Int J Cardiol 2024; 410:132228. [PMID: 38844092 DOI: 10.1016/j.ijcard.2024.132228] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Revised: 05/12/2024] [Accepted: 06/03/2024] [Indexed: 06/16/2024]
Abstract
BACKGROUND no-reflow can complicate up to 25% of pPCI and is associated with significant morbidity and mortality. We aimed to compare the outcomes of intracoronary epinephrine and verapamil with intracoronary adenosine in the treatment of no-reflow after primary percutaneous coronary intervention (pPCI). METHODS 108 STEMI patients had no-reflow during pPCI were assigned into four groups. Group 1, in which epinephrine and verapamil were injected through a well-cannulated guiding catheter. Group 2, in which same drugs were injected in the distal coronary bed through a microcatheter or perfusion catheter. Group 3, in which adenosine was injected through a guiding catheter. Group 4, in which adenosine was injected in distal coronary bed. Primary end point was the achievement of TIMI III flow and MBG II or III. Secondary end point was major adverse cardiovascular and cerebrovascular events (MACCEs) during hospital stay. RESULTS The study groups did not differ in their baseline characteristics. Primary end point was achieved in 15 (27.8%) patients in the guide-delivery arm compared with 34 (63%) patients in the local-delivery arm, p < 0.01. However, the primary end point did not differ between the epinephrine/verapamil group and the adenosine group (27 (50%) vs 22 (40.7%), p = 0.334). The secondary end points were similar between the study groups. CONCLUSION Local delivery of epinephrine, verapamil and adenosine in the distal coronary bed is more effective in achieving TIMI III flow with MBG II or III compared with their guide-delivery in patients who suffered no-reflow during pPCI. There was no difference between epinephrine/verapamil Vs. adenosine.

Intracoronary antithrombotic therapy during primary percutaneous coronary intervention in patients with STEMI: A systematic review and network meta-analysis. Thromb Res 2024; 233:127-134. [PMID: 38041878 DOI: 10.1016/j.thromres.2023.11.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 09/21/2023] [Accepted: 11/20/2023] [Indexed: 12/04/2023]
Abstract
INTRODUCTION The efficacy of intracoronary (IC) antithrombotic therapy, which may best prevent the no-reflow phenomenon during percutaneous coronary intervention (PCI), remains unclear. Therefore, we compared the efficacy and safety of different IC antithrombotic agents. MATERIALS AND METHODS This systematic review and network meta-analysis of randomized controlled trials (RCTs) compared IC fibrinolytic agents (recombinant tissue plasminogen activators [rtPAs] and non-rtPAs) or glycoprotein IIb/IIIa inhibitors (small molecules and monoclonal antibodies) with placebo by searching the relevant studies published before September 21, 2022. Bayesian network meta-analyses were performed using random-effects models. RESULTS Twenty-five RCTs with 4546 patients were included. Non-rtPAs and small molecules were significantly more effective in achieving thrombolysis in myocardial infarction (TIMI) grade 3 flow than placebo (odds ratio [OR] 2.28, 95 % credible intervals [CrI] 1.24-4.13; OR 2.06, 95 % CrI 1.17-3.46). Moreover, these agents' efficacy was observed in other microcirculation-related outcomes, including TIMI myocardial perfusion grade 3, complete ST-segment resolution, and corrected TIMI frame counts. Within 6 months, small molecules were associated with both an improved left ventricular ejection fraction (MD 3.90, 95 % CrI 0.48-7.46) and major adverse cardiac events (MACE) reduction (OR 0.36, 95 % CrI 0.20-0.61). Non-rtPAs demonstrated a reduced MACE incidence within 6 months (OR 0.51, 95 % CrI 0.31-0.81). The results were consistent in the subgroup with a total ischemic time > 6 h. No significant differences in mortality or bleeding events were observed. CONCLUSIONS IC non-rtPAs and small molecules may be effective for adjunctive therapy to PCI, particularly in patients with longer ischemia periods.

Morphological and Physiological Characteristics of Ruptured Plaques in Native Arteries and Neoatherosclerotic Segments: An OCT-Based and Computational Fluid Dynamics Study. Front Cardiovasc Med 2022; 9:890799. [PMID: 35722127 PMCID: PMC9204481 DOI: 10.3389/fcvm.2022.890799] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2022] [Accepted: 05/04/2022] [Indexed: 11/13/2022] Open
Abstract
Background Intravascular imaging has been used to assess the morphology of lesions causing an acute coronary syndrome (ACS) in native vessels (NV) and identify differences between plaques that ruptured (PR) and caused an event and those that ruptured without clinical manifestations. However, there is no data about the morphological and physiological characteristics of neoatherosclerotic plaques that ruptured (PR-NA) which constitute a common cause of stent failure. Methods We retrospectively analyzed data from patients admitted with an acute myocardial infarction that had optical coherence tomography (OCT) imaging of the culprit vessel before balloon pre-dilation. OCT pullbacks showing PR were segmented at every 0.4 mm. The extent of the formed cavity, lipid and calcific tissue, thrombus, and macrophages were measured, and the fibrous cap thickness (FCT) and the incidence of micro-channels and cholesterol crystals were reported. These data were used to reconstruct a representative model of the native and neoatherosclerotic lesion geometry that was processed with computational fluid dynamics (CFD) techniques to estimate the distribution of the endothelial shear stress and plaque structural stress. Result Eighty patients were included in the present analysis: 56 had PR in NV (PR-NV group) and 24 in NA segments (PR-NA group). The PR-NV group had a larger minimum lumen area (2.93 ± 2.03 vs. 2.00 ± 1.26 mm2, p = 0.015) but similar lesion length and area stenosis compared to PR-NA group. The mean FCT (186 ± 65 vs. 232 ± 80 μm, p = 0.009) and the lipid index was smaller (16.7 ± 13.8 vs. 25.9 ± 14.1, p = 0.008) while the of calcific index (8.3 ± 9.5 vs. 2.2 ± 1.6%, p = 0.002) and the incidence of micro-channels (41.4 vs. 12.5%, p = 0.013) was higher in the PR-NV group. Conversely, there was no difference in the incidence of cholesterol crystals, thrombus burden or the location of the rupture site between groups. CFD analysis revealed higher maximum endothelial shear stress (19.1 vs. 11.0 Pa) and lower maximum plaque structural stress (38.8 vs. 95.1 kPa) in the PR-NA compared to the PR-NV model. Conclusion We reported significant morphological and physiological differences between culprit ruptured plaques in native and stented segments. Further research is needed to better understand the causes of these differences and the mechanisms regulating neoatherosclerotic lesion destabilization.

