Características clínico epidemiológicas de la insuficiencia cardíaca aguda en un hospital terciario de Lima, Perú

The objective of this study was to describe the clinical and epidemiological characteristics of acute heart failure (AHF) in 1,075 patients from a hospital in Lima, Peru. The average patient age was 74 years and 55% of study subjects were men. Moreover, 39% of patients in the sample had AHF with low ejection fraction, 15% had intermediate ejection fraction, and 46% had preserved ejection fraction. The most common comorbidities were hypertension (52.6%) and coronary disease (51%). Moreover, 29.2% of patients had previous hospitalizations due to AHF. The median hospital stay was 3 days. The rate of in-hospital mortality from all causes was 7.2%. Hospitalization was more common in elderly patients with multiple comorbidities. The low use of prescription drugs together with the high rate of previous hospitalizations may explain the high mortality rate reported in this study.
