Comparison of the Biodegradable Polymer Biolimus-Eluting Stents（BP-BES） and Durable Polymer Everolimus-Eluting Stent (DP-EES) in Patients with Coronary Artery Disease at five years follow up：A Systemic Review and Meta-analysis

Biodegradable polymer biolimus-eluting stents (BP-BES) coated with biodegradable polymer were expected to reduce the risk of late stent thrombosis, very late stent thrombosis, and to improve the outcomes of patient undergone percutaneous coronary intervention (PCI). we undertook to pool the data from clinical trials and observational studies to assess the safety and efficacy of BP-BES versus DP-EES at five-year follow-up in patients refer for PCI.