Intracoronary pharmacological therapy versus aspiration thrombectomy in STEMI (IPAT-STEMI): A systematic review and meta-analysis of randomized trials. PLoS One 2022; 17:e0263270.

Abstract
BACKGROUND Thrombus load in STEMI patients remains a challenge in practice. It aggravates coronary obstruction leading to impaired myocardial perfusion, worsened cardiac function, and adverse clinical outcomes. Various strategies have been advocated to reduce thrombus burden. OBJECTIVES This meta-analysis aimed to evaluate the effectiveness of intracoronary-administered thrombolytics or glycoprotein IIb/IIIa inhibitors (GPI) in comparison with aspiration thrombectomy (AT) as an adjunct to percutaneous coronary intervention (PCI) among patients presenting with ST-segment elevation myocardial infarction (STEMI). METHODS A comprehensive literature search for randomized trials that compared intracoronary-administered thrombolytics or GPI with AT in STEMI patients who underwent PCI, was conducted using various databases (e.g., MEDLINE, EMBASE, CENTRALE). Primary outcome was procedural measures (e.g., TIMI flow grade 3, TIMI myocardial perfusion grade (TMPG) 3, Myocardial blush grade (MBG) 2/3, ST-segment resolution (STR)). RESULTS Twelve randomized trials enrolled 1,466 patients: 696 were randomized to intracoronary-administered pharmacological interventions and 553 to AT. Patients randomized to PCI alone were excluded. Thrombolytics significantly improved TIMI flow grade 3 (odds ratio = 3.71, 95% CI: 1.85-7.45), complete STR (odds ratio = 3.64, 95% CI: 1.60-8.26), and TMPG 3 (odds ratio = 5.31, 95% CI: 2.48-11.36). Thrombolytics significantly reduced major adverse cardiovascular events (MACE) (odds ratio = 0.29, 95% CI: 0.13-0.65) without increasing bleeding risk. Trial sequential analysis assessment confirmed the superiority of thrombolytics for the primary outcome. Intracoronary GPI, either alone or combined with AT, did not improve procedural or clinical outcomes. CONCLUSIONS Compared with AT, intracoronary-administered thrombolytics significantly improved myocardial perfusion and MACE in STEMI patients.

Abstract
Plaque rupture leads to a cascade of events culminating in collagen disruption, tissue factor release, platelet activation and thrombus formation. Pro-inflammatory conditions, hyperglycemia and smoking predispose to high thrombus burden (HTB) which is an independent predictor of slow or no-reflow. In patients with acute myocardial infarction (AMI), glycoprotein IIb/IIIa inhibitors (GPI) reduce thrombus burden and improve myocardial perfusion. These agents are typically administered systemically via the intravenous route or locally via an intracoronary (IC) route. However, as higher local concentrations of GPI are associated with enhanced platelet inhibition, intralesional (IL) GPI administration may be particularly effective in cases of HTB. Modest-sized randomized trials comparing IL and IC GPI delivery have reported conflicting outcomes. Some trials have demonstrated improved coronary flow and myocardial perfusion with reduced major adverse cardiac events with IL compared with IC GPI administration, whereas others have shown no significant benefits. Furthermore, although no direct comparison has been made between IL delivery using an aspiration catheter, microcatheter or a dedicated balloon-based "weeping" infusion-catheter, improved outcomes have been most consistent following GPI administration at the site of the lesion and thrombus with the dedicated infusion catheter. This review provides an update on the role and outcomes of IL GPI administration in patients with AMI and HTB. Based on the evidence we offer an algorithm demonstrating when to consider IL administration in patients with AMI undergoing intervention. We conclude with a perspective on the management of patients with STEMI and COVID-19 in whom a prothrombotic state often results in HTB.

Abstract
We compared residual platelet reactivity and post PCI atherothrombotic burden using OFDI in patients successfully treated by primary PCI versus pharmacoinvasive approach (PI) defined as PCI after successful pre-hospital fibrinolysis. Despite pre-hospital P2Y12-inhibitor loading dose, high rates of high on-treatment platelet reactivity were found at the time of PCI in both groups. Primary PCI patients had higher post stenting thrombus burden and lower rates of final normal myocardial blush grade compared to PI. These findings support the use of a pharmacoinvasive reperfusion strategy especially when primary PCI cannot be timely performed.

Abstract
Globally, the incidence of thromboembolic diseases has increased in recent years, accompanied by an increase in patient mortality. Currently, several targeting delivery strategies have been developed to treat thromboembolic diseases. In this review, we discuss the mechanisms of thrombolysis and current anticoagulant drugs, particularly those with targeting capability, highlighting advances in the accurate treatment of thrombolysis with fewer adverse effects. Such approaches include magnetic drug-loading systems combined with molecular imaging to recanalize blood vessels and systems based on chimeric Arg-Gly-Asp (RGD) sequences that can target platelet glycoprotein receptor. With such progress in targeted antithrombotic drugs, targeted thrombolysis treatment shows significant potential benefit for patients.

Abstract
BACKGROUND The effects of intracoronary (IC) thrombolysis therapy in patients with ST-segment elevation myocardial infarction (STEMI) receiving primary percutaneous coronary intervention (PPCI) remain unclear. METHODS The meta-analysis was conducted according to the PRISMA statement. All relevant studies were identified by searching the PubMed, EMBASE, Cochrane Library, and Web of Science, with no time or language limitation. The pooled risk ratio (RR) and weighted mean difference (WMD) with a 95% CI were calculated. RESULTS Nine randomized controlled trials involving a total of 1341 patients were included. Compared with the control group, IC thrombolysis in patients with STEMI could reduce the incidence of major adverse cardiac events (MACE; RR 0.632, 95% CI, 0.474-0.843, P = .002) and improve left ventricular ejection fraction (RR 0.343, 95% CI, 0.178-0.509, P < .001) and myocardial microcirculation. However, there was no difference noted in the mortality (RR 0.759, 95% CI, 0.347-1.661, P = .490). The incidence rate of major bleeding and minor bleeding was comparable between the 2 groups. CONCLUSIONS Intracoronary thrombolysis was associated with improved MACE and myocardial microcirculation in patients with STEMI having PPCI, though it failed to improve mortality.

