<p><strong>Aim.</strong> To evaluate in-hospital outcomes of direct stenting compared with stenting after predilation in patients with ST-elevation myocardial infarction and hyperglycemia at admission.<br /><strong></strong></p><p><strong>Methods.</strong> Data were collected from hospital database, which includes information about all patients (n = 1 469) with ST-elevation myocardial infarction admitted to the coronary care unit and submitted to percutaneous coronary intervention. Plasma glucose was measured at hospital admission. Hyperglycemia was defined as plasma glucose of 7.77 mmol/L (140 mg/dL), regardless of the diabetic status. A total of 695 (46.3%) patients with hyperglycemia at admission were included in the analysis. Direct stenting (DS) was performed in 358 (51.5%) patients and 337 (48.5%) patients received stenting non-direct stenting. Among non-direct stenting group 292 (86.6%) patients received stenting after predilation, 19 (5.6%) patients received manual thrombus aspiration and 26 (7.7%) patients received stenting after combination of predilation and thrombus aspiration. The clinical and angiographic characteristics, in-hospital outcomes, as well as predictors of angiographic no-reflow were analysed. The composite of in-hospital death, myocardial infarction, and stent thrombosis were defined as major adverse cardiac events (MACE). </p><p><strong>Results.</strong> The rate of angiographic success was higher in DS group (96.1% vs. 89%, р&lt;0,001). There were no difference in rates of stent thrombosis (1.1% vs. 0.9%, р = 0.764), repeat myocardial infarction (1.7% vs. 1.2%, р = 0,588), and access site complications (3.4% vs. 5.4%, р = 0.194) between groups. The rates death (3.9% vs. 9.5%, р = 0.003), MACE (5.3 vs. 11.3, р = 0.004), and no-reflow (2.2% vs. 11%, р&lt;0.001) were significantly lower in the direct stenting group. Following propensity score matching, each group contained 160 patients. The rate of no-reflow (3.1% vs. 10.0%, р = 0.013) remain significantly lower in the DS group. There were no differences in rates of death (4.4% vs. 6.9%, p = 0.454), MACE (6.3% vs. 8.1%, p = 0.664), stent thrombosis (1.9% vs. 0.6%, p = 0.625), and repeat myocardial infarction (0.6% vs. 0.6%, р = 1,00) between groups. </p><p><strong>Conclusion.</strong> Direct stenting in patients with ST-elevation myocardial infarction and hyperglycemia is a safe and feasible technique. Direct stenting in patients with hyperglycemia undergoing percutaneous coronary intervention for ST-elevation myocardial infarction was characterised with decrease in no-reflow rate.</p>

Objective: In this study, we aimed to determine the predictive value of the CHA2DS2VASc score for acute stent thrombosis in patients with an ST elevation myocardial infarction treated with a primary percutaneous coronary intervention (pPCI). Methods: This was a retrospective study conducted among 3,460 consecutive patients with STEMI who underwent a pPCI. The stent thrombosis was considered a definite or confirmed event in the presence of symptoms suggestive of acute coronary syndrome and angiographic confirmation of stent thrombosis based on the diagnostic guidelines of the Academic Research Consortium. The stent thrombosis was classified as acute if it developed within 24 h. Results: The mean CHA2DS2VASc score was 3.29 ± 1.73 in the stent thrombosis group, whereas it was 2.06 ± 1.14 in the control group (p < 0.001). In multivariable logistic regression analysis, CHA2DS2VASc scores ≥ 4 were independently associat ed with acute stent thrombosis (OR = 1.64; 95% CI 1.54–1.71, p < 0.001). In a receiver operating characteristic curve ana­lysis, the best cut-off value for the CHA2DS2VASc score was ≥4, with 60% sensitivity and 73% specificity. Of note, pa tients with a CHA2DS2VASc score of 4 had a 4.3 times higher risk of acute stent thrombosis compared to those with a CHA2DS2VASc score of 1. Conclusions: The CHA2DS2VASc score may be a significant independent predictor of acute stent thrombosis in patients with STEMI treated with a pPCI. Therefore, the CHA2DS2VASc score may be used to assess the risk of acute stent thrombosis in patients with STEMI following a pPCI.

Aim: This study sought to investigate the predictive value of estimated whole blood viscosity (WBV) for stent thrombosis (ST) in ST-elevation myocardial infarction (STEMI) patients who underwent percutaneous coronary intervention. Materials & methods: A total of 1720 STEMI patients treated with primary percutaneous coronary intervention were followed up for median 36.0 months. WBV was calculated according to the Simone’s formula. Results: During follow-up period, 119 patients were diagnosed as ‘definite’ ST. The rate of ST was significantly higher in the high WBV group. In multivariate analysis, adjusted for other factors, higher WBV significantly increased risk of ST at both shear rates. Conclusion: Being an easily accessible and costless parameter, WBV seems to be an emerging predictor of ST in patients with STEMI.
