Impact of malnutrition in the embolic–haemorrhagic trade-off of elderly patients with atrial fibrillation

Abstract Aims Nutrition is an important determinant of health above the age of 80 years. Malnutrition in the elderly is often underdiagnosed. The aim of this study was to report the prevalence and prognostic value of malnutrition in patients ≥80 years old with atrial fibrillation (AF) with and without anticoagulant therapy. Methods and results We assessed the nutritional status of 4724 octogenarian patients with diagnoses of AF in a single centre from Spain between 2014 and 2017 with the CONUT score. Malnutrition was confirmed in 2036 patients (43.1%). Anticoagulation prescription was more frequent in patients with good nutrition than in those malnourished (79.5% vs. 71.7%, P
