弹力带抗阻训练对急性心肌梗死患者经皮冠状动脉介入术后对心功能的影响

Elastic bandresistance training improves the cardiac function in patients with acute myocardial infarction after percutaneous coronary intervention

目的探讨弹力带抗阻训练对经皮冠状动脉介入（PCI）支架术后的急性心肌梗死患者心功能的影响。方法选择我院2016年1月到6月住院的符合纳入标准的急性心肌梗死支架置入术后患者64例，采用随机数字表法分为康复组30例和对照组34例，对照组接受常规治疗与指导，康复组在对照组的基础上联合抗阻运动，采用弹力带训练。6个月后观察两组患者心功能情况以及每天胸部不适发生次数及时长。结果干预6个月后，康复组6min步行实验（6MWT）[（530．9±39．9）M和（328．3±26．8）m，（t=24．104，P〈0．01）]；康复组≥50％左室射血分数（LVEF）患者比例t83．3％和50％（χ^2=7．850，P〈0．01）]均高于对照组；康复组平均每天胸部不适发生次数及持续时长比例均低于对照组（χ^2=11．563、9．067，均P〈0．01）。结论抗阻训练可明显改善心肌梗死支架术后患者心功能情况，在临床可推广应用。

Objective To investigate the influence of elastic band resistance training on cardiac function in patients with acute myocardial infarction （AMI） after percutaneous coronary intervention （PCI）. Methods 64 hospitalized patients with acute myocardial infarction after PCI from January 20J6 to June 2016, were randomly divided into two groupS： rehabilitation group （n = 30） and control group （n = 34）. The control group received a routine treatment and guidance, rehabilitation group received elastic band training as add-on therapy to above routine treatment and guidance. After 6 months of therapy, cardiac function, the number of daily chest discomfort and its duration were compared between two groups. Results After six months of therapy, 6MWT [（ 530.9 ± 39.9） m versus （328.3±26.8）m,（t=24. 104,P〈0.01）land LVEF ≥50%[n（%））（83.3% versus 50% ）（χ^2 =7. 850,P〈 0.01）were significantly higher in the rehabilitation group than in control group,with statistically significant difference （t = 24. 104, χ^2 = 7. 850, all P 〈 0.01 ） . In addition, an average number of daily chest discomfort （χ^2 = 11. 563, P〈 0.01） and its duration （χ^2= 9. 067,P〈 0. 05） were obviously improved in rehabilitation group than in control group, with statistically significant difference. Conclusions Anti-resistance training can significantly improve the cardiac function of patients with acute myocardial infarction after PCI and can be applied in clinical practice.
