Efficacy and safety of functional electrical stimulation of lower limb muscles in elderly patients with chronic heart failure: A pilot study
2015
BackgroundExercise training is an established modality in chronic heart failure. Functional electrical stimulation (FES) is an effective alternative mode of training in patients unwilling or unable to exercise; however, it has not been investigated in elderly patients. We sought to investigate the effects of FES on functional status, quality of life, emotional status and endothelial function in chronic heart failure patients aged 70 years or higher.MethodsThirty patients with stable systolic chronic heart failure (mean age 75 ± 3 years, New York Heart Association (NYHA) class II/III, 37%/63%) randomly underwent a six-week FES training programme or placebo. Questionnaires addressing quality of life (Kansas City Cardiomyopathy Questionnaire (KCCQ), functional and overall) and emotional stress (Zung self-rating depression scale (SDS), Beck Depression Inventory (BDI)), as well as endothelial function (flow-mediated dilatation) were assessed at baseline and upon protocol completion.ResultsA significant improve...
