Over the last 10 years, many studies were devoted to the role of intestinal microbiota and their metabolites in pathogenesis of cardiovascular diseases.
To estimate the influence of enzymatic activity of microbiota on hemodynamics, arterial stiffness and emotional state of patients with mild-to-moderate risk of cardiovascular complications.
The study included 22 patients with mild-to-moderate risk of cardiovascular complications. In addition to standard examination, patients underwent volumetric sphygmography with analysis of cardio-ankle vascular index, HADS scores and results of hydrogen-methane breath test with lactulose.
CH4-releasing microflora predominated in 7 patients, H2- releasing microflora — in 15 cases. Multivariate regression analysis revealed negative correlation between systolic blood pressure and CH4 level (r=–0.530; p=0.008). CH4 AUC was an age-independent predictor of higher systolic blood pressure (β=–0.49; p=0.03). There was a negative correlation between anxiety and H2 (r=–0.44; p=0.05), as well as H2/CH4 ratio (r=–0.53; p=0.02). H2 level was a negative predictor of anxiety independent of age, systolic and diastolic blood pressure, as well as heart rate (β=–0.64; p<0.01). There was a negative correlation between CAVI and exhaled H2 (r=–0.41; p<0.05).
Hydrogen-methane breath test may be advisable for more accurate assessment of risk of cardiovascular complications and their personalized prevention.
