Management and Treatment of Myocarditis in Athletes.

Purpose Of Review: Myocarditis is an inflammation of the myocardium that can often be associated with cardiac dysfunction and arrhythmias, and is even one of the leading causes for sudden cardiac death (SCD) in athletes. This review aims to summarize the current evidence and treatment guidelines for the management of myocarditis in the active population.

Recent Findings: Physical exertion is likely a trigger for dangerous arrythmias and further propagates myocardial damage in athletes with myocarditis.

Myocardial longitudinal strain, fitness, and heart failure risk factors in young adults.

Aims: To investigate the relationship between fitness, heart failure (HF) risk factors (age, blood pressure, and obesity), and global/regional myocardial longitudinal strain in young adults undergoing stress testing.

Methods: Individuals 25-55 years old without any significant medical history, not taking medications, and with a normal maximal stress echocardiogram were eligible. Global and regional longitudinal strain (LS) was evaluated by 2D speckle tracking echocardiography.

Synthetic psychoactive cathinones: hypothermia and reduced lethality compared to methamphetamine and methylenedioxymethamphetamine.

Rationale: Synthetic psychoactive cathinones (SPCs) are drugs with psychostimulant and entactogenic properties like methamphetamine (MA) and 3,4-methylenedioxymethamphetamine (MDMA). Despite clinical reports of human overdose, it remains to be determined if SPCs have greater propensity for adverse effects than MA or MDMA.

Objectives: To determine whether the SPCs cathinone (CAT), methcathinone (MCAT), mephedrone (MMC), and methylenedioxypyrovalerone (MDPV) have lower LD50 values than MA or MDMA.

The effects of physical activity on cancer prevention, treatment and prognosis: A review of the literature.

Introduction: The World Health Organization has reported that approximately 35% of cancer-related deaths are attributed to modifiable risk factors. Among the most important risk factors amenable to modification are obesity and lack of physical activity. The purpose of this article is to review the current evidence of the benefits of physical activity in various types of cancer.

Developmental effects of trichloroacetate in Zebrafish embryos: Association with the production of superoxide anion.

To assess the developmental toxicity of trichloroacetate (TCA), zebrafish embryos were exposed to 8 to 48 mM of TCA and evaluated for developmental milestones from 8- to 144-hour postfertilization (hpf). All developmental toxicities are reported in this paper. Embryos were found to have developed edema in response to 16 to 48 mM of TCA exposure at 32- to 80-hpf, experienced delay in hatching success in response to 24 to 48 mM at 80-hpf.

One-year experience with ex vivo lung perfusion: Preliminary results from a single center.

Objective: To enlarge the donor pool for lung transplantation, an increasing number of extended criteria donor lungs are used. However, in more than 50% of multi-organ donors the lungs are not used. Ex vivo lung perfusion offers a unique possibility to evaluate and eventually recondition the injured donor lungs.

Effect of high-dose oral multivitamins and minerals in participants not treated with statins in the randomized Trial to Assess Chelation Therapy (TACT).

Importance: In a prespecified subgroup analysis of participants not on statin therapy at baseline in the TACT, a high-dose complex oral multivitamins and multimineral regimen was found to have a large unexpected benefit compared with placebo. The regimen tested was substantially different from any vitamin regimen tested in prior clinical trials.

Objective: To explore these results, we performed detailed additional analyses of participants not on statins at enrollment in TACT.

Left Atrial Size and Heart Failure Hospitalization in Patients with Diastolic Dysfunction and Preserved Ejection Fraction.

Context: Heart failure with preserved ejection fraction (HFpEF) is a clinical syndrome associated with diastolic function abnormalities. It remains unclear which factors, if any, can predict the transition from asymptomatic diastolic dysfunction to an overt symptomatic phase.

Materials And Methods: Patients hospitalized with suspected heart failure between January 2012 and November 2014 with a transthoracic echocardiogram demonstrating preserved systolic function were screened ( = 425).

Electrocardiographic Criteria for the Diagnosis of Left Ventricular Hypertrophy.

Background: Current electrocardiographic (ECG) criteria for the diagnosis of left ventricular hypertrophy (LVH) have low sensitivity.

