rivaroxaban dose) examination was performed. Then, the effects of basal and four different anticoagulant doses(50IU/kg unfractionated heparin(UFH), 100IU/kg UFH, 0.5mg/kg enoxaparin, and 1mg/kg enoxaparin) on coagulation parameters were investigated at the 4th and 12th hours following rivaroxaban intake. Anticoagulant activity was assessed mainly by anti-factor Xa(anti-Xa) levels.
