Insights
Heart failure with preserved ejection fraction (HFpEF) is a complex condition. Recent trials show neurohormonal and SGLT2 inhibitors benefit HFpEF patients, particularly those with hypertension, regardless of ejection fraction.
Area of Science:
- Cardiology
- Internal Medicine
- Pharmacology
Background:
- Heart failure with preserved ejection fraction (HFpEF) affects about 50% of heart failure patients.
- HFpEF treatment has long been an unmet clinical need due to classification complexities and diverse underlying pathologies.
- Previous assumptions about absent neurohormonal overactivity in HFpEF patients with higher ejection fractions have been challenged.
Purpose of the Study:
- To re-evaluate the treatment strategies for HFpEF.
- To highlight the efficacy of neurohormonal and SGLT2 inhibitors across a wider range of left ventricular ejection fraction (LVEF).
- To advocate for the inclusion of hypertensive HFpEF patients in treatment protocols previously limited to reduced ejection fraction.
Main Methods:
- Analysis of current data and clinical trial outcomes in HFpEF.
- Review of HF classification criteria and LVEF normal ranges.
- Examination of HFpEF phenotypes, focusing on hypertensive heart disease.
Main Results:
- Current HFpEF trials predominantly included patients with hypertension and excluded valvular heart disease and hypertrophic cardiomyopathy.
- Neurohormonal and SGLT2 inhibitors demonstrated efficacy in HF patients across a broad spectrum of LVEF.
- The efficacy of these treatments was observed even in HFpEF patients with higher LVEF values.
Conclusions:
- Restricting life-saving treatments like neurohormonal and SGLT2 inhibitors to only HF patients with reduced LVEF is no longer justified.
- Hypertensive HFpEF represents a significant and common phenotype that warrants consideration for these advanced therapies.
- Treatment guidelines should be updated to include HFpEF patients, especially those with hypertension, for neurohormonal and SGLT2 inhibitor therapies.
Abstract:
Current data indicate that in the community, approximately 50% of patients with heart failure (HF) have preserved left ventricular (LV) ejection fraction (LVEF)—the so-called HFpEF. Treatment of HFpEF has been considered an unmet need for decades. We believe that the main underlying reasons have been (a) the ever-changing LVEF cut-offs used for HF classification; (b) controversies regarding the definition of the LVEF normal range; (c) the fact that HFpEF does not represent a phenotype, but a category of diseases with entirely different characteristics (hypertensive heart disease, valvular heart disease (VHD), hypertrophic cardiomyopathy (HCM) etc.); (d) the lack of recognition that hypertensive HFpEF is the most common and important HFpEF phenotype; (e) the assumption that neurohormonal overactivity is absent in HF patients with a LVEF > 45−50% which has been proven to be wrong. Current HFpEF trials, in which the vast majority of the participants suffered from hypertension (HTN), whereas VHD and HCM were absent, demonstrated that neurohormonal and sodium-glucose cotransporter 2 (SGLT2) inhibitors are effective in HF patients over a wide LVEF range. Thus, restricting these lifesaving treatments to HF patients with reduced LVEF is not justified anymore and it should be additionally considered for HFpEF patients suffering from HTN.
