Low peak oxygen uptake in relation to total heart volume as an early marker of subclinical diastolic dysfunction.
AimPeak oxygen uptake (VO2peak) is closely related to total heart volume (THV) in healthy individuals. This study aimed to investigate 1) the association between VO2peak and THV in subjects with subclinical diastolic dysfunction, athletes, healthy controls, and patients with established heart failure with and without preserved ejection fraction (HFpEF, HFrEF), and 2) whether VO2peak/THV-index can
