Clinical outcomes in unselected patients treated with the PROMUS Element platinum-chromium, everolimus-eluting stent: Final five-year results from the PE PROVE Study

Objectives The goal of this analysis was to evaluate the final 5-year safety and effectiveness of the PROMUS Element platinum-chromium everolimus-eluting stent in unselected patients treated in routine clinical practice. Background The prospective, open-label PROMUS Element (TM) European Post-Approval Surveillance Study (PE-PROVE) enrolled 1,010 "real-world" patients who received the PROMUS Element stent. Adverse event rates were low at 1-year, and the incidence of stent thrombosis was 0.6%. Methods The primary endpoint was target vessel failure (TVF; overall and PE stent-related), a composite of cardiac death, myocardial infarction (MI) related to the target vessel, or target vessel revascularization (TVR) at 1-year post-implantation. Five-year clinical outcomes were evaluated in overall as well as high-risk patient subgroups. Results The overall 5-year TVF rate was 14.9%, with 7.0% being related to the study stent. Cardiac death, MI and TVR related to the study stent occurred in 0.5%, 3.2%, and 5.7%, respectively. Stent thrombosis through 5-year follow-up was 1.0%. The rates of overall and study stent related TVF were numerically higher in patients with medically treated diabetes, long lesions (>= 28 mm), and small diameter vessels (<= 2.5 mm) compared to the overall study population. Additionally, favorable stent thrombosis rates through 5 years were reported for the PROMUS Element stent in these high-risk subgroups. Conclusions The final 5-year data from the PE-PROVE study demonstrate favorable outcomes and low rates of adverse events with the PE stent when used in "real-world" patients with coronary artery disease.