Abstract
BACKGROUND Suboptimal coronary blood flow after primary percutaneous coronary intervention (PCI) is a complex multifactorial phenomenon. Although extensively studied, defined modifiable risk factors and efficient management strategy are lacking. This study aims to determine the potential causes of suboptimal flow and associated impact on 30-day outcomes in patients presenting with anterior ST-elevation myocardial infarction (STEMI). METHODS We evaluated a total of 1104 consecutive patients admitted to our hospital from January 2016 to December 2018 with the diagnosis of anterior wall STEMI who had primary PCI. RESULTS Overall, 245 patients (22.2%) had final post-PCI TIMI flow ≤2 in the LAD (suboptimal flow group) and 859 (77.8%) had final TIMI-3 flow (optimal flow group). The independent predictors of suboptimal flow were thrombus burden grade (Odds ratio (OR) 1.848; p < 0.001), age (OR 1.039 per 1-year increase; p < 0.001), low systolic blood pressure (OR 1.017 per 1 mmHg decrease; p < 0.001), total stent length (OR 1.021 per 1 mm increase; p < 0.001), and baseline TIMI flow ≤1 (OR 1.674; p = 0.018). The 30-day rates of major adverse cardiovascular events (MACE) and cardiac mortality were significantly higher in patients with TIMI flow ≤2 compared to those with TIMI-3 flow (MACE: adjusted risk ratio [RR] 2.021; P = 0.025, cardiac mortality: adjusted RR 2.931; P = 0.031). CONCLUSION Failure to achieve normal TIMI-3 flow was associated with patient-related (age) and other potentially modifiable risk factors (thrombus burden, admission systolic blood pressure, total stent length, and baseline TIMI flow). The absence of final TIMI-3 flow carried worse short-term clinical outcomes.

Optical coherence tomography imaging after endovascular thrombectomy: a novel method for evaluating vascular injury in a swine model. J Neurosurg 2020; 134:870-877. [PMID: 32059182 DOI: 10.3171/2019.12.jns192881] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2019] [Accepted: 12/09/2019] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Although studies have shown that some degree of iatrogenic endothelial injury occurs during endovascular thrombectomy (EVT), the clinical significance of such injury is uncertain. Furthermore, it is likely that iatrogenic effects such as endothelial denudation, intimal dissection, and tunica media edema will have varying clinical implications. The purpose of this study was to assess the feasibility of endovascular optical coherence tomography (OCT) in quantifying vessel injury in real time after EVT, correlate vessel injury with histological findings, and perform imaging at varying time intervals after EVT to assess the impact of prolonged direct exposure of the vessel to the thrombus. METHODS Yorkshire swine weighing 35-40 kg were selected for use as the animal model, with a total of 9 vessels from 3 swine examined. Thrombectomy was performed using a second-generation stent retriever 1, 3, and 6 hours after thrombus deposition. The presence and degree of denudation of the endothelium, detachment and separation of the layers of the tunic media, hemorrhage within the media, dissection of the vessels, and thrombus within the lumina were assessed using OCT images acquired immediately after EVT. Bland-Altman analysis indicated that these OCT findings were correlated with postmortem histological findings. RESULTS OCT image acquisition was technically successful in all cases. Endothelial denudation was present in 65% ± 16%, 87% ± 8%, and 93% ± 7% of the vessel surface 1, 3, and 6 hours, respectively, after thrombus deposition and subsequent EVT. Residual intraluminal thrombus was present in vessels at all time intervals despite complete angiographic revascularization. Bland-Altman plots showed good agreement between OCT and histological analysis with respect to the degree of endothelial denudation and elevation, separation of the tunica media, and hemorrhage within the media. OCT appears to be more specific than histological analysis in detecting endothelial elevation. CONCLUSIONS OCT is a feasible method that can be used to assess vascular injury after EVT with histological accuracy. Varying degrees of vessel injury occur after EVT, and residual luminal thrombus can be present despite complete angiographic revascularization.

Abstract
BACKGROUND Previous studies have proved that intracoronary injection of eptifibatide is safe and more effective in infarct size reduction and clinical outcomes than intravenously injection in the patients with acute myocardial infarction (AMI). This study aimed to compare the effect of localized and intracoronary injection of eptifibatide on myocardial perfusion improvement and its outcomes. METHODS We conducted a randomized clinical trial study of 60 patients presented with thrombotic AMI. The patients underwent percutaneous coronary intervention (PCI), and were randomly divided into two equal number groups. The first group received two bolus doses of 180 μg/kg eptifibatide through guiding catheter. The second group received the same bolus doses through export aspiration catheter into the coronary lesion directly. Thrombolysis in myocardial infarction (TIMI) flow, myocardial blush grade (MBG), and no-reflow phenomenon were primary end points. Secondary end points were pre- and postprocedure cardiac arrhythmia, in-hospital mortality, adverse effects, reinfection, pre-discharge ventricular systolic function, and re-hospitalization and mortality after 6 month of follow up. RESULTS The mean ages of group I and group II were 58.3 ± 1.8 and 57.0 ±2.0 years, respectively, and most of patient were men (90% in group I and 80% in group II). Postprocedural TIMI flow grade 3 was achieved in 60.0% and 76.7% of the intracoronary and intralesional groups, respectively (P = 0.307). Postprocedural MBG grade 3 was achieved in 53.3% and 70.0% in intracoronary and intralesional groups, respectively (P = 0.479). There was no significant difference between the groups in no-reflow assessment. Moreover, no significant difference was seen between the two groups in secondary end-point analysis. CONCLUSION Both methods of intracoronary and intralesional eptifibatide administration during primary PCI in patients with acute ST-elevation myocardial infarction (STEMI) were safe and similar in myocardial perfusion outcomes.

