F-MARC: promoting the prevention and management of sudden cardiac arrest in football

FIFA Initiatives Improved Survival After Loss of Consciousness During Football Games

Loss of consciousness (LOC) during football games is associated with very high mortality rates. In order to address football medical emergencies, in 2013 FIFA implemented the "FIFA 11 steps to prevent sudden cardiac death" program and distributed the FIFA Medical Emergency Bag. The purpose of this work was to identify independent survival factors after LOC on the pitch and to investigate the effectiveness of the FIFA initiatives. An internet search was performed to identify football players suffering LOC on the pitch between 1990 and 2021. A total of 268 cases could be identified and were dichotomized according to the implementation date of the FIFA medical emergency bag. There was 55% mortality after LOC, while cardiogenic LOC was more often (82% vs. 20%) fatal than traumatic LOC. Mortality in developing countries was higher than in developed countries. From the year 2013 survival improved significantly for both traumatic and cardiogenic cases. The location of the LOC significantly influenced survival (OR: 0.20 and p<0.001). LOC on the football field is associated with increased mortality and requires separate monitoring based on a traumatic vs. non-traumatic cause. FIFA initiatives significantly reduced mortality after LOC but significant differences were identified between developed and developing countries.

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.

Immediate Bystander Cardiopulmonary Resuscitation to Sudden Cardiac Arrest During Sports is Associated with Improved Survival-a Video Analysis

Background

Sudden cardiac arrest (SCA) during sports can be the first symptom of yet undetected cardiovascular conditions. Immediate chest compressions and early defibrillation offer SCA victims the best chance of survival, which requires prompt bystander cardiopulmonary resuscitation (CPR).

Aims

To determine the effect of rapid bystander CPR to SCA during sports by searching for and analyzing videos of these SCA/SCD events from the internet.

Methods

We searched images.google.com, video.google.com, and YouTube.com, and included any camera-witnessed non-traumatic SCA during sports. The rapidity of starting bystander chest compressions and defibrillation was classified as < 3, 3–5, or > 5 min.

Results

We identified and included 29 victims of average age 27.6 ± 8.5 years. Twenty-eight were males, 23 performed at an elite level, and 18 participated in soccer. Bystander CPR < 3 min (7/29) or 3–5 min (1/29) and defibrillation < 3 min was associated with 100% survival. Not performing chest compressions and defibrillation was associated with death (14/29), and > 5 min delay of intervention with worse outcome (death 4/29, severe neurologic dysfunction 1/29).

Conclusions

Analysis of internet videos showed that immediate bystander CPR to non-traumatic SCA during sports was associated with improved survival. This suggests that immediate chest compressions and early defibrillation are crucially important in SCA during sport, as they are in other settings. Optimal use of both will most likely result in survival. Most videos showing recent events did not show an improvement in the proportion of athletes who received early resuscitation, suggesting that the problem of cardiac arrest during sports activity is poorly recognized.

Professional footballers have a limited understanding of the precompetition medical assessment and the possible outcomes including disqualification: a cross-sectional survey

Objectives

To determine professional footballers’ level of understanding of the purpose of the precompetition medical assessment (PCMA) and to evaluate their knowledge of potential outcomes following a PCMA, including disqualification.

Methods

Professional footballers from the Australasian A-League and Westfield W-League were asked to complete a 25-question survey. The relationship between dichotomised outcomes and explanatory variables was analysed with multivariate logistic regression; p<0.05 was considered statistically significant.

Results

A total of 212 players participated (response rate=48.8%). Most respondents selected ‘To detect medical conditions that may affect performance’ and ‘To detect current injuries’ (n=137, 64.6%; n=130, 61.3%) as the purpose of a PCMA. Approximately one-third (n=74, 38.1%) were neutral or believed that a normal PCMA prevented cardiac arrest. Receiving more PCMAs (p<0.0003) and receiving an explanation during their PCMA (p=0.0175) led to greater awareness of the assessment’s limitations. Most participants did not know the definitions of syncope (n=181, 93.3%) or Marfan syndrome (n=183, 94.3%). Fifty players (28.1%) did not know that disqualification was a possible outcome of a PCMA, and younger players were less aware of this possible outcome (p=0.0216).

Conclusion

Professional footballers appear to have a limited understanding of the purpose of a PCMA, emphasising the musculoskeletal system and performance. They also appear unfamiliar with the components of the PCMA and medical terms. Finally, many are unaware that disqualification can result from an abnormal PCMA. Player health knowledge must be improved; the informed consent process appears an ideal time to provide this education.

Cardiac Structure and Function in Elite Female and Male Soccer Players

Importance

Population-specific normative data are essential for the evaluation of competitive athletes. At present, there are limited data defining normal electrocardiographic (ECG) and echocardiographic values among elite US soccer players.

