Introduction: Exercise oscillatory ventilation (EOV) occurs in a subgroup of patients with increased heart failure (HF) severity and poorer prognosis. The purpose of the present investigation is to examine the prognostic value of the timing of the largest ventilatory oscillation in HF patients during exercise testing. Methods: One hundred and forty eight subjects (88 male/60 female, 91 ischemic/57 non-ischemic, mean age: 49.5 ± 12.2 years, mean ejection fraction: 30.0 ± 14.1%) diagnosed with HF underwent cardiopulmonary exercise testing.

Introduction: Exercise oscillatory ventilation (EOV) occurs in a subgroup of patients with increased heart failure (HF) severity and poorer prognosis. The purpose of the present investigation is to examine the prognostic value of the timing of the largest ventilatory oscillation in HF patients during exercise testing. Methods: One hundred and forty eight subjects (88 male/60 female, 91 ischemic/57 non-ischemic, mean age: 49.5 ± 12.2 years, mean ejection fraction: 30.0 ± 14.1%) diagnosed with HF underwent cardiopulmonary exercise testing.Pubblicazioni consigliate
