BACKGROUND AND OBJECTIVES: Obesity is a risk factor for @entity712 ( @entity712 ). @entity2121 , it has been described that body mass index (BMI) is inversely associated with mortality. The aim of this study was to analyse the relationship between BMI and mortality in a cohort of @entity1 with @entity712 . @entity1 AND METHODS: All @entity1 included in the RICA Registry between March 2008 and September 2009 were analysed. RICA is a multicenter, prospective cohort study that includes @entity1 admitted for decompensated @entity712 in Spanish Internal Medicine Services. @entity1 were divided according to the WHO body weight categories. RESULTS: 712 @entity1 were included; 54% were @entity1 and mean age was 77.3 years. @entity101 was the most common etiology of @entity712 with some differences according to BMI categories, being @entity340 more frequent among @entity28 and overweight @entity1 and @entity63 @entity712 among normal weight @entity1 . Mean left ventricle ejection fraction was 50.2% and it was higher among higher BMI categories. Natriuretic peptide levels were significantly lower among higher BMI categories (P<.05). Overall mortality after one-year of follow-up was 13.9% and it was significantly lower among higher BMI categories: normal BMI 20.4%, overweight 14.7% and @entity28 8.5% (P<.01). In the multivariate analysis, overweight was significantly and independently associated with an increased mortality risk in comparison with @entity28 : RR 3.05 (IC95% 1.24-7.54). CONCLUSIONS: An increase in BMI was associated with lower levels of natriuretic peptides and lower mortality.
