Safety and Efficacy of Aerobic Exercise Training Associated to Non-Invasive Ventilation in Patients with Acute Heart Failure.

Background: Exercise training (ET) improves functional capacity in chronic heart failure (HF). However, ET effects in acute HF are unknown.

Objective: To investigate the effects of ET alone or combined with noninvasive ventilation (NIV) compared with standard medical treatment during hospitalization in acute HF patients.
