| Background:The morbidity and mortality of coronary heart disease(CHD)continue to rise,which seriously threatens human health and has a serious impact on patients’ quality of life.Although percutaneous coronary intervention(PCI)is an important means of cardiology for coronary heart disease and revascularization,it does not reverse or delay the biological process of atherosclerosis.The possibility of re-stenosis or thrombosis may still occur after surgery,which has a serious impact on the long-term efficacy of patients,leading to serious quality of life problems and negative economic impacts.Cardiac rehabilitation can improve the prognosis of patients,but the hospital’s cardiac rehabilitation has many inconveniences resulting in low patient participation and compliance.Home based cardiac tele-rehabilitation is a new type of out-of-hospital intelligent perception rehabilitation mode,which is not limited by time and space,and is inexpensive and convenient.At present,there is no clear definition of home based cardiac tele-rehabilitation in China,and the content of specific intervention measures and monitoring means are not the same.The effects of cardiac tele-rehabilitation on improving patients’ quality of life,cardiac function and sports endurance and reducing patients’ disease burden still need to be further explored.Objective:(1)In this study,an experimental study of home-based cardiac tele-rehabilitation of patients with coronary artery disease after PCI was conducted to further explore the influence of this new tele-rehabilitation mode on patients’ quality of life,disease burden status,cardiac function and exercise endurance,for clinical application of home-based cardiac tele-rehabilitation to provide theoretical support and basis.(2)To analyse the influencing factors of patients’ quality of life under the home-based cardiac tele-rehabilitation mode,and provides theoretical support and basis for improving the rehabilitation management mode.Methods: Using the method of convenience sampling,106 patients who met the inclusion and exclusion criteria after PCI in a tertiary hospital in Shiyan city,Hubei province from January 2019 to May 2019 were randomly divided into the control group and the experimental group,there were 53 patients in each group.The control group was treated with conventional rehabilitation therapy,while the experimental group was given home-based cardiac tele-rehabilitation therapy for 3 months.6 minutes walking test(6MWT),anerobic threshold(AT)、VO2max and left ventricular ejection fraction(LVEF)were measured at the time of discharge,8 weeks and 12 weeks after intervention,respectively.At the same time,quality of life scale(SF-12)and family burden of disease scale(FBS)were used to evaluate the quality of life and disease burden of the two groups,so as to evaluate the clinical effect of home-based cardiac tele-rehabilitation and analyse the influencing factors of patients’ quality of life under the home-based cardiac tele-rehabilitation mode.Results:(1)The comparison of the treatment effect,interaction effect and time effect of 6MWT,AT and VO2 max on the exercise endurance of the two groups was statistically significant(P<0.05).(2)Comparison of effect,interaction effect,time effect of PCS and MCS score between the two groups showed statistically significant difference(P<0.05).(3)There was a statistically significant difference in the time effect of ejection fraction between the two groups(P<0.05),and no statistically significant difference in the effect and interaction between the two groups(P >0.05).(4)FBS scores of the two groups were compared in terms of intergroup effect,interaction effect and time effect,and the differences were statistically significant(P<0.05).(5)Univariate analysis was performed for the experimental group,there were statistically significant differences in the PCS score of quality of life scale in age,medical payment,education,exercise and cardiac function grading(P<0.05);There were Statistical significance differences in the MCS score of quality of life scale in age,medical payment,education,exercise,cardiac function grading,number of stent implantation and course of disease(P<0.05).(6)Multiple linear regression analysis showed that age,heart function classification,education level and exercise situation were the main influencing factors for the change of PCS score,and age,course of disease,education level and exercise situation were the main influencing factors for the change of MCS score.Conclusion:(1)Home-based cardiac tele-rehabilitation can improve the quality of life,exercise endurance and can help to reduce the disease burden status on patients after PCI.(2)There are many factors influencing the quality of life of patients with coronary heart disease after PCI based on home-based cardiac tele-rehabilitation mode,which suggests that individualized intervention measures and health education should be carried out for patients with coronary heart disease after PCI. |
