Aim. Comparative assessment of laboratory and instrumental parameters of patients with heart failure (HF) after myocardial infarction at admission and discharge from the hospital to determine the long-term mortality risk.Material and methods. The clinical outcomes of 117 patients with stage II-III (Strazhesko-Vasilenko Classification) heart failure (64 men and 53 women) were studied. All patients admitted to the hospital underwent laboratory and instrumental examination. The average follow-up for patients after discharge from the hospital was 3 years (12 to 44 months). The long-term mortality risks of HF patients were compared according to the examination data upon admission and discharge from the hospital.Results. The long-term mortality risk factors of HF patients at admission are the levels of pro-brain natriuretic peptide (proBNP) (risk 1,08, p=0,001), D-dimer (risk 1,062, p=0,018), urea (risk 1,048, p=0,016), creatinine (risk 1,006, p=0,016), alanine transaminase (risk 1,002, p=0,009). The long-term mortality risk factors of HF patients at discharge are urea (risk 1,141, p=0,001), N-terminal proBNP (risk 1,101, p=0,002), and the number of neutrophils (risk 1,064, p=0,002).Conclusion. There is a difference in risk factors for long-term mortality risk of HF patients at admission and discharge from the hospital.
