The present study investigated the relationship between arterial stiffness and left ventricular diastolic function in endurance-trained athletes. Sixteen young male endurance-trained athletes and nine sedentary of similar age men participated in this study. Resting measures in carotid-femoral pulse wave velocity were obtained to assess arterial stiffness. Left ventricular diastolic function was assessed using 2-dimensional echocardiography. The athletes tended to have lower arterial stiffness than the controls (P=0.071). Transmitral A-waves in the athletes were significantly lower (P=0.018) than the controls, and left ventricular mass (P=0.034), transmitral E-wave/A-wave (P=0.005) and peak early diastolic mitral annular velocity at the septal site (P=0.005) in the athletes were significantly greater than the controls. A significant correlation was found between arterial stiffness and left ventricular diastolic function (E-wave: r=- 0.682, P=0.003, E-wave/A-wave: r=- 0.712, P=0.002, peak early diastolic mitral annular velocity at the septal site: r=- 0.557, P=0.025) in the athletes, whereas no correlation was found in controls. These results suggest that lower arterial stiffness is associated with higher left ventricular diastolic function in endurance-trained athletes.
本研究调查了耐力训练运动员的动脉僵硬度与左心室舒张功能之间的关系。16名年轻男性耐力训练运动员和9名年龄相仿的久坐男性参与了本研究。通过测量静息状态下的颈股脉搏波速度来评估动脉僵硬度。使用二维超声心动图评估左心室舒张功能。运动员的动脉僵硬度往往低于对照组（P = 0.071）。运动员的二尖瓣A波显著低于对照组（P = 0.018），而运动员的左心室质量（P = 0.034）、二尖瓣E波/A波（P = 0.005）和室间隔部位舒张早期二尖瓣环峰值速度（P = 0.005）显著高于对照组。在运动员中，动脉僵硬度与左心室舒张功能之间存在显著相关性（E波：r = -0.682，P = 0.003；E波/A波：r = -0.712，P = 0.002；室间隔部位舒张早期二尖瓣环峰值速度：r = -0.557，P = 0.025），而在对照组中未发现相关性。这些结果表明，在耐力训练运动员中，较低的动脉僵硬度与较高的左心室舒张功能相关。
