摘　　要：目的　研究分级等长收缩运动对急性心肌梗死 (AMI)患者的心功能影响。方法　对 2 3例中低危组AMI患者进行分级等长收缩握力试验 ,应用Acusow 12 8xP 10彩色多普勒声像仪检测 2 0 %、4 0 %、5 0 %运动负荷的各血流动力学参数。结果　患者运动后 ,心率和平均动脉压较运动前显著增加 ;舒张功能评价指标、左室射血力及左室射血分数较运动前有所降低 ,但 2 0 %运动负荷时无统计学差异 ,4 0 %运动负荷时左室射血分数无显著差异。结论　AMI患者可以进行适当的等长收缩运动 ,运动训练中应注意安全。Objective To explore the effect of isotonic contraction exercise on cardiac function in patients with AMI.Methods Isotonic contraction test was studied in 23 patients with AMI who were in middle-low risk classic.Hemodynamics parameters were determined by color Doppler ultracardiography at 20%,40% and 50% of exercise load.Results After exercise, HR and MBP increased significantly. E/A,F and EF decreased to some extent.However,no significant difference was observed in EF at 40% of load. When at 50%, there were significant difference in all hemodynamics parameters.Conclusion Patients with AMI can do some appropriate isotonic exercise and should take care of safety and efficiency.
