Background There is strong evidence showing that sedentary behaviour time increase the risk to develop several chronic diseases and to premature death. The economic consequences of this risk have never been evaluated in France. The aim of this study was to estimate the economic burden of prolonged sedentary behaviour in France. Methods Based on individual sedentary behaviour time, relative risk to develop cardiovascular disease, colon cancer, breast cancer and all-causes of premature mortality were identified. From relative risk and prevalence of sedentary behaviour time, a population attributable fraction approach was used to estimate the yearly number of cases for each disease. Data from the National Health Insurance were used to calculate the annual average costs per case for each disease. Disease-specific and total healthcare costs attributable to prolonged sedentary behaviour time were calculated. Indirect costs from productivity loss due to morbidity and premature mortality were estimated using a friction cost approach. Results In France, 51 193 premature deaths/year appear related to a prolonged daily sedentary behaviour time. Each year prolonged sedentary behaviour cost 494 million € for the national health insurance. Yearly productivity loss due to premature mortality attributable to prolonged sedentary behaviour cost 507 million € and yearly productivity loss due to morbidity cost between 43 and 147 million €. Conclusion Significant saving and many deaths could be avoided by reducing prolonged sedentary behaviour prevalence in France. To address this issue, strong responses should be implemented to tackle sedentary behaviour, complementary to physical activity promotion.

International audience; PURPOSE: This study aimed at assessing the prevalence of adverse cardiac events, as identified in the media, in world-class athletes according to their sex and sports discipline. METHODS: All female and male’ athletes, from 30 individual Olympic sports, ranked in the international yearly top 10 between 2006-2018, were included. The name of each of them was associated in a Google search with selected key terms related to heart disease and/or acute cardiac events after their inclusion date. Global and sex-specific adverse cardiac event hazard function λ were calculated for each sport. Global and sex-specific prevalence of cardiac events were calculated, then compared (Fisher’s exact test) between all sports. RESULTS: From the 2471 athletes included, 15 cases of cardiac events (prevalence 0.61%) were reported; 2 sudden cardiac deaths (0.08%) occurred in male athletes. The other events were related to arrhythmic events (n = 13), mainly supra-ventricular arrhythmias (n = 9). All surviving athletes were able to continue their career, mostly after ablation procedure. Male endurance athletes accounted for 7 events among which 3 events occurred among short-distance triathletes. Events among women were comparatively rare (n = 4), and all were observed among short-distance triathletes. CONCLUSIONS: A relatively unexpected high prevalence of cardiac events in endurance elite athletes, was observed as compared to other sports, mainly in short-distance male and female triathletes. This raises the question of particular cardiovascular constraints in this discipline, and underlines the urge of international longitudinal follow-up studies in these kinds of athletes.

We performed a prospective cohort study of 311 outpatients with non-severe COVID-19 (187 women, median age 39 years). Of the 214 (68.8%) who completed the 6-week follow-up questionnaire, 115 (53.7%) had recovered. Others mostly reported dyspnea (n = 86, 40.2%), weight loss (n = 83, 38.8%), sleep disorders (n = 68, 31.8%), and anxiety (n = 56, 26.2%). Of those who developed ageusia and anosmia, these symptoms were still present at week 6 in, respectively, 11/111 (9.9%) and 19/114 (16.7%). Chest CT scan and lung function tests found no explanation in the most disabled patients (n = 23). This study confirms the high prevalence of persistent symptoms after non-severe COVID-19.

This article provides an overview of the recommendations from the Sports Cardiology section of the European Association of Preventive Cardiology on sports participation in individuals with valvular heart disease (VHD). The aim of these recommendations is to encourage regular physical activity including sports participation, with reasonable precaution to ensure a high level of safety for all affected individuals. Valvular heart disease is usually an age-related degenerative process, predominantly affecting individuals in their fifth decade and onwards. However, there is an increasing group of younger individuals with valvular defects. The diagnosis of cardiac disorders during routine cardiac examination often raises questions about on-going participation in competitive sport with a high dynamic or static component and the level of permissible physical effort during recreational exercise. Although the natural history of several valvular diseases has been reported in the general population, little is known about the potential influence of chronic intensive physical activity on valve function, left ventricular remodelling pulmonary artery pressure, and risk of arrhythmia. Due to the sparsity of data on the effects of exercise on VHD, the present document is largely based on clinical experience and expert opinion.

