Performance of the American Heart Association ( AHA ) 14-Point Evaluation Versus Electrocardiography for the Cardiovascular Screening of High School Athletes: A Prospective Study

Assessment of cardiovascular risk and physical activity: the role of cardiac-specific biomarkers in the general population and athletes

The first part of this Inter-Society Document describes the mechanisms involved in the development of cardiovascular diseases, particularly arterial hypertension, in adults and the elderly. It will also examine how consistent physical exercise during adolescence and adulthood can help maintain blood pressure levels and prevent progression to symptomatic heart failure. The discussion will include experimental and clinical evidence on the use of specific exercise programs for preventing and controlling cardiovascular diseases in adults and the elderly. In the second part, the clinical relevance of cardiac-specific biomarkers in assessing cardiovascular risk in the general adult population will be examined, with a focus on individuals engaged in sports activities. This section will review recent studies that suggest a significant role of biomarkers in assessing cardiovascular risk, particularly the presence of cardiac damage, in athletes who participate in high-intensity sports. Finally, the document will discuss the potential of using cardiac-specific biomarkers to monitor the effectiveness of personalized physical activity programs (Adapted Physical Activity, APA). These programs are prescribed for specific situations, such as chronic diseases or physical disabilities, including cardiovascular diseases. The purposes of this Inter-Society Document are the following: 1) to discuss the close pathophysiological relationship between physical activity levels (ranging from sedentary behavior to competitive sports), age categories (from adolescence to elderly age), and the development of cardiovascular diseases; 2) to review in detail the experimental and clinical evidences supporting the role of cardiac biomarkers in identifying athletes and individuals of general population at higher cardiovascular risk; 3) to stimulate scientific societies and organizations to develop specific multicenter studies that may take into account the role of cardiac biomarkers in subjects who follow specific exercise programs in order to monitor their cardiovascular risk.

Palpitations in athletes: diagnosis, workup and treatment

Palpitations are a common reason for athletes to seek medical care. Although often benign, palpitations may serve as a harbinger for underling cardiac pathology. Given the unique challenges in this population, this review will serve to discuss the basic underlying pathophysiology, which may predispose athletes to palpitations. In addition, we will review the aetiologies, diagnostic evaluation, management and counselling strategies for some of the most common diagnoses seen in athletes.

2024 HRS expert consensus statement on arrhythmias in the athlete: Evaluation, treatment, and return to play

Youth and adult participation in sports continues to increase, and athletes may be diagnosed with potentially arrhythmogenic cardiac conditions. This international multidisciplinary document is intended to guide electrophysiologists, sports cardiologists, and associated health care team members in the diagnosis, treatment, and management of arrhythmic conditions in the athlete with the goal of facilitating return to sport and avoiding the harm caused by restriction. Expert, disease-specific risk assessment in the context of athlete symptoms and diagnoses is emphasized throughout the document. After appropriate risk assessment, management of arrhythmias geared toward return to play when possible is addressed. Other topics include shared decision-making and emergency action planning. The goal of this document is to provide evidence-based recommendations impacting all areas in the care of athletes with arrhythmic conditions. Areas in need of further study are also discussed.

Can we screen for heart disease in children at public health centres? A multicentre observational study of screening for heart disease with a risk of sudden death in children

Sudden cardiac death in children is a rare event, but of great social significance. Generally, it is related to heart disease with a risk of sudden cardiac death (SCD), which may occur with cardiovascular symptoms and/or electrocardiographic markers; thus, a primary care paediatrician (PCP) could detect them. Therefore, we proposed a study that assesses how to put into practice and conduct a cardiovascular assessment within the routine healthy-child check-ups at six and twelve years of age; that reflects cardiovascular signs and symptoms, as well as the electrocardiographic alterations that children with a risk of SCD in the selected population present; and that assesses the PCP's skill at electrocardiogram (ECG) interpretation. In collaboration with PCPs, primary care nurses, and paediatric cardiologists, an observational, descriptive, multicentre, cross-sectional study was carried out in the Balearic Islands (Spain), from April 2021 to January 2022, inclusive. The PCPs gathered patient data through forms (medical record, electrocardiogram, and physical examination) and sent them to the investigator, together with the informed consent document and electrocardiogram. The investigator passed the electrocardiogram on to the paediatric cardiologists for reading, in an identical form to those the paediatricians had filled in. The variables were collected, and a descriptive analysis performed. Three paediatric cardiologists, twelve PCPs, and nine nurses from seven public health centres took part. They collected the data from 641 patients, but 233 patients did not participate (in 81.11% due to the PCP's workload). Therefore, the study coverage was around 64%, representing the quotient of the total number of patients who participated, divided by the total number of patients who were eligible for the study. We detected 30 patients with electrocardiographic alterations compatible with SCD risk. Nine of these had been examined by a paediatric cardiologist at some time (functional murmur in 8/9), five had reported shortness of breath with exercise, and four had reported a family history of sudden death. The physical examination of all the patients whose ECG was compatible with a risk of SCD was normal. Upon analysing to what extent the ECG results of the PCP and the paediatric cardiologist agreed, the percentage of agreement in the final interpretation (normal/altered) was 91.9%, while Cohen's kappa coefficient was 31.2% (CI 95%: 13.8-48.6%). The sensitivity of the ECG interpretation by the PCP to detect an ECG compatible with a risk of SCD was 29% and the positive predictive value 45%.     Conclusions: This study lays the foundations for future SCD risk screening in children, performed by PCPs. However, previously, it would be important to optimise their training in reading and interpreting paediatric ECGs. What is Known: • In Spain at present, there is a programme in place to detect heart disease with a risk of sudden death [1], but it targets only children who are starting on or are doing a physical activity as a federated sport. Implementing such screening programmes has proven effective in several countries [2]. However, several studies showed that the incidence of sudden cardiac death is no higher in children competing in sport activities than in those who do not do any sport [3]. This poses an ethical conflict, because at present, children who do not do any federated sport are excluded from screening. According to the revised literature, so far, only in two studies did they screen the child population at schools, and in both, they successfully detected patients with heart disease associated to the risk of sudden death [4, 5]. We have found no studies where the screening of these features was included within the routine healthy-child check-ups by primary care paediatricians. What is New: • We did not know whether-in our setting, at present-the primary care paediatrician could perform a screening method within the routine healthy-child check-ups, in order to detect presumably healthy children at risk of sudden cardiac death, as they present one of the SCD risks. In this regard, we proposed our project: to assess how to put into practice and conduct a cardiovascular assessment via SCD risk screening in the healthy child population by primary care paediatricians and appraise primary care paediatricians' skills in identifying the electrocardiographic alterations associated with SCD risk. The ultimate intention of this pilot study was to make it possible, in the future, to design and justify a study aimed at universalising cardiovascular screening and achieving a long-term decrease in sudden cardiac death events in children.

