JACC Cardiovasc ImagingPublished

  • Post hoc analysis of the CENTURY randomised trial
  • sex comparison

Authors' conclusion

In the randomized CENTURY trial, women had higher CBF than men across all comparable strata.

Study context

Population
Participants of the CENTURY trial with stable coronary artery disease (CAD), assessed by PET quantitative coronary blood flow
Participants
331 vs 697
Comparison
Women vs men
  • Womenn = 331
  • Menn = 697reference

Primary result

As reported in the abstract

Rest and stress coronary blood flow (PET)

Rest and stress coronary blood flow (CBF) higher in women than in men across all comparable strata of age, BMI, risk factors and treatment

33%

Clinical outcomes (Kaplan-Meier) · through 14 years of follow-up

Women had approximately half the event rates of men

Baseline characteristics

Similar age, BMI, hypertension, DM and cumulative summed risk scores
Women had less established CAD, lower CAC and fewer PET perfusion defects

Estimated global endothelial shear stress (with published ~10% smaller coronary arteries in women)

Potential global endothelial shear stress higher in women than in men
