Angiographic Outcome in Multivessel Disease (GABI II Study) Using New Coronary Device Interventions and Comparison with GABI I Trial Results.

摘要

Percutaneous coronary interventions using stents were investigated in patients with multivessel disease. Acute and long-term results were compared with those of the German Angioplasty Bypass Surgery Investigation trial in a prospective multicenter study. The study included 134 patients in whom 277 lesions were treated. Angiographic success and procedural success were achieved in 268 of 277 lesions (97%) and 118 of 134 patients (88%), respectively. Control angiography performed in 90 of 118 eligible patients (76%) exhibited restenosis in 43 of 182 lesions (24%). Multivariate regression analysis found that a diffuse lesion, the lesion and stent length, and the final luminal diameter were predictive for restenosis. Thus, immediate and long-term results of multivessel coronary intervention utilizing stents were improved compared to percutaneous transluminal coronary angioplasty of multivessel lesions. However, there is still need for improvement of long-term results, especially in particular lesion subgroups. Copyright 2004 S. Karger AG, Basel
