The objective of the present study is to study the relationship between Dyspnoea MMRC grading and Forced Expiratory Volume in first second (FEV1) in COPD patients. This Prospective observational study was conducted on 54 male patients during January2013 and September2014 at Government Chest Diseases and Tuberculosis Hospital, Hanamkonda. Mean MMRC Dyspnoea grading was 2.16 (SD ± 1.05). Pre-bronchodilator % predicted FEV1 values are between 17%-88% with Mean and SD 56.59% ± 18.93%. Post-bronchodilator % predicted FEV1 values are between 16%-88% with Mean and SD 57.27% ± 19.61%.MMRC scale dyspnoea correlated well with Post-bronchodilator % predicted FEV1 (p<0.0001 r = -0.672) more strongly than with Pre-bronchodilator % predicted FEV1 (p<0.0001 r = -0.673). MMRC dyspnoea scale correlated significantly with stage-II of COPD as the study sample had highest proportion of (23/54) Stage – II(r = -0.448 p = 0.03). MMRC dyspnoea grade was inversely correlated strongly with post-bronchodilator % FEV1 than pre-bronchodilator % FEV1. MMRC dyspnoea grade is correlated with GOLD stage – II significantly.
