Abstract 10199: Atrial Fibrillation is Associated With Impaired Exercise Capacity and Adverse Prognosis in Heart Failure Patients With Mid-range Ejection Fraction

IntroductionExercise capacity represented by peak oxygen uptake (VO2) is an independent predictor of cardiac event in heart failure (HF) patients with reduced ejection fraction. However, factors associated with impaired peak VO2 has not been fully examined in HF patients with mid-range ejection frac...

Zusammenfassung:IntroductionExercise capacity represented by peak oxygen uptake (VO2) is an independent predictor of cardiac event in heart failure (HF) patients with reduced ejection fraction. However, factors associated with impaired peak VO2 has not been fully examined in HF patients with mid-range ejection fraction (HFmrEF).Methods and ResultsWe divided hospitalized 128 HFmrEF patients based on peak VO2the control group (peak VO2 ≥14 mL/kg/min, n = 83, 64.8%) and the impaired group (peak VO2
