The single-institution uncontrolled open-label trial is to optimize the anticoagulant therapy in the out-patient practice.~The study embraces patients who are advised to take the anticoagulant therapy for some reasons. The study has two phases - a retrospective part and a concurrent part. At the first phase, researchers analyze the compliance with the anticoagulant therapy in the real clinical practice. At the concurrent phase, researchers conduct a single-institution uncontrolled open-label trial to evaluate the effectiveness, safety of the anticoagulant therapy and compliance with it at the antithrombotic therapy control ward, and estimate the glomerular filtration rate in patients taking the anticoagulant therapy.
