Abstract

Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia in clinical practice and is a common comorbidity in hemodialysis patients. AF contributes to cardiovascular complications; therefore, it is recommended to screen for AF in high-risk patients to prevent serious complications. As we currently lack a handy AF screening tool, the aim of this study was to assess the accuracy of a modified BP monitor (Omron M6), in detecting AF in hemodialysis patients. In a cross-sectional analysis conducted from October 2018 to February 2019, we enrolled all the hemodialysis patients, older than 18 years and maintained on hemodialysis for at least 3 months in four hemodialysis centers in Jordan. Logistic regression was used to predict the accuracy, while the R package (epiR) was used to determine the sensitivity and specificity of the Omron M6 in screening AF. A total of 227 patients participated in the study, with a median age of 57 years (42.8-67.3); among these, 44.5% were female. Of all the participants, 18 were detected with AF, which was confirmed by a 12-lead ECG. The prevalence of AF in our study was 7.9%, while the sensitivity, specificity and accuracy of the Omron M6 in detecting AF were calculated as 83.0% (95% CI, 59.0-96.0), 94.0% (95% CI, 90.0-97.0) and 93.4% (95% CI, 88.0-95.0) respectively. We concluded that Omron M6 has high sensitivity, specificity, and accuracy in screening AF among hemodialysis patients. However, further studies are required to ascertain and firmly establish this preliminary finding.
