The impact of , and gene polymorphisms on apixaban trough concentration and bleeding risk in patients with atrial fibrillation.

Objectives: Apixaban, a direct oral anticoagulant, is increasingly used worldwide for the treatment and prevention of venous thromboembolism and ischemic stroke in patients with nonvalvular atrial fibrillation (AF). Obviously, one of the ways to enhance effectiveness and safety of drug therapy is a personalized approach to therapy, which involves pharmacogenetic and pharmacokinetic tests. The study aims to investigate the effect of , and polymorphisms on the pharmacokinetics of apixaban and the risk of bleeding.

Factors Affecting Trough Plasma Dabigatran Concentrations in Patients with Atrial Fibrillation and Chronic Kidney Disease.

Introduction: Dabigatran is effective and widely used to prevent ischemic stroke and systemic embolism (SE) in patients with atrial fibrillation (AF). Chronic kidney disease (CKD) also has implications for choice of any medications, as it alters pharmacokinetic parameters of drugs.

Aim: To evaluate trough plasma dabigatran concentration (DTPC) and to analyse potential factors affecting these values in patients with AF and CKD.

Effect of CES1 and ABCB1 genotypes on the pharmacokinetics and clinical outcomes of dabigatran etexilate in patients with atrial fibrillation and chronic kidney disease.

Background Despite the well-studied safety profile of dabigatran, its interactions with genetic polymorphism parameters are poorly understood, especially in patients with moderate chronic kidney disease (CKD). The study assessed whether genetic factors can contribute to CKD and alter dabigatran concentration. Methods Patients with atrial fibrillation (AF) and stage 3 CKD treated with dabigatran 110 or 150 mg have been included in the study.

Impact of atrial fibrillation on the rate of mild cognitive impairment in the elderly.

Mild cognitive impairment (MCI) in patients with cardiovascular risks is a transitional state to vascular dementia but which still has a possibility of being managed. The objectives of this study were to assess the impact of atrial fibrillation (AF) on cognitive performances in the elderly in comparison with similar cardiovascular risks. One hundred unselected patients were included in AF+ and AF- groups.
