Abstract
Вackground. Heart failure (HF) is one of the main causes of morbidity and mortality worldwide. Since it is important to diagnose CH early and quickly, at the outpatient appointment, there is a need to create and introduce into practice a portable highly sensitive method for the determination of BNP, NT-proBNP.
Purpose of the study. To determine the possibility of using reagents for semi-quantitative determination of N-terminal brain natriuretic peptide antigen for early detection of heart failure.
Methods of statistical analysis. Microsoft Office Excel 2019 program was used.
Patient Characterization and Research Methods. An open cross-sectional non-randomized cohort study included 50 patients (mean age 63.5 years) who applied on an outpatient basis for consultation to a cardiologist. In addition to standard clinical, biochemical and instrumental examinations, the concentration of N-terminal brain natriuretic peptide (NT-proBNP) was determined by quantitative and semi-quantitative immunochromatographic method (LLC NPO "BioTest", Novosibirsk). The diagnosis of chronic heart failure (CHF) was established in accordance with national and European recommendations.
Methods of statistical analysis. Microsoft Office Excel 2019 program was used.
Results and conclusion. In the course of the study, it was found that semi-quantitative method is highly sensitive for detection of small NT-proBNP elevations, which is important for early diagnosis of heart failure, including subclinical forms. Semi-quantitative method also allows to distinguish a group of patients with high NT-proBNP values. The relationship of NT-proBNP level with the course and prognosis of CHF requires further study.