Causes of sudden cardiac arrest and death and the diagnostic yield of sport preparticipation screening in children

OBJECTIVE

Evidence on the increased risk of sports-related sudden cardiac arrest and death (SCA/D) and the potential benefit of cardiovascular preparticipation screening (PPS) in children is limited. We assessed the burden and circumstances of SCA/D and the diagnostic yield of cardiovascular PPS in children aged 8-15 years.

METHODS

Data on the incidence and causes of SCA/D from 2011 to 2020 were obtained from the Veneto region (Italy) sudden death registry, hospital records and local press. During the same period, we assessed the results of annual PPS in 25 251 young competitive athletes aged 8-15 years who underwent 58 185 evaluations (mean 2.3/athlete) in Padua, Italy.

RESULTS

Over 10 years, 26 SCA/D occurred in children aged 8-15 years in the Veneto region: 6 in athletes (incidence 0.7/100 000/year, all ≥12 years) versus 20 in non-athletes (0.7/100 000/year, 17/20 ≥12 years). In total, 4/6 athletes versus 1/20 non-athletes survived. The cause of SCA/D remained unexplained in four athletes and in nine non-athletes. No athlete suffered SCA/D from structural diseases potentially identifiable by PPS. The incidence of SCA/D in athletes and non-athletes was 0.2/100 000/year in the 8-11 years group versus 1.3/100 000/year in the 12-15 years group. PPS identified 26 new diagnoses of cardiovascular diseases (CVDs) at risk of SCA/D, more often in children ≥12 years old (0.06%/evaluation) than <12 years old (0.02%/evaluation, p=0.02). Among athletes with a negative PPS, two suffered unexplained SCA/D during follow-up, one during exercise.

CONCLUSIONS

In children aged 8-15 years, the incidence of SCA/D and the yield of PPS for identifying at-risk CVD were both substantially higher in those ≥12 years, suggesting that systematic PPS may be more useful beyond this age.

Team Approach: Diagnosis, Management, and Prevention of Sudden Cardiac Arrest in the Athlete

» Sudden cardiac events during sports competition are rare but tragic occurrences that require a timely, comprehensive response by well-prepared athletic trainers and medical providers. This sequence should prioritize prompt emergency medical system activation, immediate initiation of cardiopulmonary resuscitation (CPR), automated early defibrillation (AED), and comprehensive advanced life support efforts.» Exercise-induced cardiac remodeling, referred to as the "athlete's heart," refers to a host of adaptive changes that increase cardiac chamber size and wall thickness to allow for greater pressures and volumes during exercise. This remodeling phenotype may overlap with other inherited cardiomyopathies and cardiac abnormalities, which can complicate clinical care. The long-term implications of this electrical and structural remodeling on cardiac function are unknown.» Although the best screening strategies to optimize primary prevention of sudden cardiac arrest is an evolving topic, the effectiveness of CPR and early defibrillation use in treating out-of-hospital sudden cardiac arrest has been well-established, despite their reported underuse.

[Screening for heart disease in kids and adolescents (Prevencar Program)]

OBJECTIVE

The objective was to develop a screening for heart disease detection in primary care, to identify pathological electrocardiographic changes and underlying heart disease in adolescents.

DESIGN

The study was carried out for one year using multistage sampling. SITE: Primary care centers in a health area that had digital ECG equipment (12 centers) were selected.

PARTICIPANTS

Initially, 718 (16.6%) 14-year-old adolescents were recruited and those with a previous diagnosis of heart disease were excluded.

INTERVENTIONS

Screening consisted of including a health questionnaire in the mandatory 14-year-old check-up.

MAIN MEASUREMENTS

Screening included a questionnaire, cardiac auscultation, ECG and echocardiography. Abnormality criteria were established to refer for a second evaluation by a cardiologist.

RESULTS

Finally, the sample was made up of 698 adolescents, with a mean age of 13.7±0.5 years, and 354 (50.7%) were boys. A total of 149 (21.3%) were selected for a second review by cardiology: 88 (12.6%) due to a positive questionnaire, 11 (2.2%) due to abnormal cardiac auscultation, and 66 (9.5%) due to ECG findings. Adolescents with evidence of heart disease were 24 (3.4%). Of these, 14 (2.0%) had suggestive alterations and follow-up was recommended, 6 (0.9%) had a definitive diagnosis of heart disease, and 4 (0.6%) had other pathological findings related to the cardiovascular system.

CONCLUSIONS

The screening allowed us to identify 1% of adolescents with heart disease and another 2% will remain in follow-up. The ECG detected more pathological cases than the questionnaire.

Cardiovascular Screening before Sports Participation: Results of 11487 Children

AIM

In this study, it is aimed to analyze the data of children who were referred to our clinic for pre-participation sports screening.

METHODS

Data, between September 2017 and December 2021, had been analyzed. All these subjects had been questioned for their personal and family medical stories and examined for cardiovascular system findings. Electrocardiography (ECG) and echocardiography were applied to all of them.

RESULTS

11487 children were consulted to the cardiology clinic for pre-sports participation screening. The mean age was 12.7±4,57 (7-18 years). 34/11487(0,29%) subjects weren't allowed to participate in sports activities at first. In 23 of 34 subjects, cardiac arrhythmias were established. 15 had Wolff-Parkinson-White (WPW) syndrome, 3 subjects had ventricular extrasystole, and also ventricular tachycardia in one of them. Four subjects had long QT syndrome and one had ST elevation with the pre-diagnosis of coronary artery disease. ECG screening alone aided in identifying asymptomatic (0.05%) that could have been potentially at risk for sudden cardiac death.

CONCLUSION

Positive ECG and echocardiography findings involve a very little ratio.But ECG involves an important tool for screening lethal cardiac arrhythmias in asymptomatic patients.If ECG or echocardiography couldn't be taken, further evaluation should be necessary with symptoms and/or family history.

Quality of athlete screening for high-risk cardiovascular conditions-A systematic review

BACKGROUND

Sudden cardiac death (SCD) is the leading medical cause of death in athletes. To prevent SCD, screening for high-risk cardiovascular conditions (HRCC) is recommended. Screening strategies are based on a limited number of studies and expert consensus. However, evidence and efficacy of athlete HRCC screening is unclear.

OBJECTIVE

To determine methodological quality and quality of evidence of athlete screening, and screening efficacy to detect HRCC in a systematic review.

