BACKGROUND Clinical studies from other countries show that self-management of warfarin therapy may reduce the risk of mortality, thromboembolism and complications when compared to conventional therapy. The purpose of this study was to train patients in self-management and compare the results with conventional therapy in Norway. METHOD A total of 23 patients who had previously been given conve...

Calciphylaxis is a challenging complication of end-stage renal disease, with an unknown underlying mechanism. Several risk factors have been identified, such as hyperphosphatemia, hypercalcemia, hyperparathyroidism, low serum albumin levels, and history of warfarin therapy. This article presents a case of calciphylaxis provoked by reintroduction of warfarin therapy, introducing the possibility ...

BACKGROUND Patients with acute ischemic syndromes (AIS) suffer high rates of recurrent ischemic events despite aspirin treatment. Long-term therapy with oral anticoagulants in addition to aspirin may reduce this risk. We studied the effects of long-term warfarin at 2 intensities in patients with AIS without ST elevation in 2 consecutive randomized controlled studies. METHODS AND RESULTS In ph...

Atrial fibrillation is an increasingly common arrhythmia, now said to stand at epidemic proportion in Western societies: .2.3 million people in the USA and .4.5 million people in Western Europe. It is an expression of underlying heart disease and a threat to life and living. In particular it is associated with 4.5-fold risk of stroke, predominantly ischaemic in nature, largely due to embolizati...

BACKGROUND The cytochrome P450 CYP2C9 is responsible for the metabolism of S-warfarin. Two known allelic variants CYP2C9*2 and CYP2C9*3 differ from the wild type CYP2C9*1 by a single aminoacid substitution in each case. The allelic variants are associated with impaired hydroxylation of S-warfarin in in-vitro expression systems. We have studied the effect of CYP2C9 polymorphism on the in-vivo wa...

Atrial fibrillation (AF) is considered as one of the most common cardiac arrhythmias worldwide and always associated with a significantly increased risk stroke thromboembolism. VKAs (Warfarin & Acenocoumarol) are highly effective in reducing patients AF, but bleeding issues disutility sparked development direct oral anticoagulants (DOACs) or NOACs (Novel anticoagulants). These drugs, offer ...

The effect of concomitantly administered clopidogrel on anti-coagulation status was investigated in patients receiving long-term warfarin therapy. Forty-three patients with non-valvular atrial fibrillation who were receiving long-term warfarin and had a stable international normalized ratio (INR) between 2 and 3 were randomly assigned to clopidogrel 75 mg daily or placebo for 8 days (Days 1-8)....

OBJECTIVES The clinical effect of combined warfarin and antiplatelet therapy on the incidence of stroke and postoperative complications after mitral (plus aortic) valve replacement was studied and compared with that observed with warfarin therapy alone. BACKGROUND It has been reported that combined warfarin and antiplatelet therapy may be effective but may be associated with an increased hemo...

  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...
