FIGUEREDO MARTINEZ, Hugo Javier et al. Causes of death in adult patients with heart failure admitted to the National Hospital in the period 2017-2021. Rev. virtual Soc. Parag. Med. Int. [online]. 2022, vol.9, n.1, pp.81-89. ISSN 2312-3893.


Heart failure presents a high in-hospital and after discharge mortality, being a frequent cause of hospital readmission due to cardiac decompensation.


To determine the causes of death in adult patients with heart failure admitted to the National Hospital, Itauguá, Paraguay, in the period 2017 - 2021.


Retrospective descriptive observational cross-sectional study, which included 103 adult men and women with heart failure.


The mean age was 60±14 years (27-92 years), most of the patients were men (54.37%), of urban origin (57.28%), with primary studies (65.05%), secondary (31.07%) and with comorbidities (99.03%). The main comorbidity was arterial hypertension (28.16%). The main intercurrent pathologies were pathologies of infectious cause (56.25%). The mean ejection fraction was 43±11% (17-68%). The most frequent cardiac pathology was hypertensive heart disease (53.40%) followed by ischemic heart disease (35.92%). The mean BNP was 1823 pg/dL. Most of the patients had a decreased ejection fraction (70.87%) followed by a preserved one (29.13%). Mortality was 41.7% and the main cause of death was extracardiac (62.79%) with infectious pathologies as the most common (44.44%). When analyzing the factors related to mortality, it was found that age ≥ 60 years and presenting intercurrent pathology was related to mortality (p<0.05).


Mortality was 42% and the main cause of death was non-cardiac (62.7%), with intercurrent pathologies caused by infection being the most frequent. The predictors of mortality were age equal to or greater than 60 years and the presence of intercurrent pathologies (p <0.05).
