| On the other hand sportsmen with an athlete's heart are reassured and able to continue as competitors. This approach has been supported by imaging studies that have demonstrated mild impairment of myocardial relaxation and an increase, albeit modest, in the extracellular cardiac matrix in genotype positive/phenotype negative patients.31,32 Conversely, US studies in adolescents who were genotype positive/phenotype negative have revealed a low penetrance of disease over a 12-year follow-up period with only 2 of 36 (6 %) patients affected.33 As such, the USA permits participation in all sports for these individuals, including those with high dynamic and high static components, though it advocates regular surveillance. Galderisi M, Cardim N, D'Andrea A, Bruder O, Cosyns B, Davin L, Donal E, Edvardsen T, Freitas A, Habib G, Kitsiou A, Plein S, Petersen SE, Popescu BA, Schroeder S, Burgstahler C, Lancellotti P. Eur Heart J Cardiovasc Imaging. Clinical meaning of isolated increase of QRS voltages in hypertrophic cardiomyopathy versus athlete's heart. Eligibility and disqualification recommendations for competitive athletes with cardiovascular abnormalities: task force 3: hypertrophic cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy and other cardiomyopathies, and myocarditis: a scientific statement from the American Heart Association and American College of Cardiology. doi: 10.1371/journal.pone.0166009. This results in the heart being less able to pump blood effectively. Hypertrophic cardiomyopathy (HCM) is reported historically as the most common cause of SCD in athletes younger than 35 years of age. Hypertrophic cardiomyopathy (HCM) 1, 2 is a major focus of this document given that it is the single most common cause of sudden death in young competitive athletes in the United States, responsible for at least one-third of these events. It can also cause a partial obstruction to blood flow in the left ventricle, producing a condition similar to aortic stenosis. This site needs JavaScript to work properly. There is an overlap between this type of physiologic cardiac hypertrophy and mild forms of hypertrophic cardiomyopathy (HCM), the most common genetic disorder of the cardiovascular system with a prevalence of 0.2%. If the diagnosis could not be stated using echocardiography, methods like cardiac-MRI, metabolic exercise testing, histological studies of endomyocardial biopsies and genetic testing can provide further information. The LV end-diastolic dimension in healthy athletes ranges between 55 and 70 mm20 as opposed to those with HCM who generally have an LV cavity dimension of <50mm. Most studies are based on comparisons of clinical tests between healthy unaffected athletes and sedentary individuals with HCM. Left Ventricular Dimensions in Athletes with HCM. Hypertrophic cardiomyopathy and athlete’s heart represent two distinct conditions, where pathologic processes or physiologic adaptations, respectively, result in an increase of heart wall dimensions (1), (2). HCM is commonly characterized by asymmetric left ventricular hypertrophy with a reduced LV-diameter. Differentiation between pathologic and physiologic left ventricular hypertrophy by tissue doppler assessment of long-axis function in patients with hypertrophic cardiomyopathy or systemic hypertension and in athletes. Ho CY, López B, Coelho-Filho OR, et al. The ability to delineate LV hypertrophy, reveal underlying fibrosis or utilize more novel techniques such as T1 mapping give CMR a unique position in the armamentarium of imaging modalities. COVID-19 is an emerging, rapidly evolving situation. 1997;96:2987 Y 91. PLoS One. Maron BJ, Doerer JJ, Haas TS, et al. Request PDF | Hypertrophic Cardiomyopathy in Athletes | Sudden cardiac death (SCD) in a young person is a rare but tragic occurrence. Sharma S, Elliott PM, Whyte G, et al. It may block or reduce the blood flow from the left ventricle to the aorta. Discrimination of the “athlete’s heart” from real disease by electrocardiogram and echocardiogram. In the literature up to 50% of cases of sudden cardiac death (SCD) in younger sportsmen were connected to hypertrophic cardiomyopathy. -, Exp Physiol. Background Hypertrophic cardiomyopathy is considered to be the most common cause of exercise-related sudden death in young athletes. 