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., (Published on behalf of the European Society of Cardiology.

Improved clinical care has led to an increase in the number of adults with congenital heart disease (CHD) engaging in leisure time and competitive sports activities. Although the benefits of exercise in patients with CHD are well established, there is a low but appreciable risk of exercise-related complications. Published exercise recommendations for individuals with CHD are predominantly centred on anatomic lesions, hampering an individualized approach to exercise advice in this heterogeneous population. This document presents an update of the recommendations for competitive sports participation in athletes with cardiovascular disease published by the Sports Cardiology & Exercise section of the European Association of Preventive Cardiology (EAPC) in 2005. It introduces an approach which is based on the assessment of haemodynamic, electrophysiological and functional parameters, rather than anatomic lesions. The recommendations provide a comprehensive assessment algorithm which allows for patient-specific assessment and risk stratification of athletes with CHD who wish to participate in competitive sports., (Published on behalf of the European Society of Cardiology.

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.

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.

Background: Aortic or mitral valvular regurgitation (left cardiac valvular regurgitation, LCVR) of less than second-degree (< degree II) occasionally found in competitive athletes is of questionable relevance. Precisely detectable by echocardiography there is scarce published data that clarifies cardiopulmonary capacity or any limitations LCVR < degree ll may cause., Methods: In this single-centre study we consecutively recruited highly trained athletes (n= 14) with LCVR < degree ll detected in 2D echo. Not included were athletes with multi- or right-cardiac valvular dysfunction and structural heart disease other than bicuspid aortic valve or mitral valve prolaps. Target parameters were determined by 2D echo and spiroergometry., Results: There were no significant differences with regard to age and body mass index. Echocardiographically determined muscle mass index was increased in both groups (134 14.7 vs 129.6+/-27.5; P=0.69), whereas the left-ventricular end-diastolic diameter index was significant higher in the LCVR < degree II group (27.3 +/- 1.3 vs 25.2 +/- 2.4; P = 0.04). However, there were no significant differences with regard to (oxygen uptake) V02, at baseline (athletes with LCVR < degree II 5.7 +/- 0.9 vs controls 5 +/- 0.96, P= 0.06), at the anaerobic threshold (athletes with LCVR < degree II 47.3 +/-8.4 vs controls 47.4 +/- 5, P= 0.97) and maximally (VO2max; athletes with LCVR < degree II 57.7 6.3 vs controls 57.1 +/- 5.1, P= 0.81). Neither levels of lactate nor of brain natriuretic peptide differed significantly., Conclusion: High level athletes presenting with aortic or mitral regurgitation < degree II in are not disadvantaged with regard to their cardiopulmonary capability.

The key challenge in athlete's screening is the distinction between abnormal and normal which is hindered by the fact that the adaptation to sports activity in endurance athletes is different to that in power athletes. Especially cardiomyopathies provoke changes in ECG and echocardiography (echo) at an early stage when clinical symptoms are absent. ECG and echo data and their relationship to fitness peculiar to top handball players have never been described. We studied 291 male first league handball players (32 Olympians/47 national players) (25.3±4.4 years). Check up consisted of ECG, spiroergometry and echocardiography. None had T-wave inversions, 3.1% showed early repolarisation abnormalities in the precordial leads. Sokolow-Lyon voltage criterion for left ventricular hypertrophy was positive in 19.3%. Spiroergometry showed a maximum oxygen uptake (peakVO₂) of 50.3±7.7 ml/min/kg body weight. LVmass was increased in comparison to normal values. There was a correlation between peakVO₂ and LVindex (p<0.001, r=0.341), (LVmass/peak VO₂ p=0.053, r=0.125). A relationship between cardiac dimensions and peakVO₂ could not be confirmed. In professional handball players early repolarisation abnormalities were less frequent and LVmass was increased when compared with soccer players. The need for normal values for different types of sports is crucial to guarantee a proper evaluation of athletes., (© Georg Thieme Verlag KG Stuttgart · New York.)

