Abstract
Patients with heart failure with preserved ejection fraction (HFpEF) are burdened by multiple diet-sensitive comorbidities, including obesity and malnutrition. Despite this, a low percentage of patients with HFpEF have been enrolled in dietary intervention trials in heart failure and few dietary interventions have been conducted in HFpEF exclusively. This scoping review will examine available evidence regarding dietary interventions in patients with HFpEF, highlight existing gaps in knowledge, and discuss emerging dietary therapies in this population.
