Abstract
Blood flow restoration after primary percutaneous coronary intervention (pPCI) in patients with acute myocardial infarction (AMI) may not always be achieved and could be complicated by the no-reflow phenomenon (NRP). The aim of the current study was to assess the frequency of thrombus aspirations (TAs) and NRPs in patients with AMI and treated with pPCI based on the data collected during a 5-year period in the national ORPKI registry, as well as the frequency of periprocedural strokes and predictors of TA and NRP. This retrospective analysis was performed on prospectively collected data gathered in the Polish National Registry of Percutaneous Coronary Interventions (ORPKI), which covered the period between January 2014 and December 2018, and included 200,991 patients treated due to AMI out of 535,857 patients treated using PCI. Among them, 16,777 patients underwent TA. TA was mainly used in the STEMI subgroup of 14,207 patients (84.8%). The frequency of NRP among AMI patients in the thrombectomy group was 2.75% and in the non-thrombectomy group 0.82%. Predictors of TA and NRP were also assessed using multivariate analysis. The percentage of patients treated with pPCI and with PCI alone increased significantly in all of the three selected groups of patients from 88.7% to 94.3% in the AMI group (p < 0.001), from 82.3% to 90.3% in the STEMI subgroup (p < 0.001), and from 96.3% to 98.2% in the NSTEMI subgroup (p < 0.001) during the analysed period. NRP occurred more often in the thrombectomy group for the NSTEMI (0.58% vs. 3.07%, p < 0.05) and STEMI (1.06% vs. 2.69%, p < 0.05) subgroups. Periprocedural stroke occurred more often in the thrombectomy group in comparison to the non-thrombectomy group with AMI (0.03% vs. 0.01%, p < 0.05) and the NSTEMI (0.16% vs. 0.02%, p < 0.05). In conclusion, the frequency of TA has been experiencing a steady decline in recent years, regardless of AMI type, among patients treated with pPCI.

Abstract
Few data exist on the clinical outcomes of selective aspiration thrombectomy during primary percutaneous coronary intervention (PPCI).This was a nationwide retrospective cohort study. Patients who were diagnosed with ST-elevation myocardial infarction (STEMI) and received primary percutaneous coronary intervention (PCI) from July 2009 to December 2011 were identified from the National Health Insurance Research Database of Taiwan. Propensity score weighting was used to balance the covariates between the 2 study groups. The primary endpoints were all-cause mortality and stroke during hospitalization and at 30 days and 1 year of follow-up. Subgroup analyses were performed based on the hospital and physician volume of primary PCI.A total of 9100 ST-elevation myocardial infarction patients (29.4% of patients receiving aspiration thrombectomy and conventional PPCI vs 70.6% receiving PPCI alone) were identified. The incidence rates of all-cause mortality were comparable between the 2 groups during hospitalization (21.0 vs 27.37/100 person-months; P = .29) and 1-year follow-up (0.81 vs 1.26/100 person-months; P = .85). There were no significant differences in the stroke rates between the 2 groups during hospitalization (1.1 vs 2.34/100 person-months; P = .3) and 1-year follow-up (0.09 vs 0.15/100 person-months; P = .85). For the patients who survived to discharge, the post-discharge 1-year mortality was lower in the aspiration thrombectomy group of patients in whom the procedures were performed by physicians with a high volume of PPCI (hazard ratio: 0.47; 95% confidence interval: 0.24-0.94; P = .03).In this nationwide cohort study, selective aspiration thrombectomy at the operation's discretion had a comparable mortality rate compared with PCI alone and did not increase the risk of stroke. In the patients treated by physicians with a high volume of PPCI, aspiration thrombectomy appeared to have a beneficial effect on post-discharge survival at 1 year.

