Maron BJ. 2002;287:1308-1320. 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. Morphology of the “athlete’s heart” assessed by echocardiography in 947 elite athletes representing 27 sports. 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. We evaluated the role of a cascade of investigations to differentiate these two entities. Additionally, in a subgroup of 55 healthy athletes with physiological LVH, abnormal TWI, ST segment depression or pathological Q waves were absent in everyone. Cardiac adaptation to exercise in adolescent athletes of African ethnicity: an emergent elite athletic population. 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). 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. Aneil Malhotra, Cardiology Clinical and Academic Group, St George’s, University of London, Cranmer Terrace, London SW17 0RE, UK. Ho CY, Abbasi SA, Neilan TG, et al. Hypertrophic cardiomyopathy is characterised by asymmetric septal hypertrophy with a maximum LV wall thickness ≥15 mm in adults or >9 Z score (>2 Z score in adolescents and children).11 There is usually concomitant hyperdynamic systolic function, a relatively small LV cavity size and reduced diastolic function.12 Dynamic LV outflow tract obstruction (LVOTO) can be caused by systolic anterior motion of the mitral valve in up to one-third of patients. Alternatively, use our A–Z index  |  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. 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. 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. Effects of High-Intensity Training of Professional Runners on Myocardial Hypertrophy and Subclinical Atherosclerosis. 2006 Aug;27(16):1933-41 Myocardial fibrosis as an early manifestation of hypertrophic cardiomyopathy. 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. 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. This distinction is particularly important in a young person: a diagnosis of HCM has significant ramifications on participation in competitive sport, yet an erroneous diagnosis of physiological adaptation in a young athlete with HCM may subject them to an increased risk of SCD. A correct diagnosis may on the one hand prevent some athletes from sudden cardiac death. Myofibre disarray in HCM, coupled with impaired sarcoplasmic calcium kinetics leads to reduced myocardial relaxation and diastolic dysfunction. Penetrance of hypertrophic cardiomyopathy in children and adolescents: a 12-year follow-up study of clinical screening and predictive genetic testing. 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. Epub 2017 Jan 9. Differentiating physiological LVH from morphologically mild HCM in the athlete is particularly challenging with an array of clinical tools used to aid the clinician to make the correct diagnosis. Most studies are based on comparisons of clinical tests between healthy unaffected athletes and sedentary individuals with HCM. T1 mapping and extracellular volume (ECV) content measurement may help differentiate physiological LVH from mild HCM on CMR. The prevalence of HCM in elite athletes has never been reported but has important implications with regard to pre-participation screening for the disorder. 1 The clinical profile of athletes with HCM capable of competing in sporting activities at an extraordinarily high level has not been characterized. 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. Pelliccia A. Remodeling of left ventricular hypertrophy in elite athletes after long-term deconditioning. Sharma S, Elliott PM, Whyte G, et al. Another study from the same group investigated 16 patients with HCM and 10 athletes with physiological LVH. A small proportion (2 %) of athletes who are white, male and compete in endurance sports have been reported to demonstrate LVH between 13 and 15 mm, which can also mimic morphologically mild HCM.2,3 Further studies revealed that ethnicity affects the degree of LVH, with up to 18 % of African American adult athletes exhibiting an LV wall thickness of >12 mm but never beyond 16 mm.10 The ‘grey zone’ is therefore larger in African American athletes. 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. Epub 2014 Dec 24. 1997;96:2987 Y 91. 1, Fig. However, in a small number of people wi… Hypertrophic cardiomyopathy caused only 1 sudden death among the athletes (2.0 percent) but caused 16 sudden deaths in the nonathletes (7.3 percent). The abbreviation is also pronounced “hocum”. LVOTO can be present during exercise in up to 70 % of patients with HCM.13. Neither history nor physical examination are reliable to identify those at risk. Hypertrophic cardiomyopathy (HCM) is a condition in which a portion of the heart becomes thickened without an obvious cause. Hypertrophic cardiomyopathy: a systematic review. Swoboda PP, McDiarmid AK, Erhayiem B, et al. Apart from clinical examination and some non-specific ECG-changes, Echocardiography is the method of choice. Hypertrophic Cardiomyopathy and Athletes. Sudden cardiac death (SCD) in a young person is a rare but tragic occurrence. In most reports, HCM is found at autopsy in as many as 40% of young athletes with sudden death. The impact is widespread, particularly in the modern era of media coverage and visibility of social media. Hypertrophic cardiomyopathy is predominantly a disease of left ventricular outflow tract obstruction. 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. Athlete’s heart, hypertrophic cardiomyopathy, left ventricular hypertrophy, sudden cardiac death.

Discrimination of the “athlete’s heart” from real disease by electrocardiogram and echocardiogram. Would you like email updates of new search results? 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. NLM -, Br J Sports Med. 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%.

In contrast, physiological LVH results from an increase in myocyte size and relative reduction in the ECV. 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. 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). eCollection 2016. T1 measurements identify extracellular volume expansion in hypertrophic cardiomyopathy sarcomere mutation carriers with and without left ventricular hypertrophy. 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. Vagal enhancement due to subendocardial ischemia as a cause of abnormal blood pressure response in hypertrophic cardiomyopathy. 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). On the other hand sportsmen with an athlete's heart are reassured and able to continue as competitors. The author has no conflicts of interest to declare. 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. In the literature up to 50% of cases of sudden cardiac death (SCD) in younger sportsmen were connected to hypertrophic cardiomyopathy. In the vast majority of young athletes (less than 35 years of age) sudden death is due to underlying structural cardiovascular disease. 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.

