Epidemiology of decompensated heart failure in the city of Niterói: EPICA - Niterói Project.
OBJECTIVE
To compare the epidemiological and socioeconomic profiles, clinical features, etiology, length of hospitalization, and mortality of patients with decompensated heart failure admitted to public and private hospitals in the city of Niterói.


METHODS
We carried out a prospective, multicenter study (from July to September 2001) comprising all patients older than 18 years with the primary diagnosis of heart failure and admitted to hospitals in the city of Niterói, whose scores according to the Boston criteria were 8 or above. Proportions were compared using the chi-square and Fisher exact tests.


RESULTS
The sample comprised 203 patients as follows: 1) 98 patients from public hospitals: 50% were men, their mean age was 61.1+/-11.3 years, 65% were black, 57% had an income of 1 minimum wage or less, 56% were illiterate, 66% had ischemic heart disease, their mean length of hospitalization was 12.6 days, and the mortality rate adjusted for age was 5.23; 2) 105 patients from private hospitals: 49% were men, their mean age was 72+/-12.7 years, 20% were black, 58% had an income greater than 6 minimum wages, 11% were illiterate, 62% had ischemic heart disease, their mean length of hospitalization was 8 days, and the mortality rate adjusted for age was 2.94. The distribution of comorbidities and risk factors was similar among the patients of the 2 hospital systems, except for the smoking habit, which was more frequent among patients from public hospitals.


CONCLUSIONS
In addition to the socioeconomic asymmetries, the hospitalization length and the mortality rate adjusted for age were greater in patients in the public health system.
