Abstract:

With stenting, restenosis occurs in ~ 25% of patients and the incidence is even higher in patients with diabetes, small coronary vessels and long lesions. The sirolimus-eluting balloon-expandable stent in the treatment of patients with de novo native coronary-artery lesions (SIRIUS) trial, enrolled patients with more challenging conditions, including a higher frequency of diabetes, more complex lesion morphology and longer lesions and showed benefits in all groups. After 240 days, the frequency of stenosis of at least 50% of the luminal diameter was 3.2 and 35.4% in the sirolimus and standard stents groups, respectively. The TAXUS-IV trial was the first large-scale trial on the safety and efficacy of paclitaxel-eluting stents in a broad population of patients and lesions, and established the safety and effectiveness of this agent. After 9 months, there was a mean stenosis of 17% in the paclitaxel group compared to 37% of patients treated with a bare stent. Thus, the local delivery of potent cell cycle inhibitors (sirolimus, paclitaxel) from stents being used for revascularisation dramatically decreases the incidence of restenosis in the populations of patients studied so far and represents a major advancement in the treatment of coronary artery disease.