METHODS

We performed a systematic search of Medline, Embase, Scopus and Cochrane Library up to June 2021. We included articles containing original data of athlete cardiovascular screening, providing details of screening strategies, test results and HRCC detection. We assessed methodological quality of the included articles by QUADAS-2, quality of evidence of athlete HRCC screening by GRADE, and athlete HRCC screening efficacy by SWiM.

RESULTS

Of 2720 citations, we included 33 articles (1991-2018), comprising 82 417 athletes (26.7% elite, 73.4% competitive, 21.7% women, 75.2% aged ≤35). Methodological quality was 'very low' (33 articles), caused by absence of data blinding and inappropriate statistical analysis. Quality of evidence was 'very low' (33 articles), due to observational designs and population heterogeneity. Screening efficacy could not be reliably established. The prevalence of HRCC was 0.43% with false positive rate (FPR) 13.0%.

CONCLUSIONS

Methodological quality and quality of evidence on athlete screening are suboptimal. Efficacy could not be reliably established. The prevalence of screen detected HRCC was very low and FPR high. Given the limitations of the evidence, individual recommendations need to be prudent.

The cardiac preparticipation sports evaluation

PURPOSE OF REVIEW

Sudden cardiac death (SCD) is the leading cause of death in young athletes during sports participation. Preparticipation cardiovascular screening aims to identify those at an increased risk of SCD. This review aims to provide a background of SCD in young athletes, to discuss the various screening recommendations of major medical societies, and to review recent evidence and current practice.

RECENT FINDINGS

Numerous studies have evaluated various preparticipation screening practices, particularly regarding the inclusion of ECG as part of an initial evaluation to identify conditions with an increased risk of SCD. Some analyses have shown ECG inclusion to provide increased screening sensitivity and specificity, though others have shown no benefit when compared with evaluation with history and physical examination alone. Furthermore, in countries for which more extensive screening protocols have been employed, postimplementation statistics have not shown a significant decrease in SCD.

SUMMARY

SCD in young athletes primarily results from underlying cardiac disease. Various preparticipation screening recommendations exist globally, with the common goal of decreasing the rates of SCD by identifying youth at risk during sports participation. Current guidelines in the United States support universal preparticipation evaluation using history and physical examination, with cardiology referral if abnormalities are identified.

Sudden cardiac arrest in athletes and strategies to optimize preparedness

Sudden cardiac arrest (SCA) is the leading cause of death in young athletes. Despite efforts to improve preparedness for cardiac emergencies, the incidence of out-of-hospital cardiac arrests in athletes remains high, and bystander awareness and readiness for SCA support are inadequate. Initiatives such as designing an emergency action plan (EAP) and mandating training in cardiopulmonary resuscitation (CPR) and automated external defibrillator use (AED) for team members and personnel can contribute to improved survival rates in SCA cases. This review provides an overview of SCA in athletes, focusing on identifying populations at the highest risk and evaluating the effectiveness of different screening practices in detecting conditions that may lead to SCA. We summarize current practices and recommendations for improving the response to SCA events, and we highlight the need for ongoing efforts to optimize preparedness through the implementation of EAPs and the training of individuals in CPR and AED use. Additionally, we propose a call to action to increase awareness and training in EAP development, CPR, and AED use for team members and personnel. To improve outcomes of SCA cases in athletes, it is crucial to enhance bystander awareness and preparedness for cardiac emergencies. Implementing EAPs and providing training in CPR and AED use for team members and personnel are essential steps toward improving survival rates in SCA cases.

Chest Pain, Palpitations, and Syncope: Preventing Sudden Cardiac Death in Children

Sudden cardiac death is defined as an abrupt, unexpected death of cardiovascular cause with loss of consciousness within 1 hour of onset of symptoms. In an effort to prevent these events, clinicians need to recognize symptoms to identify at risk patients. There is often an overlap in symptoms of chest pain, palpitations, and syncope. The workup depends on the characteristics of these symptoms. The history and physical examination often provide adequate information, but additional testing and referral to pediatric cardiology are sometimes indicated.

Value of screening for the risk of sudden cardiac death in young competitive athletes

AIMS

This study aimed to report the long-term findings of the Italian programme of cardiovascular preparticipation screening (PPS) in young, competitive athletes.

METHODS AND RESULTS

The study assessed the diagnostic yield for diseases at risk of sudden cardiac death (SCD), the costs of serial evaluations, and the long-term outcomes of PPS in a large population of Italian children (age range, 7-18 years). The PPS was repeated annually and included medical history, physical examination, resting electrocardiogram, and stress testing; additional tests were reserved for athletes with abnormal findings. Over an 11-year study period, 22 324 consecutive children [62% males; mean age, 12 (interquartile range, 10-14) years at first screening] underwent a total of 65 397 annual evaluations (median 2.9/child). Cardiovascular diseases at risk of SCD were identified in 69 children (0.3%) and included congenital heart diseases (n = 17), channelopathies (n = 14), cardiomyopathies (n = 15), non-ischaemic left ventricular scar with ventricular arrhythmias (n = 18), and others (n = 5). At-risk cardiovascular diseases were identified over the entire age range and more frequently in children ≥12 years old (n = 63, 91%) and on repeat evaluation (n = 44, 64%). The estimated cost per diagnosis was 73 312€. During a follow-up of 7.5 ± 3.7 years, one child with normal PPS findings experienced an episode of resuscitated cardiac arrest during sports activity (event rate of 0.6/100.000 athletes/year).

CONCLUSION

The PPS programme led to the identification of cardiovascular diseases at risk of SCD over the whole study age range of children and more often on repeat evaluations. Among screened children, the incidence of sport-related cardiac arrest during long-term follow-up was low.

Increasing Utilization of the Preparticipation Physical Evaluation

OBJECTIVE

The American Heart Association and American Academy of Pediatrics endorse the preparticipation physical evaluation (PPE) to screen student athletes for the risk of sudden cardiac arrest. We sought to identify barriers precluding its use and improve utilization.

METHODS

We analyzed documentation of PPE elements during well-care visits of patients aged 12 to 18 years from 5 primary care practices. Employing quality improvement (QI) methodology, we focused on improving PPE utilization in 1 practice by assessing the number of PPE elements addressed per chart. We expanded our QI project to 4 additional practices by using the same interventions but assessing the percentage of charts that had a complete PPE documented.

RESULTS

A baseline analysis of 5 targeted practices revealed an average of 3.5 of 14 PPE elements documented. Using plan-do-study-act cycles, PPE elements addressed increased from 2.5 to 14 over an 18-month period in the initial practice. By spreading successful interventions to 4 other practices, complete PPE utilization increased from a median baseline of 10.0% to a median of 70.0% over a 12-month period. Postintervention, 12 of 16 patients (75%) required additional follow-up with pediatric cardiology beyond the initial consultation, as compared with 2 of 14 patients (14%) preintervention.

