Abstract
The aim of this study is to predict acute coronary syndrome (ACS) requiring revascularization in those patients presenting early-stage angina-like symptom using machine learning algorithms. We obtained data from 2344 ACS patients, who required revascularization and from 3538 non-ACS patients. We analyzed 20 features that are relevant to ACS using standard algorithms, support vector machines and linear discriminant analysis. Based on feature pattern and filter characteristics, we analyzed and extracted a strong prediction function out of the 20 selected features. The obtained prediction functions are relevant showing the area under curve of 0.860 for the prediction of ACS that requiring revascularization. Some features are missing in many data though they are considered to be very informative; it turned out that omitting those features from the input and using more data without those features for training improves the prediction accuracy. Additionally, from the investigation using the receiver operating characteristic curves, a reliable prediction of 2.60% of non-ACS patients could be made with a specificity of 1.0. For those 2.60% non-ACS patients, we can consider the recommendation of medical treatment without risking misdiagnosis of the patients requiring revascularization. We investigated prediction algorithm to select ACS patients requiring revascularization and non-ACS patients presenting angina-like symptoms at an early stage. In the future, a large cohort study is necessary to increase the prediction accuracy and confirm the possibility of safely discriminating the non-ACS patients from the ACS patients with confidence.

Abstract
OBJECTIVE To evaluate the efficacy and safety of standard term (12 months) or long term (>12 months) dual antiplatelet therapy (DAPT) versus short term (<6 months) DAPT after percutaneous coronary intervention (PCI) with drug-eluting stent (DES). DESIGN Systematic review and network meta-analysis. DATA SOURCES Relevant studies published between June 1983 and April 2018 from Medline, Embase, Cochrane Library for clinical trials, PubMed, Web of Science, ClinicalTrials.gov, and Clinicaltrialsregister.eu. REVIEW METHODS Randomised controlled trials comparing two of the three durations of DAPT (short term, standard term, and long term) after PCI with DES were included. The primary study outcomes were cardiac or non-cardiac death, all cause mortality, myocardial infarction, stent thrombosis, and all bleeding events. RESULTS 17 studies (n=46 864) were included. Compared with short term DAPT, network meta-analysis showed that long term DAPT resulted in higher rates of major bleeding (odds ratio 1.78, 95% confidence interval 1.27 to 2.49) and non-cardiac death (1.63, 1.03 to 2.59); standard term DAPT was associated with higher rates of any bleeding (1.39, 1.01 to 1.92). No noticeable difference was observed in other primary endpoints. The sensitivity analysis revealed that the risks of non-cardiac death and bleeding were further increased for ≥18 months of DAPT compared with short term or standard term DAPT. In the subgroup analysis, long term DAPT led to higher all cause mortality than short term DAPT in patients implanted with newer-generation DES (1.99, 1.04 to 3.81); short term DAPT presented similar efficacy and safety to standard term DAPT with acute coronary syndrome (ACS) presentation and newer-generation DES placement. The heterogeneity of pooled trials was low, providing more confidence in the interpretation of results. CONCLUSIONS In patients with all clinical presentations, compared with short term DAPT (clopidogrel), long term DAPT led to higher rates of major bleeding and non-cardiac death, and standard term DAPT was associated with an increased risk of any bleeding. For patients with ACS, short term DAPT presented similar efficacy and safety with standard term DAPT. For patients implanted with newer-generation DES, long term DAPT resulted in more all cause mortality than short term DAPT. Although the optimal duration of DAPT should take personal ischaemic and bleeding risks into account, this study suggested short term DAPT could be considered for most patients after PCI with DES, combining evidence from both direct and indirect comparisons.

Coronary perforation complicating percutaneous coronary intervention in patients presenting with an acute coronary syndrome: An analysis of 1013 perforation cases from the British Cardiovascular Intervention Society database. Int J Cardiol 2019; 299:37-42.

