Characteristics, treatment and prognosis of patients with chronic heart failure according to ejection fraction. Results of an Ecuadorian registry.
Background: In Ecuador, there are few data about the clinical behaviour of heart failure (HF). This study aims to analyse the clinical characteristics, treatment and prognosis according to the current classification based on left ventricular ejection fraction (EF).
Methods: A retrospective observational study was carried out in patients with chronic HF from the 'Los Ceibos' registry during the period January 2017-December 2022. Patients were classified into HF with preserved EF (HFpEF) [EF ≥ 50%], HF with mildly reduced EF (HFmrEF) [EF:41-49%], and HF with reduced (HFrEF) [EF ≤ 40%]. The patients were followed up for a mean time of 2.28 (IQR 1.25-3.49) years.
Results: A total of 711 patients were included, 333 (46.8%) with HFrEF, 109 patients (15.3%) with HFmrEF and 269 patients (37.8%) with HFpEF. The average age was 69.8 ± 13.1 years, 31.4% were women. The main comorbidity was arterial hypertension (92.7%). Angiotensin-converting enzyme inhibitors or angiotensin receptor blockers were used in 74.5%, beta-blockers in 82.3%, and mineralocorticoid receptor antagonists in 51.3%. 58.3% of patients with HFrEF received three drugs of the so-called foundational quadruple therapy. A lower all-cause (24.5%) and cardiovascular mortality rate (11,2%) was observed in the HFpEF group compared to HFmrEF (47.4% and 25,7%) and HFrEF (45.3% and 25,8%), p < 0.001.
Conclusions: In the 'Los Ceibos' registry, a higher prevalence of HFrEF was observed. The main comorbidity was HTN. Half of the patients with HFrEF received three drugs of the foundational therapy. At four years of follow-up, lower all-cause and cardiovascular mortality rate was observed in the HFpEF group.
