The evolving field of nonpharmacological therapies to improve functional capacity in chronic heart failure

Abstract

Clinical investigations in chronic heart failure (HF) have been increasingly including endpoints related to functional and exercise capacity. Noninvasive ventilation support (NIVS) constitutes a therapeutic option that could improve several markers of cardiovascular performance and functional capacity along with improvements in HF symptoms such as dyspnea. NIVS with bilevel positive airway pressure (BiPAP) is a therapeutic option that can be better tolerated by patients than continuous positive airway pressure (cPAP) and potentially improve the adherence of patients with HF to NIVS. Future investigations should improve our understanding as to how to select patients with HF most amenable to respond favorably, elucidate the frequency and duration of NIVS session required to maintain the observed short-term beneficial effects for a long period of time, and shed additional light on the mechanisms associated with these benefits. In summary, NIVS appears to be a promising nonpharmacological therapy to improve exercise capacity and quality of life in chronic HF.
