Insights
Serglycin levels are higher in patients with coronary artery ectasia (CAE). This finding suggests serglycin may be a useful biomarker for detecting CAE.
Area of Science:
- Cardiovascular Research
- Biomarker Discovery
- Inflammation Studies
Background:
- Serglycin is implicated in inflammatory processes.
- The role of serglycin in coronary artery ectasia (CAE) remains unexplored.
Purpose of the Study:
- To investigate the association between serglycin levels and isolated CAE.
- To determine if serglycin can serve as a predictive biomarker for CAE.
Main Methods:
- Plasma serglycin levels were measured in 52 patients with isolated CAE and 35 controls.
- Coronary angiography data, including Markis classification, were analyzed.
- Logistic regression and ROC curve analyses were performed.
Main Results:
- Serglycin and high-sensitivity C-reactive protein were independently associated with CAE presence.
- A serglycin cutoff of 13.5 demonstrated 88.5% sensitivity and 84.8% specificity for predicting isolated CAE.
- No correlation was found between serglycin levels and the Markis classification.
Conclusions:
- Serglycin levels are significantly and independently elevated in patients with CAE.
- Serglycin shows potential as a valuable biomarker for the diagnosis of isolated coronary artery ectasia.
Background:
Serglycin plays an important role in the inflammatory status, but the relationship between coronary artery ectasia (CAE) and serglycin is still unknown.
Aim:
In this study, we aimed to investigate the association of serglycin level with isolated CAE.
Methods:
Fifty-two patients with isolated CAE and 35 individuals with normal coronary angiography were included into the study. The Markis classification and number of ectatic coronary arteries were recorded. Plasma serglycin levels were measured.
Results:
Multivariate logistic regression analysis revealed that serglycin and high-sensitivity C-reactive protein were indepen-dently associated with the presence of CAE. In receiver operating characteristics curve analysis the cut of serglycin level for the prediction of isolated CAE was 13.5, with a sensitivity of 88.5% and a specificity of 84.8%. However, there was no association between serglycin levels and Markis classification.
Conclusions:
Serglycin levels are significantly and independently higher in patients with CAE.
