Abstract

In Spain, more than 80% of patients with atrial fibrillation (AF) receive oral anticoagulant therapy (OAT), and 72% of these patients are followed up in the Primary Care (PC) setting. Recent studies have shown that there is insufficient control of patients on OAT. The objective of the present study was to obtain more detailed information on the state of control of patients on treatment with vitaminK antagonist (VKA) oral anticoagulants (OAC), on the diseases for which the therapy was indicated and on concomitant diseases. This was a retrospective, cross-sectional, observational study with the participation of patients from a single health area included in an OAT programme throughout 2014. In patients on treatment with OAC, International Normalised Ratio (INR) control was considered insufficient when the percentage time in therapeutic range (TTR) was below 65% during an evaluation period of at least 6months. A total of 368 patients were included in the study, where the most frequent indication for oral anticoagulation was non-valvular AF. A total of 5,128 INR controls were performed, of which 2,359 (46%) were outside the therapeutic range, and 2,769 (54%) were within range. The risk of thromboembolism was very high in 91% of pat...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.

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.

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.
