The effect of different exercise intensities on long-term frailty in STEMI patients
Objective To clarify the effect of different exercise intensities on long-term frailty in ST el-evation myocardial infarction(STEMI)patients.Methods A tatal of 688 STEMI patients admitted to our hospital between January 2019 and December 2022 were continuously included.Based on their weekly exercise intensity,the patients were divided into the standard-intensity group and the low-intensity group,344 cases in each group.Collected basic information during hospitalization and conducted long-term follow-up.Used the FRAIL frailty assessment scale to evaluate long-term frailty and cardiovascular outcomes.Results The aver-age follow-up time was(2.63±0.41)years,and the incidence rate of frailty was 27.9%.The proportion of men,the level of weekly exercise days and daily exercise time was higher(P<0.05)in the standard-intensity group.During follow-up,the standard-intensity group had a lower incidence of angina and frailty,a higher pro-portion of grade in NYHA heart function classification,and a lower level of FRAIL frailty score(P<0.001).Multivariate logistic regression analysis showed that age,diabetes history,weekly exercise days and daily exer-cise time may have an independent impact on the occurrence of long-term frailty in STEMI patients(P<0.05).Based on this,a prediction model of long-term frailty in STEMI patients was constructed,and the model was effective in predicting the occurrence of frailty(AUC=0.697,95%CI 0.618-0.775,P<0.001).Conclusion Standard intensity exercise outside the hospital for STEMI patients can reduce the occurrence of long-term frailty and improve patient prognosis.Medical staff should further strengthen the promotion and guidance of exercise rehabilitation for STEMI patients.