International audience; The value of echocardiography in the screening of athletes in addition to the electrocardiogram is debated and still unclear. 336 rugby players in French professional divisions (Top 14, Pro D2) were prospectively assessed with electrocardiogram and echocardiography. 75% were Caucasian, 16.4% Pacific Islanders, and 8.6% Afro-Caribbean. Six (1.8%) players had electrocardiogram abnormalities, exclusively negative T waves. Twenty-one (6.25%) of them had abnormal echocardiography findings: one possible early hypertrophic cardiomyopathy, one anomalous origin of coronary artery, two left ventricular dilatations, one isolated bicuspid aortic valve, two aortic regurgitations, and 14 ascending aortic dilatations. The median aortic diameter was modestly correlated with age: 32 mm [23-48] in players aged ≤25 years vs 33.5 mm [24-50] in those aged >25 years (P = 0.02, correlation coefficient -.01). This tendency increased with cumulative hours of weight training: 34 mm [24-50] in forwards vs 32 mm [25-44] in backs (P = 0.01); and ethnicity, with Pacific Islanders having higher values in both raw data and body surface area or height-indexed data than Afro-Caribbeans and Caucasians: 34 [25-50] vs 32 [27-48] and 33 [23-49] mm (P = 0.017); 15 [12.2-21] vs 14.8 [11-19.9] and 14.8 [10-20.9] mm/m(2) (P

BackgroundHeart rate (HR) and HR variability (HRV) indices are established tools to detect abnormal recovery status in athletes. A low HR and vagally mediated HRV index change between supine and standing positions reflected a maladaptive training stress-recovery status.ObjectivesOur study was focused on a female multistage cycling event. Its overall aim was twofold: (1) quantify the correlation between (a) the change in HR and HRV indices during an active orthostatic test and (b) subjective/objective fatigue, physical load, and training level indicators; and (2) formulate a model predicting the stress-recovery status as indexed by Δ⁢R⁢R¯ and ΔLnRMSSD (defined as the difference between standing and supine mean RR intervals and LnRMSSD, respectively), based on subjective/objective fatigue indicators, physical load, and training levels.MethodsTen female cyclists traveled the route of the 2017 Tour de France, comprising 21 stages of 200 km on average. From 4 days before the beginning of the event itself, and until 1 day after its completion, every morning, each cyclist was subjected to HR and HRV measurements, first at rest in a supine position and then in a standing position. The correlation between HR and HRV indices and subjective/objective fatigue, physical load, and training level indicators was then computed. Finally, several multivariable linear models were tested to analyze the relationships between HR and HRV indices, fatigue, workload, and training level indicators.ResultsHR changes appeared as a reliable indicator of stress-recovery status. Fatigue, training level, and Δ⁢R⁢R¯ displayed a linear relationship. Among a large number of linear models tested, the best one to predict stress-recovery status was the following: Δ⁢R⁢R¯=1,249.37+12.32V̇O2max + 0.36 km⋅week–1−8.83 HRmax−5.8 RPE−28.41 perceived fatigue with an adjusted R2 = 0.322.ConclusionThe proposed model can help to directly assess the adaptation status of an athlete from RR measurements and thus to anticipate a decrease in performance due to fatigue, particularly during a multistage endurance event.

This paper presents a brief summary of the recommendations from the Sports Cardiology section of the European Association of Preventive Cardiology (EAPC) on sports-participation in patients with coronary artery disease, coronary artery anomalies or spontaneous dissection of the coronary arteries, all entities being associated with myocardial ischaemia.1 Given the wealth of evidence supporting the benefits of exercise for primary and secondary prevention of coronary artery disease, individuals should be restricted from competitive sport only when a substantial risk of adverse event or disease progression is present. These recommendations aim to encourage regular physical activity including participation in sports and, with reasonable precaution, ensure a high level of safety for all individuals with coronary artery disease. The present document is based on available current evidence, but in most instances because of lack of evidence, also on clinical experience and expert opinion.

Summary Background The new North American guidelines for participation in competitive sport in patients with coronary artery disease (CAD) are less restrictive than previous guidelines. Aim To evaluate the incidence of major adverse cardiac events (MACE) in men with CAD who practise intensive physical activity after a stenting procedure. MACE included in-stent restenosis (SR), stent thrombosis (ST), new coronary stenosis (NCS), myocardial infarction, heart failure, cardiac arrest or cardiac death. Methods Asymptomatic men with CAD and a coronary stent who practised regular (>4 h/week) sport were included in this retrospective multicentre observational study. All patients presented with left ventricular ejection fraction ≥ 50%, no residual stenosis, and no inducible ischaemia or arrhythmias. Three groups were compared: those undertaking moderate leisure-time sport (MLS), intensive leisure-time sport (ILS) or competitive sport (CS). During follow-up, all patients had a yearly routine cardiology evaluation. Results A total of 108 men with CAD (57.3 ± 9.1 years) were included: 29 MLS, 58 ILS, and 21 CS. During follow-up (57.6 ± 46.0 months) the incidence of MACE was 15.7% (SR = 5, SR + NCS = 4, ST = 4, NCS = 4) and occurred during physical exertion in 59% of patients. ST was more frequent in the CS (n = 3) than in the MLS (n = 1) or ILS (n = 0) groups, especially in patients with bare-metal stents. Conclusions The incidence of MACE was 15.7%, and only ST was significantly more frequent in CS patients than in MLS or ILS patients. Our data support the new US guidelines for exercise eligibility in men with CAD.

