Abstract
Objectives: To investigate the relation between serum Vitamin D (Vit-D) levels and the success rate of cardioversion for atrial fibrillation (AF). To examine the association between Vit-D level and successful cardioversion. This study also describes the general characteristics of patients with successful cardioversion. Materials and Methods: In this retrospective study, patients with AF who were treated using electrical cardioversion at King Abdulaziz Cardiovascular Center (KACC) between 2010 and 2021 were included. The information on demographic and clinical characteristics as well as outcome variables was collected. Results: Of 100 patients who were admitted to KACC during the study period, 63% were females and 9% were diagnosed with Vit-D deficiency. Furthermore, 66% of patients had successful cardioversion. Moreover, no significant difference in Vit-D deficiency was observed between patients who had successful cardioversion and those with unsuccessful outcomes (P = 0.485). Conclusions: There is no association between serum Vit-D levels and the success rate of cardioversion in patients with AF. However, further studies are needed for more conclusive evidence.