Background and Objective: Echocardiographic Tissue Doppler Imaging (TDI) has been proposed for the differentiation of pathological left ventricular hypertrophy (e. g. hypertrophic cardiomyopathy, HCM) and physiologic left ventricular hypertrophy (athlete's heart). The aim of this study was the TDI analysis of the systolic (S') and early diastolic (E') velocities in patients (pts.) with non-obstructive hypertrophic cardiomyopathy (HCM) and in top-level athletes in consideration of the previously published cut-off values (S' < 9 cm/s, E' < 9 cm/s)., Patients and Methods: Pulsed-wave TDI of the systolic and early-diastolic velocities was performed at the lateral and septal mitral annulus in the four-chamber view in 17 HCM pts (12 men; mean age 44 ± 16 years) and 80 consecutive athletes (80 men; mean age 26 ± 5 years)., Results: Pts with HCM showed significantly decreased systolic velocities of the septal (S' septal: 5.1 ± 1.2 cm/s versus 9.5 ± 1.5 cm/s, p < 0.001) and lateral mitral annulus (S' lateral: 6.4 ± 2.0 cm/s vs. 10.5 ± 2.1 cm/s, p < 0.001). The early diastolic velocity of the mitral annulus E' was significantly decreased in HCM, too (E' septal: 5.9 ± 2.2 cm/s vs. 13.1 ± 2.9 cm/s, p < 0.001; E' lateral: 8.2 ± 3.0 cm/s vs. 16.5 ± 3.4 cm/s, p < 0.001)., Conclusion: Tissue Doppler Imaging of the systolic and early diastolic velocity of the mitral annulus might be helpful as a promising additional method for the echocardiographic differentiation between pathological and physiologic left ventricular hypertrophy., (© Georg Thieme Verlag KG Stuttgart · New York.)

Objective: Cardiac adaptation to sports activity in endurance athletes is considerably different from that in power athletes. The effects of a high-level team sport like handball, one of the most popular sports in the world, performed at a younger age, on cardiac rhythm in individuals above the age of 50 have not been investigated to date., Methods: Thirty-three former top-level handball players from the first German league (6 former world champions and numerous Olympians) (57.5 +/- 5.5 y) joined our screening programme for former athletes and underwent electrocardiography, echocardiography and spiroergometry. Data were compared to 24 sedentary healthy controls., Results: Ten of the 33 athletes suffered from atrial fibrillation (AF). Left ventricular diameter was 53.68 +/- 4.88 mm in the athletes group and 50.58 +/- 4.12 mm in the healthy controls. Analysing the subgroups of handball players ('AF group' and 'non-AF group'), spiroergometry showed oxygen consumption at the anaerobic threshold of 27.54 +/- 6.77 ml/kg/min in the AF group and 31.24 +/- 10.33 ml/kg/min in the non-AF group (P = 0.228). Absolute left atrial diameter was 44.34 +/- 4.41 mm in the AF group (non-AF group 38.94 +/- 3.77 mm, P < 0.001) (healthy controls 37.54 +/- 4.34 mm, compared with all athletes P = 0.015). In all individuals left ventricular wall thickness was within normal limits. However, myocardial walls were thicker in the AF group (11.28 +/- 1.83 mm) than in the non-AF group (9.44 +/- 1.26 mm, P = 0.002). Athletes in the AF group (187.6 +/- 6.42 cm) were significantly taller than in the non-AF group (180.91 +/- 7.31 cm, P = 0.018)., Conclusion: Not only endurance training, but also sports activity with a relevant static component, like team handball, might predispose for AF above the age of 50. LA size, height and myocardial wall thickness seem to affect the risk of developing AF. More data in non-endurance sports are mandatory to confirm this hypothesis.

Mass gathering events in sports arenas create challenges regarding the cardiovascular safety of both athletes and spectators. A comprehensive medical action plan, to ensure properly applied cardiopulmonary resuscitation, and wide availability and use of automated external defibrillators (AEDs), is essential to improving survival from sudden cardiac arrest at sporting events. This paper outlines minimum standards for cardiovascular care to assist in the planning of mass gathering sports events across Europe with the intention of local adaptation at individual sports arenas, to ensure the full implementation of the chain of survival.