CONCLUSION

The PPE is an underutilized but effective tool in screening student athletes for sudden cardiac arrest. QI methodology was helpful in increasing the use of PPE in the primary care setting.

World netball cardiac screening guidelines

Sudden cardiac adverse events remain an area of concern in sport. The precise risk for netball athletes is unknown but the annual incidence of sudden cardiac death in sports is reported at 0.5-2 cases in 100 000 young competitive athletes between the ages of 12-35 years. Cardiac screening in the sport and exercise medicine context aims at identifying pathologies associated with catastrophic events when combined with physical activity. There is an ongoing debate relating to the standardisation of the pre-participatory medical assessment (PPMA). World Netball (WN) commissioned a cardiac screening policy (13 March 2022). The minimum PPMA recommended by World Netball is a history, physical examination, and a resting 12-lead electrocardiogram (ECG). ECGs should be interpreted in accordance with athlete-specific ECG interpretation criteria. Expansion of sports cardiology experience and infrastructure, in combination with universal emergency response planning for sudden cardiac arrest, is intended to safeguard athlete health and player welfare in WN.

Sudden Cardiac Death in Young Individuals: A Current Review of Evaluation, Screening and Prevention

Sudden cardiac death (SCD) can affect all age groups, including young persons. While less common in the age < 35 population, the occurrence of SCD in the young raises concern, with multiple possible etiologies and often unanswered questions. While coronary artery disease is the leading cause in those > 35 years of age, the younger population faces a different subset of pathologies associated with SCD, including arrhythmias and cardiomyopathies. The tragic nature of SCD in the young entails that we explore and implement available screening methods for this population, and perform the necessary investigations such as electrocardiography (ECG) and echocardiography. In this review, we not only explore the vast etiology associated with SCD in those age < 35, but emphasize evaluation methods, who is at risk, and delve into screening of SCD in potential victims and their family members, in an attempt to prevent this traumatic event. Future research must work towards establishing preventative measures in order to reduce SCD, particularly unexplained SCD in the young.

Preparticipation State Cardiac Screening Forms for Athletes

BACKGROUND AND OBJECTIVES

Annual preparticipation physical evaluation (PPE) is used in the United States to screen adolescents for potential causes of sudden cardiac death. The American Heart Association recommends 14 screening elements of history and physical examination. This study sought to define the utilization of these screening elements by each of the 50 states before high school athletics.

METHODS

PPE forms were obtained from the public website of the high school athletics governing body in every state. Form content was analyzed to identify which of the 14 screening elements were explicitly fulfilled. Additional PPE forms provided by private/parochial schools, other professional societies, or independent groups were excluded from this study.

RESULTS

A total of 48 states (96%) had PPE forms posted online. The remaining 2 states (4%) deferred the specific method of PPE documentation to individual school districts and provided no standardized form. Of the 48 states providing PPE forms, 13 (27%) included all 14 American Heart Association screening elements. The median criteria included by each state was 11 (range 3-14). The 3 criteria most commonly absent were (1) the examination of femoral pulses to exclude coarctation (58%), (2) a family history of specific inherited cardiac disease (31%), and (3) personal history of hypertension (27%).

CONCLUSIONS

Annual preparticipation forms are important screening tools. Only a minority of states include all 14 cardiac screening elements recommended by the American Heart Association.

Sudden death in young athletes: Is it preventable?

Sudden death in young athletes is a rare but always dramatic condition. Unlike all other rare diseases, the estimate of its real incidence is made complex not only because of the uncertain number of correctly identified cases (numerator) but also because of the uncertain estimation of the real number of the reference population, the athletes (denominator). New elements of complexity are also emerging with regard to prevention. The current two pillars of prevention are pre-participation screening (proactive strategy) and promoting use / access to the automated external defibrillator (reactive strategy). The standardization of procedures implemented over the past two decades for pre-participation screening can now allow us to assess the impact of this approach. The result is complex to evaluate. While screening may allow the identification of conditions potentially associated with SDA, and therefore the adoption of specific treatments, in about 0.4% of screened subjects, a single study investigated the yield in terms of mortality showing a positive predictive value of 4.7% with 25% sensitivity. Conversely, the reactive strategy appears considerably effective, due to the widespread use of the automated external defibrillators in sports facilities, calling for a homogeneous implementation worldwide. On a broader perspective, the vast attention devoted to SDA prevention in the world of sports represents a major driver for transfer of a reactive prevention strategy to the general population.

Risk Factors for Sudden Death in Athletes, Is There a Role for Screening?

Purpose of Review

Sudden cardiac death (SCD) in a young athlete is an infrequent yet devastating event often associated with substantial media attention. Screening athletes for conditions associated with SCD is a controversial topic with debate surrounding virtually each component including the ideal subject, method, and performer/interpreter of such screens. In fact, major medical societies such as the American College of Cardiology/American Heart Association and the European Society of Cardiology have discrepant recommendations on the matter, and major sporting associations have enacted a wide range of screening policies, highlighting the confusion on this subject. This review seeks to summarize the literature in this area to address the complex and disputed subject of screening young athletes for SCD.

Recent Findings

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can cause myocarditis, which is one acquired cardiac disease associated with SCD. The coronavirus 2019 (COVID-19) pandemic has therefore resulted in an increased incidence of an otherwise less common condition, providing an expanded dataset for further study of this condition. Recent findings indicate that cardiac complications of athletes with myocardial involvement of SARS-CoV-2 infection are rare. Other contemporary work in SCD screening has been focused on the implementation of various screening protocols and measuring their effectiveness.

Summary

No universal consensus exists for athlete screening for conditions associated with SCD with varying guidelines and protocols across cardiology and sport-specific organizations. No screening program will prevent all SCD; however, small programs managed by physicians familiar with the examination of an athlete that carefully personalize screening to the individual may maximize detection of dangerous cardiac conditions while minimizing false positives.

Patterns and demographic correlates of domain-specific physical activities and their associations with dyslipidaemia in China: a multiethnic cohort study

OBJECTIVE

To evaluate the patterns and demographic correlates of domain-specific physical activities (PAs) and their associations with dyslipidaemia among ethnic minorities in China.

DESIGN

Cross-sectional.

PARTICIPANTS

In total, 17 081 individuals were included.

PRIMARY AND SECONDARY OUTCOME MEASURES

Domain-specific PAs were assessed using a questionnaire related to occupational, transportation, housework and leisure-time PAs. Dyslipidaemia was measured using an automatic biochemical instrument. Demographic variables were self-reported.

