Abstract AR
Background & Objectives .: Angiographic restenosis has been reported in 50% of patients within 6 months after balloon angioplasty.
Although stent implantation has been shown to reduce restenosis as compared with percutaneous transluminal coronary angioplasty, in-stent restenosis (ISR) still occurs in 10-30% of the patients.
Drug-eluting stents containing the immunosuppressive agent rapamycin and the anti-mitotic agent paclitaxel have shown encouraging reductions in restenosis in de novo lesions, and possibly in in-stent restenosis lesions.
The goal of this study was to compare the restenosis rates in two coronary stent systems using rapamycin and paclitaxel.
Methodt: This observational study was conducted in the Cardiology Department at the Essen University Hospital, Germany.
A total of 106 consecutive patients received either rapamycin eluting stents (n=54) or paclitaxel stents (n=52) and underwent angiographic follow-up between August 2002 and February 2004.
All the patients received a daily dose of 100 mg aspirin indefinitely and 300 mg clopidogrel as a loading dose before the intervention and a daily dose of 75 mg for 6 months after the intervention.
The primary endpoint was diameter stenosis percentage at follow-up.
The secondary angiographic endpoints included late loss, binary restenosis, and minimal lumen diameter at follow-up.
The secondary clinical endpoints included the incidence of death, the need for bypass surgery or intervention to treat restenosis of the target lesions, myocardial infarction (Q wave or non Q wave), target vessel revascularization, and target lesion revascularization.
Results: The diameter stenosis (DS%) at follow-up with the rapamycin eluting stent was 25.11+ 18.24% vs.
25.90±21.23% for the paclitaxel stent;P=0.83.
Minimal lumen diameter at follow- rapamycin stent vs.
2.34+0.72 mm for the paclitaxel stent, P=0.57.
Binary restenosis was detected in 7 patients (12.9%) in the rapamycin group compared with 8 patients (15.3%) in the paclitaxel group (P=0.65).
Late loss was similar between the two groups.
No patients in either group suffered from M (Q wave or non Q wave) during follow-up.
The incidence of death was 0% in the both groups.
Coronary bypass surgery was not performed on any patient in the two groups.
Target lesion revascularization and target vessel revascularization were similar in the two groups.
Conclusion: In this observational study, we did not observe significant differences between the rapamycin-coated stent and the paclitaxel-coated stent in terms of follow-up angiographic parameters as well as clinical events.
