The study included 120 patients with acute coronary syndrome (ACS), which were divided: in two groups, respectively, with ACS-ST segment elevation (group 1, n = 80), and without this clinical sign (group 2, n = 40). The levels of interleukins (IL)-6, -8, -10, and tumor necrosis factor-α (TNFα) were determined by quantitative ELISA test on the 1st and 10th days of the study. In both groups, the IL-8 and TNFα values on day 1 were similar to the reference level, whereas IL-10 levels were significantly reduced as compared to the standard values. IL-6 level was increased in patients with ACS-ST elevation only in acute phase of ACS, while the patients from group 2 showed normal IL-6 values. On the day 10, TNFα levels in the both groups of patients were significantly increased as compared to the 1st day, whereas IL-6 and IL-10 levels were significantly decreased by the day 10 in both groups of patients. Differential dynamics of IL-8 was observed for these groups of the patients from the day 1 to day 10, i.e., the IL-8 concentration showed a tendency to increase (by 40%) for the group 1 and decrease by 54% in the group 2. In conclusion, the patient grouped by different clinical ACS variants exhibit a similar dynamics of cytokine concentrations, but an increase of IL-8 by the day 10 of the disease was seen only in patients with ACS segment elevation. It may be indicative of different intensity of the inflammatory response.
