Outcomes of intravascular ultrasound-guided percutaneous coronary intervention with drug-eluting stents versus bare metal stents for acute coronary syndrome in octogenarians.

The number of percutaneous coronary interventions (PCI) performed for octogenarians with acute coronary syndrome (ACS) continue to increase. The short- and long-term outcomes of intravascular ultrasound (IVUS)-guided PCI with drug-eluting stents (DES) or bare metal stents (BMS) for ACS in octogenarians, however, remain largely unknown. We analyzed clinical outcomes of octogenarians undergoing IVUS-guided PCI for ACS with either DES or BMS. During the study period, a total of 776 patients with ACS underwent IVUS-guided PCI and 75 of them were octogenarians. In-hospital mortality tended to be lower in the DES group than in the BMS group. Between 6 months and 1 year of follow up, treatment with DES compared with BMS tended to result in fewer target lesion revascularizations. Major adverse cardiac events were similar between patients receiving DES and BMS. In octogenarians with ACS treated with IVUS-guided PCI, DES appears as safe as BMS, providing similar short- and long-term outcomes.
