Abstract
Acute coronary syndrome is one of the most important differential diagnostic considerations in emergency medicine. It describes the constellation of newly occurring clinical symptoms, often accompanied by typical 12-lead ECG changes and the release of cardiac troponins. The spectrum includes unstable angina pectoris, non-ST-segment elevation myocardial infarction (NSTEMI), and ST-segment elevation myocardial infarction (STEMI). It is important to consistently carry out the diagnostic steps that are crucial for further therapeutic procedures to avoid delaying life-saving invasive coronary diagnostics, without losing sight of the diverse, sometimes time-critical differential diagnoses. Anamnesis and clinical examination form the basis of the further procedure. Further developments of biomarker assays with personalized limit values, new imaging modalities with ever higher resolution and faster imaging methods as well as advances in automated ECG analysis with integration of all findings through artificial intelligence will continue to offer many optimization options in the future diagnosis of acute coronary syndrome.

Meter M, Borovac JA. A Refractory Electrical Storm after Acute Myocardial Infarction: The Role of Temporary Ventricular Overdrive Pacing as a Bridge to ICD Implantation. PATHOPHYSIOLOGY 2024; 31:44-51. [PMID: 38251048 PMCID: PMC10801483 DOI: 10.3390/pathophysiology31010004] [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: 12/17/2023] [Revised: 01/10/2024] [Accepted: 01/11/2024] [Indexed: 01/23/2024] Open
Abstract
An electrical storm (ES) is defined as the presence of at least three episodes of sustained ventricular tachycardia or ventricular fibrillation within 24 h. This patient had a previously known arterial hypertension, type II diabetes mellitus, and chronic kidney disease and has presented to the Emergency Department (ED) with symptoms of retrosternal chest pain lasting for several hours prior. The initial 12-lead electrocardiogram revealed ST segment elevation in the anterior leads (V1-V6). Emergent coronary angiography revealed an acute occlusion of the proximal left anterior descending artery (pLAD) and percutaneous coronary intervention was performed with successful implantation of one drug-eluting stent in the pLAD. On day 8 of hospitalization, the patient developed a refractory ES for which he received 50 DC shocks and did not respond to multiple lines of antiarrhythmic medications. Due to a failure of medical therapy, we decided to implant a temporary pacemaker and initiate ventricular overdrive pacing (VOP) that was successful in terminating ES. Following electrical stabilization, the patient underwent a successful ICD implantation. This case demonstrates that VOP can contribute to hemodynamic and electrical stabilization of a patient that suffers from refractory ES and this treatment modality might serve as a temporary bridge to ICD implantation.

Abstract
Tissue engineered cardiac patches have great potential as a regenerative therapy for myocardial infarction. Yet, the mutual interaction of cardiac patches with healthy tissue has not been completely understood. Here, we investigated the impact of acellular and cellular patches on a beating two-dimensional (2D) cardiac cell layer, and the effect of the beating of this layer on the cells encapsulated in the patch. We cultured human-induced pluripotent stem cell-derived cardiomyocytes (iCMs) on a coverslip and placed gelatin methacryloyl hydrogel alone or with encapsulated iCMs to create acellular and cellular patches, respectively. When the acellular patch was placed on the cardiac cell layer, the beating characteristics and Ca+2 handling properties reduced, whereas placing the cellular patch restored these characteristics. To better understand the effects of the cyclic contraction and relaxation induced by the beating cardiac cell layer on the patch placed on top of it, a simulation model was developed, and the calculated strain values were in agreement with the values measured experimentally. Moreover, this dynamic culture induced by the beating 2D iCM layer on the iCMs encapsulated in the cellular patch improved their beating velocity and frequency. Additionally, the encapsulated iCMs were observed to be coupled with the underlying beating 2D iCM layer. Overall, this study provides a detailed investigation on the mutual relationship of acellular/cellular patches with the beating 2D iCM layer, understanding of which would be valuable for developing more advanced cardiac patches.

Prior statin use and the incidence of in-hospital arrhythmia in acute coronary syndrome: A systematic review and meta-analysis. Indian Heart J 2023; 75:9-16. [PMID: 36642406 PMCID: PMC9986741 DOI: 10.1016/j.ihj.2023.01.004] [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: 10/01/2022] [Revised: 12/07/2022] [Accepted: 01/08/2023] [Indexed: 01/15/2023] Open
Abstract
BACKGROUND The benefit of prior statin use to reduce the incidence of arrhythmia in acute coronary syndrome (ACS) is still a matter of debate. Statins have multiple pleiotropic effects, which may reduce the incidence of in-hospital arrhythmia. A systematic review and meta-analysis were performed to evaluate prior statin use and the incidence of in-hospital arrhythmia in ACS. METHODS This systematic review was conducted as per the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA). We performed a literature search through Pubmed, Proquest, EBSCOhost, and Clinicaltrial.gov. A random-effect model was used due to moderate heterogeneity. Quality assessment was performed using Newcastle Ottawa Scale. Sensitivity analysis was performed by using leave one or two out method. PROSPERO registration number: CRD42022336402. RESULTS Nine eligible studies consisting of 86,795 patients were included. A total of 22,130 (25.5%) patients were in statin use before the index ACS event. The prevalence of old myocardial infarction, heart failure, hypertension, diabetes mellitus, and chronic renal failure and concomitant treatment with aspirin, clopidogrel, and beta blocker was higher in the prior statin group compared to no previous statin. Overall, prior statin use was associated with a significantly lower incidence of in-hospital arrhythmia during ACS compared to no previous statin (OR 0.60; 95% CI 0.49-0.72; P < 0.00001; I2 = 54%, P-heterogeneity = 0.03). In subgroup analysis, previous statin use reduced the incidence of atrial fibrillation or atrial flutter (OR 0.64; 95% CI 0.43-0.95; P = 0.03; I2 = 73%, P-heterogeneity = 0.01) and ventricular tachycardia or ventricular fibrillation (OR 0.57; 95% CI 0.49-0.65; P < 0.00001; I2 = 8%, P-heterogeneity = 0.35). CONCLUSIONS Based on aggregate patient data, prior statin use may reduce the incidence of in-hospital arrhythmia during ACS, particularly atrial fibrillation or atrial flutter and ventricular tachycardia or ventricular fibrillation.

Abstract
Cardiac electrophysiology is a complex system established by a plethora of inward and outward ion currents in cardiomyocytes generating and conducting electrical signals in the heart. However, not only cardiomyocytes but also other cell types can modulate the heart rhythm. Recently, cardiac macrophages were demonstrated as important players in both electrophysiology and arrhythmogenesis. Cardiac macrophages are a heterogeneous group of immune cells including resident macrophages derived from embryonic and fetal precursors and recruited macrophages derived from circulating monocytes from the bone marrow. Recent studies suggest antiarrhythmic as well as proarrhythmic effects of cardiac macrophages. The proposed mechanisms of how cardiac macrophages affect electrophysiology vary and include both direct and indirect interactions with other cardiac cells. In this review, we provide an overview of the different subsets of macrophages in the heart and their possible interactions with cardiomyocytes under both physiologic conditions and heart disease. Furthermore, we elucidate similarities and differences between human, murine and porcine cardiac macrophages, thus providing detailed information for researchers investigating cardiac macrophages in important animal species for electrophysiologic research. Finally, we discuss the pros and cons of mice and pigs to investigate the role of cardiac macrophages in arrhythmogenesis from a translational perspective.

