Abstract

Aims: Sedentary behavior (SB) has emerged as an important risk factor for poor health. Evidence showed that patients with heart failure (HF) exhibit high levels of SB, and that high SB increases mortality among such patients. We aimed to identify factors associated with SB in HF patients. Methods: A cross-sectional study was carried out with adults with HF and categorized under New York Heart Association (NYHA) functional class I-III. Sociodemographic, clinical, and health information were gathered. Evaluation of SB (by sitting time) and moderate-to-vigorous physical activity (MVPA) was performed by self-reported measures. Functional capacity was assessed using the Duke Activity Status Index. Simple and multivariate linear regression analyses were performed to identify the most suitable predictive model. Results: The sample (n = 80) comprised predominantly of patients in functional class I, men, and with an average age of 50.8 years. Time spent on SB totaled to 7.69 ± 2.35 h/day. Weekly volume of MVPA, functional capacity, and previous stroke were predictors of higher SB. Using simple linear regression analysis, the variables body mass index, quality of life, NYHA functional class, total comorbidities, dyslipidemia, MVPA in the leisure domain, and the use of diuretics, statins, and sildenafil were shown to have a statistically significant association with SB. Conclusion: In patients with HF, a longer time spent in SB was associated with low volumes of MVPA, low functional capacity, and history of stroke. More studies are needed to corroborate these findings.

Highlights

Heart failure (HF) is a debilitating, progressive, and highmortality clinical syndrome 1
Doukky et al.[19] observed that with increasing sedentary time, risk of all-cause mortality and cardiac causes gradually increases in patients with HF. These patients generally do not meet the recommendations of moderate-to-vigorous physical activity (MVPA) 3, 4, 18, 20 of at least 30 min/day; this insufficient activity may be an aggravating factor given that sedentary behavior (SB) is especially detrimental in individuals who perform low physical activity levels 21, 22
A common phenotype is observed in HF patients: high SB along with low physical activity

Summary

Introduction

Heart failure (HF) is a debilitating, progressive, and highmortality clinical syndrome 1. Doukky et al.[19] observed that with increasing sedentary time, risk of all-cause mortality and cardiac causes gradually increases in patients with HF. These patients generally do not meet the recommendations of moderate-to-vigorous physical activity (MVPA) 3, 4, 18, 20 of at least 30 min/day; this insufficient activity may be an aggravating factor given that SB is especially detrimental in individuals who perform low physical activity levels 21, 22. A common phenotype is observed in HF patients: high SB (i.e., sitting time) along with low physical activity (i.e., no MVPA)
