CONTEXT Enoxaparin has demonstrated advantages over unfractionated heparin in low- to moderate-risk patients with non-ST-segment elevation acute coronary syndromes (ACS) treated with a conservative strategy. OBJECTIVES To compare the outcomes of patients treated with enoxaparin vs unfractionated heparin and to define the role of enoxaparin in patients(More)
BACKGROUND 3-Hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) have effects that extend beyond cholesterol reduction. We used an angiotensin (Ang) II-dependent model to test the hypothesis that cerivastatin ameliorates cardiac injury. METHODS AND RESULTS We treated rats transgenic for human renin and angiotensinogen (dTGR)(More)
We compared embolectomy (when available) with thrombolysis in patients with shock and massive pulmonary embolism. 13 patients were operated on, 10 (77%) of whom survived. The inferior vena cava was routinely clipped. The 24 medically treated patients were given alteplase until systemic and pulmonary artery pressures stabilised and heparin thereafter; 16(More)
BACKGROUND Optimal timing for an early invasive strategy in patients with non-ST-segment-elevation acute coronary syndrome remains unclear. We evaluated the relationship between time from hospital admission to coronary angiography and outcomes in high-risk patients with non-ST-segment-elevation acute coronary syndrome who underwent angiography within 48(More)
BACKGROUND Urokinase (uPA) and the urokinase receptor (uPAR) form a multifunctional system capable of concurrently regulating pericellular proteolysis, cell-surface adhesion, and mitogenesis. The role of uPA and uPAR in directed proteolysis is well established and its function in cellular adhesiveness has recently been clarified by numerous studies. The(More)
Tissue factor (TF), a main initiator of clotting, is up-regulated in vasculopathy. We tested the hypothesis that chronic in vivo angiotensin (ANG) II receptor AT(1) receptor blockade inhibits TF expression in a model of ANG II-induced cardiac vasculopathy. Furthermore, we explored the mechanisms by examining transcription factor activation and analyzing the(More)
BACKGROUND Novel antithrombotic agents such as hirudin have shown promise in the therapy of acute coronary syndromes. PEG-hirudin (polyethyleneglycol conjugated hirudin) has been developed to provide a longer plasma half-life and more stable antithrombotic plasma levels. Privious trials indicated a narrow therapeutic window for hirudin and a number of aPTT(More)
OBJECTIVE To investigate the relation between access to a cardiac catheterisation laboratory and clinical outcomes in patients admitted to hospital with suspected acute coronary syndrome. DESIGN Prospective, multinational, observational registry. SETTING Patients enrolled in 106 hospitals in 14 countries between April 1999 and March 2003. PARTICIPANTS(More)
Bleeding has recently emerged as an important outcome in the management of acute coronary syndromes (ACS), which is relatively frequent compared with ischaemic outcomes and has important implications in terms of prognosis, outcomes, and costs. In particular, there is evidence that patients experiencing major bleeding in the acute phase are at higher risk(More)
