Diet, Vascular Health and the Gut Microbiome in Heart Failure

Overview

About this study

Heart failure with reduced ejection (HFrEF) is a major health concern. HFrEF is associated with significant endothelial dysfunction (ED). The purpose of this study is to compare the effects of a Western diet (WD) to a high-carbohydrate, high-fiber diet (HCHF) on endothelial function in patients with HFrEF. the study will look at the distribution of intestinal microbe communities after following the diets as well as explore relationships between gut health and ED in patients with HFrEF.

We propose to address this important gap in the literature with a study design that is responsive to needs in the area of healthcare delivery and disease management in this population of patients.