Abstract
BACKGROUND The evidence base for coronary perforation occurring during percutaneous coronary intervention in patients presenting with an acute coronary syndrome (ACS-PCI) is limited and the specific role of acute pharmacology in its clinical presentation unclear. METHODS AND RESULTS Using the BCIS PCI database, data were analysed on all ACS-PCI procedures performed in England and Wales between 2007 and 2014. Multiple regressions were used to identify predictors of coronary perforation and its association with outcomes. Propensity score matching was used to evaluate the association between differing P2Y12 inhibitors or glycoprotein inhibitors (GPI) and CP. During 270,329 ACS-PCI procedures, 1013 coronary perforations were recorded (0.37%) with a stable annual incidence. In multiple regression analysis, covariates associated with increased frequency of coronary perforation included age, female gender, CTO intervention, number and length of stents used, and rotational atherectomy use, whilst differing P2Y12 inhibitors were not predictive. Using propensity score matching, use of a GPI was independently associated with tamponade (OR 1.50, [1.08-2.06], p = 0.014). The adjusted odds ratios for all clinical outcomes were adversely affected by coronary perforation. CONCLUSIONS Coronary perforation is an infrequent event during ACS-PCI but is closely associated with adverse clinical outcomes. GPI use was associated with higher rates of tamponade.

Abstract
INTRODUCTION 'Real world' bleeding in patients exposed to different regimens of dual antiplatelet therapy (DAPT) and triple therapy (TT, DAPT plus an anticoagulant) have a clinical and economic impact but have not been previously quantified. METHODS AND ANALYSIS We will use linked Clinical Practice Research Datalink (CPRD) and Hospital Episode Statistics (HES) data to assemble populations eligible for three 'target trials' in patient groups: percutaneous coronary intervention (PCI); coronary artery bypass grafting (CABG); conservatively managed (medication only) acute coronary syndrome (ACS). Patients ≥18 years old will be eligible if, in CPRD records, they have: ≥1 year of data before the index event; no prescription for DAPT or anticoagulants in the preceding 3 months; a prescription for aspirin or DAPT within 2 months after discharge from the index event. The primary outcome will be any bleeding event (CPRD or HES) up to 12 months after the index event. We will estimate adjusted HR for time to first bleeding event comparing: aspirin and clopidogrel (reference) versus aspirin and prasugrel or aspirin and ticagrelor after PCI; and aspirin (reference) versus aspirin and clopidogrel after CABG and ACS. We will describe rates of bleeding in patients prescribed TT (DAPT plus an anticoagulant). Potential confounders will be identified systematically using literature review, semistructured interviews with clinicians and a short survey of clinicians. We will conduct sensitivity analyses addressing the robustness of results to the study's main limitation-that we will not be able to identify the intervention group for patients whose bleeding event occurs before a DAPT prescription in CPRD. ETHICS AND DISSEMINATION This protocol was approved by the Independent Scientific Advisory Committee for the UK Medicines and Healthcare Products Regulatory Agency Database Research (protocol 16_126R) and the South West Cornwall and Plymouth Research Ethics Committee (17/SW/0092). The findings will be presented in peer-reviewed journals, lay summaries and briefing papers to commissioners/other stakeholders. TRIAL REGISTRATION NUMBER 76607611; Pre-results.

Abstract
Treatment of acute coronary syndromes secondary to septic coronary valvular embolism in endocarditis patients remains unclear. Several revascularization strategies have been described, including thromboaspiration, stent implantation, balloon angioplasty, and surgical intervention. We herein present an illustration of an atypical case of an acute coronary syndrome related to a coronary bifurcation occlusion due to a septic embolism in a patient presenting with infective endocarditis. We also summarized previous similar cases and their management.

