Abstract
Purpose The prognostic implications of calcified versus non-calcified tissue protrusions (TPs) following stent implantation remain undetermined. This study aimed to evaluate the differential clinical outcomes associated with calcified and non-calcified TP morphologies. Patients and Methods Employing intravascular ultrasound (IVUS), we identified calcified TPs as calcium fragment extrusions permeating the stent struts, while non-calcified TPs were characterized as plaque and/or thrombus extensions through the stent into the arterial lumen. The primary endpoint encompassed target lesion failure (TLF), comprising cardiac death, target vessel myocardial infarction, clinically driven target lesion revascularization (TLR), or stent thrombosis, assessed in patients with a follow-up period exceeding one year. Results Of 1033 patients subjected to pre- and post-intervention IVUS, 62 exhibited calcified TPs (6.0%), and 279 presented non-calcified TPs (27.0%), forming the basis of this analysis. Multivariable linear regression indicated calcified nodules as a significant predictor of calcified TP [Odds Ratio (OR) 2.47; 95% Confidence Interval (CI) 2.33 to 2.62; P <0.001], with ST-segment elevation myocardial infarction emerging as an inverse correlate [OR 0.82; 95% CI 0.73 to 0.93; P = 0.004]. Two-year data revealed a higher incidence of TLF in patients with calcified TPs versus their non-calcified counterparts (11.3% vs 2.2%, P <0.001), and a marked increase in clinically driven TLR (9.7% vs 1.4%, P <0.001). Calcified TPs were independently correlated with increased TLF risk in the adjusted model [Hazard Ratio (HR) 2.47; 95% CI 1.17 to 5.16; P = 0.027]. Conclusion After drug-eluting stent implantation, IVUS-identified calcified TPs correlate with adverse clinical outcomes compared to non-calcified TP formations.

Abstract
BackgroundMicroRNAs (miRNA, miR) have an undeniable physiological and pathophysiological significance and act as promising novel biomarkers. The aim of the study was to investigate blood-derived miRNAs and their association with long-term all-cause mortality in patients with multivessel disease (MVD) suffering from acute coronary syndrome (ACS).Materials and MethodsThis study was an observational prospective study, which included 90 patients with MVD and ACS. Expression of miR-125a, miR-125b, and miR-223 was analysed by polymerase chain reaction (PCR). Patients were followed-up for a median of 7.5 years. All-cause mortality was considered as the primary endpoint. Adjusted Cox-regression analysis was performed for prediction of events.ResultsElevated expression of miR-125b (>4.6) at the time-point of ACS was associated with increased long-term all-cause mortality (adjusted [adj.] hazard ratio [HR] = 11.26, 95% confidence interval [95% CI]: 1.15–110.38; p = 0.038). The receiver operating characteristic (ROC) analysis showed a satisfactory c-statistics for miR-125b for the prediction of long-term all-cause mortality (area under the curve [AUC] = 0.76, 95% CI: 0.61–0.91; p = 0.034; the negative predictive value of 98%). Kaplan–Meier time to event analysis confirmed an early separation of the survival curves between patients with high vs low expression of miR-125b (p = 0.003). An increased expression of miR-125a and miR-223 was found in patients with non-ST-segment elevation ACS (NSTE-ACS) as compared to those with ST-segment elevation myocardial infarction (STEMI) (p = 0.043 and p = 0.049, respectively) with no difference in the expression of miR-125b between the type of ACS.ConclusionIn this hypothesis generating study, lower values of miR-125b were related to improved long-term survival in patients with ACS and MVD. Larger studies are needed to investigate whether miR-125b can be used as a suitable predictor for long-term all-cause mortality.

Elevated levels of sIL-2R, TNF-α and hs-CRP are independent risk factors for post percutaneous coronary intervention coronary slow flow in patients with non-ST segment elevation acute coronary syndrome. Int J Cardiovasc Imaging 2022; 38:1191-1202.

Abstract
To evaluate the association between circulating levels of inflammatory cytokines and the occurrence of post-percutaneous coronary intervention (PCI) coronary slow flow (CSF) in patients with non-ST segment elevation acute coronary syndrome (NSTE-ACS). CSF after PCI commonly occurs and implies poor outcomes, while the determinants of post-PCI CSF in patients with NSTE-ACS remain controversial. In this multicenter case control study, 176 patients diagnosed with NSTE-ACS and with post-PCI CSF occurred composed of CSF group, while 352 matched NSTE-ACS patients composed control group. Corrected thrombolysis in myocardial infarction frame count (cTFC), circulating levels of inflammatory cytokines and PCI related parameters were analyzed using Logistic regression models. Among 528 patients with median age of 67 (59-76) and male proportion of 65.5%, 176 (35.0%) patients had occurrence of post-PCI CSF defined as cTFC ≥ 24. Patients with CSF presented more intense inflammatory activity revealed by higher levels of white blood cell, high-sensitivity C-reactive protein (hs-CRP), interleukin-1ß (IL-1ß), soluble IL-2 receptor (sIL-2R), IL-6, IL-8, IL-10 and tumor necrosis factor-α (TNF-α), while PCI related parameters were comparable. Correlation analysis showed cTFC was positively correlated with those inflammatory cytokines. Logistic regression model indicates that hs-CRP (odds ratio (OR) = 3.038, 95% confidence interval (CI) 1.545-5.975), sIL-2R (OR = 2.103, 95% CI 1.959-4.026) and TNF-α (OR = 3.708, 95% CI 1.426-9.641) were valuable predictors for CSF occurrence. Elevated circulating levels of inflammatory cytokine including hs-CRP, sIL-2R and TNF-α rather than PCI related parameters could predict post-PCI CSF in patients with NSTE-ACS.

Abstract
Arteriosclerosis is an important age-dependent disease that encompasses atherosclerosis, in-stent restenosis (ISR), pulmonary hypertension, autologous bypass grafting and transplant arteriosclerosis. Endothelial dysfunction and the proliferation of vascular smooth muscle cell (vSMC)-like cells is a critical event in the pathology of arteriosclerotic disease leading to intimal-medial thickening (IMT), lipid retention and vessel remodelling. An important aspect in guiding clinical decision-making is the detection of biomarkers of subclinical arteriosclerosis and early cardiovascular risk. Crucially, relevant biomarkers need to be good indicators of injury which change in their circulating concentrations or structure, signalling functional disturbances. Extracellular vesicles (EVs) are nanosized membraneous vesicles secreted by cells that contain numerous bioactive molecules and act as a means of intercellular communication between different cell populations to maintain tissue homeostasis, gene regulation in recipient cells and the adaptive response to stress. This review will focus on the emerging field of EV research in cardiovascular disease (CVD) and discuss how key EV signatures in liquid biopsies may act as early pathological indicators of adaptive lesion formation and arteriosclerotic disease progression. EV profiling has the potential to provide important clinical information to complement current cardiovascular diagnostic platforms that indicate or predict myocardial injury. Finally, the development of fitting devices to enable rapid and/or high-throughput exosomal analysis that require adapted processing procedures will be evaluated.

