Özet
Aim: Acute coronary syndromes (ACSs) are classified as ST-segment elevated myocardial infarction (STEMI), non-ST-segment elevated myocardial infarction (NSTEMI) and unstable angina pectoris (USAP). Cardiac troponins constitute the cornerstone biomarkers for the laboratory diagnosis of ACS. In this study, we aimed to investigate whether systemic immune-inflammation index (SII) is associated with peak cardiac troponin T (TnT) levels in ACS. Methods: Consecutive patients with ACS whose coronary angiography was performed were included in the present study (n=397). Admission SII was determined as platelet count x neutrophil count/lymphocyte count. Serum levels of cardiac enzymes, including high-sensitivity TnT and creatine kinase-myocardial band (CKMB), were measured at the time of admission and repeated daily during patients’ hospital stay. Results: Patients were categorized as namely STEMI (n=92) and NSTEMI/USAP (n=141). The findings obtained in this study showed that the median of SII levels was higher in STEMI than NSTEMI/USAP at a significant level. Correlation analysis of SII with various clinical and laboratory parameters demonstrated a significant correlation with C-reactive protein, peak CK-MB (r=0.52, p<0.001), peak TnT (r=0.49, p<0.001) and left ventricular ejection fraction (r= -0.48, p<0.001). Multivariate linear regression analysis identified age and log-SII (Beta Coefficient: 1.29, 95% Confidence Interval: 0.93-1.66, p<0.001) as independent predictors of peak TnT levels. Conclusion: SII is an independent predictor of peak TnT levels and significantly correlates with peak CK-MB levels in patients with ACS. SII significantly and inversely correlates with left ventricular systolic functions.
