We prospectively evaluated all patients admitted to our coronary care unit during 1993 with ischemic chest pain but without ST-segment elevation on the presenting electrocardiogram, and determined the influence of the extent of ST-segment depression, measured using calipers and blinded to the outcome, on 4-year survival. The presenting symptoms of 367(More)
Retrograde transport of horseradish peroxidase (HRP) was used to characterise the soma and dendritic arborization of retinal ganglion cells in adultXenopus laevis toad. HRP was administered to the cut end of the optic nerve and the morphological characteristics of HRP-filled ganglion cells were analysed in retinal wholemount preparations using computer(More)
BACKGROUND Early resolution of ST-segment elevation (ST-segment recovery) is associated with an improved outcome after infarction. Whether this relation is present in patients with Thrombolysis In Myocardial Infarction (TIMI) grade 2 or 3 flow (ie, patent) infarct-related arteries is not known. METHODS AND RESULTS To examine the associations between time(More)
OBJECTIVES To evaluate the corrected Thrombolysis in Myocardial Infarction (TIMI) frame count (CTFC) as a predictor of late survival after myocardial infarction. BACKGROUND Thrombolysis in Myocardial Infarction flow grades predict late survival after myocardial infarction. The CTFC provides a more reproducible measurement of infarct-related artery blood(More)
OBJECTIVE To assess whether the 90 minute corrected thrombolysis in myocardial infarction frame count (CTFC) in the infarct related artery predicts left ventricular function at 48 hours in patients with myocardial infarction treated with aspirin, streptokinase, and either heparin or Hirulog. DESIGN AND SETTING Analysis of 251 patients with acute(More)
BACKGROUND Traditionally patients who indicate that they have a heart murmur or who indicate that they have had rheumatic fever are given antibiotic prophylaxis for dental treatment. This is commonly done without further assessment of the patient's actual endocarditis risk. Echocardiography is a non-invasive method of assessing cardiac valve function and(More)
Some cardiac conditions require antibiotic prophylaxis for some types of dental treatment to reduce the risk of infective endocarditis (IE). All medical and dental practitioners are familiar with this practice but tend to use different regimens in apparently similar circumstances. Generally, the trend has been to prescribe antibiotics if in doubt. This(More)
MXM modules, used to package graphics processing devices for use in benign environments, have been tested for use in harsh environments typical of deployed defense and aerospace systems. Results show that specially mechanically designed MXM GP-GPU modules can survive these environments, and successfully provide the enormous processing capability offered by(More)
Acute ischaemic coronary syndromes, the clinical sequelae of thrombosis over a fissured atherosclerotic plaque within the coronary circulation, are the leading cause of death and hospitalisation in Western countries. Platelets are fundamental for the initiation and continuation of thrombosis, and currently available anti-platelet agents such as aspirin(More)
