Paclitaxel-eluting balloon angioplasty and cobalt-chromium stents versus conventional angioplasty and paclitaxel-eluting stents in the treatment of native coronary artery stenoses in patients with diabetes mellitus

Abstract

Aims: Coronary lesions in diabetics (DM) are associated with a high recurrence following percutaneous coronary intervention (PCI), even after drug-eluting stent (DES) deployment. Encouraging clinical data of the drug-eluting balloon catheter (DEB) SeQuent Please warrant its investigation in these patients. Methods and results: Eighty-four diabetic patients (60.8±9.1years, 76.2% male) were randomised to either the DEB SeQuent™ Please or the DES Taxus™ Liberte™ to compare the 9-month clinical and angiographic outcome of PCI in native coronary arteries. Comparing the DEB vs. the DES the 9-month results (follow-up DEB 39/45 [86.7%], DES 36/39 [92.3%] ) are statistically not different at the 0.05 level for the primary end- point of in-segment (0.37±0.59 mm vs. 0.35 ±0.63 mm) and in-stent (0.51±0.61 mm vs. 0.53±0.67 mm) late lumen loss, overall and cardiac deaths (2/45 [4.4%] and 3/45 [6.7%] vs. 0), target lesion revascularisation (3/45 [8.9%] vs. 4/39 [10.3%] ), the total MACE rate (6/45 [13.3%] vs. 6/39 [15.4%] ), and the event free survival after 10.2±3.8 months (Kaplan-Meier analysis, p < 0.80, log rank test). Conclusions: The clinical and angiographic outcome of the combination of the drug-eluting balloon SeQuent Please with a cobalt chromium stent compared to the drug eluting Taxus stent are similar. © Europa Edition 2011.