Abstract
The use of thrombus aspiration (TA) prior to primary percutaneous coronary intervention (PPCI) has undergone a radical change in intervention guidelines. The clinical implications, however, are still under scrutiny. This study investigated the clinical effects and outcome of TA before PPCI in patients with ST-segment elevation myocardial infarction (STEMI). Overall 1027 patients with STEMI were analyzed in this retrospective, propensity score-adjusted, multicenter study. The primary endpoints were in-hospital and long-term mortality. There were 418 patients in the TA group and 609 in the conventional PPCI group. The in-hospital mortality rate was significantly higher in the TA group (8.7 vs. 5.0%; P = 0.03). During long-term follow-up [median follow-up duration 689 days (IQR 405-959)] the mortality rates were similar (TA 14.3%, conventional PPCI 15.0%; P = 0.85). Survival analysis for the complete observation period revealed no significant benefit of TA [hazard ratio (HR) 1.12; 97.5% CI 0.90-0.71; P = 0.63]. There were also no significant differences between the groups in the following secondary endpoints: composite of cardiovascular death and non-fatal reinfarction at discharge (P = 0.39), post-PPCI thrombolysis in myocardial infarction flow-grade-3 (P = 0.14), left ventricular ejection fraction (P = 0.47), and non-fatal reinfarction during follow-up (P = 0.17). Rehospitalization rate (1.82 vs. 10.3%; P < 0.0001) and Canadian Cardiovascular Society (CCS) grading (P = 0.02) during follow-up were significantly lower in the TA group. In our cohort the in-hospital mortality rate was significantly higher for TA patients, but during long-term follow-up the mortality rates did not differ. The incidence of rehospitalization and CCS grading were lower in the TA-treated patients.

Abstract
BACKGROUND Intracoronary nitroprusside and thrombus aspiration have been demonstrated to improve myocardial perfusion during percutaneous coronary interventions (PCI) for ST-segment elevation acute myocardial infarction (STEMI) However, no long-term clinical studies have been performed comparing these approaches. METHODS A single medical center retrospective study was conducted to evaluate the effects of intracoronary nitroprusside administration before slow/no-reflow phenomena versus thrombus aspiration during primary PCI. Forty-three consecutive patients with STEMI were enrolled in the intracoronary nitroprusside treatment group. One hundred twenty-four consecutive STEMI patients who received thrombus aspiration were enrolled; ninety-seven consecutive STEMI patients who did not receive either thrombus aspiration or intracoronary nitroprusside treatment were enrolled and served as control subjects. Patients with cardiogenic shock, who had received platelet glycoprotein IIb/IIIa inhibitor, or intra-aortic balloon pump insertion were excluded. Thrombolysis in Myocardial Infarction (TIMI) flow grade, corrected TIMI frame count and TIMI myocardial perfusion grade (TMPG) were assessed prior to and following PCI by two independent cardiologists blinded to the procedures. The rate of major adverse cardiac events (MACE) at 30 days, 1 year, and 3 years after study enrollment as a composite of recurrent myocardial infarction, target-vessel revascularization, and cardiac death were recorded. RESULTS The control group had a significantly lower pre-PCI TIMI flow (≤ 1; 49.5% vs. 69.8% vs. 77.4%; p = < 0.001) compared with the nitroprusside and thrombus aspiration groups. The thrombus aspiration group had a significantly higher pre-PCI thrombus score (> 4; 98.4% vs. 88.4% vs. 74.3%; p = < 0.001) and post-PCI TMPG (3; 39.5% vs. 16.3% vs. 20.6%; p = 0.001) compared with the nitroprusside and control groups. No significant differences were noted in the post-PCI thrombus score, 30-day, 1-year and 3-year MACE rate, and Kaplan-Meier curve among 3 groups of patients. CONCLUSIONS Although thrombus aspiration provided improved TMPG compared with early administration of intracoronary nitroprusside and neither of both during primary PCI, it did not have a significant impact on 30-day, 1-year and 3-year MACE rate.

Use and impact of thrombectomy in primary percutaneous coronary intervention for acute myocardial infarction with persistent ST-segment elevation: results of the prospective ALKK PCI-registry. Clin Res Cardiol 2015; 104:803-11.

