Résumé
Whether ultrathin-strut stents are particularly beneficial for lesions requiring implantation of more than 1 stent is unknown. In a post-hoc lesion-level analysis of 2 randomized trials comparing ultrathin-strut biodegradable polymer Sirolimus-eluting stents (BP-SES) vs thin-strut durable polymer Everolimus-eluting stents (DP-EES), lesions were stratified into multistent lesions (MSL) vs single-stent lesions (SSL). The primary endpoint was target lesion failure (TLF), a composite of lesion-related unclear/cardiac death, myocardial infarction (MI), or revascularization, at 24 months. Among 5328 lesions in 3397 patients, 1492 (28%) were MSL (722 with BP-SES, 770 with DP-EES). At 2 years, TLF occurred in 63 lesions (8.9%) treated with BP-SES and 60 lesions (7.9%) treated with DP-EES in the MSL-group (subdistibution hazard ratio [SHR], 1.13; 95% CI, 0.77-1.64; P = .53), and in 121 (6.4%) and 136 (7.4%) lesions treated with BP-SES and DP-EES respectively (SHR, 0.86; 95% CI, 0.62-1.18; P = .35) in the SSL-group (P for interaction = .241). While the rates of lesion-related MI or revascularization were significantly lower in SSL treated with BP-SES as compared to DP-EES (3.5% vs 5.2%; SHR, 0.67; 95% CI 0.46-0.97; P = .036), no significant difference was observed in MSL (7.1% vs 5.4%; SHR, 1.31; 95% CI 0.85-2.03; P = .216) with significant interaction between groups (P for interaction = .014). Rates of TLF are similar between ultrathin-strut BP-SES and thin-strut DP-EES in MSL and SSL. The use of ultrathin-strut BP-SES vs thin-strut DP-EES did not prove to be particularly beneficial for the treatment of multistent lesions. Post-hoc analysis from the BIOSCIENCE (NCT01443104) and BIOSTEMI (NCT02579031) trials.

BACKGROUND
Whether ultrathin-strut stents are particularly beneficial for lesions requiring implantation of more than 1 stent is unknown.
METHODS
In a post-hoc lesion-level analysis of 2 randomized trials comparing ultrathin-strut biodegradable polymer Sirolimus-eluting stents (BP-SES) vs thin-strut durable polymer Everolimus-eluting stents (DP-EES), lesions were stratified into multistent lesions (MSL) vs single-stent lesions (SSL). The primary endpoint was target lesion failure (TLF), a composite of lesion-related unclear/cardiac death, myocardial infarction (MI), or revascularization, at 24 months.
RESULTS
Among 5328 lesions in 3397 patients, 1492 (28%) were MSL (722 with BP-SES, 770 with DP-EES). At 2 years, TLF occurred in 63 lesions (8.9%) treated with BP-SES and 60 lesions (7.9%) treated with DP-EES in the MSL-group (subdistibution hazard ratio [SHR], 1.13; 95% CI, 0.77-1.64; P = .53), and in 121 (6.4%) and 136 (7.4%) lesions treated with BP-SES and DP-EES respectively (SHR, 0.86; 95% CI, 0.62-1.18; P = .35) in the SSL-group (P for interaction = .241). While the rates of lesion-related MI or revascularization were significantly lower in SSL treated with BP-SES as compared to DP-EES (3.5% vs 5.2%; SHR, 0.67; 95% CI 0.46-0.97; P = .036), no significant difference was observed in MSL (7.1% vs 5.4%; SHR, 1.31; 95% CI 0.85-2.03; P = .216) with significant interaction between groups (P for interaction = .014).
CONCLUSIONS
Rates of TLF are similar between ultrathin-strut BP-SES and thin-strut DP-EES in MSL and SSL. The use of ultrathin-strut BP-SES vs thin-strut DP-EES did not prove to be particularly beneficial for the treatment of multistent lesions.
