Iron deficiency and hematinic deficiencies in atrial fibrillation: A new insight into comorbidities

Objective: Iron deficiency (ID) is the most common nutritional deficiency, and iron metabolism becomes further deteriorated in the presence of certain conditions, such as heart failure (HF). Atrial fibrillation (AF) has many similarities to HF, including a chronic inflammatory pathophysiology; however, the prevalence of ID and other hematinic deficiencies in AF patients have not been determined. Methods: In this study, the prevalence of iron (serum ferritin
