Sudden cardiac death (SCD) is a tragic event affecting millions of individuals worldwide. Although several studies have investigated the epidemiology of SCD, these studies may have been affected by reporting and referral biases, which are reflected in the very different incidence rates and causes of deaths that have previously been reported. Among SCD victims aged < 36 years, inherited cardiac diseases are well known to play an important role. However, the extent to which inherited cardiac diseases also play a role in SCD victims aged < 50 years has not been completely described...

The objective of the present study was to analyze the causes of sudden death in the general population and in the fraction of the young subjects (below 39 years of age). The results of the original retrospective study were obtained in the course of forensic medical autopsies of the subjects aged below 39 years that had been carried out during a period of 10 years. It was shown that one of the causes behind sudden death among the young subjects is cardiovascular disorders associated with the pre-existing pathological condition in the form of connective tissue dysplasia...

: Aim The aim of the present study was to determine general paediatrician knowledge, practices, and attitudes towards electrocardiogram (ECG) screening in school athletes during pre-participation screening exam (PPSE). METHODS: Paediatricians affiliated with a tertiary children's hospital completed a survey about ECGs for PPSE. RESULTS: In total, 205/498 (41%) responded; 92% of the paediatricians did not include an ECG as part of PPSE; 56% were aware of a case in which a student athlete in their own community had died of sudden unexplained death; 4% had an athlete in their practice die...

Hypertrophic cardiomyopathy is a common genetic disorder with a prevalence of 1:500 in the general population. Amongst a varied spectrum of clinical presentations, the most feared complication of this cardiac disorder is sudden cardiac death. Although only a minority of patients with hypertrophic cardiomyopathy who suffer sudden cardiac death or resuscitated cardiac arrest do so during exercise, strenuous physical activity is regarded as an important trigger for these tragic outcomes. Furthermore, during exercise, patients with hypertrophic cardiomyopathy may develop augmentation of left ventricular outflow tract obstruction, myocardial ischemia, diastolic dysfunction and/or inappropriate vasodilation in non-exercising vascular beds...

Inherited cardiomyopathies have highly variable expression in terms of symptoms, functional limitations, and disease severity. Associated risk of sudden cardiac death is also variable. International guidelines currently recommend restriction of all athletes with cardiomyopathy from participation in competitive sports. While the guidelines are necessarily conservative because predictive risk factors for exercise-triggered SCD have not been clearly identified, the risk is clearly not uniform across all athletes and all sports...

Tee Joo Yeo, Sanjay Sharma
This article summarizes the role of the 12-lead electrocardiogram (ECG) for the clinical care of athletes, with particular reference to the influence of age, gender, ethnicity, and type of sport on the appearance of the ECG, and its role in differentiating physiologic exercise-related changes from pathologic conditions implicated in sudden cardiac death (SCD). The article also explores the potential role of the ECG in detecting athletes at risk of SCD. In addition, the article reviews the evolution of ECG interpretation criteria and emphasizes the limitations of the ECG as well as the potential for future research...

Cardiovascular screening in young athletes is widely recommended and routinely performed prior to participation in competitive sports. While there is general agreement that early detection of cardiac conditions at risk for sudden cardiac arrest and death (SCA/D) is an important objective, the optimal strategy for cardiovascular screening in athletes remains an issue of considerable debate. At the centre of the controversy is the addition of a resting ECG to the standard preparticipation evaluation using history and physical examination...

BACKGROUND: The early ECG repolarization QRS pattern (ERp), with J-point elevation of 0.1 mV in two contiguous inferior and/or lateral leads, can be associated with ventricular arrhythmias among adults. The significance of an ERp in the young is unknown. OBJECTIVE: The purpose of this study was to assess the prevalence of ERp among young patients (pts), describe and correlate the characteristics with clinical presentations and any arrhythmias. METHODS: This was a 1 y retrospective review of ECGs obtained from patients referred specifically for documented arrhythmias, possible arrhythmia-related symptoms or sports clearance...

