The role of hemostatic markers as venous stenosis or occlusion predictors following first transvenous cardiac device implantation.

Background: Among patients with an implanted cardiac implantable electronic device (CIED), ipsilateral upper extremity vein stenosis or occlusion (VSO) is observed more frequently than in the general population. However, there are no data available concerning the relationship between hemostatic markers (and their dynamics) and the occurrence of VSO. The aim of this study was to assess the predictive value of beta-thromboglobulin, the von Willebrand factor (vWF), fibrynogen and D-dimer for VSO development among first time CIED recipients.

Predictors of venous stenosis or occlusion following first transvenous cardiac device implantation: Prospective observational study.

Introduction: Venous stenosis or occlusion related to an intracardiac device is a well-known complication of that procedure. There are numerous studies tried to determine predictors of venous stenosis or occlusion; however, most of them investigate the venous system prior to device upgrade, generator replacement, or transvenous lead extraction. Therefore, we aimed to assess the prevalence and determine the predictors of venous stenosis or occlusion following first transevnous cardiac device implantation.

Changes in the central and peripheral circulatory system in response to the cold: own studies using impedance plethysmography and Doppler ultrasound.

The aim of the study was to determine the cardiovascular response to continuous (4 °C for 60 min) and intermittent (10 min at 4 °C and 10 min at room temperature alternately) exposure to the cold in 30 healthy young men. The subjects were equipped with a set of identical clothing (insulation 2.1 clo) and during the stay in the chamber and outside performed the same activities, i.