Abstract
OBJECTIVES We evaluated the efficacy of low-dose (LD) radiation (≤7.5 frames/second [f/s]) compared with standard-dose (SD) radiation (≥10 f/s) in cardiac catheterization (CC) and percutaneous coronary intervention (PCI). Patients undergoing CC with LD vs SD radiation have not been previously studied. METHODS We performed an observational study of 452 consecutive patients (61 ± 12 years) who had coronary angiography or PCI from September 2016 to September 2017. Patients were divided into an LD radiation group (n = 136) consisting of 0.5 f/s and 1 f/s (n = 73), 4 f/s (n = 40), or 7.5 f/s fluoroscopy (n = 23) with 7.5 f/s cine angiography vs an SD group (n = 316) consisting of 10 f/s (n = 250), 15 f/s (n = 64), or 30 f/s fluoroscopy (n = 2) and 10-30 f/s cine angiography. Primary endpoints included air kerma, dose area product (DAP), fluoroscopy time, and contrast use. RESULTS Compared with SD radiation, LD radiation was associated with a significant reduction in air kerma (100.70 mGy [IQR, 46.42-233.35 mGy] vs 660.96 mGy [IQR, 362.78-1373.65 mGy]; P<.001), DAP (723.60 μGy•m² [IQR, 313.09-2328.22 μGy•m²] vs 5203.40 μGy•m² [IQR, 2743.55-10064.71 μGy•m²]; P<.001), and contrast use (100 mL [IQR, 60-150 mL] vs 115 mL [IQR, 80-180 mL]; P<.03). No difference in fluoroscopy time was noted (13.33 min [IQR, 6.93-25.55 min] vs 12.75 min [IQR, 7.75-22.55 min]; P=.95). CONCLUSIONS LD radiation in CC was efficacious, with significant radiation reduction and without an increase in fluoroscopy time or contrast utilization. All patients underwent successful LD radiation catheterization without conversion to SD.

Abstract
The platelet aggregation inhibitor ticagrelor, a P2Y12 receptor antagonist, is widely used after angioplasty in patients with acute coronary syndrome. Clinical trial data have shown that it is well tolerated by most patients. We present the case of a 62-year-old woman whose ticagrelor-related asymptomatic and persistent sinus pauses after angioplasty resolved when ticagrelor was replaced with prasugrel.

Abstract
BACKGROUND Smoking cessation is important to prevent recurrence of acute coronary syndrome (ACS), but even in patients with ACS, smoking is hard to quit. OBJECTIVES This study hypothesized that aversive advice during the percutaneous coronary intervention (PCI) procedure works effectively to promote smoking cessation in patients with ACS. METHODS This study was conducted as a prospective, single-blinded, randomized controlled trial. A total of 66 patients were randomly assigned to an aversive advice group or a control group and instructed to visit the outpatient clinic 1, 4, and 24 weeks after discharge. In the aversive advice group, a physician who did not participate in the patient follow-up said the following 3 sentences to the patients during the PCI procedure: "Smoking caused your chest pain"; "If you do not stop smoking right now, this pain will come again"; and "The next time you feel this pain you will probably die." All patients received usual advice on the importance of quitting smoking. RESULTS At 24 weeks after discharge, the smoking cessation rate was higher in the aversive advice group than in the control group. In a multivariable logistic regression analysis, after adjustment for age, smoking quantity, alcohol consumption, and disease severity, the result was maintained (odds ratio = 4.47, 95% confidence interval: 1.50 to 13.34). CONCLUSIONS Aversive advice during a PCI procedure is effective at smoking cessation in patients with ACS. A physician's attention and involvement during the PCI procedure improves the rate of smoking cessation in patients with ACS.

