Abstract

Atrial fibrillation (AF) is the most common arrhythmia. Its prevalence increases with age and increases the risk of stroke and systemic embolism. Few data are currently available on the quality of life (QOL) of anticoagulated patients with the advent of direct oral anticoagulants (DOAC). Our study aims to describe levels of QOL in elderly patients with AF receiving oral anticoagulants and compare QOL of patients treated with vitamin K antagonists (VKA) and DOAC. This prospective study included patients of 65 years and over, receiving anticoagulants for AF (VKA or DOAC) from general practice (n=70) or cardiac practice (n=30). The patients completed a self-administered questionnaire that included demographic, geriatric data and a QOL standardized scale: the anti-clot treatment scale (ACTS) 17 items exploring two dimensions "Burdens" and "Benefits". Eighty-nine patients were enrolled: 61 were taking VKA and 28 taking DOAC. Our two groups were comparable for all demographic and clinical characteristics studied. Our patients' mean scores were 48.6±12.1 on Burdens and 9.7±3.8 on Benefits. Burdens and Benefits scores were significantly better for patients treated with DOAC compared to patients with VKA (p<0.0001 and p<0.01, respective...Continue Reading

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Acute Stroke

A stroke occurs when blood supply to the brain is interrupted depriving the brain of oxygen and nutrients. This feed focuses cerebrovascular accidents including ischemic and paralytic stroke.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
