Heart failure (HF) is a syndrome, whose advanced forms have a poor prognosis, which is aggravated by the presence of comorbidities.


We assessed the impact of infection in patients with decompensated HF admitted to a tertiary university-affiliated hospital in the city of São Paulo.


This study assessed 260 patients consecutively admitted to our unit because of decompensated HF. The presence of infection and other morbidities was assessed, as were in-hospital mortality and outcome after discharge. The chance of death was estimated by univariate logistic regression analysis of the variables studied. The significance level adopted was P < 0.05.


Of the patients studied, 54.2% were of the male sex, and the mean age ± SD was 66.1 ± 12.7 years. During hospitalization, 119 patients (45.8%) had infection: 88 (33.8%) being diagnosed with pulmonary infection and 39 patients (15.0%), with urinary infection. During hospitalization, 56 patients (21.5%) died, and, after discharge, 36 patients (17.6%). During hospitalization, 26.9% of the patients with infection died vs 17% of those without infection (p = 0.05). However, after discharge, mortality was lower in the group that had infection: 11.5% vs 22.2% (p = 0.046).


Infection is a frequent morbidity among patients with HF admitted for compensation of the condition, and those with infection show higher in-hospital mortality. However, those patients who initially had infection and survived had a better outcome after discharge.
