Influences of individualized cardiac exercise rehabilitation training based on metabolic equivalent on cardiopulmonary functions, 6MWT and quality of life in patients with chronic heart failure

AIM To analyze the influences of individualized cardiac exercise rehabilitation training based on metabolic equivalent on cardiopulmonary functions, 6MWT and quality of life in patients with chronic heart failure.

METHODS This study included 110 patients with chronic heart failure admitted to our hospital from June 2020 to June 2022 as research subjects and the patients were divided into control group and observation group according to the random number table, with 55 patients in each group. The patients in control group were given routine rehabilitation guidance, while the patients in observation group were given individualized cardiac exercise rehabilitation training based on metabolic equivalent on the basis of the control group. Cardiac functions were measured by color Doppler echocardiography and cardiopulmonary functions were measured by cardiopulmonary function instrument. 6 minute walking test (6MWT) was used to measure the exercise tolerance and the Minnesota Living with Heart Failure Questionnaire (MLHFQ) was used to assess the quality of life.

RESULTS LVEF in observation group and control group was obviously higher after the intervention than before intervention (all P<0.01) and LVESD and LVEDD were obviously lower than those before intervention (all P<0.01). LVEF in observation group was obviously higher than that in control group after intervention (all P<0.01), and LVESD and LVEDD in observation group were obviously lower than those in control group (all P<0.01). METs, peak heart rate and VO₂peak in observation group and control group were obviously higher after the intervention than before intervention (all P<0.01) and VE/VCO₂ slope was obviously lower than that before intervention (all P<0.01). METs, peak heart rate and VO₂s peak in the observation group were obviously higher than those in the control group after intervention (all P<0.01), and VE/VCO₂ slope was obviously lower than that in the control group (all P<0.01). 6MWT in observation group and control group after intervention were obviously higher than those before intervention (all P<0.01) and 6MWT in observation group was obviously higher than that in control group after intervention (all P<0.01). The scores of symptoms, psychological emotion, physical strength and social limitation in the observation group and the control group were obviously lower after the intervention than before intervention (all P<0.01), and the scores of symptoms, psychological emotion, physical strength and social limitation in observation group were obviously lower than those in control group after intervention (all P<0.01).

CONCLUSION The individualized cardiac exercise rehabilitation training based on metabolic equivalent can improve the cardiopulmonary functions, 6MWT and quality of life in patients with chronic heart failure.