2. Impaired diastolic function, small LV cavity size, dynamic left ventricular outflow tract obstruction and microcirculatory coronary disease leading to a reduction in subendocardial flow can all cause failure to augment stroke volume during exercise and low peak oxygen consumption. Prevalence of Hypertrophic Cardiomyopathy in Highly Trained Athletes: Relevance to Pre-Participation Screening Sandeep Basavarajaiah, Matthew Wilson, Gregory Whyte, Ajay Shah, William McKenna, Sanjay Sharma Hypertrophic cardiomyopathy (HCM) is regarded to be the most common cause of sudden death in young athletes; however, the prevalence of HCM in elite athletes is unknown. The single most common cardiovascular cause of sudden death in young athletes in the United States, and the focal point of this article, is hypertrophic cardiomyopathy (HCM) , , , , , , accounting for about 35% of such events (Fig. Erickson CC. Hypertrophic cardiomyopathy and other causes of sudden cardiac death in young competitive athletes, with considerations for preparticipation screening and criteria for disqualification. Utility of metabolic exercise testing in distinguishing hypertrophic cardiomyopathy from physiologic left ventricular hypertrophy in athletes. The upper limits of physiologic cardiac hypertrophy in highly trained elite athletes. ST segment depression was observed in over half of athletes with HCM and one-quarter demonstrated pathological Q waves. Search text. Molecular Mechanisms Underlying Cardiac Adaptation to Exercise. All rights reserved. Kawasaki T, Azuma A, Kuribayashi T, et al. Many do not, however, reveal any phenotypic features of HCM and in such genotype positive/phenotype negative individuals, the exercise recommendations vary between the USA and Europe. Differentiating left ventricular hypertrophy in athletes from that in patients with hypertrophic cardiomyopathy. Published content on this site is for information purposes and is not a substitute for professional medical advice. Abnormal T wave inversion (TWI) is the hallmark of HCM and observed in over three-quarters of athletes with the condition according to a recent study.19 In another recent study TWI was more common among 106 athletes with HCM compared to 101 sedentary individuals with HCM (96 % versus 84 %, p=0.003)16 with the lateral leads most frequently involved. A diagnosis of HCM may be challenging in athletes as pathological hypertrophy of the left ventricle may also mimic physiological left ventricular hypertrophy (LVH) in response to exercise. 2017 May 2;25(5):1012-1026. doi: 10.1016/j.cmet.2017.04.025. Clipboard, Search History, and several other advanced features are temporarily unavailable. Maron BJ, Udelson JE, Bonow RO, et al. Hypertrophic cardiomyopathy is predominantly a disease of left ventricular outflow tract obstruction. 2000; Basavarajaiah S, Wilson M, Junagde S, et al. Would you like email updates of new search results? 2014 ESC Guidelines on diagnosis and management of hypertrophic cardiomyopathy: The Task Force for the Diagnosis and Management of Hypertrophic Cardiomyopathy of the European Society of Cardiology (ESC). Most patients with HCM have impaired diastolic filling of the left ventricle, and about 25% have left ventricular outflow tract obstruction. When comparing athletes with HCM to sedentary affected individuals, there is no discernible difference in the presence of myocardial fibrosis (33 % versus 40.6 %, p=0.258).16 Athletes with HCM, however, could have a lower ischaemic burden in the absence of mechanical LVOTO, severe LVH and microcirculatory disease. Incidence of sudden cardiac death in national collegiate athletic association athletes. Schnell F, Riding N, O’Hanlon R, et al. In brief Hypertrophic cardiomyopathy brief (HCM) accounts for a large proportion of sudden deaths in young athletes. Maron MS, Olivotto I, Zenovich AG, et al. Clin Res Cardiol. There are important differences regarding diastolic filling patterns. Studies have also revealed a strong male preponderance for SCD, particularly in African American athletes who compete in sports with sudden movements and adrenergic surges such as football or basketball.5 Unfortunately over 80 % of affected individuals are asymptomatic before SCD, which often occurs during exercise or in its aftermath. Vinereanu D, Florescu N, Sculthorpe N, et al. There is an overlap between this type of physiologic cardiac hypertrophy and mild forms of hypertrophic cardiomyopathy (HCM), the most common genetic disorder of the cardiovascular system with a prevalence of 0.2%. Introduction. eCollection 2016. Another study from the same group investigated 16 patients with HCM and 10 athletes with physiological LVH. Assessment of global longitudinal strain (GLS) has also been shown to be useful with a measurement of more (negative) than −10 % resulting in a sensitivity of 87 % and specificity of 95 % for the diagnosis of HCM in a sedentary patient.23 A GLS of more than −15% in an athlete is deemed pathological. 