CALVACHI PRIETO, Paola et al. Clinical characteristics of acute heart failure patients according to left ventricular function. Rev. Colomb. Cardiol. [online]. 2018, vol.25, n.1, pp.7-12. ISSN 0120-5633.


Acute heart failure is the most frequent cause of hospital admissions in patients over 65 years-old. Only few descriptive studies have been published on the Colombian population. The aim is to carry out an observational study that determines the clinical characteristics of patients with acute heart failure in a hospital in Colombia.


An observational, cross-sectional study was conducted using information from clinical records of patients diagnosed with acute heart failure between 2011 and 2015 in our Foundation. These data were collected using the Colombian Registry of Cardiovascular Disease (RECODEC).


The analysis was performed on the data from 550 patients, with a median age of 77 years. The univariate analysis showed a higher prevalence of the disease in men (55%), and a significant association with hypertension (78.2%), coronary disease (31.8%), and atrial fibrillation (29.6%). In the bivariate analysis, the patients were divided into three groups according to their left ventricular ejection fraction: decreased (<40%), restricted (41%-49%), and preserved (> 50%), with the preserved ejection fraction being the most prevalent. The main outcomes were mortality (8.4%) and the occurrence of arrhythmias (22.5%).


It is important to take into account that the analysis of the RECODEC database has been used to evaluate the epidemiological and clinical aspects of cardiovascular disease. However, there is a need to create registries at a national level in order to analyse the general characteristics of the Colombian population.
