15例心肌梗塞恢复期或心绞痛患者在一段时间的体育训练前后进行自行车测力计最大努力试验和血流动力学及血管造影检查。训练计划包括每周60至75分钟的三次训练，持续两个月。最大努力试验表明，体能提高了17%（P < 0.02），在同样的努力量下，心率下降了13%，血压下降了7%（P < 0.01）。血流动力学和血管造影检查显示，在总组、收缩力明显受损的患者、或有大面积运动障碍或广泛运动不能的患者中，训练后左心室舒张末期压、心室容积、射血分数、VCF、缩短百分比和节段性收缩力均无显著变化。结论：训练对心肌无直接影响，无论是有益的还是有害的。
Fifteen subjects recovering from a myocardial infarction or suffering from angina were given a maximum effort test on a bicycle ergometer and hemodynamic and angiographic investigations before and after a period of physical training. The training program consisted of three sessions of 60 to 75 min each week for two months. Maximum effort tests showed that physical capacity had increased by 17%(P < 0.02) and that for the same amount of effort the heart rate had decreased by 13% and the blood pressure by 7% (P < 0.01). Hemodynamic and angiographic investigations showed no significant changes after training in the left ventricular end-diastolic pressure, ventricular volume, ejection fraction, VCF, percentage of shortening and segmental contractility, in the total group, in those patients whose contractility was considerably impaired, or in those who had large dyskinetic areas or widespread akinesia. It is concluded that training had no directinfluence on the myocardium, either beneficial or detrimental.
