Survival analysis of patients with heart failure in the Ecuadorian Sierra Norte between 2015 and 2020

Abstract:

Heart failure is one of the most important causes of morbidity and mortality worldwide. In developing countries there is little evidence regarding the prognosis of this disease. For this reason, the present study aims to establish the most important causes of heart failure and determine survival based on its etiology in patients diagnosed with heart failure in a second-level Ecuadorian General Hospital. A retrospective, single-center, prevalence study was conducted in 284 outpatients, diagnosed with heart failure, during the years 2015-2020. The differences between the subgroups were statistically analyzed using ANOVA tests. Survival analysis was performed using the actuarial method and Cox regression. The main cause of heart failure was hypertensive (55.5%), followed by ischemic etiology (20.8%). Survival analysis showed that overall 5-year survival was 17%, with an average life time of 3.46 years. The main cause of heart failure among patients was hypertensive and the 5-year overall survival is lower than that reported in other studies.
