The aim of this study was to evaluate the diastolic function in athletes and in young borderline hypertensives with mild left ventricular hypertrophy. Left ventricular filling was assessed by echo Doppler measurement of transmitral flow velocity in 18 soccer players (age 22 +/- 4 years, left ventricular mass index, LVMI 136 +/- 12 g/m2), in 15 borderline hypertensives (age 21 +/- 3 years, LVMI 137 +/- 9 g/m2), and 20 normotensive subjects (age 22 +/- 4 years, LVMI 93 +/- 10 g/m2) as reference group. We found that left ventricular filling profile was similar in borderline hypertensives, in athletes and in normotensive subjects. These findings suggest that, at least in the early stage, mild cardiac hypertrophy secondary to borderline blood pressure elevation is characterized by indexes of diastolic function not different from those found in athletes with physiological hypertrophy.
本研究的目的是评估运动员以及伴有轻度左心室肥厚的年轻临界高血压患者的舒张功能。通过超声多普勒测量二尖瓣血流速度来评估左心室充盈情况，研究对象包括18名足球运动员（年龄22±4岁，左心室质量指数，LVMI 136±12 g/m²）、15名临界高血压患者（年龄21±3岁，LVMI 137±9 g/m²）以及20名血压正常的受试者（年龄22±4岁，LVMI 93±10 g/m²）作为参照组。我们发现临界高血压患者、运动员以及血压正常的受试者的左心室充盈情况相似。这些发现表明，至少在早期阶段，继发于临界血压升高的轻度心脏肥厚的舒张功能指标与生理性肥厚的运动员并无差异。
