vitamin d deficiency and atrial fibrillation: a cross sectional single center study

Background: atrial fibrillation (af) augments the risk of stroke by 4-5 times. vitamin d is pivotal in numerous metabolic pathways. a handful of studies have explored the correlation between vitamin d deficiency (vdd) and af outcomes. hence, the authors sought to assess the relationship between vdd and af outcomes.methods: from december 2021 to february 2023, 190 patients with af were incorporated into the authors’ study. given the seasonal fluctuation of vitamin d levels, these levels were examined from the start of december until the end of march.results: the final analysis comprised 190 patients (55.8% male) with an average age of 46.22±15.03. vitamin d deficiency, insufficiency, and sufficiency were noted in 77 (40.5%), 46 (24.2%), and 67 (35.3%) patients, respectively. fatigue and syncope were significantly more prevalent in the vdd group than in other groups. three-vessel disease was more frequent in the vdd group (p-value=0.04). mortality was more prevalent in patients with vdd (6.31%) compared to the vdi (2.10%) and vds (0.05%) groups (p = 0.03). successful cardioversion was significantly more prevalent in the vds group (p = 0.03).conclusion: a sufficient level of vitamin d was linked with a better response to cardioversion. however, low vitamin d levels are correlated with higher mortality in af patients.
