心脏康复治疗对急性心肌梗死患者心率变异性的影响

目的探讨Ⅰ期心脏康复对急性心肌梗死(AMI)患者心率变异性(HRV)的影响。方法选取我院2016年6月至2018年6月收治的104例急性ST段抬高型心肌梗死(STEMI)患者作为研究对象,按照是否接受院内Ⅰ期心脏康复治疗将其分为观察组(接受心脏康复治疗,48例)和对照组(未接受心脏康复治疗,56例)。比较两组患者的HRV指标、入院时与出院前的心理状态、运动能力。结果观察组患者的SDNN、SDANN、RMSSD、pNN50、VLF、HF均高于对照组(P<0.05);两组患者的LF、LF/HF比较,差异无统计学意义(P>0.05)。出院前,两组患者的SAS评分均低于入院时,且观察组低于对照组(P<0.05)。出院前,观察组患者的心率无氧阈水平高于对照组(P<0.05)。结论Ⅰ期心脏康复能提高STEMI患者的HRV,改善其焦虑情况及运动能力。

Effect of cardiac rehabilitation on heart rate variability in patients with acute myocardial infarction

Objective To explore the effect of stage Ⅰ cardiac rehabilitation on heart rate variability(HRV) in patients with acute myocardial infarction(AMI).Methods A total of 104 patients with acute ST segment elevation myocardial infarction(STEMI) admitted in our hospital from June 2016 to June 2018 were selected as the study objects and divided into observation group(received cardiac rehabilitation treatment,48 cases) and control group(didn’t receive cardiac rehabilitation treatment,56 cases) according to whether patients received the stage Ⅰ cardiac rehabilitation treatment in hospital.The HRV indexes,mental state at admission and before discharge and athletic ability of the two groups were compared.Results The SDNN,SDANN,RMSSD,pNN50,VLF and HF in the observation group were higher than those in the control group(P<0.05);there were no significant differences in the LF and LF/HF between the two groups(P>0.05).Before discharge,the score of SAS in the two groups was lower than that at admission,and that in the observation group was lower than the control group(P<0.05).Before discharge,the heart rate anaerobic threshold level in the observation group was higher than that in the control group(P<0.05).Conclusion Stage Ⅰ cardiac rehabilitation can improve HRV,anxiety and athletic ability of STEMI patients.
