The aim – to research associations between vascular endothelial growth factor-A (VEGF-A) level and left ventricular remodeling after ST elevation myocardial infarction (MI).
Material and methods. 62 patients with MI, 51 (82.3 %) male and 11 (17.7 %) female at average age 58.63±8.90 years were enrolled into the study. VEGF-A level was determined on the 7th day of MI by enzyme-linked immunoassay. Anxiety level was assessed by Taylor questionnaire during the period of 10–14 days before MI. After 6-month observation 47 patients were assessed.
Results. In patients with MI in comparison with the control group significant rise of serum VEGF-A level was observed, showing positive correlation with creatine kinase level. The level of VEGF-A below median 160 pg/ml in comparison with its level above the median 160 pg/ml was associated with higher frequency of MI in men (Р=0.023), anxiety before MI (Р=0.019), end diastolic diameter (EDD), end systolic diameter (ESD), end diastolic volume (EDV) increase in acute phase, EDD, ESD, EDV, left ventricular myocardial mass, Е/А, lower exercise tolerance after 6-month observation. This processes indicates unfavorable role of low VEGF-A levels and protective – of high VEG-A levels for intracardiac hemodynamic after myocardial infarction. The level of VEGF-A ≤ 201.86 pg/ml with sensitivity 57.9 % and specificity 85.7 % (AUC 0.711; 95 % CI 0.513–0.908; Р=0.036) have prognostic significance for adverse remodeling development.
Conclusions. VEGF-A level – important indicator to estimate the extent of myocardial injury and pathologic remodeling development.
