Abstract
The changes of the athlete's heart are not well defined and characterized in children. We aimed to describe the morphological changes of the heart related to sport in young athletes. We evaluated a group of 331 young athletes under 18 years (mean 11.9 ± 3.2) who practice tennis: 58 (16.52%), football: 118 (33.62%), basketball: 16 (4.56%), athletics: 40 (11.4%), and swimming: 99 (28.21%). Type of sport, years of practice, and duration of the training were collected. All children underwent echocardiography with the following M-mode parameters: left atrium diameter (LAD), interventricular septum (IVS), and left ventricle posterior Wall (LVPW), diastolic diameter of the left ventricle (LVDD), and right ventricle outflow tract (RVOT). The major finding of our study was that 20% of the children had a Z score > 2 for the IVS and that increased to 30% for the children playing tennis or swimming. Also, other changes like LA and RVOT dilatation were observed in about 10 and 14% of the cases, respectively. Taken together, these figures indicate that cardiac remodeling is frequent in children. Further studies are needed to establish consensus-based criteria of athlete's heart in young children.

[PMID: 33540539 PMCID: PMC7867204 DOI: 10.3390/ijms22031464] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2021] [Revised: 01/21/2021] [Accepted: 01/27/2021] [Indexed: 02/07/2023] Open
Abstract
Significant variations from the normal QT interval range of 350 to 450 milliseconds (ms) in men and 360 to 460 ms in women increase the risk for ventricular arrhythmias. This difference in the QT interval between men and women has led to the understanding of the influence of sex hormones on the role of gender-specific channelopathies and development of ventricular arrhythmias. The QT interval, which represents the duration of ventricular repolarization of the heart, can be affected by androgen levels, resulting in a sex-specific predilection for acquired and inherited channelopathies such as acquired long QT syndrome in women and Brugada syndrome and early repolarization syndrome in men. Manipulation of the homeostasis of these sex hormones as either hormonal therapy for certain cancers, recreational therapy or family planning and in transgender treatment has also been shown to affect QT interval duration and increase the risk for ventricular arrhythmias. In this review, we highlight the effects of endogenous and exogenous sex hormones in the physiological and pathological states on QTc variation and predisposition to gender-specific pro-arrhythmias.

Effect of age and gender on the QTc-interval in healthy individuals and patients with long-QT syndrome. Trends Cardiovasc Med 2017; 28:64-75. [PMID: 28869094 DOI: 10.1016/j.tcm.2017.07.012] [Citation(s) in RCA: 48] [Impact Index Per Article: 6.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2017] [Revised: 07/26/2017] [Accepted: 07/27/2017] [Indexed: 12/15/2022]
Abstract
Age- and gender-related differences in QTc-interval are most likely the result of changes in sex-specific hormones. Although the exact mechanisms and pathophysiology of sex hormones on the QTc-interval are not known, testosterone appears to shorten the QTc-interval. In females, however, there is a more complex interaction between progesterone and estrogen. In patients with an impaired repolarization, such as long-QT syndrome (LQTS), the effect of these sex hormones on the QTc-interval is more pronounced with a differing sensitivity between the LQTS genotypes.

Impact of specific training and competition on myocardial structure and function in different age ranges of male handball players. PLoS One 2015; 10:e0143609. [PMID: 26630561 PMCID: PMC4668105 DOI: 10.1371/journal.pone.0143609] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2015] [Accepted: 11/06/2015] [Indexed: 11/23/2022] Open
Abstract
Handball activity involves cardiac changes and demands a mixture of both eccentric and concentric remodeling within the heart. This study seeks to explore heart performance and cardiac remodeling likely to define cardiac parameters which influence specific performance in male handball players across different age ranges. Forty three players, with a regular training and competitive background in handball separated into three groups aged on average 11.78±0.41 for youth players aka “schools”, “elite juniors” 15.99±0.81 and “elite adults” 24.46±2.63 years, underwent echocardiography and ECG examinations. Incremental ergocycle and specific field (SFT) tests have also been conducted. With age and regular training and competition, myocardial remodeling in different age ranges exhibit significant differences in dilatation’s parameters between “schools” and “juniors” players, such as the end-diastolic diameter (LVEDD) and the end-systolic diameter of the left ventricle (LVESD), the root of aorta (Ao) and left atrial (LA), while significant increase is observed between “juniors” and “adults” players in the interventricular septum (IVS), the posterior wall thicknesses (PWT) and LV mass index. ECG changes are also noted but NS differences were observed in studied parameters. For incremental maximal test, players demonstrate a significant increase in duration and total work between “schools” and “juniors” and, in total work only, between “juniors” and “seniors”. The SFT shows improvement in performance which ranged between 26.17±1.83 sec to 31.23±2.34 sec respectively from “seniors” to “schools”. The cross-sectional approach used to compare groups with prior hypothesis that there would be differences in exercise performance and cardiac parameters depending on duration of prior handball practice, leads to point out the early cardiac remodeling within the heart as adaptive change. Prevalence of cardiac chamber dilation with less hypertrophy remodeling was found from “schools” to “juniors” while a prevalence of cardiac hypertrophy with less pronounced chamber dilation remodeling was noted later.

Abstract
Ensuring the safety of young athletes is a priority among health care providers. Controversy remains as to the best method of preparticipation screening. The American Academy of Pediatrics and the American Heart Association currently recommend screening with history and physical examination, without routine electrocardiogram or echocardiography. Meticulous conduction of a cardiac focused history and exam during the preparticipation evaluation can help identify those who may be at risk for sudden cardiac arrest. Understanding presenting signs of the most common cardiac diseases is useful in recognizing those in need of a directed cardiac evaluation before sports participation.
