Frequency of atrial fibrillation and factors related to its development in dialysis patients

353 Prevalence of Chronic Atrial Fibrillation in Dialysis Patients

“…As such, previously-reported findings of associations between various patient factors, at least those identified upon dialysis initiation, and chronic AF can be robustly quantified. As expected, we echoed the finding of the association of age with AF reported by Wizemann et al in the DOPPS database 8 , Abbott et al (in a univariate analysis) in Dialysis Morbidity and Mortality (DMMS) Wave II study 18 , Vasquez et al in their small but well-studied incident dialysis cohort 11 , and others 5,7 . Both Abbott et al and Wizemann et al also found Caucasian race to be associated with AF 8,18 .…”

“…The DOPPS investigators also found BMI to be significantly correlated in direct fashion with preexisting AF 8 . Notably, the role of sex in dialysis patients with AF remains unclear; while some investigators report sex to be unassociated with either incident or prevalent AF 5,7,8 , and others that female sex is the risk factor 11 , our finding of an association of male sex with chronic AF is reflective of findings in the general population 14 . As anticipated, CAD and CHF emerged as comorbidity factors associated with AF in our study.…”

“…Introduction Atrial fibrillation (AF) is common in end stage renal disease (ESRD) patients on maintenance dialysis, [1][2][3][4][5][6][7][8][9] and is independently associated with mortality in the general 10 and dialysis 8,11 populations. Recent studies examining the epidemiology of AF in cohorts drawn from a large dialysis-provider organization 12 and from the Dialysis Outcomes and Practice…”

Electrocardiographic findings in chronic hemodialysis patients

“…Em estudo de Atar et al, 15 a prevalência de FA foi de 10,9% e de 13,6% em estudo espanhol com 190 pacientes em programa de hemodiálise e realizado por Vázquez et al. 16 O nosso estudo não foi desenhado para avaliar FA, que seguramente iria requerer a realização de ecocardiograma para determinar variáveis ecocardiográficas sabidamente associadas à FA e fomos estritamente rigorosos aos critérios eletrocardiográficos de definição de FA, distinguindo-a de ritmos como ritmo atrial migrató-rio e atrial ectópico que, em parte, poderia explicar a mais baixa prevalência de FA encontrada em nosso estudo.…”

The deleterious effects of arteriovenous fistula-creation on the cardiovascular system: a longitudinal magnetic resonance imaging study

“…30 Left atrial dilatation has previously been identified as an independent risk factor for the development of atrial fibrillation in ESRF and may contribute to the poor CV prognosis of patients with CKD. 31,32 Furthermore, whether through the predisposition to AF or as a marker of chronic LV diastolic impairment, recent evidence confirms an association between LA dilatation and increased mortality in ESRF patients with LV hypertrophy. [32][33][34] Our study would support the conclusion that changes in atrial dimension following AVF-creation may play a significant role in the promotion of atrial arrhythmia within the ESRF milieu.…”