Abstract
BACKGROUND The distribution and prognostic impact of coronary artery disease (CAD) in ES are still under debate. METHODS Consecutive ES patients with implantable cardioverter-defibrillator (ICD) were included retrospectively from 2002 to 2016. Three analyses were applied to characterize ES patients: (a) ES patients without CAD (non-CAD), (b) ES patients with CAD (CAD), and (c) diagnostic findings assessed by coronary angiography (CA) at the time of ES (immediate CA). CAD was compared with non-CAD ES patients, and progressive CAD was compared with stable CAD ES patients. The primary endpoint was all-cause mortality at 2.5 years. Secondary endpoints were the composite endpoint of first recurrent ventricular tachyarrhythmias and appropriate ICD therapies, and recurrence of ES (ES-R) at 2.5 years. RESULTS Within a total of 87 consecutive ES patients. CAD was present in more than two-thirds (67%). However, only 52% patients underwent immediate CA at the time of ES. Here, 84% had CAD, of which 39% revealed progressive CAD with the need of target vessel revascularization (TVR) or cardiac transplantation (n = 1). At long-term follow-up, neither the presence (or absence) of CAD (41% vs. 34%; log rank P = 0.708) nor of progressive CAD (33% vs. 26%; log rank P = 0.372) was associated with all-cause mortality at 2.5 years, and further secondary endpoints including the composite of recurrent ventricular tachyarrhythmias plus appropriate ICD therapies, or ES-R. CONCLUSION In ES patients, CAD was more common than non-CAD-related cardiac diseases, accompanied by an underinvestigated rate of CA despite increasing rates of progressive CAD. CAD had no prognostic impact in ES.

Abstract
Tissue engineered cardiac patches have great potential as a therapeutic treatment for myocardial infarction (MI). However, for successful integration with the native tissue and proper function of the cells comprising the patch, it is crucial for these patches to mimic the ordered structure of the native extracellular matrix and the electroconductivity of the human heart. In this study, a new composite construct that can provide both conductive and topographical cues for human induced pluripotent stem cell derived cardiomyocytes (iCMs) is developed for cardiac tissue engineering applications. The constructs are fabricated by 3D printing conductive titanium carbide (Ti3C2Tx) MXene in pre-designed patterns on polyethylene glycol (PEG) hydrogels, using aerosol jet printing, at a cell-level resolution and then seeded with iCMs and cultured for one week with no signs of cytotoxicity. The results presented in this work illustrate the vital role of 3D-printed Ti3C2Tx MXene on aligning iCMs with a significant increase in MYH7, SERCA2, and TNNT2 expressions, and with an improved synchronous beating as well as conduction velocity. This study demonstrates that 3D printed Ti3C2Tx MXene can potentially be used to create physiologically relevant cardiac patches for the treatment of MI. STATEMENT OF SIGNIFICANCE: As cardiovascular diseases and specifically myocardial infarction (MI) continue to be the leading cause of death worldwide, it is critical that new clinical interventions be developed. Tissue engineered cardiac patches have shown significant potential as clinical therapeutics to promote recovery following MI. Unfortunately, current constructs lack the ordered structure and electroconductivity of native human heart. In this study, we engineered a composite construct that can provide both conductive and topographical cues for human induced pluripotent stem cell derived cardiomyocytes. By 3D printing conductive Ti3C2Tx MXene in pre-designed patterns on polyethylene glycol hydrogels, using aerosol jet printing, at a cell-level resolution, we developed tissue engineered patches that have the potential for providing a new clinical therapeutic to combat cardiovascular disease.

Abstract
The prognostic role of early (less than 48 h) resuscitated cardiac arrest (ErCA) complicating acute myocardial infarction (AMI) is still controversial. The present study aimed to analyse the short-term and one-year outcomes of patients after ErCA and late resuscitated cardiac arrest (LrCA) compared to patients without cardiac arrest (CA) complicating AMI. Data from the prospective nationwide Polish Registry of Acute Coronary Syndromes (PL-ACS) were used to assess patients with resuscitated cardiac arrest (rCA) after AMI. Baseline clinical characteristics and the predictors of all-cause death were assessed. The all-cause mortality rate, complications, performed procedures, and re-hospitalisations were assessed for the in-hospital period, 30 days after discharge, and 6- and 12-month follow-ups. Among 167,621 cases of AMI, CA occurred in 3564 (2.1%) patients, that is, 3100 (87%) and 464 (13%) patients with ErCA and LrCA, respectively. The mortality rates in the ErCA vs. LrCA and CA vs. non-CA groups were as follows: in-hospital: 32.1% vs. 59.1% (p < 0.0001) and 35.6% vs. 6.0% (p < 0.0001); 30-day: 2.2% vs. 3.2% (p = 0.42) and 9.9% vs. 5.2% (p < 0.0001); 6-month: 9.2% vs. 17.9% (p = 0.0001) and 12.3% vs. 21.1% (p < 0.0001); and 12-month: 12.3% vs. 21.1% (p = 0.001) and 13% vs. 7.7% (p < 0.0001), respectively. ErCA (hazard ratio (HR): 1.54, confidence interval (CI):1.28–1.89; p < 0.0001) and LrCA (HR: 2.34, CI: 1.39–3.93; p = 0.001) increased the risk of 12-month mortality. During the 12-month follow-up, patients after LrCA more frequently required hospitalisation due to heart failure compared to patients after ErCA. ErCA was related to a higher hospitalisation rate due to coronary-related causes and a higher rate of percutaneous coronary intervention. An episode of LrCA was associated with higher in-hospital and long-term mortality compared to ErCA. ErCA and LrCA were independent risk factors for one-year mortality.

Abstract
Tachyarrhythmias are common complications of critically ill patients treated on intensive care units. Landiolol is an ultra-short acting beta-blocker with a very high beta1-selectivity. Therefore, landiolol effectively reduces heart rate with only minimal negative effects on blood pressure and inotropy. This article describes two cases of successful treatment of supraventricular and ventricular tachycardias with landiolol in critically ill patients.

De novo and pre-existing atrial fibrillation in acute coronary syndromes: impact on prognosis and cardiovascular events in long-term follow-up. EUROPEAN HEART JOURNAL. ACUTE CARDIOVASCULAR CARE 2021; 10:1129-1139. [PMID: 34718473 DOI: 10.1093/ehjacc/zuab091] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/05/2021] [Revised: 09/21/2021] [Accepted: 09/28/2021] [Indexed: 06/13/2023]
Abstract
AIMS The aim of the study was to compare in-hospital and long-term prognosis in patients with acute coronary syndromes (ACS) and de novo vs. pre-existing atrial fibrillation (AF). Atrial fibrillation increases the risk of serious adverse events including death in patients with ACS. However, it is unclear whether de novo and pre-existing AF portend a different risk. METHODS AND RESULTS We analysed the incidence, clinical characteristics, and in-hospital and long-term outcomes in patients with AF and ACS based on combined data from Polish Registry of Acute Coronary Syndrome (PL-ACS) (n = 581 843) and SILICARD (n = 852 063) databases. Atrial fibrillation at admission was diagnosed in of 6.16% patients [de novo: 1129 (2.46%); pre-existing: 1691 (3.7%)]. Groups were compared (N = 1023 vs. 1023) after matching for relevant clinical factors. De novo and pre-existing AF differed in in-hospital diuretic (52% vs. 58%; P = 0.008) and aldosterone inhibitor (27.5% vs. 32.5%; P = 0.02) use, Thrombolysis In Myocardial Infarction (TIMI) flow before percutaneous coronary intervention (P = 0.016), and diuretic (52.1% vs. 58%; P = 0.008) and oral anticoagulant (27.5% vs. 32.5%; P = 0.018) use at discharge. In-hospital mortality in the de novo AF group was significantly higher (13.1% vs. 8.31%; P = 0.0005). Post-discharge 12-month survival was similar between groups (14.5% vs. 15.3%, P = 0.63). Long-term re-hospitalization due to heart failure (22.7% vs. 17.2%; P < 0.005) and medical contact due to AF (48.4% vs. 26.1%, P < 0.0001) rates were higher in the group with pre-existing AF, without the difference of stroke or myocardial infarction occurrence. CONCLUSION De novo AF accounts for 40% of all AF cases in ACS patients and is an unfavourable in-hospital prognostic factor. The occurrence of de novo AF during ACS should require special attention and caution in the treatment of these patients.