International audience; Background - Pre-participation cardiovascular evaluation (PPE) aims to detect cardiac disease with sudden cardiac death (SCD) risk. No study has focused on Pacific Island athletes. Methods - A total of 2281 Pacific Island athletes were studied with (i) a questionnaire on family, personal history and symptoms, (ii) a physical examination and (iii) a 12-lead ECG. Results - 85% presented a normal history and examination. A positive family history was 1.4-1.9 fold higher in Melanesians, Polynesians and Métis than in Caucasians, while a positive personal history, abnormal symptoms and abnormal examination was 1.3 fold higher in Melanesians and Métis than in others. Neither gender nor training level had a bearing on these results. Melanesians had higher T wave inversions (TWIs) in V2-V4 leads but had no CV abnormalities. Lateral or infero-lateral TWIs were found in 6 male and in 5 highly trained athletes and cardiomyopathies were diagnosed in 3/6 athletes. Overall, 3.9% athletes were found to have a CV abnormality and 0.8% had a risk of SCD. Polynesians and males were more at risk than the others while the level of training made no difference. In athletes at risk of SCD, the main detected CV diseases were cardiomyopathies, Wolff-Parkinson-White (WPW) and severe valve lesions of rheumatoid origin. Conclusions - PPE revealed that 3.9% presented CV abnormalities. A risk of SCD was found in 0.8% with cardiomyopathies, WPW, and severe valve lesions of rheumatoid origin. Melanesians, Polynesians and male of high level of training were more at risk than others.

Contains fulltext : 209356.pdf (Publisher’s version ) (Closed access) Myocardial diseases are associated with an increased risk of potentially fatal cardiac arrhythmias and sudden cardiac death/cardiac arrest during exercise, including hypertrophic cardiomyopathy, dilated cardiomyopathy, left ventricular non-compaction, arrhythmogenic cardiomyopathy, and myo-pericarditis. Practicing cardiologists and sport physicians are required to identify high-risk individuals harbouring these cardiac diseases in a timely fashion in the setting of preparticipation screening or medical consultation and provide appropriate advice regarding the participation in competitive sport activities and/or regular exercise programmes. Many asymptomatic (or mildly symptomatic) patients with cardiomyopathies aspire to participate in leisure-time and amateur sport activities to take advantage of the multiple benefits of a physically active lifestyle. In 2005, The European Society of Cardiology (ESC) published recommendations for participation in competitive sport in athletes with cardiomyopathies and myo-pericarditis. One decade on, these recommendations are partly obsolete given the evolving knowledge of the diagnosis, management and treatment of cardiomyopathies and myo-pericarditis. The present document, therefore, aims to offer a comprehensive overview of the most updated recommendations for practicing cardiologists and sport physicians managing athletes with cardiomyopathies and myo-pericarditis and provides pragmatic advice for safe participation in competitive sport at professional and amateur level, as well as in a variety of recreational physical activities.

It is established that an intensive training results in a lower average resting heart rate. Management of bradycardia in an athlete can be difficult given the underlying mechanisms are not clearly understood. The authors reviewed the different mechanisms described in the literature, including recent advances in physiology regarding remodeling of ion channels, which may partially explain bradycardia in athletes. Sinus bradycardia amongst athletes, especially endurance focused athletes, is common but difficult to apprehend. The underlying mechanisms are observably of multifactorial origin and likely incompletely elucidated by the current body of knowledge.

ObjectivesThis study aimed to analyze the daily heart rate variability (HRV) in well-trained female cyclists during the 2017 Tour de France circuit and to relate it to the load and perceived exertion response.MethodsTen female cyclists volunteered to participate in the study. HRV was recorded with a portable heart rate monitor each morning at rest in supine (7 min.) and upright (7 min.) positions, as well as throughout each day's stage. Pre-Tour baseline HRV recordings were made, as well as during the four weeks following completion of the Tour. Exercise daily load was assessed using the training impulse score (TRIMPS). Post-exercise rate of perceived exertion (RPE) was assessed daily using the Borg CR-10 scale.ResultsThe results show a HRV imbalance, increase of sympathetic and decrease of vagal activities respectively, along the event that correlated with rate of perceived exertion (r = 0.46), training impulse score (r = 0.60), and kilometers (r = 046). The greatest change in HRV balance was observed the days after the greatest relative physical load. Mean heart rate and heart rate variability values returned to their baseline values one week after completion of the event.ConclusionsDespite incomplete recovery from day-to-day, fatigue is not summative or augmented with each successive stage and its physical load. Just one week is sufficient to restore baseline values. Heart rate and HRV can be used as a tool to strategically plan the effort of female cyclists that participate in multi-stage events.

