Authors' conclusion

In patients with newly diagnosed HFrEF, the presence and extent of CAD has significantly greater prognostic impact among women than among men.

Study context

Population
Patients with newly diagnosed heart failure and reduced ejection fraction (HFrEF) referred for first-time coronary angiography891 women and 2,403 men
Exposure
Coronary artery disease (CAD) vs no CAD, women vs men
Outcome
All-cause mortality
Follow-up
10 years

Main finding

As reported in the abstract

10-year all-cause mortality
adjusted for comorbidities
Adjusted hazard ratio (95% CI)
Women without CAD vs Men without CAD
0.73(0.58–0.91)
Women with CAD vs Men with CAD
1.00(0.81–1.24)

Observational data: associations, not effects.
