OBJECTIVE To define the phenotype and function of CD4+,CD25+ regulatory T cells (Treg) in patients with cutaneous lupus erythematosus (CLE), a heterogeneous autoimmune disease characterized primarily by inflammatory skin lesions. METHODS The number of Treg in skin specimens obtained from patients with various subtypes of CLE was investigated by(More)
BACKGROUND This study evaluated the wearable cardioverter-defibrillator (WCD) for use and effectiveness in preventing sudden death caused by ventricular tachyarrhythmia or fibrillation. METHODS From April 2010 through October 2013, 6043 German WCD patients (median age, 57 years; male, 78.5%) were recruited from 404 German centers. Deidentified German(More)
BACKGROUND Right ventricular (RV) shape and function serves as an indicator in several types of heart disease such as arrhythmogenic right ventricular dysplasia (ARVD). However, there is no in-depth knowledge of RV motion, even in healthy subjects. The aim of our study was to provide a quantitative analysis of normal variations in RV wall motion in healthy(More)
A growing body of evidence suggests a pivotal role of inflammatory processes in AF in a bidirectional manner. Infiltrating leukocytes seem to promote both structural and electrical remodelling processes in patients with AF. Monocyte-platelets-aggregates (MPAs) are sensitive markers of both platelets and monocyte activation. So far it is not clear whether(More)
INTRODUCTION After cardiac arrest due to acute coronary syndromes (ACS) therapeutic hypothermia (HT) is the standard care to reduce neurologic damage. Additionally, the concomitant medical treatment with aspirin and a P2Y12 receptor inhibitor like clopidogrel (Cl), prasugrel (Pr) or ticagrelor (Ti) is mandatory. The platelet inhibitory effect of these drugs(More)
BACKGROUND While impact of surgical aortic valve replacement (SAVR) on the function of the right and left ventricle (RV, LV) has been studied extensively, the objective of this study was to compare the two different transcatheter approaches, transfemoral vs. transapical aortic valve implantation (tf-AVI, ta-AVI) and SAVR with respect to postoperative(More)
OBJECTIVE Hypoxia plays a pivotal role in development and progression of restenosis after vascular injury. Under hypoxic conditions the hypoxia-inducible factors (HIFs) are the most important transcription factors for the adaption to reduced oxygen supply. Therefore the aim of the study was to investigate the effect of a local HIF-inhibition and(More)

Atrial fibrillation (AF) is known to cause platelet activation. AF and its degree of thrombogenesis could be associated with monocyte-platelet aggregates (MPAs). We investigated on whether the content of MPAs or other platelet activation markers is associated with the recurrence of AF after pulmonary vein isolation (PVI). A total of 73 patients with(More)
