Insights
Tissue factor (TF) and vascular endothelial growth factor-A (VEGF-A) are elevated in diabetic atherosclerosis patients, indicating potential for early detection of thromboembolic complications. These markers correlate with longer hospital stays and increased risk factors.
Area of Science:
- Cardiovascular Medicine
- Endocrinology
- Biochemistry
Background:
- Atherosclerosis is a leading global cause of death, with diabetes exacerbating thromboembolic complications.
- The precise mechanisms of endothelial damage in diabetic atherosclerosis remain unclear.
- Understanding these mechanisms is crucial for managing cardiovascular risk in diabetic patients.
Purpose of the Study:
- To investigate the role of tissue factor (TF) and vascular endothelial growth factor-A (VEGF-A) in diabetic atherosclerosis.
- To assess TF and VEGF-A as potential indicators of thromboembolic complications in diabetic patients undergoing coronary artery bypass surgery.
- To analyze the correlation between these markers, patient demographics, and postoperative outcomes.
Main Methods:
- A cohort of 100 patients undergoing off-pump coronary artery bypass (OPCAB) were divided into diabetic and non-diabetic groups.
- Preoperative and postoperative levels of TF and VEGF-A were measured.
- Early postoperative outcomes, hospital stay, and carotid intima-media thickness (CT) were analyzed.
Main Results:
- Diabetic patients exhibited statistically significant higher levels of TF and VEGF-A compared to non-diabetics.
- Elevated TF and VEGF-A levels correlated with significantly longer hospital stays in the diabetic group.
- Higher preoperative CT in diabetics was significantly associated with atrial fibrillation (AF).
Conclusions:
- TF and VEGF-A levels may serve as important early indicators for thromboembolic complications in patients with diabetic atherosclerosis.
- These findings highlight the potential of TF and VEGF-A in risk stratification and early detection.
- Further research can elucidate the precise role of these markers in the pathogenesis of diabetic cardiovascular disease.
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.