Abstract
OBJECTIVES We aimed to assess the relationship between residual in-stent atherothrombotic burden (ATB) after primary percutaneous coronary intervention (PCI) measured by optical frequency domain imaging (OFDI) using different measurement methods and myocardial blush grade (MBG). BACKGROUND The impact of residual ATB after primary PCI on myocardial reperfusion remains unclear. METHODS We prospectively included 60 ST-elevation myocardial infarction patients pretreated with aspirin and ticagrelor. OFDI volumetric quantification using planimetry (with intervals every frame or every millimeter) and semiquantitative score were used to determine ATB. Patients were divided into two groups according to final MBG 3 or <3. RESULTS The mean ATB was 10.08 ± 5.21%. ATB was lower in patients with final MBG 3 compared to those with impaired MBG, regardless of the measurement method (8.15 ± 5.58 vs. 11.77 ± 4.28%; p = .007 for quantification per frame; 7.8 ± 5.19 vs. 11.07 ± 4.07%; p = .009 for quantification per mm and 11.21 ± 11.75 vs. 22.91 ± 17.35; p = .003 for the semiquantitative thrombus score, respectively). CONCLUSION Residual post-stenting ATB remains substantial after primary PCI in STEMI patients, even when pretreated with ticagrelor and aspirin. ATB appears as a significant correlate of suboptimal myocardial reperfusion, a known surrogate of clinical outcome.

Abstract
BACKGROUND Dual quantitative coronary angiography (QCA) has been recently tested for assessment of intracoronary thrombus volume in experimental models. The present study aimed to validate dual QCA in vivo for the assessment of thrombus burden by exploring the correlations between dual QCA-thrombus volume and optical coherence tomography (OCT)-derived indices of thrombotic burden. METHODS AND RESULTS Fifty-one patients with ACS and angiographic evidence of thrombus undergoing OCT of the culprit lesion before stenting were included. Dual QCA-thrombus volume was calculated as difference between edge-detection and video-densitometry area functions along the target segment. Culprit lesion was categorized using the Ambrose's and AHA/ACC angiographic classifications. Thrombus volume (mean thrombus area × thrombus length), thrombus burden [(mean thrombus area/mean lumen area) x100] and Prati thrombus score (number of quadrants with thrombus) were measured by OCT, and the presence of plaque rupture (PR) or intact fibrous cap (IFC) was assessed. Dual QCA-thrombus volume correlated significantly with OCT-thrombus volume (R = 0.791), thrombus burden (R = 0.767) and Prati thrombus score (R = 0.600) (all p < 0.001). Dual-QCA thrombus volume was significantly higher in patients with PR compared with those with IFC (3.48 mm3 [1.45-11.26] vs. 1.69 mm3 [0.09-5.02], p = 0.013). Compared with IFC, PR showed higher prevalence of eccentric type II Ambrose lesion (41.7% vs. 7.4%, p = 0.004), complex B2/C lesion (87.5% vs. 55.6%, p = 0.012), and heavy calcification (29.2% vs. 3.7%, p = 0.013). CONCLUSIONS Dual QCA analysis appears to be a promising tool for quantification of intracoronary thrombus in vivo. This novel methodology may be useful to guide intracoronary thrombus removal during percutaneous coronary intervention and to aid prognostic stratification in patients with ACS.

Abstract
Intracoronary thrombus burden affects the quality of myocardial reperfusion in the setting of ST-elevation myocardial infarction (STEMI). We aimed to study the characteristics of the plaque and thrombus assessed by intracoronary optical frequency domain imaging (OFDI) according to the presence of plaque rupture or erosion in STEMI patients treated with successful fibrinolysis. Pre-stenting thrombus and post-stenting atherothrombotic burden were compared between plaque rupture and erosion. Twenty-seven consecutive patients were included: 17 (63%) had OFDI-plaque rupture and 10 (37%) had OFDI-erosion. Thrombus volume and burden were significantly higher in case of rupture compared to erosion at baseline (13.4 ± 18.4 vs 2.8 ± 2.3 mm3; p = 0.03 and 33.8 ± 17.5 vs 17.5 ± 9.9%; p = 0.007, respectively). In the rupture group, the core of the thrombus consisted dominantly of red thrombus evenly distributed along the entire culprit plaque. In the erosion group, it consisted dominantly of white thrombus with a focal distribution near the minimal lumen area zone. After stenting, the atherothrombotic volume, burden and its distribution, as well as angiographic estimators of myocardial reperfusion were similar between groups. Our study showed that pre-PCI thrombus amount, typesetting and distribution are mainly linked to the underlying mechanism of STEMI. After stenting, the atherothrombotic burden and its distribution were similar between the groups.

Potent effect of prasugrel on acute phase resolution of intra-stent athero-thrombotic burden after percutaneous intervention to acute coronary syndrome. J Cardiol 2018; 72:403-410.

Abstract
BACKGROUND Recent studies suggested protruding thrombus and atheroma after stent placement could be a substrate for subsequent adverse ischemic events. Although protruded atherothrombotic burden can be assessed as intra-stent tissue (IST) by optical coherence tomography (OCT), the effects of potent antiplatelet therapy on the acute phase resolution of IST in patients with acute coronary syndrome (ACS) was unknown. METHODS Ninety-six consecutive ACS patients with multi-vessel disease were enrolled in this prospective registry. In combination with aspirin, either clopidogrel or prasugrel was selected according to the date of enrolment. OCT examination was done immediately after percutaneous coronary intervention (post-PCI) and 10 days after index PCI (follow-up acute phase) to calculate averaged IST score as semi-quantitative measures of IST. High residual platelet reactivity (HRPR) was defined as platelet reactivity units (PRU)≥240 by VerifyNow P2Y12 assay (Accumetrics Inc., San Diego, CA, USA). RESULTS Thirty two patients (38 stents) were enrolled in the prasugrel group and sixty four patients (72 stents) in the clopidogrel group. Averaged IST scores post-PCI were similar between the two groups (0.68±0.41 vs. 0.68±0.40, p=0.99), which decreased in all of the prasugrel group and in 87.5% of the clopidogrel group (p=0.02). Consequently, changes in averaged IST score (delta averaged IST score) were significantly greater in the prasugrel group compared to those in the clopidogrel group (-0.411±0.288 vs. -0.299±0.270, p=0.045). The frequency of HRPR was significantly lower in the prasugrel group (10.0% vs 32.4%, p=0.028). CONCLUSIONS Prasugrel plus aspirin achieved greater acute phase reduction of IST than clopidogrel plus aspirin, which might underlie the clinical benefit of potent antiplatelet therapy in ACS.