Objective

To describe ECG and echocardiographic findings in healthy elite US soccer players.

Design, Setting, and Participants

This cross-sectional study analyzed Fédération Internationale de Football Association-mandated screening sessions performed at US Soccer National Team training locations from January 2015 to December 2019. US women's and men's national team soccer players undergoing mandated cardiovascular screening were included.

Main Outcomes and Measures

Normal training-related and abnormal ECG findings were reported using the International Recommendations for Electrocardiographic Interpretation in Athletes. Echocardiographic measurements of structural and functional parameters relevant to cardiovascular remodeling were assessed relative to American Society of Echocardiography guideline-defined normal ranges.

Results

A total of 238 athletes (122 [51%] female; mean [SD] age, 20 [4] years; age range, 15-40 years) were included. Male athletes demonstrated a higher prevalence of normal training-related ECG findings, while female athletes were more likely to have abnormal ECG patterns (14 [11%] vs 0 in male cohort), largely accounted for by abnormal T-wave inversions. Echocardiography revealed no pathologic findings meeting criteria for sport restriction, but athletes frequently exceeded normal ranges for structural cardiac parameters responsive to exercise-induced remodeling including body surface area-indexed left ventricular (LV) mass (58 of 113 female athletes [51%] and 67 of 114 male athletes [59%]), indexed LV volume (89 of 115 female athletes [77%] and 76 of 111 male athletes [68%]), and LV wall thickness (37 of 122 female athletes [30%] and 47 of 116 male athletes [41%]). Age-stratified analysis revealed age-dependent increases in LV wall thickness, mass, and volumes among female athletes and LV wall thickness and mass among male athletes.

Conclusions and Relevance

These data represent the first set of comprehensive normative values for elite US soccer players and one of the largest sport-specific echocardiographic remodeling studies in female athletes. Abnormal ECG findings were more common in female athletes, while both female and male athletes frequently exceeded clinical normality cut points for remodeling-associated echocardiographic parameters.

OPHTHALMOLOGIC EVALUATION IN PROFESSIONAL MALE SOCCER PLAYERS IN BRAZIL

ABSTRACT Introduction: Soccer is the most popular sport in Brazil and worldwide, but there is insufficient data on the eye health of soccer players, and eye conditions may affect the well-being and performance of these athletes. Objective: To perform an ocular evaluation of a representative sample of professional soccer players from Brazil. Methods: This was a cross-sectional study conducted over four consecutive years (2009-2012) at a single professional soccer club in Brazil. The ophthalmology evaluation was performed by the same ophthalmologist in each sample. Prior to the ophthalmology evaluation, all participants filled out a questionnaire to provide the following demographic data: age, position, use of contact lenses or ophthalmic drugs, symptoms, previous ocular surgery, and date of the last ophthalmology evaluation. Visual acuity, intraocular pressure (IOP) and color vision were tested during the ophthalmologic examination, and ophthalmoscopy and biomicroscopy exams were performed. Results: One hundred and twenty bilateral ophthalmology evaluations were performed in 84 professional soccer players between 2009 and 2012. Pinguecula and pterygium were the most common conditions found in the athletes’ biomicroscopy exams, corresponding to 63% (38/60) and 17% (10/60) of abnormalities, respectively. In the contrast sensitivity evaluation, only one athlete was color blind. No significant associations were found between the position of the athlete and the results of the biomicroscopy and ophthalmoscopy exams. Conclusion: Despite the high prevalence of abnormalities found in the ophthalmology evaluation, most refractive abnormalities did not require correction, and the biomicroscopy abnormalities were mostly benign. Level III; Study of non-consecutive patients.

Prevention of Sudden Death Related to Sport: The Science of Basic Life Support-from Theory to Practice

The sudden cardiac arrest (CA) and death of athletes are dramatic and emotionally impacting events for health professionals, family, and society. Although the practice of sport participation improves general health, physical fitness, and quality of life, intense physical exercise can be a trigger for CA and sudden death occasionally in the presence of known or unknown cardiac disorders (mainly hypertrophic cardiomyopathy) and risk factors (environment, health style, family, and genetic). The present review found that sudden death associated with CA was not such a common event in competitive athletes, but it might be an underestimated event in recreational athletes. Thus, considering the exponential increase in sport participation, both in a recreational or competitive way, and the rate of sudden CA, knowledge of implementing prevention and treatment strategies is crucial. This includes preparation of health professionals and lay people in basic life support (BLS); screening and pre-participation assessment in sport programs and health education; and promotion for the recognition of CA and early completion of BLS and rapid access to automatic external defibrillator to improve the victim survival/prognosis. Thus, the purpose of this review is to provide for health professionals and lay people the most updated information, based on current guidelines, of how to proceed in an emergency situation associated with sudden CA of young adult athletes.
