Abstract

Objective: The aim of the study was to explore the individual impact of BMI and height on LV size and geometry in a cohort of healthy athletes.

Methods: From a total cohort of 1857 healthy élite athletes (21 ± 5 years, males 70%) investigated with ECG and echocardiogram, we considered three groups: Group 1 n = 50: BMI ≥ 30 and height < 1.90 m; Group 2 n = 87: height ≥ 1.95 m and BMI < 30; control Group 3 n = 243: height < 1.90 m and BMI = 20-29.

Results: BSA was ≤2.3 m² in 52% of athletes in group 1 and 47% of athletes in group 2. Athletes in group 1 and in group 2 showed an enlarged LV end-diastolic diameter (LVEDD) (57 ± 6 vs 57 ± 4 vs 53 ± 4 mm in Group 3); 50% of athletes in group 1 and 38% of athletes in group 2 exhibited a LVEDD > 57 mm (p = 0.23). LV wall thickness was higher in group 1 (11 ± 1 vs 10 ± 2 mm in Group 2, p = 0.001). Concentric hypertrophy or concentric remodelling was found in 20% of athletes in group 1 vs 7% of athletes in group 2 (p = 0.04). Athletes of group 1 with BSA ≤ 2.3 m² showed lower LVEDD (53 ± 5 vs 60 ± 5 mm, p < 0.001), similar LV wall thickness (10 ± 1 vs 11 ± 1 mm, p = 0.128) and higher prevalence of concentric hypertrophy or concentric remodelling (31% vs 8%, p = 0.04) compared to those with BSA > 2.3 m².

Conclusion: Athletes with high BMI have similar LV dimensions but greater wall thickness and higher prevalence of concentric remodelling compared to very tall athletes. Athletes with high BMI and large BSA have the widest LV dimensions.

以极端人体测量为特征的精英运动员的左心室形态和几何形状。

研究目的本研究旨在探讨体重指数和身高对健康运动员队列中左心室大小和几何形状的个体影响：我们对 1857 名健康精英运动员（21 ± 5 岁，男性占 70%）进行了心电图和超声心动图检查，并将其分为三组：第 1 组 n = 50：体重指数≥ 30，身高结果：第 1 组 52% 的运动员和第 2 组 47% 的运动员的 BSA 均小于 2.3 平方米。第 1 组和第 2 组运动员的左心室舒张末期直径（LVEDD）增大（第 1 组为 57 ± 6 mm vs 第 2 组为 57 ± 4 mm vs 第 3 组为 53 ± 4 mm）；第 1 组 50%的运动员和第 2 组 38%的运动员的左心室舒张末期直径大于 57 mm（P = 0.23）。第 1 组的左心室壁厚度更高（11 ± 1 mm，第 2 组为 10 ± 2 mm，p = 0.001）。第 1 组 20% 的运动员与第 2 组 7% 的运动员相比存在同心性肥厚或同心性重塑（p = 0.04）。BSA≤2.3 m2的第1组运动员的LVEDD较低（53 ± 5 vs 60 ± 5 mm，p 2.3 m2）：高体重指数运动员的左心室尺寸与非常高的运动员相似，但左心室壁厚度更大，同心重塑的发生率更高。高体重指数和大体重指数运动员的左心室尺寸最宽。

期刊介绍： The Hellenic Journal of Cardiology (International Edition, ISSN 1109-9666) is the official journal of the Hellenic Society of Cardiology and aims to publish high-quality articles on all aspects of cardiovascular medicine. A primary goal is to publish in each issue a number of original articles related to clinical and basic research. Many of these will be accompanied by invited editorial comments. Hot topics, such as molecular cardiology, and innovative cardiac imaging and electrophysiological mapping techniques, will appear frequently in the journal in the form of invited expert articles or special reports. The Editorial Committee also attaches great importance to subjects related to continuing medical education, the implementation of guidelines and cost effectiveness in cardiology.