Abstract
BACKGROUND Manual thrombus aspiration and local drug delivery of abciximab have been proposed as a strategy to reduce thrombus burden during percutaneous coronary intervention in patients with ST elevation myocardial infarction; however, the effectiveness of these approaches, is uncertain. In this COCTAIL II substudy, we compared the effect of these strategies on prestenting and poststenting thrombus burden assessed by optical coherence tomography. PATIENTS AND METHODS COCTAIL II trial enrolled patients with ST elevation myocardial infarction randomized to intralesion (IL, by the ClearWay catheter) versus intracoronary (IC, by the guide catheter) abciximab bolus with or without aspiration thrombectomy (AT). The following parameters were used to quantify atherothrombotic burden: thrombus volume (TVol), maximum thrombus area (TA), and thrombus burden (TB). Primary endpoint was the comparison of prestenting TVol after the use of local drug delivery (group IL+IL abciximab plus AT) versus nonlocal drug delivery (group IC abciximab plus AT+IC). RESULTS The final population consisted of 59 patients undergoing both prestenting and poststenting optical coherence tomography assessment. The amount of thrombus was not significantly different in the groups with local drug delivery of abciximab versus nonlocal drug delivery in both prestenting (TVol: 18.87±26.70 vs. 19.02±18.45; TB: 26.73±12.8 vs. 25.18±13.25; and maximum TA: 59.25±18.84 vs. 53.34±19.30) and poststenting (TVol: 8.46±9.15 vs. 8.05±6.81; TB: 6.68±3.54 vs. 6.24±3.66; and maximum TA: 15.47±7.61 vs. 16.52±11.55) evaluations. A good correlation between thrombus measurements after thrombus removal techniques and intrastent thrombus was observed. CONCLUSION Either local drug delivery of abciximab or manual thrombus aspiration showed comparable results in terms of prestenting and poststenting thrombus burden removal.

Abstract
BACKGROUND Glycoprotein IIb/IIIa inhibitors (GPIs) have been regarded as an adjuvant regimen to deal with no-reflow. However, whether intralesional (IL) administration of GPIs improves myocardial reperfusion without increasing bleeding in patients with acute coronary syndrome (ACS) compared with intracoronary (IC) administration has not been well addressed. Our meta-analysis aimed to evaluate the efficacy and safety of IL versus IC administration of GPIs for patients with ACS during percutaneous coronary intervention. METHODS We systematically searched Medline, Embase, the Cochrane Central Register of Controlled Trials, and Cambridge Scientific Abstracts from January 2007 to May 2017. Thrombolysis in Myocardial Infarction (TIMI) 3 flow, corrected TIMI frame count (CTFC), and complete ST-segment resolution (>70%) were selected as the primary outcomes. Major adverse cardiac events (MACEs) were the secondary outcome, and major bleeding complications were the safety outcome. Data analysis was conducted using the Review Manager 5.3 software. RESULTS Six randomized controlled trials were included in our meta-analysis. Compared with IC, IL obtained better results in terms of TIMI grade 3 flow [odds ratio (OR) 2.29; 95% confidence intervals (CIs) 1.31-4.01; P = .004], CTFC [weighted mean difference (WMD) -4.63; 95% CI -8.82 to -0.43; P = .03], and complete ST-segment resolution (OR 1.55; 95% CI 1.12-2.14; P = .008). There was a trend toward decreased MACE in the IL administration groups, which was not of statistical significance (OR 0.63; 95% CI 0.30-1.31; P = .22). No significant difference was found between the two groups in terms of in-hospital major bleeding events (OR 2.52; 95% CI .66 to 9.62; P = .18). CONCLUSION IL administration yielded favorable outcomes in terms of myocardial tissue reperfusion as evidenced by the improved TIMI flow grade, CTFC, complete ST-segment resolution, and decreased MACE without increasing in-hospital major bleeding events. The IL administration of GPIs can be recommended as the preferred regimen to guard against no-reflow.

Abstract
OBJECTIVES The index of microcirculatory resistance (IMR) provides a reproducible assessment of the status of coronary microvasculature in patients with ST-elevation myocardial infarction (STEMI). Frequency-domain optical coherence tomography (FD-OCT) enables detailed assessment of the morphology of coronary plaque.We sought to determine the influence of the initial culprit coronary plaque anatomy within the infarct-related artery on IMR after stenting in STEMI. PATIENTS AND METHODS In 25 STEMI patients IMR was measured immediately before and after stent implantation. FD-OCT imaging was performed at the same time points and atherothrombotic volume (ATV) before stenting, prolapsed+floating ATV after stenting and ΔATV was measured using three different strategies. RESULTS There were no relationships between preprocedural IMR and FD-OCT parameters. Prestenting IMR was related only to pain to wire time (P: 0.02). Irrespective of the method adopted, the final IMR was related to prestenting ATV (ρ: 0.44, P: 0.03 for method I, ρ: 0.48, P: 0.02 for method II and ρ: 0.30, P: 0.06 for method III) and ΔATV (ρ: 0.41, P: 0.04 for method II and ρ: 0.44, P: 0.03 for method III). CONCLUSION IMR measured before stenting is independent of the appearances of the culprit coronary plaque within the infarct-related artery. IMR after stenting, and more importantly, the change in IMR after stenting, reflect the degree of distal embolization during stent implantation.