Abstract
Both acute myocardial infarction complicated by ventricular tachyarrhythmias (AMI-VTA) and electrical storm (ES) represent life-threatening clinical conditions. However, a direct comparison of both sub-groups regarding prognostic endpoints has never been investigated. All consecutive implantable cardioverter-defibrillator (ICD) recipients were included retrospectively from 2002 to 2016. Patients with ES apart from AMI (ES) were compared to patients with AMI accompanied by ventricular tachyarrhythmias (AMI-VTA). The primary endpoint was all-cause mortality at 3 years, secondary endpoints were in-hospital mortality, rehospitalization rates and major adverse cardiac event (MACE) at 3 years. A total of 198 consecutive ICD recipients were included (AMI-VTA: 56%; ST-segment elevation myocardial infarction (STEMI): 22%; non-ST-segment myocardial infarction (NSTEMI) 78%; ES: 44%). ES patients were older and had higher rates of severely reduced left ventricular ejection fraction (LVEF) < 35%. ES was associated with increased all-cause mortality at 3 years (37% vs. 19%; p = 0.001; hazard ratio [HR] = 2.242; 95% CI 2.291-3.894; p = 0.004) and with increased risk of first cardiac rehospitalization (44% vs. 12%; p = 0.001; HR = 4.694; 95% CI 2.498-8.823; p = 0.001). This worse prognosis of ES compared to AMI-VTA was still evident after multivariable adjustment (long-term all-cause mortality: HR = 2.504; 95% CI 1.093-5.739; p = 0.030; first cardiac rehospitalization: HR = 2.887; 95% CI 1.240-6.720; p = 0.014). In contrast, the rates of MACE (40% vs. 32%; p = 0.326) were comparable in both groups. At long-term follow-up of 3 years, ES was associated with higher rates of all-cause mortality and rehospitalization compared to patients with AMI-VTA.

Abstract
OBJECTIVES To evaluate clinical characteristics and prognosis of patients presented with acute coronary syndrome (ACS) that developed ventricular tachyarrhythmia VTA and to analyse it according to the period of presentation. BACKGROUND VTA is an infrequent yet serious complication of ACS. There is limited data regarding the incidence and prognostic implications of VTA in the last decade as compared with the previous decade. METHODS We evaluated clinical characteristics, major adverse cardiovascular events, short and long- term mortality of patients hospitalised with ACS who were enrolled in the Acute Coronary Syndrome Israeli Survey (ACSIS) during the years 2000-2016. Patients were classified into three groups: no VTA, early VTA (≤48 hours of onset) and late VTA (>48 hours of onset). Data were analysed according to the period of presentation: early vs late period (years 2000-2006 and 2008-2016 accordingly). RESULTS The study population comprised 15,200 patients. VTA occurred in 487 (3.2%) patients. Early VTA presented in 373/487 (77%) patients and late VTA in 114/487 (23%) patients. VTA's, occurring in ACS patients were associated with increased risk of in-hospital, 30-days, 1-year and 5-year mortality rates during both early and late periods compared with no VTA. Moreover, late VTA was associated with the highest mortality rate with up to 65% in 5-year follow up (P < .001). Nevertheless, late VTA was associated with a lower mortality rate in the late period compared with the early period. CONCLUSIONS Any VTA following ACS was associated with high short- and long-term mortality rate. However, over the late period, there has been a significant improvement in survival rates, especially in patients with late VTA. This may be attributed to early and invasive reperfusion therapy, implantable cardioverter-defibrillator implantation and better medical treatment.

Abstract
BACKGROUND AND AIMS Low serum albumin (SA) is associated with an increased risk of long-term adverse events (AEs) among patients with chronic coronary syndromes. Its prognostic role in patients with ST-elevation myocardial infarction (STEMI) is less clear. To investigate the association between low SA and in-hospital AEs in STEMI patients. METHODS AND RESULTS Multicenter retrospective cohort study of 220 STEMI patients undergoing primary percutaneous coronary intervention within 12 h from the onset of symptoms. Hypoalbuminemia was defined by serum SA <35 g/L. SA. In-hospital AEs were defined as cardiogenic shock, resuscitated cardiac arrest and death. Median SA was 38 (IQR 35.4-41.0) g/L and 37 (16.8%) patients showed hypoalbuminemia (<35 g/L) on admission. Patients with hypoalbuminemia were older, more frequently women and diabetics, prior CAD and HF. Furthermore, they showed lower hemoglobin levels and impaired renal function. At multivariable logistic regression analysis, diabetes (odds ratio [OR]:4.59, 95% confidence interval [CI] 1.71-12.28, p = 0.002) and haemoglobin (OR:0.52, 95%CI 0.37-0.72, p < 0.001) were associated with low SA. In a subgroup of 132 patients, SA inversely correlated with D-Dimer (rS -0.308, p < 0.001). Globally, twenty-eight (14.6%) AEs were recorded. Hypoalbuminemia (OR:3.43, 95%CI 1.30-9.07, p = 0.013), high-sensitive (HS)-Troponin peak above median (OR:5.41, 95%CI 1.99-14.7, p = 0.001), C-reactive protein (CRP) peak above median (OR:6.03, 95%CI 2.02-18.00, p = 0.001), and in-hospital infection (OR:3.61, 95%CI 1.21-10.80, p = 0.022) were associated with AEs. CONCLUSION Low SA levels are associated with worse in-hospital AEs in STEMI patients, irrespective of HS-troponin and CRP plasma levels. Our findings suggest that low SA may contribute to the pro-thrombotic phenotype of these patients.

Abstract
OBJECTIVE The incidence of atrial fibrillation (AF) in patients with ST segment elevation myocardial infarction (STEMI) varies between 7% and 21%, and most of these studies were in the thrombolytic era. However, the frequency of new-onset AF during the primary percutaneous coronary intervention (PCI) period is still unclear. We aimed to investigate the frequency of new-onset AF and its effects on long-term clinical events in patients undergoing primary PCI. METHODS A total of 1,603 patients who were diagnosed with STEMI and underwent primary PCI were included in the study. All the patients were monitored for at least 48 hours after the procedure. The primary endpoint of the study was defined as new-onset AF during hospitalization. RESULTS The median follow-up period of our study was 44 months. New-onset AF developed in 85 (6.1%) patients. CHADs-VASc > 2, KILLIP > 2, and left atrial diameter were found to be independent predictors for the development of new-onset AF. In the AF (+) group, the all-cause and in-hospital mortality rates were found to be significantly higher. New-onset AF development in patients with STEMI was detected as an independent predictor of in-hospital mortality. CONCLUSION In the era of primary percutaneous transluminal coronary angioplasty, new-onset AF rates were found to be lower than the literature data. In addition, new-onset AF was found to be a predictor of in-hospital mortality, and deaths occurred mostly in the early period. Therefore, close follow-up of these patients in the early period and re-evaluation in terms of AF burden when the patient becomes stable are important.

