Background— Experimental studies suggest that deferoxamine (DFO) limits the generation of reactive oxygen species by chelating redox-active iron and thereby may reduce ischemia-reperfusion injury myocardial infarct (MI) size. We investigated whether DFO administered before reperfusion primary percutaneous coronary intervention (PPCI) would ameliorate oxidative stress MI Methods Results— randomly assigned 60 patients with ST-elevation–MI to receive an intravenous bolus (500 mg) immediately...

Objective: We aimed to assess the pattern of use drug-eluting stents (DESs) in patients undergoing percutaneous coronary interventions (PCIs) Victorian public hospitals. Design, setting and patients: Prospective study comparing one or more DESs versus bare-metal (BMSs) only, consecutive 2428 PCIs with stent implantation from 1 April 2004 31 December 2005 at seven Main outcome measures: Adherence current Department Human Services guidelines which recommend DES high-risk features for...

To evaluate outcomes of patients undergoing rotational atherectomy (RA) in a multicenter percutaneous coronary intervention (PCI) registry.RA remains an important technique for plaque modification PCI, particularly with complex calcification.The study population consisted consecutive PCI nine major Australian hospitals, who were treated over 8-year period (June 2004 to June 2012).Of 16,577 PCI's, 1.0% n = 167 (214 lesions) underwent RA. Patients RA more likely be older (71.0 ± 9.7 vs. 64.4...

Increasing transcatheter aortic valve implantation (TAVI) rates have resulted in prolonged waiting times. These been associated with heart failure hospitalizations (HFH) and mortality yet sex differences not reported.All patients who underwent TAVI for severe stenosis at a tertiary referral hospital Australia were prospectively included. Total time was divided into 'work-up' (period from date until team approval) and, 'procedural' approval procedure date). Patients analysed according to sex....

Abstract Aims Experimental studies demonstrate protective effects of doxycycline on myocardial ischaemia-reperfusion injury. The trial investigated whether administered prior to reperfusion in patients presenting with ST-elevation infarction (STEMI) reduces infarct size (IS) and ameliorates adverse left ventricular (LV) remodelling. Methods results In this randomized, double-blind, placebo-controlled trial, STEMI undergoing primary percutaneous coronary intervention (PPCI) were randomized...

<h3>Introduction</h3> Complications of tunnelled central venous catheters (CVCs) range from inconvenient to life threatening. Breakages the external portion can be repaired using a catheter specific repair kit which, when feasible, is preferable changing line. Breakage reported common but few studies have documented use and efficacy kits. At Glasgow Royal Infirmary we recently changed 9.6Fr Hickman lines © 6.6Fr Broviac thought kits were less efficacious. We carried out this study assess...
