One key problem in modern medical imaging is linking measured data and actual physiological quantities. In this article we derive such a link between the electrical bioimpedance of lung parenchyma, which can be measured by electrical impedance tomography (EIT), and the magnitude of regional ventilation, a key to understanding lung mechanics and developing(More)
BACKGROUND Human-activated protein C (APC) is a serine protease with anticoagulant, anti-inflammatory and cytoprotective functions. This feature renders APC to be a promising vascular-inflammatory biomarker. OBJECTIVE The aim of the present study was the development and validation of a technique that allows the measurement of APC plasma levels under(More)
Levels of C-reactive protein (CRP), uric acid (UA), and total bilirubin (TB) are associated with coronary artery disease and major adverse cardiac events (MACEs) in patients with ST-segment elevation myocardial infarction (STEMI). We retrospectively included 1167 patients with STEMI who underwent percutaneous coronary intervention and routine blood(More)
INTRODUCTION Patients with acute respiratory distress syndrome (ARDS) typically show a high degree of ventilation inhomogeneity, which is associated with morbidity and unfavorable outcomes. Electrical impedance tomography (EIT) is able to detect ventilation inhomogeneity, but it is unclear which method for defining the region of interest (ROI) should be(More)
OBJECTIVE Takotsubo cardiomyopathy, also known as stress-induced cardiomyopathy (SCM) resembles a reversible cardiomyopathy that is characterized by localized wall motion abnormalities in the absence of stenotic coronary vascular disease. Patients typically present with apical ballooning of the left ventricle (LV), however the right ventricle (RV) is also(More)
PURPOSE OF REVIEW This review article summarizes the recent advances in electrical impedance tomography (EIT) related to cardiopulmonary imaging and monitoring on the background of the 30-year development of this technology. RECENT FINDINGS EIT is expected to become a bedside tool for monitoring and guiding ventilator therapy. In this context, several(More)
The global inhomogeneity (GI) index is a parameter of ventilation inhomogeneity that can be calculated from images of tidal ventilation distribution obtained by electrical impedance tomography (EIT). It has been suggested that the GI index may be useful for individual adjustment of positive end-expiratory pressure (PEEP) and for guidance of ventilator(More)
INTRODUCTION Lung-protective ventilation aims at using low tidal volumes (VT) at optimum positive end-expiratory pressures (PEEP). Optimum PEEP should recruit atelectatic lung regions and avoid tidal recruitment and end-inspiratory overinflation. We examined the effect of VT and PEEP on ventilation distribution, regional respiratory system compliance(More)
BACKGROUND Data regarding radiation exposure related to radial versus femoral arterial access in patients undergoing percutaneous coronary intervention (PCI) remain controversial. This study aims to evaluate patients enrolled in the FERARI study regarding radiation exposure, fluoroscopy time and contrast agent use. METHODS The Femoral Closure versus(More)