Abstract
We reviewed 54,044 adult cases of cardiogenic shock (CS) accompanying acute coronary syndrome from the 2005 to 2014 Nationwide Inpatient Sample. We evaluated outcomes among patients who were nonobese, obese (body mass index 30.0 to 39.9 kg/m2) and extremely-obese (body mass index ≥40 kg/m2). A multivariate analysis was performed to assess their impact on in-hospital mortality. There were 3,602 (6.6%) and 1,610 (2.9%) admissions among patients who were obese and extremely-obese. Those obese and extremely-obese were younger compared with the nonobese (62.7 vs 61.2 vs 68.8 years, respectively; p <0.01) but had significantly greater comorbidity burden. CS patients who were not-obese were most likely to have an associated ST elevation myocardial infarction, compared with the obese and extremely-obese (67.7% vs 65.9% vs 60.7%; p <0.01). Compared to the nonobese, patients who were obese had higher rates of percutaneous coronary intervention (55.8% vs 51.5%; p <0.01) and coronary artery bypass grafting (24.0% vs 16.0%; p <0.01) whereas those extremely-obese had higher coronary artery bypass grafting rates (23.9% vs 16.0%; p <0.01) but similar percutaneous coronary intervention rates (51.1% vs 51.5%; p = 0.74). Short-term mechanical support use was lowest among the nonobese followed by the extremely-obese and obese. Adjusted analysis revealed that obesity predicted less (adjusted odd ratio 0.82, 95% confidence interval 0.76 to 0.90) and extreme-obesity predicted higher in-hospital mortality (adjusted odds ratio 1.17, 95% confidence interval 1.05 to 1.32) compared with the nonobese. In conclusion, obesity and extreme-obesity are associated with greater comorbidity burden among ACS related CS admissions. Obesity predicted less in-hospital mortality, whereas extreme obesity was associated with elevated in-hospital mortality.

Abstract
Homozygous familial hypercholesterolemia developed into severe cardiovascular consequences early. Untreated HoFH usually cannot survive over 30 years old. Acute coronary syndrome(ACS) caused by plaque rupture is one of the main causes of death in HoFH. As the highest resolution intravascular imaging technique, optical coherence tomography(OCT) can clearly show the thickness and structural characteristics of atherosclerotic plaque caps. In this study, a Chinese male HoFH received percutaneous coronary intervention for unstable angina. After analyzed his genetic and follow-up data, OCT was performed during interventional therapy. Multiple lipid rich plaques accompanied with inflammatory cell infiltration and a thin-cap fibroatheroma(TCFA) were noted, which reflected the vulnerability of plaques. The utility of OCT had certain guiding significance for strategy of interventional therapy and the long-term drug management. And this case suggested that it was important to undergo OCT examination for patients with HoFH who required percutaneous coronary intervention.

Abstract
OBJECTIVES Successful treatment of acute coronary syndrome (ACS) relies on its rapid recognition. It is unclear whether the accepted presentation of chest pain applies to different ethnic groups. We thus examined potential ethnic variations in ACS symptoms and clinical care outcomes in white, South Asian and Chinese patients. DESIGN Cross-sectional survey. SETTING Participants were hospitalised at 1 of 12 Canadian centres across four provinces. PARTICIPANTS 1334 patients with ACS (630 white; 488 South Asian; 216 Chinese). MAIN OUTCOME MEASURES ACS presentation symptoms (classic/typical midsternal pain/discomfort with or without radiation to the left neck, shoulder or arm) were assessed by self-report. Clinical care outcomes (time to emergency room [ER] presentation, cardiac catheterisation; receipt of cardiac catheterisation, percutaneous coronary intervention [PCI] or coronary artery bypass grafting [CABG]) were obtained by health record audit. RESULTS The mean age of the sample was 62 years and 30% had ST-elevation myocardial infarction (STEMI). The most common presenting symptom was midsternal pain/discomfort of any intensity regardless of ethnic status. Yet, a substantial proportion of patients reported atypical symptoms (33% white, 19% South Asian, 20% Chinese; p<0.006). After adjustment for age, sex, education, current smoking, extent of coronary artery disease, presence of diabetes or chronic kidney disease and STEMI vs non-STEMI/unstable angina, South Asians were more likely to present with at least moderate intensity midsternal pain/discomfort (adjusted OR [AOR] 1.44; 95% CI 1.05 to 1.98), whereas Chinese were less likely to present with radiating symptoms (AOR 0.53; 95% CI 0.38 to 0.74) compared with whites. South Asians with atypical pain (relative to those with midsternal pain/discomfort) took significantly longer to present to the ER (p=0.037), and were less likely to receive PCI (p=0.008) or CABG (p=0.041). CONCLUSIONS Atypical presentations were associated with greater delays in arrival to the emergency department and reduced invasive cardiovascular care in South Asians.

