Assessment of cardiovascular disorders using echocardiography and arterial stiffness; comparative noninvasive assessment of volatile organic compound (eVOC) exhale breath patterns in patients with different chronic respiratory diseases with age and gender-matched healthy adults in order to identify a disease-specific exhaled eVOCs profiles and markers of respiratory and cardiovascular disorders.
Evaluating of eVOCs profiles by proton mass spectrometry with a time-of-flight (PTR-TOF) in patients with different chronic respiratory diseases is of great interest for assessing the prognosis and development of severe ventilation and cardiovascular disorders.
The aim of our study is to determine the diagnostic significance of PTR-TOF analysis in patients with chronic respiratory diseases and to identify specific eVOC markers of a severe ventilation and cardiovascular disorders in patients with different chronic respiratory diseases.
