Brief Summary

Introduction: Today it is necessary to emphasize that coronary heart disease is often associated with anxiety disorders. Research over the years has shown several and sometimes surprising links between coronary heart disease and mental illness, and has even suggested that both of these phenomena may actually cause each other. However, the exact nature of these links has not yet been clearly established. Methods: The study included 202 patients with coronary artery disease, of whom 42 patients were with stable angina pectoris, they participated as a control group, and 160 patients with unstable angina pectoris, who made up the main group. Among them there are 102 women and 100 men between the ages of 30 and 88. The average age was 63.75 ± 11.37 years. All study participants had blood in the morning on fasting after 8-12 hours of fasting from the cubital vein. Determination of the level of cytokines TNF-α, IL-1β, IL-4 and IL-10 in blood serum by enzyme-linked immunosorbent assay (ELISA). All participants in the study had blood drawn in the morning on fasting after 8-12 hours of fasting from the cubital vein. The level of uric acid was determined on the CYAN Start apparatus using a unified method. When examining patients with unstable angina pectoris were used: hospital anxiety and depression scale \[Kozlova S.N. 2013\]. And also the Spielberger-Khanin scale \[Psychiatry - Hoffman A.G. 2010\], developed by Spielberger Ch.D. and adapted by Yu.L. Khanin. to assess cognitive functions \[Psychiatry - Gofman A.G. 2010\].
