Nutritional Risk and Mortality at One Year for Elderly Patients Hospitalized with Nonvalvular Atrial Fibrillation. Nonavasc Registry

To determine whether nutritional risk is associated with the mortality of elderly patients hospitalized with nonvalvular atrial fibrillation (NVAF). Prospective, multicenter cohort study. Internal medicine departments in Spain. Inpatients >75 years with NVAF. We measured the thrombotic and hemorrhagic risk at admission using the CHA2DS2-VASc and HAS-BLED scales, respectively, and the nutritional risk with the controlling nutritional status (CONUT) index. We established 4 degrees of nutritional risk: null (CONUT score 0-1 point), low (2-4 points), moderate (5-8 points) and high (9-12 points). We also conducted a 1-year follow-up. We included 449 patients, with a mean age of 85.2(5.2) years. The nutritional risk was null for 70(15.6%) patients, low for 206 45.9%), moderate for 152(33.8%) and high for 21(4.7%). At the end of one year, 177(39.4%) patients had died. The score on the CONUT index was higher for the deceased patients (4.6 vs. 3.6, p
