The paper gives an original algorithm for the management of patients with stable coronary artery disease, preserved/moderately reduced left ventricular systolic function, and high-grade ventricular arrhythmias from the first registration of the latter to the choice of treatment policy. Great attention is paid to the assessment of a private clinical case, by determining the nature of arrhythmias, and to the involvement of autonomic regulation in the genesis of ventricular arrhythmias. The importance of topical diagnosis of ventricular arrhythmias and identification of psychological disorders is emphasized...

BACKGROUND: Intensive selection has resulted in increased growth rates and muscularity in broiler chickens, in addition to adverse effects, including delayed organ development, sudden death syndrome, and altered metabolic rates. The biological mechanisms underlying selection responses remain largely unknown. Non-artificially-selected indigenous Chinese chicken breeds display a wide variety of phenotypes, including differential growth rate, body weight, and muscularity. The Wuding chicken breed is a fast growing large chicken breed, and the Daweishan mini chicken breed is a slow growing small chicken breed...

Aims: The arrhythmic risk stratification of arrhythmogenic right ventricular cardiomyopathy (ARVC) remains controversial. We evaluated the long-term distribution of life-threatening arrhythmic events assessing the impact of periodical risk reassessment. Methods and results: Ninety-eight ARVC patients with no previous major ventricular arrhythmias were retrospectively analysed. Patients were assessed at baseline, at 22 [inter-quartile range (IQR) 16-26], 49 (IQR 41-55) and 97 months (IQR 90-108)...

OBJECTIVE: To review studies on structural pulmonary and cardiac changes in SUDEP cases as well as studies showing pulmonary or cardiac structural changes in living epilepsy patients. METHODS: We conducted electronic literature searches using the PubMed database for articles published in English, regardless of publication year, that included data on cardiac and/or pulmonary structural abnormalities in SUDEP cases or in living epilepsy patients during the postictal period...

Replicative aging has been demonstrated in asymmetrically dividing unicellular organisms, seemingly caused by unequal damage partitioning. Although asymmetric segregation and inheritance of potential aging factors also occur in symmetrically dividing species, it nevertheless remains controversial whether this results in aging. Based on large-scale single-cell lineage data obtained by time-lapse microscopy with a microfluidic device, in this report, we demonstrate the absence of replicative aging in old-pole cell lineages of Schizosaccharomyces pombe cultured under constant favorable conditions...

A recent article by Farrell et al. characterizes the phenomenon, mechanisms, and treatment of a local and severe hypoperfusion/hypoxia event that occurs in brain regions following a focal seizure. Given the well-established role of cerebral ischemia/hypoxia in brain damage and behavioral dysfunction in other clinical settings (e.g., stroke, cerebral vasospasm), we put forward a new theory: postictal hypoperfusion/hypoxia is responsible for the negative consequences associated with seizures. Fortunately, inhibition of two separate molecular targets, cyclooxygenase-2 (COX-2) and l-type calcium channels, can prevent the expression of postictal hypoperfusion/hypoxia...

Background: Implantable cardioverter-defibrillators (ICDs) have a role in preventing cardiac arrest in patients at risk for life-threatening ventricular arrhythmias. Purpose: To compare ICD therapy with conventional care for the primary prevention of death of various causes in adults with ischemic or nonischemic cardiomyopathy. Data Sources: MEDLINE, Cochrane Central Register of Controlled Trials, Google Scholar, and EMBASE databases, as well as several Web sites, from 1 April 1976 through 31 March 2017...

A survey of 146 pediatric care providers (PCPs) revealed that 75.3% were unaware that children with epilepsy were at risk of death, specifically from sudden unexpected (or unexplained) death in epilepsy (SUDEP). PCPs assume that the treating neurologist discusses these risks. Increasing PCPs' knowledge of SUDEP will help address the care gap related to informing families about SUDEP.

Cardiovascular diseases are responsible for many deaths in our western societies. Practice of sport activities can decrease their occurrence and improve the prognosis of the patients already affected. The practice of a sport, however, presents an increased cardiovascular risk during its realization (sudden death, myocardial infarction, etc.). An assessment of the risk of complication is necessary before allowing patients with ischemic heart disease to practice a sport activity. Sport activities in competitions are discouraged for most patients, but for the majority, recreational activities should be encouraged...

BACKGROUND: Complex cardiac rhythm management device (CRMD) therapy provides an important treatment option for people at risk of sudden cardiac death. Despite the survival benefit, device implantation is associated with significant physical and psychosocial concerns presenting considerable challenges for the decision-making process surrounding CRMD implantation for patients and physicians. AIMS: The purpose of this scoping review was to explore what is known about how adult (>16 years) patients make decisions regarding implantation of CRMD therapy...

Sudden cardiac death (SCD) in hypertrophic cardiomyopathy (HCM) is caused by ventricular tachyarrhythmia that can be effectively treated by implantable cardioverter defibrillator (ICD) therapy. We report of a 28-year-old man with HCM and a dual chamber ICD, originally implanted for primary prevention of SCD, (programmed to AAI(R)-DDD(R); managed ventricular pacing (MVP) mode, Medtronic Inc. St Paul, MN USA). He presented with recurrent ICD shocks due to ventricular fibrillation (VF) despite antiarrhythmic therapy...

Patients with diabetes mellitus, prior myocardial infarction, older age, and a relatively preserved left ventricular ejection fraction remain at risk for sudden cardiac death that is potentially amenable by the subcutaneous implantable cardioverter defibrillator with a good risk-benefit profile. The launched MADIT S-ICD study is designed to test the hypothesis that post-myocardial infarction diabetes patients with relatively preserved ejection fraction of 36%-50% will have a survival benefit from a subcutaneous implantable cardioverter defibrillator...

Since its recognition as a clinical entity in 1992, the Brugada Syndrome (BrS), a hereditary disease characterized by a typical electrocardiogram (ECG) pattern potentially predisposing to sudden cardiac death (SCD), has attracted the attention of many physicians for its circadian pattern of ventricular arrhythmias (VA), mostly occurring at rest. Exercise may potentially worsen the ECG abnormalities in BrS patients, resulting in higher peak J-point amplitudes during the vasovagal reaction of the recovery period, possibly leading to an increased risk of cardiac events...

Arrhythmogenic right ventricular cardiomyopathy/dysplasia is an inherited autosomal dominant pathology with an estimated prevalence of 1:2,500 to 1:5,000, being higher in males (3:1). It is characterized histologically by replacement of cardiomyocytes by fibro-adipose tissue, which predisposes to ventricular arrhythmias, right ventricular failure, and sudden cardiac death. The main goal of treatment is to reduce the risk of sudden death and improve the quality of life of patients. We present the case of a 23 year old woman whose clinical symptoms started with palpitations, chest pain with physical activity, syncope and headache 6 years ago during her first pregnancy...

INTRODUCTION: Isolated ventricular premature beats (VPBs) are commonly found during pre-participation screening in athletes. Currently the debate about the role of detraining in reducing the number of VPBs is still open. This study evaluated the arrhythmic risk in a population of young competitive athletes who showed VPBs during eligibility evaluation and that did not undergo detraining but continued practicing competitive sports. METHODS: 3746 consecutive subjects underwent pre-participation screening...