3 Studies from the United States have consistently found that hypertrophic cardiomyopathy was the most common cause of cardiac arrest in young competitive athletes (up to 30 percent). Objective Distinguishing early dilated cardiomyopathy (DCM) from physiological left ventricular (LV) dilatation with LV ejection fraction <55% in athletes (grey zone) is challenging. Harmon KG, Asif IM, Klossner D, Drezner JA. Recommendations for competitive sports participation in athletes with cardiovascular disease: a consensus document from the Study Group of Sports Cardiology of the Working Group of Cardiac Rehabilitation and Exercise Physiology and the Working Group of Mycardial and Pericardial Diseases of the European Society of Cardiology. In case of HCM diastolic dysfunction (mostly relaxation disturbances) occurs in the majority of patients and is therefore inconsistent with an athlete's heart. Sudden Cardiac Death (SCD) is the leading cause in death among young athletes (Montagnana, Lippi, Franchini, Banfi, & Guidi, 2008). Workup of an athlete with possible cardiomyopathy includes detailed history and physical, electrocardiogram (ECG), echocardiogram, and cardiac magnetic resonance imaging (MRI). Most athletes with HCM, however, demonstrate normal diastolic function according to conventional parameters.17 Using E prime 9 cm/s as a cut-off for pathology according to British Society of Echocardiogram guidelines22 revealed a sensitivity of only 35 % among 56 athletes, 37 of whom were diagnosed with HCM, with the remaining 19 athletes having physiological LVH. Oxborough D, Zaidi A, Gati S, et al. Search type Research Explorer Website Staff directory. Systolic function is normal in highly trained athletes and the majority of HCM patients as well. The sensitivity fell further to 14 % when using an E/E prime ratio >12 as a marker of pathology. A symmetrical increase in LV wall thickness in a homogenous pattern is seen in athletes with physiological LVH. Premium Drupal Theme by Adaptivethemes.com. ESC recommendations adopt a more conservative attitude on the grounds that a genetic predisposition may promote arrhythmogenesis even in the absence of LVH. Elliott PM, Anastasakis A, Borger MA, et al. Maron BJ, Gohman TE AD. We evaluated the role of a cascade of investigations to differentiate these two entities. Hypertrophic cardiomyopathy reduces the functional capacity of an affected person, leading to a physical inability to participate in high-intensity sports. A Guideline for the Practice of Echocardiography in the Cardiovascular Screening of Sports Participants: A Joint Policy Statement for the British Society of Echocardiography and Cardiac Risk in the Young. Coupled with the heterogeneous clinical course of the condition making such sequelae difficult to predict, any form of exercise prescription therefore errs on the side of caution. In obstructive HCM, the wall (septum) between the two bottom chambers of the heart thickens. Athletes with HCM exhibit less LVH than sedentary individuals with HCM (15.8 mm versus 19.7 mm, p<0.001) with a third demonstrating hypertrophy confined to the LV apex.16 The traditional ‘grey zone’ would only include 14 % of athletes with HCM who demonstrated mild concentric LVH that could also be interpreted as physiological LVH. Where views/opinions are expressed, they are those of the author(s) and not of Radcliffe Medical Media. Hypertrophic cardiomyopathy (HCM) is the most common cardiac genetic disorder. HCM is a cardiac condition characterized by an abnormal thickening of the heart muscle, a condition called hypertrophy. Two-dimensional strain analysis of the global and regional myocardial function for the differentiation of pathologic and physiologic left ventricular hypertrophy: a study in athletes and in patients with hypertrophic cardiomyopathy. 