  • validation in the Western Denmark Heart Registry

Authors' conclusion

In 2 population-based cohorts undergoing first-time ICA for suspected NSTE-ACS, 40 to 50% of women had no significant CAD, approximately twice the proportion to men, highlighting ongoing challenges in risk stratification of patients referred for ICA.

Study context

Population
Adults without previously known coronary artery disease (CAD) undergoing first-time invasive coronary angiography (ICA) for suspected non-ST-elevation acute coronary syndrome (NSTE-ACS)patients included from Sweden and Western Denmark · Sweden (Swedish Coronary Angiography and Angioplasty Registry) 74,883 · Western Denmark (Western Denmark Heart Registry) 17,863
Exposure
Women compared to men
Outcome
Absence of significant CAD (normal angiography or <50% stenosis in all major epicardial vessels)

Main finding

As reported in the abstract

Women vs menAdjusted relative risk (95% CI)
Swedish Coronary Angiography and Angioplasty Registry: 40.9% vs 17.2%
2.59(2.51–2.67)
Western Denmark Heart Registry: 50.1% vs 25.2%
2.01(1.95–2.08)

Observational data: associations, not effects.

Secondary outcomes

No significant CAD in women below the age of 50 without any traditional cardiovascular risk factors (subgroup)

Women below the age of 50 without any traditional cardiovascular risk factors with no significant CAD
74.8%
