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

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 2016 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)〕and LVEF ≥50%〔n(%)〕(83.3% versus 50% )(χ2=7.850, P< 0.01)were significantly higher in the rehabilitation group than in control group, with statistically significant difference (t=24.104, χ2=7.850, all P< 0.01). In addition, an average number of daily chest discomfort (χ2=11.563, P< 0.01) and its duration (χ2=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.