Abstract
Cardiac arrhythmias are a leading cause of morbidity and mortality in the developed world. A common mechanism underlying many of these arrhythmias is re-entry, which may occur when native conduction pathways are disrupted, often by myocardial infarction. Presently, re-entrant arrhythmias are most commonly treated with antiarrhythmic drugs and myocardial ablation, although both treatment methods are associated with adverse side effects and limited efficacy. In recent years, significant advancements in the field of biomaterials science have spurred increased interest in the development of novel therapies that enable restoration of native conduction in damaged or diseased myocardium. In this review, we assess the current landscape of materials-based approaches to eliminating re-entrant arrhythmias. These approaches potentially pave the way for the eventual replacement of myocardial ablation as a preferred therapy for such pathologies.

Abstract
The increasing complexity of cardiovascular interventions requires advanced peri-procedural imaging and tailored treatment. Three-dimensional printing technology represents one of the most significant advances in the field of cardiac imaging, interventional cardiology or cardiovascular surgery. Patient-specific models may provide substantial information on intervention planning in complex cardiovascular diseases, and volumetric medical imaging from CT or MRI can be translated into patient-specific 3D models using advanced post-processing applications. 3D printing and additive manufacturing have a great variety of clinical applications targeting anatomy, implants and devices, assisting optimal interventional treatment and post-interventional evaluation. Although the 3D printing technology still lacks scientific evidence, its benefits have been shown in structural heart diseases as well as for treatment of complex arrhythmias and corrective surgery interventions. Recent development has enabled transformation of conventional 3D printing into complex 3D functional living tissues contributing to regenerative medicine through engineered bionic materials such hydrogels, cell suspensions or matrix components. This review aims to present the most recent clinical applications of 3D printing in cardiovascular medicine, highlighting also the potential for future development of this revolutionary technology in the medical field.

Abstract
AIMS The Cardiac Arrhythmias and RIsk Stratification after Myocardial infArction (CARISMA) study was an observational trial including 312 patients with acute myocardial infarction (MI) and left ventricular ejection fraction (LVEF) <40%. Primary percutaneous intervention (pPCI) was introduced 2 years after start of the enrolment, dividing the population into two groups: pre- and post-pPCI. This substudy sought to describe the influence of the mode of revascularization on long-term risk of new-onset atrial fibrillation (AF), bradyarrhythmia, and ventricular tachycardia and the subsequent risk of relevant major cardiovascular events (MACE). METHODS AND RESULTS The study included the 268 patients without a history of AF. All patients received an implantable cardiac monitor (ICM) and were followed for 2 years. The choice of revascularization was made by the treating team independently of the trial and retrospectively divided into pPCI, subacute PCI, primary thrombolysis, or no revascularization. Endpoints were new-onset arrhythmia and MACE.A total of 77 patients received no revascularization, whereas 49 received thrombolysis only and 142 received any PCI. The adjusted hazard ratio (HR) for developing any arrhythmia and the subsequently risk of MACE were increased in non-revascularized or thrombolysed patients compared with PCI-patients (any arrhythmia, non-revascularization: HR = 1.7, P = 0.01 and thrombolysis: HR = 1.6, P = 0.05; MACE, non-revascularization: HR = 3.1, P = 0.05 and thrombolysis: HR = 3.1, P = 0.08). All HRs were adjusted for significant baseline and clinically considered covariates and stratified for calendar year. CONCLUSION This study is the first to demonstrate that the long-term risk of arrhythmia documented by an ICM and the subsequent risk of MACE were increased in non-revascularized or thrombolysed patients compared with PCI-patients in a post-MI population with LVEF <40%.

Fundamento As arritmias ventriculares (AVs) são a principal causa de mortalidade e morbidade hospitalar em pacientes com síndrome coronariana aguda (SCA) e sua relação com o tiol é desconhecida. Objetivo Investigar a relação entre os níveis plasmáticos de tióis e os níveis de troponina em pacientes com SCA e estimar o desenvolvimento de AV intra-hospitalar durante a internação. Método O estudo incluiu 231 pacientes consecutivos com SCA com supradesnivelamento do segmento ST (SCA-SDST) e pacientes com SCA sem supradesnivelamento do segmento ST (SCA-SSDST). Após a aplicação dos critérios de exclusão, 191 pacientes foram incluídos na análise estatística. Os pacientes foram classificados em dois grupos: grupo SCA-SDST (n=94) e grupo SCA-SSDST (n=97). Os níveis plasmáticos de tiol, dissulfeto e troponina foram medidos e a razão de troponina para tiol nativo (RTTN) foi calculada. Considerou-se estatisticamente significativo um valor de p bilateral inferior a 0,05. Resultados Tiol nativo plasmático, tiol total, dissulfeto e suas razões foram semelhantes entre os grupos. A RTTN se mostrou significativamente maior no grupo SCA-SDST em comparação com o grupo SCA-SSDST. Houve correlação negativa significativa entre os níveis de troponina e tiol. Verificou-se que o tiol nativo é preditor independente do desenvolvimento de AV em pacientes com SCA-SDST e em todos os pacientes com SCA. Verificou-se que o RTTN é preditor independente do desenvolvimento de AV em pacientes com SCA-SSDST e em todos os pacientes com SCA. Conclusão Os níveis plasmáticos de tiol podem ser usados para identificar pacientes com alto risco de desenvolvimento de AV intra-hospitalar em pacientes com SCA. A correlação entre os níveis de troponina e tiol pode sugerir que os tióis possam ser marcadores importantes para o diagnóstico e prognóstico da SCA com a ajuda de estudos futuros.

Abstract
INTRODUCTION Atrial fibrillation (AF) is a frequent finding in acute coronary syndrome (ACS), but there is conflicting scientific evidence regarding its long-term impact on patient outcome. The aim of this study was to survey and compare the ≥10-year mortality of ACS patients with sinus rhythm (SR) and AF. METHODS Patients were divided into 2 groups based on rhythm in their 12-lead ECGs: (1) SR (n = 788) at hospital admission and discharge (including sinus bradycardia, physiological sinus arrhythmia, and sinus tachycardia) and (2) AF/atrial flutter (n = 245) at both hospital admission and discharge, or SR and AF combination. Patients who failed to match the inclusion criteria were excluded from the final analysis. The main outcome surveyed was long-term all-cause mortality between AF and SR groups during the whole follow-up time. RESULTS Consecutive ACS patients (n = 1,188, median age 73 years, male/female 58/42%) were included and followed up for ≥10 years. AF patients were older (median age 77 vs. 71 years, p < 0.001) and more often female than SR patients. AF patients more often presented with non-ST-elevation myocardial infarction (69.8 vs. 50.4%, p < 0.001), had a higher rate of diabetes (31.0 vs. 22.8%, p = 0.009), and were more often using warfarin (32.2 vs. 5.1%, p < 0.001) or diuretic medication (55.1 vs. 25.8%, p < 0.001) on admission than patients with SR. The use of warfarin at discharge was also more frequent in the AF group (55.5 vs. 14.8%, p < 0.001). The rates of all-cause and cardiovascular mortality were higher in the AF group (80.9 vs. 50.3%, p < 0.001, and 73.8 vs. 69.6%, p = 0.285, respectively). In multivariable analysis, AF was independently associated with higher mortality when compared to SR (adjusted HR 1.662; 95% CI: 1.387-1.992, p < 0.001). CONCLUSION AF/atrial flutter at admission and/or discharge independently predicted poorer long-term outcome in ACS patients, with 66% higher mortality within the ≥10-year follow-up time when compared to patients with SR.

