The Effect of Resistance Breathing Training on Cardiopulmonary Function and Anxiety in Pa-tients with Chronic Heart Failure
[Objective]To explore the effect of resistance breathing training on cardiopulmonary function and anxiety in patients with chronic heart failure(CHF).[Methods]A total of 128 patients with stable CHF were randomly divided into an observation group and a control group,with 64 patients in each group.Both groups of patients were treated with conventional CHF drugs for 8 weeks,and the observation group received respiratory resistance training in combination with drug treatment.Before and after intervention,patients were tested for lung function(FEV1,FEV1/FVC%),6-minute walking test(6 MWT),dyspnea scale(mMRC),and generalized anxiety disorder(GAD)-7 scale,respectively.The cardiopulmonary function,anxiety state,and adverse reactions of the two groups of patients were compared.[Results]After intervention,FEV1 and FEV1/FVC in both groups increased compared to before intervention(P<0.05),and the observation group had higher indicators than the control group(P<0.05).The mMRC grading of the observation group im-proved compared to before intervention(P<0.05);There was no statistically significant difference in mMRC grading between the control group and before intervention(P>0.05),while the observation group had better mMRC grading than the control group(P<0.05).There was no statistically significant difference in 6 MWT grading between the two groups compared to before intervention(both P>0.05),and there was no statistical-ly significant difference in 6 MWT grading between the two groups(P>0.05);The GAD-7 scores of both groups decreased compared to before intervention(P<0.05),and the GAD-7 scores of the observation group were lower than those of the control group(P<0.05);There was no statistically significant difference in the incidence of adverse reactions between the two groups(P<0.05).[Conclusions]The combination of respira-tory resistance training and drug therapy can effectively improve the respiratory function and pulmonary venti-lation function of CHF patients,alleviate negative emotions,and provide a new therapeutic approach for pro-moting patient recovery.