Abstract
BACKGROUND There is a lack of a comprehensive picture of plaque geometry and composition of unstable atherosclerotic lesions as observed with intravascular ultrasound techniques. We analysed through a systematic review with meta-analysis 39 characteristics of atherosclerotic plaques in three scenarios involving culprit and non-culprit lesions from acute coronary syndromes vs stable angina pectoris patients, and culprit vs non-culprit lesions in acute coronary syndromes patients. METHODS A systematic search of PubMed and EMBASE, from inception to April 2020 was performed. The combined odds ratios or mean differences of all IVUS characteristics were calculated with random-effects models. RESULTS Twenty-eight studies involving 5434 subjects, and 5618 lesions were included. Culprit lesions in acute coronary syndromes have larger plaque areas and remodeling indexes (MD = 0.13 [0.08; 0.17], p < 0.001) and contained larger necrotic cores (MD = 0.67 (95% CI 0.19;1.15), p = 0.006) that stable angina culprit lesions. In acute patients, culprit plaques were also more remodeled, had larger necrotic cores and had more frequently a Thin-Cap Fibroatheroma morphology (OR = 1.79 (95% CI 1.21; 2.65), p = 0.004) than non-culprit lesions. Non-culprit lesions in acute syndromes were more often ruptured (OR = 2.25 (95% CI:1.05; 4.82), p = 0.037) or Thin-Cap Fibroatheromas than in stable angina. CONCLUSION Culprit lesions from acute coronary patients are larger, more positively remodeled and contained more lipids as compared to stable angina lesions or non-culprit in acute patients. Non culprit lesions are also more often complicated or vulnerable in acute than stable patients.

Abstract
OBJECTIVES This study aimed to investigate the pancoronary plaque vulnerability (including culprit and nonculprit lesions) and layered phenotype in patients with ST-segment elevation myocardial infarction (STEMI) vs non-STEMI (NSTEMI). BACKGROUND Pancoronary vulnerability should account for distinct clinical manifestations of acute myocardial infarction (AMI). Layered plaque is indicative of previous coronary destabilization and thrombosis. METHODS A total of 464 patients with AMI who underwent 3-vessel optical coherence tomography imaging were consecutively studied and divided into a STEMI group (318 patients; 318 culprit and 1,187 nonculprit plaques) and a NSTEMI group (146 patients; 146 culprit and 560 nonculprit plaques). Patients were followed up for a median period of 2 years. RESULTS Compared with NSTEMI, culprit lesions in STEMI had more plaque rupture, thrombus, thin-cap fibroatheroma (TCFA), calcification, macrophage accumulation, and microvessels. The prevalence of plaque rupture (8.2% vs 4.8%; P = 0.018), microvessels (57.5% vs 45.2%; P < 0.001), and calcification (40.7% vs 30.2%; P = 0.003) at nonculprit lesions was higher in STEMI than NSTEMI. The layer area and thickness at the culprit and nonculprit lesions were significantly larger in STEMI than in NSTEMI. Multivariate analyses showed that culprit layer area (odds ratio: 1.443; 95% CI: 1.138-1.830; P = 0.002) was predictive of STEMI (vs NSTEMI), in addition to culprit TCFA, culprit thrombus, and non-left circumflex artery location of the culprit lesion. Although the type of AMI was not related to clinical outcomes, high-sensitivity C-reactive protein, culprit calcified nodule, and nonculprit TCFA predicted the 2-year major adverse cardiovascular events in patients with AMI. CONCLUSIONS Patients with STEMI had increased plaque vulnerability (ie, more plaque rupture and microvessels) and distinct layered phenotype at the culprit and nonculprit lesions compared with NSTEMI patients. Culprit lesion features of large layer area, TCFA, thrombus, and non-left circumflex artery location predicted the clinical presentation of STEMI.

Abstract
BACKGROUND This study aims to investigate the association between hemoglobin and major adverse cardiac events (MACE) in patients with stable coronary artery disease (CAD) who were treated with percutaneous coronary intervention (PCI). METHODS This was a secondary analysis based on a retrospective cohort study involving 204 patients with stable CAD. Patients were divided into four groups according to hemoglobin levels (Q1: 6.90-12.30 g/dL; Q2: 12.40-13.80 g/dL; Q3: 13.90-14.90 g/dL; Q4: 15.00-19.00 g/dL). Lasso regression analysis was performed to select characteristic variables and reduce dimensions. Odds ratio (OR) and 95% confidence interval (CI) were used for comparing data among groups. RESULTS After an average follow-up of 783 days, 28/204 (17.72%) patients with CAD occurred MACE. Univariate analysis data showed that hemoglobin level was negatively associated with the incidence of MACE in patients with CAD treated with PCI (Q2 vs Q1: OR=0.19, P=0.005; Q3 vs Q1: OR=0.25, P=0.013; Q4 vs Q1: OR=0.13, P=0.002). The negative correlation between hemoglobin and MACE still existed after adjusting selected variables obtained from multivariate regression analysis (Q2 vs Q1: OR= 0.18, P=0.007; Q3 vs Q1: OR=0.29, P=0.038; Q4 vs Q1: OR=0.19, P=0.016). Curve fitting illustrated that hemoglobin level presented a non-linear and negative association with MACE in patients with CAD treated with PCI. CONCLUSIONS Hemoglobin level can be utilized as a prognostic indicator of MACE in patients with CAD after PCI.