Background and Objective: Echocardiographic tissue Doppler imaging (TDI) has been proposed for the differentiation of physiologic left ventricular hypertrophy and pathologic left ventricular hypertrophy in athletes. In addition, cutoff values for systolic (S'<9 cm/s) and early diastolic (E'<9 cm/s) myocardial velocities had been defined. The aim of our study was the analysis of the morphologic cardiac changes by standard echocardiography, and the myocardial velocities S' and E' by TDI in top-level handball players with respect to the predefined cutoff values., Patients and Methods: Pulsed-wave TDI of the systolic and early diastolic velocities was performed at the lateral and septal mitral annulus (MA) in the four-chamber view in 100 athletes (100 Caucasian men; professional handball players of the first German handball league and the German national team; mean age 25.8+/-4.8 years)., Results: Global and regional left ventricular systolic function was normal in all athletes. They showed an eccentric hypertrophy of the left ventricle (LV), which was characterized by an increased mass of the LV (287.3+/-58.4 g), and an increased end diastolic diameter of the LV (LVEDD: 58+/-5.9 mm), but no echomorphologic signs of pathologic hypertrophy or hypertrophic cardiomyopathy. TDI showed a systolic velocity S' of the MA of 9.3+/-1.5 cm/s at the septal and 10.5+/-2.1 at the lateral MA. Ten of the 100 athletes showed a S'<9 cm/s at both sides of the MA. TDI showed an early diastolic velocity E' of the MA of 13.2+/-2.8 cm/s at the septal and of 16.6+/-3.4 cm/s at the lateral MA. None of the 100 athletes showed reduced systolic or early diastolic velocities below the proposed cutoff values (S' and E'<9 cm/s) at any sides of the MA., Conclusion: Our study provides further insights into systolic and diastolic function as assessed by TDI in top-level handball players. Owing to the large cohort of individuals, our findings might be helpful as reference values for the echocardiographic assessment of handball players, who are performing a moderate static and high dynamic sport.

Physical check-ups among athletes with valvular heart disease are of significant relevance. In athletes with mitral valve stenosis the extent of allowed physical activity is dependant on the size of the left atrium and the severity of the valve defect. Patients with mild-to-moderate mitral valve regurgitation can participate in all types of sport associated with low and moderate isometric stress and moderate dynamic stress. Patients under anticoagulation should not participate in any type of contact sport. Asymptomatic athletes with mild aortic valve stenosis can take part in all types of sport, as long as left ventricular function and size are normal, a normal response to exercise at the level performed during athletic activities is present and there are no arrhythmias. Asymptomatic athletes with moderate aortic valve stenosis should only take part in sports with low dynamic and static stress. Aortic valve regurgitation is often present due to connective tissue disease of a bicuspid valve. Athletes with mild aortic valve regurgitation, with normal end diastolic left ventricular size and systolic function can participate in all types of sport. A mitral valve prolapse is often associated with structural diseases of the myocardium and endocardium. In patients with mitral valve prolapse Holter-ECG monitoring should also be performed to detect significant arrhythmias. All athletes with known valvular heart disease, a previous history of infective endocarditis and valve surgery should receive endocarditis prophylaxis before dental, oral, respiratory, intestinal and genitourinary procedures associated with bacteraemia. Sport activities have to be avoided during active infection with fever.

The 1996 American Heart Association consensus panel recommendations stated that pre-participation cardiovascular screening for young competitive athletes is justifiable and compelling on ethical, legal, and medical grounds. The present article represents the consensus statement of the Study Group on Sports Cardiology of the Working Group on Cardiac Rehabilitation and Exercise Physiology and the Working Group on Myocardial and Pericardial diseases of the European Society of Cardiology, which comprises cardiovascular specialists and other physicians from different European countries with extensive clinical experience with young competitive athletes, as well as with pathological substrates of sudden death. The document takes note of the 25-year Italian experience on systematic pre-participation screening of competitive athletes and focuses on relevant issues, mostly regarding the relative risk, causes, and prevalence of sudden death in athletes; the efficacy, feasibility, and cost-effectiveness of population-based pre-participation cardiovascular screening; the key role of 12-lead ECG for identification of cardiovascular diseases such as cardiomyopathies and channelopathies at risk of sudden death during sports; and the potential of preventing fatal events. The main purpose of the consensus document is to reinforce the principle of the need for pre-participation medical clearance of all young athletes involved in organized sports programmes, on the basis of (i) the proven efficacy of systematic screening by 12-lead ECG (in addition to history and physical examination) to identify hypertrophic cardiomyopathy-the leading cause of sports-related sudden death-and to prevent athletic field fatalities; (ii) the potential screening ability in detecting other lethal cardiovascular diseases presenting with ECG abnormalities. The consensus document recommends the implementation of a common European screening protocol essentially based on 12-lead ECG.
