Abstract:
Objective To determine the impact of progressive rehabilitation intervention based on the FITT principle on the recovery of elderly patients with acute ST-segment elevation myocardi-al infarction(STEMI)after percutaneous coronary intervention(PCI).Methods A total of 184 STEMI patients admitted to our hospital between December 2021 and June 2023 were enrolled and randomly divided into a study group(n=92)and a control group(n=92).Routine rehabilita-tion intervention was given to the control group,and progressive rehabilitation intervention based on the FITT principle was given to the study group.Both groups were intervened for 12 weeks.Metabolite equivalents(MET)of the two groups were evaluated before and at 4,8 and 12 weeks after intervention.Their cardiopulmonary reserve function and quality of life were evaluated with cardiopulmonary exercise testing and myocardial infarction multidimensional assessment scale(MIDAS)before and at 12 weeks after intervention.The incidence of adverse cardiovascular events such as ventricular arrhythmia and heart failure(HF)during 6 months of follow-up was recorded.Results There were significant differences in two sets of MET value groups,time points,and group time point interactions(P＜0.01).No statistical difference was found in MET values be-tween the two groups before intervention(P＞0.05).The MET values were increased in both groups at 4,8 and 12 weeks after intervention than before intervention,and those in the study group were higher than those in the control group at above three time points(P＜0.05).Com-pared with before intervention,the peak oxygen uptake and anaerobic threshold oxygen uptake in 2 groups increased after intervention(P＜0.05).The peak oxygen uptake and anaerobic threshold oxygen uptake in the study group were higher than those in the control group[(23.52±1.86)ml/(min·kg)vs(21.36±2.60)ml/(min·kg),P＜0.01;(14.33±2.02)ml/(min·kg)vs(12.08±1.76)ml/(min·kg),P＜0.01];Compared with before intervention,the carbon dioxide ventilation equivalent slope of 2 groups decreased after intervention(P＜0.05).The carbon dioxide equivalent slope of the study group was lower than that of the control group(26.12±2.34 vs 28.10±2.52,P＜0.01).Compared with before intervention,the MIDAS score was decreased in both groups af-ter intervention(65.30±5.20 vs 96.64±7.33,P＜0.01;70.46±5.87 vs 95.80±7.26,P＜0.01),and the score of the study group was lower than that of the control group(65.30±5.20 vs 70.46±5.87,P＜0.01).After a 6-month follow-up,there was no significant difference in the incidence of adverse cardiovascular events between the two groups(P＞0.05).Conclusion Progressive reha-bilitation interventions based on the FITT principle can promote exercise tolerance,improve car-diopulmonary reserve function,and enhance the quality of life of elderly STEMI patients after PCI.