RESULTS

Housework accounted for most PAs in the study. Elderly people were more likely to participate in housework and leisure-time PA, whereas the mean level of PA in people with low education level and household income was high. With G3-G4 levels of occupational PA, Dong men (G4: OR=0.530, 95% CI 0.349 to 0.806), Miao women (G3: OR=0.698, 95% CI 0.524 to 0.931; G4: OR=0.611, 95% CI 0.439 to 0.850) and Bouyei women (G3: OR=0.745, 95% CI 0.566 to 0.981; G4: OR=0.615, 95% CI 0.440 to 0.860) tended to have a low risk of dyslipidaemia. With G2 levels of transportation, PA could reduce the risk of dyslipidaemia in Bouyei women (G2: OR=0.747, 95% CI 0.580 to 0.962). G2-G3 levels of leisure-time PA could reduce the risk of dyslipidaemia in Miao men (G2: OR=0.645, 95% CI 0.446 to 0.933; G3: OR=0.700, 95% CI 0.513 to 0.954). However, a high risk of dyslipidaemia was observed with G4 levels of leisure-time PA among Bouyei women (G4: OR=.353, 95% CI 1.001 to 1.905) and with transportation PA among Dong men (G4: OR=1.591, 95% CI 1.130 to 2.240).

CONCLUSION

The main PA of the ethnic minorities in Guizhou Province involved housework. Domain-specific PAs varied with demographic factors, and active domain-specific PAs were associated with a reduced risk of dyslipidaemia.

Findings From Cardiovascular Evaluation of National Collegiate Athletic Association Division I Collegiate Student-Athletes After Asymptomatic or Mildly Symptomatic SARS-CoV-2 Infection

OBJECTIVE

The risk of myocardial damage after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been controversial. The purpose of this study is to report the incidence of abnormal cardiovascular findings in National Collegiate Athletic Association (NCAA) Division I student-athletes with a history of SARS-CoV-2 infection.

DESIGN

This is a case series of student-athletes with SARS-CoV-2 infection and their subsequent cardiac work-up, including troponin level, electrocardiogram, and echocardiogram. Additional testing was ordered as clinically indicated.

SETTING

This study was conducted at a single NCAA Division I institution.

PARTICIPANTS

Student-athletes were included if they tested positive for SARS-CoV-2 by PCR or antibody testing [immunoglobulin G (IgG)] from April 15, 2020 to October 31, 2020.

INTERVENTION

Cardiac testing was conducted as part of postinfection screening.

MAIN OUTCOME MEASURES

This study was designed to quantify abnormal cardiovascular screening results and cardiac diagnoses after SARS-CoV-2 infection in Division I collegiate athletes.

RESULTS

Fifty-five student-athletes tested positive for SARS-CoV-2. Of these, 14 (26%) had a positive IgG and 41 (74%) had a positive PCR test. Eight abnormal cardiovascular screening evaluations necessitated further testing including cardiac magnetic resonance imaging (cMRI). Two athletes received new cardiac diagnoses, one probable early cardiomyopathy and one pericarditis, whereas the remaining 6 had normal cMRIs.

CONCLUSIONS

These data support recent publications which recommend the de-escalation of cardiovascular testing such as cardiac MRI or echocardiogram for athletes who have recovered from asymptomatic or mildly symptomatic SARS-CoV-2 infection. Continued follow-up of these athletes for sequelae of SARS-CoV-2 is critical.

Results of a nationally implemented cardiac screening programme in elite cricket players in England and Wales

OBJECTIVES

We assessed the diagnostic yield and costs of an electrocardiogram-based national screening programme in elite cricket players and the incremental value of transthoracic echocardiography and periodic evaluation.

DESIGN

Cross-sectional study.

METHODS

Between 2008 and 2019, 1208 cricketers underwent screening with a health questionnaire, 12-lead electrocardiogram and cardiology consultation. Athletes with concerning findings underwent on-site transthoracic echocardiography and further investigations as necessary. In addition, despite a normal health questionnaire and electrocardiogram, 342 (28.3%) athletes had a transthoracic echocardiogram and 493 (40.8%) underwent repeat evaluations.

RESULTS

After initial evaluation, 47 (3.9%) athletes underwent on-site transthoracic echocardiography of whom 35 (2.8%) were referred for further evaluation. Four athletes (0.3%) were diagnosed with major cardiac conditions; hypertrophic cardiomyopathy (n = 1), arrhythmogenic cardiomyopathy (n = 1) and Wolff-Parkinson-White pattern (n = 2). Two athletes were identified with minor valvular abnormalities. Repeat evaluation of 493 athletes identified hypertrophic cardiomyopathy in a 22-year-old athlete, two years after his initial normal screening. During a follow-up of 5.8 ± 2.9 years no additional diagnoses or adverse cardiac events were reported. The cost of the electrocardiogram-based programme was £127,844, translating to £106 per athlete and £25,569 per major cardiac condition identified.Routine transthoracic echocardiography in 342 athletes identified two athletes with major cardiac conditions (bicuspid aortic valve with severe aortopathy and aortic regurgitation and an atrial septal defect associated with right ventricular volume overload) and 10 athletes with minor abnormalities.

CONCLUSIONS

An electrocardiogram-based national screening programme identified a major cardiac condition in 0.3% of athletes. Routine transthoracic echocardiography and periodic evaluation increased the diagnostic yield to 0.6%, at an incremental cost.

Athlete Preparticipation Physical Evaluation

Preparticipation evaluations (PPE) are both a traditional and legal requirement by many governing bodies for sport. The ideal goal of the PPE is safe participation in sport for athletes. This article provides an overview of common PPE elements and current best practice recommendations. Descriptions of every possible examination are published elsewhere and are beyond the intent of this article. Additional considerations for transgender, masters athletes, and Special Olympians are also outside the scope of this review, but are well covered in The Preparticipation Physical Evaluation, fifth edition monograph.

Diagnostic yield and cost analysis of electrocardiographic screening in Swiss paediatric athletes

OBJECTIVES

Athletes performing sports on high level are at increased risk for sudden cardiac death. This includes paediatric athletes, even though data on screening strategies in this age group remain scarce. This study aimed to assess electrocardiogram interpretation criteria in paediatric athletes and to evaluate the cost of screening.

METHODS

National, multicentre, retrospective, observational study on 891 athletes of paediatric age (<18 years) evaluated by history, physical examination and 12-lead electrocardiogram. The primary outcome measure was abnormal electrocardiogram findings according to the International Recommendations for Electrographic Interpretation in Athletes. The secondary outcome measure was cost of screening.

