The aims of the present study were to elucidate features of culprit lesion plaque morphology using optical coherence tomography (OCT) in relation to elevated serum uric acid (sUA) levels and to clarify the impact of sUA levels on adverse clinical outcomes in patients with acute coronary syndrome (ACS). Clinical data and outcomes were compared between ACS patients with sUA ≥6 mg/dl (high-sUA; n = 506) and sUA <6.0 mg/dl (low-sUA; n = 608). Angiography and OCT findings were analyzed in patients with preintervention OCT and compared between groups of high-sUA (n = 206) and low-sUA (n = 273)...

OBJECTIVES: The authors sought to evaluate the influence of coronary microcirculatory dysfunction (CMD) on the diagnostic performance of the quantitative flow ratio (QFR). BACKGROUND: Functional angiographic assessment of coronary stenoses based on fluid dynamics, such as QFR, constitutes an attractive alternative to fractional flow reserve (FFR). However, it is unknown whether CMD affects the reliability of angiography-based functional indices. METHODS: FFR and the index of microcirculatory resistance (IMR) were measured in 300 vessels (248 patients) as part of a multicenter international registry...

BACKGROUND: Systemic lupus erythematosus (SLE) is associated with enhanced risk of atherosclerotic cardiovascular disease not explained by Framingham risk score (FRS). Immune dysregulation associated to a distinct subset of lupus proinflammatory neutrophils (low density granulocytes; LDGs) may play key roles in conferring enhanced CV risk. This study assessed if lupus LDGs are associated with in vivo vascular dysfunction and inflammation and coronary plaque. METHODS: SLE subjects and healthy controls underwent multimodal phenotyping of vascular disease by quantifying vascular inflammation (18F-fluorodeoxyglucose-PET/CT [18F-FDG-PET/CT]), arterial dysfunction (EndoPAT and cardio-ankle vascular index), and coronary plaque burden (coronary CT angiography)...

PURPOSE: Previous studies have indicated that stent implantation could alter the vessel geometry, which may impact the neointimal healing process. Curvature is an important parameter for evaluating vessel geometry. The purpose of our study was to investigate the relationship between vessel curvature and neointimal healing after stent implantation. METHODS: Fifty-nine patients with acute coronary syndrome (ACS) who underwent stent implantation were enrolled in the study...

Kounis syndrome is defined as the clinical development of acute coronary syndrome caused by the activation of inflammatory cells due to an allergy, hypersensitivity, anaphylaxis, or anaphylactic reaction. Corticosteroids that are used in the treatment of many inflammatory conditions may paradoxically cause allergic reactions and even anaphylaxis. This article is a description of the case of a 52-yearold female patient who had a non-ST elevation myocardial infarction after the administration of triamcinolone that was relieved with antihistaminic treatment...

BACKGROUND: Therapeutic variability not explained by patient clinical characteristics is a potential source of avoidable morbidity and mortality. We aimed to explore regional variability in the management and mortality of patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS). METHODS AND RESULTS: 11,931 NSTE-ACS hospital survivors enrolled in two prospective registries: EPICOR [5625 patients, 555 hospitals, 20 countries in Europe (E) and Latin America (LA), September 2010-March 2011] and EPICOR Asia (6306 patients, 218 hospitals, 8 countries, June 2011-May 2012) were compared among eight pre-defined regions: Northern E (NE), Southern E (SE), Eastern E (EE); Latin America (LA); China (CN), India (IN), South-East Asia (SA), and South Korea, Hong Kong and Singapore (KS)...

We present a case of a 54-year-old male patient who was admitted to our Emergency Department (ED) with localized epigastric pain. Inflammation markers, ultrasound, and CT scan were inconsistent with an initial diagnosis of cholecystitis. However, there was additional evidence of cholecystolithiasis. The ECG showed new anterior biphasic T waves typical for a Wellens' type A ECG. Additionally, the patient had an intermittent left bundle branch block (LBBB). The diagnostic challenges in differentiating possible diagnoses will be described, to which in this case, were either acute cholecystitis or acute coronary syndrome (ACS)...

Case: Circulatory support using veno-arterial extracorporeal membrane oxygenation for aortic disease is conventionally contraindicated. In this case, a 66-year-old man experienced cardiopulmonary arrest caused by acute aortic dissection. When exercising in the gym, he experienced chest discomfort, so the staff immediately called an ambulance. While in the ambulance, he experienced cardiopulmonary arrest. His initial electrocardiogram showed ventricular fibrillation. At the emergency department, we immediately performed extracorporeal cardiopulmonary resuscitation...