Abstract
BACKGROUND Data about the impact of thrombectomy in primary percutaneous coronary intervention (PCI) are inconsistent. The aim of our study was an evaluation of both the real-world use of thrombectomy and the impact of thrombectomy on outcome in unselected patients treated with primary PCI for ST-elevation myocardial infarction (STEMI). METHODS AND RESULTS We used the data of the prospective ALKK PCI-registry of 35 hospitals from January 2010 to December 2013. A total of 10,755 patients receiving single-vessel primary PCI for acute STEMI were included. In 2176 patients (20.2 %) thrombectomy was performed. There was a wide range of use of thrombectomy in the different ALKK hospitals from 1.1 to 61.7 % (median 18.6 %, quartiles 6.0 and 40.3 %) with a general increase of use over the first years of the study period. In patients with and without thrombectomy there was TIMI 0 flow present before PCI in 6010 patients, TIMI 1 in 1338, TIMI 2 in 2002, and TIMI 3 in 1405. Patients with acute heart failure or cardiogenic shock received significantly more often thrombectomy. Fluoroscopy time (8.1 vs. 7.3 min, p < 0.0001) and dose area product (5373 cGy × cm(2) vs. 4802 cGy × cm(2), p < 0.0001) were significantly higher in patients treated with thrombectomy. The subgroup of patients with TIMI 0 flow before PCI had significantly higher rates of TIMI 3 flow after PCI when treated with thrombectomy (87.1 vs. 84.1 %, p < 0.01), while there was no difference in post-PCI TIMI 3 flow in patients with TIMI 1, 2 or 3 flow before PCI. Rates of major adverse cardiac and cerebrovascular events were similar in both groups in general and in all subgroups of TIMI flow. CONCLUSIONS The use of thrombectomy in patients with STEMI is heterogenous between hospitals. Overall, there was no impact of thrombectomy on TIMI 3 patency or mortality after PCI. In the subgroup of STEMI patients with TIMI 0 flow before PCI individualized thrombectomy had a positive impact on restoration of normal blood flow.

Abstract
BACKGROUND In STEMI patients treated by primary PCI, damage of the microvascular circulation caused by distal embolization of thrombotic material affects the quality of myocardial reperfusion. Important controversies remain concerning the usefulness of the manual thrombectomy to improve myocardial perfusion. The aim of this study is to evaluate the impact of manual thrombectomy on ST resolution as a surrogate of reperfusion extent. METHODS Two hundred and thirty-nine consecutive STEMI patients with an <12 hours onset of symptoms, were enrolled in an observational registry. Patients were divided into two cohorts according to the reperfusion strategy: manual thrombectomy before primary PCI (n=102) or conventional-PCI (n=137). The primary endpoint was the post procedural frequency of complete (>70%) resolution of ST segment elevation. RESULTS A complete resolution of ST segment elevation occurred in 51.4% of patients in the thrombectomy group and in 35,6% of those in the conventional-PCI group (P=0.018). Thrombectomy strategy was associated with a lower use of stents. Multivariate analysis identified manual thrombectomy (HR=2.08 IC 95% (1.01-4.26); P=0.046), inferior location and short ischemic delay (<180 min) as independent predictors of ST resolution. The cumulative Kaplan-Meier estimate of MACE was not significantly different between the two groups at one, three years follow-up. CONCLUSION In STEMI patients, manual thrombectomy improves myocardial reperfusion as assessed by the percentage of ST segment resolution and a lower use of stents. However, in this cohort of limited size, this strategy did not translate into an improved cardiovascular outcome at one year follow-up.

Abstract
Acute myocardial infarction was one of the most common causes of death in Germany in 2011. According to the guidelines of the European Society for Cardiology, systemic fibrinolysis and primary percutaneous coronary intervention (PCI) are the methods of choice for acute treatment. Primary PCI should be given priority due to its superiority. The transradial access should be preferred due to the lower bleeding complication rate. In the selection of stents the new generation of drug-eluting stents (DES) are superior to the first generation of bare metal stents (BMS). It has now been demonstrated that the incident rates of DES (e.g. mortality, target vessel revascularization, early and late stent thrombosis and myocardial infarction) are significantly lower. For bioresorbable scaffolds (BRS) long-term results for the use in treatment of ST-elevation myocardial infarction (STEMI) are not yet available but initial results are very promising. However, the selection of a stent needs to be done on an individual basis in order to do justice to all aspects. Data with respect to thrombectomy in acute treatment are heterogeneous. Currently, a thorough consideration of all aspects is necessary because thrombus aspiration can also be associated with an increased rate of incidents. In a state of hemodynamic stability only so-called culprit lesions should currently be treated with a stent. Elective interventions on further stenoses should be carried out after consideration of individual factors and if necessary evaluation of the hemodynamic relevance.