Abstract
BACKGROUND New-onset atrial fibrillation (NOAF), both early (EAF) or late (LAF), may complicate ST-segment elevation myocardial infarction (STEMI). The mechanisms underlying EAF or LAF are poorly described. We investigated atrial branch occlusion and EAF or LAF onset in STEMI patients undergoing primary percutaneous coronary intervention. METHODS This was a retrospective cohort study including 155 STEMI patients. Patients were divided into 3 groups: sinus rhythm (SR), EAF, or LAF. Clinical characteristics, angiographic features including occlusion of atrial branches, namely ramus ostia cavae superioris (ROCS), atrio-ventricular node artery (AVNA), right intermediate atrial artery (RIAA), and left intermediate atrial artery, were assessed. We also investigated in-hospital adverse events (AEs) and death. RESULTS Mean age was 63.8±11.9 years; 78.7% were men. NOAF was detected in 22 (14.2%) patients: 10 (6.4%) EAF and 12 LAF (7.7%). Compared to EAF, LAF patients were older (p=0.013), with higher GRACE risk score (p=0.014) and Killip class (p=0.015), depressed ejection fraction (p=0.007), elevated filling pressures (p=0.029), higher C-reactive protein (p=0.014) and more with thrombolysis in myocardial infarction flow <3 (p=0.015). Compared to SR, EAF was associated with higher prevalence of occluded ROCS (p=0.010), AVNA (p=0.005), and RIAA (p<0.001). Moreover, EAF patients had more frequently ≥2 diseased atrial branches than SR (19.5%, p<0.001) and LAF (25%, p<0.030) patients. LAF patients had a higher in-hospital AEs (p=0.019 vs SR; p=0.029 vs EAF) and death (p=0.004 vs SR). CONCLUSIONS The occlusion of atrial branches is associated with EAF but not LAF following STEMI. LAF patients had worse in-hospital AEs and mortality.

Abstract
Engineered cardiac tissues fabricated from human induced pluripotent stem cells (hiPSCs) show promise for ameliorating damage from myocardial infarction, while also restoring function to the damaged left ventricular (LV) myocardium. For these constructs to reach their clinical potential, they need to be of a clinically relevant volume and thickness, and capable of generating synchronous and forceful contraction to assist the pumping action of the recipient heart. Design prerequisites include a structure thickness sufficient to produce a beneficial contractile force, prevascularization to overcome diffusion limitations and sufficient structural development to allow for maximal cell communication. Previous attempts to meet these prerequisites have been hindered by lack of oxygen and nutrient transport due to diffusion limits (100–200 μm) resulting in necrosis. This study employs a layer-by-layer (LbL) fabrication method to produce cardiac tissue constructs that meet these design prerequisites and mimic normal myocardium in form and function. Thick (>2 mm) cardiac tissues created from hiPSC-derived cardiomyocytes, -endothelial cells (ECs) and -fibroblasts (FBs) were assessed, in vitro, over a 4-week period for viability (<6% necrotic cells), cell morphology and functionality. Functional performance assessment showed enhanced t-tubule network development, gap junction communication as well as previously unseen, physiologically relevant conduction velocities (CVs) (>30 cm/s). These results demonstrate that LbL fabrication can be utilized successfully to create prevascularized, functional cardiac tissue constructs from hiPSCs for potential therapeutic applications.

Abstract
Background Myocardial reperfusion may cause profound electrophysiological alterations and can lead to serious reperfusion arrhythmias (RA). Management of RA and the accompanying electrical storm that may occur remains a problem. To our knowledge, the role of balloon re-inflation of the infarct-related artery (IRA) has never been addressed as a treatment modality for RA presenting as ventricular tachycardia (VT) with pulse or supraventricular tachycardia (SVT). Case presentation Six patients presenting with ST elevation myocardial infarction (STEMI) in the first 12 h, who underwent successful primary percutaneous coronary intervention (PCI), developed RA in the cathlab after restoration of flow in the IRA. The RA was in the form of VT with pulse, except in one patient who had SVT. In four patients, the RA was associated with hemodynamic instability. The mean age of the studied patients was 59.16 ± 7.94 years, and four were males. Coronary artery disease risk factors were prevalent, with four patients being hypertensive, two dyslipidemic, one diabetic, and 2 current smokers. One patient had a history of prior myocardial infarction (MI), and none had a history of congestive heart failure. The coronary angiography showed 100% occlusion of IRA in all patients and 2–3-vessel disease was present in 50%. PCI was successful with restoration of thrombolysis in myocardial infarction (TIMI) 2–3 flow in IRA in all cases. The mean time to revascularization from the onset of chest pain was 4.88 ± 2.68 h. In all cases, balloon re-inflation was successful in terminating the arrhythmias. None of the patients needed direct current cardioversion or anti-arrhythmic drugs for management of the acute arrhythmia. Conclusion Balloon re-inflation of IRA was successful in terminating RA that develop in the form of VT with pulse or SVT.

Abstract
Background Acute myocardial infarction (AMI) is the most life-threatening manifestation of coronary artery diseases. The majority of deaths in AMI are due to arrhythmias. Therefore, the aim of this study was to evaluate the incidence and risk factors and outcomes of cardiac arrhythmias in AMI patients undergoing primary percutaneous coronary intervention (PCI) during the first 24 hours of the index hospitalization. Methodology This prospective observational study was conducted at the adult cardiology department of the National Institute of Cardiovascular Diseases (NICVD), Karachi, Pakistan. Patients undergoing primary PCI were included in this study. All the patients were kept under observation for the first 24 hours of AMI and monitored through telemetry system monitoring and the incidence of cardiac arrhythmias and the outcomes were recorded. Results A total of 110 patients were included; the mean age was 59.6±13.1 years. Most of them were male (70.9%). Arrhythmias were observed in 89.1% of the patients, with 169 episodes. The accelerated idioventricular rhythm was the most common type of arrhythmia (37.3%) followed by sinus tachycardia (36.4%), ventricular tachycardia (22.7%), and complete heart block (20.0%). Lethal arrhythmias were observed in 64.5% (71) of the patients. During the hospital course, 65.5% developed arrhythmias during arrival to balloon time, 30% during the procedure, and 53.6% within 24 hours of the procedure. The in-hospital mortality rate was 15.5% with a significant association with the development of lethal arrhythmias within 24 hours of the procedure (21.1% vs. 5.1%; p=0.026). Conclusions The incidence of arrhythmias within 24 hours of hospitalization is high in patients with ST-elevation myocardial infarction (STEMI) undergoing primary PCI, and it has been observed to be associated with an increased rate of in-hospital mortality.

Abstract
Background The 2017 ESC guideline on patients with ST-segment elevation myocardial infarction (STEMI) provides guidance regarding the optimal management of these patients. Transient atrioventricular (AV) block is a relatively common complication of inferior STEMI and its management is also addressed in the guidelines. Case summary A 64-year-old gentleman with multiple cardiovascular risk factors presented to the emergency department with a history of ischaemic type chest pain and evidence of inferior ST-segment elevation on his electrocardiogram (ECG). First-degree AV block was noted on his initial ECG. He was given thrombolytic therapy as part of a pharmacoinvasive strategy of reperfusion. He, however, failed fibrinolytic therapy, and emergency angiography revealed critical disease of the right coronary artery which was successfully stented. Subsequent to reperfusion, he developed complete AV block without evidence of re-infarction, which was managed conservatively with successful resolution of the block after 7 days of expectant management with temporary transvenous pacing. Discussion We highlight some of the important management principles from the ESC guideline of STEMI including timing and the management of AV block in these patients. In addition, we highlight the role of a pharmacoinvasive strategy for reperfusion where timeous primary percutaneous coronary intervention cannot be performed. The usefulness of such a strategy within the COVID-19 era is also emphasized.