Abstract
BACKGROUND Randomized trials have confirmed that intravascular ultrasound (IVUS) guidance for percutaneous coronary interventions (PCI) improves long-term clinical outcomes. However, data on real-world utilization of IVUS in ST-elevation myocardial infarction (STEMI) and the impact on short to mid-term outcomes are scarce. We sought to evaluate the utilization and the readmission rates for IVUS-guided PCI in the setting of STEMI. METHODS Hospitalizations with a primary diagnosis of STEMI undergoing PCI were included from the Nationwide Readmissions Database (NRD) during 2012-2017. RESULTS Among 809,601 hospitalizations with STEMI undergoing PCI, 33,644 (4.2%) underwent IVUS-guided PCI. IVUS use increased from 4.2% in 2012 to 5.6% in 2017 (p < .0001). After matching, in-hospital mortality was significantly lower with IVUS use (3.9% vs. 4.6%, p < .0001). The overall readmission rates were similar in both groups. We found that readmission rates due to acute MI at 6 months (5.7% vs. 6%, p = .045) and 11 months (5.1% vs. 6.5%, p = .005) as well as the PCI and mortality rates during readmission at 11 months (2.1% vs. 3%, p = .008, and 0.7% vs. 1.4%, p = .002, respectively) were significantly lower in the IVUS group. CONCLUSIONS The utilization of IVUS in STEMI appears to be slowly increasing. Although overall readmission rates were similar, IVUS was associated with lower in-hospital mortality, lower rates of readmission due to acute MI at 6 and 11 months, as well as lower PCI and mortality at 11 months. Randomized trials evaluating long-term benefits of IVUS in STEMI are needed.

Circulating Levels of Dephosphorylated-Uncarboxylated Matrix Gla Protein in Patients with Acute Coronary Syndrome. Molecules 2021; 26:1108. [PMID: 33669806 PMCID: PMC7922740 DOI: 10.3390/molecules26041108] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2021] [Revised: 02/14/2021] [Accepted: 02/17/2021] [Indexed: 12/20/2022] Open
Abstract
Vascular calcification contributes to the pathogenesis of coronary artery disease while matrix Gla protein (MGP) was recently identified as a potent inhibitor of vascular calcification. MGP fractions, such as dephosphorylated-uncarboxylated MGP (dp-ucMGP), lack post-translational modifications and are less efficient in vascular calcification inhibition. We sought to compare dp-ucMGP levels between patients with acute coronary syndrome (ACS), stratified by ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI) status. Physical examination and clinical data, along with plasma dp-ucMGP levels, were obtained from 90 consecutive ACS patients. We observed that levels of dp-ucMGP were significantly higher in patients with NSTEMI compared to STEMI patients (1063.4 ± 518.6 vs. 742.7 ± 166.6 pmol/L, p < 0.001). NSTEMI status and positive family history of cardiovascular diseases were only independent predictors of the highest tertile of dp-ucMGP levels. Among those with NSTEMI, patients at a high risk of in-hospital mortality (adjudicated by GRACE score) had significantly higher levels of dp-ucMGP compared to non-high-risk patients (1417.8 ± 956.8 vs. 984.6 ± 335.0 pmol/L, p = 0.030). Altogether, our findings suggest that higher dp-ucMGP levels likely reflect higher calcification burden in ACS patients and might aid in the identification of NSTEMI patients at increased risk of in-hospital mortality. Furthermore, observed dp-ucMGP levels might reflect differences in atherosclerotic plaque pathobiology between patients with STEMI and NSTEMI.

Abstract
Despite consistent clinical data supporting the use of intravascular imaging with percutaneous coronary intervention, utilization remains low. A practical and standardized approach to incorporating intravascular imaging with percutaneous coronary intervention may overcome the barriers to utilization. This review focuses on basic image interpretation with intravascular ultrasound and optical coherence tomography and proposes an algorithmic approach to stent sizing and optimization. Incorporation of this strategic method for percutaneous coronary intervention may aid in the greater adoption of intravascular imaging for percutaneous coronary intervention.

Abstract
Background We compared the in-hospital complications, outcomes, cost, and length of stay (LOS) between angiography-guided percutaneous coronary intervention (PCI) and intravascular ultrasound (IVUS)-guided PCI in patients with ST-elevation myocardial infarction (STEMI) in the USA. Methods A nationwide inpatient database was queried to identify patients >18 years with STEMI who underwent angiography-guided and IVUS-guided PCI from January 2016 to December 2016. We compared the in-hospital mortality, complications, cost, and LOS between the two groups. Results We identified 100,485 patients who underwent angiography-guided PCI and 5,460 patients who underwent IVUS-guided PCI. In-hospital mortality was not statistically different (odds ratio [OR] 0.76, 95% CI 0.46 − 1.22, P = 0.24). Patients who underwent PCI with IVUS were more likely to have coronary artery dissection (OR 4.26, 95% CI 2.34 − 7.7, p = <0.01), and both groups had a similar incidence of acute kidney injury requiring hemodialysis. The mean LOS was similar, but the mean total cost was higher in the group that underwent PCI under IVUS guidance. Conclusions The in-hospital mortality, hemodialysis, and the use of support devices did not reach a statistical difference between the two groups. However, we observed higher rates of coronary dissection with the use of IVUS in STEMI management.

Abstract
BACKGROUND Studies comparing the clinical outcomes of second-generation biodegradable polymer drug-eluting stents (BP-DES) and second-generation durable polymer drug-eluting stents (DP-DES) in patients with ST-segment elevation myocardial infarction (STEMI) with follow-up duration of more than 1 year are still limited. OBJECTIVE This study aimed to compare the 2-year clinical outcome of BP-DES with second-generation DP-DES in patients undergoing primary percutaneous coronary intervention (PPCI). METHODS This is a retrospective cohort study in patients with STEMI, the primary endpoint was major adverse cardiac events (MACE) defined as recurrent myocardial infarction, total repeat revascularisation and cardiac death. The secondary endpoint was stent thrombosis (ST) defined as definite, probable or possible. RESULTS A total of 400 patients were analysed (197 BP-DES groups and 203 DP-DES groups). BP-DES were independently associated with lower incidence of MACE (adjusted HR 0.67, 95% CI 0.21 to 0.91, p=0.005) and ST (adjusted HR 0.62, 95% CI 0.19 to 0.73, p<0.016) within 2 years of follow-up. Subgroup analysis of MACE individual components showed that BP-DES were associated with lower cardiac deaths (HR 0.35; 95% CI 0.18 to 0.94; p<0.001) compared to DP-DES, but not recurrent myocardial infarction and total repeat revascularisation. CONCLUSIONS BP-DES were associated with better clinical outcomes compared to second-generation DP-DES in patients with STEMI undergoing PPCI.

PLoS One 2019; 14:e0220841.

