Exercise training effects on metabolic and ventilatory changes in heart failure patients with exercise oscillatory ventilation: systematic review and meta-analysis

Exercise oscillatory ventilation (EOV) is a phenomenon characterized by cyclic oscillations in the ventilatory pattern observed during the cardiopulmonary exercise test (EOV characteristics: Supplementary material online, Figure 1S). It is considered an independent predictor for death and adverse cardiovascular events in chronic heart failure (CHF) patients.1 A recent meta-analysis showed that EOV-positive patients exhibited a worse peak oxygen...
