Abstract

Poor diet, gut dysbiosis, and systemic inflammation constitute a gut-heart axis (GHA) that may affect heart failure with preserved ejection fraction. Clinical scale models to interrogate this axis are limited. Here, we show the full extent of the GHA–gut barrier function loss, systemic and microvascular inflammation, and its colocalization with apoptosis (left atrium) and hypertrophy (left ventricle). Gut barrier function primacy in regulating the GHA is supported by a synbiotic intervention that shuts down gut epithelial permeability, markedly decreasing systemic inflammation and, remarkably, cardiac structural changes in left heart chambers. These data support a new paradigm for targeting heart failure with preserved ejection fraction via the GHA.

期刊介绍： JACC: Basic to Translational Science is an open access journal that is part of the renowned Journal of the American College of Cardiology (JACC). It focuses on advancing the field of Translational Cardiovascular Medicine and aims to accelerate the translation of new scientific discoveries into therapies that improve outcomes for patients with or at risk for Cardiovascular Disease. The journal covers thematic areas such as pre-clinical research, clinical trials, personalized medicine, novel drugs, devices, and biologics, proteomics, genomics, and metabolomics, as well as early phase clinical trial methodology.
