Coronary disease & ACSCohort study

Sex-specific V̇O2peak reference values and their association with major adverse cardiovascular events in Norwegian cardiac rehabilitation patients

Eur J Prev CardiolPublished

  • Retrospective cohort study

Authors' conclusion

This study provides novel sex- and diagnosis-specific V̇O2peak reference values for Norwegian CAD patients and confirms V̇O2peak as a strong prognostic marker

Study context

Population
Coronary artery disease (CAD) patients attending inpatient cardiac rehabilitation in Norway (2004–2022), by index event: Myocardial infarction (MI), coronary artery bypass grafting (CABG) or PCI/CAD21% women
Participants
1,651 patients
Exposure
V̇O2peak by sex and diagnosis, and its association with MACE
Outcome
Sex-specific V̇O2peak reference values and association of V̇O2peak with MACE (all-cause mortality, ACS, stroke or HF)

Main finding

As reported in the abstract

V̇O2peak and MACE
MACE per 1 mL·kg-1·min-1 higher V̇O2peak
Hazard ratio (95% CI)
Men
0.93(0.92–0.95)
Women
0.95(0.91–0.99)

Per 1 mL·kg-1·min-1 higher V̇O2peak, as printed

MACE during 7880 person-years
510 patients (36%)
Highest vs lowest cardiorespiratory fitness quartile: lower MACE risk
55%

Observational data: associations, not effects.

Further findings

V̇O2peak by index event

Highest after previous MI, followed by CABG and PCI/CAD
P < 0.001
Associations with MACE consistent across CAD subcategories