Abstract
OBJECTIVE This study aimed to compare the levels of plasma neutrophil gelatinase-associated lipocalin (NGAL), matrix metalloproteinase (MMP)-9, high-sensitivity C-reactive protein (hs-CRP), and interleukin (IL)-1β across different clinical presentations of coronary artery disease and to evaluate the relationship between those biomarkers and the severity of coronary artery lesions in patients without kidney disease. METHODS We examined 365 eligible patients who underwent coronary angiography. A total of 124 ST-segment elevation myocardial infarction (STEMI) patients, 117 stable angina pectoris (SAP) patients and 124 patients without atherosclerotic plaques were enrolled in the study. Plasma NGAL, MMP-9, hs-CRP, and IL-1β were measured in all patients using the enzyme-linked immunosorbent assay (ELISA) method. According to the SYNTAX score, the STEMI patients and SAP patients were divided into another set of 2 groups: a high score group (≥ 33, n = 29) and a low score group (<33, n = 212). The relationship between those biomarkers and the severity of coronary stenosis was examined by Spearman correlation analysis; the ability for NGAL to discriminate severe coronary stenosis was examined by receiver operating characteristic (ROC) curve; the influencing factors for the SYNTAX score were determined by logistic regression analysis. RESULTS Plasma NGAL, MMP-9, and hs-CRP levels in STEMI patients were higher than in the SAP patients and control subjects (P<0.05, respectively), and plasma NGAL and hs-CRP levels were significantly higher in the SAP patients than in control subjects (P<0.05, respectively), while plasma IL-1β was similar among the 3 groups (P>0.05, respectively). The SYNTAX score was positively related to NGAL (r = 0.363, P<0.001), MMP-9 (r = 0.377, P<0.001), and hs-CRP (r = 0.163, P<0.011); the SYNTAX score was not related to IL-1β (r = -0.043, P = 0.510). Plasma NGAL was positively related to MMP-9 (r = 0.601, P<0.001) and IL-1β (r = 0.159, P = 0.014). The area under the ROC curve for NGAL discriminating severe coronary stenosis was 0.838 (95% CI: 0.752-0.923, P<0.001), which was greater than that for MMP-9 [0.818, (95% CI: 0.724-0.912, P<0.001)], IL-1β [0.485, (95% CI: 0.369-0.601, P = 0.791)], and hs-CRP [0.607, (95% CI: 0.492-0.722, P = 0.061)]. Multivariate regression analysis showed that plasma NGAL levels were independently related to high SYNTAX scores [OR = 1.109, (95% CI: 1.104-1.114), P<0.001]. CONCLUSION Plasma NGAL, MMP-9, and hs-CRP levels in STEMI patients were higher than those in the SAP patients and control subjects. NGAL had a better ability to discriminate severe coronary stenosis than MMP-9, IL-1β, and hs-CRP. NGAL may be a novel biomarker to aid in risk stratification in coronary heart disease patients.

Abstract
Background Dual antiplatelet therapy (DAPT) in patients presenting with acute coronary syndrome (ACS) undergoing CABG is recommended to prevent recurrent ischemic events. The benefit of DAPT post-CABG in patients with stable ischemic heart disease (SIHD) is unknown. The aim of this study was to evaluate the utilization rate of DAPT and associated outcomes in patients with SIHD undergoing CABG via a secondary analysis of Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) trial data. Methods In a post-hoc, nonrandomized analysis from the BARI 2D trial, we compared patients receiving DAPT and aspirin monotherapy within 90 days post-randomization. The primary outcome was the risk adjusted 5-year composite of all-cause mortality, nonfatal myocardial infarction (MI), or stroke. We analyzed patients assigned to prompt CABG treatment arm including both the insulin therapy assignments. Results Of 378 patients, within 90 days post-randomization, 59 (16%) patients received DAPT and 319 (84%) patients received aspirin alone. Cox proportional hazard analysis demonstrated that there was no significant difference in the 5-year composite event of death, MI, and stroke between DAPT and monotherapy cohorts [13 (22.0%) vs. 61 (19.1%); adjusted hazard ratio (HR): 1.06; 95% confidence interval (CI): 0.56 to 2.00; P=0.86]. There also was no significant difference at 1 year in the composite event [6 (10.2%) vs. 30 (9.4%); HR: 1.13; 95% CI: 0.46 to 2.79; P=0.79]. Conclusions The use of DAPT in patients with diabetes post-CABG in this cohort was low. Compared with aspirin monotherapy, no associated differences were observed in cardiovascular outcomes. Larger prospective studies are needed to further elucidate this observation.

Abstract
Background Patients with coronary heart disease (CHD) and survivors of acute coronary syndrome (ACS) are at very high risk for adverse cardiovascular events. Lowering low-density lipoprotein cholesterol (LDL-C) can reduce the risk, with effective lipid-lowering therapy (LLT) readily available; however, dyslipidemia remains prevalent throughout Europe. Design The observational Dyslipidemia International Study II (DYSIS II) aimed to identify unmet treatment needs in adult ACS and CHD patients. Data for the seven participating European countries are presented herein. Methods The study was carried out from December 2012 to November 2014. Use of LLT and attainment of European-guideline-recommended LDL-C targets were assessed. For ACS patients, changes in lipid levels and LLT were evaluated 4 months post-hospitalization. Results Of the 4344 patients enrolled, 2946 were attending a physician visit for the assessment of stable CHD, while 1398 had been hospitalized for an ACS event. In both patient sets, mean LDL-C levels were high (89.5 and 112.5 mg/dl, respectively) and <70 mg/dl target attainment extremely poor. The mean daily statin dosage (normalized to atorvastatin potency) was 27 ± 20 mg for CHD and 22 ± 17 mg for ACS patients. Treatment was intensified slightly for ACS subjects after hospitalization, with the dosage reaching 35 ± 24 mg/day. LDL-C target attainment was higher by the end of the 4-month follow up (30.9% and 41.5% for patients on LLT and without LLT at baseline, respectively; p < 0.05). Conclusion Elevated blood cholesterol levels are highly prevalent across Europe, with low numbers of coronary patients reaching their recommended LDL-C target. While use of LLT is widespread, there is significant scope for intensifying treatment.