Abstract
INTRODUCTION Percutaneous coronary interventions (PCIs) and coronary angiography are two of the treatments administered to acute coronary syndrome (ACS) patients. However, whether and how patients' health-related quality of life (HRQoL) influences treatment decisions and subsequent risk benefit analyses is unclear. In this study, we will review the available evidence on the impact of patients' HRQoL on physicians' prescribing or treatment decisions and on the estimation of mortality and bleeding risk in ACS patients. METHODS AND ANALYSIS We will undertake a systematic review of all quantitative and qualitative studies. The search will include studies that describe the impact of HRQoL on prescribing PCIs or angiography, and impact of HRQoL on perceived risks in terms of mortality and bleeding events. We will conduct an initial search on Google scholar and MEDLINE to build the searching terms followed by a full search strategy using all identified keywords and index terms across the five databases, namely MEDLINE, PubMed, CINAHL, SCOPUS and Web of Sciences. We will use the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for protocol guidelines to present the protocol. Only English language articles will be included for the review. We will use a standardised Joanna Briggs Institute data extraction tool to synthesise the information extracted from the selected studies into themes with summary findings presented in a table. ETHICS AND DISSEMINATION We will not require a formal ethical approval as we will not be collecting primary data. Review findings will be disseminated through a peer-reviewed publication, workshops, conference presentations and a media release. PROSPERO REGISTRATION NUMBER CRD42018108438.

Abstract
We sought to examine if the risk conferred by high on-treatment platelet reactivity (HPR) varies based upon clinical presentation. We examined the relation between HPR (P2Y12 reaction units >208) and adverse ischemic and bleeding events among patients with and without acute coronary syndromes (ACS) from ADAPT-DES; 51.7% of patients had ACS. After clopidogrel loading, ACS patients had higher P2Y12 reaction units and a greater prevalence of HPR based on VerifyNow P2Y12 assay. Of 92 definite or probable stent thrombosis (ST) events at 2 years, 65.2% occurred among patients with ACS. HPR was independently associated with ST in ACS patients (adjusted hazard ratio 2.29, 95% confidence interval 1.32 to 3.98) but not with clinically relevant bleeding. Although no statistical interactions between ACS status and these associations were observed, non-ACS patients exhibited an attenuated association between HPR and ST, and an inverse association between HPR and clinically relevant bleeding. HPR was similarly associated with myocardial infarction, but not with overall mortality in ACS and non-ACS patients. In conclusion, the majority of ST events in the 2 years after drug-eluting stent placement occurred in ACS patients; HPR was strongly associated with ST in these patients. These data support current recommendations for using more potent antiplatelet therapies in ACS patients.

CHA2DS2-VASc Score as an Independent Predictor of Suboptimal Reperfusion and Short-Term Mortality after Primary PCI in Patients with Acute ST Segment Elevation Myocardial Infarction. ACTA ACUST UNITED AC 2019; 55:medicina55020035. [PMID: 30717292 PMCID: PMC6409514 DOI: 10.3390/medicina55020035] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2019] [Revised: 01/18/2019] [Accepted: 01/22/2019] [Indexed: 01/09/2023]
Abstract
Background and objectives: We aimed to demonstrate the clinical utility of CHA2DS2-VASc score in risk assessment of patients with STEMI regarding adverse clinical outcomes particularly no-reflow phenomenon. Materials and Methods: We designed a retrospective cohort study using the data of Tehran Heart Center registry for acute coronary syndrome. The study included 1331 consecutive patients with STEMI who underwent primary angioplasty. Patients were divided into two groups according to low and high CHA2DS2-VASc score. Angiographic results of reperfusion were inspected to evaluate the association of high CHA2DS2-VASc score and the likelihood of suboptimal TIMI flow. The secondary endpoint of the study was short-term in-hospital mortality of all cause. Results: The present study confirmed that CHA2DS2-VASc model enables us to determine the risk of no-reflow and all-cause in-hospital mortality independently. Odds ratios were 1.59 (1.30–2.25) and 1.60 (1.17–2.19), respectively. Moreover, BMI, high thrombus grade, and cardiogenic shock were predictors of failed reperfusion (odds were 1.07 (1.01–1.35), 1.59 (1.28–1.76), and 8.65 (3.76–24.46), respectively). We showed that using a cut off value of ≥ two in CHA2DS2-VASc model provides a sensitivity of 69.7% and specificity of 64.4% for discrimination of increased mortality hazards. Area under the curve: 0.72 with 95% CI (0.62–0.81). Conclusions: Calculation of CHA2DS2-VASc score applied as a simple risk stratification tool before primary PCI affords great predictive power. Furthermore, incremental values are obtained by using both CHA2DS2-VASc and no-reflow regarding mortality risk assessment.