Abstract
In cases of iatrogenic coronary embolism during cardiac surgery or percutaneous coronary intervention, small air bubbles or foreign bodies are directly injected, which usually result in serious adverse events if not treated promptly. We herein describe the case of a patient who developed acute myocardial infarction resulting in shock due to BioGlue® (CryoLife, Atlanta, GA, USA)-induced coronary embolism during the surgical repair of aortic dissection and was treated for retrieval of the material using a thrombectomy catheter. <Learning objective: Coronary embolism caused by surgical adhesives is a rare but potentially life-threatening complication. It is important for surgeons to promptly recognize and treat this serious condition in consultation with cardiologists.>.

Abstract
BACKGROUND The clinical effect of routine intracoronary thrombus aspiration before primary percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI) is uncertain. We aimed to evaluate whether thrombus aspiration reduces mortality. METHODS We conducted a multicenter, prospective, randomized, controlled, open-label clinical trial, with enrollment of patients from the national comprehensive Swedish Coronary Angiography and Angioplasty Registry (SCAAR) and end points evaluated through national registries. A total of 7244 patients with STEMI undergoing PCI were randomly assigned to manual thrombus aspiration followed by PCI or to PCI only. The primary end point was all-cause mortality at 30 days. RESULTS No patients were lost to follow-up. Death from any cause occurred in 2.8% of the patients in the thrombus-aspiration group (103 of 3621), as compared with 3.0% in the PCI-only group (110 of 3623) (hazard ratio, 0.94; 95% confidence interval [CI], 0.72 to 1.22; P=0.63). The rates of hospitalization for recurrent myocardial infarction at 30 days were 0.5% and 0.9% in the two groups, respectively (hazard ratio, 0.61; 95% CI, 0.34 to 1.07; P=0.09), and the rates of stent thrombosis were 0.2% and 0.5%, respectively (hazard ratio, 0.47; 95% CI, 0.20 to 1.02; P=0.06). There were no significant differences between the groups with respect to the rate of stroke or neurologic complications at the time of discharge (P=0.87). The results were consistent across all major prespecified subgroups, including subgroups defined according to thrombus burden and coronary flow before PCI. CONCLUSIONS Routine thrombus aspiration before PCI as compared with PCI alone did not reduce 30-day mortality among patients with STEMI.

Microvascular coronary flow comparison in acute myocardial infarction angioplasty treated with a mesh covered stent (MGUARD stent) versus bare metal stent: MICAMI-MGUARD. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2013; 14:4-8. [PMID: 23337378 DOI: 10.1016/j.carrev.2012.07.006] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2012] [Revised: 07/09/2012] [Accepted: 07/18/2012] [Indexed: 01/11/2023]
Abstract
BACKGROUND Distal embolization of thrombus/platelet aggregates decreases myocardial reperfusion during primary percutaneous coronary intervention (PCI), and is associated with worse immediate and long-term prognosis of patients with ST-elevation myocardial infarction (STEMI). OBJECTIVE Assess the efficacy of a mesh covered stent (MGuard™ stent, MGS) in preventing distal embolization and microvascular reperfusion impairment during primary PCI, compared with a bare metal stent (BMS). METHODS Forty patients with STEMI referred for primary PCI were randomized for stenting the culprit lesion with the MGS (n = 20) or a BMS (n = 20). Blinded experts performed off-line measurements of angiographic epicardial and microvascular reperfusion criteria: TIMI flow grade, myocardial blush, corrected TIMI frame count (cTFC). RESULTS At baseline clinical, angiographic and procedural variables were not different between groups. Post PCI TIMI flow grade was similar in both groups. We observed better myocardial Blush grade in group MGS compared to BMS (median value 3.0 vs 2.5, 2p = 0.006) and cTFC (mean cTFC: MGS 19.65 ± 4.07 vs BMS 27.35 ± 7.15, 2p < 0.001, cTFC mean difference MGS-BMS: 7.7, CI 95%: 3.94 to 11.46). MGS stent group had a higher percentage of successful angioplasty (cTFC ≤ 23: MGS 85% vs BMS 30%, 2p < 0.001). We had two cases of acute stent thrombosis (one for each group) at 30days follow up, but no clinical events at 6 months follow up. CONCLUSIONS In this exploratory study, MGS significantly improved microvascular reperfusion criteria compared with a BMS in primary PCI. However its safety and impact on clinical outcomes should be verified in larger randomized clinical trials.

