Integrated body rheography, radiocardiography and radionuclide ventriculography were used to investigate hemodynamic changes in 101 myocardial infarction patients during the hospital stage of the disease. Changes in major hemodynamic parameters were demonstrated by the end of the 1st week and when walking was resumed. At the resumed-walking stage, the mechanism of declining stroke and cardiac indices was shown to depend on physical activation rates. Hemodynamic response is mostly conditioned by myocardial insufficiency when walking is resumed rapidly during the 2nd week, and by smaller venous return due to hypovolemia where it is resumed slowly during the 4th week. Expanding motion regimens at slow rates results in persistent hemodynamic disturbances in myocardial infarction patients.
采用综合人体电阻抗描记法、心放射图法和放射性核素心室造影法，对101例心肌梗死患者在疾病住院阶段的血流动力学变化进行了研究。主要血流动力学参数的变化在第1周结束时以及恢复行走时得以体现。在恢复行走阶段，心搏量和心脏指数下降的机制表明取决于身体活动速率。当在第2周快速恢复行走时，血流动力学反应主要由心肌功能不全所决定；而当在第4周缓慢恢复行走时，则由血容量不足导致静脉回心血量减少所决定。心肌梗死患者以缓慢速率扩大运动方案会导致持续性血流动力学紊乱。
