Tissue Factor and Vascular Endothelial Growth Factor in Detecting Thromboembolic Complications in Diabetic Atherosclerotic Patients.

Abstract

Background: Atherosclerosis, which is one of the leading causes of death all over the world, can create major or minor thromboembolic complications with the exponentially increasing diabetic status. Despite all the studies, the mechanism by which endothelial damage in atherosclerosis is triggered in diabetic setting is still not fully understood.

Methods: In this study, tissue factor (TF), which is thought to act together in the formation of vasular endothelial growth factor (VEGF-A) and coagulopathy in diabetic atherosclerotic patients, may be an important indicator in this regard, a total of 100 cases who were undergone off-pump coronary artery bypass (OPCAB) which were at same risk group examined by dividing into diabetic status. Early postoperative process and biochemical parameters analyzed in terms of TF and VEGF-A levels measured before and after the operation.

Results: TF and VEGF-A expression of the T1DM group were statistically high compared to non-diabetics. Significantly longer hospital stays with changes in TF and VEGF-A were found in patients in the diabetic group compared to pre- and postoperatively, respectively; TF (95% CI: 0.879-0.992; p = 0.025), VEGF-A (95% CI: 0.964-0.991; p = 0.001) and hospital stay (95% CI: 1.96-7.49; p = 0.0001). Preoperatively measured carotid intima-media thickness (CT) was higher in diabetics and was significantly associated with atrial fibrillation (AF), (r = 0.873). Surgical team and protocols were same and OPCAB procedures were routinely applied to all patients in our clinic. No minor or major events were observed in any of the cases.

Conclusion: TF and VEGF-A values in patients with diabetic atherosclerosis may be important in the early detection of thromboembolic complications.
