Abstract
Heart failure with preserved ejection fraction (HFpEF) is a major healthcare problem with increasing prevalence. There has been a shift in HFpEF management towards early diagnosis and phenotype-specific targeted treatment. However, diagnosing HFpEF remains challenging due to a lack of universal criteria and patient heterogeneity. This review aims to provide a comprehensive assessment of the diagnostic workup of HFpEF, highlighting the role of echocardiography in HFpEF phenotyping.
