摘　　要：目的:研究分级等长收缩运动对急性心肌梗死(acutemyocardialinfarc-tion,AMI)患者心功能的影响。方法:对23例AMI患者进行分级等长收缩握力试验,应用Acu-sow-128xP-10彩色多普勒声像仪检测运动负荷20%,40%,50%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,舒张充盈速度早晚期比率(E/A)、左室射血率以及左室射血分数较运动前有所降低。但是运动负荷级别为20%,及运动负荷40%时,左室射血分数运动前后差异有显著性意义(t=1.319,0.858,P<0.05);运动负荷50%时,血流动力学监测指标差异有显著性意义(t=2.508,P<0.05)。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、有效。AIM:To explore the effect of isotonic contraction exercise training on cardiac function in patients with acute myocardial infarction(AMI). METHODS:Isotonic contraction grip test was performed in 23 patients with AMI.Hemodynamics parameters were determined by color Doppler Acusow 128xP 10 ultracardiography at 20%,40%and 50%of exercise load. RESULTS:After exercise,heart rate and mean arterial pressure were increased significantly.Peak E/A,left ventricle ejection and ejection fraction were decreased to some extent as compared with those before exercise.However,there was no significant difference of left ejection fraction at 20%and 40%of exercise load before and after exercise(t=1.319,0.858,P< 0.05).When at 50%,there was significant difference in all hemodynamics parameters(t=2.508,P< 0.05). CONCLUSION:Patients with AMI can do some appropriate isotonic exercise and should take care of safety and efficiency.
