Authors' conclusion

Early invasive management in female patients with non-ST-elevation acute coronary syndrome, compared with delayed invasive management, was not associated with a significant reduction in the hazard for the primary end point. In prespecified subgroup analysis, high-risk female patients as assessed with Global Registry of Acute Coronary Events score >140 or elevated cardiac biomarkers experienced significant reductions in all-cause mortality or myocardial infarction at 6 months following early invasive management.
