Abstract
There is a paucity of data on long-term outcomes after percutaneous coronary intervention (PCI) for chronic total occlusions (CTOs) in the high-risk group of patients with diabetes mellitus (DM). The aim of this study was to evaluate long-term clinical outcomes after PCI of CTOs in patients with and without DM. A total of 1,742 patients with known DM status underwent PCI of CTOs at 3 tertiary care centers in the United States, South Korea, and Italy from 1998 to 2007. Five-year clinical outcomes were evaluated in patients with successful versus failed CTO PCI and the use of drug-eluting stents (DES) versus bare-metal stents (BMS) stratified according to DM status. A total of 395 patients (23%) had DM (42% of whom had insulin-dependent DM). Procedural success was similar in patients with versus without DM (69.6% vs 67.9%, p = 0.53). After successful CTO PCI, stents were implanted in 96.4% of patients with DM (BMS in 23.8%, DES in 76.2%) and in 94.0% of patients without DM (BMS in 38.6%, DES in 61.4%). Median follow-up was 3.0 years. In patients with DM, successful CTO PCI was associated with reduced long-term mortality (10.4% vs 13.0%, p
