hypertrophic cardiomyopathy athletes

OBJECTIVES: Hypertrophic cardiomyopathy (HCM) is a life-threatening genetic cardiovascular disease that often goes undetected in young athletes. Structural features of the athlete heart as defined by echocardiography. Pelliccia A. Remodeling of left ventricular hypertrophy in elite athletes after long-term deconditioning. Curr Hypertens Rep. 2015 Oct;17(10):77. doi: 10.1007/s11906-015-0588-3. Secchi F, Di Leo G, Petrini M, Spairani R, Alì M, Guazzi M, Sardanelli F. Radiol Med. 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. USA.gov. This results in the heart being less able to pump blood effectively. 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. 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. US data suggest an incidence ranging from anywhere between 0.5 and 13 per 100,0006,7 yet current methods of data collection have also been highlighted as underestimating the true incidence of SCD.8, Most studies have focused on HCM in sedentary individuals while few have focused on athletes. 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. Clinical profile of athletes with hypertrophic cardiomyopathy. 2017 May 2;25(5):1012-1026. doi: 10.1016/j.cmet.2017.04.025. ESC recommendations adopt a more conservative attitude on the grounds that a genetic predisposition may promote arrhythmogenesis even in the absence of LVH. 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. HCM is a complex disease with a broad clinical and morphologic spectrum. Objective Distinguishing early dilated cardiomyopathy (DCM) from physiological left ventricular (LV) dilatation with LV ejection fraction <55% in athletes (grey zone) is challenging. Hypertrophic cardiomyopathy: a systematic review. This site needs JavaScript to work properly. Sheikh N, Papadakis M, Schnell F, et al. 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. Influence of Physical Activity on Hypertension and Cardiac Structure and Function. HCM is a cardiac condition characterized by an abnormal thickening of the heart muscle, a condition called hypertrophy. 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%. Morphology of the “athlete’s heart” assessed by echocardiography in 947 elite athletes representing 27 sports. -, Br J Sports Med. Pitfalls in the differentiation between athlete's heart and hypertrophic cardiomyopathy. 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. In up to 70% of cases left ventricular outflow tract obstruction is evident during stress echocardiography. 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). However, data are emerging that report the clinical features of athletes with HCM. In brief Hypertrophic cardiomyopathy brief (HCM) accounts for a large proportion of sudden deaths in young athletes. 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. Maron B. The prevalence of HCM in elite athletes has never been reported but has important implications with regard to pre-participation screening for the disorder. HCM is commonly characterized by asymmetric left ventricular hypertrophy with a reduced LV-diameter. 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. doi: 10.1371/journal.pone.0166009. 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. Assessment of left ventricular hypertrophy in a trained athlete: differential diagnosis of physiologic athlete's heart from pathologic hypertrophy. NIH 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. Please enable it to take advantage of the complete set of features! Prognostic value of intra-left ventricular electromechanical asynchrony in patients with mild hypertrophic cardiomyopathy compared with power athletes. An ECV >22.5% differentiated physiological LVH from HCM with a sensitivity of 100 % and specificity of 90 %.24. Systolic function is normal in highly trained athletes and the majority of HCM patients as well. Sharma S, Maron BJ, Whyte G, et al. Prog Cardiovasc Dis. Usual testing does not detect HCM – many athletes have normal EKGs prior to having their fatal event.. A correct diagnosis may on the one hand prevent some athletes from sudden cardiac death. Maron BJ. Most studies are based on comparisons of clinical tests between healthy unaffected athletes and sedentary individuals with HCM. 2006 Mar;40(3):244-50; discussion 244-50 2017 Apr;122(4):265-272. doi: 10.1007/s11547-016-0718-2. Hypertrophic cardiomyopathy caused only 1 sudden death among the athletes (2.0 percent) but caused 16 sudden deaths in the nonathletes (7.3 percent). T1 mapping and extracellular volume (ECV) content measurement may help differentiate physiological LVH from mild HCM on CMR. The incidence of SCD in young athletes (<35 years of age) varies widely according to the population studied. 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. Hypertrophic cardiomyopathy (HCM) remains the commonest cause of sudden cardiac death among young athletes. Prevalence of hypertrophic cardiomyopathy in highly trained athletes: relevance to pre-participation screening. Hypertrophic cardiomyopathy is predominantly a disease of left ventricular outflow tract obstruction. 1, Fig. Maron BJ, Udelson JE, Bonow RO, et al. In the United States, HCM is probably the leading cause of death among athletes with sudden cardiac death. 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.

