Официальное название

Exhaled Breath Proton Mass Spectrometry and Assessment of Endothelial Dysfunction in Patients With Respiratory Diseases

Обзор

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.

Подробное описание

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.

Вмешательства

  • Диагностический тест Breath test using the Compact PTR-TOF-MS
    Breath samples will be analyzed with a proton-transfer reaction mass spectrometer (Compact PTR-MS, Ionicon, Austria) to obtain eVOCs profiles listed as ions at various mass-to-charge ratios (m/z).
  • Диагностический тест Portable cardiac monitor "CardioQvark"
    Record an electrocardiogram (ECG) in one lead with an assessment of the pulse wave using a portable cardiac monitor "CardioQvark" (Russia, LLC "L Card" , RU No. RZN 2019/8124 dated February 15, 2019) once. Devices automatically transfer data to the A\&D Connect app paired with it (link). When transferring data, they are completely protected. The data obtained using the application must be sent to the specialists of the research group in a depersonalized form.
  • Диагностический тест Assessment of arterial stiffness using the VaSera VS-1500N
    Assessment of arterial stiffness using the VaSera VS-1500N Fukuda Denshi device by non-invasive measurement of blood pressure in four limbs with simultaneous recording of ECG, PCG and pulse waves on the carotid, femoral arteries, as well as on the arteries of four limbs.
