Five-year clinical outcomes of zotarolimus-eluting stents in coronary total occlusions.

ABSTRACT:

Aims

Reports of long-term outcomes of patients treated with drug-eluting stents in total coronary occlusions are limited. We analysed clinical outcomes of patients treated with the zotarolimus-eluting Resolute stent (R-ZES) implanted in coronary total occlusions versus non-occluded lesions.

Methods and results

Patients treated with R-ZES and included in four trials (RESOLUTE All Comers, RESOLUTE International, RESOLUTE China RCT, and RESOLUTE China Registry) were pooled and divided into three groups - patients with chronic total occlusions (CTO), patients with total occlusions that had occurred recently (rec-TO), and patients without total occlusions (non-TO). Clinical outcomes at five years were analysed. Of 5,487 patients treated with R-ZES in these trials, 8.0% had CTOs, 8.5% rec-TOs and 83.5% non-TOs. Patients had a mean age of 62.8 years, approximately 25% were female and 30% were diabetics. TLF was similar in the three groups at five years (TLF was 13.2%, 12.5% and 13.3% in the CTO, rec-TO and non-TO groups, respectively, p=0.96). Stent thrombosis tended to occur more frequently for rec-TO compared to CTO and non-TO patients (2.6% vs 1.2% and 1.3%, respectively, p=0.11).

Conclusions

In this large population of patients who had R-ZES implanted, five-year clinical outcomes were similar whether or not the stents were implanted in total occlusions.

Project description:BackgroundImproved outcomes in patients with diabetes mellitus undergoing percutaneous coronary intervention remain an unmet clinical need. We assessed the long-term efficacy and safety of novel polymer-free sirolimus- and probucol-eluting stent in diabetic patients enrolled in intracoronary stenting and angiographic results: test efficacy of sirolimus- and probucol-eluting versus zotarolimus-eluting stents 5 trial.MethodsIn a pre-specified subgroup analysis, outcomes of diabetic patients treated with a sirolimus- and probucol-eluting stent or a second-generation zotarolimus-eluting stent were compared. The primary endpoint was a device-oriented composite outcome comprising cardiac death, target vessel-related myocardial infarction (MI), or target lesion revascularization (TLR) at 5-year follow-up. Event-free survival was assessed using the Kaplan-Meier method. Hazard ratios (HR) and 95 % confidence intervals (CI) were estimated from univariate Cox proportional hazards models.ResultsA total of 870 patients with diabetes mellitus were treated with either a sirolimus- and probucol-eluting stent (n = 575) or a second-generation zotarolimus-eluting stent (n = 295). At 5 years, the rate of device-oriented composite endpoint was comparable between the sirolimus- and probucol-eluting stent and the second-generation zotarolimus-eluting stent (32.9 versus 33.4 %, HR 0.88, 95 % CI 0.76-1.26). No significant differences were observed between the sirolimus- and probucol-eluting stent and the second-generation zotarolimus-eluting stent groups in the incidence of cardiac death (15.6 versus 16.7 % HR 0.92, 95 % CI 0.63-1.32), target-vessel MI (4.6 versus 6.6 %, HR 0.73, 95 % CI 0.40-1.34), and TLR (18.6 versus 18.8 %, HR 1.00, 95 % CI, 0.72-1.41). The rate of definite or probable stent thrombosis was low and similar in both groups (2.5 versus 2.6 %, HR 1.02, 95 % CI, 0.41-2.52).ConclusionsIn patients with diabetes the long-term efficacy and safety of a polymer-free sirolimus- and probucol-eluting stent were comparable to a second-generation durable polymer zotarolimus-eluting stent.

Project description:Background The choice of optimal drug-eluting stent therapy for patients with diabetes mellitus (DM) undergoing percutaneous coronary intervention remains uncertain. We aimed to assess the long-term clinical outcomes after percutaneous coronary intervention with biodegradable polymer sirolimus-eluting stents (BP-SES) versus durable polymer everolimus-eluting stents (DP-EES) in patients with DM. Methods and Results In a prespecified subgroup analysis of the BIOSCIENCE (Ultrathin Strut Biodegradable Polymer Sirolimus-Eluting Stent Versus Durable Polymer Everolimus-Eluting Stent for Percutaneous Coronary Revascularization) trial (NCT01443104), patients randomly assigned to ultrathin-strut BP-SES or thin-strut DP-EES were stratified according to diabetic status. The primary end point was target lesion failure, a composite of cardiac death, target vessel myocardial infarction, and clinically indicated target lesion revascularization, at 5 years. Among 2119 patients, 486 (22.9%) presented with DM. Compared with individuals without DM, patients with DM were older and had a greater baseline cardiac risk profile. In patients with DM, target lesion failure at 5 years occurred in 74 patients (cumulative incidence, 31.0%) treated with BP-SES and 57 patients (25.8%) treated with DP-EES (risk ratio, 1.23; 95% CI, 0.87-1.73 [P=0.24]). In individuals without DM, target lesion failure at 5 years occurred in 124 patients (16.8%) treated with BP-SES and 132 patients (16.8%) treated with DP-EES (risk ratio, 0.98; 95% CI, 0.77-1.26 [P=0.90; P for interaction=0.31]). Cumulative 5-year incidence rates of cardiac death, target vessel myocardial infarction, clinically indicated target lesion revascularization, and definite stent thrombosis were similar among patients with DM treated with BP-SES or DP-EES. There was no interaction between diabetic status and treatment effect of BP-SES versus DP-EES. Conclusions In a prespecified subgroup analysis of the BIOSCIENCE trial, we found no difference in clinical outcomes throughout 5 years between patients with DM treated with ultrathin-strut BP-SES or thin-strut DP-EES.
