Abstract：Objective:To explore the effects of high—intensity aerobic intermittent exercise combined with dual—heart intervention on changes in reactive oxygen metabolites(d—ROM)in elderly patients with chronic ejection frac-tion—preserved heart failure.Methods:From July 2021 to July 2023,90 elderly patients with chronic heart failure with preserved ejection fraction were selected and divided into control group and observation group according to random table method,with 45 cases in each group.The control group was given high—intensity aerobic interval exercise plus routine intervention,while the observation group was given high—intensity aerobic interval exercise plus double—hearted inter-vention.Cardiac function indexes,d—ROM changes and quality of life were observed in the two groups.Results:Before intervention,there was no statistically significant difference in the levels of high—sensitivity cardiac troponin T(hs—cTnT),N—terminal B—type natriuretic peptide precursor(NT—proBNP),left ventricular ejection fraction(LVEF),left ventricular end diastolic diameter(LVEDD),as well as emotional,cognitive,role,social,and physical function scores between the two groups(P＞0.05).The levels of hs—cTnT,NT—proBNP,LVEDD and d—ROM in the two groups were lower than those before the intervention,and the observation group was lower than the control group,the difference was statistically significant(P＜0.05).After the intervention,the hs—cTnT in the two groups was lower than that before the intervention,and that in the observation group was lower than that in the control group,with sta-tistical significance(P＜0.05).Conclusion:The combination of high—intensity aerobic intermittent exercise and dual—heart intervention can improve cardiac function in elderly patients with chronic ejection fraction—preserved heart fail-ure,reduce the impact on d—ROM,and improve the quality of life.
