Abstract：Objective To analyze the application effect of quantitative assessment and grading intervention combined with respiratory training in elderly patients with chronic heart failure(CHF).Methods From June 2021 to December 2023,122 elderly CHF patients were randomly divided into the control group(n=61,routine cardiology nursing)and test group(n=61,quantitative assessment and grading intervention combined with respiratory training on the basis of routine cardiology nursing)using a random number table method.Cardiopulmonary function,respiratory muscle strength,quality of life,6-minute walking distance(6MWD),and incidence of major adverse cardiac events(MACEs)were compared.Results After interventions,the peak oxygen uptake(VO2peak),anaerobic threshold,left ventricular ejection fraction(LVEF),forced expiratory volume at 1 second(FEV1),forced vital capacity(FVC),maximum inspiratory pressure(MIP),peak inspiratory flow rate(PIF),and 6MWD of both groups were significantly elevated than pre-intervention values(P<0.05),and the carbon dioxide equivalent slope(VE/VCO2slop)and the Minnesota Living with Heart Failure Questionnaire(MLHFQ)scores of both groups were significantly reduced(P<0.05).The above changes were significantly pronounced in the test group than the control group(P<0.05).The overall incidence of MACEs in the test group(3.28%,2/61)was significantly lower than that of the control group(14.75%,9/61)(P<0.05).Conclusion Quantitative assessment and grading intervention combined with respiratory training can improve cardiopulmonary function,respiratory muscle strength,and quality of life,prolong 6MWD,and reduce MACEs in elderly CHF patients.