Abstract
OBJECTIVES To compare vascular healing after drug-eluting stent (DES) implantation between plaque rupture (PR) and plaque erosion (PE). BACKGROUND Vascular response after stent implantation in patients with PR has been extensively studied. Little is known about vascular healing after stent implantation in PE. METHODS Sixty-five ACS patients who received optical coherence tomography (OCT) imaging of the culprit lesions both before and after stent implantation at baseline as well as at 6 months were included in this study. Patients were divided into two groups: PR (n = 19) and PE (n = 24). Prestent thrombus burden and poststent intrastent structure (ISS) volume were analyzed during the index procedure. The ratio of uncovered to total stent struts per cross-section score (RUTTS) and neointimal thickness and area were measured at follow-up. RESULTS OCT imaging showed that compared with PR, PE showed a significantly lower prestent thrombus score (34.2 ± 19.2 vs. 68.6 ± 44.2, P = 0.009) at baseline and a smaller poststent ISS volume (0.7 ± 0.9 mm3 vs. 2.1 ± 1.9 mm3 , P = 0.019). At the 6-month follow-up, PE showed a higher incidence of RUTTS >0.3 (12.2 ± 14.4 vs. 2.0 ± 4.5%, P = 0.003), thinner neointimal thickness (0.05 ± 0.02 mm vs. 0.12 ± 0.08 mm, P = 0.002), and smaller neointimal area (0.5 ± 0.2 vs. 1.2 ± 0.9 mm2 , P = 0.004) compared with PR. In a multivariate logistic model, PE was identified as an independent predictor for RUTTS >0.3. CONCLUSIONS PE was associated with less favorable healing following DES implantation when compared to PR at 6 months, indicating longer dual-antiplatelet therapy may be necessary for patients with PE. © 2017 Wiley Periodicals, Inc.

Abstract
BACKGROUND Massive intracoronary thrombus is associated with adverse procedural results including failed aspiration and unfavourable reperfusion. We aim to evaluate the effect of the intracoronary administration of antithrombotic agents via a perfusion catheter in patients with ST-segment elevation myocardial infarction (STEMI) presenting with a large thrombus burden and failed aspiration. METHODS We retrospectively analyzed the thrombus burden, the TIMI grade flow, and the myocardial Blush in 25 consecutive STEMI patients with a large thrombus burden and failed manual aspiration, who received intracoronary infusion of glycoprotein IIb/IIIa inhibitors (N=17) or bivalirudine (N=8) via a 6F-infusion catheter (ClearWay™ RX) RESULTS: Mean age was 67±14 years, 16 patients (64 %) presented with anterior STEMI, and 7 (28 %) with cardiogenic shock. Immediately after intracoronary infusion, the TIMI flow grade improved of 2 grades in 7 patients (28 %), and 1 grade in 14 (56 %), a complete resolution of the thrombus was observed in 9 patients, and a >50 % resolution in 12. Blush was improved of 3 grades in 15 patients (60 %), of 2 grades in 7 (28 %), and Blush grade 0 remained in 3. At the end of procedure, we observed normal TIMI 3flow in most patients (92 %), a complete resolution of thrombus in 80 %, and a Blush grade 3 in 68 %. CONCLUSIONS In STEMI patients presenting with a large thrombus burden and failed aspiration, intracoronary administration of glycoprotein IIb/IIIa inhibitors or bivalirudin via the perfusion catheter ClearWay™ RX significantly reduced the thrombus burden and improved the TIMI flow and the Blush grade, without bleeding.

Abstract
BACKGROUND Thrombus burden and distal embolization are predictive of no-reflow during primary percutaneous coronary intervention (PCI) in patients with acute ST-elevation myocardial infarction (STEMI). We sought to compare the efficacy of pharmacological and catheter-based strategies for thrombus in patients with STEMI and high atherothrombotic burden. METHODS Between January 2012 and December 2013, 128 STEMI patients undergoing primary PCI at 5 centers were randomly assigned in a 2 × 2 factorial design to intracoronary (IC) abciximab bolus (via the guide catheter) versus intralesion (IL) abciximab bolus, each with versus without aspiration thrombectomy (AT). Study end points were residual intrastent atherothrombotic burden, defined as the number of cross-sections with residual tissue area >10% as assessed by optical coherence tomography, and indices of angiographic and myocardial reperfusion. RESULTS Residual intrastent atherothrombotic burden did not significantly differ with IL versus IC abciximab (median [interquartile range] 6.0 [1-15] vs 6.0 [2-11], P = .806) and with AT versus no aspiration (6.0 [1-13] vs 6.0 [2-12], P = .775). Intralesion abciximab administration was associated with improved angiographic myocardial reperfusion in terms of thrombolysis in myocardial infarction (TIMI) flow (3 [3-3] vs 3 [2-3], P = .040), corrected TIMI frame count (12 ± 5 vs 17 ± 16, P = .021), and myocardial blush grade (3 [2-3] vs 3 [2-3], P = .035). In particular, IL abciximab was associated with higher occurrence of final TIMI 3 flow (90% vs 73.8%, P = .032) and myocardial blush grade 3 (71.6% vs 52.4%, P = .039). Conversely, AT had no significant effect on indices of angiographic or myocardial reperfusion. CONCLUSIONS In patients with STEMI and high thrombotic burden, neither IL versus IC abciximab nor AT versus no aspiration reduced postprocedure intrastent atherothrombotic burden in patients with STEMI undergoing primary PCI. However, IL abciximab improved indices of angiographic and myocardial reperfusion compared to IC abciximab, benefits not apparent with AT.

Abstract
The success of a primary percutaneous intervention (PCI) in the setting of ST elevation myocardial infarction depends on the functional and structural integrity of coronary microcirculation. Coronary microvascular dysfunction and obstruction (CMVO) occurs in up to half of patients submitted to apparently successful primary PCI and is associated to a much worse outcome. The current review summarizes the complex mechanisms responsible for CMVO, including pre-existing coronary microvascular dysfunction, and highlights the current limitations in the assessment of microvascular function. More importantly, at the light of the substantial failure of trials hitherto published on the treatment of CMVO, this review proposes a novel integrated therapeutic approach, which should overcome the limitations of previous studies.

Abstract
AIMS Manual thrombectomy has been proposed as a strategy to reduce thrombus burden during primary percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI). However, the effectiveness of manual thrombectomy in reducing thrombus burden is uncertain. In this substudy of the TOTAL (ThrOmbecTomy versus PCI ALone) trial, we compared the thrombus burden at the culprit lesion using optical coherence tomography (OCT) in patients treated with thrombectomy vs. PCI-alone. METHODS AND RESULTS The TOTAL trial (N = 10 732) was an international, multicentre, randomized trial of thrombectomy (using the Export catheter, Medtronic Cardiovascular, Santa Rosa, CA, USA) in STEMI patients treated with primary PCI. The OCT substudy prospectively enrolled 214 patients from 13 sites in 5 countries. Optical coherence tomography was performed immediately after thrombectomy or PCI-alone and then repeated after stent deployment. Thrombus quantification was performed by an independent core laboratory blinded to treatment assignment. The primary outcome of pre-stent thrombus burden as a percentage of segment analysed was 2.36% (95% CI: 1.73-3.22) in the thrombectomy group and 2.88% (95% CI: 2.12-3.90) in the PCI-alone group (P = 0.373). Absolute pre-stent thrombus volume was not different (2.99 vs. 3.74 mm(3), P = 0.329). Other secondary outcomes of pre-stent quadrants of thrombus, post-stent atherothrombotic burden, and post-stent atherothrombotic volume were not different between groups. CONCLUSION Manual thrombectomy did not reduce pre-stent thrombus burden at the culprit lesion compared with PCI-alone. Both strategies were associated with low thrombus burden at the lesion site after the initial intervention to restore flow.

