AbstractDespite better diagnoses and treatments, heart failure (HF) is an important cause of death in Spain. The objective of this study is to describe the characteristics and treatment of a population with chronic HF classified according to the left ventricular ejection fraction (LVEF). Population-based observational cohort study in Primary Health Care. Catalonia, Spain, during 2014-2018. Adults with HF classified by the LVEF. Analysis of electronic health data registered in SIDIAP (Information System for Research in Primary Care). Demographics, LVEF, comorbidities, and use of drugs for HF. 10,130 patients were included; 18.9% with LVEF<40 (HFrEF), 15.9% with LVEF 40-49 (HFmEF) and 65.2% with LVEF≥50 (HFpEF), this last group with a higher proportion of women (57.5%) and higher mean age (80.2 years-old). People with HFmEF were similar to those with HFrEF in age, gender, comorbidities and treatment. The most frequent comorbidities were hypertension (78.3%), dyslipidaemia (54%) and atrial fibrillation (41.5%). The most frequent pharmacological treatments were β blockers with differences according to the LVEF [HFrEF 1515 (79.2%), HFmEF 1142 (70.8%) and HFpEF 3371 (51%)], followed by loop diuretics (65.7%). HF is a prevalent disease. Having information on LVEF could guide its pharmacological management. The HF population has persistent cardiovascular risk factors and habits. Treatment and population characteristics of patients with HFmEF are similar to those with HFrEF.Copyright © 2022 The Author(s). Publicado por Elsevier España, S.L.U. All rights reserved.
