Characterization of Malnutrition in Atrial Functional Mitral Regurgitation.

ABSTRACT:

Background

In this study we sought to characterize the prevalence, clinical characteristics, and outcomes of malnutrition in patients with atrial functional mitral regurgitation (AFMR).

Methods

This multicentre, observational study included 802 patients diagnosed with AFMR. The Geriatric Nutritional Risk Index (GNRI) was used as a nutritional risk metric. Patients were divided into 4 groups on the basis of the GNRI: normal (> 98; n = 342), mild nutritional risk (92-98; n = 196), moderate risk (82 to < 92; n = 166), and severe risk (< 82; n = 98). The primary outcome was a composite of heart failure admission and all-cause death.

Results

At least mild nutrition risk (GNRI ≤ 98) was present in 57% of patients with AFMR. Patients with lower GN