Objectives: The goal of this study was to test a new method to improve the diagnostic performance of the electrocardiogram.

Methods: The study was divided into 2 groups, a test and a validation cohort.

Simplified prediction of postoperative cardiac surgery outcomes with a novel score: R2CHADS2.

Objective: To compare the accuracy of R2CHADS2, CHADS2, and CHA2DS2-VASc scores vs the Society of Thoracic Surgeons (STS) score as predictors of morbidity and mortality after cardiovascular surgery.

Methods: All patients who underwent cardiothoracic surgery at our institution from January 2008 to July 2013 were analyzed. Only those patients who fulfilled the criteria for STS score calculation were included.

Edetate Disodium-Based Treatment for Secondary Prevention in Post-Myocardial Infarction Patients.

An abundance of data, known for decades, is available linking metals, such as lead and cadmium, with cardiovascular disease. However, the idea that these toxic metals could be a modifiable risk factor for atherosclerosis did not become apparent clinically until the completion of the Trial to Assess Chelation Therapy in 2012. This pivotal study was the first double-blind, randomized, controlled trial of its kind to demonstrate a clear improvement in cardiovascular outcomes with edetate disodium therapy in a secondary prevention, post-myocardial infarction population.

An example of the deleterious effects of right ventricular apical pacing.

Pacemaker implantation remains the mainstay of treatment in patients with symptomatic sinus node disease or severe heart block. Despite the dramatic benefits of this therapy, a high burden of ventricular pacing is known to have its disadvantages. Reported is the case of an 85-year-old woman with a history of sick sinus syndrome who presented with congestive heart failure after her atrioventricular sequential pacemaker defaulted to ventricular pacing mode as a result of battery depletion.

Usefulness of the CHA2DS2VASc score to predict postoperative stroke in patients having cardiac surgery independent of atrial fibrillation.

Despite its association with cardioembolic stroke, atrial fibrillation (AF) appears to be inconsistent as a risk factor for postoperative strokes in patients who underwent cardiac surgery. Furthermore, the relation between AF and the CHA2DS2VASc score has not been definitively established with respect to postoperative stroke. We retrospectively analyzed the records of all cardiac surgery performed at our institution between January 2008 and July 2013.

Pleiotropic effects of the 3-hydroxy-3-methylglutaryl-CoA reductase inhibitors in pulmonary diseases: a comprehensive review.

The 3-hydroxy-3-methylglutaryl-CoA reductase inhibitors (statins) are used extensively in the treatment of hyperlipidemia. They have also demonstrated a secondary benefit in a variety of other disease processes, actions which are known as pleiotropic effects. Review of the current pulmonary literature suggests a potential advantage of statin usage in a variety of pulmonary conditions.

The use of nitrates in the prevention of contrast-induced nephropathy in patients hospitalized after undergoing percutaneous coronary intervention.

Contrast-induced nephropathy (CIN) is a significant cause of morbidity and mortality and effective strategies for its prevention are greatly needed. The purpose of this retrospective, single-center study was to investigate whether nitrate use during percutaneous coronary artery intervention reduces the incidence of CIN. Chart review of all individuals who underwent percutaneous coronary intervention (PCI) from April 2010 to March 2011 was done.

Cardiac angiofibroma: a rare primary cardiac tumor.

Cardiac angiofibromas are rare tumors. We report a patient with an angiofibroma of the mitral valve and discuss the management of these tumors.

Valve configuration determines long-term results after repair of the bicuspid aortic valve.

Background: Reconstruction of the regurgitant bicuspid aortic valve has been performed for >10 years, but there is limited information on long-term results. We analyzed our results to determine the predictors of suboptimal outcome.

Methods And Results: Between November 1995 and December 2008, 316 patients (age, 49±14 years; male, 268) underwent reconstruction of a regurgitant bicuspid aortic valve.

Aortic root and cusp configuration determine aortic valve function.

Objective: Normalisation of aortic root and cusp configuration is a prerequisite for successful aortic valve repair (AVR). Using transthoracic echocardiography, we studied aortic root dimensions relative to body size in normal subjects and AVR patients.

Methods: Aortic roots of healthy volunteers (n=130, age 27.