Background Appropriate advice for the practice of sport in patients with a cardiomyopathy is a challenging issue. Recent evolution towards more comprehensive and tailored recommendations may facilitate the clinical practice. However, neither their application in real life has been evaluated nor the concordance within clinicians. Methods We submitted six cases from real life to an expert panel of eighteen clinicians (7 cardiomyopathy experts, 7 arrhythmia experts, 4 sport physicians). The six athletes had Hypertrophic (HCM, n = 3), Dilated (DCM, n = 2), Right ventricular arythmogenic (ARVC, n = 1) cardiomyopathy. Advice for the practice of sport (competitive or recreational, globally or regarding the main usual activity of the athlete or according to detailed sports classification) was collected through a structured questionnaire. Results Experts authorize the practice of the usual sport in 28% of total cases. Global concordance within experts is significant but low (Kendall W = 0.34, P Conclusions Divergent advices were observed between experts regarding sports activity that can be authorized in athletes with a cardiomyopathy. Advices were also frequently discordant with recent European recommendations. These results underline difficulties for athletes’ personalized recommendation and the need for large prospective studies to progress towards optimal management.

Aims The distinction between left ventricular (LV) dilation with mildly reduced LV ejection fraction (EF) in response to regular endurance exercise training and an early cardiomyopathy is a frequently encountered and difficult clinical conundrum. We hypothesized that exercise rather than resting measures would provide better discrimination between physiological and pathological LV remodelling and that preserved exercise capacity does not exclude significant LV damage. Methods and results We prospectively included 19 subjects with LVEF between 40 and 52%, comprising 10 ostensibly healthy endurance athletes (EA-healthy) and nine patients with dilated cardiomyopathy (DCM). In addition, we recruited five EAs with a region of subepicardial LV. Receiver operating characteristic fibrosis (EA-fibrosis). Cardiac magnetic resonance (CMR) imaging was performed at rest and during supine bicycle exercise. Invasive afterload measures were obtained to enable calculations of biventricular function relative to load (an estimate of contractility). In DCM and EA-fibrosis subjects there was diminished augmentation of LVEF (5 ± 6% vs. 4 ± 3% vs. 14 ± 3%; P = 0.001) and contractility [LV end-systolic pressurevolume ratio, LVESPVR; 1.4 (1.31.6) vs. 1.5 (1.31.6) vs. 1.8 (1.72.7); P

La Haute mer est définie juridiquement comme le domaine international situé au-delà des limites de souveraineté des États riverains. Cette province « océanique » immense, qui couvre environ 60 % de la surface de l’océan Mondial, ne fournit pourtant que 10 % de la production des pêches maritimes, parce que les eaux du large sont biologiquement pauvres, que les opérations y sont coûteuses et que seules des pêches de surface peuvent y être pratiquées. L‘exploitation repose surtout sur des espèces de haute valeur marchande, en particulier des thons tropicaux, aujourd’hui à la limite de la surexploitation. On pourrait y développer la capture de céphalopodes océaniques et de krill. Enfin les petits poissons méso- et infrapélagiques (entre 200 et 700 m de profondeur) constituent peut-être une ressource d’avenir, plutôt pour fabriquer des farines que pour nourrir directement les hommes. From a legal standpoint, the High sea is the international area which lies beyond the limits of the zone where the bordering states claim exclusive rights. This huge « oceanic province », which stretches over nearly 60% of the whole ocean surface, only provides 10% of the sea fisheries catches, because the high sea waters are biologically poor, the fishing operations are costly there, and because only pelagic fisheries can be carried out. In the High sea, exploitation chiefly lies on high value fish species, particularly on tropical tunas, although today these are on the verge of overfishing. The fishing of High sea cephalopods and krill could be developped. Lastly, small size meso- and infrapelagic fishes (living between 200 and 700 m deep) could provide future resources, but rather for fish meal reduction than for direct human food.

International audience; Aims - Intensive endurance sport practice is associated with an increased risk of atrial fibrillation (AF) in male veteran athletes. Paroxysmal AF (PAF) is the very beginning step of this disease. The description of atrial remodelling occurring at this early stage might enable to depict predictive factors of AF in veteran athletes in order to give them personalized recommendation according to their sport practice.Methods and results - Twenty-seven male endurance veteran athletes with documented PAF were retrospectively enrolled and compared with 30 control endurance athletes without documented AF, with similar training level, age, and cardiovascular risk factors. All subjects underwent a resting-electrocardiogram (ECG) to assess the electric remodelling of P-waves as well as an echocardiography, to evaluate the left and right atrial (LA, RA) anatomical and functional (assessed by 2D strain) remodelling. No difference was noted between groups for the ECG P-wave parameters. Atrial function was decreased in the PAF group, particularly the peak atrial longitudinal strain (L-ɛ-Max) of LA (29.3 ± 7.9% vs. 49.1 ± 7.8% respectively in the PAF group and in controls, P Conclusion - Atrial function analysed by strain in echocardiography is strongly associated with PAF and might enable to identify male endurance veteran athletes at risk to develop AF.