RESULTS

19 athletes (2.1%) presented abnormal electrocardiogram findings requiring further investigations, mainly abnormal T-wave inversion. These 19 athletes were predominantly males, performing endurance sports with a mean volume of 10 weekly hours for a mean duration of 6 years of training. Further investigations did not identify any relevant pathology. All athletes were cleared for competition with regular follow-up. Total costs of the screening were 108,860 USD (122 USD per athlete).

CONCLUSIONS

Our study using the International Recommendations for Electrographic Interpretation in Athletes identified a low count of abnormal findings in paediatric athletes, yet raising substantially the cost of screening. Hence, the utility of electrocardiogram-inclusive screening of paediatric athletes remains to be elucidated by longitudinal data.

Screening for hypertrophic cardiomyopathy

ABSTRACT

Hypertrophic cardiomyopathy (HCM) is the most common inherited cardiomyopathy and causes changes in the cardiac muscle affecting ventricular, valvular, and cellular functions. Because HCM is an inherited disorder, all age groups are affected; however, it commonly presents in adolescents, especially athletes. Many patients are asymptomatic and undiagnosed, putting them at risk for sudden cardiac death. This article describes screening and management of patients with HCM.

Potential role of an athlete-focused echocardiogram in sports eligibility

Sudden cardiac death (SCD) of an athlete is a rare but tragic event and sport activity might play a trigger role in athletes with underlying structural or electrical heart diseases. Preparticipation screenings (PPs) have been conceived for the potential to prevent SCD in young athletes by early identification of cardiac diseases. The European Society of Cardiology protocol for PPs includes history collection, physical examination and baseline electrocardiogram, while further examinations are reserved to individuals with abnormalities at first-line evaluation. Nevertheless, transthoracic echocardiography has been hypothesized to have a primary role in the PPs. This review aims to describe how to approach an athlete-focused echocardiogram, highlighting what is crucial to focus on for the different diseases (cardiomyopathies, valvulopathies, congenital heart disease, myocarditis and pericarditis) and when is needed to pay attention to overlap diagnostic zone ("grey zone") with the athlete's heart. Once properly tested, focused echocardiography by sports medicine physicians may become standard practice in larger screening practices, potentially available during first-line evaluation.

Comparison of the Limb-lead Electrocardiogram to the 12-Lead Electrocardiogram for Identifying Conditions Associated with Sudden Cardiac Death in Youth Athletes

The optimal screening strategy to prevent sudden cardiac death (SCD) in athletes remains unknown. Pre-participation screening with electrocardiogram (ECG) remains controversial. The utility and accuracy of limb-lead (LL) ECG alone in identifying cardiac abnormalities associated with SCD has not been studied. This study was a comparative secondary data analysis, comparing the interpretation accuracy of 4 physicians evaluating publicly available ECGs of the most common cardiac conditions associated with SCD in athletes. Each physician interpreted a total of 100 ECGs: 50 normal ECGs (25 LL and 25 standard 12L) and 50 abnormal ECGs (25 LL and 25 standard 12L). The agreement between LL ECGs and 12L ECGs was assessed by Cohen's kappa coefficient and the accuracy of identifying an abnormal ECG was compared across LL and 12L ECGs using a chi-squared test. Inter-rater reliability was assessed by estimating the Fleiss's kappa coefficient. The sensitivity of LL ECG and 12L ECG was identical at 86%. The specificity of LL ECG was 75% (95% CI = 65% to 83%) and 12L ECG was 82% (95% CI = 73% to 89%). Substantial agreement was seen between LL ECG and 12L ECG interpretation across all readers (k = 0.63; 95% CI = 0.49 to 0.77). Interpretation accuracy was 81% (95% CI = 74% to 86%) and 84% (95% CI 78% to 89%) using LL ECG and 12L ECG, respectively (p = 0.43). In conclusion, the accuracy, sensitivity, and specificity were high and comparable for both LL ECG and 12L ECG in identifying cardiovascular conditions associated with SCD. Agreement between LL ECG and 12L ECG was substantial.

Young athletes: Preventing sudden death by adopting a modern screening approach? A critical review and the opening of a debate

Preventing sudden cardiac death (SCD) in athletes is a primary duty of sports cardiologists. Current recommendations for detecting high-risk cardiovascular conditions (hr-CVCs) are history and physical examination (H&P)-based. We discuss the effectiveness of H&P-based screening versus more-modern and accurate methods. In this position paper, we review current authoritative statements and suggest a novel alternative: screening MRI (s-MRI), supported by evidence from a preliminary population-based study (completed in 2018), and a prospective, controlled study in military recruits (in development). We present: 1. Literature-Based Comparisons (for diagnosing hr-CVCs): Two recent studies using traditional methods to identify hr-CVCs in >3,000 young athletes are compared with our s-MRI-based study of 5,169 adolescents. 2. Critical Review of Previous Results: The reported incidence of SCD in athletes is presently based on retrospective, observational, and incomplete studies. H&P's screening value seems minimal for structural heart disease, versus echocardiography (which improves diagnosis for high-risk cardiomyopathies) and s-MRI (which also identifies high-risk coronary artery anomalies). Electrocardiography is valuable in screening for potentially high-risk electrophysiological anomalies. 3. Proposed Project : We propose a prospective, controlled study (2 comparable large cohorts: one historical, one prospective) to compare: (1) diagnostic accuracy and resulting mortality-prevention performance of traditional screening methods versus questionnaire/electrocardiography/s-MRI, during 2-month periods of intense, structured exercise (in military recruits, in advanced state of preparation); (2) global costs and cost/efficiency between these two methods. This study should contribute significantly toward a comprehensive understanding of the incidence and causes of exercise-related mortality (including establishing a definition of hr-CVCs) while aiming to reduce mortality.

Screening electrocardiogram in young athletes and military members: a systematic review and meta-analysis

OBJECTIVE

To determine the effect of electrocardiogram (ECG) screening on prevention of sudden cardiac arrest and death (SCA/D) in young athletes and military members.

DATA SOURCES

MEDLINE, Embase, Cochrane CENTRAL, Web of Science, BIOSIS, Scopus, SPORT discus, PEDro, and clinicaltrials.gov were searched from inception to dates between 2/21/19 and 7/29/19.

STUDY SELECTION

Randomized and non-randomized controlled trials, where pre-participation examination including ECG was the primary intervention used to screen athletes or military 40 years of age or younger. Accepted controls were no screening, usual care, or pre-participation examination without ECG. 3 published studies , and one conference abstract were identified for inclusion.

