- BACKGROUND: No previous studies have evaluated the performance of the Synergy stent in a large real-life population.OBJECTIVES: To describe the initial real-life experience with a novel everolimus eluting platinum chromium stent with abluminal biodegradable polymer (SYNERGY) in unselected patients from a nationwide registry.METHODS: All implanted Synergy stents were compared with other new generation drug eluting stents (n-DES) with >1,000 implantations in Sweden between March 2013 and October 2015. Restenosis, definite stent thrombosis (ST), myocardial infarction (MI) and death rates were assessed using propensity score and Cox regression analyses.RESULTS: A total of 7,886 of Synergy stents and 64,429 other n-DES (BioMatrix, N = 1,953; Orsiro, N = 4,946; Promus Element Plus, N= 2,543; Promus Premier, N= 20,414; Xience Xpedition, N= 7,971, Resolute/Resolute Integrity, N = 19,021; Ultimaster, N = 1,156; Resolute Onyx, N = 6,425) were implanted in 42,357 procedures. Restenosis and stent thrombosis occurred in 642 and 314 cases, respectively, in the overall population at 1 year. The cumulative rate of restenosis (1.1% vs. 1.0%, adjusted HR: 1.24 95% CI: 0.88-1.75; P = 0.21) and ST (0.4% vs. 0.5%, adjusted HR: 0.97; 95% CI: 0.63-1.50; P = 0.17) up to 1 year was low in both the Synergy group and the other n-DES group. Death occurred in 5.2% versus 4.5% (adjusted HR: 1.14; 95% CI: 0.96-1.36; P = 0.11) and MI in 3.2% versus 3.5%, (adjusted HR: 1.11; 95% CI: 0.93-1.33; P = 0.24) up to 1 year.CONCLUSIONS: In a large real-life population the Synergy stent appears to be safe and effective with a low rate of restenosis and ST comparable with other n-DES.
