Titanium-nitride-oxIde-coated stents multicenter registry in diaBEtic patienTs: the TIBET registry.

摘要

We sought to explore the immediate clinical and angiographic results of the Titan(?) stent implantation in diabetic patients, as well as the major adverse cardiac events (MACE) at 6-month follow-up. We enrolled 156 consecutive diabetic patients admitted to undergo percutaneous intervention for at least one significant (50%) coronary lesion. All lesions were treated with the Titan(?) stent implantation according to the contemporary interventional techniques. Patients were prospectively followed-up for at least 6?months. The primary endpoint was MACE at 6-month follow-up [cardiac death, myocardial infarction (MI), or target lesion revascularization (TLR)]. Secondary endpoints included angiographic and clinical procedural success, in-hospital MACE, TLR at 6-month follow-up, and stent thrombosis. The mean age was 66.7?±?9.6?years, (68.4% males). A total of 197 Titan(?) stents were implanted in 163 lesions. Direct stenting was performed in 45.2% of the cases. The mean stent diameter was 3.1?±?0.61?mm, and the mean length was 18.0?±?8.9?mm. Average stent deployment pressure was 13.9?±?4.2 bars. Angiographic procedural success was achieved in 154 (98.7%) cases, and clinical procedural success was achieved in 153 (98.1%) cases. One patient developed in-hospital non-Q-wave MI following the procedure. Clinical follow-up was completed in 155 (99.4%) patients. Three patients (1.9%) died of a cardiac or unknown cause, and two (1.3%) developed MI. TLR was performed in 11 patients (7.1%). Cumulative MACE at 6-month follow-up occurred in 16 (10.3%) patients. No patient suffered stent thrombosis. Titan(?) stent implantation in diabetic patients achieves an excellent immediate clinical and angiographic outcome, with a low incidence of MACE at mid-term follow-up.
