Acute stent thrombosis (AST) is associated with increased morbidity and mortality. The main aim of this study was to evaluate the prognostic value of the systemic immune-inflammation index (SII) and C-reactive protein (CRP) to albumin ratio (CAR) in predicting AST and high SYNTAX score in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). The criteria of the Academic Research Consortium were used to determine definite stent thrombosis. A total of 2077 consecutive patients with ACS undergoing PCI were retrospectively enrolled. Platelet, white blood cell and neutrophil counts, as well as SII, CRP, CAR, and peak cardiac troponin I (cTnI) values were significantly higher, whereas the lymphocyte count and albumin values were significantly lower in the AST (+) group compared with the AST (−) group (P < .05). SYNTAX score showed significant positive correlations with SII (r = .429, P < .001) and CRP (r = .402, P < .001). Multivariate logistic regression analysis showed that SII and CAR, as well as age, diabetes mellitus, stent length, and peak cTnI are independent predictors of AST and high SYNTAX score. In conclusion, the SII and CAR are simple, relatively cheap, and reliable inflammatory biomarkers that can predict AST and high SYNTAX scores in ACS.

Objective: The literature concerning the association between coronary slow flow (CSF) and anxiety and depression is controversial. Furthermore; there is no existing data in the literature on the potential association between CSF and adverse childhood experiences or alexithymia. Methods: The participants underwent coronary angiography through femoral access. Coronary artery blood flow rate was evaluated quantitatively for each coronary artery according to the Thrombolysis in Myocardial Infarction frame count (TFC) method. CSF was diagnosed as a corrected TFC value >27 in at least one coronary artery during the imaging. Symptoms of anxiety and depression were assessed through the Hospital Anxiety and Depression Scale (HADS). Alexithymia and ACE were evaluated by the Twenty-item Toronto Alexithymia Scale (TAS-20) and the Childhood Trauma Questionnaire (CTQ). Results: The study participants were categorized into two groups: normal coronary flow (n = 58) and CSF (n = 18). Total HADS score; HADS anxiety subscale (HADS-A) score; and HADS depression subscale (HADS-D) score were determined as significant factors associated with CSF in univariate logistic regression analysis. However; the TAS-20 and CTQ scores showed no significant association with CSF. Multivariate regression analysis performed in separate models demonstrated that total HADS score (OR: 1.27; 95 CI%: 1.08–1.50; p = 0.003); HADS-A score (OR: 1.25; 95 CI%: 1.03–1.51; p = 0.019); and HADS-D score (OR: 1.36; 95 CI%: 1.06–1.74; p = 0.014) were independently associated with CSF in multivariate logistic regression analysis. Conclusions: Neither alexithymia nor ACE was associated with CSF. On the other hand; measures of both anxiety and depression assessed through HADS were independently associated with CSF. Future studies should address the major limitations of this study; such as the limited sample size; lack of structured diagnostic interview by a psychiatrist; and the lack of establishment of causality
