To examine the cardiac structure and function of Arabic athletes and to establish if the European Society of Cardiology (ESC) guidelines for the interpretation of an athlete's ECG are applicable to this ethnicity.
600 high-level Arabic, 415 Black African, 160 Caucasian male athletes (exercising ≥6 h/week) and 201 Arabic controls presented for ECG and echocardiographic screening.
9 athletes (0.7%) were identified with a cardiac pathology associated with sudden cardiac death. Two Arabics (0.3%) and five Black Africans (1.2%) were diagnosed with hypertrophic cardiomyopathy; a prevalence four times greater in Black African compared to Arabic athletes. Arabic athletes had significantly greater (p<0.05) left ventricular (LV) end-diastolic diameters, maximal LV wall thicknesses and LV mass compared with controls; yet were significantly smaller than Black African and Caucasian athletes. The percentage of athletes demonstrating LV hypertrophy (≥12 mm) was comparable between Arabic, Black African and Caucasian populations (0.5%, 0.5% and 0.6%, respectively). There was no difference in the frequency of an uncommon and training-unrelated ECG between Arabic and Caucasian. However, Black Africans demonstrated a significantly greater prevalence than Arabic and Caucasian athletes (20% vs 8.4% and 6.9%, p<0.001); specifically more right/left atrial enlargement and T wave inversion.
Arabic athletes present significantly smaller cardiac dimensions than Black African and Caucasian athletes. There was no significant difference between the frequency of an uncommon and training-unrelated ECG between Arabic and Caucasian athletes. Therefore, the use of ESC guidelines for the interpretation of an athlete's ECG is clinically relevant and acceptable for use within Arabic athletes.
检查阿拉伯运动员的心脏结构和功能，并确定欧洲心脏病学会（ESC）关于运动员心电图解读的指南是否适用于这一人群。
600 名高水平阿拉伯男性运动员、415 名黑非洲男性运动员、160 名白种人男性运动员（每周运动≥6 小时）和 201 名阿拉伯对照组接受心电图和超声心动图筛查。
9 名运动员（0.7%）被发现存在与心源性猝死相关的心脏病理。2 名阿拉伯人（0.3%）和 5 名黑非洲人（1.2%）被诊断为肥厚型心肌病；黑非洲运动员的患病率是阿拉伯运动员的 4 倍。阿拉伯运动员的左心室（LV）舒张末期直径、最大 LV 壁厚度和 LV 质量明显大于对照组（p<0.05）；但明显小于黑非洲和白种人运动员。表现为 LV 肥厚（≥12mm）的运动员比例在阿拉伯人、黑非洲人和白种人之间相似（分别为 0.5%、0.5%和 0.6%）。阿拉伯人和白种人之间不常见的且与训练无关的心电图的频率没有差异。然而，黑非洲人表现出明显高于阿拉伯人和白种人的患病率（20%比 8.4%和 6.9%，p<0.001）；特别是右/左心房扩大和 T 波倒置更为常见。
阿拉伯运动员的心脏尺寸明显小于黑非洲和白种人运动员。阿拉伯和白种人运动员之间不常见的且与训练无关的心电图的频率没有显著差异。因此，ESC 指南用于解释运动员心电图具有临床相关性，并且可以在阿拉伯运动员中使用。
