Background: Recent-onset atrial fibrillation (AF) is a frequent cause for presentation to the emergency department. Recent studies proposed that the addition of biomarker information might improve the prediction of clinical outcomes by enabling identification of patients at high risk. Aim: We aimed to examine the role of cardiac troponin I as a predictor of clinical outcome in patients with first episode acute atrial fibrillation. Design: : Patients, 18 years or older, presenting to our hospital with a primary diagnosis of first episode acute atrial fibrillation were included in this retrospective study...

Aims: Monocytes/macrophages response plays a key role in post-infarction inflammation that contributes greatly to post-infarction ventricular remodeling and cardiac rupture. Therapeutic targeting of the GABAA receptor, which is enriched in monocytes/macrophages but not expressed in the myocardium, may be possible after myocardial infarction. Methods and results: After MI was induced by ligation of the coronary artery, C57BL/6 mice were intraperitoneally administered with one specific agonist or antagonist of the GABAA receptor (topiramate or bicuculline), in the setting of presence or depletion of monocytes/macrophages...

Cardiac disease is the leading cause of death in the developed world. Ventricular arrhythmias associated with myocardial ischaemia and/or infarction are a major contributor to cardiovascular mortality, and require improved prevention and treatment. Drugs, devices, and radiofrequency catheter ablation have made important inroads, but have significant limitations ranging from incomplete success to undesired toxicities and major side effects. These limitations derive from the nature of the intervention. Drugs are frequently ineffective, target the entire heart, and often do not deal with the specific arrhythmia trigger or substrate...

OBJECTIVE: Severe hypercalcemia is often considered an emergency because of a potential risk of cardiac arrest or coma. However, there is little evidence to support this. The aim of our study was to assess whether severe hypercalcemia (Ca>4 mmol/l or 16 mg/dl) was associated with immediately life-threatening cardiac arrhythmias or neurological complications in patients admitted to the Emergency Department (ED). METHODS: A retrospective observational study was carried out over a 5-year period (2008-2012)...

OBJECTIVE: To compare clinical outcomes after laparoscopic lavage (LL) or colonic resection (CR) for purulent diverticulitis. BACKGROUND: Laparoscopic lavage has been suggested as an alternative treatment for traditional CR. Comparative studies to date have shown conflicting results. METHODS: Electronic searches of Embase, Medline, Web of Science, and Cochrane databases were performed. Weighted mean differences (WMD) were calculated for effect size of continuous variables and pooled odds ratios (POR) calculated for discrete variables...

Background -Current surgical and medical treatment options for severe tricuspid regurgitation (TR) are limited and additional interventional approaches are required. In the present observational study, the safety and feasibility of transcatheter repair of chronic severe TR with the MitraClip system were evaluated. In addition, the effects on clinical symptoms were assessed. Methods -Patients with heart failure symptoms and severe TR on optimal medical treatment were treated with the MitraClip system. Safety, defined as periprocedural adverse events such as death, myocardial infarction, stroke, or cardiac tamponade, and feasibility, defined as successful implantation of one or more MitraClip devices and reduction of TR by at least one grade, were evaluated before discharge and after 30 days...

Anthracycline cardiotoxicity remains a serious problem in paediatric and adult cancer survivors, and the advancement of cardio-oncology is a necessary step for an effective care of the patients that experience adverse cardiovascular effects. In this review, we discuss the multiple instruments used by clinicians that constitute the current strategies for primary and secondary prevention aiming at contrasting the onset of early and late doxorubicin-induced cardiotoxic events. The importance of early detection of cardiotoxicity and the following pharmacological therapy has been acknowledged with the emphasis put on impaired diastolic function, an increasingly recognized precocious sign of doxorubicin cardiotoxicity with an emerging scientific and clinical interest...

BACKGROUND: The relations of elevated N-terminal pro-brain natriuretic peptide (NT-pro-BNP) and cardiac ischemia in hypertrophic cardiomyopathy (HCM) patients is uncertain. Therefore we designed the study with the following aims: (1) to analyze plasma concentrations of NT-pro-BNP in various subsets of HCM patients; (2) to reveal the correlations of NT-pro-BNP, myocardial ischemia, and diastolic dysfunction; (3) to assess predictors of the elevated plasma levels of NT-pro-BNP. METHODS AND RESULTS: In 61 patients (mean age 48...

