Informativeness of cytokine profile in predicting complications in patients with myocardial infarction on background of chronic obstructive pulmonary disease

Objective. To determine the information content of the cytokine profile (IL-1β, IL-2 and IL-6) in predicting complications in patients with myocardial infarction (MI) against the background of chronic obstructive pulmonary disease (COPD). Materials and methods. In 85 people were examined: 28 patients with myocardial infarction, 37 patients with comorbid pathology (MI + COPD) and 20 somatically healthy volunteers as a control group. Determination of IL-1β, IL-2 and IL-6 levels was basing on enzyme immunoassay. Results. When assessing the cytokine profile in patients with MI and MI against the background of COPD, the most pronounced differences between groups of patients were observed in the levels of IL-6. Analyzing the association of the level of IL-6 with the presence of early complications of MI, it was found that the level of IL-6 in patients with complicated MI was significantly higher than in patients with uncomplicated course. The highest level of IL-6 was recorded in the subgroup of patients with complicated myocardial infarction during COPD. Studying the levels of IL-6 depending on the type of complications of myocardial infarction showed that the highest values of IL-6 were recorded in the group of comorbid patients with cardiogenic shock and pulmonary edema. Conclusion. When determining the cytokine status in patients with myocardial infarction on the background of COPD, the level of IL-6 should be considered as the main indicator. This cytokine can be considered a marker of left ventricular that developed in the acute period in patients with myocardial infarction on the background of COPD.
