Abstract
BACKGROUND Sudden cardiac death (SCD) is an important cause of exercise-associated fatalities in Thoroughbred racehorses. Equine deaths share similarities with fatalities in human athletes that result from inherited cardiac disease. Whilst genetic causes have been postulated in horses, these have not been confirmed and heritability of SCD has not previously been estimated in Thoroughbred racehorses. OBJECTIVES To determine the heritability of SCD in a sample population of Thoroughbred racehorses. STUDY DESIGN Retrospective case-control study. METHODS Steward and post-mortem reports of Thoroughbred racehorses in Australia between 2007 and 2020 were reviewed to identify horses with SCD. Control horses were randomly selected from races in which SCD occurred or from races on the date of the case fatality. A five-generation integrated pedigree chart was collected for each horse. Estimates of heritability were obtained using an animal model in the ASReml-R program with variance components estimated assuming SCD was normally distributed, and on the logit transformed scale. Inbreeding coefficients were calculated and the risk of producing SCD-affected progeny was calculated for stallions that sired ≥5 individuals in the case-control population. RESULTS Ninety-three horses with SCD and 465 control horses were identified. Heritability on the underlying scale was 0.15 ± 0.09 (logit animal) and 0.24 ± 0.12 (normal animal). Inbreeding coefficients were not significantly different between groups. Of the 16 first generation sires that appeared ≥5 times in the case-control data set, two sires more frequently produced affected progeny (OR 7.95-10.41). MAIN LIMITATIONS Challenges in definitively confirming SCD may lead to misclassification of some cases. Some control horses may have not been exposed to environmental influences of SCD. Case numbers are low and the studied population may not represent the entire Thoroughbred genetic pool. CONCLUSION The heritability of SCD in this population was relatively low. However, individual stallions appear more likely to produce affected progeny. Further studies are required to understand the genetic and environmental influences that contribute to disease expression.

Abstract
OBJECTIVE To evaluate the association between vitamin D status and CV disease after COVID-19 in college athletes. DESIGN Retrospective cohort study. SETTING National College Athletic Association Division-I college athletes from a single academic institution. PATIENTS A total of 157 athletes (60 female; median age: 20 years) from 9 sports with a positive SARS-CoV-2 test, cardiac magnetic resonance imaging (CMR), and vitamin D level. INDEPENDENT VARIABLES Serum 25-hydroxyvitamin D level (primary); age, sex (regression models). MAIN OUTCOMES MEASURES Differences in age, sex, race, ethnicity, myocarditis, pericarditis, and CMR metrics by vitamin D status were analyzed. Regression models were used to assess the relationship between vitamin D status and CMR metrics accounting for age and sex. RESULTS Low vitamin D (LVD) was found in 33 (21.0%) of athletes, particularly Black males (P < 0.001). Athletes with LVD had higher biventricular and lower mid-ventricular extracellular volumes, but these differences were not significant when corrected for age and sex. Athletes with LVD had higher left ventricle (LV) mass (P < 0.001) and LV mass index (P = 0.001) independent of age and sex. Differences in global circumferential strain were noted but are likely clinically insignificant. Vitamin D status did not associate with myocarditis and pericarditis (P = 0.544). CONCLUSIONS LVD is common in athletes, particularly in Black males. Although athletes with LVD had higher LV mass, cardiac function and tissue characterization did not differ by vitamin D status. Future studies are needed to determine if the differences in LV mass and LV mass index by vitamin D status are clinically significant. This study suggests that vitamin D status does not impact the development of myocarditis or pericarditis after COVID-19 infection.

Abstract
Prolonged and intensive exercise induces remodeling of all four cardiac chambers, a physiological process which is coined as the “athlete’s heart”. This cardiac adaptation, however, shows overlapping features with non-ischemic cardiomyopathies, such as dilated, arrhythmogenic and hypertrophic cardiomyopathy, also associated with athlete’s sudden cardiac death. Cardiac magnetic resonance (CMR) is a well-suited, highly reproducible imaging modality that can help differentiate athlete’s heart from cardiomyopathy. CMR allows accurate characterization of the morphology and function of cardiac chambers, providing full coverage of the ventricles. Moreover, it permits an in-depth understanding of the myocardial changes through specific techniques such as mapping or late gadolinium enhancement. In this narrative review, we will focus on the certainties and uncertainties of the role of CMR in sports cardiology. The main aspects of physiological adaptation due to regular and intensive sports activity and the application of CMR in highly trained athletes will be summarized.

