Abstract：Objective To discuss the influence of heart rehabilitation on myocardial microcirculation,exercise ability and quality of life(QOL)in patients with acute myocardial infarction(AMI)after percutaneous coronary intervention(PCI).Methods AMI patients(n=120)undergone PCI were chosen from the First Hospital of Handan City from Sept.2021 to Jun.2022,and all patients were divided into test group(each n=63)and control group(n=57)by using random digital table.The control group was given routine therapy after PCI and test group was additionally given heart rehabilitation after PCI.The clinical efficacy,myocardial microcirculation perfusion,left ventricular ejection fraction(LVEF),6-minute walk test(6MWT),total physical content score(PCS),total mental content score(MCS)and cardiac complications were compared between 2 groups.Results The total effective rate was significantly higher in test group than that in control group(85.71％vs.70.18％,P＜0.05).The difference in level of myocardial microcirculation perfusion had no statistical significance between 2 groups before treatment(P＞0.05).After treatment,level of myocardial microcirculation perfusion increased in 2 groups(P＜0.05),which was more significant in test group(P＜0.05).The indexes of LVEF and 6MWTincreased in 2 groups(P＜0.05),which was more significant in test group(P＜0.05).After treatment,MCS and PCSincreased in 2 groups(P＜0.05),which was more significant in test group(P＜0.05).During treatment,the main adverse cardiac reactions included angina pectoris,heart failure and arrhythmia,and incidence of adversereactions had statistical difference between 2 groups(P＜0.05).Conclusion The heart rehabilitation has a higher curative effect in AMI patients after PCI,which may effectively improve levels of myocardial microcirculation,exercise ability and QOL.
