BACKGROUND Vagus nerve stimulation has been successfully used as a treatment strategy for epilepsy and affective disorders for years. Transcutaneous vagus nerve stimulation (tVNS) is a new non-invasive method to stimulate the vagus nerve, which has been shown to modulate neuronal activity in distinct brain areas. OBJECTIVES Here we report effects of tVNS(More)
The benefit of carotid endarterectomy in symptomatic high-grade stenosis has long been proven. The role of angioplasty as an alternative is still a matter of debate. We compared the occurrence of intraprocedural microembolic signals and ischemic lesions between carotid endarterectomy (CEA) and carotid angioplasty with stent placement (CAS) without a(More)
BACKGROUND The complex anatomy of the aortic annulus warrants the use of three dimensional (3D) modalities for prosthesis sizing in transcatheter aortic valve implantation (TAVI). Multislice computed tomography (MSCT) has been used for this purpose, but its use may be restricted because of contrast administration. 3D transesophageal echocardiography(More)
BACKGROUND Genome-wide association studies (GWAS) are useful to reveal an association between single nucleotide polymorphisms and different measures of obesity. A multitude of new loci has recently been reported, but the exact function of most of the according genes is not known. The aim of our study was to start elucidating the function of some of these(More)
AIMS Plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) is a strong biochemical marker of heart failure and left ventricular dysfunction (LVD). Due to renal arterio-venous clearance of NT-proBNP and the correlation of plasma concentrations with renal function, we hypothesized that NT-proBNP may have potential as a urinary marker. The objective of(More)
BACKGROUND High-sensitive Troponin I (hsTnI) facilitates the early diagnosis of myocardial infarction (MI). However, since hsTnI has not been well characterized in non-ischemic cardiac conditions, the predictive value of hsTnI for MI remains unclear. METHODS hsTnI (ADVIA Centaur, Siemens) on admission was analyzed in 929 patients with acute cardiac(More)
Heart failure causes electrophysiological changes in the heart. Downregulation of repolarizing K+-currents leads to a prolongation of the cardiac action potential. Nevertheless, little is known about the differential expression of atrial and ventricular K+-channels in the failing heart. Ten rabbits underwent progressive rapid right ventricular pacing for 30(More)
BACKGROUND/OBJECTIVES Molecular mechanisms of congestive heart failure as reflected by alterations of protein expression patterns are still incompletely analyzed. We therefore investigated intraventricular (ie, left ventricular congestive heart failure [LV-CHF] vs. LV-control [CTRL], and right ventricular [RV]-CHF vs. RV-CTRL) and interventricular (ie,(More)
Splanchnic vasodilation is the pathophysiological hallmark in the development of the hyperdynamic circulatory syndrome in liver cirrhosis and portal hypertension. This has been attributed so far mainly to a marked vascular hyporeactivity to endogenous vasoconstrictors. However, myogenic tone and vessel stiffness have not been addressed in mesenteric(More)
BACKGROUND Aldosterone is an important mediator of cardiovascular and renal remodeling. Type II diabetes mellitus leads to renal and cardiac end organ damage. We investigated the renin-angiotensin-aldosterone system in a model of type 2 diabetes mellitus with known diabetic nephropathy and cardiac remodeling, the Zucker Diabetic Fatty rat with and without(More)
