Brazilian Evidence Reinforces the Applicability of the H2FPEF and HFA-PEFF Scores in HFpEF
This Short Editorial is referred by the Research article "Prognostic Applications of Current Clinical Scores in Heart Failure with Preserved Ejection Fraction: A Prospective Cohort Study".
Heart failure with preserved ejection fraction (HFpEF) remains a diagnostic challenge in modern cardiology. Representing approximately half of all heart failure cases, this condition presents with complex pathophysiology, often subjective diagnostic criteria, and more limited therapeutic options., In this context, the use of diagnostic scoring systems, such as H2FPEF and HFA-PEFF, has gained importance, providing clinicians with standardized and evidence-based tools to guide both diagnosis and risk stratification.,
A prospective study conducted at a Brazilian tertiary hospital provides relevant data on the applicability of these scores in our population. Conducted between March 2019 and December 2021, the study included 103 patients diagnosed with HFpEF, who were followed for approximately 2.4 years. In addition to clinical and echocardiographic characterization, all patients underwent exercise testing, and both the H2FPEF and HFA-PEFF scores were calculated. Patients were then categorized into intermediate- and high-probability groups according to the score points obtained and followed for the composite outcome of all-cause mortality and heart failure hospitalizations.
