Adaptation To Exercise

‘Athlete’s heart’ is associated with several structural and electrophysiological adaptations, which are reflected on the 12-lead electrocardiogram (ECG) and imaging studies. Most studies investigating cardiac remodelling in athletes are based on cohorts of white, adult, male athletes competing in the most popular sports. Evidence suggests, however, that sporting discipline and the athlete’s gender and ethnicity are important determinants of cardiovascular adaptation to exercise. Athletes competing in endurance sports demonstrate more pronounced adaptations in comparison to athletes performing static or resistance training. The ECG of endurance athletes is more likely to demonstrate repolarization anomalies in the anterior leads and ventricular dilatation on imaging studies, causing considerable overlap with arrhythmogenic right ventricular cardiomyopathy and dilated cardiomyopathy. Female athletes exhibit less pronounced adaptations compared to males, in terms of the prevalence of ECG changes and absolute cardiac dimensions. Importantly, female endurance athletes are more likely to demonstrate eccentric hypertrophy compared to males, suggesting that concentric remodelling or hypertrophy in female endurance athletes is unlikely to be the consequence of physiological adaptation to training. The most pronounced paradigm of ethnically distinct cardiovascular adaptation to exercise stems from black athletes, who exhibit a significantly higher prevalence of repolarization anomalies and left ventricular hypertrophy compared to white athletes, making the differentiation between athlete’s heart and hypertrophic cardiomyopathy challenging in this ethnic group.

Athlete's Heart

Athlete’s heart is a physiological adaptation to regular exercise. It is characterized by harmonic, eccentric dilatation of all cardiac chambers, typically seen in endurance athletes and athletes who engage in disciplines with high volumes of endurance exercise. In contrast to eccentric hypertrophy of the heart in endurance athletes, which has been demonstrated in echocardiographic and cardiovascular magnetic resonance (CMR) studies, the early hypothesis of concentric hypertrophy in strength athletes has not been confirmed by most of the newer echocardiographic and CMR studies. Because CMR offers high sensitivity and specificity to differentiate between physiological and pathological cardiac adaptations, CMR has become an important tool to examine athlete’s heart and to evaluate athletes’ sports eligibility. Therefore, modern CMR plays an important role in the scientific and clinical assessment of exercise-induced cardiac adaptations and the prevention of sudden cardiac death in athletes.

Introduction: Elite endurance athletes often develop left ventricular dilatation comparable to that observed in aortic regurgitation (AR). Hypothesis: We hypothesized that the LV remodeling observed in athlete’s heart differs from that seen in AR, and that the difference may be attributed to different fiber stress distribution. Methods: Thirty asymptomatic patients with moderate to severe AR, 15 age matched elite endurance athletes (Athl) and 17 age matched healthy controls (C) where analyzed with 3D speckle tracking echocardiography. We calculated the ratio between peak systolic circumferential (CS) - and peak systolic longitudinal strain (LS) and end-systolic (ES) circumferential (ESSc) and meridional (ESSm) fiber stress. Results: LV ejection fraction in C, Athl and AR patients was (61 ± 2, 61 ± 3 and 62 ± 3%, respectively, p=NS). LV end-diastolic volume was 78 ± 11, 112 ± 13 and 117 ± 20 ml/m 2 in C, Athl and AR, respectively, (C vs AR and Athl, p<0.01, AR vs Athl, p=NS). A non-uniform contraction pattern with a rightward shift of the LS strain curve was observed in AR (Figure 1). The CS/LS ratio was 0.91 ± 0.11, 0.91 ± 0.16 and 1.12 ± 0.24 in C, Athl and AR, respectively, (AR vs C and Athl, p<0.01, C vs Athl, p=NS). Consistently, the ESSc/ESSm ratio was similar in C and Athl (1.75 ± 0.08 and 1.74 ± 0.07, respectively, p=NS) and lower in AR patients (1.67 ± 0.07, AR vs C and Athl, p<0.01), indicating a relative increase in meridional fiber stress in the AR group (Figure 2). Conclusions: We have demonstrated that LV remodeling in AR patients differs from athlete’s heart with similar LV volumes, and may be attributed to a shift in the circumferential-meridional fiber stress ratio in AR patients.

