运动员心力储备检测和评估的一种无创性方法研究

“心音图运动实验”(PCGET)是新近提出和进行的一项心肌收缩能力以及心血管病人和健康人的心力储备评估方法。为了评估 PCGET方法在体育运动学中的应用价值 ,作者进行了该方法的临床研究 ,把运动后第一心音幅值对安静时第一心音幅值的倍数定义为心肌收缩能力储备指数 (Myocardial contractility reserve index,CCRI)。对 30例运动员和 30例普通健康人分别做了心音图运动试验 ,结果显示 ,30例运动员的 CCRI平均值为 :10 .139± 2 .6 31,30例普通健康人的 CCRI平均值为 :6 .6 12± 3.10 4 ,表明这两组 CCRI数据间存在显著性差异 (P<0 .0 1)。鉴于此 ,PCGET可作为运动员心力储备的无创、简便、快速的量化测评方法。

A Noninvasive Method for Measuring and Evaluating Cardiac Reserve of Athletes

Phonocardiogram exercise testing(PCGET) is a recently developed method for evaluating cardiac contractility and the cardiac reserve of patients with heart disease and of healthy subjects. In order to test the reliability of PCGET method in physical sport, the present author conducted a clinical study. The ratio of the amplitude of the first heart sound after PCGET to that recorded at rest was defined as an indicator, i.e. cardiac contractility reserve index (CCRI). PCGET was performed on 30 athletes and 30 non-athletes. The results showed that the average of CCRI was 10.139 +/- 2.631 in 30 athletes and 6.612 +/- 3.104 in 30 non-athletes. There was a significant difference between CCRI of the two groups (P < 0.01). Thus, PCGET might be a noninvasive, convenient and inexpensive technique to evaluate the cardiac reserve quantitatively for athletes.
