Does oxygen uptake at aerobic threshold (VO2 at AT) predict cardiovascular and all-cause mortality in men from the general population?
Does oxygen uptake at aerobic threshold (VO2 at AT) predict cardiovascular and all-cause mortality in men from the general population?
Oxygen uptake at aerobic threshold (VO2 at AT) is a useful prognostic marker for cardiovascular and all-cause mortality, particularly valuable for patients unable to achieve maximal VO2 during exercise testing.
VO2 at AT may aid mortality stratification when peak VO2 is unattainable; leaves open its independent value beyond peak VO2.
VO₂ at AT is inversely associated with cardiovascular and all-cause mortality events, but the associations are partly dependent on peak VO₂. VO₂ at AT may improve the prediction of the long-term risk for CVD mortality. KEY MESSAGES Oxygen uptake at aerobic threshold (VO₂ at AT), a cardiopulmonary exercise testing parameter, may be a useful prognostic tool for adverse clinical outcomes in the general population. In a population-based prospective cohort study of men, VO₂ at AT was inversely associated with cardiovascular and all-cause mortality events and improved the prediction of cardiovascular mortality. In populations who cannot achieve maximal VO₂, VO₂ at AT may serve as a useful prognostic tool; however, further studies are warranted.
