| Objective:This study sought to explore and examine the effects and effectiveness of Brief Cognitive Behavioural Therapy(BCBT)on perceived control in patients with chronic heart failure.Additionally,it sought to examine the impact of such therapy on their quality of life,levels of depression and anxiety,ejection fraction,B-type brain natriuretic peptide,and6-minute walk distance.Methods:In this study,an experimental-like research design was used to investigate the effectiveness of the recently extensively studied Brief Cognitive Behavioural Therapy(BCBT)in hospitalised patients with chronic heart failure,both nationally and internationally.109 patients who were admitted to a tertiary hospital’s cardiovascular department in Changchun city between June 2021 and June 2022,and met the inclusion criteria,were chosen as the study subjects.In order to prevent sample contamination,Patients were divided equally into two groups according to the duration of their hospital visit and stay: the intervention group receiving brief cognitive behavioural therapy(BCBT)and c usual care consisted of 56 patients and the control group receiving usual care consisted of 53 patients.The duration of treatment was 12 weeks.General demographic information and disease characteristics data were collected at baseline,patients were surveyed and data collated using the Cardiac Attitude Scale Revised(CAS-R),Ejection Fraction,6-minute Walk Test(6MWT),B-type Brain Natriuretic Peptide,Nisurda Heart Failure Quality of Life Questionnaire(MLHFQ),Depression Screening Inventory(PHQ-9),Generalised Anxiety Scale(GAD-7)before they were intervened,as well as after the intervention and six months after the intervention.The collected data was analyzed using IBM SPSS 25.0 software with various methods,including descriptive statistics,independent sample t-tests,chi-square tests,rank tests,repeated-measures variance analysis,and general estimating equation.Results:(1)General information: The differences in general information,disease-related characteristics before receiving the intervention,and disease-related outcome indicators collected d after the intervention did not differ between the two groups(P>0.05),and the two groups could be compared at follow-up.(2)Perceived control: at after three months of intervention,at post-intervention and six months post-intervention,patients receiving cognitive behavioural therapy at both time points had higher perceived control scores than the c usual care group(P<0.05),with different trends in perceived control improvement in the two groups over time(P<0.001),the two groups as a whole were different(P<0.05),time and group did did not interfere with the two groups(P>0.05).(3)Ejection fraction,B-type brain natriuretic peptide and 6-minute walking distance:the ejection fraction in both groups actually increased after the intervention compared to the pre-intervention period,but the difference was found to be insignificant after each statistical calculation and was not reflected in the statistical method(P>0.05);the B-type brain natriuretic peptide and 6-minute walking distance in both groups changed over time(P<0.001);the B-type brain natriuretic peptide in both groups did not change(P>0.001).There was no difference in B-type brain natriuretic peptide between the two groups(P>0.05);there was no difference in 6-minute walking distance between the two groups after the intervention(P>0.05),but there was a difference six months later(P<0.05).(4)Quality of life,depression and anxiety: the quality of life scores were different after the intervention,the intervention group scored lower than the control group(P<0.05),but six months after the intervention there was no difference between the two groups again(P>0.05),the quality of life in both groups increased,higher than before the intervention(P<0.001);the depression and anxiety scores in the intervention group were quite lower than the control group at any time after the intervention(P<0.001),and anxiety and depression levels were much higher in both groups than before the intervention(P<0.05).(5)Subgroup analysis: Sixty-eight patients whose perceived control scores increased after the intervention were compared with those before the intervention.Compared with 41 patients whose perceived control scores did not increase,there was no significant difference in brain natriuretic peptide and ejection fraction between the two groups,while there were significant differences in 6-minute walk distance,quality of life,depression and anxiety between the two groups(P < 0.05).Conclusion:(1)Patients diagnosed with chronic heart failure often exhibit lower levels of perceived control and quality of life,accompanied by mild anxiety and depression levels,rendering early intervention imperative.(2)Brief cognitive behavioural therapy is an effective intervention to increase the level of perceived control in patients with chronic heart failure,improve the level of immediate quality of life in these chronic heart failure patients the level of distant 6-minute walk distance,and reduce the level of anxiety and depression in patients.(3)A long-term research is needed to explore the potential effect of brief cognitive-behavioural therapy on B-type brain natriuretic peptide,ejection fraction in patients with chronic heart failure. |
