“…Because most of the studies addressing phenotypic expression and natural history of HCM are based on white patients, data on individuals of other ethnicities are limited. However, observations in athletes and patients with hypertension reveal that individuals of African/Afro‐Caribbean descent show more significant morphological changes, degree of LVH, and ECG abnormalities compared with whites 22. Awareness of such differences is important in order to avoid overdiagnosis of HCM in healthy individuals exhibiting phenotypes that are within physiological limits for their ethnicity.…”

Background— Pathological T-wave inversion (PTWI) is rarely observed on the ECG of healthy athletes, whereas it is common in patients with certain cardiac diseases. All ECG interpretation guidelines for use within athletes state that PTWI (except in leads aVR, III and V1 and in V1–V4 when preceded by domed ST segment in asymptomatic Afro-Caribbean athletes only) cannot be considered a physiological adaptation. The aims of the present study were to prospectively determine the prevalence of cardiac pathology in athletes presenting with PTWI, and to examine the efficacy of cardiac magnetic resonance in the work-up battery of further examinations. Methods and Results— Athletes presenting with PTWI (n=155) were investigated with clinical examination, ECG, echocardiography, exercise testing, 24h Holter ECG, and cardiac magnetic resonance. Cardiac disease was established in 44.5% of athletes, with hypertrophic cardiomyopathy (81%) the most common pathology. Echocardiography was abnormal in 53.6% of positive cases, and cardiac magnetic resonance identified a further 24 athletes with disease. Five athletes (7.2%) considered normal on initial presentation subsequently expressed pathology during follow-up. Familial history of sudden cardiac death and ST-segment depression associated with PTWI were predictive of cardiac disease. Conclusions— PTWI should be considered pathological in all cases until proven otherwise, because it was associated with cardiac pathology in 45% of athletes. Despite echocardiography identifying pathology in half of these cases, cardiac magnetic resonance must be considered routine in athletes presenting with PTWI with normal echocardiography. Although exclusion from competitive sport is not warranted in the presence of normal secondary examinations, annual follow-up is essential to ascertain possible disease expression.

“…Analysis of 12-lead resting ECG observations showed no pathologic changes in all studied subjects. Major ECG changes were considered as training related normal variants in reference to refined criteria (Sheikh, 2014). These findings were as follows in all studied athletes: sinus bradycardia (17 % of all studied subjects; n = 4), incomplete RBBB (30 %; n = 7), early repolarization (65%; n = 15).…”

Taking into account the features of contemporary approach to trainings in team sports, and basketball in particular, issues of cardiovascular health are under consideration. The purpose of the study was to evaluate health issues and physical capacity of amateur high school and professional basketball players in order to prescribe exercise programs to increase their athletic performance without medical risks. The study involved two groups of basketball players of different levels -student team of UrFU (n = 11, age 19,55 ± 1,57 years) and the professional club team of Sverdlovsk region (n = 12, age 24,17 ± 4,76 years). Methods: multifrequency bio-impedance analysis of body composition, 12-lead ECG, the hemodynamic monitoring during the orthostatic and сlinostatic tests), and cycle exercise testing (ET) with heart rate monitoring and gas-exchange measurement, statistical analysis. Findings: despite the observed normal physical status of subjects, disorders of cardiovascular adaptation were found. The research revealed the insufficient hemodynamic indices (SI & EDI) in students, that lead to higher HR at rest and during ET regardless of the level of intensity. Professional basketball players demonstrated higher ET results (AT = 83.5±6.77 %, P max = 381.5 ± 41.44 W, VE=141.4±38.14) in comparison to students (73.7±8.93%, = 317.09 ± 49.18 W and 115.8±31.9 accordingly). So the development of the cardiovascular system must be the first priority for healthsaving even in basketball, which is basically not considered as endurance sport.
