BACKGROUND Clopidogrel and aspirin are the most commonly used antiplatelet therapies for percutaneous coronary intervention (PCI). We assessed the effect of various clopidogrel and aspirin regimens in prevention of major cardiovascular events and stent thrombosis in patients undergoing PCI. METHODS The CURRENT-OASIS 7 trial was undertaken in 597 centres(More)
OBJECTIVE To describe and outline audit and quality control activities of the multicentre interventional and cardiac surgery registry in Victoria as a potential model for a national registry. DESIGN, SETTING, AND PATIENTS The Melbourne Interventional Group (MIG) database is a prospective multicentre registry recording consecutive percutaneous coronary(More)
Spontaneous coronary artery dissection (SCAD) is an uncommon condition that may lead to sudden coronary artery occlusion resulting in a fatal acute myocardial infarction. It usually affects young to middle age women. A Medline search from 1966 to 2001 (using keywords: coronary artery dissection and systemic lupus erythematosis) revealed no prior reports of(More)
BACKGROUND Major bleeding is a serious complication of percutaneous coronary intervention (PCI). We set out to investigate the incidence of major bleeding and its impact on hospitalisation and long-term mortality. METHOD We examined seven years of registry data encompassing 16,860 PCI procedures. RESULTS Between 2005 and 2011 major bleeding increased(More)
BACKGROUND The Washington Radiation for In-Stent Restenosis Trial for long lesions (Long WRIST) was designed to determine the safety and efficacy of vascular brachytherapy for the treatment of diffuse in-stent restenosis. METHODS AND RESULTS A total of 120 patients with diffuse in-stent restenosis in native coronary arteries (lesion length, 36 to 80 mm)(More)
Recent reports suggest that drug-eluting stents (DESs) may increase the risk of stent thrombosis (ST) relative to bare-metal stents (BMSs). Therefore, the aim of this study was to compare DES and BMS outcomes with a specific focus on ST. We analyzed 30-day and 1-year outcomes of 2,919 patients who underwent percutaneous coronary intervention with stent(More)
BACKGROUND Intracoronary radiation therapy (IRT) is the only proven treatment for in-stent restenosis (ISR). It is, however, associated with a significant failure rate. The present study evaluated the outcomes of patients who underwent repeat intracoronary radiation for recurrent ISR. METHODS AND RESULTS Fifty-one consecutive patients who failed a(More)
BACKGROUND Intracoronary gamma-radiation reduces recurrent in-stent restenosis (ISR). Late thrombosis was attenuated with 6 months of aspirin and clopidogrel. We aimed to find out whether 12 months of aspirin plus clopidogrel is superior to a strategy of 6 months after radiation therapy for patients with ISR. METHODS AND RESULTS One hundred twenty(More)
Prolonged dual antiplatelet therapy with aspirin and clopidogrel is mandatory after drug-eluting stent (DES) implantation because of potential increase risk of stent thrombosis compared to bare-metal stents. As more DES are being implanted, many of these patients will undergo non-cardiac surgery whilst on antiplatelet therapy. The optimal management of(More)
Prolonged dual-antiplatelet therapy with aspirin and clopidogrel is mandatory after drug-eluting stent implantation because of the potential increased risk of late stent thrombosis. The concern regarding prolonged antiplatelet therapy is the increased risk of bleeding. Gastrointestinal bleeding is the most common site of bleeding and presents a serious(More)
