EXPRESS: Serum Talin-1 and Pentraxin-3 Levels as Biomarkers for Vulnerable Plaques in STEMI: Correlation with Syntax and Gensini Scores.

Cardiovascular diseases, especially ischemic heart diseases, are the leading cause of death globally, highlighting the need for improved diagnostic tools for vulnerable plaques. This study aimed to evaluate the potential of soluble Talin-1 (sTalin-1) and Pentraxin-3 (PTX-3) as biomarkers in patients with ST-elevation myocardial infarction (STEMI). Conducted as a single-center observational study, it included 40 STEMI patients and 30 controls with normal coronary arteries. Serum levels of sTalin-1 and PTX-3 were measured using enzyme-linked immunosorbent assays (ELISA), and disease severity was assessed with Syntax and Gensini scores. Results showed that STEMI patients had significantly lower levels of sTalin-1 and higher levels of PTX-3 compared to controls. ROC curve analysis revealed an area under the curve (AUC) of 0.785 for sTalin-1 and 0.702 for PTX-3 in differentiating between STEMI patients and controls. While sTalin-1 demonstrated high specificity but low sensitivity, PTX-3 exhibited moderate sensitivity and specificity. Talin-1 levels negatively correlated with Syntax and Gensini scores, suggesting its role in assessing disease severity. These findings suggest that decreased serum levels of sTalin-1 and increased levels of PTX-3 in STEMI patients could serve as potential biomarkers for identifying vulnerable plaques and assessing disease severity. The study supports the potential use of sTalin-1 and PTX-3 in the diagnostic and prognostic evaluation of acute coronary syndromes.
