To assess the differences in clinical outcome between complex patients treated with Resolute zotarolimus-eluting stents (ZES) versus Xience V everolimus-eluting stents (EES).


Nowadays, many complex patients with coronary disease are treated with percutaneous coronary interventions, using drug-eluting stents (DES).


We analyzed 2-year outcome data of 1,033 complex patients of the TWENTE trial, treated with second-generation Resolute ZES or Xience V EES. Complex patients had at least one of the following characteristics: renal insufficiency (creatinine ≥ 140 µmol/l); ejection fraction < 30%; acute myocardial infarction (MI) within previous 72 hrs; >1 lesion/vessel; >2 vessels treated; lesion length > 27 mm; bifurcation; saphenous vein graft lesion; arterial bypass graft lesion; in-stent restenosis; unprotected left main lesion; lesion with thrombus; or lesion with total occlusion. Target vessel failure (TVF), the primary composite endpoint of the trial, was defined as cardiac death, target vessel-related MI, or target vessel revascularization.


Among the 1,033 complex patients, 529 (51%) were treated with Resolute ZES and 504 (49%) with Xience V EES. Patient- and procedure-related characteristics were similar between DES groups. After 2-year follow-up, outcome was also similar between DES groups. TVF occurred in 12.1% of patients treated with Resolute ZES and 12.3% of patients treated with Xience V EES. In addition, DES groups did not differ significantly in cardiac death, MI, or target vessel revascularization-the individual components of TVF.


Complex patients treated with Resolute ZES and Xience V EES showed similar safety and efficacy during 2-year follow-up. © 2014 Wiley Periodicals, Inc.