2009 Jul;98(7):465-6; author reply 467-8. doi: 10.1007/s00392-009-0035-z. In nonobstructive HCM, the heart’s main pumping chamber still becomes stiff. The overarching aim of managing athletes with HCM is to mitigate their risk of developing potential sequelae of the condition, including SCD. It … Please enable it to take advantage of the complete set of features! Physiologic limits of left ventricular hypertrophy in elite junior athletes: relevance to differential diagnosis of athlete’s heart and hypertrophic cardiomyopathy. Although hypertrophic cardiomyopathy (HCM) is a disease, which is known almost 60 years, change of opinions on the condition has occurred many times in history, and sometimes there has been 180-degree turn around. T1 mapping and extracellular volume (ECV) content measurement may help differentiate physiological LVH from mild HCM on CMR. Curr Hypertens Rep. 2015 Oct;17(10):77. doi: 10.1007/s11906-015-0588-3. Eckart RE, Scoville SL, Campbell CL, et al. -, Eur Heart J. 1 The clinical profile of athletes with HCM capable of competing in sporting activities at an extraordinarily high level has not been characterized. | Swoboda PP, McDiarmid AK, Erhayiem B, et al. USA.gov. In the vast majority of young athletes (less than 35 years of age) sudden death is due to underlying structural cardiovascular disease. It is therefore the most common cause of SCD in highly trained young athletes. D'Andrea A, Caso P, Cuomo S, Salerno G, Scarafile R, Mita C, De Corato G, Sarubbi B, Scherillo M, Calabrò R. Br J Sports Med. 2006 Aug;27(16):1933-41 Athletes with physiological LVH, particularly those participating in endurance sports, demonstrate the greatest LV cavity size causing enhanced diastolic filling and subsequent generation of large stroke volume. A correct diagnosis may on the one hand prevent some athletes from sudden cardiac death. In the United States, HCM is probably the leading cause of death among athletes with sudden cardiac death. Epub 2009 Jun 9. Hypertrophic Cardiomyopathy (HCM) is a rare but devastating diagnosis for an athlete. The highest sensitivity for identifying HCM in the athlete was found using longitudinal function as a discriminating marker (S prime <9 cm/s) albeit at 43 % with a specificity of 84 %. The most fundamental change concerned the prognosis of HCM. Vega RB, Konhilas JP, Kelly DP, Leinwand LA. These feat… Hypertrophic cardiomyopathy was detected in 22 athletes (0.07 percent) at preparticipation screening and accounted for 3.5 percent of the cardiovascular reasons for disqualification. The diagnosis of hypertrophic cardiomyopathy can be challenging in the athlete. 2013. NLM Several prominent athletes have been affected by the condition over the years. VO2 max variations are lacking for both African American athletes who are competing in increasing numbers at every level of sport internationally and also athletes with HCM. Cardiac adaptation to exercise in adolescent athletes of African ethnicity: an emergent elite athletic population. HCM is also associated with abnormal function of the mitral valve. However, data are emerging that report the clinical features of athletes with HCM. NIH It is not affiliated with or is an agent of, the Oxford Heart Centre, the John Radcliffe Hospital or the Oxford University Hospitals NHS Foundation Trust group. Intensive endurance training is able to cause a distinct pattern of functional and structural changes of the cardiovascular system. Hypertrophic Cardiomyopathy (HCM) causes disability and death in patients of all ages, with the most devastating component of its natural history being sudden death in youth: For example in American athletes under the age of 30, HCM is the first cause of sudden death (36% of total) (1). 2001 Dec;86(6):709-14 A recent study of 28 healthy athletes and 25 patients with HCM reported that a cut-off of 54 mm for LV cavity size had a sensitivity and specificity of 100% to help distinguish physiological LV hypertrophy from HCM.21 In athletes with HCM, however, 14 % of athletes with HCM revealed an LV cavity >54 mm with an upper limit of 60 mm.16. 