Heart Failure with Mildly Reduced Ejection Fraction-A Phenotype Waiting to Be Explored

Area of Science:

• Cardiology
• Clinical Medicine
• Heart Failure Research

Background:

• Heart failure (HF) is a major global health concern with high hospitalization and mortality rates.
• Left ventricular ejection fraction (EF) is key for HF diagnosis and prognosis, classifying it into HFpEF, HFrEF, and HFmrEF.
• HFmrEF, a distinct HF subtype, presents management challenges due to its heterogeneous nature.

Purpose of the Study:

• To examine the characteristics of HFmrEF.
• To discuss the rationale behind re-classifying HFmrEF.
• To review current treatment strategies for HFmrEF.

Main Methods:

• Literature review and analysis of large-scale studies.
• Examination of biomarker utility for phenotyping HFmrEF.
• Discussion of individualized treatment approaches.

Main Results:

• HFmrEF exhibits unique attributes distinct from HFpEF and HFrEF.
• Predictors of clinical outcomes and treatment responses in HFmrEF require further large-scale investigation.
• Biomarker-guided phenotyping may reveal novel therapeutic targets.

Conclusions:

• HFmrEF requires specific attention due to its complex presentation and management challenges.
• Individualized treatment strategies are essential for optimizing care in HFmrEF patients.
• Further research is needed to refine management and identify new therapeutic avenues for HFmrEF.
