| ObjectiveObjective to investigate the effect of external counterpulsation at Meridian-acupoints on cardiac rehabilitation after PCI in patients with acute myocardial infarction.MethodsA randomized,controlled,and balanced clinical trial design was used to include 113 patients with acute myocardial infarction who were successfully treated with PCI(excluding 20 patients),and finally 93 patients were included.The patients were randomly divided into three groups:the Meridian-acupoints group(31 patients),the control group(30 patients),and the blank group(32 patients).Meridian-acupoints group:on the basis of conventional western medicine treatment combined with in vitro counterpulsation treatment at the same time to add acupoint stimulation;Control group:on the basis of conventional treatment of western medicine combined with in vitro counterpulsation therapy;The blank group received conventional western medicine treatment.Through-hole group and control group for 20 consecutive days through-hole with conventional treatment of ecp ecp,three groups respectively in 2 days and 20 days after complete TCM symptoms curative effect integral,anxiety scale score,depression rating scale and cardiopulmonary exercise testing,the adverse reaction of the test process of data collection,statistics processing.Results1.Curative effect and integral points of TCM syndromesIn terms of TCM symptoms,the total effective rate of the three groups was 87.1%in the meridian point group,76.67%in the control group,and 59.37%in the blank group,respectively.There was no significant difference between the meridian point group and the control group(P>0.05),significant difference between the meridian point group and the blank group(P<0.05),and no significant difference between the control group and the blank group(P>0.05).2.Mental state integralThere was no significant difference in anxiety scores between the three groups before treatment(P>0.05),which was comparable.After treatment,anxiety scores in the Meridian-acupoints group,control group and blank group were:(4.29 2.94),(8.03 3.32)and(8.03 3.47),respectively.After treatment,there were significant differences in anxiety scores between each group(P<0.05),and there were significant differences between the-point group and the control group(P<0.05).There was no significant difference in depression scores among the three groups before treatment(P>0.05),which was comparable.After treatment,anxiety scores in the Meridian-acupoints group,control group and blank group were:(3.87 1.63),(7.8 0.76)and(10.88 1.83),respectively.After treatment,there were significant differences in depression scores between the groups(P<0.05),and there were significant differences between the Meridian-acupoints group and the control group(P<0.05).3.Heart-lung exercise testUnder the anaerobic threshold level,the cardiopulmonary exercise values(METs,V02/kg,V02 and vo2-hr)of the three groups were not significantly different before treatment,showing comparability.The data of the Meridian-acupoints group,the control group and the blank group were paired before and after self-examination.There were significant differences between the Meridian-acupoints group and the control group in METs value,V02/kg,V02 and vo2-hr(P<0.05).Compare three sets of data after treatment in the METs value,V02/kg,the change of V02,V02-HR was statistically significant(P<0.05),after comparing the two later,through-hole group compared with control group,the blank group,respectively,were statistically significant(P<0.05);The difference between the three groups before and after treatment was compared.The changes in the median METs value,V02/kg,V02 and vo2-hr were statistically significant(P<0.05).As for the comparison of the parameters at the peak level,the cardiopulmonary exercise values of the three groups as METs,V02/kg,V02 and vo2-hr showed no significant difference before treatment(P>0.05),while the differences in HR and HRR before treatment were significant(P<0.05).After treatment,mean values of METs,V02/kg,V02 and HR in the Meridian-acupoints group increased as compared with the previous group,while mean values of HRR decreased as compared with the previous group.The difference was statistically significant(P<0.05).As for the control group,METs value,V02/kg and V02 increased as compared to the previous level,while HRR mean decreased as compared to the previous level.The difference was statistically significant(P<0.05).In the blank group,vo2-hr and HR increased,while HRR mean decreased(P<0.05).After treatment,the difference in METs value,V02/kg,V02,HR and HRR between the groups was statistically significant(P<0.05).P>0.05 in vo2-hr was not statistically significant.The post-treatment data were compared by pairwise afterwards.In the comparison of METs value,V02/kg,V02,VC02,HR and HRR,the Meridian-acupoints group was superior to the control group and the blank group(P<0.05),while the control group was superior to the blank group(P<0.05).The difference analysis of the three groups of data showed that METs value,V02/kg,V02,HRR and vo2-hr were significantly different(P<0.05),while HR was not significantly different(P>0.05).Conclusion1.Curative effect of TCM symptomsMeridian-acupoints external counterpulsation and conventional external counterpulsation can improve postoperative TCM symptoms score of patients with acute myocardial infarction,and jing-point external counterpulsation is superior to conventional external counterpulsation.2.Psychological status scorethe scores of anxiety and depression can be reduced by the Meridian-acupoints external counterpulsation and conventional external.In addition,external counterpulsation via-point is superior to conventional external counterpulsation.3.Cardiopulmonary functionMeridian-acupoints external counterpulsation and conventional external can improve the METs value,V02/kg,V02 and vo2-hr of patients under anaerobic threshold,and improve the METs value,V02/kg,V02 and HR at the peak level.In addition,extracorporeal counterpulsation via acupoints is superior to conventional extracorporeal counterpulsation. |
