Sex difference in 5-year relative survival following percutaneous coronary intervention

Abstract Background Sex-specific survival following percutaneous coronary intervention (PCI) varies among studies. This might be clarified using relative survival, which adjusts observed in relation to that seen sex- and age-matched general population. We investigated sex-specific after PCI. Methods A total of 48,783 patients were enrolled the year 2011 Korean nationwide PCI cohort. Primary outcome was all-cause death. Observed at 5 years conditional on surviving 0 days, 30 1 year, 2 assessed. differences cardiovascular risk factors adjusted via age-group stratified propensity score matching. Results In unadjusted analyses, 15,710 female had a higher frequency compared with 33,073 male patients. Both (hazard ratio [HR]=1.28, 95% confidence interval [CI]=1.22–1.34) (HR=1.21, CI: 1.16–1.27) worse (p<0.001, all). analyses score-matched 14,454 pairs, showed (HR=0.78, 0.74–0.82) but lower (HR=1.19, 1.13–1.26) Neither nor differed between age≤50s male, they age≥60s than male. These findings consistent further years. Conclusions The 5-year aged≥60 by clinical mandates need for excessive reduction older undergoing Funding Acknowledgement Type funding sources: None.