[PMID: 30190636 PMCID: PMC6123296 DOI: 10.1016/j.ehj.2018.05.001] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2017] [Accepted: 05/07/2018] [Indexed: 01/19/2023] Open
Abstract
Background Effective management of hyperlipidemia is of utmost importance for prevention of recurring cardiovascular events after an acute coronary syndrome (ACS). Indeed, guidelines recommend a low-density lipoprotein cholesterol (LDL-C) level of <70 mg/dL for such patients. The Dyslipidemia International Study II (DYSIS II) - Egypt was initiated in order to quantify the prevalence and extent of hyperlipidemia in patients presenting with an ACS in Egypt. Methods In this prospective, observational study, we documented patients presenting with an ACS at either of two participating centers in Egypt between November 2013 and September 2014. Individuals were included if they were over 18 years of age, had a full lipid profile available (recorded within 24 h of admission), and had either been taking lipid-lowering therapy (LLT) for ≥3 months at time of enrollment or had not taken LLT. Data regarding lipid levels and LLT were recorded on admission to hospital and at follow-up 4 months later. Results Of the 199 patients hospitalized for an ACS that were enrolled, 147 were on LLT at admission. Mean LDL-C at admission was 127.1 mg/dL, and was not significantly different between users and non-users of LLT. Only 4.0% of patients had an LDL-C level of <70 mg/dL, with the median distance to this target being 61.0 mg/dL. For the patients with LDL-C information available at both admission and follow-up, LDL-C target attainment rose from 2.8% to 5.6%. Most of the LLT-treated patients received statin monotherapy (98.6% at admission and 97.3% at follow-up), with the mean daily statin dose (normalized to atorvastatin) increasing from admission (30 mg/day) to follow-up (42 mg/day). Conclusions DYSIS II revealed alarming LDL-C goal attainment, with none of the patients with follow-up information available reaching the target of LDL-C <70 mg/dL, either at hospital admission or 4 months after their ACS event. Improvements in guideline adherence are urgently needed for reducing the burden of cardiovascular disease in Egypt. Strategies include the effective use of statins at high doses, or combination with other agents recommended by guidelines.

Plaque Characteristics and Ruptured Plaque Location according to Lesion Geometry in Culprit Lesions of ST-Segment Elevation Myocardial Infarction. Korean Circ J 2017; 47:907-917. [PMID: 29171212 PMCID: PMC5711683 DOI: 10.4070/kcj.2017.0108] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2017] [Revised: 08/14/2017] [Accepted: 09/04/2017] [Indexed: 11/19/2022] Open
Abstract
Background and Objectives The correlations between plaque characteristics and plaque rupture location according to segmental lesion analysis have not been well defined. The aim of this study was to assess those characteristics of ST-segment elevation myocardial infarction (STEMI) culprit lesions according to segmental lesion geometry using virtual histology intravascular ultrasound (VH-IVUS). Methods Sixty single discrete lesions found in the left anterior descending (LAD) coronary arteries of 60 patients with STEMI were included. Each lesion was divided into 3 segments based on lumen area (LA) index, calculated by dividing the lesion LA by the reference LA. Results Among the 3 segments, the mid-segment showed the highest proportion of necrotic core (NC; proximal, mid-, and distal segments: 20.9±11.8%, 22.7±11.3%, and 17.5±11.2%, respectively, p=0.044). VH-IVUS-derived thin-cap fibroatheroma (VH-TCFA) was also more frequently found in the mid-segment than in proximal and distal segments (36.7%, 58.3%, and 16.7%, p<0.001). The mid-segment also showed the highest prevalence of plaque rupture (45.0%, 78.3% and 11.7%, p<0.001) and thrombus (61.7%, 95.0%, and 41.7%, p<0.001) compared to proximal or distal segments. When the lesions were divided into 2 groups according to the median value (4.0 mm2) of minimum lumen area (MLA), plaque rupture at the distal segment was observed only in high MLA lesions (23.3% vs. 0.0%, p=0.011). Conclusion Analysis of longitudinal lesion geometry using the LA index can be useful in evaluating plaque vulnerability and the incidence of plaque rupture and thrombus in STEMI patients.

Abstract
BACKGROUND Previous studies reported that reduced TIMI (Thrombolysis in Myocardial Infarction) flow grade before procedure was associated with worse clinical outcomes in patients with ST-segment-elevation myocardial infarction undergoing primary percutaneous coronary intervention. The aim of this study was to identify specific morphological characteristics of the culprit plaque associated with poor TIMI flow grade at baseline in patients with ST-segment-elevation myocardial infarction using both optical coherence tomography and intravascular ultrasound. METHODS AND RESULTS A total of 111 ST-segment-elevation myocardial infarction patients who underwent percutaneous coronary intervention within 24 hours of symptom onset were included. Both optical coherence tomography and intravascular ultrasound were performed after thrombectomy. Patients were divided into 2 groups according to preprocedural TIMI flow grade (TIMI 0-1 [n=82] and TIMI 2-3 [n=29]). Patients with preprocedural TIMI 0 to 1 had a greater lipid arc (P=0.037), a longer lipid length (P=0.021), and a greater lipid index (P=0.007) determined by optical coherence tomography and a larger external elastic membrane cross-sectional area (P=0.030) and plaque plus media cross-sectional area (P=0.030) determined by intravascular ultrasound, compared with patients with preprocedural TIMI 2 to 3. CONCLUSIONS ST-segment-elevation myocardial infarction patients with reduced TIMI flow grade at baseline have greater lipid burden, larger vessel sizes, and larger plaque areas.

Abstract
Abstract
The aim of this study was to demonstrate that the transluminal contrast attenuation gradient (TAG), a new CT imaging-derived marker of functional significance of a coronary stenosis, is directly associated with the vulnerability degree of atheromatous coronary plaques. Material and methods: This is a prospective study on 21 patients with 30 atheromatous plaques in the coronary arteries, who underwent cardiac computed tomography angiography (CCTA) for assessment of coronary plaques. Results: Twelve plaques were classified as vulnerable (40%) and 18 plaques (60%) as non-vulnerable. Plaques associated with a TAG value above 10 HU exhibited in a significantly higher proportion CCTA markers of plaque vulnerability, as compared to plaques in which the attenuation gradient was below 10 HU. TAG values >10 HU were associated with a higher amount of plaque volume (107.4 ± 91.2 mm3 vs. 56.0 ± 37.5 mm3, p = 0.009), necrotic core (32.5 ± 36.9 mm3 vs. 3.1 ± 3.2 mm3, p = 0.0003), and fibro-fatty tissue (17.7 ± 16.3 mm3 vs. 4.0 ± 2.6 mm3, p = 0.0002), as compared to those lesions with TAG values below 10 HU. Linear regression analysis revealed a significant correlation between TAG values and CCTA features of plaque instability: necrotic core (r = −0.73, p <0.0001), fibrofatty tissue (r = −0.63, p = 0.0002), and plaque volume (r = −0.48, p = 0.006). Conclusions: In patients with coronary artery disease, contrast attenuation gradient along the coronary plaques, determined by CCTA, correlates with CT markers of plaque vulnerability. Vulnerable coronary plaques are associated with a higher functional significance than the stable ones with a similar anatomic profile.