Abstract
BACKGROUND Several studies have shown that patients with type 2 diabetes mellitus (T2DM) have worse clinical outcomes in comparison to patients without diabetes mellitus (DM) following Percutaneous Coronary Intervention (PCI). However, the adverse clinical outcomes were not similarly reported in all the studies. Therefore, in order to standardize this issue, a meta-analysis including 139,774 patients was carried out to compare the in-hospital, short-term (<1 year) and long-term (≥1 year) adverse clinical outcomes in patients with and without T2DM following PCI. METHODS Electronic databases including MEDLINE, EMBASE, and the Cochrane Library were searched for Randomized Controlled Trials (RCTs) and observational studies. The adverse clinical outcomes which were analyzed included mortality, myocardial infarction (MI), major adverse cardiac events (MACEs), stroke, bleeding, target vessel revascularization (TVR), target lesion revascularization (TLR), and stent thrombosis. Risk Ratios (RR) with 95% confidence intervals (CI) were used to express the pooled effect on discontinuous variables and the analysis was carried out by RevMan 5.3 software. RESULTS A total number of 139,774 participants were assessed. Results of this analysis showed that in-hospital mortality and MACEs were significantly higher in patients with T2DM (RR 2.57; 95% CI: 1.95-3.38; P = .00001) and (RR: 1.38; 95% CI: 1.10-1.73; P = .005) respectively. In addition, majority of the short and long-term adverse clinical outcomes were also significantly higher in the DM group as compared to the non-DM group. Stent thrombosis was significantly higher in the DM compared to the non-DM group during the short term follow-up period (RR 1.59; 95% CI: 1.16-2.18;P = .004). However, long-term stent thrombosis was similarly manifested. CONCLUSION According to this meta-analysis including a total number of 139,774 patients, following PCI, those patients with T2DM suffered more in-hospital, short as well as long-term adverse outcomes as reported by most of the Randomized Controlled Trials and Observational studies, compared to those patients without diabetes mellitus.

Abstract
A 69-year-old man who had been hospitalized with acute coronary syndrome (ACS), underwent urgent percutaneous coronary intervention. In the subacute phase, he developed sudden chest pain and hemodynamic deterioration, and urgent coronary angiogram showed multiple coronary artery spasms. The discontinuation of beta-blocker treatment and the administration of a calcium antagonist helped prevent angina attacks. In Japanese patients who tend to have coronary artery spasm, the routine administration of beta-blockers for post-ACS patients with a preserved left ventricular systolic function should be considered carefully.

Abstract
Background Patient with acute coronary syndrome benefits from early revascularization. However, methods for the selection of patients who require urgent revascularization from a variety of patients visiting the emergency room with chest symptoms is not fully established. Electrocardiogram is an easy and rapid procedure, but may contain crucial information not recognized even by well-trained physicians. Objective To make a prediction model for the needs for urgent revascularization from 12-lead electrocardiogram recorded in the emergency room. Method We developed an artificial intelligence model enabling the detection of hidden information from a 12-lead electrocardiogram recorded in the emergency room. Electrocardiograms obtained from consecutive patients visiting the emergency room at Keio University Hospital from January 2012 to April 2018 with chest discomfort was collected. These data were splitted into validation and derivation dataset with no duplication in each dataset. The artificial intelligence model was constructed to select patients who require urgent revascularization within 48 hours. The model was trained with the derivation dataset and tested using the validation dataset. Results Of the consecutive 39,619 patients visiting the emergency room with chest discomfort, 362 underwent urgent revascularization. Of them, 249 were included in the derivation dataset and the remaining 113 were included in validation dataset. For the control, 300 were randomly selected as derivation dataset and another 130 patients were randomly selected for validation dataset from the 39,317 who did not undergo urgent revascularization. On validation, our artificial intelligence model had predictive value of the c-statistics 0.88 (95% CI 0.84–0.93) for detecting patients who required urgent revascularization. Conclusions Our artificial intelligence model provides information to select patients who need urgent revascularization from only 12-leads electrocardiogram in those visiting the emergency room with chest discomfort.

