Burden of Mild (<13 g/dl) Anemia in Patients With Atrial Fibrillation (A Report from a Multicenter Registry With Patient-Reported Outcomes)

The prognostic impact of anemia, especially mild anemia, in atrial fibrillation (AF) remains unclear. We examined clinical burdens of mild anemia on the quality of life (QoL) and clinical outcomes of 1,677 AF patients. Patients were divided into a non-anemia (hemoglobin [Hb] ≥13 g/dl for men and Hb ≥12 g/dl for women) and a mild anemia group (10≤ Hb