Determinants of slow flow following stent implantation in intravascular ultrasound-guided primary percutaneous coronary intervention. Heart Vessels 2017; 33:226-238. [PMID: 28887713 DOI: 10.1007/s00380-017-1050-z] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2017] [Accepted: 09/06/2017] [Indexed: 12/13/2022]
Abstract
Slow flow is a serious complication in primary percutaneous coronary intervention (PCI) and is associated with poor clinical outcomes. Intravascular ultrasound (IVUS)-guided PCI may improve clinical outcomes after drug-eluting stent implantation. The purpose of this study was to seek the factors of slow flow following stent implantation, including factors related to IVUS-guided primary PCI. The study population consisted of 339 ST-elevation myocardial infarction patients, who underwent stent deployment with IVUS. During PCI, 56 patients (16.5%) had transient or permanent slow flow. Multivariate logistic regression analysis showed age (OR 1.04, 95% CI 1.01-1.07, P = 0.01), low attenuation plaque on IVUS (OR 3.38, 95% CI 1.70-6.72, P = 0.001), initial Thrombolysis In Myocardial Infarction (TIMI) flow grade 2 (vs. TIMI 0: OR 0.44, 95% CI 0.20-0.99, P = 0.046), and the ratio of stent diameter to vessel diameter (per 0.1 increase: OR 2.63, 95% CI 1.84-3.77, P < 0.001) were significantly associated with slow flow. A ratio of stent diameter to vessel diameter of 0.71 had an 80.4% sensitivity and 56.9% specificity to predict slow flow. There was no significant difference in ischemic-driven target vessel revascularization between the modest stent expansion (ratio of stent diameter to vessel diameter <0.71) and aggressive stent expansion (ratio of stent diameter to vessel diameter ≥0.71) strategies. Unlike other variables, the ratio of stent diameter to vessel diameter was the only modifiable factor. The modest stent expansion strategy should be considered to prevent slow flow following stent implantation in IVUS-guided primary PCI.

Abstract
AIMS Our aim was to compare stenosis severity and plaque content between STEMI culprit lesions with intact fibrous cap (IFC) and those with plaque rupture (PR) in a prospective study. METHODS AND RESULTS We evaluated 93 patients undergoing OCT and thrombectomy as part of a prospective substudy of the TOTAL (ThrOmbecTomy versus PCI ALone) trial. Culprit lesion morphology was assessable by OCT in 70/93 (75.3%). IFC was found in 31 (44.3%), PR in 34 (48.6%) and calcified nodule in five (7.1%) patients. Following thrombectomy, OCT demonstrated similar lumen area stenosis in IFC (79.3%) and PR (79.6%) (p=0.88). Lumen area stenosis <50% was observed in none of the patients with PR and in one patient with IFC. IFC had fewer quadrants with lipid plaque as compared to PR (28.16±15.02 vs. 39.12±14.23, p=0.004). However, in both lesion types, lipid was the predominant plaque type (83.9 vs. 63.7% of diseased quadrants). CONCLUSIONS In a prospective study of STEMI patients treated with thrombectomy, mild residual stenoses were uncommon in IFC lesions. Although lipid content was lower than in PR lesions, lipid composed the majority of the diseased segments in IFC.

Abstract
BACKGROUND Increasing coronary lesion calcification is thought to be associated with adverse percutaneous coronary intervention (PCI) and clinical outcomes. We investigated the effects of calcium burden on culprit lesion morphology and clinical events after intravascular ultrasound (IVUS)-guided PCI in the ADAPT-DES study. METHODS ADAPT-DES was a prospective, multicenter registry of 8582 consecutive patients undergoing successful PCI using DES. A pre-specified virtual histology (VH)-IVUS substudy of 638 culprit lesions (638 patients) had both pre- and post-PCI VH-IVUS. We divided lesions into tertiles according to pre-PCI percent dense calcium volume (DCV%=dense calcium/plaque volume×100). RESULTS Compared with low and intermediate DCV% tertiles, patients in the high DCV% tertile had the largest arc of superficial calcium, highest percentage of necrotic core volume, and smallest remodeling index; they were also more likely to have advanced lesion morphology such as attenuated plaque and VH thin-cap fibroatheromas. In the high DCV% tertile IVUS guidance was associated with a minimum stent area that was smaller than tertiles with less calcium (p=0.01), but acceptable range, and similar stent expansion (73.8±16.8% vs. 74.0±19.2% vs. 72.4±17.3%, p=0.62) after more frequent use of rotational atherectomy and higher maximum inflation pressure. There was no significant association between pre-PCI DCV% and 2-year target lesion revascularization or major adverse cardiac events (cardiac death, myocardial infarction, or stent thrombosis). CONCLUSIONS Increasing coronary artery calcification burden was associated with more advanced, complex VH-IVUS lesion morphology, but not with adverse clinical outcomes, perhaps due to more aggressive PCI techniques that optimized stent expansion.

Abstract
Abstract
The aim of this preliminary study was to assess the effectiveness of transluminal contrast attenuation gradient (TAG) determined by computed tomographic angiography (CTA), for the evaluation of the functional significance of coronary artery stenoses in patients with acute coronary syndromes produced by vulnerable coronary plaques, and to demonstrate the correlation between this new parameter and the vulnerability markers of the culprit lesions.
Material and methods: This is a preliminary pilot study on 10 patients with acute coronary syndromes – unstable angina type, who underwent CTA for the assessment of coronary lesions, followed by invasive angiography and the determination of fractional flow reserve (FFR) prior to a revascularization procedure. Patients were divided into 2 groups, according to their FFR values: Group 1 consisted of 6 patients with an FFR value <0.8 (functionally significant lesion), and Group 2 consisted of 4 patients who presented an FFR value >0.8 (functionally non-significant lesion).
Results: FFR values were 0.64 ± 0.07, 95% CI: 0.5–0.7 in Group 1, and 0.86 ± 0.05, 95% CI: 0.7–0.9 in Group 2. Plaques associated with an FFR<0.8 presented a higher amount of plaque volume (192.7 ± 199.7 mm3 vs. 42.1 ± 27.3 mm3, p = 0.1), necrotic core (66.7 ± 72.9 mm3 vs. 10.0 ± 9.3 mm3, p = 0.1), and fibro-fatty tissue (29.7 ± 37.4 mm3 vs. 6.2 ± 3.8 mm3, p = 0.2). At the same time, TAG significantly correlated with the presence of a functionally significant lesion. Coronary lesions associated with low FFR presented significantly higher values of TAG along the plaque as compared with lesions with FFR values >0.8 (TAG values 22.1 ± 5.8 HU vs. 11.7 ± 2.5 HU, p = 0.01). Linear regression identified a significant correlation between TAG and FFR values as a measure of functional significance of the lesion (r = 0.7, p = 0.01).
Conclusions: Contrast attenuation gradient along the culprit lesion, determined by CTA, correlates with the FFR values and with CT markers of plaque vulnerability, indicating that the presence of vulnerability features inside a coronary plaque could increase the functional significance of a coronary lesion.

