RESUMEN
OBJECTIVE: The aim: To study the relationship between the concentration of copeptin, NT-proBNP, ST2 and indicators of myocardial remodeling, the dynamics of these indicators in order to predict the occurrence of decompensated heart failure (HF) in patients with acute myocardial infarction (AMI). PATIENTS AND METHODS: Materials and methods: The study is based on the results of the examination of 160 patients with MI, including 120 patients with decompensated CHF II A-B stage according to Vasylenko-Strazhesko classification of (FC) III-IV (according to NYHA) and 40 patients with MI without signs of decompensated CHF, as well as 20 medically healthy individuals. The level of copeptin, NT-proBNP, ST2 were determined. RESULTS: Results: In patients with signs of decompensated HF there were significantly higher levels of NT-proBNP in the blood serum that amounted to (950.38±3.15) pg/ml, in patients without decompensated HF after MI (580.15±3.03) pg/ml compared to healthy individuals (111.20±3.47) pg/ml (p<0.05). The mean value of copeptin concentration in patients with decompensated CHF was recorded (18.11±0.12) pg/ml, compared to (12.03±0.14) pg/ml in patients with MI without signs of CHF decompensation. CONCLUSION: Conclusions: The most significant for clinical and prognostic assessment of the post-infarction period complicated by decompensated HF is the response of the patient's body to dosed physical exertion and the levels of NT-prpBNP, copeptin and ST2.