International audience; The exercise test is still a key examination in cardiology, used for the diagnosis of myocardial ischemia, as well as for the clinical evaluation of other heart diseases. The cardiopulmonary exercise test can further define functional capacity and prognosis for any given cardiac pathology. These new guidelines focus on methods, interpretation and indications for an exercise test or cardiopulmonary exercise test, as summarized below. The safety rules associated with the exercise test must be strictly observed. Interpretation of exercise tests and cardiopulmonary exercise tests must be multivariable. Functional capacity is a strong predictor of all-cause mortality and cardiovascular events. Chest pain, ST-segment changes and an abnormal ST/heart rate index constitute the first findings in favor of myocardial ischemia, mostly related to significant coronary artery disease. Chronotropic incompetence, abnormal heart rate recovery, QRS changes (such as enlargement or axial deviations) and the use of scores (based on the presence of various risk factors) must also be considered in exercise test interpretation for a coronary artery disease diagnosis. Arrhythmias or conduction disorders arising during the exercise test must be considered in the assessment of prognosis, in addition to a decrease or low increase in blood pressure during the exercise phase. When performing a cardiopulmonary exercise test, peak oxygen uptake and the volume of expired gas/carbon dioxide output slope are the two main variables used to evaluate prognosis.

Background— Pathological T-wave inversion (PTWI) is rarely observed on the ECG of healthy athletes, whereas it is common in patients with certain cardiac diseases. All ECG interpretation guidelines for use within athletes state that PTWI (except in leads aVR, III and V1 and in V1–V4 when preceded by domed ST segment in asymptomatic Afro-Caribbean athletes only) cannot be considered a physiological adaptation. The aims of the present study were to prospectively determine the prevalence of cardiac pathology in athletes presenting with PTWI, and to examine the efficacy of cardiac magnetic resonance in the work-up battery of further examinations. Methods and Results— Athletes presenting with PTWI (n=155) were investigated with clinical examination, ECG, echocardiography, exercise testing, 24h Holter ECG, and cardiac magnetic resonance. Cardiac disease was established in 44.5% of athletes, with hypertrophic cardiomyopathy (81%) the most common pathology. Echocardiography was abnormal in 53.6% of positive cases, and cardiac magnetic resonance identified a further 24 athletes with disease. Five athletes (7.2%) considered normal on initial presentation subsequently expressed pathology during follow-up. Familial history of sudden cardiac death and ST-segment depression associated with PTWI were predictive of cardiac disease. Conclusions— PTWI should be considered pathological in all cases until proven otherwise, because it was associated with cardiac pathology in 45% of athletes. Despite echocardiography identifying pathology in half of these cases, cardiac magnetic resonance must be considered routine in athletes presenting with PTWI with normal echocardiography. Although exclusion from competitive sport is not warranted in the presence of normal secondary examinations, annual follow-up is essential to ascertain possible disease expression.

Summary Background Cardiovascular events related to high-intensity sport practice are rare but dramatic. Coronary artery disease (CAD) is the leading cause of these events after the age of 35 years. The value of a maximal exercise test (ET) for detection of athletes at risk remains a matter of debate. Aim The aim of this prospective multicentre study was to clarify the medical value and cost-effectiveness of an ET in middle-aged white asymptomatic athletes who participate in high-intensity sport. Methods All athletes had a physical examination, assessment of cardiovascular risk factors, a resting electrocardiogram and an ET. In case of abnormal ET, complementary cardiovascular evaluation was performed, when requested, to detect potential cardiovascular disease. Results 1361 asymptomatic athletes (mean age 50.4 ± 9.6 years; mean training 5.1 ± 3.2 h/week; 10.4% women) with a normal resting electrocardiogram and without cardiovascular disease were consecutively included. An abnormal ET was reported in 144 subjects (94% men); this was positively related to the subject's age and cardiovascular risk level. Cardiac arrhythmias (48%) and CAD symptoms (33.3%) were mainly reported. Cardiovascular disease was confirmed in 24 cases (1.7% from the whole population; 16.7% from those with an abnormal ET) – mainly CAD (n = 12) and arterial hypertension (n = 8). Seventy athletes presented significant unexplained arrhythmias. The cost was approximately €8450 for every confirmed case of cardiovascular disease. Conclusions In this multicentre study in middle-aged athletes, a systematic ET was abnormal in 10.6% of cases. About 2% of subjects had cardiovascular disease, mainly arrhythmias and CAD. From these results, it seems that in a trained population aged >35 years, ET should be targeted at men with at least two cardiovascular risk factors, with acceptable cost-effectiveness.

