Flow-mediated vasodilation (FMD) of systemic arteries, a non-invasive parameter of endothelial function, is correlated with cardiovascular risk factors. The relationship between FMD and morphologically and clinically evident coronary artery disease has not been described. This study was performed to test the hypothesis that an impairment of FMD in the(More)
BACKGROUND Combined intracoronary and intramyocardial administration might improve outcomes for bone-marrow-derived stem cell therapy for acute myocardial infarction (AMI). We compared the safety and feasibility of early and late delivery of stem cells with combined therapy approaches. METHODS Patients with left ventricular ejection fraction less than 45%(More)
To evaluate the potential of magnetic resonance imaging (MRI) in detection and quantification of mitral regurgitation, 26 pts. with echocardiographically or angiographically documented mitral regurgitation were examined using a 0.5 Tesla superconducting magnet. In each patient a multislice-multiphase study in a sagittal-coronal double angulated projection(More)
BACKGROUND In the setting of primary percutaneous coronary intervention, patients with a chronic total occlusion in a non-infarct related artery were recently identified as a high-risk subgroup. It is unclear whether ST-elevation myocardial infarction patients with a chronic total occlusion in a non-infarct related artery should undergo additional(More)
BACKGROUND Post-transplant follow-up of heart transplant patients consists of repeated coronary angiography, which is associated with high costs, discomfort and risk. We sought to determine whether multislice computed tomography (MSCT) permits the exclusion or progression of coronary artery disease in heart transplant patients. METHODS MSCT scanning(More)
BACKGROUND In current clinical practice, 35-67% of significant coronary artery lesions are located in small (<3.0 mm) vessels, a setting with poor short- and long-term results after percutaneous coronary interventions. OBJECTIVES The aim of the present Arthos Pico Austria Multicenter Registry is to demonstrate the safety and efficacy of the Arthos Pico(More)
Parathyroid hormone (PTH) regulates the content of calcium and thus exerts an effect on myocardial function. Abnormal secretion of PTH has been sporadically reported to be associated with depressed mechanical performance of the heart muscle. In the present study, we first measured PTH levels at baseline in 27 consecutive patients with advanced congestive(More)
BACKGROUND To evaluate initial multicenter results with minimally invasive transapical aortic valve implantation (TAP-AVI) for high risk patients with aortic stenosis. METHODS AND RESULTS TAP-AVI was performed via a small anterolateral minithoracotomy with or without femoro-femoral extracorporeal circulation (ECC) on the beating heart. A pericardial(More)
OBJECTIVES The aim of this study was to perform an investigation of the effects of the longitudinal straightening of coronary arteries by stents and the possible association with major adverse cardiac events (MACE) (primary end point) and angiographic restenosis (secondary end point). BACKGROUND Stent deployment straightens a tortuous artery, and any(More)
