The latest European Society of Cardiology Heart Failure (HF) guidelines define three types of HF according to the ejection fraction (EF): HF with reduced EF (HFrEF) when EF40%, HF with mid-range EF (HFmrEF), when EF 40-49%, and HF with preserved EF (HFpEF) when EF≥50%. The objective of this study was to analyse the characteristics and results of elderly patients hospitalised with HF according to the new classification using EF.A prospective study was carried out with 531 HF patients aged ≥75 years classified according to EF, and admitted in the geriatric wards of 6 hospitals in Spain. An analysis was performed on the demographic and clinical characteristics, as well as well as the morbidity and mortality at one year of follow-up.As regards EF, 17.1% had HFrEF, 10% had HFmrEF, and 72.9% had HFpEF. Patients with HFmrEF were more similar to those with HFrEF in terms of a younger age, predominance of men, and previous admission due to HF. This was also the case with the use of drugs for neurohormonal blockade. Patients with HFrEF (compared to those with HFmrEF and HFpEF), had higher mortality (35.2%, 24.5%, and 25.6%, respectively), more readmissions for HF (17.6%, 15.1%, and 14.5%, respectively), and more events (61.5%, 45.3%, and 52.5%, respectively), although there were no significant differences. There were also no differences observed in the survival analysis between the EF groups and the time-dependent outcome variables.In elderly patients hospitalised with HF, those classified as HFmrEF did not show any clear differences with respect to those with HFrEF or HFpEF. There were no differences in terms of morbidity and mortality. |