Spirito P, Pelliccia A, Proschan MA, et al. Sudden death in young adults: a 25-year review of autopsies in military recruits. 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. The author has no conflicts of interest to declare. Most patients with HCM have impaired diastolic filling of the left ventricle, and about 25% have left ventricular outflow tract obstruction. Patients with HCM reveal high T1 signals and increased ECV due to inflammation and fibrosis in the extra-cellular space. HHS Maron BJ, Gohman TE AD.

The sensitivity fell further to 14 % when using an E/E prime ratio >12 as a marker of pathology. Introduction. 2016 Nov 11;11(11):e0166009. 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.

Incidence of sudden cardiac death in national collegiate athletic association athletes. 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. Commonly referred to as an “enlarged heart” a Hypertrophic Cardiomyopathy (HCM) is a very real danger to athletes. Schnell F, Riding N, O’Hanlon R, et al. Harmon KG, Asif IM, Klossner D, Drezner JA. 2002;287:1308-1320. In most reports, HCM is found at autopsy in as many as 40% of young athletes with sudden death. The diagnosis of hypertrophic cardiomyopathy can be challenging in the athlete. Physiologic limits of left ventricular hypertrophy in elite junior athletes: relevance to differential diagnosis of athlete’s heart and hypertrophic cardiomyopathy. Most people with HCM have this type. Aneil Malhotra, Cardiology Clinical and Academic Group, St George’s, University of London, Cranmer Terrace, London SW17 0RE, UK.  |  -, Heart. 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. Cardiac MRI is the gold standard imaging tool for assessment of HCM in athletes and non-athletes. Symptoms vary from none to feeling tired, leg swelling, and shortness of breath. Where views/opinions are expressed, they are those of the author(s) and not of Radcliffe Medical Media. Maron MS, Olivotto I, Zenovich AG, et al. 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. PLoS One. Apart from clinical examination and some non-specific ECG-changes, Echocardiography is the method of choice. A symmetrical increase in LV wall thickness in a homogenous pattern is seen in athletes with physiological LVH. Harmon KG, Asif IM, Klossner D DJ. In nonobstructive HCM, the heart’s main pumping chamber still becomes stiff. Maron BJ. Ho CY, Abbasi SA, Neilan TG, et al. 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). 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. 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. Utility of metabolic exercise testing in distinguishing hypertrophic cardiomyopathy from physiologic left ventricular hypertrophy in athletes. This limits how much blood the ventricle can take in and pump out, but blood flow is not blocked. 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. Clin Res Cardiol. Swoboda PP, McDiarmid AK, Erhayiem B, et al. Rather than relying on conventional methods to differentiate physiological LVH from HCM,14,15 recent studies have focused on direct comparisons between athletes with HCM and those with physiological LVH16,17 to provide a better understanding of the clinical features of HCM in an athlete (Figure 1). New insights into electrophysiological changes during physiological hypertrophy could probably change this view. HCM is caused by mutations in 14 genes coding for sarcomere proteins.

