Over the past several years interest regarding the causes of sudden deaths in young trained athletes has heightened in the medical community. 36% of sudden cardiac death (SCD) in young competitive athletes is due to hypertrophic cadiomyopathy (HCM), while 10% of SCD cases in sports are due to increased cardiac mass without signs of HCM. The goal of this study was to evaluate systolic and diastolic functions, and to determine the clinical significance of electrocardiographic patterns in highly trained football players with increased left ventricular mass index (LVMI) > 125g/m(2). 221 highly trained male football players were studied, among them 46 with increased LVMI. M, 2D, Doppler echocardiography and resting and exercise electrocardiography were performed. Various cardiovascular abnormalities were found by echocardiography in 12 athletes (5,4%). Systolic and diastolic functions of the heart were within normal limits. Increased left ventricular mass in the football players was often associated with abnormal ECG patterns (47,8%). Abnormal ECGs were found in 85,7% of football players with concentric hypertrophy. The group of athletes with both increased LVMI and abnormal ECG patterns need further evaluation and observation. ECG and echocardiography should be included in the PPS protocol of the highly trained football players to prevent SCD in young athletes.
在过去几年里，医学界对年轻训练有素的运动员猝死原因的关注度有所提高。年轻竞技运动员中36%的心源性猝死（SCD）归因于肥厚型心肌病（HCM），而运动中10%的SCD病例是由于心脏质量增加但无HCM迹象。本研究的目的是评估收缩和舒张功能，并确定左心室质量指数（LVMI）>125g/m²的高度训练的足球运动员心电图模式的临床意义。对221名高度训练的男性足球运动员进行了研究，其中46名LVMI增加。进行了M型、二维、多普勒超声心动图以及静息和运动心电图检查。超声心动图在12名运动员（5.4%）中发现了各种心血管异常。心脏的收缩和舒张功能在正常范围内。足球运动员左心室质量增加通常与异常心电图模式相关（47.8%）。在85.7%的向心性肥厚足球运动员中发现了异常心电图。LVMI增加且心电图模式异常的运动员组需要进一步评估和观察。心电图和超声心动图应纳入高度训练的足球运动员的PPS方案中，以预防年轻运动员的SCD。
