Although few doubts remain that physical exercise should be widely promoted for maintenance of health and fitness, the risk of adverse events such as sudden death (especially due to cardiac causes, i.e., sudden cardiac death [SCD]) during exercise remains tangible. The overall risk of sudden death in athletes is relatively low (i.e., usually comprised between 0.1 and 38/100,000 person-years), and globally comparable to that of the general population. However, up to 20% of all sudden death cases are still recorded while exercising...

Background: Female firefighters are in the minority in the Québec firefighter population and worldwide. To our knowledge, no study has focused on cardiovascular risk factors in female firefighters, and further research in this area is needed to evaluate and reduce the risk of on-duty sudden cardiac death. Aims: To evaluate the prevalence of cardiovascular disease (CVD) risk factors in female firefighters in Québec. Methods: A cross-sectional study using an online questionnaire to evaluate lifestyle and CVD risk factors and symptoms...

OBJECTIVES: Intense exercise elevates all heart chambers' dimensions, left ventricular mass (LV mass), and left ventricular mass index (LV mass index). The relationship between increased ventricular arrhythmias and sudden cardiac death with LV dilatation and elevated LV mass has been previously demonstrated. We investigated whether sports-related LV dilatation and elevated LV mass and LV mass index cause an increase in ventricular repolarization heterogeneity. PATIENTS AND METHODS: This prospective observational study recruited 565 participants...

Sickle cell trait has long been considered a benign condition but continues to be the leading cause of death in young African Americans in military basic training and civilian organized sports. There continues to be a great deal of controversy surrounding sickle cell trait and its association with exercise-related morbidity and sudden death. Even though sickle cell trait has a high prevalence among African Americans, many clinicians believe the potential adverse consequences should have been mitigated by actions such as universal screening in the USA at birth for sickle hemoglobin, National Collegiate Athletic Association (NCAA) rule changes, and changes in the US Military boot camp system...

BACKGROUND: The development of athlete-specific electrocardiogram (ECG) interpretation standards, along with recent rates of sudden cardiac death (SCD) in athletes being higher than previously estimated, has heightened the debate in the sports medicine community regarding cardiovascular screening of the college athlete, including whether certain high-risk subsets, such as male basketball athletes, should undergo more intensive screening. HYPOTHESIS: ECG and/or echocardiography screening in National Collegiate Athletic Association Autonomous 5 Division I (A5DI) schools will be more common than previous reports, and there will be more frequent use of noninvasive cardiac screening for men's basketball players than the general athlete population...

Sudden cardiac death (SCD) is the non-traumatic death, due to loss of heart function that occurs suddenly and unexpectedly within 6 hours of a previously normal state of health. It is related to intense competitive sports promoting ventricular tachycardia (VT)/ventricular fibrillation (VF) in the presence of underlying abnormal substrate. A serial evaluation of cardiac physiologic changes taking place during training will allow the better understanding of athlete's heart and will facilitate its discrimination from other gray-zone cardiomyopathies...

Sudden cardiac death (SCD) in an apparently healthy individual is a tragedy. It is important to identify the cause of death and to prevent SCD in potentially at-risk family members. Inherited primary arrhythmia disorders are associated with exercise-related SCD. Despite the well-known benefits of exercise, exercise restriction has been a historical mainstay of therapy for these conditions. However, since familiarity with inherited arrhythmia conditions has increased and patients are often children and young adults, it is necessary to reassess the treatment guidelines regarding exercise constraints...

Despite the cardiovascular benefits of regular sports, sudden cardiac arrest (SCA) risk is increased during or shortly after exercise. Association with coronary artery disease (CAD) has been described in small studies, mainly autopsic with potential bias given the high sports-related SCA survival, and focusing on young competitive athletes, whereas sports-related SCA occurs mostly in recreational athletes.1-5 Through the Paris Sudden Death Expertise Center prospective registry that includes all SCAs in Paris and suburbs since May 2011, we performed the first broad comprehensive CAD description in sports-related SCAs, with a comparison with matched non-sports-related SCAs...

