Brief Summary

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

It is an observational study in patients with chronic noncommunicable diseases (i.e. cardiovascular diseases, diabetes mellitus, non-alcoholic fatty liver disease, chronic obstructive pulmonary disease and asthma ) and control group with no signs of these conditions. The study has a prospective part planned for 2021 and a retrospective part which includes the patients enrolled between 2018-2020. The aim of the study is to investigate gut microbiota composition, its metabolites, levels of inflammatory and other markers of the disease in prospective groups (arterial hypertension, type 2 diabetes mellitus, chronic obstructive pulmonary disease, asthma, non-alcoholic fatty liver disease and control patients) as well as in retrospective groups (chronic heart failure with preserved and reduced ejection fraction, obstructive atherosclerosis of any vascular bed, arterial hypertension, type 2 diabetes mellitus, chronic obstructive pulmonary disease, asthma, non-alcoholic fatty liver disease, and control patients). Also we are planning to investigate the association between gut microbiota composition and its metabolites, levels of inflammatory and other markers of the disease in retrospective and prospective groups.