Abstract
AIM We investigated the predictive value of the blood urea nitrogen-to-left ventricular ejection fraction ratio (BUNEFr) to evaluate the risk of contrast-induced nephropathy (CIN) in acute coronary syndrome (ACS) patients who were treated with percutaneous coronary intervention (PCI). METHODS A total of 1010 ACS patients undergoing PCI were included in this study. The serum creatinine level was measured before and within 48-72 h of contrast medium administration. Contrast-induced nephropathy was defined as an absolute increase of 0.3 mg/dL or a relative increase of 25% from baseline serum creatinine within 48-72 h of contrast medium exposure. To evaluate the relation between BUNEFr and CIN, the patients were divided into a CIN group and a no-CIN group. RESULTS A total of 74 patients developed CIN (7.3%). Patients with CIN were older and had a higher BUNEFr than those without. Multivariate analysis showed that age, hypotension or positive inotrope support, history of stroke, contrast volume, and BUNEFr (OR 10.59, 95% CI 2.803-40.070, p = 0.001) were independent predictors of CIN. For the development of CIN, the AUC of a multivariable model that included hypotension or positive inotrope support, history of stroke, and contrast volume was 0.813 (95% CI 0.758-0.857, p < 0.001). When BUNEFr was added to a multivariable model, the AUC was 0.859 (95% CI 0.814-0.894, z = 3.204, difference p = 0.0014). Moreover, the addition of BUNEFr to a multivariable model was associated with a significant net reclassification improvement estimated at 49.4% (p < 0.001) and an integrated discrimination improvement of 0.044 (p = 0.0138). CONCLUSION The BUNEFr may be a useful new predictor of CIN in ACS patients treated with PCI. The inclusion of BUNEFr in a multivariable model could allow improved risk classification in these patients regarding the development of CIN.

Abstract
OBJECTIVES Early endothelialization of drug-eluting stent (DES) is a major challenge to reduce the risk of stent thrombosis and the duration of dual-antiplatelet therapy (DAPT) in high bleeding-risk patients. The aim of the present study is to evaluate very early strut coverage with optical coherence tomography (OCT) of the Synergy stent (Boston Scientific) at 1 month in non-ST segment elevation acute coronary syndrome (NSTE-ACS) patients. METHODS This substudy of the EARLY trial prospectively included NSTE-ACS patients treated with the Synergy DES. OCT analysis of the Synergy stent was performed during a staged PCI of additional lesions at 1 month. The primary endpoint was the percentage of covered struts assessed with OCT at 1 month. RESULTS Twenty-four patients were included, with a mean stent length of 35.9 ± 10.1 mm per patient. The rate of covered struts was 78.5% out of 3839 struts analyzed. Nineteen patients (79.2%) had at least 70% of their struts covered. The average neointimal thickness was 0.0508 ± 0.016 mm. CONCLUSIONS In NSTE-ACS patients undergoing culprit percutaneous coronary intervention with the Synergy stent, the rate of covered struts at 1 month was 78.5%. This rapid coverage is in line with the results of clinical trials demonstrating the safety of short-duration DAPT in selected patients who are at high bleeding risk and treated with new-generation DES options.

