Insights
Heart failure with midrange ejection fraction (HFmrEF) represents a distinct patient group. Further research is crucial to understand HFmrEF
Area of Science:
- Cardiology
- Heart Failure Research
- Clinical Medicine
Background:
- Heart failure with midrange ejection fraction (HFmrEF) is a recently defined category.
- Existing research predominantly focuses on heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF).
- A knowledge gap exists for patients with left ventricular ejection fraction between 40-49%.
Purpose of the Study:
- To provide an overview of current data on HFmrEF.
- To identify gaps in knowledge regarding HFmrEF.
- To highlight the need for extensive research in this area.
Main Methods:
- Literature review of existing studies on HFmrEF.
- Analysis of clinical, structural, and functional characteristics.
- Assessment of outcomes in comparison to HFrEF and HFpEF.
Main Results:
- HFmrEF patients exhibit distinct intermediate characteristics compared to HFrEF and HFpEF.
- Current findings on HFmrEF are often contradictory.
- Significant gaps remain in understanding hemodynamic characteristics, long-term prognosis, and optimal therapies for HFmrEF.
Conclusions:
- HFmrEF represents a significant yet understudied population within heart failure.
- More research is essential to elucidate the specific profile and management of HFmrEF.
- Addressing this knowledge gap is critical for improving patient care.
Abstract:
Heart failure with midrange ejection fraction (HFmrEF) is a new category of heart failure (HF), inbetween HF with reduced ejection fraction (HFrEF) and HF with preserved ejection fraction (HFpEF). Previous studies were mainly conducted in HFrEF patients having a left ventricle ejection fraction (LVEF) lower than 35-40%. Later on, HFpEF captured the spot-light of the research field, and studies focused on patients with HF symptoms, but with a LVEF exceeding 50%. Consequently, a gap of knowledge comprising the LVEF between 40 and 49% has arisen. Current studies focusing on patients with HFmrEF are arguing the same conclusions or even having contradictory findings. HFmrEF has a prevalence of 10-20% of HF patients. HFmrEF has distinct, but intermediate clinical, structural and functional characteristics, as well as intermediate outcomes in comparison with HFrEF and HFpEF. However, there is still a large gap in evidence regarding detailed hemodynamic characteristics, long-term follow-up and optimal therapeutic options for these patients. Extensive research was recommended in order to improve knowledge about this "gray area" of patients with HF. Therefore, we aimed to provide an over-view of the existing and lacking data regarding patients with HFmrEF.
