Oscillatory ventilation during exercise in patients with chronic heart failure: clinical correlates and prognostic implications.
STUDY OBJECTIVES Although breathing disorders are often found in patients with chronic heart failure, exertional oscillatory ventilation (EOV) has been occasionally described. The aim of this study was to determine the prevalence, clinical characteristics, and outcome of patients with chronic heart failure and EOV. SETTING Cardiology division at tertiary-care hospital. STUDY POPULATION We s...
متن کاملExercise oscillatory ventilation in patients with Fontan physiology.
BACKGROUND Exercise oscillatory ventilation (EOV) refers to regular oscillations in minute ventilation (VE) during exercise. Its presence correlates with heart failure severity and worse prognosis in adults with acquired heart failure. We evaluated the prevalence and predictive value of EOV in patients with single ventricle Fontan physiology. METHODS AND RESULTS We performed a cross-sectional...
متن کاملExercise training reverses exertional oscillatory ventilation in heart failure patients.
Exertional oscillatory ventilation (EOV) is an ominous prognostic sign in chronic heart failure (CHF), but little is known about the success of specific therapeutic interventions. Our aim was to study the impact of an exercise training on exercise capacity and cardiopulmonary adaptation in stable CHF patients with left ventricular systolic dysfunction and EOV. 96 stable CHF patients with EOV we...
متن کاملExercise ventilation inefficiency in heart failure: pathophysiological and clinical significance.
Heart failure (HF) is a complex syndrome characterized by myocardial dysfunction and a poor prognosis. Among multiple markers of severity, an exercise ventilation inefficiency has important clinical and prognostic value. The pathophysiology determining exercise ventilatory inefficiency is complex and not definitively clarified. Three different mechanisms have been identified: (i) increased dead...
متن کاملExercise oscillatory ventilation in systolic heart failure: an indicator of impaired hemodynamic response to exercise.
BACKGROUND Exercise oscillatory ventilation (EOV) is a noninvasive parameter that potently predicts outcomes in systolic heart failure (HF). However, mechanistic insights into EOV have been limited by the absence of studies relating EOV to invasive hemodynamic measurements and blood gases performed during exercise. METHODS AND RESULTS Fifty-six patients with systolic HF (mean±SEM age, 59±2 ye...
