Abstract

INTRODUCTION: Previous studies have examined the associations between physical activity (PA), sedentary time (ST), and sleep on the risk of heart failure (HF). The primary aim of this study was to examine PA, ST, and sleep quality (SQ) in those diagnosed with preserved ejection fraction HF (HFpEF) and reduced ejection fraction HF (HFrEF). The secondary aim of this study was to examine these relationships in those with and without HF, independent of sub-type.

METHODS: The Multi-Ethnic Study of Atherosclerosis (MESA) collected data from 6,814 adults from a diversified cohort who range in age from 45 to 84. Subjects were classified with the following HF subtypes: HFpEF (ejection fraction ≥ 50%) or HFrEF (ejection fraction ≤ 40%). A total of 178 participants reported or were diagnosed with HF (HFpEF=74, HFrEF=69). Continuous PA and ST variables were created from self-reported minutes per week and SQ was reported via questionnaire.

RESULTS: No significant differences were found when examining the associations of ST and SQ between HF sub-types. However, an association of PA between subtypes was found to be significant. Those with HFrEF reported 401 (P

CONCLUSIONS: Our findings suggest that PA significantly differs between HF subtypes. When examining those with and without HF, those with HF reported significantly less TPAV, light-, moderate-, and vigorous-intensity PA, and significantly more ST. Future studies with greater power and objectively measured PA, ST, and SQ data may improve both internal and external validity of HF research.