Abstract
BACKGROUND: Notwithstanding how physical exercise lessens cardiovascular and all-cause mortality, young and active athletes might have cardiovascular risk factors or fundamental cardiovascular diseases (CVDs), putting them at increased risk for sudden cardiac death during times of strenuous exercise.
AIM: The study aimed to assess the cardiovascular risk profile possessed by Indonesian athletes.
METHODS: This research was a quantitative study using a cross-sectional design, involving 234 Indonesian athletes (163 men and 71 women) from three sports, including football, basketball, and swimming. Data were collected between December 2020 to March 2021 using the Jakarta Cardiovascular Risk Score instrument adapted from the Framingham risk score. Descriptive statistics were utilized to dissect data information for frequency distribution, percentage, mean, and standard deviation.
RESULTS: Most of the participants in this study had excessive weekly exercise duration (more than 255 minutes/week) (n=177 athletes, 75.64%). Twenty-one participants (8.97%) had a higher MAP more than normal, and 51 participants (21.79%) had overweight BMI. In addition, 142 participants (60.68%) had a cardiovascular genetic disease from their parents (family history) and most of the participants also were active smokers (n=150, 64.10%). Based on the Jakarta Cardiovascular Risk Score, the Indonesian athletes who participated in this study had a mean cardiovascular risk of -1.5 (SD= 3.088, min-max= (-7) – 6). Most of the participants had low cardiovascular risk (n= 193, 82.48%). However, some participants had moderate and high cardiovascular risk, 32 (13.67%) and 9 (3.85%), respectively.
CONCLUSION: Most of the participants had low cardiovascular risk, however some of the participants had moderate and high cardiovascular risk.

Abstract
Human athletic performance is a complex phenotype influenced by environmental and genetic factors, with most exercise-related traits being polygenic in nature. The aim of this article is to outline some of the challenge faced by sports genetics as this relatively new field moves forward. This review summarizes recent advances in sports science and discusses the impact of the genome, epigenome and other omics (such as proteomics and metabolomics) on athletic performance. The article also highlights the current status of gene doping and examines the possibility of applying genetic knowledge to predict athletes' injury risk and to prevent the rare but alarming occurrence of sudden deaths during sporting events. Future research in large cohorts of athletes has the potential to detect new genetic variants and to confirm the previously identified DNA variants believed to explain the natural predisposition of some individuals to certain athletic abilities and health benefits. It is hoped that this article will be useful to sports scientists who seek a greater understanding of how genetics influences exercise science and how genomic and other multi-omics approaches might support performance analysis, coaching, personalizing nutrition, rehabilitation and sports medicine, as well as the potential to develop new rationale for future scientific investigation.

Abstract
Sudden cardiac death (SCD) is a tragic incident accountable for up to 50% of deaths from cardiovascular disease. Sports-related SCD (SrSCD) is a phenomenon which has previously been associated with both competitive and recreational sport activities. SrSCD has been found to occur 5-33-fold less frequently in women than in men, and the sex difference persists despite a rapid increase in female participation in sports. Establishing the reasons behind this difference could pinpoint targets for improved prevention of SrSCD. Therefore, this review summarizes existing knowledge on epidemiology, characteristics, and causes of SrSCD in females, and elaborates on proposed mechanisms behind the sex differences. Although literature concerning the aetiology of SrSCD in females is limited, proposed mechanisms include sex-specific variations in hormones, blood pressure, autonomic tone, and the presentation of acute coronary syndromes. Consequently, these biological differences impact the degree of cardiac hypertrophy, dilation, right ventricular remodelling, myocardial fibrosis, and coronary atherosclerosis, and thereby the occurrence of ventricular arrhythmias in male and female athletes associated with short- and long-term exercise. Finally, cardiac examinations such as electrocardiograms and echocardiography are useful tools allowing easy differentiation between physiological and pathological cardiac adaptations following exercise in women. However, as a significant proportion of SrSCD causes in women are non-structural or unexplained after autopsy, channelopathies may play an important role, encouraging attention to prodromal symptoms and family history. These findings will aid in the identification of females at high risk of SrSCD and development of targeted prevention for female sport participants.

Abstract
Athletic participation at all levels of proficiency is an encouraged activity. Physicians evaluating athletes are tasked with assessing the benefits and risks of participating in vigorous physical activity and should engage in shared decision making with the athlete. Identifying the neurologic sequelae is an essential part of the assessment that is often not covered. This chapter will review the association of a wide range of cardiac disorders that can be related to or associated with subsequent neurologic sequelae, along with a brief overview of recommendations for management. Prevalent neurological complications of cardiac disease in athletes include stroke and seizures. There are also certain channelopathies that result in concurrent cardiac dysrhythmias and epilepsy. In addition, physiologic cardiac rhythm changes and the athlete's heart are discussed in the context of the differential diagnoses of subsequent cardiac and neurologic disease. The primary objective of this chapter is to prepare the physician for accurate recognition of cardiac disease in athletes that could result in neurologic complications if not diagnosed and managed early on.