Abstract
BACKGROUND Acute or subacute stent thrombosis (ST) is a well-described complication usually causing acute coronary syndromes and, in the worst case scenario, sudden cardiac death. In this study, we aimed at exploring the potential role of optical coherence tomography (OCT) in the understanding of the mechanism of ST. METHODS Twenty-one consecutive patients, after acute coronary syndromes due to a definite subacute ST, were assessed with OCT and matched 1:2 with 42 patients undergoing OCT for scheduled follow-up. Optical coherence tomography assessment was focused on features indicative of nonoptimal stent deployment: underexpansion, malapposition, edge dissection, and reference lumen narrowing. RESULTS Optical coherence tomography revealed a minimum stent area sensibly smaller in the ST group (5.6 ± 2.6 vs 6.8 ± 1.7 mm(2); P = .03) with a higher incidence of stent underexpansion when compared with the control group (42.8% vs 16.7%; P = .05). Dissection at stent edges was more commonly detected in ST group (52.4% vs 9.5%; P < .01). No significant differences between the 2 groups were observed for malapposition (52.4% vs 38.1%; P = .651) and reference lumen narrowing (19.0% vs 4.8%; P = .172). At least 1 OCT finding indicative of suboptimal stent deployment was detectable in 95.2% of patients experiencing ST versus 42.9% of the control group (P < .01). CONCLUSIONS Optical coherence tomography assessment in patients experiencing subacute ST revealed nonoptimal stent deployment in almost all cases with higher incidence of stent underexpansion and edge dissection, potentially explaining the cause of this adverse event. The adoption of an OCT-guided percutaneous coronary intervention protocol could have a potential for the prevention of ST in complex cases.

Abstract
BACKGROUND Abciximab reduces major adverse cardiac events in patients with ST elevation myocardial infarction undergoing primary percutaneous coronary intervention (pPCI). Standard protocol is intravenous abciximab bolus during PCI plus abciximab infusion for 12-18 h post pPCI. Intracoronary (IC) abciximab bolus administration results in high local drug concentrations and hence it should have higher antiplatelet effect. In this study, we assess the short-term efficacy and safety of IC compared to IV bolus of abciximab in ACS patients during pPCI. METHODS We compared the clinical outcomes between the IC (n = 56) and standard protocol (n = 170) group of patients. Primary endpoints included bleeding/vascular/ischemic complications and MACE. RESULTS The two groups were similar with respect to baseline characteristics. IC abciximab bolus only reduced bleeding complications, with no moderate bleed versus 7.2% in standard protocol group (p value 0.04). Ischemic/vascular complications had statistically insignificant difference between the two groups. CONCLUSION We found no significant difference between IC abciximab bolus only and standard abciximab therapy in terms of ischemic/vascular complications and MACE. But there was higher risk of moderate bleed in standard therapy group. The IC bolus route of abciximab may be superior to the intravenous route. Prospective randomized trials are warranted to validate these findings.

Abstract
BACKGROUND Patients with ST-elevation myocardial infarction (STEMI) are at substantial risk of suboptimal procedural results and late adverse events. Angiography and optical coherence tomography (OCT) studies have identified residual coronary thrombus and microcirculatory injury as potential culprits for these adverse outcomes. We hypothesized that coronary thrombectomy and local infusion of glycoprotein IIb/IIIa inhibitors by means of a dedicated infusion device can synergistically improve results of percutaneous coronary intervention (PCI) for STEMI, as appraised by OCT. METHODS A total of 128 patients with STEMI will be randomized, to one of the following: abciximab infusion with the ClearWay coronary catheter (C), standard abciximab infusion (A), thrombectomy followed by abciximab infusion with the ClearWay catheter (T+C), or thrombectomy followed by standard abciximab infusion (T+A). The primary objective is to demonstrate that abciximab infusion with the ClearWay catheter with or without manual thrombus aspiration (groups C or T+C) will result in a significant reduction of intrastent thrombus formations when compared with intravenous or intracoronary abciximab with or without thrombectomy (groups A or T+A). The primary endpoint will be the number of cross-sections with thrombus area more than 10% immediately after stent implantation as assessed with OCT. Additional angiographic, ECG and clinical endpoints will be collected and adjudicated. CONCLUSION This trial will provide important mechanistic insights on the most appropriate invasive treatment strategy for patients with STEMI and significant thrombus burden, by exploiting its factorial design and reliance on sensitive OCT endpoints.

Abstract
Glycoprotein IIb-IIIa (GPIIb-IIIa) antagonists have the capacity to destabilize coronary thrombi and restore vessel patency. Antagonist concentration and residence time, which can be increased by local intracoronary (LIC) administration, and thrombus age may be key factors that influence thrombus stability. Light transmission aggregometry was used to examine the effects of exposing human platelet aggregates to extremely high local levels of GPIIb-IIIa antagonists versus conventional therapeutic levels in vitro. Freshly-formed or aged platelet aggregates were subjected to GPIIb-IIIa antagonists (abciximab, eptifibatide) or direct thrombin inhibitor bivalirudin at concentrations simulating either conventional intravenous (IV) or LIC administration. The degree of antagonist-induced disaggregation was significantly higher using elevated (LIC) doses versus conventional (IV) doses (60.1 % vs. 7.4 % for abciximab, 41.6 % or 45.3 % vs. 17.6 % for eptifibatide, p < 0.01). Bivalirudin did not promote disaggregation. Microscopy confirmed noticeably smaller, more dispersed aggregates for antagonist LIC treatments. Dosing at LIC levels also induced more disaggregation than IV levels when aggregates were aged for 30 min prior to exposure. An in vitro perfusion model was used to simulate the fluid dynamics of IV or LIC administration of abciximab using a microporous local drug delivery balloon catheter such as the Atrium ClearWay™ RX. The perfusion model resulted in more rapid thrombus clearance with LIC dosing levels compared to IV. In summary, boosting the concentration of GPIIb-IIIa antagonists enhances dispersal of human platelet aggregates in vitro. These data provide a foundation for investigating increased local concentrations of GPIIb-IIIa antagonists in patients, as with LIC administration.

