The Gut Microbiome of Heart Failure With Preserved Ejection Fraction.

ABSTRACT: Background Risk factors for heart failure with preserved ejection fraction (HFpEF) include hypertension, age, sex, and obesity. Emerging evidence suggests that the gut microbiota independently contributes to each one of these risk factors, potentially mediated via gut microbial-derived metabolites such as short-chain fatty acids. In this study, we determined whether the gut microbiota were associated with HFpEF and its risk factors. Methods and Results We recruited 26 patients with HFpEF and 67 control participants from 2 independent communities. Patients with HFpEF were diagnosed by exercise right heart catheterization. We assessed the gut microbiome by bacterial 16S rRNA sequencing and food intake by the food frequency questionnaire. There was a significant difference in α-diversity (eg,