Guideline adherence and variation in acute coronary syndrome (ACS) outcomes by race in the modern era of drug-eluting stents (DES) are not well understood. Previous studies also fail to capture rapidly growing minority populations, such as Asians. A retrospective analysis of 689,238 hospitalizations for ACS across all insurance types from 2008 to 2011 from the Healthcare Cost and Utilization Project database was performed to determine whether quality of ACS care and mortality differ by race (white, black, Asian, Hispanic, or Native American), with adjustment for patient clinical and demographic characteristics and clustering by hospital...

This case describes an unusual presentation of prosthetic valve endocarditis: an acute coronary syndrome. A 67-year-old gentleman presented with cardiac sounding chest pain on a background of a short history of night sweats, weight loss and general malaise. Four months previously he had undergone bio-prosthetic aortic valve replacement for severe aortic stenosis and single vessel bypass grafting of the obtuse marginal. Whilst having chest pain his ECG showed infero-lateral ST depression. Early coronary angiography revealed a new right coronary artery lesion that was not present prior to his cardiac surgery...

The role of serum uric acid in coronary artery disease has been extensively investigated. It was suggested that serum uric acid level (SUA) is an independent predictor of endothelial dysfunction and related to coronary artery lesions. However, the relationship between SUA and severity of coronary atherosclerosis evaluated via endothelial dysfunction using peripheral arterial tone (PAT) and the reactive hyperhemia index (RHI) has not been investigated during a first episode of acute coronary syndrome (ACS). The aim of our study was to address this point...

Congenital anomalies of the coronary arteries are a cause of sudden cardiac death. Of the known anatomic variants, anomalous origination of a coronary artery from an opposite sinus of Valsalva (ACAOS) remains a major clinical issue and a challenging condition to treat. Congenital coronary anomalies are likely to be under-recognized, as completing an anatomic assessment in a very large portion of the population would seem unfeasible. However, we present a case report with image of a 49 year old male presented with acute non-ST elevation ACS for which he underwent diagnostic angiography of the coronary system which revealed a common origin of both right and left main coronary artery from right sinus of Valsalva with significant obstructive lesion in the mid segment of right coronary artery...

OBJECTIVE: Protease-activated receptor-1 (PAR1) is classically activated by thrombin and is critical in controlling the balance of hemostasis and thrombosis. More recently, it has been shown that noncanonical activation of PAR1 by matrix metalloprotease-1 (MMP1) contributes to arterial thrombosis. However, the role of PAR1 in long-term development of atherosclerosis is unknown, regardless of the protease agonist. APPROACH AND RESULTS: We found that plasma MMP1 was significantly correlated ( R =0...

BACKGROUND: Readmissions following acute myocardial infarction are associated with poor outcomes and a heavy economic burden. There are few evidence-based data on the characteristics and outcomes of patients readmitted following acute coronary syndrome. We explored the incidence and outcomes of patients readmitted after an acute coronary syndrome in the past decade. METHODS: The study population comprised all acute coronary syndrome patients who were enrolled and prospectively followed up in the biennial Acute Coronary Syndrome Israeli Survey from 2000 to 2013...

OBJECTIVE: Resistin, a cysteine-rich peptide, is associated with atherosclerosis and diabetes. Resistin levels increase corresponding to coronary artery disease (CAD) and heart failure severity. Since resistin level tends to elevate with symptomatic heart failure, it is expected to be associated with left ventricular end-diastolic pressure (LVEDP). However, there is no relevant literature on the relationship between resistin levels and LVEDP. We aimed to evaluate the association between resistin levels and LVEDP, severity of CAD, carotid intima-media thickness (CIMT), and echocardiographic diastolic dysfunction parameters...

Previous studies found that patients with an acute coronary syndrome (ACS) due to occlusion of the left circumflex (LC) coronary artery often present without ST-elevation, leading to a delay in diagnosis and revascularization, a larger infarct size, and a worse prognosis. In this subgroup analysis of the ELISA-3 study (early or late intervention in high-risk non-ST-segment elevation acute coronary syndromes [NSTE-ACS]) incidence, characteristics and prognosis of LC-related NSTE-ACS was investigated, and the outcome of early versus late invasive strategy was compared...
