- 2018-049 Oxygen uptake at aerobic threshold is inversely associated with fatal cardiovascular and all-cause mortality events. Kunutsor SK, Kurl S, Khan H, Zaccardi F, Rauramaa R, Laukkanen JA.
Produktbereich: Veröffentlichung: Sprache: Verlag/Herausgeber: Ann Med. 2017 Dec;49(8):698-709. doi: 10.1080/07853890.2017.1367958. Epub 2017 Aug 22
PURPOSE: We aimed to assess the associations of oxygen uptake at aerobic
threshold (VO2 at AT) with cardiovascular and all-cause mortality.
DESIGN: VO2 at AT was assessed in 1663 middle-aged men in a cohort study. Hazard
ratios (HRs) were calculated for sudden cardiac death (SCD), fatal coronary heart
disease (CHD) and cardiovascular disease (CVD) and all-cause mortality.
RESULTS: During a median follow-up of 25.6 years, 138 SCDs, 209 fatal CHDs, 333
fatal CVDs and 719 all-cause mortality events occurred. On adjustment for
established risk factors, the HRs (95% CIs) for SCD, fatal CHD, fatal CVD and
all-cause mortality were 0.48 (0.28-0.82), 0.48 (0.31-0.74), 0.57 (0.41-0.79) and
0.66 (0.53-0.82), respectively comparing extreme quartiles of VO2 at AT. On
further adjustment for peak VO2, the HRs were 0.87 (0.48-1.56), 0.83 (0.52-1.34),
0.91 (0.63-1.30) and 0.88 (0.69-1.12), respectively. Addition of VO2 at AT to a
standard CVD mortality risk prediction model was associated with a C-index change
of 0.0085 (95% CI: -0.0002-0.0172; p = .05) at 25 years.
CONCLUSIONS: 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.
