Preserved right ventricular ejection fraction predicts exercise capacity and survival in advanced heart failure.
OBJECTIVES This study was undertaken to determine which exercise and radionuclide ventriculographic variables predict prognosis in advanced heart failure. BACKGROUND Although cardiopulmonary exercise testing is frequently used to predict prognosis in patients with advanced heart failure, little is known about the prognostic significance of ventriculographic variables. METHODS The results of...
متن کاملRight ventricular function in patients with preserved and reduced ejection fraction heart failure.
AIMS To determine the prevalence of right ventricular (RV) dysfunction in patients with preserved left ventricular (LV) ejection fraction (EF) heart failure (HF) and to compare RV function between patients with preserved EF HF and those with reduced EF HF. METHODS AND RESULTS Hundred patients (72 +/- 14 years, 59% male) with HF were prospectively enrolled. Fifty-one had preserved EF HF (LVEF ...
متن کاملEffect of inorganic nitrate on exercise capacity in heart failure with preserved ejection fraction.
BACKGROUND Inorganic nitrate (NO3(-)), abundant in certain vegetables, is converted to nitrite by bacteria in the oral cavity. Nitrite can be converted to nitric oxide in the setting of hypoxia. We tested the hypothesis that NO3(-) supplementation improves exercise capacity in heart failure with preserved ejection fraction via specific adaptations to exercise. METHODS AND RESULTS Seventeen su...
متن کاملResting ventricular-vascular function and exercise capacity in heart failure with preserved ejection fraction: a RELAX trial ancillary study.
BACKGROUND Exercise intolerance is a hallmark of heart failure, but factors associated with impaired exercise capacity in heart failure with preserved ejection fraction are unclear. We hypothesized that in heart failure with preserved ejection fraction, the severity of resting ventricular and vascular dysfunction are associated with impairment in exercise tolerance as assessed by peak oxygen co...