Abstract
Despite major therapeutic advances over the last decades, complex supraventricular and ventricular arrhythmias (VAs), particularly in the emergency setting or during revascularization for acute myocardial infarction (AMI), remain an important clinical problem. Although the incidence of VAs has declined in the hospital phase of acute coronary syndromes (ACS), mainly due to prompt revascularization and optimal medical therapy, still up to 6% patients with ACS develop ventricular tachycardia and/or ventricular fibrillation within the first hours of ACS symptoms. Despite sustained VAs being perceived predictors of worse in-hospital outcomes, specific associations between the type of VAs, arrhythmia timing, applied treatment strategies and long-term prognosis in AMI are vague. Atrial fibrillation (AF) is the most common supraventricular tachyarrhythmia that may be asymptomatic and/or may be associated with rapid haemodynamic deterioration requiring immediate treatment. It is estimated that over 20% AMI patients may have a history of AF, whereas the new-onset arrhythmia may occur in 5% patients with ST elevation myocardial infarction. Importantly, patients who were treated with primary percutaneous coronary intervention for AMI and developed AF have higher rates of adverse events and mortality compared with subjects free of arrhythmia. The scope of this position document is to cover the clinical implications and pharmacological/non-pharmacological management of arrhythmias in emergency presentations and during revascularization. Current evidence for clinical relevance of specific types of VAs complicating AMI in relation to arrhythmia timing has been discussed.

The emergence of coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a major global public health concern. Although SARS-CoV-2 causes primarily respiratory problems, concurrent cardiac injury cannot be ignored since it may be an independent predictor for adverse outcomes. Cardiac arrhythmias are often observed in patients with COVID-19, especially in severe cases, and more likely contribute to the high risk of adverse outcomes. Arrhythmias should be regarded as one of the main complications of COVID-19. Mechanistically, a number of ion channels can be adversely affected in COVID-19, leading to alterations in cardiac conduction and/or repolarization properties, as well as calcium handling, which can predispose to cardiac arrhythmogenesis. In addition, several antimicrobials that are currently used as potential therapeutic agents for COVID-19, such as chloroquine, hydroxychloroquine and azithromycin, have uncertain benefit, and yet may induce electrocardiographic QT prolongation with potential ventricular pro-arrhythmic effects. Continuous electrocardiogram monitoring, accurate and prompt recognition of arrhythmias are important. The present review focuses on cardiac arrhythmias in patients with COVID-19, its underlying mechanisms, and proposed preventive and therapeutic strategies.

Abstract
In the heart, cardiac macrophages have widespread biological functions, including roles in antigen presentation, phagocytosis, and immunoregulation, through the formation of diverse cytokines and growth factors; thus, these cells play an active role in tissue repair after heart injury. Recent clinical studies have indicated that macrophages or elevated inflammatory cytokines secreted by macrophages are closely related to ventricular arrhythmias (VAs). This review describes the role of macrophages and macrophage-secreted inflammatory cytokines in ventricular arrhythmogenesis.

Abstract
Coronavirus disease 19 (COVID-19) and its associated restrictions could affect ischemic times in patients with ST-segment elevation myocardial infarction (STEMI). The objective of this study was to investigate the influence of the COVID-19 outbreak on ischemic times in consecutive all-comer STEMI patients. We included consecutive STEMI patients (n = 163, median age: 61 years, 27% women) who were referred to seven tertiary care hospitals across Austria for primary percutaneous coronary intervention between 24 February 2020 (calendar week 9) and 5 April 2020 (calendar week 14). The number of patients, total ischemic times and door-to-balloon times in temporal relation to COVID-19-related restrictions and infection rates were analyzed. While rates of STEMI admissions decreased (calendar week 9/10 (n = 69, 42%); calendar week 11/12 (n = 51, 31%); calendar week 13/14 (n = 43, 26%)), total ischemic times increased from 164 (interquartile range (IQR): 107-281) min (calendar week 9/10) to 237 (IQR: 141-560) min (calendar week 11/12) and to 275 (IQR: 170-590) min (calendar week 13/14) (p = 0.006). Door-to-balloon times were constant (p = 0.60). There was a significant difference in post-interventional Thrombolysis in myocardial infarction (TIMI) flow grade 3 in patients treated during calendar week 9/10 (97%), 11/12 (84%) and 13/14 (81%; p = 0.02). Rates of in-hospital death and re-infarction were similar between groups (p = 0.48). Results were comparable when dichotomizing data on 10 March and 16 March 2020, when official restrictions were executed. In this cohort of all-comer STEMI patients, we observed a 1.7-fold increase in ischemic time during the outbreak of COVID-19 in Austria. Patient-related factors likely explain most of this increase. Counteractive steps are needed to prevent further cardiac collateral damage during the ongoing COVID-19 pandemic.

Abstract
AIMS ST-elevation myocardial infarction is associated with high levels of cardiac sympathetic drive and release of the co-transmitter neuropeptide Y (NPY). We hypothesized that despite beta-blockade, NPY promotes arrhythmogenesis via ventricular myocyte receptors. METHODS AND RESULTS In 78 patients treated with primary percutaneous coronary intervention, sustained ventricular tachycardia (VT) or fibrillation (VF) occurred in 6 (7.7%) within 48 h. These patients had significantly (P < 0.05) higher venous NPY levels despite the absence of classical risk factors including late presentation, larger infarct size, and beta-blocker usage. Receiver operating curve identified an NPY threshold of 27.3 pg/mL with a sensitivity of 0.83 and a specificity of 0.71. RT-qPCR demonstrated the presence of NPY mRNA in both human and rat stellate ganglia. In the isolated Langendorff perfused rat heart, prolonged (10 Hz, 2 min) stimulation of the stellate ganglia caused significant NPY release. Despite maximal beta-blockade with metoprolol (10 μmol/L), optical mapping of ventricular voltage and calcium (using RH237 and Rhod2) demonstrated an increase in magnitude and shortening in duration of the calcium transient and a significant lowering of ventricular fibrillation threshold. These effects were prevented by the Y1 receptor antagonist BIBO3304 (1 μmol/L). Neuropeptide Y (250 nmol/L) significantly increased the incidence of VT/VF (60% vs. 10%) during experimental ST-elevation ischaemia and reperfusion compared to control, and this could also be prevented by BIBO3304. CONCLUSIONS The co-transmitter NPY is released during sympathetic stimulation and acts as a novel arrhythmic trigger. Drugs inhibiting the Y1 receptor work synergistically with beta-blockade as a new anti-arrhythmic therapy.

Combination of Oral Anticoagulants and Single Antiplatelets versus Triple Therapy in Nonvalvular Atrial Fibrillation and Acute Coronary Syndrome: Stroke Prevention among Asians.

