  1. * Data are number (%), unless otherwise indicated. Plus-minus values are means ± SD.
  2. Type B2 or C lesions according to ACC/AHA classification.
  3. Bifurcation means bifurcated lesion that have been treated solely by drug-eluting stents.
  4. § Small vessel denotes lesion with reference diameter < 2.75 mm.
  5. Long lesion denotes lesion with length ≥ 28 mm.
  6. Abbreviations: EES everolimus-eluting stent, LAD left anterior descending artery, LCX left circumflex artery, RCA right coronary artery, R-ZES Resolute zotarolimus eluting-stent.
