Registry of Patients Prescribed Anticoagulation


About this study

The purpose is to create a registry of patients at Mayo Clinic who are prescribed the new novel anticoagulation therapy with either rivaroxaban, dabigatran, apixaban, oe edoxaban to allow post marketing survelliance with particular attention to cancer patients treated with novel anticoalants which in marketing studies the patient numbers were small. We also want to compare efficacy and safety of novel anticoagulants to "traditional" anticoagulants such as warfarin and low molecular weight heparin (LMWH) and therefore to register patients treated with this type of anticoagulation to our registry too.