Abstract
BACKGROUND In ST-elevation myocardial infarction (STEMI), distal embolization of thrombus material often precludes restoration of normal coronary artery flow. Small-scaled studies have demonstrated that intracoronary thrombus aspiration improves flow and myocardial perfusion, but only one larger randomized single-center study has suggested a survival benefit. Thrombus aspiration is widely used in clinical practice and is recommended by international guidelines despite limited evidence. METHODS/DESIGN The Thrombus Aspiration in ST-Elevation myocardial infarction in Scandinavia is a multicenter, prospective, randomized, controlled, clinical open-label trial based on the Swedish angiography and angioplasty registry (SCAAR) platform with blinded evaluation of end points. A total of 5,000 patients with STEMI undergoing primary percutaneous coronary intervention (PCI) will randomly be assigned either to conventional PCI or to thrombus aspiration followed by PCI. SCAAR will be used as the platform for randomization, allowing a broad population of all-comers in the registry network to be enrolled. All follow-up will also be done in SCAAR and other national registries. The primary end point is time to all-cause death at 30 days. DISCUSSION The Thrombus Aspiration in ST-Elevation myocardial infarction in Scandinavia trial is the largest trial to date to evaluate the effect of thrombus aspiration on death following PCI in patients with STEMI. We propose the term randomized clinical registry trial to describe the novel entity of using an online national registry as platform for case records, randomization, and follow-up.

Abstract
BACKGROUND The impact of primary percutaneous coronary intervention (PCI) for acute ST-elevated myocardial infarction (STEMI) on the incidence of ischemic mitral regurgitation (IMR) is unclear. METHODS AND RESULTS Between January 2000 and December 2004, 318 patients presenting with first acute STEMI were enrolled in this study. Two hundred and twelve (66.67%) patients received PCI (PCI group), and 106 age- and Killip class-matched patients received medical management (non-PCI group). The median duration of follow up was 40.46 months. Compared to the non-PCI group, the PCI group had 14.6% (9.9% vs 24.5%) fewer patients with moderate or severe IMR (P<0.001). Univariate analysis demonstrated IMR was significantly associated with advanced age, higher Killip score, and posterior myocardial infarction (MI). Moreover, IMR was strongly associated with a lower left ventricular (LV) ejection fraction, larger left atrial dimension (LAd), and a larger LV end-systolic and LV end-diastolic volumes (LVEDV) (all P<0.01). Multivariate analysis revealed the odds of IMR in the PCI group was 0.208 times those of the non-PCI group (P<0.001). Additionally, moderate or severe IMR was independently correlated with advanced age, inferior MI, Killip class ≥3, larger LAd, and larger LVEDV (all P<0.05). Furthermore, long-term survival time was longer in the PCI group without IMR than in the non-PCI group with IMR (all P<0.01). CONCLUSIONS PCI for first acute STEMI was associated with lower incidence of IMR. Advanced age, inferior MI, Killip class ≥3, larger LAd and LVEDV were risk factors associated with IMR development.

Abstract
The majority of proteasome substrates identified to date are marked for degradation by polyubiquitinylation. Exceptions to this principle, however, are well documented and can help us understand the process proteasomes use to recognize their substrates. Examples include ornithine decarboxylase, p21/Cip1, TCRalpha, IkappaBalpha, c-Jun, calmodulin and thymidylate synthase. Degradation of these proteins can be completely ubiquitin-independent or coexist with ubiquitin-dependent pathways. Uncoupling degradation from ubiquitin modification may reflect the evolutionary conservation of mechanisms optimized for highly specialized regulatory functions.