Nonischemic Left Ventricular Scar (NLVS) is a pattern of myocardial injury characterized by midventricular and/or subepicardial gadolinium hyper enhancement at cardiac magnetic resonance, in absence of significant coronary artery disease. We aimed to evaluate the prevalence of NLVS in juvenile sudden cardiac death and to ascertain its aetiology at autopsy. We examined 281 consecutive cases of sudden death of subjects aged 1 to 35 years of age. NLVS was defined as a thin, grey rim of subepicardial and/or midmyocardial scar in the left ventricular free wall and/or the septum, in absence of significant stenosis of coronary arteries...

Prevention of sudden cardiac death in athletes requires the screening and recognition of pathologies that often remain clinically silent for years until provoked by a physiologic stressor. This can result in the manifestation of disease and even death. Left ventricular non-compaction cardiomyopathy (LVNC), newly classified as a distinct entity arising in the adult population, is a cardiomyopathy that at initial presentation can manifest as a wide spectrum of symptoms from asymptomatic to ventricular arrhythmias, systemic embolism and even sudden cardiac death...

The most effective protocol for cardiovascular screening of competitive athletes remains highly controversial. This study was a prospective, multicenter trial of cardiovascular screening at 35 National Collegiate Athletic Association institutions. Screening included a standardized history and physical examination (PE) as recommended by the American Heart Association and a 12-lead electrocardiogram (ECG) at rest. Centralized electrocardiographic interpretation was provided using the Seattle criteria. Athletes with screening abnormalities underwent additional evaluation directed by the host institution medical team...

There are clear health benefits to exercise; even so, patients with cardiac conditions who engage in exercise and athletic competition may on rare occasion experience sudden cardiac death (SCD). This article reviews the epidemiology and common causes of SCD in specific athlete populations. There is ongoing debate about the optimal mechanism for SCD prevention, specifically regarding the inclusion of the ECG and/or cardiac imaging in routine preparticipation sports evaluation. This controversy and contemporary screening recommendations are also reviewed...

PURPOSE: Sudden cardiac death in young athlete is always tragic. Some international guidelines recommend the realization of an electrocardiogram before practicing competitive sports to carry out the risk of sudden cardiac death due to genetic cardiopathy like QT long syndrome. Unfortunately, the diagnosis can be difficult because intensive sport can increase the QT interval over normal recognized values for sedentary people. Using a QT correction formula free of heart rate appears essential...

Cardiovascular (CV) screening in young athletes remains challenging and a topic of considerable debate. Recent criticisms of ECG screening have perpetuated arguments that ECG screening is neither indicated nor effective by applying outdated incidence data and flawed methodology. In response, this article provides a critical review of the arguments in favour of ECG screening in athletes and the early detection of CV disorders at elevated risk of sudden cardiac death (SCD). Importantly, no study to date has demonstrated that screening by history and physical examination alone is effective in detecting athletes at risk or in preventing SCD...

REVIEW
Peter J Schwartz, Federica Dagradi
Management of survivors of cardiac arrest is largely based on a traditional approach. However, during the past decade, arrhythmias of genetic origin have increasingly been recognized as contributing to many more cases than previously appreciated. This realization is forcing physicians managing the survivors of cardiac arrest also to consider family members. In this Perspectives article, we examine the appropriate management approaches for survivors of cardiac arrests related to channelopathies, cardiomyopathies, or ischaemic heart disease, and for their families...

PURPOSE OF REVIEW: To better understand the risk of sudden death from coronary anomalies. RECENT FINDINGS: Most coronary anomalies are benign, but there are certain coronary anomalies that increase the risk of sudden cardiac death (SCD) in the young, notably anomalous aortic origin of a coronary artery from the wrong sinus. Previously, the risk of SCD attributed to certain coronary anomalies was felt to be quite high, as the risk assessment was based on autopsy series...
