Análise das internações hospitalares e taxa de mortalidade por insuficiência cardíaca no Brasil: estudo longitudinal

Abstract

Introduction: Heart failure (HF) affects between 1 and 2% of the adult population and in Brazil it represented the main cause of hospitalization among cardiovascular diseases between 2008 and 2017. Objectives: To analyze the number of hospital admissions, in-hospital deaths and rate of mortality due to HF in adults according to sex, race, age group and federative region in the period between 2008 and 2019 in Brazil. Methods: This is a descriptive longitudinal study, with a quantitative approach, using data extracted from the SIH/SUS, referring to the number of hospital admissions, number of deaths, mortality rate, year of processing, total and average value of admissions and average of days of hospital stay according to sex, race, age group and federative region. Data were analyzed using GraphPad Prism and the established significance level was α<0.05. Results: 2,766,615 hospitalizations for HF were observed in Brazil between 2008 and 2019, a reduction of 25.72% (p<0.0006) when comparing the period, in addition to 272,051 hospital deaths. There was also a 3.8% increase in the number of deaths when comparing 2008 and 2019 (p=0.331). The in-hospital mortality rate due to HF was 9.83, the average length of stay was 6.9 days and the average value was 1,317.84 reais per hospital stay. Conclusion: Although a reduction in the number of hospitalizations was observed, an increase in the mortality rate was observed in the same period, mainly in individuals >60 years old and residents of the Southeast region. Such findings should be considered when implementing HF prevention, care and control strategies.