DATA EXTRACTION

In all four studies, risk of bias was assessed with the Cochrane risk of bias tool, and found to be generally high. Two studies had data extracted for random effects meta-analysis, and the remaining study and conference abstract were included in narrative review. Overall quality of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) Data Synthesis: Four non-randomized studies (11,689,172 participants) were included, all at high risk of bias. Pooled data from two studies (n= 3,869,274; very low quality evidence) observed an inconclusive 42% relative decrease in risk of sudden cardiac death (RR 0.58; 95% CI 0.23, 1.45), equating to an absolute risk reduction of .0016% The findings were consistent with a potential 67% relative decrease to a 45% relative increased risk in participants screened with ECG. Heterogeneity was found to be high as measured with I2 statistic (71%). Data from the remaining study and abstract were similarly inconclusive.

CONCLUSION

Existing evidence for the effect of ECG screening is inconclusive and of very low quality. Our meta-analysis observed that screening ECG may result in considerable benefit or harm to participants. Higher quality studies are needed to reduce this uncertainty. PROSPERO Registration: CRD42019125560.

Implementing a Standardized Cardiac Protocol for the Adolescent Preparticipation Sports Examination

INTRODUCTION

To evaluate adolescent athletes for cardiovascular (CV) abnormalities before engaging in competitive sports, the American Heart Association guidelines recommend preparticipation screening. The initiative aimed to implement a standardized protocol to increase the identification of CV abnormalities during athletic physical examinations.

METHOD

A rapid-cycle model with four Plan-Do-Study-Act cycles was implemented in two urgent care clinics. Providers used a CV-specific screening checklist; parents were engaged in a discussion about the importance of this screening, and team engagement activities were used. Outcomes were measured with chart audits and surveys.

RESULTS

Because of the intervention, 62% of athletes were screened, with 29% identified as having a CV risk. The satisfaction of the patients and the team increased by 3% and 62.5%, respectively.

DISCUSSION

Despite competing foci in the clinics, athletes were properly screened using a standardized checklist, which is easily sustainable and can be duplicated in other settings.

Electrocardiographic pattern of apparently healthy African adolescent athletes in Nigeria

Background

Strategies to prevent sudden cardiac death (SCD) among young athletes have become topical worldwide and unrecognized cardiac pathology has been identified as a leading cause. Black ethnicity has been reported as an independent predictor of abnormal electrocardiography (ECG) findings among athletes and the frequency and significance of training-related ECG findings versus findings suggestive of an underlying pathology in the young African athletes is crucial.

Methods

This cross sectional study aimed to determine the prevalence and distribution of ECG patterns in young athletes and controls. A total of 360 participants (180 athletes and 180 controls) were recruited from six secondary schools in Lagos, Nigeria between November 2014 and July 2015. Evaluation included interviewer-administered questionnaires for relevant history, physical examination and resting 12 - lead ECG for each participant.

Results

Abnormal ECG patterns were found in 48.3% of athletes and 35.6% of controls. Training-related ECG findings occurred in 33.3% of athletes and 18.3% of controls. Athletes and controls had 7.7% prevalence of training un-related ECG patterns respectively. Left ventricular hypertrophy was the most common ECG finding among the athletes and male athletes had a higher prevalence of ECG abnormalities compared to females.

Conclusion

Adolescent athletes in Nigeria have a high prevalence of training-related ECG patterns and athletes and non-athletes alike have similar proportions of ECG findings suggestive of underlying structural heart disease. Cardiovascular evaluation including ECG should be performed for young athletes prior to competition at any level and should also be considered as part of pre-school entry assessment for all children.

Pre-participation Cardiovascular Screening in Young Competitive Athletes

Purpose of Review

The purpose of this review was to highlight the current recommendations, data, and limitations for methods of cardiovascular screening in athletes.

Recent Findings

While the history and physical (H&P) alone remains the cornerstone for preparticipation cardiovascular screening (PPCS) in athletes, the advent of modern electrocardiographic (ECG) screening criteria has drastically increased sensitivity and decreased false positive rates for screening. Advanced imaging techniques remain an important component of secondary testing after an athlete has an abnormal initial screening exam, however, the use of imaging for universal screening has not been rigorously tested to date. Current disqualification guidelines have now begun to emphasize shared decision making between the provider and athlete in situations of clinical equipoise.

Summary

All major medical and sporting societies recommend PPCS using a focused medical history and physical examination for all competitive athletes, but there remains controversy about the role of ECG and advanced imaging in PPCS. Future research should focus on the creation of a randomized trial that is powered for mortality that can truly assess the utility of PPCS in athletes.

Typical and reverse Takotsubo syndromes as initial manifestations of consecutive Addisonian crises in a 38-year-old patient: the heart has its reasons!

We report an interesting case of a 38-year-old woman presenting with reverse Takotsubo syndrome (TTS) secondary to an Addisonian crisis, her second such episode. A few years prior, she had presented with typical TTS in the setting of Addisonian crisis; diagnostic work-up revealing Auto-Immune Polyglandular Syndrome Type II (APS II). We believe this to be the first case report of typical and variant phenotypes of TTS in a patient with APS II. The pathogenic link between these two conditions is explored. In patients presenting with Addisonian crises and refractory shock, the possibility of concurrent TTS should be considered. TTS muddies the diagnostic waters and poses therapeutic challenges as outlined.

Routine pre-employment echocardiography assessment in young adults: cost and benefits

Background

Conventional echocardiography is a safe, available, and accurate tool for cardiac structural and functional evaluation, but it should not cancel clinical assessment and history tacking, and indeed both are complementary. A pre-employment assessment is important for employees and community safety and suitability for a specific work requirement.

Results

Aiming to assess the value of routine pre-employment echocardiography for the detection of cardiac abnormalities, we examined seven hundred ninety-five persons who were routinely referred to us for pre-employment conventional echocardiography. Only 9 persons had structural cardiac abnormalities (1.3%) and distributed as follows: two had bicuspid aortic valve with isolated aortic regurgitation, one of them had mild AR, and the other had moderate AR. Two cases had mitral valve prolapse, one of them had trivial MR, while the other had a flail anterior leaflet with severe MR. One patient had atrial septal defect 1.5 cm with mild pulmonary hypertension and right-sided chambers dilatation. One patient had dextrocardia (situs inversus totalis) without other cardiac problems. One had moderate pulmonary hypertension and modest right-sided chambers dilation. Two patients had left ventricular hypertrophy. Surprisingly, we did not detect rheumatic valvular heart disease. The money cost of echocardiography tests for those 795 persons was 198,750 Egyptian pounds (LE); their transportation cost was about 19.800LE. The total group time cost of the tests was 265 h, total time lost at the waiting room was 1590 h, total transportation time lose was 2385 h, so the total time cost was about 4000 h. Using psychological stress questionnaire, 33 participants (4.2%) had results suggestive of a low sense of psychological pressure due to echocardiography examination, 221 participants (27.8%) had results suggestive of a moderate feeling of stress, while 541 participants (68%) had results suggestive of a high sense of stress.

