Abstract:

Background: Signal peptide-CUB (complement C1r/C1s, Uegf, and Bmp1)-EGF (epidermal growth factor)- like domain- containing protein 1(SCUBE-1) is a surface cell protein studied as a biomarker in thrombosis and ischemia conditions and secreted at currently studied early embryogenesis. The aim of this study is to investigate the relationship between left ventricular functions and pericardial / serum SCUBE-1 values of patients who underwent coronary artery bypass surgery. Material and Methods: Forty patients who underwent cardiopulmonary bypass graft surgery were included in the study. Detailed echocardiographic findings of the patients were made before the operation. Left ventricular dysfunction markers were determined according to left ventricular fracshortening. SCUBE-1 levels were studied with ELISA kits in blood plasma and pericardial fluid samples. SCUBE-1 levels were statistically compared between the determined groups. Results: Statistical differences were observed in LVDs, IVSd, Neutrophil, RBC, CK-MB, Troponin-I and WBC values in low and high FS groups (p <0.05). SCUBE-1 plasma levels did not differ statistically between the FS groups (p> 0.05). The same situation was similar for pericardial fluid levels (p> 0.05). Correlation was seen between SCUBE-1 plasma levels and SCUBE-1 pericardial levels (p <0.05). There was no significant correlation between echocardiographic findings and SCUBE-1 levels (p> 0.05). Conclusion: These results showed us that SCUBE-1 plasma and the pericardial fluid levels had no effect on the left ventricular dysfunction. SCUBE-1 is not one of the currently identified markers of cardiac dysfunction. Future studies will further increase our knowledge on this subject.
