100 Cases Of COPD Patients With CAT Score Correlation With MMRC Score

Objective:To evaluate CAT Scale chronic obstructive pulmonary disease (COPD) patients quality of life, observe the CAT scores and dyspnea index (MMRC), forced expiratory volume in one second percentage of predicted value percentage (FEV1%) correlation between to observe the different gender, ethnicity, disease complications among groups of COPD CAT score difference. Methods:100 patients with COPD patients with CAT score, MMRC score and pulmonary function test results were relevant to its analysis, calculation of Pearson's correlation coefficient; Statistics 0-4 difference between the degree of difficulty breathing, and evaluation of the effectiveness of CAT sensitivity; and COPD patients without complications according to gender, ethnic grouping, CAT scores between groups homogeneity of variance test applied to different COPD populations CAT observed differences. Results:CAT scores were correlated with MMRC score (rs=0.0.582, P<0.05), forced expiratory volume in one second percentage of percentage of predicted value (FEV1 percentage of predicted value%) were correlated (r=-0.25 P<0.05). MMRC (0-4 points) 5 levels differ between the CAT score (P<0.05). GOLG classification is different between the CAT score (P<0.05). Group with complications and without complications in patients with COPD CAT scores are different (P<0.05), gender (P> 0.05), and different ethnic groups (P> 0.05) There was no difference between the CAT scores. Conclusion:CAT Scale and MMRC, forced expiratory volume in one second percentage of predicted value% related, you can truly reflect the quality of life in patients with COPD, CAT is more suitable for simple evaluation of the quality of life in patients with COPD, CAT can not be used to evaluate patients lung function and disease severity.
