Sex Differences in Outcomes After Cardiac Catheterization: Effect Modification by Treatment Strategy and Time
CONTEXT Studies comparing outcomes of cardiac care in women vs men yield various results, with some suggesting worse outcomes for women and others suggesting equivalent outcomes. OBJECTIVE To determine whether extent of coronary disease, treatment strategy, and follow-up time influence the risk of d...

Zusammenfassung: | CONTEXT Studies comparing outcomes of cardiac care in women vs men yield various
results, with some suggesting worse outcomes for women and others suggesting
equivalent outcomes. OBJECTIVE To determine whether extent of coronary disease, treatment strategy,
and follow-up time influence the risk of death in women vs men among patients
who have had cardiac catheterization. DESIGN, SETTING, AND PATIENTS We studied a large inception cohort by using detailed clinical data
from a registry of 37 401 patients undergoing cardiac catheterization
in Alberta, Canada, from 1995-2000, with follow-up through December 31, 2001. MAIN OUTCOME MEASURES The risk of death for women vs men was assessed for all patients combined
and then in analyses stratified by degree of coronary anatomic risk and by
treatment strategy (no revascularization, percutaneous coronary intervention
[PCI], coronary artery bypass graft [CABG] surgery). The latter analysis included
a graphic assessment of the changing relative risk over time for women vs
men. RESULTS Women had higher 1-year mortality than men did (5.6% vs 4.6%; P |