The walls of the pumping chamber can also become stiff. 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. HCM is also associated with abnormal function of the mitral valve. 2006 Mar;40(3):244-50; discussion 244-50 Secchi F, Di Leo G, Petrini M, Spairani R, Alì M, Guazzi M, Sardanelli F. Radiol Med.

ST segment depression was observed in over half of athletes with HCM and one-quarter demonstrated pathological Q waves. Intensive endurance training is able to cause a distinct pattern of functional and structural changes of the cardiovascular system. 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. ESC recommendations adopt a more conservative attitude on the grounds that a genetic predisposition may promote arrhythmogenesis even in the absence of LVH. female athletes, but the upper physiological limit appears to be 15mm and 13mm, respectively. 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. Left Ventricular Dimensions in Athletes with HCM. Harmon KG, Asif IM, Klossner D, Drezner JA. 2013. An attenuation of or drop in blood pressure response during exercise is noted in nearly one-quarter of patients with HCM. Plausible mechanisms are abnormal vascular tone, small vessel ischaemia or exertional LVOTO.25 ECG markers of pathology may also be noted during exercise and include ST segment depression, TWI or ventricular arrhythmias. Differentiating between physiologically adaptive left ventricular (LV) hypertrophy observed in athletes' hearts and pathological HCM remains challenging. 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). Incidence of sudden cardiac death in national collegiate athletic association athletes. 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. The overarching aim of managing athletes with HCM is to mitigate their risk of developing potential sequelae of the condition, including SCD. Molecular Mechanisms Underlying Cardiac Adaptation to Exercise. Pelliccia A, Fagard R, Bjørnstad HH, et al. 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. Vega RB, Konhilas JP, Kelly DP, Leinwand LA. Pitfalls in the differentiation between athlete's heart and hypertrophic cardiomyopathy. Butz T, van Buuren F, Mellwig KP, et al. 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- 16. Sheikh N, Papadakis M, Carre F, et al. In fact, HCM can present at any time from infancy through old age, and has a broad range of manifestations. It may block or reduce the blood flow from the left ventricle to the aorta. 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. The multi-modality cardiac imaging approach to the Athlete's heart: an expert consensus of the European Association of Cardiovascular Imaging. Sudden Cardiac Death (SCD) is the leading cause in death among young athletes (Montagnana, Lippi, Franchini, Banfi, & Guidi, 2008). Hypertrophic cardiomyopathy (HCM) is reported historically as the most common cause of SCD in athletes younger than 35 years of age. Utility of metabolic exercise testing in distinguishing hypertrophic cardiomyopathy from physiologic left ventricular hypertrophy in athletes. This article focuses on studies that help shed further light to aid the clinical differentiation of physiological LVH from HCM. In the United States, HCM is probably the leading cause of death among athletes with sudden cardiac death. Physiologic limits of left ventricular hypertrophy in elite junior athletes: relevance to differential diagnosis of athlete’s heart and hypertrophic cardiomyopathy. Maron BJ, Udelson JE, Bonow RO, et al. In case of HCM diastolic dysfunction (mostly relaxation disturbances) occurs in the majority of patients and is therefore inconsistent with an athlete's heart. Spirito P, Pelliccia A, Proschan MA, et al. Conversely in HCM, irregular patterns of hypertrophy occur that are localised to the septum or apex in an asymmetrical manner. J Electrocardiol. JAMA. 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.

A symmetrical increase in LV wall thickness in a homogenous pattern is seen in athletes with physiological LVH. Influence of Physical Activity on Hypertension and Cardiac Structure and Function. NIH 2, Fig. Maron MS, Olivotto I, Zenovich AG, et al. HCM is caused by mutations in 14 genes coding for sarcomere proteins. 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 %. Curr Hypertens Rep. 2015 Oct;17(10):77. doi: 10.1007/s11906-015-0588-3. Maron BJ. 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. It is commonly reported that hypertrophic cardiomyopathy is the commonest case of exercise-related sudden cardiac death. 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. Cardiac MRI is the gold standard imaging tool for assessment of HCM in athletes and non-athletes. USA.gov. 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. Hypertrophic cardiomyopathy and other causes of sudden cardiac death in young competitive athletes, with considerations for preparticipation screening and criteria for disqualification. Oxborough D, Zaidi A, Gati S, et al. Assessing myocardial extracellular volume by T1 mapping to distinguish hypertrophic cardiomyopathy from athlete’s heart. 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. In up to 70% of cases left ventricular outflow tract obstruction is evident during stress echocardiography. Kawasaki T, Azuma A, Kuribayashi T, et al. 1981 Apr;63(4):882-94 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. The diagnosis of hypertrophic cardiomyopathy can be challenging in the athlete. 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. Prognostic value of intra-left ventricular electromechanical asynchrony in patients with mild hypertrophic cardiomyopathy compared with power athletes. The upper limits of physiologic cardiac hypertrophy in highly trained elite athletes. 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. The most fundamental change concerned the prognosis of HCM. Clin Res Cardiol. The sensitivity fell further to 14 % when using an E/E prime ratio >12 as a marker of pathology. 2016 Nov 17;14(1):46. doi: 10.1186/s12947-016-0088-x. Malhotra A, Sheikh N, Dhutia H, et al. Differentiating left ventricular hypertrophy in athletes from that in patients with hypertrophic cardiomyopathy. Physiological hypertrophy is consistent with a normal diastolic function with even increased early diastolic filling. 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. Hypertrophic cardiomyopathy (HCM) remains the commonest cause of sudden cardiac death among young athletes. 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. 2003 Sep;88(5):639-44 Hypertrophic cardiomyopathy (HCM) is the most common cardiac genetic disorder. Maron B. 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. 2015 May-Jun;48(3):373-9. doi: 10.1016/j.jelectrocard.2014.12.016.