Implantable cardioverter-defibrillators (ICDs) prevent sudden arrhythmic death in patients with different arrhythmogenic cardiac diseases. Because intense physical activity may trigger ventricular arrhythmias and may favour inappropriate shock delivery that impacts quality of life, current international recommendations only give clearance for moderate leisure-time physical activity to patients with an ICD. Hence, athletes are deemed non-eligible to compete with their ICD. The rationale for the current restriction from competitive sports is discussed in this review, as well as new insights that may alter these recommendations for certain sports participants in the foreseeable future. This review provides guidance for the choice of a durable lead and device system, careful programming tailored to the characteristics of the patient's physiological and pathological heart rhythms, instalment of preventive bradycardic medication, and guided rehabilitation with psychological counselling, allowing a maximum of benefit and a minimum of harm for physically active ICD patients.

Background Early repolarization pattern (ERP) associated with a risk of sudden death has recently been described. Very few studies have examined the prevalence of this pattern in a military population characterized by a predominance of young, active male subjects. Therefore, the main objective of this study was to evaluate the prevalence of ERP in a healthy military population free of heart disease but subjected to extreme and potentially arrhythmogenic physical activity. Methods This prospective, multicenter study was carried out from November 2010 to November 2011 and included 746 individuals undergoing ECG screening; 466 were men (62.4%) and 280 were women (37.5%). Each ECG was interpreted twice by trained cardiologists. Results The total prevalence of ERP was 13.8% (103/746); 16% (46/280) in women and 12% (57/466) in men (P > 0.05). It declined with age and the pattern of slurring in inferior location was the most common. Heart rate was significantly lower in military officers with ERP. Conclusions ERP was commonly found in this healthy military population. Preventing the risk of sudden death in this population requires systematic ECG screening, medical history analysis and clinical examination to identify symptomatic patients.

Victims are usually young and apparently healthy, and while many of these deaths remain unexplained, a substantial number of victims harbour an underlying and potentially detectable cardiovascular (CV) disease.1–4 The vast majority of these events are due to malignant tachyarrhythmias, usually ventricular fibrillation (VF) or ventricular tachycardia (VT) degenerating into ventricular fibrillation (VF), occurring in individuals with arrhythmogenic disorders (e.g. hypertrophic cardiomyopathy, arrhythmogenic cardiomyopathy, channelopathies). Intensive exercise training and competitive sport participation is a trigger that may favour insurgence of ominous ventricular tachyarrhythmias in predisposed individuals.5 Consequently, there is a great interest in early identification of at-risk individuals for whom appropriate treatment, followed or not by physical activity adjustment, may be implemented to minimize the risk of SCD. However, the role of pre-participation evaluation (PPE) in athletes as a feasible and efficient strategy to identify individuals at risk has remained controversial. …

International audience; Head up tilt test is a well-known medical procedure used to diagnose vasovagal syncope. Several studies have focused on the early prediction of the outcomes of this test to predict syncope before its occurrence. Therefore, the evaluation of the dynamic interactions between several cardiovascular variables can play an important role to improve our understanding on the function of the baroreflex control of arterial blood pressure and can help to enhance the prediction performance. In this aim, the smoothed pseudo-Wigner–Ville distribution (SPWD) approach was used to characterize the time–frequency relationship between time series extracted from ECG (RR-interval) and blood pressure (amplitudes of the systolic blood pressure, the peak amplitude of the first derivative of the blood pressure, dP/dt and the variability of the pulse transit time, PTT). Two new indexes quantifying the relationship between time series were introduced. The first index computed the distribution of time–frequency coherence between 2 time series in different frequency bands and the second one computed the scalar product of the time–frequency spectra of these time series. This approach was applied to predict the outcome of a head up tilt test (HUTT) based on the first 15 min, to early detect subjects that would faint or not during this test. Our results demonstrate that the strongest parameter to predict HUTT result is the dynamic interaction between RR-interval and the amplitude of systolic blood pressure (AmpS), using the scalar product of the auto time–frequency spectra computed with SPWD (sensitivity: 87.5%; specificity: 93.8%). This study also shows that in high frequency band, the similarity between the RR-interval and the AmpS time series is higher during the first 15 min of HUTT in subjects that would faint. As a clinical viewpoint, these results could bring new perspectives to better understand physiological mechanisms during HUTT and syncope, which are still unclear and could lead also to a reduction of HUTT duration, which is currently between 30 and 45 min

