AIMS This article summarizes all available published data with respect to clinical success, complications, and outcomes of endovascular stent-graft placement among patients with descending aortic dissection (AD). METHODS AND RESULTS We performed a meta-analysis of all published series on retrograde endovascular stent-graft placement encompassing >or=3(More)
AIMS To analyse the prevalence, and diagnostic and therapeutic consequences, of accidental findings in electron-beam tomographic scans performed for evaluation of coronary artery calcification. METHODS AND RESULTS A total of 1812 consecutive patients with known or suspected coronary artery disease underwent electron-beam tomography. In 583 (32%) of the(More)
OBJECTIVES The purpose of this study was to determine net reclassification improvement (NRI) and improved risk prediction based on coronary artery calcification (CAC) scoring in comparison with traditional risk factors. BACKGROUND CAC as a sign of subclinical coronary atherosclerosis can noninvasively be detected by CT and has been suggested to predict(More)
PURPOSE To measure the effective radiation doses delivered at electron-beam computed tomography (CT) and multi-detector row spiral CT of coronary arteries and to compare these doses with those delivered at catheter coronary angiography. MATERIALS AND METHODS An anthropomorphic phantom equipped with 66 thermoluminescent dosimeters was imaged at cardiac CT.(More)
The Heinz Nixdorf Recall Study is an ongoing population-based prospective cardiovascular cohort study of the Ruhr area in Germany. This paper focuses on the recruitment strategy and its response results including a comparison of participants of the baseline examination with nonparticipants. Random samples of the general population were drawn from residents'(More)
AIMS The rise of markers for myocardial injury indicates early graft-related or non-graft-related perioperative myocardial infarction (PMI) after coronary artery bypass grafting (CABG). A diagnostic discrimination between these two situations may enable adequate therapeutic measures, limiting myocardial damage, and improving outcome. METHODS AND RESULTS(More)
OBJECTIVES The purpose of this research was to assess the value of systemic inflammatory biomarkers in the detection of acute aortic dissection (AD). BACKGROUND Rapid diagnosis and initiation of treatment is pivotal for patients with acute AD. So far, there is no laboratory test to aid the diagnosis. METHODS Plasma fibrin D-dimers, white blood cell(More)
PURPOSE To quantify left ventricular function and mass derived from retrospectively ECG-gated 64-detector-row computed tomography coronary angiography data sets in comparison to cine magnetic resonance (MR) imaging as the reference standard. We hypothesized that the administration of beta-blockers prior to multidetector computed tomography (MDCT) coronary(More)
BACKGROUND Long-term exposure to urban air pollution may accelerate atherogenesis, but mechanisms are still unclear. The induction of a low-grade systemic inflammatory state is a plausible mechanistic pathway. OBJECTIVES We analyzed the association of residential long-term exposure to particulate matter (PM) and high traffic with systemic inflammatory(More)
AIM Coronary artery calcification (CAC), as a sign of atherosclerosis, can be detected and progression quantified using computed tomography (CT). We develop a tool for predicting CAC progression. METHODS AND RESULTS In 3481 participants (45-74 years, 53.1% women) CAC percentiles at baseline (CACb) and after five years (CAC₅y) were evaluated, demonstrating(More)
