Abstract
Heart failure with preserved ejection fraction (HFpEF) is the most common condition of heart failure (HF) in patients over 65 years of age and is associated with high morbidity and mortality. Epidemiological data on this condition are still scarce in Brazil and these data are relevant for a better understanding of the impact and unmet needs in HFpEF and for the planning of actions to improve prevention, diagnosis, and treatment of this disease.
The objective of the study was to identify evidence on the epidemiology and clinical characteristics of Brazilian patients with HFpEF.
We systematically reviewed observational and clinical studies evaluating epidemiological and clinical data of Brazilian patients with HFpEF in the Pubmed/MEDLINE and LILACS databases, following PRISMA guidelines.
The prevalence of HFpEF in patients with confirmed HF ranged from 28.2 to 59.0% in the outpatient setting and from 20.0% to 53.1% in the hospital setting. Among patients with suspected HF, the prevalence of patients with LVEF>50% ranged from 29.0 to 37.6%. The most frequently reported comorbidities were systemic arterial hypertension and diabetes, with a prevalence of 57.4 to 100.0% in studies involving only patients with HFpEF, and from 10.2 to 49.1% in studies on patients with HF with normal ejection fraction (n = 14). Data on mortality and hospitalization rates were scarce.
Despite few and heterogeneous data on the prevalence of HFpEF in Brazil, the prevalence of this condition in primary care patients and in hospitalized patients was relatively high.
