Purpose: To assess the suppression of tumorogenicity 2 (ST2) and copeptin significance for risk stratification of patient (pts) with acute decompensated heart failure (ADHF) during long-term follow-up compared with traditional risk factors.

Methods: We included in a prospective study 159 pts with ADHF. Blood samples to determine copeptin, sST2, NT-proBNP and hsTnT concentration were collected at admission and at discharge from the hospital.

Purpose: to study prognostic value of various biomarkers and their combinations in patients who survived decompensation of chronic heart failure.

Materials And Methods: Patients (n=159) who were hospitalized with diagnosis of heart failure (HF) decompensation were included in a prospective single-center study. Examination on admission and the day of hospital discharge, included measurement of concentrations of N-terminal pro-brain natriuretic peptide (NT-proBNP), high-sensitivity troponin T (hsTnT), copeptin, soluble suppression of tumorigenicity 2 (sST2), kopetin, neutrophil gelatinase-associated lipocalin (NGAL), and galectin-3.

Aim: Monitoring of concentrations of modern biomarkers to evaluate the efficacy of long‑term treatment of patients after acute decompensated HF (ADHF).

Materials And Methods: The study included 100 patients with severe decompensated FC II-IV CHF and LV EF <40 % due to IHD, DCMP or AH. At discharge from the hospital, patients were divided into groups of low (NT‑proBNP<1400 pg / ml) (control, n=30) and high (NT‑proBNP≥1400 pg / ml) risk (n=70).

In this paper, we study scalar multivariate non-stationary subdivision schemes with integer dilation matrix  and present a unifying, general approach for checking their convergence and for determining their Hölder regularity (latter in the case [Formula: see text]). The combination of the concepts of asymptotic similarity and approximate sum rules allows us to link stationary and non-stationary settings and to employ recent advances in methods for exact computation of the joint spectral radius. As an application, we prove a recent conjecture by Dyn et al.