AbstractTo provide clinically relevant criteria for differentiation between the athlete’s heart and similar appearing hypertrophic (HCM), dilated (DCM), and arrhythmogenic right-ventricular cardiomyopathy (ARVC) in MRI. 40 top-level athletes were prospectively examined with cardiac MR (CMR) in two university centres and compared to retrospectively recruited patients diagnosed with HCM (n = 14), ARVC (n = 18), and DCM (n = 48). Analysed MR imaging parameters in the whole study cohort included morphology, functional parameters and late gadolinium enhancement (LGE). Mean left-ventricular enddiastolic volume index (LVEDVI) was high in athletes (105 ml/m2) but significantly lower compared to DCM (132 ml/m2; p = 0.001). Mean LV ejection fraction (EF) was 61% in athletes, below normal in 7 (18%) athletes vs. EF 29% in DCM, below normal in 46 (96%) patients (p < 0.0001). Mean RV-EF was 54% in athletes vs. 60% in HCM, 46% in ARVC, and 41% in DCM (p < 0.0001). Mean interventricular myocardial thickness was 10 mm in athletes vs. 12 mm in HCM (p = 0.0005), 9 mm in ARVC, and 9 mm in DCM. LGE was present in 1 (5%) athlete, 8 (57%) HCM, 10 (56%) ARVC, and 21 (44%) DCM patients (p < 0.0001). Healthy athletes’ hearts are characterized by both hypertrophy and dilation, low EF of both ventricles at rest, and increased interventricular septal thickness with a low prevalence of LGE. Differentiation of athlete’s heart from other non-ischemic cardiomyopathies in MRI can be challenging due to a significant overlap of characteristics also seen in HCM, ARVC, and DCM.

Background: Asian representation in sport is increasing, yet there remains a lack of reference values for the Asian athlete's heart. Consequently, current guidelines for cardiovascular screening recommend using Caucasian athletes' norms to evaluate Asian athletes. This study aims to outline electrocardiographic and echocardiographic characteristics of the Asian athlete's heart using a Singaporean prospective registry of Southeast (SE) Asian athletes.Methods and Results: One hundred and fifty elite athletes, mean age of 26.1 ± 5.7 years (50% males, 88% Chinese), were evaluated using a questionnaire, 12-lead electrocardiogram (ECG) and transthoracic echocardiogram. All ECGs were analyzed using the 2017 International Recommendations. Echocardiographic data were presented by gender and sporting discipline. The prevalence of abnormal ECGs among SE Asian athletes was 6.7%—higher than reported figures for Caucasian athletes. The abnormal ECGs comprised mainly anterior T wave inversions (ATWI) beyond lead V2, predominantly in female athletes from mixed/endurance sport (9.3% prevalence amongst females). None had echocardiographic structural abnormalities. Male athletes had reduced global longitudinal strain compared to females (−18.7 ± 1.6 vs. −20.7 ± 2.1%, p &lt; 0.001). Overall, SE Asian athletes had smaller left ventricular cavity sizes and wall thickness compared to non-Asian athletes.Conclusion: SE Asian athletes have higher abnormal ECG rates compared to Caucasian athletes, and also demonstrate structural differences that should be accounted for when interpreting their echocardiograms compared to athletes of other ethnicities.

Athlete's Heart

Bradycardia, cardiomegaly, heart murmurs, and ECG changes are typically observed in adult endurance athletes, but frequency of such changes among children involved in sports training is unclear. Pediatricians need to be aware of whether these features of the " athlete's heart" occur in their patients, because such features may mimic those of cardiac disease. Fourteen prepubertal competitive male swimmers were evaluated by physical examination, ECG and echocardiogram, and findings were compared to those of a group of active but nontrained control boys. Lower resting heart rates and echocardiographic manifestations of chronic left ventricular volume overload were observed among the swimmers. These changes were not manifest on physical examination, however, and no significant ECG alterations were identified among the athletes. These findings indicate that, although features of the athlete's heart are present in children involved in endurance training, seldom will these findings simulate heart disease or be apparent on routine clinical examination.

Background Adult athletes undergo cardiac adaptions in what is known as the “athlete’s heart”. Cardiac adaptations in young athletes have not been described in longitudinal studies but have previously been believed to be uniform in nature. Methods Seventy-six cross-country skiers were assessed at age 12. Forty-eight (63%) completed the first follow-up at age 15 and 36 (47%) the second follow-up at age 18. Comprehensive exercise data were collected. Echocardiography with three-dimensional measurements and cardiopulmonary exercise testing were performed at all time points. The cohort was divided into active and former endurance athletes, with an eight hours of weekly endurance exercise cut-off at age 18. Results The athletes underwent eccentric remodelling between ages 12 and 15, and concentric remodelling between ages 15 and 18. At age 18, the active endurance athletes had greater increases in inter-ventricular wall thickness (1.8 ± 1.4 Δmm vs 0.6 ± 1.0 Δmm, p < 0.05), left ventricular (LV) posterior wall thickness (1.6 ± 1.2 Δmm vs 0.8 ± 0.8 Δmm, p < 0.05), LV mass (63 ± 30 Δg vs 27 ± 21 Δg, p < 0.01), right ventricular (RV) end-diastolic area (3.4 ± 4.0 Δcm2 vs 0.6 ± 3.5Δ cm2, p < 0.05), RV end-systolic area (1.0 ± 2.3 Δcm2 vs –0.9 ± 2.0 Δcm2, p < 0.05) and left atrial volume (24 ± 21 ΔmL vs 6±10 ΔmL, p < 0.05) and had greater indexed maximal oxygen uptake (66.3 ± 7.4 mL/min/kg vs 57.1 ± 8.2 mL/min/kg, p < 0.01). There was no significant difference for LV volumes. Conclusion This study finds a shift in the development of the young athlete’s heart. Between ages 12 and 15, the active endurance athletes underwent eccentric remodelling. This dynamic switched to concentric remodelling between ages 15 and 18.

