A total of 148 patients with acute coronary syndrome, unstable angina and acute myocardial infarction (AMI), and 57 practically healthy individualswere examined. The concentration of vascular endothelial growth factor (VEGF) in the serum of patients with AMI was studied in the dynamics of treatment. Upon admission to hospital, inall groupsof the patients therewereno significant differenceswith the control values. However, in patients with unstable angina the variance was small. At the same time, a large variation of the values (0 -1848.2 pg/ml) was found inpatients with AMI. In this regard, these patients were divided into 3 groups. 1st group included patients (60.4%) with low levels of VEGF <100 pg/ ml,2nd group (21.9%) - with normal - 100 - 300 pg/ml, 3rd group (17.7%) - withhigh –> 300 pg/ml. When comparing 1st and 3rdgroupswith 2nd group,it is necessary to note later admission to hospital, more frequently recorded previously existing AMI and the presenceof concomitant inflammatory diseasesin3rdgroup. Dynamic monitoring of the AMI course during first 7 days of the disease revealed the increase of VEGF in 1st and 2nd groups and the absence of changes in 3rd group. Thus, an increase of VEGF in patients with low and “normal” content of this factor likely indicates its compensatory role for AMI. The absence of this factorgrowth in patients with its initially very high value together with a combination of risk factors may reflects the maximum stress of the compensatory mechanisms and a suboptimalcourse, from a physiological point of view,of AMI hospital period.
