Background

Despite the progress made during the last decades in the prevention and treatment of cardiovascular diseases, heart failure is still associated with a high risk of hospitalization, especially in elderly patients (>65 years), and 1-year mortality can reach 20-25% with considerable costs for national health systems.

In recent years the prevalence of heart failure with preserved ejection fraction (HFpEF) has been progressively increasing (now approximately 50% of HF), and this is due to several factors, among which the aging of the population and the increase in the incidence of conditions such as arterial hypertension, diabetes and obesity are certainly relevant. While these factors are recognized, there remains a necessity to explore beyond them. In fact, it has been known for many years and with considerable support from scientific literature that insulin resistance with associated hyperinsulinemia determines over the years, if neglected, type 2 diabetes and cardiovascular diseases, including hypertension, atherosclerosis and heart disease with concentric remodeling of the left ventricle, and this to remain only in the cardiovascular field. It is also known that the prevalence of insulin resistance in the general population is progressively increasing in developed and developing countries. Furthermore, the prevalence of insulin resistance is very high in subjects with HF, particularly in those with HFpEF. Insulin resistance is a condition in which certain amounts of insulin result in insufficient control of glucose metabolism compared to that expected, so that the pancreas, in order to maintain glucose levels in the normal range, is forced, as much as it can, to chronically secrete greater amounts of insulin. For this reason, hyperinsulinemia is a constant feature of insulin resistance.

It is very likely that there is a close causal relationship between insulin resistance/hyperinsulinemia and development or worsening of HFpEF.

This Research Topic aims to decode the intricate relationship between insulin resistance, hyperinsulinemia, and HFpEF. We aim to deepen the understanding of the mechanisms connecting insulin resistance to the pathophysiology of HFpEF. Moreover, the research intends to identify therapeutic and preventive strategies to mitigate this interrelation. Our goal encompasses exploring causal pathways and plausible interventions, potentially unveiling novel treatments and preventive approaches for HFpEF.

To gather further insights into these interactions and potential implications, we welcome articles addressing, but not limited to, the following themes:
o Mechanisms linking insulin resistance and HFpEF.
o Epidemiological studies on insulin resistance in heart failure patients.
o Clinical trials focusing on interventions targeting insulin resistance in HFpEF.
o Assessing the role of hyperinsulinemia in the progression of HFpEF.
o Novel therapeutics aimed at reducing insulin resistance in the context of heart failure.

Topic editors

Frequently asked questions

  • Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

    Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

  • The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

    Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

  • As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

    A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

  • Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

  • Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

    As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

    Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

  • Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