Conclusion

We recommend against routine echocardiography for cardiac assessment in pre-employment assessment and to do it only for persons with abnormal clinical or ECG findings.

Feasibility and diagnostic performance of including point-of-care ultrasound (POCUS) in preparticipation screening of young competitive athletes

Optimal pre-participative screening in young athletes is still controversial. We sought to evaluate the strategy of including point-of-care ultrasound to electrocardiogram. In total, 1188 young competitive athletes were screened in different sports institutions. This proved to be a useful strategy by improving diagnostic performance primarily with respect to detect structural abnormalities and also by minimising positive false cases of electrocardiogram alone.

Aetiology and incidence of sudden cardiac arrest and death in young competitive athletes in the USA: a 4-year prospective study

Objective

To investigate the aetiology and incidence of sudden cardiac arrest and death (SCA/D) in US competitive athletes.

Methods

Prospective surveillance was conducted from 1 July 2014 to 30 June 2018 through the National Center for Catastrophic Sports Injury Research in collaboration with national sports organisations. Autopsy reports, death certificates, and medical records were reviewed by an expert panel to determine aetiology. Athlete participation statistics from the National Federation of State High School Associations and the National Collegiate Athletic Association (NCAA) were used to calculate incidence rates per athlete-years (AY). Comparisons of incidence rates were calculated using incidence rate ratios (IRR) with 95% CIs.

Results

331 cases of confirmed SCA/D (158 survivors; 173 fatalities) were identified; 15.4% in middle school, 61.6% in high school and 16.6% in college and professional athletes. Average age was 16.7 (11–29) years, and the majority were in male (83.7%), basketball (28.7%) or American football (25.4%) athletes. Common causes included hypertrophic cardiomyopathy (20.6%), idiopathic left ventricular hypertrophy (13.4%), coronary artery anomalies (12.0%) and autopsy-negative sudden unexplained death (9.6%). Coronary anomalies were more common in middle school athletes (28%), while cardiomyopathies (hypertrophic, arrhythmogenic, dilated, non-compaction or restricted) accounted for 47% of cases in college and professional athletes. Incidence was higher in male versus female athletes at the high school (1:43 932 AY (95% CI 1:38 101 to 1:50 907) vs 1:203 786 AY (95% CI 1:145 251 to 1:293 794); IRR 4.6 (95% CI 3.1 to 7.2)) and NCAA (1:34 906 AY (95% CI 1:25 385 to 1:49 173) vs 1:123 278 AY (95% CI 1:66 078 to 1:249 853); IRR 3.5 (95% CI 1.5 to 9.5)) levels. African American male NCAA Division I basketball players had the highest annual incidence rate of SCA/D (1:2087 AY (95% CI 1:1073 to 1:4 450)).

Conclusions

Cardiomyopathies account for nearly half of SCA/D cases in college and professional athletes, while coronary artery anomalies play a more prominent role than expected in middle school athletes. Over half of SCA cases in athletes result in sudden death, calling for improved prevention strategies.

Cardiac Screening to Mitigate the Risk of Sudden Cardiac Death in Middle Eastern and African Competitive Athletes. A Systematic Review

OBJECTIVE

The study aims to review the literature regarding abnormalities predisposing to Sudden Cardiac Death (SCD) in young Middle Eastern and African competitive athletes between the years 2009-2019 and aims to assess cardiac pre-participation screening methods.

METHODS

A PubMed search was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The search targeted articles that reported the prevalence of cardiac abnormalities found in Middle Eastern and African athletes, and it also focused on comparing cardiac screening methods for assessment of athletes.

RESULTS

our studies fell within the inclusion criteria and were included in the study. Results identified a shortage in the literature regarding prevalence rates of SCD in the Middle East and Africa. Additionally, there seems to be a lack of ethnicity-specific cardiac pre-participation screening programs in the region. Nevertheless, the prevalence of SCD-related abnormalities (HCM, ARVC, etc …) ranged from 0.47 to 4.29%. Included studies conveyed only male athletes with no reports on the female athletic population.

CONCLUSION

The present study highlights a need to develop an efficient cardiac pre-participation screening program specific to Arab and African athletes due to their high false-positive rates in contrast to Caucasian athletes. Significant evidence proves that an adequate cardiac screening program can prevent SCD in young competitive athletes. Therefore, it is imperative that future studies highlight the prevalence of abnormalities directly related to SCD in order to create a valid screening program that can be implemented in the region to mitigate the risk of shocking events.

Youth running consensus statement: minimising risk of injury and illness in youth runners

Despite the worldwide popularity of running as a sport for children, relatively little is known about its impact on injury and illness. Available studies have focused on adolescent athletes, but these findings may not be applicable to preadolescent and pubescent athletes. To date, there are no evidence or consensus-based guidelines identifying risk factors for injury and illness in youth runners, and current recommendations regarding suitable running distances for youth runners at different ages are opinion based. The International Committee Consensus Work Group convened to evaluate the current science, identify knowledge gaps, categorise risk factors for injury/illness and provide recommendations regarding training, nutrition and participation for youth runners.

Current controversies in pre-participation cardiovascular screening for young competitive athletes

INTRODUCTION

Pre-participation cardiovascular screening (PPCS) in athletes is recommended by numerous medical and sporting societies. While there is consensus that young athletes should be screened prior to participation in competitive sports, there are on-going debates regarding the true incidence of sudden cardiac death (SCD), the most frequent causes of SCD, and the optimal methods for PPCS.

AREAS COVERED

This review focuses on the current evidence for the incidence of SCD, causes of SCD, and the pros and cons of a history and physical exam (H&P) and electrocardiogram (ECG) in PPCS of young competitive athletes.

EXPERT OPINION

With significant controversy surrounding PPCS in athletes, a large-randomized trial powered for mortality is needed to assess the utility of PPCS and to define the optimal screening methods to detect cardiovascular diseases that may lead to SCD in competitive athletes. Until a trial of this caliber is created, controversy will remain and heterogeneity in care will exist. Future research should also define the optimal timing and frequency of PPCS given age-related penetrance of certain diseases, create evidence-based history questionnaires, continue to optimize ECG screening criteria, and create more learning modules for ECG interpretation in athletes.
