Objectives To evaluate the sex difference of percutaneous coronary intervention (PCI) on octogenarian patients with acute coronary syndrome (ACS)

Methods A total of 80 patients aged 80 years and over with ACS undergoing PCI were enrolled in this study. The in-hospital and one year clinical follow-up outcome including all-cause mortality, major adverse cardiac event (MACE), stroke and other major bleeding were collected and analysed.

Results Of the 80 patients, 37 (46.3%) were female and were more likely to have hypertension, single vessel lesion and DES implant while were less likely to have hyperlipidemia and a history of MI, PCI and three vessel lesion. Female patients had a higher in-hospital MACE rate (10.8% vs 7.0%; p > 0.05). Also, at one year, female patients had a similar MACE rate (5.7% vs 4.9%; p = 0.10).

Conclusions Female octogenarian patients with acute coronary syndrome underwent PCI may be associated with increased in-hospital MACE rate. Incomplete revascularisat