International audience; Aims Rest echocardiography plays a role in hypertrophic cardiomyopathy (HCM) diagnosis and risk stratification because left atrial enlargement, severe left ventricle (LV) hypertrophy, and rest LV outflow tract (LVOT) gradients ≥50 mmHg are sudden cardiac death risk factors that have been highlighted in recent guidelines. Conversely, the lack of evidence makes that exercise-echocardiography findings play a limited role. In clinical practice, LVOT gradient, but also mitral regurgitation (MR) or pulmonary pressure, seems relevant parameters to look for, during the exercise. Therefore, we sought to determine whether exercise-induced changes in myocardial and valvular functions could improve HCM risk stratification. Methods and results Consecutive primitive HCM patients with a preserved LV ejection fraction underwent standardized exercise echocardiography (including the assessment of myocardial function, dynamic left intraventricular gradient, and valvular regurgitations) at baseline and were clinically followed for a median of 29.3 months. The primary endpoint was a composite criterion that included death from any cause, cardiorespiratory arrest, and hospitalization for a cardiovascular event. A total of 126 patients were included. Eighteen patients reached the primary endpoint. According to univariate Cox regression analysis, exercise LVOT gradient ≥50 mmHg [hazard ratio (HR) = 3.31, P = 0.01] and significant (≥2/4) exercise MR (HR = 3.64, P , 0.01) were associated with the primary endpoint. Patients with significant MR had significantly higher rest and exercise LVOT gradients (P= 0.001 and P= 0.001) and larger left atria volumes (P , 0.001). Conclusion Significant exercise-induced MR appears to significantly impact the prognoses of HCM patients, and it is also associated with higher LVOT rest and exercise gradients,. © The Author 2015.

Background— Ethnicity is an important determinant of cardiovascular adaptation in athletes. Studies in black male athletes reveal a higher prevalence of electric repolarization and left ventricular hypertrophy than observed in white males; these frequently overlap with those observed in cardiomyopathy and have important implications in the preparticipation cardiac screening era. There are no reports on cardiac adaptation in highly trained black females, who comprise an increasing population of elite competitors. Methods and Results— Between 2004 and 2009, 240 nationally ranked black female athletes (mean age 21±4.6 years old) underwent 12-lead ECG and 2-dimensional echocardiography. The results were compared with 200 white female athletes of similar age and size participating in similar sports. Black athletes demonstrated greater left ventricular wall thickness (9.2±1.2 versus 8.6±1.2 mm, P P =0.008) than white athletes. Eight black athletes (3%) exhibited a left ventricular wall thickness >11 mm (12 to 13 mm) compared with none of the white athletes. All athletes revealed normal indices of systolic and diastolic function. Black athletes exhibited a higher prevalence of T-wave inversions (14% versus 2%, P P 1 through V 3 ). Conclusions— Systematic physical exercise in black female athletes is associated with greater left ventricular hypertrophy and higher prevalence of repolarization changes than in white female athletes of similar age and size participating in identical sporting disciplines. However, a maximal left ventricular wall thickness >13 mm or deep T-wave inversions in the inferior and lateral leads are rare and warrant further investigation.

Contains fulltext : 89482.pdf (Publisher’s version ) (Closed access) Cardiovascular remodelling in the conditioned athlete is frequently associated with physiological ECG changes. Abnormalities, however, may be detected which represent expression of an underlying heart disease that puts the athlete at risk of arrhythmic cardiac arrest during sports. It is mandatory that ECG changes resulting from intensive physical training are distinguished from abnormalities which reflect a potential cardiac pathology. The present article represents the consensus statement of an international panel of cardiologists and sports medical physicians with expertise in the fields of electrocardiography, imaging, inherited cardiovascular disease, cardiovascular pathology, and management of young competitive athletes. The document provides cardiologists and sports medical physicians with a modern approach to correct interpretation of 12-lead ECG in the athlete and emerging understanding of incomplete penetrance of inherited cardiovascular disease. When the ECG of an athlete is examined, the main objective is to distinguish between physiological patterns that should cause no alarm and those that require action and/or additional testing to exclude (or confirm) the suspicion of an underlying cardiovascular condition carrying the risk of sudden death during sports. The aim of the present position paper is to provide a framework for this distinction. For every ECG abnormality, the document focuses on the ensuing clinical work-up required for differential diagnosis and clinical assessment. When appropriate the referral options for risk stratification and cardiovascular management of the athlete are briefly addressed. 01 januari 2010