Abstract
Atrial fibrillation (AF), the most prevalent arrhythmic disease, tends to foster thrombus formation due to hemodynamic disturbances, leading to severe disabling and even fatal thromboembolic diseases. Meanwhile, patients with AF may also present with acute coronary syndrome (ACS) and coronary artery disease (CAD) requiring stenting, which creates a clinical dilemma considering that majority of such patients will likely receive oral anticoagulants (OACs) for stroke prevention and require additional double antiplatelet treatment (DAPT) to reduce recurrent cardiac events and in-stent thrombosis. In such cases, the gentle balance between bleeding risk and atherothromboembolic events needs to be carefully considered. Studies have shown that congestive heart failure, hypertension, age ≥ 75 years (doubled), diabetes mellitus, and previous stroke or transient ischemic attack (TIA; doubled)-vascular disease, age 65 to 74 years, sex category (female; CHA 2 DS 2 -VASc) scores outperform other scoring systems in Asian populations and that the hypertension, abnormal renal/liver function (1 point each), stroke, bleeding history or predisposition, labile international normalized ratio (INR), elderly (>65 years), drugs/alcohol concomitantly (1 point each; HAS-BLED) score, a simple clinical score that predicts bleeding risk in patients with AF, particularly among Asians, performs better than other bleeding scores. A high HAS-BLED score should not be used to rule out OAC treatment but should instead prompt clinicians to address correctable risk factors. Therefore, the current review attempted to analyze available data from patients with nonvalvular AF who underwent stenting for ACS or CAD and elaborate on the direct-acting oral anticoagulant (DOAC) and antiplatelet management among such patients. For majority of the patients, "triple therapy" comprising OAC, aspirin, and clopidogrel should be considered for 1 to 6 months following ACS. However, the optimal duration for "triple therapy" would depend on the patient's ischemic and bleeding risks, with DOACs being obviously safer than vitamin-K antagonists.

Abstract
OBJECTIVE Patients with ST-segment elevation myocardial infarction (STEMI) are sometimes boarded in the emergency department (ED) after percutaneous coronary intervention (PCI). We evaluated the effects of direct and indirect admission to the CCU on mortality and the effect on length of stay (LOS) in patients with STEMI. METHOD This was a retrospective observational study of patients with STEMI between Jan 2014 and Nov 2017. The patients were divided into the direct admission (DA) group, who were admitted into the CCU immediately after PCI, and the indirect admission (IA) group, who were admitted after boarding in the ED. The primary endpoint was in-hospital mortality. Secondary endpoints were 3-month mortality, LOS in CCU and hospital, and LOS under intensive care. RESULTS During the study period, 780 patients were enrolled and analyzed. The in-hospital mortality rate and 3-month mortality rate were 5.9% (46 patients) and 8.5% (66 patients). The DA group and IA group had similar in-hospital and 3-month mortality rates (P = .50, P = .28). The median CCU LOS and hospital LOS was similar for both groups (P = .28, P = .46). However, LOS under in intensive care for the IA group was significantly longer than that of the DA group (DA, 31.9 h; IA, 38.7 h; P < .001). CONCLUSION This study suggests that direct admission after PCI and indirect admission was not associated with mortality in patients with STEMI. In addition, the stay in ED also appears to be associated with the duration of stay under critical care.

Abstract
Electrical storm (ES) is a life-threatening condition that is defined by three or more episodes of sustained ventricular tachycardia (VT), ventricular fibrillation (VF), or appropriate shocks from an implantable cardioverter defibrillator (ICD) within 24 hours. The most common form of ES is monomorphic VT. It carries poor outcome despite all available intervention therapies. The therapies include rapid recognition of the condition, treatment of the reversible causes, ICD-reprogramming, antiarrhythmic drugs, sedation, and catheter ablation (CA). The first line antiarrhythmic drugs are amiodarone and β-blockers with superiority of propranolol over the others. The long-term use of the antiarrhythmic drugs is limited due to their adverse effects and drug-related proarrhythmic effect. The basic mechanism of monomorphic VT is re-entry pathway which can be targeted by CA. CA should be considered in drug refractory ES and patients should be referred in early course of disease. There are reported studies which showed the superiority of CA over the medical treatment in reducing the arrythmia burden and ICD appropriate shock. The survival benefit has been reported after successful ablation of ES in case series but to date no randomized control trial shows mortality benefit.

Abstract
New-onset atrial fibrillation (NOAF) has been associated with poor outcome in patients with acute coronary syndromes (ACSs). The objective of this study was to investigate the relationship between the development of NOAF and severity of coronary artery disease using the SYNTAX score (SS) and SYNTAX score II (SSII) in patients with non-ST-segment elevation ACS (NSTE-ACS) who were treated with percutaneous coronary intervention (PCI). A total of 662 patients with NSTE-ACS were consecutively enrolled. The incidence of NOAF was 11.4% among the patients with NSTE-ACS. Mean age was significantly higher in NOAF group ( P = .011). White blood cell count, peak troponin I, high sensitivity C-reactive protein, uric acid, left atrial volume index, and ratio between early mitral inflow velocity and mitral annular early diastolic velocity were significantly higher in NOAF group (respectively, P = .024, P = .017, P = .002, P = .009, P = .025, P < .001, and P < .001). The hemoglobin, ejection fraction, and post PCI thrombolysis in myocardial infarction grade <3 were significantly lower in NOAF group ( P = 001, P = .010, P = .038). The SS and SSII were significantly higher in NOAF group (all P < .001). According to the results of multivariate logistic regression analysis, the SSII was correlated with NOAF ( P < .001) in the study groups. We demonstrated that high SSII is significantly associated with NOAF.

Abstract
INTRODUCTION Contrast-induced nephropathy (CIN) is associated with increased cardiovascular morbidity and mortality in patients with acute coronary syndrome (ACS). Recent studies suggest that CIN is associated with new-onset atrial fibrillation (AF) in patients with acute coronary syndrome (ACS) who underwent catheterization. However, a systematic review and meta-analysis of the literature have not been done. We assessed the association between CIN in patients with ACS and new-onset AF by a systematic review of the literature and a meta-analysis. HYPOTHESIS CIN is associated with new-onset AF in patients with ACS. METHODS We comprehensively searched the databases of MEDLINE and EMBASE from inception to April 2018. Included studies were published cohort studies that compared new-onset AF after cardiac catheterization in ACS patient with CIN versus without CIN. Data from each study were combined using the random effects, generic inverse variance method of DerSimonian and Laird to calculate risk ratios and 95% confidence intervals. RESULTS Five studies from December 2009 to February 2018 were included in this meta-analysis involving 5,640 subjects with ACS (1,102 with CIN and 4,538 without CIN). Contrast-induced nephropathy significantly correlates with new-onset AF after cardiac catheterization (pooled risk ratio = 2.84, 95% confidence interval: 1.66-4.87, p < 0.001, I2 = 58%) CONCLUSIONS: Contrast-induced nephropathy is associated with new-onset AF threefold among patients with ACS after cardiac catheterization. Our study warranted further study to establish the causality between CIN and new-onset AF.

Wang C, Zhao G, Wang X, Nie S. Effect of Potent P2Y 12 Inhibitors on Ventricular Arrhythmias and Cardiac Dysfunction in Coronary Artery Disease: A Systematic Review and Meta-Analysis. BIOMED RESEARCH INTERNATIONAL 2018; 2018:8572740. [PMID: 30648108 PMCID: PMC6311824 DOI: 10.1155/2018/8572740] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/12/2018] [Revised: 11/14/2018] [Accepted: 11/25/2018] [Indexed: 12/12/2022]
Abstract
BACKGROUND Previous studies have shown that P2Y12 receptor inhibitors might prevent ventricular arrhythmias and cardiac dysfunction in patients with coronary artery disease. However, few studies have focused on comparison of the efficacy of novel oral potent P2Y12 receptor inhibitors with clopidogrel on these outcomes. METHODS AND RESULTS We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) that were published in electronic databases of MEDLINE, EMBASE, Cochrane Central Register of Clinical Trials, and ClinicalTrials.gov before June 20, 2018. We compared the effect of prasugrel and ticagrelor with clopidogrel on outcomes of ventricular tachycardia (VT), ventricular fibrillation (VF), heart failure (HF), and cardiogenic shock (CS). Data were combined using both the fixed-effects models and the random-effects models, and the heterogeneity was assessed with the I 2 statistic. Nine RCTs (6 with prasugrel and 3 with ticagrelor) with 45,227 patients were included. Patients receiving prasugrel were associated with a lower risk of combined VT and VF (rate ratio [RR]: 0.72, 95% confidence interval [CI]: 95% CI: 0.52-0.99, p=0.043), as well as combined HF and CS (RR: 0.81, 95% CI: 0.70-0.94, p=0.005), compared with clopidogrel. Patients receiving ticagrelor were also associated with a reduced risk of VT and VF (RR: 0.85, 95% CI: 0.72-1.02, p=0.077), although without statistical significance, but not of HF and CS (RR: 0.96, 95% CI: 0.81-1.13, p=0.620). CONCLUSIONS This meta-analysis of RCTs shows that, compared with clopidogrel, novel oral P2Y12 inhibitors, especially prasugrel, might have better effect on improving ventricular rhythm and cardiac function.

