AIMS Because of its high spatial resolution and tissue contrast, magnetic resonance imaging (MRI) was used to assess cardiac structure and function in a large population of patients with acute myocardial infarction (AMI). METHODS AND RESULTS One hundred and ten patients were studied by MRI 6.1 +/- 2.2 days after AMI. Infarct size (IS), persistent(More)
I mproved methods for detecting individual patients recovering from myocardial infarction who are at high risk for sudden cardiac death are essential for reducing mortality from ventricular arrhythmias. During the past decade, many investigators have recorded low-amplitude, high-frequency waveforms and altered frequency components in the terminal QRS(More)
Sufficient data are available to recommend the use of the high-resolution or signal-averaged electrocardiogram in patients recovering from myocardial infarction without bundle branch block to help determine their risk for developing sustained ventricular tachyarrhythmias. However, no data are available about the extent to which pharmacological or(More)
BACKGROUND Adipose tissue inflammation may play a critical role in the pathogenesis of insulin resistance (IR). The present study examined the role of lymphocytes in adipose tissue inflammation and IR. METHODS AND RESULTS In a mouse model of obesity-mediated IR, high-fat diet (HFD) induced IR already after 5 weeks, which was associated with a marked(More)
There is increasing evidence that complement activation may play a role in atherogenesis. Complement proteins have been demonstrated to be present in early atherosclerotic lesions of animals and humans, and cholesterol-induced atherosclerotic lesion formation is reduced in complement-deficient animals. Potential complement activators in atherosclerotic(More)
BACKGROUND LDL and C-reactive protein (CRP) are important cardiovascular risk factors. Both LDL and CRP deposit in the arterial wall during atherogenesis. Stranded LDL is taken up by macrophages, causing foam cell formation. Because native LDL does not induce foam cell formation, we hypothesized that CRP may opsonize native LDL for macrophages. METHODS(More)
To assess the effect of autologous bone-marrow cell (BMC) therapy in patients with acute myocardial infarction in a rigorous double-blind, randomized, placebo-controlled trial. Patients with reperfusion >6 hours after symptom onset were randomly assigned in a 2:1 ratio to receive intracoronary BMC or placebo therapy 5 to 7 days after symptom onset. The(More)
In patients with acute myocardial infarction (AMI), the number of transplanted autologous bone-marrow cells (BMC) has been linked to improvement in left ventricular ejection fraction (LVEF). Complete obstruction of myocardial microvasculature is indicated by microvascular obstruction (MO) in cardiac magnetic resonance imaging (CMR). We analyzed whether the(More)
Vascular Endothelial Growth Factor (VEGF) is a specific endothelial mitogen and an important angiogenic factor in vivo, capable of inducing therapeutic angiogenesis when administered to ischemic myocardium. Suramin, originally developed as an anti-trypanosomal agent, was recently shown to exert an antiangiogenic action. We have tested the hypothesis,(More)
OBJECTIVES During its German pilot phase, the EuroCMR (European Cardiovascular Magnetic Resonance) registry sought to evaluate indications, image quality, safety, and impact on patient management of routine CMR. BACKGROUND CMR has a broad range of applications and is increasingly used in clinical practice. METHODS This was a multicenter registry with(More)
