Although low serum magnesium level is a relatively common problem in mixed medical/surgical intensive care units (ICUs), its association with new-onset atrial fibrillation (NOAF) has been studied to lesser extent. We aimed investigate the effect of levels on development NOAF critically ill patients admitted ICU. A total 110 eligible (45 female, 65 male) were included this case-control study. The age and sex-matched control group (n = 110) no from admission discharge or death. incidence was 2.4% between January 2013 June 2020. At onset matched time point, median lower than (0.84 [0.73-0.93] vs. 0.86 [0.79-0.97] mmol/L; p 0.025). 24.5% 27) 12.7% 14) had hypomagnesemia (p 0.037). Based Model 1, multivariable analysis demonstrated at point (OR: 0.07; 95%CI: 0.01-0.44; 0.004), acute kidney injury 1.88; 1.03-3.40; 0.039), APACHE II 1.04; 95% CI: 1.01-1.09; 0.046) as factors independently associated an increased risk NOAF. 2, 2.52; 1.19-5.36; 0.016) 0.043) In multivariate for hospital mortality, independent factor mortality 3.22; 1.69-6.13, p<0.001). increases mortality. Critically hypermagnesemia should be carefully evaluated
