Non-thrombotic PE does not represent a distinct clinical syndrome. It may be due to a variety of embolic materials and result in a wide spectrum of clinical presentations, making the diagnosis difficult. With the exception of severe air and fat embolism, the haemodynamic consequences of non-thrombotic emboli are usually mild. Treatment is mostly supportive(More)

OBJECTIVES The present study investigated current management strategies as well as the clinical course of acute major pulmonary embolism. BACKGROUND The clinical outcome of patients with acute pulmonary embolism who present with overt or impending right heart failure has not yet been adequately elucidated. METHODS The 204 participating centers enrolled(More)
BACKGROUND The role of fibrinolytic therapy in patients with intermediate-risk pulmonary embolism is controversial. METHODS In a randomized, double-blind trial, we compared tenecteplase plus heparin with placebo plus heparin in normotensive patients with intermediate-risk pulmonary embolism. Eligible patients had right ventricular dysfunction on(More)
OBJECTIVE Human obesity is associated with elevated leptin levels and a high risk of death from cardiovascular disease. In the present study, we investigated the effects of leptin on vascular wound healing and arterial lesion growth in mice. METHODS AND RESULTS Wild-type mice placed on an atherogenic, high-fat diet had elevated (9-fold) leptin levels(More)
BACKGROUND Brain natriuretic peptide (BNP) and N-terminal (NT)-proBNP have recently emerged as promising parameters for risk assessment in acute pulmonary embolism (PE). However, their positive predictive value is low, and the prognostic implications of NT-proBNP or troponin elevation alone are questionable. METHODS AND RESULTS To determine whether the(More)
Obesity is associated with increased cardiovascular morbidity and mortality and with elevated circulating levels of the satiety factor leptin. This study provides evidence for a direct link between leptin and the risk for thrombotic complications in obese individuals. For example, although arterial injury provokes thrombosis in both lean and obese (ob/ob)(More)
Copyright © 2008 Massachusetts Medical Society. A 62-year-old man presented with a 5-day history of progressively worsening dyspnea and orthopnea after returning from a 3-day business trip to the Far East. On physical examination, the heart rate was 102 beats per minute, and the blood pressure 110/60 mm Hg. The arterial oxygen saturation was 86% while the(More)
AIMS We investigated the value of a novel early biomarker, heart-type fatty acid-binding protein (H-FABP), in risk stratification of patients with acute pulmonary embolism (PE). METHODS AND RESULTS We prospectively included 107 consecutive patients with confirmed PE. The endpoints were (i) PE-related death or major complications and (ii) overall 30-day(More)
AIMS To assess the role of cardiac troponin T (cTnT) levels on admission using a new, highly sensitive assay (hsTnT) in the risk assessment of normotensive patients with acute pulmonary embolism (PE). METHODS AND RESULTS We prospectively studied 156 consecutive normotensive patients with confirmed PE. The prognostic value of hsTnT at baseline was compared(More)
