Introduction:

To characterize the population of patients hospitalized for acute heart failure with an ejection fraction of less than 50% in the Departmental Hospital of Villavicencio.

Materials and method:

This is a descriptive retrospective cohort study of patients hospitalized for acute heart failure with an ejection fraction (LVEF) of less than 50% between January 1, 2020, and December 31, 2021.

Results:

A total of 206 participants were included, with a median age of 70 years, of the participants, 71.8% were men, the most frequent comorbidities were hypertension (76.2%), coronary disease (47.1%), and diabetes (32%). The main etiologies of heart failure were ischemic (62.1%) and hypertensive (27.2%), with 6.8% attributed to Chagas disease. The most common causes of decompensation were acute coronary syndrome (39.3%) and poor adherence to treatment (25.7%). The median hospital stay was 7.5 days, and the hospital mortality rate was 14.6%, acute coronary syndrome was the leading cause of death (56.7%). A high requirement for intensive care unit (ICU) management was observed (20.4%), which was higher in patients with slightly reduced LVEF compared to those with reduced LVEF (35.7% vs. 18%, RR = 1.98, p = 0.03), however, the mortality rate was similar between both groups (17.9% vs. 14%, RR = 1.32, p = 0.54).

Conclusions:

It was found a high prevalence of ischemic heart disease, along with a high requirement for ICU management and high in-hospital mortality.
