Exercise 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 oscillatory ventilation may predict sudden cardiac death in heart failure patients.
OBJECTIVES The purpose of this study was to test the ability of cardiopulmonary exercise testing (CPET)-derived variables as sudden cardiac death (SCD) predictors. BACKGROUND The CPET variables, such as peak oxygen uptake (VO2), ventilatory requirement to carbon dioxide (CO2) production (VE/VCO2) slope, and exercise oscillatory breathing (EOB), are strong predictors of overall mortality in ch...
متن کاملOscillatory 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 کاملHeart Failure Exercise 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 year...
