    Abstract:
    BACKGROUND: The paclitaxel drug-eluting stent (Taxus, Boston Scientific) is FDA approved for treatment of coronary artery disease in simple, noncomplex coronary lesions. In this registry, we sought to investigate the procedural success and long-term outcomes of patients receiving the Taxus stent in the setting of acute ST-elevation myocardial infarction (STEMI) in a busy single-center interventional program. METHODS: This is a single-center retrospective analysis of prospectively collected in-hospital data with postdischarge follow-up achieved by phone calls and review of medical records. Data were audited by an independent monitor, and outcomes were adjudicated by an experienced interventional cardiologist. All patients with STEMI over the period of 2 years (2005 and 2006) with native de novo lesions who received the Taxus stent were included. Patients receiving bare metal stents were excluded. The primary outcome was the combined end point of cardiac death, recurrent nonfatal MI, and target lesion revascularization (TLR) on follow-up. RESULTS: Of 198 patients included in this study, follow-up data were obtained in 172 (86.9%) patients. The mean age was 63+/-14.9 years. There were 59.1% males. Patients had the following cardiac risk factors: diabetes 20.7%, hypertension 60.6%, hyperlipidemia 87.8%, and current smoking 48%. In-hospital complications included death 5.1%, acute closure with stent thrombosis 1%, vascular complications 2.9%, and cardiogenic shock 6.6%. The mean follow-up period (days) was 317.3+/-239.3. The primary end point of cardiac death, nonfatal MI, and TLR was met in 12.4%. Individual end points on follow-up were cardiac death 2.5%, total death 4.9%, TLR 8.1%, target vessel revascularization 19.9%, stroke 1.2%, nonfatal MI 5%, and acute stent thrombosis 5.5% (definite 4.3%, probable 0.6%, possible 0.6%; Academic Research Consortium definition). CONCLUSION: The use of the Taxus stent in acute STEMI is associated with a low postdischarge combined end point of cardiac death, nonfatal MI, and TLR and a definite/probable 4.9% in-stent thrombosis rate, which is within the reported range of data published in "real-world" registry.
