Abstract:
Objective To investigate the correlation between CT parameters of erector spinae muscle(ESM)and pulmonary function in elderly patients with chronic obstructive pulmonary disease(COPD),and to analyze its predictive value for the prognosis of patients.Methods A total of 120 COPD patients were included as the case group(including 60 cases in stable stage and 60 cases in acute exacerbation stage),and 60 smokers were selected as the control group.The differences of ESM CT parameters and pulmonary function parameters in each group were compared.According to the prognosis of COPD,patients were divided into good prognosis group(n=106)and poor prognosis group(n=14),and the predictive efficacy of ESM CT parameters on the prognosis of COPD patients was analyzed.Results The pulmonary function parameters,ESM cross sectional area(CSA)(ESMCSA)and ESM local volume in the case group were significantly lower than those in the control group(P<0.05).ESMCSA and ESM local volume were positively correlated with inspiratory capacity(IC),vital capacity(VC),forced vital capacity(FVC)and forced expiratory volume in one second(FEV1)(P<0.001).The average muscle density of ESM was positively correlated with IC,VC and FVC(P<0.05),but not with FEV1.The area under the curve(AUC)of ESMCSA and ESM local volume in predicting poor prognosis of COPD patients was 0.769[95%confidence interval(CI)0.661-0.876]and 0.827(95%CI 0.734-0.919),respectively.Conclusion There is a certain correlation between the CT parameters of ESM and the pulmonary function parameters of COPD patients,among which the ESMCSA and the ESM local volume have high predictive efficacy for the prognosis of COPD patients.
