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 ye...
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...
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 کاملTreating exercise oscillatory ventilation in heart failure: the detail that may matter.
O ver the last 15 yrs, cardiologists have had to face a progressive recognition that abnormalities in the ventilatory response to exercise are relevant features of the heart failure syndrome [1]. Prior pathophysiology studies have defined the mechanistic role of the lung (impaired perfusion and increased minute ventilation (V9E)) [2] and of the periphery (increased chemo/metaboreflex sensitivit...
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...
