Application effects of cardiopulmonary exercise test-based rehabilitation training in patients with chronic heart failure
Objective:To observe application effects of cardiopulmonary exercise test (CPET)-based rehabilitation training in patients with chronic heart failure (CHF). Methods:A prospective study was conducted on 98 patients with CHF admitted to Xinxiang Central Hospital from February 2021 to February 2023. They were divided into control group and observation group by using the random number table method,49 cases in each group. The control group received routine rehabilitation training,while the observation group received the CPET-based rehabilitation training. Both groups were continuously trained for 3 months. The levels of cardiopulmonary function indexes[maximum oxygen uptake (VO2max),anaerobic threshold (AT),maximal voluntary ventilation (MVV) and oxygen pulse]and exercise endurance[6 min walking test (6MWT)],the quality of life[Chinese cardiovascular quality of life questionnaire (CQQC)]scores before and after the training,and the incidence of adverse cardiac events after 3 months of training were compared between the two groups. Results:After the training,the levels of cardiopulmonary function indexes such as VO2max,AT,MVV and oxygen pulse in the two groups were higher than those before training,those in the observation group were higher than those in the control group,and the differences were statistically significant (P<0.05). After the training,the 6MWT distance of the two groups was longer than that before training,that of the observation group was longer than that of the control group,and the differences were statistically significant (P<0.05). After the training,the CQQC scores of physical strength,disease condition,medical condition,social psychological condition,general life function and working condition in the two groups were higher than those before training,those in the observation group were higher than those in the control group,and the differences were statistically significant (P<0.05). Further,the incidence of adverse cardiac events in the observation group was 4.08％ (2/49),which was lower than 20.41％ (10/49) in the control group,and the difference was statistically significant (P<0.05). Conclusions:The CPET-based rehabilitation training in the CHF patients can improve the levels of cardiopulmonary function indexes,enhance the exercise endurance,improve the quality of life,and reduce the incidence of adverse cardiac events. Moreover,it is superior to simple routine rehabilitation training.
