Figure 2 (A) Total myocardial infarction (MI) (both Q- and nonQ-wave) by stent type (bare-metal stents [BMS], n = 238; sirolimus-eluting stent [SES], n = 337) in patients treated with overlapping stents. (B) Incidence of total MI at 30 days by stent type stratified by total implanted stent length. (C) Total MI at 360 days by stent type stratified by total implanted stent length. Solid bars = BMS; open bars = SES.

Figure 3 Target lesion revascularization (TLR) and target vessel revascularization (TVR) through 360 days as well as target vessel failure (TVF) (composite occurrence of death, myocardial infarction, and TLR) stratified by stent type in patients treated with overlapping stents. BMS = bare metal stent; SES = sirolimus-eluting stent.

Figure 4 In-stent binary (>50%) angiographic restenosis (A) and target lesion revascularization (B) stratified by stent type and overlap (vs. single) stent status. *p < 0.0001 for comparisons sirolimus-eluting stent (SES) versus bare-metal stent (BMS) and BMS overlap versus single stent; p = 0.0016 for SES overlap versus single stent. p < 0.0001 for comparisons SES versus BMS; p = 0.0006 BMS overlap versus single stent; p = NS SES overlap versus single stent. Solid bars = BMS; open bars = SES.
