Background: The role of thrombus aspiration plus primary percutaneous coronary intervention in ST-segment elevation myocardial infarction remains controversial. Methods: We performed a meta-analysis of 25 randomised controlled trials in which 21,740 ST-segment elevation myocardial infarction patients were randomly assigned to thrombus aspiration plus primary percutaneous coronary intervention or primary percutaneous coronary intervention. Study endpoints were: death, myocardial infarction, stent thrombosis and stroke. Results: On pooled analysis, the risk of death (4.3% vs. 4.8%, odds ratio (OR) 0.90, 95% confidence interval (CI) 0.79–1.03; P=0.123), myocardial infarction (2.4% vs. 2.5%, OR 0.95, 95% CI 0.80–1.13; P=0.57) and stent thrombosis (1.3% vs. 1.6%, OR 0.80, 95% CI 0.63–1.01; P=0.066) was similar between thrombus aspiration plus primary percutaneous coronary intervention and primary percutaneous coronary intervention. The risk of stroke was higher in the thrombus aspiration plus primary percutaneous coronary intervention than the primary percutaneous coronary intervention group (0.84% vs. 0.59%, OR 1.401, 95% CI 1.004–1.954; P=0.047). However, on sensitivity analysis after removing the TOTAL trial, thrombus aspiration plus primary percutaneous coronary intervention was not associated with an increased risk of stroke (OR 1.01, 95% CI 0.58–1.78). The weak association between thrombus aspiration and stroke was also confirmed by the fact that the lower bound of the 95% CI was slightly below unity after removing either the study by Kaltoft or the ITTI trial. There was no interaction between the main study results and follow-up, evidence of coronary thrombus, or study sample size. Conclusions: In patients with ST-segment elevation myocardial infarction, thrombus aspiration plus primary percutaneous coronary intervention does not reduce the risk of death, myocardial infarction or stent thrombosis. Thrombus aspiration plus primary percutaneous coronary intervention is associated with an increased risk of stroke; however, this latter finding appears weak.

<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>

Introduction. Stent thrombosis (ST) in clinical practice can be classified according to time of onset as early (0?30 days after stent implantation), which is further divided into acute (< 24 hours) and subacute (1?30 days), late (> 30 days) and very late (> 12 months). Myocardial reinfaction due to very late ST in a patient receiving antithrombotic therapy is very rare, and potentially fatal. The procedure alone and related mechanical factors seem to be associated with acute/subacute ST. On the other hand, in-stent neoathero-sclerosis, inflammation, premature cessation of antiplatelet therapy, as well as stent fracture, stent malapposition, un-covered stent struts may play role in late/very late ST. Some findings implicate that the etiology of very late ST of bare-metal stent (BMS) is quite different from those following drug-eluting stent (DES) implantation. Case report. We presented a 56-year old male with acute inferoposterior ST segment elevation myocardial infarction (STEMI) related to very late stent thrombosis, 9 years after BMS implantation, despite antithrombotic therapy. Thrombus aspiration was successfully performed followed by percutaneous coronary intervention (PCI) with implantation of DES into the pre-viously implanted two stents to solve the in-stent restenosis. Conclusion. Very late stent thrombosis, although fortu-nately very rare, not completely understood, might cause myocardial reinfaction, but could be successfully treated with thrombus aspiration followed by primary PCI. Very late ST in the presented patient might be connected with neointimal plaque rupture, followed by thrombotic events.

Background. Individual randomized trials have suggested that everolimus-eluting stents may have improved clinical outcomes compared to paclitaxel-eluting stents, but individual trials are underpowered to examine outcomes such as mortality and very late stent thrombosis. Methods. Medline, Cochrane, and conference proceedings were searched for randomized trials comparing everolimus versus paclitaxel-eluting stents for percutaneous coronary intervention. Results. 6792 patients were included from 4 randomized controlled trials. Stent thrombosis was reduced with everolimus stents versus paclitaxel stents (0.7% versus 2.3%; OR: 0.32; CI: 0.20–0.51; P<0.00001). The reductions in stent thrombosis were observed in (i) early stent thrombosis (within 30 days) (0.2% versus 0.9%; OR: 0.24; P=0.0005), (ii) late (day 31–365) (0.2% versus 0.6%; OR: 0.32; P=0.01), and (iii) very late stent thrombosis (>365 days) (0.2% versus 0.8%; OR: 0.34; P=0.009). The rates of cardiovascular mortality were 1.2% in everolimus group and 1.6% in paclitaxel group (OR: 0.85; P=0.43). Patients receiving everolimus-eluting stents had significantly lower myocardial infarction events and target vessel revascularization as compared to paclitaxel-eluting stents. Interpretation. Everolimus compared to paclitaxel-eluting stents reduced the incidence of early, late, and very late stent thrombosis as well as target vessel revascularization.