2003 Sep;88(5):639-44 JAMA. The abbreviation is also pronounced “hocum”. Diastolic Dysfunction in Hypertrophic Cardiomyopathy. A study of 30 endurance athletes and 15 sedentary patients revealed that the ECV component of LV mass was similar between athletes and controls, yet athletes showed a significantly higher indexed cellular mass compared with controls.24 Furthermore, there was an inverse relationship between athletes demonstrating the highest functional capacity (peak oxygen consumption, VO2 max >60 mls/min per kg) and ECV on CMR using T1 mapping. In an unknown proportion of athletes a so called "athlete's heart" develops. HHS Effects of High-Intensity Training of Professional Runners on Myocardial Hypertrophy and Subclinical Atherosclerosis. Left ventricular remodeling and the athlete's heart, irrespective of quality load training. Left ventricular cavity enlargement is also observed in most athletes with physiological LVH, which is a response to an increased cardiac workload associated with exercise, as opposed to sedentary patients with HCM where the LV dilatation indicates end-stage disease and reduced functional capacity. Hypertrophic cardiomyopathy appears to be the most common cause of such deaths and may account for about one-half of the sudden deaths in a youthful athletic population. -, Heart. Key features in the distinction between athlete’s heart and hypertrophic cardiomyopathy are the appropri-ately increased size of the LV internal dimension in endurance athletes, and the normal systolic and par- Aneil Malhotra, Cardiology Clinical and Academic Group, St George’s, University of London, Cranmer Terrace, London SW17 0RE, UK. 1 But it is best known for its tragic outcomes—the sudden cardiac death (SCD) of young athletes, many of whom are in high school or college. Circulation. Jensen MK, Havndrup O, Christiansen M, et al. Hypertrophic cardiomyopathy was detected in 22 athletes (0.07 percent) at preparticipation screening and accounted for 3.5 percent of the cardiovascular reasons for disqualification. In contrast, physiological LVH results from an increase in myocyte size and relative reduction in the ECV. The multi-modality cardiac imaging approach to the Athlete's heart: an expert consensus of the European Association of Cardiovascular Imaging. Prog Cardiovasc Dis. The thickened heart muscle can make it harder for the heart to pump blood.Hypertrophic cardiomyopathy often goes undiagnosed because many people with the disease have few, if any, symptoms and can lead normal lives with no significant problems. Harmon KG, Asif IM, Klossner D DJ. If you do the math, there are around 14,000 people in the Dallas-Fort Worth area who potentially have an enlarged heart muscle – called hypertrophic cardiomyopathy (HCM) – a potentially deadly condition. Symptoms vary from none to feeling tired, leg swelling, and shortness of breath. Physiological hypertrophy is consistent with a normal diastolic function with even increased early diastolic filling. Pelliccia A, Maron BJ, Spataro A, et al. Sudden cardiac death (SCD) in a young person is a rare but tragic occurrence. Hypertrophic cardiomyopathy (HCM) is a heterogeneous condition with highly variable phenotypic expression and is the leading cause of sudden cardiac death in young athletes worldwide. Re: Athlete's heart or hypertrophic cardiomyopathy? The athlete's heart shows an eccentric biventricular hypertrophy with wall thicknesses under 15 mm and a moderately dilated left ventricle (LVEDD up to 58 mm). Athletes who perform regular and intensive exercise regimes develop a variety of electrical and structural cardiac adaptations that manifest functionally to improve stroke volume and performance. However, in a small number of people wi… Sharma S, Maron BJ, Whyte G, et al. Radcliffe Cardiology is part of Radcliffe Medical Media, an independent publisher and the Radcliffe Group Ltd. Cardiac MRI is the gold standard imaging tool for assessment of HCM in athletes and non-athletes. Penetrance of hypertrophic cardiomyopathy in children and adolescents: a 12-year follow-up study of clinical screening and predictive genetic testing. T1 measurements identify extracellular volume expansion in hypertrophic cardiomyopathy sarcomere mutation carriers with and without left ventricular hypertrophy. female athletes, but the upper physiological limit appears to be 15mm and 13mm, respectively. The author has no conflicts of interest to declare. Prevalence of sudden cardiac death during competitive sports activities in Minnesota high school athletes. Corrado D, Basso C, Schiavon M, Pelliccia A, Thiene G. Pre-participation screening of young competitive athletes for prevention of sudden cardiac death. One study of over 3,000 British elite athletes revealed an HCM prevalence of 1:1500 with only morphologically mild expressions of the disease.3 The Italian screening experience also reports a similar prevalence among over 33,000 young athletes. Athletes Are At Risk from Hypertrophic Cardiomyopathy. Pelliccia A, Maron BJ, Spataro