Abstract
OBJECTIVE Patients with non ST-segment elevation acute coronary syndromes (NSTE-ACS) and peripheral arterial disease (PAD) present a worse prognosis compared to those without PAD. We sought to describe contemporary trends of in-hospital management and outcome of patients admitted for NSTE-ACS with associated PAD. METHODS We analyzed data from 6 Italian nationwide registries, conducted between 2001 and 2014, including consecutive NSTE-ACS patients. RESULTS Out of 15,867 patients with NSTE-ACS enrolled in the 6 registries, 2226 (14.0%) had a history of PAD. As compared to non-PAD patients, those with PAD had significantly more risk factors and comorbidities (all p < 0.0001) that increased over time. Patients with PAD underwent less frequently coronary angiography (72.0% vs 79.2%, p < 0.0001) and percutaneous coronary intervention (PCI, 42.9% vs 51.8%, p < 0.0001), compared to patients without PAD. Over the years, a progressive and similar increase occurred in the rates of invasive procedures both in patients with and without PAD (both p for trend <0.0001). The crude in-hospital mortality rate did not significantly change over time (p for trend = 0.83). However, as compared to 2001, the risk of death was significantly lower in all other studies performed at different times, after adjustment for multiple comorbidities.. At multivariable analysis, PAD on admission was an independent predictor of in-hospital mortality [odds ratio (OR): 1.75; 95% confidence intervals (CI): 1.35-2.27; p < 0.0001]. CONCLUSIONS Over the 14 years of observation, patients with PAD and NSTE-ACS exhibited worsening baseline characteristics and a progressive increase in invasive procedures. Whereas crude in-hospital mortality did not change over time, we observed a significant reduction in comorbidity-adjusted mortality, as compared to 2001.

Abstract
RATIONALE Antiphospholipid syndrome (APS) combined with acute coronary syndrome (ACS) is rarely reported. PATIENT CONCERNS One male patient with APS was admitted to our hospital, who had recent unstable angina (UA). DIAGNOSIS The preliminary diagnosis of ACS and UA (BraunwaldiB) was then made. INTERVENTIONS This patient received secondary preventative therapy for coronary heart disease (CHD) in combination with percutaneous transluminal coronary angioplasty (PTCA) and implantation of NeoVas Bioresorbable Coronary Scaffold. OUTCOMES The patient was followed up, without new UA episodes were observed at 6 months, 1 year, and 2 year after surgery, respectively. LESSONS It was thus concluded that percutaneous coronary intervention (PCI) is effective for APS patients and NeoVas scaffold implantation is presumed safe.

Abstract
BACKGROUND We evaluated optimal duration of dual antiplatelet therapy (DAPT) after second-generation drug-eluting stent (DES) implantation in acute coronary syndrome (ACS). MATERIAL AND METHODS From pooled analysis of three randomized clinical trials (EXCELLENT, IVUS-XPL, RESET), a total of 2,216 patient with ACS undergoing second-generation DES implantation were selected. Each study randomized patients to a short-duration DAPT arm (n = 1119; ≤6 months) or a standard-duration DAPT arm (n = 1097; ≥12 months). Two-thirds of patients were male, and their mean age was 63 years. Mean DAPT durations were 164 ±76 and 359 ±68 days, respectively. The primary endpoint was composite of cardiac death, myocardial infarction, stent thrombosis, stroke or major bleeding during the first 12 months after implantation, analyzed according to the intention-to-treat population. RESULTS Demographic characteristics were balanced between groups. Mean DAPT duration was 164 and 359 days, respectively. Primary endpoint occurred in 22 patients with short-DAPT and 21 patients with standard-DAPT (2.0% versus 1.9%; hazard ratio [HR] 1.03; 95% confidence interval [CI] 0.56-1.86; p = 0.94). Landmark analysis after six-months, no significant difference in primary endpoint between short and standard duration DAPT (1.0% versus 0.8%; HR 1.22; 95% CI 0.51-2.95; p = 0.66). CONCLUSIONS Short-duration DAPT (≤6 months) demonstrated a similar incidence of net adverse cardiovascular and clinical events at 12 months after second-generation DES in ACS compared with standard duration DAPT (≥12 months). CLINICAL TRIAL REGISTRATION EXCELLENT (ClinicalTrials.gov, NCT00698607), RESET (ClinicalTrials.gov, NCT01145079), IVUS-XPL (ClinicalTrials.gov, NCT01308281).
