Deformation analysis using 2-dimensional strain echocardiography can detect early systolic function abnormalities in patients with left ventricular hypertrophy. This study was designed to characterize global and regional myocardial deformation using 2-dimensional strain in professional soccer players (PSPs) compared with control subjects and patients with hypertrophic cardiomyopathy (HC). Twenty nine PSPs, 26 patients with HC, and 17 controls were investigated at rest using transthoracic echocardiography with 2-dimensional strain analysis. Radial and transverse strains were significantly higher in PSPs compared with controls, whereas longitudinal strain was lower. Compared with patients with HC, athletes had higher values for transverse, radial, and circumferential strains. In pathologic hypertrophic segments, longitudinal strain was lower in patients with HC than in PSPs. In conclusion, 2-dimensional strain can identify specific patterns of myocardial deformation in PSPs, controls, and patients with HC. It has the potential to become a routinely used method for the differentiation of athlete's heart and HC.
使用二维应变超声心动图进行变形分析能够检测出左心室肥厚患者早期的收缩功能异常。本研究旨在通过二维应变来描述职业足球运动员(PSP)的整体和局部心肌变形特征,并与对照组以及肥厚型心肌病(HC)患者进行比较。对29名职业足球运动员、26名肥厚型心肌病患者和17名对照者进行静息状态下的经胸超声心动图检查及二维应变分析。与对照组相比,职业足球运动员的径向应变和横向应变显著更高,而纵向应变更低。与肥厚型心肌病患者相比,运动员的横向、径向和圆周应变值更高。在病理性肥厚节段,肥厚型心肌病患者的纵向应变低于职业足球运动员。总之,二维应变能够识别职业足球运动员、对照组和肥厚型心肌病患者心肌变形的特定模式。它有可能成为区分运动员心脏和肥厚型心肌病的常规使用方法。