A, et al. Myofibre disarray in HCM, coupled with impaired sarcoplasmic calcium kinetics leads to reduced myocardial relaxation and diastolic dysfunction. Content on this site is intended for healthcare professionals only, Tips For Increasing Article Visibility And Impact, European Cardiology Review 2017;12(2):80–2. LVOTO can be present during exercise in up to 70 % of patients with HCM.13. Differentiating between physiologically adaptive left ventricular (LV) hypertrophy observed in athletes' hearts and pathological HCM remains challenging. Hypertrophic cardiomyopathy (HCM) is a disease in which the heart muscle (myocardium) becomes abnormally thick (hypertrophied). Hypertrophic cardiomyopathy: a systematic review. Patients with HCM reveal high T1 signals and increased ECV due to inflammation and fibrosis in the extra-cellular space. This limits how much blood the ventricle can take in and pump out, but blood flow is not blocked. A morphologically mild phenotype of the condition may mimic physiological left ventricular hypertrophy and requires careful evaluation of the athlete with an array of clinical tools.

Eligibility and disqualification recommendations for competitive athletes with cardiovascular abnormalities: Task Force 3: Hypertrophic Cardiomyopathy, Arrhythmogenic Right Ventricular Cardiomyopathy and Other Cardiomyopathies, and Myocarditis: A Scientific Statement from the American Heart Association and American College of Cardiology. Differentiating physiological left ventricular hypertrophy from hypertrophic cardiomyopathy in athletes: proposed echocardiographic protocol. Both the American (AHA/ACC) and European (ESC) recommendations prohibit competitive sports with medium to high dynamic/static components.29,30 This encompasses many mainstream sports with competitive participation limited to low dynamic and low static sports such as bowling and golf. -, Br J Sports Med. Hypertrophic cardiomyopathy is traditionally viewed as the most common condition responsible for sudden cardiac death (SCD) in young athletes.2–4 In a large case series of SCD in 1,866 young athletes, HCM was the causative condition identified in nearly 40 % of cases.4 Nearly two-thirds of athletes were 17 years old or younger and still at high school. 16. Bittencourt CR, Izar MC, Schwerz VL, Póvoa RM, Fonseca HA, Fonseca MI, Bianco HT, França CN, Ferreira CE, Fonseca FA. 2015 Apr;16(4):353. doi: 10.1093/ehjci/jeu323. Athletes dying of Sudden Cardiac Death (Hypertrophic Cardiomyopathy or HCM) have sparked recent news and media attention with a growing push for athletes to receive heart screening. Usual testing does not detect HCM – many athletes have normal EKGs prior to having their fatal event.. Maron BJ, Udelson JE, Bonow RO, et al. In most reports, HCM is found at autopsy in as many as 40% of young athletes with sudden death. Assessment of left ventricular hypertrophy in a trained athlete: differential diagnosis of physiologic athlete's heart from pathologic hypertrophy. A VO2 max of >50 ml/kg per min, or >120 % of age-predicted value has traditionally been used to differentiate physiological LVH from HCM.26 However, there are certain limitations regarding the widespread applicability of this value given that the cut-off was based primarily on white male athletes. Assessing myocardial extracellular volume by T1 mapping to distinguish hypertrophic cardiomyopathy from athlete’s heart. The cessation of exercise for 6 to 8 weeks has been shown to reverse some of the structural and electrical changes associated with exercise, including normalization of TWI on the resting ECG and regression of physiological LVH.27 In contrast, an athlete with HCM will continue to demonstrate a pathological phenotype irrespective of whether they have undertaken a period of detraining or not.28, Management of Athletes with Hypertrophic Cardiomyopathy. An ECV >22.5% differentiated physiological LVH from HCM with a sensitivity of 100 % and specificity of 90 %.24. Sheikh N, Papadakis M, Carre F, et al. Maron BJ. Utility of metabolic exercise testing in distinguishing hypertrophic cardiomyopathy from physiologic left ventricular hypertrophy in athletes. Systolic anterior motion (SAM) of the mitral valve against the inter-ventricular septum causing dynamic LVOTO is present in approximately 25 % of sedentary HCM individuals and up to 70 % of cases during exercise.13 Athletes with HCM do not usually reveal baseline or dynamic LVOTO.
