Abstract

The RESOLUTE China Registry is a prospective, multicenter, all-comers, observational study of patients in China implanted with the Resolute zotarolimus-eluting stent (R-ZES). R-ZES was commercially available before the enrollment began. All patients suitable for R-ZES implantation according to applicable guidelines were candidates for enrollment at 30 centers and were treated per standard hospital practice. Dual antiplatelet therapy (DAPT) was prescribed for a minimum of 6 months per current European Society of Cardiology guidelines and the device instructions for use. There were 1,800 patients enrolled with a mean age of 61.3 ± 10.9 years, 76% of patients were men, and 61% had complex disease. DAPT use was 94% at 1 year. Target lesion failure (cardiac death, target vessel myocardial infarction, or clinically driven target lesion revascularization) at 1 year was 3.5% (95% confidence interval 2.7% to 4.5%). The rate of cardiac death was 0.6%, target vessel myocardial infarction 2.3%, and clinically driven target lesion revascularization 0.9%. The 1-year rate of definite or probable stent thrombosis was 0.5% (8 of 1,750); 0.4% (7 of 1,750) occurred early (0 to 30 days) and 1 event occurred late (1 to 12 months). One stent thrombosis occurred in a patient who had an interruption of DAPT within the first month; all other stent thromboses occurred while on DAPT. Outcomes did not differ significantly between monitored and unmonitored patients (difference in target lesion failure, p = 0.264). In conclusion, the RESOLUTE China Registry confirms the safety and effectiveness of R-ZES in a large real-world Chinese population.
