Differences in coronary artery disease and outcomes of percutaneous coronary intervention with drug-eluting stents in women and men.

Despite common perceptions, coronary artery disease (CAD) is not a male-specific condition, and sex-based differences do occur in many aspects, including clinical outcomes after percutaneous coronary intervention (PCI) with stent implantation. New-generation drug-eluting stents (DES) significantly improved post-PCI outcomes. However, no sex-specific guidelines on PCI and the use of DES are available as current evidence was derived from clinical trials enrolling predominantly male patients. This review aims at exploring sex-based disparities in CAD characteristics and manifestations, and comparing PCI outcomes and the efficacy and safety profiles of DES according to sex. In addition, a critical approach to trials' interpretation with an analysis of sources of bias is provided to inform future research and clinical practice. Sex gap in clinical outcomes after PCI with DES implantation is narrowing due to improved performances of new-generation DES. However, scientific research and biomedical engineering are striving to optimize DES profiles and generate new iterations of devices. At the same time, gender initiatives and sex-specific trials are accruing to overcome current issues in the field. Advances in these areas will foster improvements in early and long-term clinical outcomes of both women and men.