Pelliccia A, Maron BJ, Spataro A, et al. In an unknown proportion of athletes a so called "athlete's heart" develops. Several prominent athletes have been affected by the condition over the years. The upper limit of physiologic cardiac hypertrophy in highly trained elite athletes. Intensive endurance training is able to cause a distinct pattern of functional and structural changes of the cardiovascular system. 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. 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. The multi-modality cardiac imaging approach to the Athlete's heart: an expert consensus of the European Association of Cardiovascular Imaging. 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. In the literature up to 50% of cases of sudden cardiac death (SCD) in younger sportsmen were connected to hypertrophic cardiomyopathy. 1997;96:2987 Y 91. Request PDF | Hypertrophic Cardiomyopathy in Athletes | Sudden cardiac death (SCD) in a young person is a rare but tragic occurrence. 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.

On the other hand sportsmen with an athlete's heart are reassured and able to continue as competitors. 2003 Sep;88(5):639-44 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. Oxborough D, Zaidi A, Gati S, et al. Vinereanu D, Florescu N, Sculthorpe N, et al. 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. Differentiation between physiologic and pathologic adaptations—electrical and structural—can be particularly challenging in endurance athletes and black athletes. Another study from the same group investigated 16 patients with HCM and 10 athletes with physiological LVH.

J Electrocardiol. Differentiation of physiological LVH from HCM requires an array of clinical tools that rely on detecting subtle features of disease in a supposedly healthy person who represents the segment of society with the highest functional capacity. 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. In obstructive HCM, the wall (septum) between the two bottom chambers of the heart thickens. Clin Res Cardiol.

An attenuation of or drop in blood pressure response during exercise is noted in nearly one-quarter of patients with HCM. . 2. Sudden cardiac death (SCD) in a young person is a rare but tragic occurrence. Hypertrophic cardiomyopathy (HCM) is reported historically as the most common cause of SCD in athletes younger than 35 years of age. 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. Assessing myocardial extracellular volume by T1 mapping to distinguish hypertrophic cardiomyopathy from athlete’s heart. 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). Hypertrophic Cardiomyopathy and Athletes. Ho CY, López B, Coelho-Filho OR, et al. Malhotra A, Sheikh N, Dhutia H, et al. The hypertrophy can cause several problems. 1. Physiological left ventricular hypertrophy or hypertrophic cardiomyopathy in an elite adolescent athlete: role of detraining in resolving the clinical dilemma. Physiological hypertrophy is consistent with a normal diastolic function with even increased early diastolic filling. Conversely in HCM, irregular patterns of hypertrophy occur that are localised to the septum or apex in an asymmetrical manner. 2000; Basavarajaiah S, Wilson M, Junagde S, et al. Effects of High-Intensity Training of Professional Runners on Myocardial Hypertrophy and Subclinical Atherosclerosis. Up to one-fifth of young athletes (aged between 14–35 years) reveal greater left ventricular (LV) wall thickness compared to sedentary controls, though the majority fall under 12 mm.1,2 A small proportion of athletes, however, reveal an LV wall thickness of 13–16 mm, which overlaps with morphologically mild hypertrophic cardiomyopathy (HCM). Prospective prognostic assessment of blood pressure response during exercise in patients with hypertrophic cardiomyopathy. Maron BJ, Udelson JE, Bonow RO, et al. Hypertrophic cardiomyopathy (HCM) is the most common cardiac genetic disorder. Because of this data a great interest in distinguishing these two diagnoses exists. Background Hypertrophic cardiomyopathy is considered to be the most common cause of exercise-related sudden death in young athletes. -, Exp Physiol. Workup of an athlete with possible cardiomyopathy includes detailed history and physical, electrocardiogram (ECG), echocardiogram, and cardiac magnetic resonance imaging (MRI). Differentiating physiological left ventricular hypertrophy from hypertrophic cardiomyopathy in athletes: proposed echocardiographic protocol. 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.

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. HCM is a huge deal in the sports world for one major reason; it can kill you. Diastolic function, ECG changes and family history have a significant impact. We evaluated the role of a cascade of investigations to differentiate these two entities. 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. Cardiac adaptation to exercise in adolescent athletes of African ethnicity: an emergent elite athletic population. Prevalence of sudden cardiac death during competitive sports activities in Minnesota high school athletes. 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. 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.
