Study summary

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.

Read the detailed description

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 population

The study population consists of all males and females over 18 years old in the community according to inclusion, non-inclusion, and exclusion criteria.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Written to participate in the study;
  2. Age 18 and over;
  3. Clinical diagnosis of one of chronic respiratory diseases (, bronchial asthma, cystic fibrosis, lymphangioleiomyomatosis, pneumonitis or other interstitial lung disease).

Exclusion criteria

Exclusion Criteria:

  1. Unable to sign ;
  2. Respiratory disease (for controls);
  3. Mental illness (severe dementia, schizophrenia, severe depression, manic-depressive psychosis);
  4. Acute coronary syndrome, acute cerebrovascular accident, pulmonary embolism within the last 3 months;
  5. Oncology;
  6. Previous lung transplantation (for patients with respiratory diseases);
  7. Diseases and conditions that can change the picture and complicate the analysis of the ECG (conduction disturbance, pacemaker);
  8. Inability to use a heart monitor (congenital developmental anomalies, traumatic amputation of the upper limbs, essential tremor, Parkinson's disease);
  9. Pregnancy.
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

Interventions

  • Diagnostic testBreath 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).

  • Diagnostic testPortable 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.

  • Diagnostic testAssessment 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.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 30, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
