Effectiveness of Exercise on Fatigue for Patients With Heart Failure: A Systematic Review and Meta-Analysis

Abstract

Exercise is the standard treatment for fatigue in heart failure (HF) patients. However, no study has investigated the effect of exercise on improving fatigue and HR-QoL in HF patients. Our study adhered to the Cochrane Handbook for Systematic Reviews of Interventions and followed the PRISMA statement. The date of the last search was October 31, 2021. We included randomized controlled trials (RCTs) using exercise to improve fatigue and HR-QoL. The combined exercise training studies showed improvement in fatigue (SMD = −.51, 95% CI = −.89 to −.12, p = .001, I2 = 48%). The IMT studies showed significantly improved fatigue (MD = −11.36, 95%CI = −15.30 to −7.41, p < .00001, I2 = 54%). However, three studies, with moderate heterogeneity ( p = .10, I2 = 56%), showed non-significant changes in HR-QoL (SMD = −0.04, 95% CI = −.45 to .37, p = .83).