Abstract
The detachment of atherothrombotic material from the atherosclerotic coronary plaque and downstream embolisation is an underrecognized phenomenon and it causes different degrees of impairment of the coronary microcirculation. During treatment of obstructive atherosclerotic plaque by percutaneous coronary intervention (PCI) distal embolisation (DE) is considered to be inevitable and it is associated with potential clinical and prognostic implications. This review aims to assess the main aspects of both spontaneous and procedural DE, analyze their different pathophysiology, provide specific insights on the main diagnostic tools for their identification, and finally focus on the main strategies for their treatment and prevention.

Abstract
Thrombus aspiration during percutaneous coronary intervention can result in improved rates of normal epicardial flow and myocardial perfusion, but several unmet needs remain. The purpose of the Delivery of thrombolytIcs before thrombectomy in patientS with ST-segment elevatiOn myocardiaL infarction Undergoing primary percuTaneous coronary interventION (DISSOLUTION) trial was to evaluate the hypothesis that local delivery of thrombolytics can enhance the efficacy of thrombus aspiration in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention. A total of 102 patients with ST-segment elevation myocardial infarction and angiographic evidence of massive thrombosis in the culprit artery were randomly assigned to receive a local, intrathrombus bolus of 200,000 U of urokinase (n = 51) or saline solution (n = 51) by way of an infusion microcatheter, followed by manual aspiration thrombectomy. The end points included the final Thrombolysis In Myocardial Infarction flow grade and frame count, myocardial blush grade, 60-minute ST-segment resolution >70%, and major adverse cardiac and cerebrovascular events, defined as the death, reinfarction, stroke, or clinically driven target vessel revascularization at 6 months. The use of intrathrombus urokinase was associated with a significantly higher incidence of Thrombolysis In Myocardial Infarction flow grade 3 (90% vs 66%, p = 0.008) and lower postpercutaneous coronary intervention Thrombolysis In Myocardial Infarction frame count (19 ± 15 vs 25 ± 17, p = 0.033). The postprocedural myocardial perfusion was significantly increased with the use of urokinase (myocardial blush grade 2 or 3, 68% vs 45%, p = 0.028), with more patients showing ST-segment resolution >70% (82% vs 55%, p = 0.006). At 6 months of follow-up, the patients treated with intrathrombus urokinase showed a better major adverse cardiac event-free survival (6% vs 21%; log-rank p = 0.044). In conclusion, local, intrathrombus delivery of thrombolytics before manual thrombectomy improved the postprocedural coronary flow and myocardial perfusion and the 6-month clinical outcomes.

Abstract
BACKGROUND Despite restoration of epicardial flow during primary PCI in STEMI, microvascular obstruction may persist as a result of both atheromatous and thrombotic embolization and vasospasm. Compared with the systemic administration of IV pharmaco-therapies, highly localized administration of intracoronary pharmacotherapy may be associated with a several-hundred-fold increase in the local concentration of an agent in the epicardial artery and microcirculation. Despite restoration of epicardial flow during primary PCI in STEMI, microvascular obstruction may persist as a result of both atheromatous and thrombotic embolization and vasospasm. We are presenting our experience with use of intracoronary abciximab using local drug delivery catheter in STEMI patients. METHODS We retrospectively evaluated 15 patients presented to us with STEMI undergoing primary PCI between March 2011 and September 2012 who had super selective intracoronary abciximab using local drug delivery catheter. With standard antiplatelet therapy, both Pre and Post TIMI flow, TMP grading were assessed. RESULTS Mean age was 55 years. The TIMI flow increased by 3 grades in thirteen patients, TMP grading increased by 2 grades in five patients and by 3 grades in nine patients. Thus TIMI flow and TMP grading improved after super selective intracoronary abciximab. CONCLUSION Super selective intracoronary abciximab using local drug delivery catheter during primary PCI in STEMI patients significantly improves TMP grading without increased risk of bleeding. This benefit is achieved even in patients without thrombus aspiration. We need to assess the long-term outcomes in the form of reduction in infarct size using this strategy in large group of patients.

Abstract
Postprocedural myocardial infarction is an ominous complication of percutaneous coronary intervention (PCI). Despite several patient, lesion, and procedural factors that may affect its occurrence and severity, it is unclear if implanting a stent edge on a coronary lipid pool, as appraised by optical coherence tomography (OCT), adversely affects outcomes. The aim of this study was to assess the association between postprocedural myocardial infarction and the implantation of a stent edge on a lipid pool, as assessed by OCT. A database was screened for patients without ongoing myocardial infarctions; who underwent PCI with stenting for single, native, de novo lesions; without periprocedural side-branch occlusion or compromise; who underwent post-PCI OCT; and had postprocedural myocardial infarctions. These subjects were matched 1:1 with patients with similar features but without postprocedural myocardial infarctions. Plaque characterization with OCT was performed using established criteria. Specifically, lipid pools within stent edges were quantified by computing the number of involved quadrants and the degree of lipid arc on cross-sectional images. A total of 30 patients were included (15 with postprocedural myocardial infarctions and 15 controls without infarctions). Whereas no patient or control subject had lipid pools in correspondence to distal stent edges, landing of proximal stent edges on lipid pools was significantly more frequent in patients than in controls (10 [66%] vs 2 [13%], p = 0.009), Moreover, patients with postprocedural myocardial infarctions had more extensive lipid pools at proximal stent edges than those without postprocedural myocardial infarctions. Accordingly, lipid pool arc at proximal stent edge was significantly associated with peak post-PCI creatine kinase-MB/upper limit of normal ratio (Spearman's ρ = 0.49, p = 0.006). In conclusion, incomplete stent coverage of coronary lipid pools appears to be associated with an increased risk for postprocedural myocardial infarction in patients who undergo PCI.