Athlete's Heart

Long-term athletic conditioning is responsible for morphological cardiac changes that are collectively described as the ‘athlete’s heart’. Morphological changes are usually mild, but in a not trivial proportion of athletes may be more marked, by mimicking changes usually observed in certain cardiomyopathies, raising the question of differential diagnosis between physiological remodelling and structural cardiac diseases. In this chapter, the morphological features of the physiological left and right ventricular remodelling are described in comparison with the mimicking changes occurring, respectively, in hypertrophic cardiomyopathy, dilated cardiomyopathy, left ventricular non-compaction, and arrhythmogenic right ventricular cardiomyopathy. Differential diagnosis using imaging techniques (i.e. echocardiography and cardiac magnetic resonance) is discussed, and the most efficient and clinically useful criteria for diagnosis in each of the pathological conditions considered are provided.

Abstract Funding Acknowledgements Type of funding sources: Public grant(s) – National budget only. Main funding source(s): Ph.D fellowship of the Research Foundation Flanders (FWO). The Master@Heart trial is funded by the FWO. Introduction Differentiating intensive training induced hypertrophy from hyperthropic cardiomyopathy (HCM) is important to identify those young athletes at risk of sudden cardiac death. Swoboda and colleagues demonstrated that T1 and ECV mapping can aid such a differentiation between athletic and pathological hypertrophy, particularly in subjects with indeterminate wall thickness (1). Recently texture analysis (TA) methods of CMR data have demonstrated improved diagnostic accuracy over conventional qualitative analysis in various heart diseases. Only few studies have applied TA to T1 and ECV mapping data (2-4). Here we aimed to demonstrate that a TA approach provides superior capacity to distinguish HCM from athlete’s heart over average native T1 and ECV values. Purpose It was our hypothesis that a texture analysis of T1 and ECV mapping images would identify features that could discriminate between a HCM and athlete’s heart with a higher classification accuracy (CA) than average T1 and ECV values. Methods This study included data from 97 subjects diagnosed with HCM (acc. to guidelines; 5) and 28 athletes that took part in the Master@Heart trial (an ongoing study assessing the beneficial effects of long-term endurance exercise for the prevention of coronary artery disease, 6).  Long and short axis T1 mapping data was acquired on a 1.5T Philips Ingenia system using MOLLI (seconds scheme). After offline motion correction and T1 and ECV map calculation (7), the left ventricular myocardium was manually delineated (3D Slicer; 8). Texture analysis of the masked images resulted in 194 features (Pyradiomics, standard settings; 9). The dataset was then split (75/25%) for training and testing purposes keeping images from the same subject within the same set. A fast correlation based filter rank was applied to the training data to derive relevant features. A further reduction to only two features was based on the CA of a support vector machine (SVM) learning method (linear kernel; cost 0.9 regression loss epsilon 0.1; leave-one-out). Finally, ROC analysis on the test data was used to determine the diagnostic accuracy for the following predictors: (1) median T1 and ECV (2) two most relevant features (training) (3) combination of (1) and (2) (ROC AUC statistics (10)). Results The two most relevant features were the histogram feature ECV energy and the gray level size zone matrix (GLSZM) feature native T1 zone entropy, a measure of heterogeneity in the texture pattern. A model to distinguish HCM from athletes based on these features outperformed the model using only median T1 and ECV values with both higher sensitivity and specificity (table 1) and a significantly  higher AUC in the ROC analysis (p &lt; 0.05, figure 1). Combining these two features with median values did not improve the CA further.  Conclusion Texture analysis of motion-corrected T1 and ECV mapping images out-performs classical analysis based on average values in distinguishing HCM from athlete"s heart.