PURPOSE: Commotio cordis is sudden cardiac death caused by a relatively innocent blow to the left chest wall. Adolescents account for the majority of the cases; whether this is due to the higher frequency of adolescents playing ball sports or whether there is some maturational reduction of risk is not known. METHODS: In a swine model of commotio cordis, the effect of body weight/size (directly related to age) to the susceptibility of chest impact induced ventricular fibrillation (VF) is examined...

Sudden cardiac death (SCD) in an athlete is a rare but tragic event. In view of this, pre-participation cardiac screening is mandatory across many sporting disciplines to identify those athletes at risk. Echocardiography is a primary investigation utilized in the pre-participation setting and in 2013 the British Society of Echocardiography and Cardiac Risk in the Young produced a joint policy document providing guidance on the role of echocardiography in this setting. Recent developments in our understanding of the athlete's heart and the application of echocardiography have prompted this 2018 update...

Physical activity comprises all muscular activities that require energy expenditure. Regular sequence of structured and organized exercise with the specific purpose of improving wellness and athletic performance is defined as a sports activity.Exercise can be performed at various levels of intensity and duration. According to the social context and pathways, it can be recreational, occupational, and competitive. Therefore, the training burden varies inherently and the heart adaptation is challenging.Although a general agreement on the fact that sports practice leads to metabolic, functional and physical benefits, there is evidence that some athletes may be subjected to adverse outcomes...

Despite the fact that sports organizations and legislators have introduced various mechanisms to discourage athletes from using performance and appearance enhancing substances a high percentage of athletes admits to their unabated application. In competitive athletics, bodybuilding and in recreational sports anabolic androgenic steroids (AAS) continue to be the substances most abused. This review summarizes the side effects of AAS abuse on organs and system functions in both sexes. High doses of AAS cause a significant increase of erythrocytes und haemoglobin concentration, which may lead to thromboembolism, intracardiac thrombosis and stroke...

The annual incidence of sudden cardiac death (SCD) in athletes is significantly lower than the general population. However, when SCD occurs in an athlete during sporting event or training, it sends shockwaves in the society and raises questions about cardiovascular effects of sports and exercise. This document reviews the causes and mechanism of SCD in sports and exercise in young and older athletes. In the Indian context, we suggest a 'pre-participation screening' of young and older athletes and consider a 'supervised, graded exercise regime' for the uninitiated, older sports participant...

Competitive sports activity is associated with an increased risk of sudden cardiovascular death in adolescents and young adults with inherited cardiomyopathies. Many young subjects aspire to continue competitive sport after a diagnosis of cardiomyopathy and the clinician is frequently confronted with the problem of eligibility and the request of designing specific exercise programs. Since inherited cardiomyopathies are the leading cause of sudden cardiovascular death during sports performance, a conservative approach implying disqualification of affected athletes from most competitive athletic disciplines is recommended by all the available international guidelines...

Professional society recommendations to decrease sudden cardiac death in athletes, including eligibility requirements with disqualification for athletes with diagnosed disease as well as preparticipation screening and emergency preparedness, were updated in 2015. The update includes new sections on aortic disease, channelopathies, and sickle cell trait, as well as a change in format from the previous binary yes/no format to the more nuanced and contemporary "class and level of evidence" format. Eighty-four of the 246 recommendations now carry Class II designation-"reasonable," or "may be considered...

Exercise-associated benefits on the cardiovascular systems are well established. Although exercise-associated sudden cardiac death is rare, most deaths in young athletes are due to hereditary or congenital cardiac diseases. Athletic adaptation itself is associated with several structural changes that overlap those observed in individuals with cardiomyopathies, often leading to dilemmas for the clinician regarding life-changing decisions including advice against competitive sports participation. Cardiac magnetic resonance plays an increasingly important role in helping to establish an accurate diagnosis in these individuals...

Sudden cardiac arrest or death (SCA/SCD) in athletes has a low event rate. Pre-participation or eligibility screening is a widely accepted method of primary prevention of SCA/SCD in athletes. Most European countries and international sports governing bodies perform ECG-inclusive screening. However, implementation of a resting 12-lead ECG in pre-participation or eligibility cardiac screening is still a topic of debate. Recently, the 'International recommendations for electrocardiographic interpretation in athletes' was published in three leading international medical journals...
