Abstract

Vascular endothelial growth factor (VEGF) is a regulator of vascular formation in physiological and pathological conditions. The aim of our study was to evaluate the value of VEGF as a surrogate marker of myocardial injury in acute ischemic conditions.

MATERIALS AND METHODS:

In 104 consecutive patients with acute coronary syndrome (ACS) with and without ST segment elevation (STEMI and NSTEMI) the plasma and serum human VEGF (hVEGF) concentration was measured two times i.e. immediately after admission due to ACS and 24h later. According to ECG findings and coronary angiography results, patients were divided into three groups. Group A represented major myocardial injury due to ST-segment elevation in precordial leads and/or in I and aVL leads and with left anterior descending (LAD) artery responsible for STEMI symptoms or additionally with significant atherosclerotic lesions (lumen vessel narrowed>50%) in other than LAD coronary arteries. Group B (medium myocardial injury) consisted of patients with ST-segment elevation in II, III and aVF leads and/or ST-segment depression in V2-V3 leads with one-vessel disease and the culprit artery was not LAD. Group C included patients with changes in ECG other than ST-segment elevation independently of the site of atherosclerotic lesions in coronary arteries.

RESULTS:

In all 104 patients with ACS the highest values of serum hVEGF were observed in second measurement (357.9 ± 346 pg/ml, p<0.01). Although in the first measurement, plasma and serum hVEGF concentration did not differentiate groups, the difference between deltas for serum hVEGF was observed (p<0.05). Increased number of neutrophils in the first measurement increased the OR of the high serum hVEGF concentration in the first measurement (OR=1.155; 95%CI: 1.011; 1.32) (p<0.05). The number of neutrophils in the second measurement also revealed significant relationship with high serum hVEGF in the first assessment (OR=1.318, 95%CI: 1.097; 1.583) (p<0.01). Increased values of triglycerides (exceeding the upper limit) were connected with decreased OR of high serum hVEGF concentrations in the first measurement (OR=0.152, 95%CI: 0.033; 0.695, p<0.05).

CONCLUSIONS:

In acute coronary syndrome, serum VEGF concentrations are elevated and can serve as a surrogate marker of myocardial injury. The elevated number of neutrophils increases odds ratio of high VEGF concentrations in ACS. In patients with high concentrations of triglycerides, odds ratio of low level of hVEGF is expected.
