Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Experimental: patients with chronic respiratory diseases

Included patients, aged ≥ 18 years, with chronic respiratory diseases: COPD, bronchial asthma, cystic fibrosis, lymphangioleiomyomatosis, hypersensitivity pneumonitis and other interstitial lung diseases.

Intervention: breath analysis using the Compact PTR-MS proton mass spectrometer by Ionicon (Austria); electrocardiogram (ECG) in one lead with an assessment of the pulse wave using a portable cardiac monitor "CardioQvark"; 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 electrocardiogram (ECG), phonocardiogram (PCG) and pulse waves on the carotid, femoral arteries, as well as on the arteries of four limbs.

Interventions:

Diagnostic Test: Breath analysis using the Compact PTR-MS proton mass spectrometer; Diagnostic Test: Portable cardiac monitor "CardioQvark"; Diagnostic Test: Assessment of arterial stiffness using the VaSera VS-1500N.

Breath test using the Compact PTR-TOF-MS

Intervention Type DIAGNOSTIC_TEST

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).

Portable cardiac monitor "CardioQvark"

Intervention Type DIAGNOSTIC_TEST

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.

Assessment of arterial stiffness using the VaSera VS-1500N

Intervention Type DIAGNOSTIC_TEST

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.
