Introduction:

Hyponatremia is the most frequent electrolyte alteration in geriatric patients. There is evidence that associates it with a worse prognosis in patients with heart failure.

Objective:

To describe geriatric patients admitted with hyponatremia on admission and heart failure.

Method:

A descriptive, longitudinal and prospective study was carried out in 2018 at Calixto García Surgical Clinical University Hospital, including 260 patients with heart failure and hyponatremia on admission. For the statistical analysis of the data, they reused the chi-square test and the multivariate analysis of ANOVA for the association between variables.

Results:

The mean age was 72.6 ± 8.2, women predominated (55.0%). Prevalence was observed in the Charlson score 3-4 (33.8%), the ejection fraction preserved (70.8%); functional class III was 33.8%; 43.1% stayed less than 6 days and 51.9% of the sample studied died. They were significantly associated with mortality at discharge, the comorbidity index and functional class III-IV, p <0.05.

Conclusions:

There is a high mortality in geriatric patients hospitalized for heart failure and hyponatremia on admission associated with the presence of comorbidity and the classification of heart failure.
