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.

BACKGROUND: Immunotherapies such as adoptive immune cell infusion and immune-modulating agents are widely used for cancer treatment, and the concomitant symptoms, including cytokine release syndrome (CRS) or immune-related adverse events (irAEs), are frequently reported. However, clinical manifestations induced by mismatched donor granulocyte colony-stimulating factor mobilized peripheral blood mononuclear cell (GPBMC) infusion in patients receiving microtransplant (MST) have not yet been well depicted. METHODS: We analyzed 88 cycles of mismatched GPBMC infusion in patients with acute myeloid leukemia receiving MST and 54 cycles of chemotherapy without GPBMC infusion as a comparison. Clinical symptoms and their correlation with clinical features, laboratory findings, and clinical response were explored. RESULTS: Fever (58.0% [51/88]) and chills (43.2% [38/88]) were the significant early-onset symptoms after GPBMC infusion. Patients possessing less human leukocyte antigen-matching loci with the donor or those with unrelated donors experienced more chills (3 [2-5] loci vs. 5 [3-5] loci, P  = 0.043 and 66.7% [12/18] vs. 37.1% [26/70], P  = 0.024). On the other hand, those with decreased CD4 + /CD8 + T-cell ratio developed more fever (0.8 [0.7-1.2] vs. 1.4 [1.1-2.2], P  = 0.007). Multivariable analysis demonstrated that younger patients experienced more fever (odds ratio [OR] = 0.963, 95% confidence interval [CI]: 0.932-0.995, P  = 0.022), while patients with younger donors experienced more chills (OR = 0.915, 95% CI: 0.859-0.975, P  = 0.006). Elevated ultra-sensitive C-reactive protein levels in the absence of cytokine storm were observed following GPBMC infusion, which indicated mild and transient inflammatory response. Although no predictive value of infusion-related syndrome to leukemia burden change was found, the proportion of host pre-treatment activated T cells was positively correlated with leukemia control. CONCLUSIONS Mismatched GPBMC infusion in MST induced unique infusion-related symptoms and laboratory changes, which were associated with donor- or recipient-derived risk factors, with less safety and tolerance concerns than reported CRS or irAEs.