Abstract
Prediction of coronary events remains elusive. Carotid atherosclerosis may be a surrogate for coronary risk, as carotid and coronary diseases occur simultaneously - albeit at times with a weak association - depending on clinical presentation. We investigated carotid and coronary atherosclerosis in men with new-onset unstable coronary artery disease (CAD) presenting with acute ST-segment elevation myocardial infarction (STEMI) vs. long-standing severe chronic stable angina (CSA). Bilateral carotid artery and 3-vessel coronary artery atherosclerosis burdens were measured within 1 month, respectively, by 3D-volumetric carotid magnetic resonance imaging and coronary angiography-derived modified CASS-50 score. Men with STEMI (n = 50) and long-standing CSA (n = 50), matched for age, were enrolled (58.6 ± 8.8 years). All of them had carotid atherosclerosis. Atherosclerosis burden was greater in the carotid arteries of STEMI vs. CSA (wall volume: 196.2 ± 44.4 vs. 169.2 ± 38.0 mm3/4 mm, p = 0.002), but greater in the coronary arteries of CSA vs. STEMI (modified CASS-50 score: 3 vs. 1, p < 0.0001). Normalized wall index (NWI) of internal carotid was associated with modified CASS-50 score in STEMI (ρ = 0.40, p = 0.022) and in CSA (ρ = -0.39, p = 0.031). Carotid atherosclerosis was observed in all CAD patients, and atherosclerosis burden in carotid and in coronary arteries varied according to clinical presentation.

Prognostic impact of alkaline phosphatase measured at time of presentation in patients undergoing primary percutaneous coronary intervention for ST-segment elevation myocardial infarction. PLoS One 2017; 12:e0171914.

Abstract
Background Serum alkaline phosphatase (ALP) has been shown to be a prognostic factor in several subgroups of patients due to its promotion of vascular calcification. However, the prognostic impact of serum ALP level in ST-segment elevation myocardial infarction (STEMI) patients with a relatively low calcification burden has not been determined. We aimed to investigate the association of ALP level measured at time of presentation on clinical outcomes in patients with STEMI requiring primary percutaneous coronary intervention (PCI). Methods A total of 1178 patients with STEMI undergoing primary PCI between 2007 and 2014 were retrospectively enrolled from the INTERSTELLAR registry and classified into tertiles by ALP level (<64, 65–82, or >83 IU/L). The primary study outcome was a major adverse cardiac or cerebrovascular event (MACCE), defined as the composite of all-cause death, non-fatal myocardial infarction, non-fatal stroke, and ischemia-driven revascularization. Results Median follow-up duration was 25 months (interquartile range, 10–39 months). The incidence of MACCE significantly increased as ALP level increased, that is, for the <64, 65–82, and >83 IU/L tertiles incidences were 8.7%, 11.7%, and 15.7%, respectively; p for trend = 0.003). After adjustment for potential confounders, the adjusted hazard ratios for MACCE in the middle and highest tertiles were 1.69 (95% CI 1.01–2.81) and 2.46 (95% CI 1.48–4.09), respectively, as compared with the lowest ALP tertile. Conclusions Elevated ALP level at presentation, but within the higher limit of normal, was found to be independently associated with higher risk of MACCE after primary PCI in patients with STEMI.

Relation Between Renal Function and Coronary Plaque Morphology (from the Assessment of Dual Antiplatelet Therapy With Drug-Eluting Stents Virtual Histology-Intravascular Ultrasound Substudy). Am J Cardiol 2017; 119:217-224.

Abstract
We sought to examine the relation between various degrees of renal function and coronary plaque morphology by grayscale and virtual histology intravascular ultrasound (IVUS). ADAPT-DES was a prospective, multicenter registry of 8,582 consecutive patients treated using coronary drug-eluting stents with a prespecified grayscale and virtual histology-IVUS substudy. A lesion-level analysis of study participants was performed by comparing IVUS parameters of culprit and nonculprit lesions across tertiles of estimated creatinine clearance (CrCl). Preintervention IVUS imaging of 762 patients identified 898 culprit and 752 nonculprit native coronary artery lesions. Patients in the lowest CrCl tertile were older, more often women, and more often presented with stable angina. Compared with the middle and upper tertiles, the lowest tertile was significantly associated with culprit lesion smaller mean external elastic membrane cross-sectional area (12.9 vs 14.2 mm3/mm vs 14.9 mm3/mm, p <0.0001), smaller mean lumen cross-sectional area (5.5 mm3/mm vs 5.8 mm3/mm vs 6.1 mm3/mm, p = 0.002), and more dense calcium volume (11.5% vs 10.2% vs 9.7%, p = 0.02). Similar trends were found in the nonculprit lesions. Plaque rupture was least common in patients in the lowest tertile. On multivariable analysis, independent predictors of greater dense calcium volume were lower CrCl, hyperlipidemia, female gender, and presentation without ST-segment elevation myocardial infarction. In conclusion, in the present large-scale IVUS study diminishing renal function was associated with increased coronary calcification and decreased coronary vessel and lumen sizes, with a graded response according to the reduction in CrCl. In addition, these patients were more likely to present with stable angina versus patients with normal renal function who were more likely to present with an acute coronary syndrome.