Summary Aims To compare the impact of three patient counselling strategies for lifestyle changes and to assess the safety and efficacy of ezetimibe on top of statin therapy in hypercholesterolemic high risk patients. Methods Open, cluster randomized 3-parallel group trial. Physicians were randomized between patient motivation on: diet or physical exercise or both. Counselling was adapted to the patient's baseline Prochaska stage of change. High cardiovascular risk patients, with LDL-C above or equal to 3 mmol/L despite statin therapy for at least 3 months, were enrolled. Ezetimibe (10 mg/day) and patient counselling were started at the same time. Target goal was defined as total cholesterol less than 5 mmol/L and LDL-C above 3 mmol/L. Results Overall 428 physicians enrolled 1496 patients. At baseline, LDL-C was 3.9 ± 0.9 mmol/L and total cholesterol was 6.1 ± 1.1 mmol/L. LDL-C decreased by −30.4 ± 19.3% and 869 (62%) patients achieved target goal. No difference was shown between randomisation groups. However, improvements in diet consumption patterns were more easily obtained than improvement in physical activity stage of change in non-active patient at baseline. Conclusions The marked short-term impact (−30%) on LDL-C, although similar between the three groups, slightly exceeds usual LDL-C reductions achieved by this dose of ezetimibe. Decreasing fat consumption seems easier than increasing physical activity. This study confirms the good efficacy, short-term tolerability and safety of ezetimibe on top of statins.

Background It is commonly acknowledged that the ability to use the ankle–brachial index (ABI), a reliable way to diagnose atherosclerosis, decreases with age in the general population. The aim of this study was to determine the relationship between resting ABI and age in different populations. Methods 674 physically active participants with (active high risk, ACTHR) or without (active low risk, ACTLR) cardiovascular risk factors or/and sedentary (SED) subjects, aged 20–70 years. Systolic arterial pressure was recorded at rest and simultaneously with automatic sphygmomanometers at the arms and ankles. ABI was calculated as the ratio of the lowest, highest or mean ankle pressure to the highest arm pressure. Results Proportion of ABImin0.90) but was significantly lower in SEDHR compared with all active participants (p

We are pleased to address questions raised by Wheeler and colleagues concerning the identified high prevalence of hypertrophic cardiomyopathy (HCM) in our recent publication.1 The aim of our study was to prospectively determine the prevalence of cardiac pathology in athletes presenting with pathological T-wave inversion (PTWI), and to examine the efficacy of cardiac magnetic resonance in the further examination workup. Although Wheeler et al consider a PTWI prevalence of 2.4% high, it is nearly identical (2.3%) to that reported from a large, unselected population of 32 652 individuals.2 Indeed, ethnicity is known to impact T-wave inversion (TWI) rates, with black athletes and controls demonstrating TWI rates of 4.1% and 3.4% in the lateral leads only.3 Wheeler et al request outcome data in athletes with lone PTWI (ie, without ST …

Background— The phenotype of individuals with hypertrophic cardiomyopathy (HCM) who exercise regularly is unknown. This study characterized the clinical profile of young athletes with HCM. Methods and Results— The electrical, structural, and functional cardiac parameters from 106 young (14–35 years) athletes with HCM were compared with 101 sedentary HCM patients. A subset of athletes with HCM exhibiting morphologically mild (13–16 mm), concentric disease was compared with 55 healthy athletes with mild physiological left ventricular hypertrophy (LVH). Most athletes with HCM (96%) exhibited T-wave inversion and had milder LVH (15.8±3.4 mm versus 19.7±6.5 mm, P P E / E ′ 7.9±2.4 versus 10.7±3.9, P 54 mm, 87% had a left atrium ≤40, and 100% had an E / E ′ Conclusions— Athletes with HCM exhibit less LVH, larger left ventricular cavities, and normal indices of diastolic function compared with sedentary patients. Only a minority of athletes with HCM constitute the conventional gray zone of mild, concentric LVH. In this minority, conventional echocardiographic parameters alone are insufficient to differentiate HCM from physiological LVH and should be complemented by additional structural and functional assessments to minimize the risk of false reassurance.

Item does not contain fulltext There are large variations in the incidence, registration methods and reported causes of sudden cardiac arrest/sudden cardiac death (SCA/SCD) in competitive and recreational athletes. A crucial question is to which degree these variations are genuine or partly due to methodological incongruities. This paper discusses the uncertainties about available data and provides comprehensive suggestions for standard definitions and a guide for uniform registration parameters of SCA/SCD. The parameters include a definition of what constitutes an 'athlete', incidence calculations, enrolment of cases, the importance of gender, ethnicity and age of the athlete, as well as the type and level of sporting activity. A precise instruction for autopsy practice in the case of a SCD of athletes is given, including the role of molecular samples and evaluation of possible doping. Rational decisions about cardiac preparticipation screening and cardiac safety at sport facilities requires increased data quality concerning incidence, aetiology and management of SCA/SCD in sports. Uniform standard registration of SCA/SCD in athletes and leisure sportsmen would be a first step towards this goal.
