title: Coronary in-stent restenosis in diabetic patients after implantation of sirolimus or paclitaxel drug-eluting coronary stents.
abstract: It is now emerging that, in patients who are at high risk for cardiovascular complications and, in particular, those with diabetes, the occurrence of late restenosis and thrombosis after treatment of coronary artery disease with drug-eluting stents is higher than earlier reports have suggested. Therefore, the aim of this study was to assess the prevalence of in-stent restenosis in a cohort of consecutive patients with diabetes treated for coronary disease in 2005 with drug-eluting stents [either sirolimus (58%) or paclitaxel (42%)]. The duration of follow-up was 9.0+/-3.4 months [mean+/-1 standard deviation (S.D.)]. A total of 154 patients (type 2 diabetes: 91%) were included in the study (age: 66+/-10 years), and the total number of implanted stents was 184. Two subjects died from cardiac causes, while myocardial infarction and (un)stable angina were observed in 3 (2%) and 39 (25%) patients, respectively. In-stent restenosis, appraised by angiography, was observed in 17 individuals (11%) after a mean follow-up of five months. Mean HbA(1c) in patients with restenosis was 7.6+/-1.8%. There was no difference in the rate of restenosis with sirolimus-(n=8) compared with paclitaxel-(n=9) eluting stents. Male gender, oral therapy for diabetes and stent diameter were predictors of in-stent restenosis. In conclusion, even over a medium-term period, in-stent restenosis remains a potential risk for coronary diabetic patients treated with drug-eluting devices.