Abstract
Background Helicobacter pylori infection and interleukin-1 polymorphisms are associated with an increased risk of gastric cancer. We examined the prevalence of Helicobacter pylori seropositivity and interleukin-1 polymorphisms between ST-segment elevation myocardial infarction and non-ST-segment elevation acute coronary syndrome patients. Methods We recruited consecutive acute coronary syndrome patients, and 101 non-ST-segment elevation acute coronary syndrome patients and 103 ST-segment elevation myocardial infarction patients were enrolled. Interleukin-1 polymorphism analyses were performed for single nucleotide polymorphism in interleukin-1 beta-511 and the variable number of tandem repeats polymorphism in the interleukin-1 receptor antagonist by polymerase chain reaction. Immunoglobulin G antibodies against Helicobacter pylori and high sensitivity C-reactive protein were also measured. Results The rates of the simultaneous presence of interleukin-1 polymorphisms and Helicobacter pylori-seropositivity between non-ST-segment elevation acute coronary syndrome and ST-segment elevation myocardial infarction groups were 25.7% and 42.7%, respectively (P = 0.012). Helicobacter pylori-seropositive subjects with interleukin-1 polymorphisms showed significantly higher levels of high sensitivity C-reactive protein (0.04–0.12 vs. 0.02–0.05; P<0.001). Multivariate logistic regression analysis revealed that the carriage of Helicobacter pylori-seropositivity and interleukin-1 polymorphisms was significantly associated with ST-segment elevation myocardial infarction (odds ratio, 2.32; 95% confidence interval, 1.23–4.37; P = 0.009). The C-statistic of conventional risk factors was 0.68 (P<0.001) and that including Helicobacter pylori-seropositivity and interleukin-1 polymorphisms was 0.70 (P<0.001); continuous net reclassification improvement was 34% (P = 0.0094) and integrated discrimination improvement was 3.0% (P = 0.014). Conclusions The coincidence of Helicobacter pylori-seropositivity and interleukin-1 polymorphisms was significantly associated with higher levels of high sensitivity C-reactive protein and the increased risk of ST-segment elevation myocardial infarction.

Abstract
Cardiac fibrosis evolves from the cardiac hypertrophic state. In this respect, estrogen and estrogen receptor beta (ERβ) inhibit the effects of cardiac hypertrophic peptides that also stimulate fibrosis. Here we determine details of the anti-fibrotic functions of ERβ. In acutely isolated rat cardiac fibroblasts. E2 or a specific ERβ agonist (βLGND2) blocked angiotensin II (AngII) signaling to fibrosis. This resulted from ERβ activating protein kinase A and AMP kinase, inhibiting both AngII de-phosphorylation of RhoA and the resulting stimulation of Rho kinase. Inhibition of Rho kinase from ERβ signaling resulted in marked decrease of TGFβ expression, connective tissue growth factor production and function, matrix metalloproteinases 2 and 9 expression and activity, and the conversion of fibroblasts to myofibroblasts. Production of collagens I and III were also significantly decreased. Several important aspects were corroborated in-vivo from βLGND2-treated mice that underwent AngII-induced cardiac hypertrophy. Thus, ERβ in cardiac fibroblasts prevents key aspects of cardiac fibrosis development.

Abstract
OBJECTIVES This study sought to investigate the impact of longitudinal lesion geometry on the location of plaque rupture and clinical presentation and its mechanism. BACKGROUND The relationships among lesion geometry, external hemodynamic forces acting on the plaque, location of plaque rupture, and clinical presentation have not been comprehensively investigated. METHODS This study enrolled 125 patients with plaque rupture documented by intravascular ultrasound. Longitudinal locations of plaque rupture were identified and categorized by intravascular ultrasound. Patients' clinical presentations and TIMI (Thrombolysis In Myocardial Infarction) flow grade in an initial angiogram were compared according to the location of plaque rupture. Longitudinal lesion asymmetry was quantitatively assessed by the luminal radius change over the segment length (radius gradient [RG]). Lesions with a steeper radius change in the upstream segment compared with the downstream segment (RGupstream > RGdownstream) were defined as upstream-dominant lesions. RESULTS On the basis of the site of maximum rupture aperture, 56.0%, 16.0%, and 28.0% of the patients had upstream, minimal lumen area, and downstream rupture, respectively. Patients with upstream rupture more frequently presented with ST-segment elevation myocardial infarction (45.7%, 40.0%, 22.9%; p = 0.030) and with TIMI flow grade <3 (32.9%, 20.0%, 17.1%; p = 0.042). According to the ratio of upstream and downstream RG, 69.5% of lesions were classified as upstream-dominant lesions, and 30.5% were classified as downstream-dominant lesions. Among the 66 upstream-dominant lesions, 65 cases (98.5%) had upstream rupture, and the RG ratio (RGupstream/RGdownstream) was an independent predictor of upstream rupture (odds ratio: 1.481; 95% confidence interval: 1.035 to 2.120; p = 0.032). Upstream-dominant lesions more frequently manifested with ST-segment elevation myocardial infarction than did downstream-dominant lesions (48.5% vs. 24.1%; p = 0.026). CONCLUSIONS Both clinical presentation and degree of flow limitation were associated with the location of plaque rupture. Longitudinal lesion asymmetry assessed by RG, which can affect regional distribution of hemodynamic stress, was associated with the location of rupture and with clinical presentation.

Abstract
BACKGROUND A relevant proportion of patients with acute ischemic stroke (AIS) have elevated levels of cardiac troponins (cTn). However, the frequency of coronary ischemia as the cause of elevated cTn is unknown. The aim of our study was to analyze coronary vessel status in AIS patients with elevated cTn compared with patients presenting with non-ST-segment-elevation acute coronary syndrome (NSTE-ACS). METHODS AND RESULTS Among 2123 consecutive patients with AIS prospectively screened at 2 tertiary hospitals, 13.7% had cTn elevation (>50 ng/L). According to a prespecified sample size estimation, 29 patients with AIS (median age, 76 years [first-third quartiles, 70-82 years]; 52% male) underwent conventional coronary angiography and were compared with age- and sex-matched patients with NSTE-ACS. The primary end point was presence of coronary culprit lesions on coronary angiograms as analyzed by independent interventional cardiologists blinded for clinical data. Median cTn on presentation did not differ between patients with AIS or NSTE-ACS (95 versus 94 ng/L; P=0.70). Compared with patients with NSTE-ACS, patients with AIS were less likely to have coronary culprit lesions (7 of 29 versus 23 of 29; P<0.001) or any obstructive coronary artery disease (15 of 29 versus 25 of 29; P=0.02; median number of vessels with >50% stenosis, 1 [first-third quartiles, 0-2] versus 2 [first-third quartiles, 1-3]; P<0.01). CONCLUSIONS Coronary culprit lesions are significantly less frequent in AIS patients compared with age- and sex-matched patients with NSTE-ACS despite similar baseline cTn levels. Half of all AIS patients had no angiographic evidence of coronary artery disease. Further studies are needed to clinically identify the minority of patients with AIS and angiographic evidence of a culprit lesion. CLINICAL TRIAL REGISTRATION URL: http://www.clinicaltrials.gov.