REVIEW
Brian F Wall, Kirk Magee, Samuel G Campbell, Peter J Zed
BACKGROUND: Procedural sedation and analgesia (PSA) is used frequently in the emergency department (ED) to facilitate painful procedures and interventions. Capnography, a monitoring modality widely used in operating room and endoscopy suite settings, is being used more frequently in the ED setting with the goal of reducing cardiopulmonary adverse events. As opposed to settings outside the ED, there is currently no consensus on whether the addition of capnography to standard monitoring modalities reduces adverse events in the ED setting...

Speckle tracking echocardiography (STE) has emerged as a novel angle-independent modality in assessing myocardial velocity, deformation, and strain. Its role in assessing change before and after aortic valve replacement in patients with aortic stenosis (AS) has recently generated interest. This review summarizes the practical utility and clinical implications of myocardial deformation by STE after surgical or transcatheter aortic valve replacement (TAVR). Overall, atrial strain and ventricular strain as measured by STE improve after surgical and transcatheter aortic intervention in short- and long-term follow-up with evidence of a more pronounced acute improvement in patients who undergo TAVR...

BACKGROUND: Cardiotoxicity is a documented complication of Crotalinae envenomation. Reported cardiac complications following snake envenomation have included acute myocardial infarction, electrocardiogram abnormalities and arrhythmias. Few reports exist describing arrhythmia induced by viper envenomation and to our knowledge none describe arrhythmia induced by Crotalinae envenomation. This report concerns the first known case of atrial fibrillation precipitated by rattlesnake bite. CASE PRESENTATION: A 73-year-old Caucasian man with a past medical history of hypertension, hyperlipidemia, type 1 diabetes mellitus, and a baseline first-degree atrioventricular block presented to the emergency department following a rattlesnake bite to his left lower leg...

BACKGROUND Heparin-induced thrombocytopenia (HIT) is a rare but life-threatening complication of heparin administration. It can present a major clinical dilemma for physicians caring for patients requiring life-saving urgent or emergent cardiac surgery. Studies have been published examining the use of alternative anticoagulants for patients undergoing cardiopulmonary bypass (CPB), however, evidence does not clearly support any particular approach. Presently, there are no large-scale, prospective randomized studies examining the impact of alternative anticoagulants on clinical outcomes for HIT-positive patients requiring cardiac surgery...

BACKGROUND: For patients with the Fontan circulatory arrangement, angiotensin-converting enzyme inhibition, guanylate cyclase activation, phosphodiesterase 5 inhibition, and endothelin receptor antagonism have so far resulted in little or no improvement in [Formula: see text] or peak cardiac index (CI), suggesting that our understanding of the factors that most impact the exercise hemodynamics is incomplete. METHODS: To facilitate comparisons with clinical reports of the exercise performance of preadolescent Fontan patients, we rescaled our previously reported computational models of a two-year-old normal child and similarly aged Fontan patient, extended our Fontan model to capture the nonlinear relationship between flow and resistance quantified from previous computational fluid dynamic analyses of the total cavopulmonary connection (TCPC), and added respiration as well as skeletal muscle contraction...

BACKGROUND: Mortality associated with correction of type IV total anomalous pulmonary venous connection (TAPVC) is generally reported in combination with other anatomic types. The objective of this study is to review surgical outcomes associated with the repair of type IV TAPVC by analyzing a multi-institutional cohort specific for this group. We also analyze patient-specific variables that may contribute to poor operative outcomes. METHODS: A retrospective review of the Pediatric Cardiac Care Consortium (PCCC) registry identified patients who underwent repair of type IV TAPVC between 1982 and 2007...

BACKGROUND: The Adult Congenital Heart Association (ACHA) is dedicated to supporting patients with congenital heart disease. To guide patients to qualified providers and programs, it maintains a publicly accessible directory of dedicated adult congenital cardiac programs. We analyzed the directory in 2006 and 2015, aiming to evaluate the growth of the directory as a whole and to evaluate the growth of individual programs within the directory. We also hope this raises awareness of the growing opportunities that exist in adult congenital cardiology and cardiac surgery...

Sudden cardiac death (SCD) is the leading cause of mortality in athletes during sport. A variety of mostly hereditary, structural, or electrical cardiac disorders are associated with SCD in young athletes, the majority of which can be identified or suggested by abnormalities on a resting 12-lead electrocardiogram (ECG). Whether used for diagnostic or screening purposes, physicians responsible for the cardiovascular care of athletes should be knowledgeable and competent in ECG interpretation in athletes. However, in most countries a shortage of physician expertise limits wider application of the ECG in the care of the athlete...
