Evaluation of a new, rapid bedside test for quantitative determination of B-type natriuretic peptide.
Y. Fischer,Karsten Filzmaier,H. Stiegler,J Graf,Simone Fuhs,Andreas Franke,Uwe Janssens,Axel M. Gressner +7 more
TL;DR: The Triage BNP test is an immunofluorometric assay for quantitative determination of BNP in EDTA-anticoagulated whole blood or plasma and the concentration of B NP in the specimen is proportional to the fluorescence bound to the detection lane, which is determined quantitatively by a handheld fluorescence instrument.

Selective increase of cardiac neuronal sympathetic tone: a catheter-based access to modulate left ventricular contractility.
Markus Zarse,Jurgita Plisiene,Karl Mischke,Thomas Schimpf,Christian Knackstedt,Felix Gramley,Georg Mühlenbruch,Mathias Waldmann,Michael Schmid,Nima Hatam,J Graf,Dirk Schuster,Peter Hanrath,Dainius H. Pauza,Patrick Schauerte +14 more
TL;DR: The neural adrenergic tone to the heart can be selectively increased by catheter stimulation of cardiac efferent sympathetic nerves, and positive inotropic effects persisted for 12 h of continued SNS.

Three-dimensional echocardiographic determination of left ventricular volumes and function by multiplane transesophageal transducer: dynamic in vitro validation and in vivo comparison with angiography and thermodilution
Harald P. Kühl,Andreas Franke,Uwe Janssens,Marc W. Merx,J Graf,Winfried Krebs,Helmut Reul,Günter Rau,Rainer Hoffmann,Heinrich G. Klues,Peter Hanrath +10 more
TL;DR: 3-dimensional echocardiography by multiplane transesophageal transducer for the determination of left ventricular volumes and ejection fraction in an in vitro experiment and in vivo with biplane angiography and the continuous thermodilution method was validated.

Value of SOFA (Sequential Organ Failure Assessment) score and total maximum SOFA score in 812 patients with acute cardiovascular disorders
Uwe Janssens,Robert Dujardin,J Graf,Wolfgang Lepper,Jan R. Ortlepp,Marc W. Merx,Markus Zarse,Thorsten Reffelmann,Peter Hanrath +8 more
TL;DR: IT and IV lidocaine given after 5 min of HCl application had a beneficial effect on the haemodynamic and arterial blood gas values in acute lung injury in rabbits model.
QRS prolongation on surface ECG and brain natriuretic peptide as indicators of left ventricular systolic dysfunction
TL;DR: Whether the combination of prolonged QRS duration and brain natriuretic peptide levels predicts left ventricular systolic dysfunction (LVSD) with a higher accuracy compared with Q RS duration or BNP alone is investigated.
