Malnutrition is associated with poor prognosis in heart failure

May 11, 2018

(HealthDay)—Patients with heart failure frequently have malnutrition, which is associated with increased mortality, according to a study published online May 9 in JACC: Heart Failure.

Shirley Sze, M.B.B.S., from Hull York Medical School in the United Kingdom, and colleagues applied the geriatric nutritional risk index (GNRI), controlling (CONUT) score, and prognostic nutritional index (PNI) to 550,000 patients referred with suspected heart failure to examine the prognostic consequences of .

The researchers confirmed heart failure in 3,386 of 4,021 patients enrolled. Overall, 6.7, 10.0, and 7.5 percent of patients were moderately or severely malnourished using scores for GNRI ≤91, CONUT >4, and PNI ≤38, respectively; 57 percent of participants were at least mildly malnourished by one or more scores. Overall, 51 percent of patients died during a median follow-up of 1,573 days. One-year mortality was 28, 41, and 36 percent for patients moderately or severely malnourished for CONUT, GNRI, and PNI, respectively, compared with 9 percent for those with mild malnutrition or normal nutritional status. One-year survival was predicted by a model including age, urea, and log-N-terminal pro-B-type natriuretic peptide (C-statistic, 0.719); additional of nutritional indices, but not , slightly improved prediction (C-statistic, up to 0.724).

"Malnutrition is common among outpatients with and is strongly related to increased mortality," the authors write.
