We evaluated the prevalence of left ventricular hypertrophy in elite footballers compared with sedentary controls. A total of 141 elite male professional footballers and 32 healthy sedentary controls were studied. Echocardiographic and demographic variables were compared between groups by unpaired t-test.
The prevalence of left ventricular hypertrophy with maximal wall thickness values out with the normal range (>12 mm) was noted. Footballers were significantly younger than controls (20.9 vs. 24.3 years, P<0.005: 95% CI (-5.2, -1.73)) but there were no significant differences in height, weight or body surface area between the groups. Each of inter-ventricular septum (10.4 vs. 9.1 mm, P<0.0001; 95% CI (0.88, 1.72)), posterior wall (9.2 vs. 8.5 mm, P<0.01; 95% CI (0.22, 1.21)), left ventricular cavity (systolic and diastolic) (34.5 vs. 28.4 mm, P<0.0001; 95% CI (4.31, 7.76) in systole; 50.1 vs. 48.2 mm, P<0.05; 95% CI (0.15, 3.74) in diastole), aortic root size (29.1 vs. 27.8 mm, P<0.05; 95% CI (0.03,2.49)) and left ventricular mass index (112 vs. 89 g/m2, P<0.0001; 95% CI (14.4, 32.1)) were significantly greater in footballers than in controls. Absolute left ventricular wall thickness >12 mm was present in 17 footballers (12%) (range 13-15 mm) and in no controls.
Elite professional footballers have increased cardiac dimensions compared with healthy controls. The prevalence of absolute wall thicknesses out with the normal range is relatively high.
我们评估了精英足球运动员与久坐不动的对照组相比左心室肥厚的患病率。共研究了141名精英男性职业足球运动员和32名健康的久坐不动的对照组。通过不成对t检验比较两组之间的超声心动图和人口统计学变量。
发现左心室肥厚的患病率，其最大壁厚值超出正常范围（>12毫米）。足球运动员比对照组明显年轻（20.9岁对24.3岁，P<0.005；95%可信区间（-5.2，-1.73）），但两组之间在身高、体重或体表面积方面没有显著差异。足球运动员的室间隔（10.4毫米对9.1毫米，P<0.0001；95%可信区间（0.88，1.72））、后壁（9.2毫米对8.5毫米，P<0.01；95%可信区间（0.22，1.21））、左心室腔（收缩期和舒张期）（收缩期34.5毫米对28.4毫米，P<0.0001；95%可信区间（4.31，7.76）；舒张期50.1毫米对48.2毫米，P<0.05；95%可信区间（0.15，3.74））、主动脉根部大小（29.1毫米对27.8毫米，P<0.05；95%可信区间（0.03，2.49））和左心室质量指数（112克/平方米对89克/平方米，P<0.0001；95%可信区间（14.4，32.1））均显著大于对照组。17名足球运动员（12%）存在绝对左心室壁厚度>12毫米（范围13 - 15毫米），而对照组中无此情况。
与健康对照组相比，精英职业足球运动员的心脏尺寸增大。绝对壁厚超出正常范围的患病率相对较高。
