AIMS Atrial fibrillation patients with prior embolism have a high risk of vascular events in spite of anticoagulant therapy and elderly patients carry an additional risk. We analysed and compared vascular events-rate between older and younger than 75 years atrial fibrillation patients randomized to anticoagulant-alone or combined antiplatelet plus moderate-level anticoagulant therapy. METHODS...

A patient with a circulating lupus anticoagulant in the absence of systemic lupus erythematosus developed recurrent deep venous thromboses and pulmonary emboli. Pulmonary emboli recurred despite prolonged oral anticoagulant therapy and resulted in fatal pulmonary arterial hypertension. Extended anticoagulant therapy alone may not prevent recurrent thromboembolism in patients with a lupus antico...

BACKGROUND The study aimed to evaluate the prognosis for patients with colorectal cancer who underwent surgery while receiving antithrombotic therapy (ATT) across all disease stages and for patients at disease stages 0-III. METHODS This retrospective cohort study included 710 Japanese patients who underwent surgery for colorectal cancer between January 2009 and November 2015 at our institutio...

  Atrial fibrillation (AF) is associated with inflammatory and hypercoagulability state. Previous studies evaluated the safety and efficacy of dabigatran and warfarin in prevention of thrombothic complications. This study was intended to assess the influence of these drugs on hemostatic and inflammatory markers among patient underwent pulmonary vein ablation.   A total of 100 patients with AF w...

Oral anticoagulant therapy, which is used for prophylaxis and management of thrombotic disorders, causes similar reductions in plasma levels of vitamin K-dependent procoagulant and anticoagulant clotting factor zymogens. When we measured levels of circulating activated protein C, a physiologically important anticoagulant and anti-inflammatory agent, in patients on oral anticoagulant therapy, th...

Among 52 cases of prosthetic valve endocarditis, adequate anticoagulant therapy was administered in 38 and discontinued or given in subtherapeutic dosage in 14. Our data suggest that anticoagulant therapy does not appreciably increase morbidity or mortality in patients with prosthetic valve endocarditis. On the contrary, in our patients the incidence of major clinical CNS (central nervous syste...