Abstract
OBJECTIVES We aimed to assess the impact of omitting aspirin on clinical outcomes in a real-world collective of patients receiving oral anticoagulation (OAC) therapy who were treated with a current-generation drug-eluting stent (DES) or an everolimus-eluting bioresorbable vascular scaffold (BVS). BACKGROUND Limited data are available regarding the clinical benefit of triple antithrombotic therapy (TAT) with aspirin compared with dual antithrombotic therapy (DAT) without aspirin in patients undergoing percutaneous coronary intervention (PCI) and requiring OAC. METHODS In total, 237 patients were analyzed. The primary outcome was a composite of major adverse cardiac and cerebrovascular events (MACCE) within 1 year after PCI. Secondary outcomes were the individual components of the primary endpoint, cardiovascular death, and any bleeding according to Bleeding Academic Research Consortium (BARC) or Thrombolysis in Myocardial Infarction (TIMI) criteria. RESULTS Eighty-nine patients (37.6%) received DAT, and 148 (62.4%) received TAT. The rate of MACCE was significantly higher in DAT patients than in TAT patients (16 (18%) vs. 11 (7.4%); hazard ratio [HR] 2.73, 95% confidence interval [CI] 1.24-6.03; P = 0.01). The results of the multivariable Cox proportional hazards model including corrections for imbalances in baseline characteristics confirmed a significant independent association between DAT and MACCE (HRadj 3.14, 95% CI 1.31-7.54; P = 0.01). Major bleeding did not differ significantly between treatment groups. CONCLUSION DAT was associated with a significantly higher rate of MACCE than TAT after DES or BVS implantation. Further studies are required to evaluate the safety and efficacy of dual versus TAT after PCI in clinical practice.

Abstract
BACKGROUND The development of atrial fibrillation (AF) during the course of acute coronary syndrome (ACS) is related to poor prognosis. Possible predictors of new-onset AF (NOAF) have not been adequately investigated in elderly patients with ACS undergoing percutaneous coronary intervention (PCI). We aimed to identify the factors associated with NOAF in such patients. METHODS A total of 308 elderly patients with ACS undergoing PCI were enrolled in the study. Patients were divided into two groups: without NOAF [254 patients, 64.6% men, age: 73.5 (69.0-79.0) years] and with NOAF [54 patients, 70.4% men, age: 75.0 (68.7-81.2) years]. Clinical, angiographic, and laboratory features including neutrophil-to-lymphocyte ratio (NLR) and monocyte-to-high-density lipoprotein ratio (MHR) were compared between the groups. RESULTS The percentages of prior myocardial infarction (MI) (20.4 vs. 5.9%) and Killip III/ IV (24.1 vs. 7.1%), NLR [4.5 (2.6-7.2) vs. 3.2 (2.0-6.0)], and MHR [19.4 (15.7-26.5) vs. 12.9 (9.9-18.5)] were higher in patients with NOAF compared to the others (p = 0.020, < 0.001, 0.030, and < 0.001, respectively). In multivariate regression analysis, prior MI (OR 4.509, 95% CI 1.679-12.106, p = 0.003) and MHR (OR 1.102, 95% CI 1.054-1.152, p < 0.001) independently predicted NOAF. In addition, Killip III/IV was found to be an independent predictor of 6-month overall mortality (HR 2.949, 95% CI 1.218-7.136, p = 0.016). CONCLUSIONS Prior MI and MHR are independent predictors of NOAF in elderly patients with ACS undergoing PCI. Killip III/IV predicts 6-month overall mortality in such patients.

Abstract
Atrial fibrillation (AF) is a frequent complication of acute coronary syndromes (ACS) and is associated with an increased risk of in-hospital and long-term mortality. Our objective was to determine whether patients with previous AF and those who presented with or developed AF during their ACS hospitalization (new onset) have an associated increased risk of short- and mid-term cardiovascular events, death, or a composite. We included 7,228 patients from the Global Registry of Acute Coronary Events electrocardiogram core laboratory substudy, who presented with an ACS. Associated multivariable-adjusted risk of death and major adverse cardiovascular events (MACE) of death, re-infarction, or stroke in-hospital and at 6 months were estimated. New-onset AF and previous AF patients had higher rates of in-hospital mortality (14.9% and 10.9%, respectively) compared with patients without AF (3.8%; both p < 0.001). New-onset AF and previous AF patients had higher rates of 6-month mortality (22.3% and 21.3%, respectively) compared with patients without AF (7.0%; both p <0.001). After adjustment for clinical prognosticators, including those in the Global Registry of Acute Coronary Events risk model, new-onset AF was associated with higher mortality in-hospital (ORadj 1.87, 95% CI 1.30 to 2.70) and at 6 months (ORadj 1.75, 95% CI 1.29 to 2.39) as well as MACE at 6 months (ORadj 1.43, 95% CI 1.12 to 1.81) compared with patients without AF, but were at similar risk compared to those with previous AF (all p > 0.40). In conclusion, the risk of death and MACE after ACS in patients with new-onset and previous AF appears similar and significantly increased compared with patients without AF.

Abstract
Atrial fibrillation (AF) is the most common tachyarrhythmia complicating ST segment elevation myocardial infarction (STEMI), while ventricular arrhythmias (VA) can, not only be accompanied by a hemodynamic disorder, but in some cases, worsen its prognosis. The article presents a modern view on risk factors for development of AF (elderly age, left ventricle systolic dysfunction, heart failure, etc.), strategy and tactics of AF treatment in patients with STEMI, the indications for its pharmacological cardioversion and electro-impulse therapy. It is shown that I.V. administration of betablockers and in some cases amiodarone for reducing the frequency of ventricular contractions is advisable. Features and argumentative issues of triple antithrombotic therapy in patients with AF with STEMI, the possibilities and indications for the use of double antithrombotic therapy instead of triple one are described. Clinical significance and peculiarities of treatment of various types of VA have been determined, the role of myocardial revascularization, radiofrequency catheter ablation, normalization of electrolyte imbalance, use of beta-blockers and amiodarone in the prevention and therapy of lifethreatening ventricular arrhythmias has been emphasized. The irrationality, and sometimes the risk of carrying out prophylactic antiarrhythmic therapy for AF and VA in the acute stage of STEMI, as well as the role of the implantable cardioverter-defibrillator in primary prevention of death in certain groups of patients with low left ventricle ejection fraction after myocardial infarction was noted. The value of various antiarrhythmic drugs in their effect on the improvement of prognosis in patients after STEMI is estimated. The material is presented based on modern recommendations for the treatment of patients with STEMI, therapy of AF and VA, prevention of sudden cardiac death, as well as data from several controlled studies and own clinical experience of pharmacotherapy of arrhythmias.
