Aim. To analyze the pregnancy associated protein A and insulin-like growth factor 1 levels in blood plasma of patients with acute coronary syndrome and determination of gender- and age-related features of proteins values.

Methods. The study included 71 patients with acute coronary syndrome, including 47 men and 24 women. The control group consisted of 20 healthy people matched for age and sex, the comparison group - 40 patients with a diagnosis of «hypertension» and «chronic ischemic heart disease». Pregnancy-associated plasma protein A, and insulin-like growth factor 1 determination was performed.

Results. The concentration of a pregnancy-associated plasma protein A was higher in acute coronary syndrome compared with control and comparison groups. The content of insulin-like growth factor-1 in myocardial infarction is lower than in the comparison group. An increase in concentration of insulin-like growth factor 1 in unstable angina has no significant differences from the control and comparison groups. The highest levels of insulin-like growth factor-1 are registered in the comparison group, the lowest ones - in the subgroup with a fatal outcome. A statistically significant difference between the parameters in men and women was demonstrated in the groups with acute coronary syndrome and unstable angina for insulin-like growth factor 1, in the group with myocardial infarction - for a pregnancy-associated plasma protein A. Insulin-like growth factor 1 levels inversely correlated with age, which confirms reparative role of the protein.

Conclusion. Pregnancy-associated plasma protein A and insulin-like growth factor 1 are new highly sensitive biochemical markers of vascular inflammation and injury, their levels can be used to predict the instability of atherosclerotic plaque in acute coronary pathology and assessing the disease prognosis.
