A.; Malinovskaya, L. K.; Chomakhidze, P. Sh.; Trushina, O. V.; Shaltaeva, Y. R.; Belyakov, V. V.; Golovin, A. V.; Pershenkov, V. S.; Шалтаева, Юлия Ринатовна; Беляков, Владимир Васильевич© 2019 Media Sphera Publishing Group. All rights reserved.Exhaled breath analysis is a novel tool for diagnostics of different diseases. Taking into account the secretory function of the lungs, the composition of exhaled breath is different in physiological and pathological conditions. In this review we consider of some substances which content vary in cardiovascular diseases – pentane, isoprene, carbon monoxide and trimethylamine. Modern technologies allow to move the analysis of exhaled breath from research laboratories into clinical practice. Thus, a new tool for real time of screening various cardiovascular diseases has appeared in the arsenal of physicians.
- ПубликацияТолько метаданныеExhaled breath analysis in diagnosis of chronic heart failure with reduced left ventricular ejection fraction(2019) Bykova, A. A.; Malinovskaya, L. K.; Trushina, O. V.; Chomakhidze, P. S.; Shaltaeva, Y. R.; Шалтаева, Юлия Ринатовна© 2019, Media Sfera. All rights reserved.Objective — searching for chronic heart failure (CHF) biomarkers in patients with heart failure and reduced LVEF through exhaled breath analysis by proton mass spectrometry. Material and methods. The study included 42 patients with CHF and reduced LVEF (HF-REF) and 24 patients without CHF in the control group for the period from October 2014 to April 2016. Exhaled breath samples were collected in 1L Tedlar bags (USA). Exhaled breath samples were analyzed using PTR-MS (Compact PTR-MS, «Ionicon», Austria) within 24 hours after sampling. Results. Men significantly prevailed (90.5%) in HF group compared with the control group (59.3%; p<0.0001). Previous myocardial infarction was more common in patients with CHF (p=0.021). Exhaled breath composition in patients with CHF along 36 channels of mass spectrometer differs from that in the control group. Most of these substances (n=23) were in trace amounts in exhaled breath (<1 · 10–9). Pathophysiological mechanisms of formation are known only for acetone (985 · 10–9 vs. 330 · 10–9 in patients with HF and in the control group, respectively; p<0.0001). There were correlations of exhaled acetone with LVEF, mean pulmonary artery pressure, NT-proBNP, urea, uric acid and total bilirubin. It was also found that exhaled acetone concentrations are various in patients with different NYHA functional class of CHF and higher in patients with NYHA class IV compared with patients with NYHA class II (p=0.006). ROC-analysis was performed to estimate diagnostic accuracy of exhaled acetone for diagnosis of HF-REF. AUC was 0.811 (95% CI 0.707—0.915; p<0.0001). No correlation of exhaled acetone and blood glucose was revealed. Conclusion. Exhaled breath analysis may be used as a new non-invasive screening test for HF-REF. Exhaled acetone is characterized by the greatest diagnostic value.
- ПубликацияТолько метаданныеExhaled breath mass spectrometry in heart failure diagnostics(2019) Malinovskaya, L.; Bykova, A.; Chomakhidze, P.; Kopylov, F.; Patrikeev, L.; Vasilev, V.; Belyakov, V.; Golovin, A.; Pershenkov, V.; Malkin, E.; Gromov, E.; Ivanov, I.; Matusko, M.; Shaltaeva, Y.; Беляков, Владимир Васильевич; Малкин, Евгений Константинович; Иванов, Игорь Александрович; Шалтаева, Юлия РинатовнаCopyright © 2019 Inderscience Enterprises Ltd.Heart failure (HF) affects almost all organs and systems, including general and local pulmonary metabolism, thus effecting on volatile organic compounds concentration in expired air. The aim of the present study is to evaluate the value of expired air analysis (proton mass spectrometry, PTR-MS) for the diagnosis of HF. The study population included 19 patients with stable chronic New York Heart Association (NYHA) functional classification class 2-3 and 16 sex and age matched controls without signs and symptoms of HF. Expired air analysis could provide facilities of early diagnosis and monitoring in HF patients. Most patients had ischemic aetiology of HF, and 31% of them had NYHA class 2 and 69% NYHA class 3 symptoms. Fasted expired air collected by special Tedlar bags was analysed by Compact PTR-MS. The composition of expired air was analysed by deviation of the content of certain substances against their concentration in neutral air. Analysis of samples from patients reveals 24 substances that differ in concentration from the neutral air. Six of them differ significantly in patients with and without HF. Namely, the concentrations of acetone, formaldehyde, propylene, acetic acid, xylene and benzoates were significantly elevated in HF patients (p > 0.05).
- ПубликацияТолько метаданныеIon Mobility Spectrometry of Imidazole and Possibilities of Its Determination(2021) Aleksandrova, D. A.; Melamed, T. B.; Baberkina, E. P.; Kovalenko, A. E.; Shaltaeva, Y. R.; Belyakov, V. V.; Шалтаева, Юлия Ринатовна; Беляков, Владимир Васильевич© 2021, Pleiades Publishing, Ltd.Abstract: The drift time and ion mobility of imidazole are determined and a procedure for the mathematical processing of spectra is developed. The specific features of changes in the ion mobility spectrum during measurements at a particular time are studied. The structures of the generated ions are proposed based on the interpretation of spectral signals, and the enthalpies of formation of the generated ions are estimated. The characteristic signal of the imidazole ion protonated at the nitrogen atom of the pyridine type was revealed. The limit of detection for imidazole in recording with the Kerber detector was found to be 0.3 ng.
