Frequency of Hyperthyroidism in Atrial Fibrillation

Abstract

Introduction: Incidence of atrial fibrillation is increasing globally, and hyperthyroidism is a known precipitating factor for atrial fibrillation (AF). There are few studies that shown the frequency hyperthyroidism in patients presenting with AF, so we conducted this study. Methods and results: All patients presenting with atrial fibrillation in outpatient department of medicine and NICVD Nawabshah were included. We enrolled 96 patients with atrial fibrillation, out of these 61.5% were males and 38.5% females. Mean age of the subjects was (51.89 ±13.243) years. Mean age of females (45.81± 12.86). Most of subjects were in 41-60 years (52.1%) age group. The hyperthyroidism found in 16.7%. patients presenting with AF. We found statistically significant with presence or absence of thyroid antibodies. Conclusion: We found the hyperthyroidism common in patients presenting AF and need more multicenter studies to check the exact prevalence. All patients presenting with AF, the routine thyroid functions tests recommended.
